1. Foundations of the Theory
This MAL work was initiated and extended by this author since 1965 as a graduate student at Yale University, using MAL as the fundamental principle for systems enzyme kinetics, input-output sequential pattern combinatorial analysis, and both linear and circular general systems [

6,
7].
The input-output patterns (sequential and circular) are systematically analyzed using a combinatorial approach and mathematical induction and deduction to support inductive and deductive conclusions.
The dose-effect or causal-effect relationship in theoretical system biology has been carried out at an optimal homeostatic state at fixed temperature, pressure, oxygen/CO2 tension, and minimum essential nutrients, leaving “dose” and “effect” the only variables, for the decades-long mass-action law (MAL) intrinsic properties explorations and applications. The unified general equations and algorithms of MAL, independent of unit, physical state, size, structure, and complexity, ensure their universality in applications for dynamic, principle-directed design and automated simulation, enhancing efficiency and cost-effectiveness in R&D. Conceptually, this is a fundamental departure from the traditional observation/statistics-based R&D mindset. Thus, the MAL theory provides a paradigm shift in R&D while serving as a complementary, deterministic alternative, like two sides of the same coin, in gaining knowledge, fostering innovation, and driving discoveries.
P = NP in quantum-mechanics-level terminology in quantum computing has sparked broad discussions. Christopher Paradise in 2025 proposed that consciousness itself operates as a polynomial-time solver through entropy-driven self-reference." (Digital Dynamics AI, ORCID 0009-0009-9901-8668). This is a new way of thinking that draws debates on consciousness, intuitiveness, and human cognition.
The P vs NP concept is theoretically relevant to the mass-action law (MAL)-based inputs-outputs sequential transitional-pattern combinatorial analysis, just as AI uses computer programming for question-and-answer. The MAL system-analysis approach was elected as the Ph.D. thesis project at Yale University, L-asparagine biosynthesis by asparagine synthetase, which involved three substrates (Asp, Gln, ATP) and four products (Asp, Glu, AMP, and PP). [

2].
The MAL principle reveals a surprising finding: The discovery of the 2nd-degree (squared) triangle, where all elements in the classical Pascal triangle. i.e., if all elements in Chou’s triangle take square roots, they become the Pascal Triangle.
It is known that in Pascal Triangle (1
st degree), the sum of the reciprocals of the harmonic numbers (1/1 +1/2 + 1/3.+1/4 +1/5 +…) is divergent without a bound. In contrast, the sum of the reciprocals of the triangular numbers (1/1 + 1/3 + 1/6 + 1/10 +…) is convergent to 2. The recent report by Brothers H and Green R showed that the ratios of the sums of sequential rows can lead to Euler’s e-entity. [
https://sciencespetrum.com/pascals-triangle-the secret-within-3d525d88048d],
Interestingly, for the Chou’s Triangle (2nd-degree for SP and PS pattern transitions concept in biological enzyme system), the sum of the reciprocal of the squared numbers (1/1 + 1/4 + 1/9 + 1/16 + 1/25 +….) = /6 = 1.6449…, indicating a transition from the fractions of natural inverted square numbers to a transcendental irrational number that is related to . In addition, the Chou’s Triangle can be related to Riemann’s Zeta Function at Re(2), with a critical line for 1/2, which is corresponding to the MAL-MEE’s Median line at 0.5 for fa = fu = 0.5 for fa + fu =1, i.e., the mathematical function for the fractional distributions of “One”. This is also Chou’s Unity Theory of One (UTO), where MAL-MEE, CIE, and DRIE defined “1” as the universal standard.
The robust growth of the MAL-based R&D theory and its digital simulation method during 2020-2025 has resulted in a net increase of over 11,712 new citations, with a cumulative total of 1,581 citing scientific journals and 1,621 citing patents globally, as reported in bibliometric databases, indicating its game-changing impact.
This report consolidates a unified theoretical and practical framework that charts alternative path to the scientific research and development and digital data science through the Mass-Action Law (MAL) principle and its derived unified general theorems: Median-Effect Equation (MEE) [

Introduction
Two Domains and Ratios
Two domains in Nature, life and non-life, maintain the realm of entity existence through the Doctrine of the Median (DOM) in the Unity Theory of One (UTO) of the Mass-Action Law (
MAL). [
19,
20,
21,
22,
24]
The MAL system analysis on inputs-outputs, does-effect theoretical sequential, pattern, and combinatorial analysis, leads to the derivation of the unified general median-effect equation (MEE):
fa/fu = (D/Dm)m, where D (dose), Dm (median-effect dose), m (exponential dynamic-order), fa (fraction affected), and fu (fraction unaffected); fa +fu =1). Thus, mass and functional effect are interchangeable. The extension of MEE led to the combination index equation (CIE), where CI = 1 (additive), <1 (synergistic), or>1 (antagonistic) for all entity interactions, including drug + drug or drug + radiation. The MAL-MEE is:
fa/fu = fa/(1 -fa) = (fu)-1 -1 = [(fa)-1 -1]-1 = [D/Dm]m, where fa + fu = 1, with general algorithms and the intrinsic properties that manifest Life, that is, in a recyclable, closed form for finite fractional distribution of “1”. The MEE’s floating ratio (fa/fu) has the basic mathematical form of a + b = 1, and a/b = a/(1-a) = (1-b)/b = (D/Dm)m = (M)m, where M is the median-normalized Mass. Thus, Effect (fa) and Mass (D) are interchangeable or equivalent in the life domain. This is akin to Einstein’s relativity theory, E = MC2, in which Energy (E) and Mass (M) are interchangeable or equivalent.
In contrast, the ancient Golden Ratio (GR,
) ,
manifests the Non-life domain, in mathematics and physics, for the continuous fractional distribution of “1”, in open form, extendable to infinity [
22].
Both FR (flexible) and GR (fixed) are dimensionless ratios of relativity due to the cancellation of any unit for the ratio of the same kind, e.g., D/Dm; thus, they are valid independent of unit, physical state, size, structure, and mechanistic complexity, and they are universal. The Dm is a universal reference point, and the dynamics order is a common link; they are universal.
Life and Non-Life
Number scaling such as additive accumulation vs minus deduction, multiply vs divide, exponent vs root, squaring divergence and expansion vs taking root convergence and contraction, can be for real integers or numbers of the number theory, or of the imaginary number, such as i = the exponents show interesting rotational or wave-like properties. Unlike mathematics or theoretical physics, which have , e , i, , and infinity, the life domain uses the natural real numbers as described in this paper. Here, we are specially emphasizing dose-effect dynamics and informatics at the Median, and proximity to the median state of optimal, harmonic, cooperative, and homeostasis biological conditions, which frequently involve receptor, intermediate, pathway, network, systemic coordination and regulation, organization, and environment, in micro and macro scales of structural and functional activities and complexity with hidden behind invisible intermediates processes. Here are the reasons for the MAL-MEE-based theories that have been developed, such as MEP, CIE, DRIE, MTDPT, UTO, and LCU, to reveal the hidden intrinsic properties of natural phenomena. It becomes necessary to conclude that our universe has two domains: Life and Non-Life, each with diverse and complex features. Surprisingly, the fundamental mathematical codes are exceedingly simple: a/b = a/(1-a) for Life and a/b = (a + b)/a for Non-Life.
In biological sciences, the MAL-MEE is defined by general paired parameters: Dm (signifying potency) and m (signifying dynamics-order and shape of dose-effect curves or causal effective graphics).
Life science-based AML-MEE obeys the hyperbolic activation function (m = 1) or a sigmoidal activation function (m ≠ 1), as indicated in computer simulations of biomedical sciences R&D for quantitative digital informatics, and for the AI core-infrastructure algorithm (including the Hopfield’s artificial neural network) for input-output in real-world applications.
The biological MAL-MEE hyperbolic and sigmoidal activation function, fa = 1/[1 + (Dm/D) ^m], turns out to be the common form shared across multiple disciplines, with different symbols and designations.
Life to Death Transition
The abrupt transitions from Live to Non-life are described as: life-or-death in biology, all-or-none in pharmacology, collapse in physics, transformation in engineering and AI, undifferentiable in mathematics. This is a paradigm shift from the “1” distribution functions of the Floating Ratio to the Golden Ratio. In life, the MAL fa from >0 and <1, transform to fa = 0 and fu = becomes meaningless upon death; the Dm from a positive natural number to zero activity (inert), and the dynamic-order, and the m (positive and negative finite number for cooperativity, e.g., .-4 to +4, (or -2 to +2 for optimal cooperativity conditions) depending of negative or positive cooperativity intensity of the system) become zero upon death. Since Dm becomes 0, and the m = 0, (and the exponent of zero to any number returns to 1). Interestingly, when Dm =0, the Floating Ratio, fa/fu = 0/(1-0) = 0. Thus, the Life-Dead paradigm shift transition is beyond any scientific evaluation, but it is a reality. The Life’s homeostasis condition is Dm = fa = fu = 0.5 = 1/2 for equilibrium, symmetry, and harmony state at suitable temperature, pressure, O2/CO2 tension, and minimum essential nutrients for mainlining metabolism, growth, reproduction, and other activities. The importance of the median or 1/2 is manifested by the Riemann’s zeta function ½ critical line, as well as in Alfaro’s Alpha = 1/2. Thus, the clear link between Life and Non-life is via the common code of “1”, but each has distinct distribution functions. Chou’s system analysis on MAL for action (MEE) and interaction (CIE and DRIE) leads to the unity theory of one (UTO), since all MEE, CIE, and DRIE are based on the universal reference of “1” as the standard. Despite FR in Life’s finite, symmetric, closed dynamic properties being basically different from GR in Non-Life’s infinite, open, and recursive dynamic properties, both FR and GR share the ultimate connection as the fractional distribution functions from “One”.
Life is finite, optimal, median-mediated regulatory equilibrium, recyclable, with a “Floating Ratio” of dynamics, consciousness, and intelligence; Whereas non-life function is linear, open, fractal, moldable, with a fixed Golden Ratio, and infinitively expandable; and it is subjected to artificial intelligence (AI) for approximating, mimicking cumulated experience and information of LLMs big data, with extremely high speed and enormous capacity of volume.
Therefore, the Life and Non-life domains need to be separated within causal-effect, dose-response, or input-output scientific R&D dynamics, including AI basic category algorithms, to ensure confusion-free informatics. The best practice is to stay true to the facts and avoid arbitrary, subjective fine-tuning that can change over time, place, and policy.
MAL-Median-Effect Principle for Conserving Energy and Increasing Efficiency
Dm, the general reference point and the dynamic order's common link, exhibits the universal reference standard for equilibrium, optimization, symmetry, harmony, dynamics, and informatics [
24]. The MAL's Minimum Two-dose Data Point Theory (
MTDPT) automatically adds two default points (Dose zero and Dm) to all causal-effect dynamics simulations, resulting in an efficient, cost-effective framework for computerized digital R&D across all dynamics disciplines, including new drug clinical trials.
The MAL-based "
top-down" R&D framework provides guidance for Econo-Green scalable design, in contrast to the traditional, statistics-based “
bottom-up” R&D, when insufficient cumulative general basic knowledge becomes available [
19,
22,
24]. The MAL dynamics enable inter- and cross-disciplinary linkage by sharing a common set of parameters across MAL-MEE/DOM and CIE algorithms in digital data science. By coincidence, the terms bottom, up, top, and down are used in the standard particle physics model for quark designations, with additional charm and strange among them ([
24] in
Figure 32).
Interdisciplinary and Cross-disciplinary Linkage and Convergence
Based on the
MAL-MEE/DOM/CIE/UTO revelation and the fact that humans decide the units and methods of measurement, from a human-centric perspective, Life is proposed to be at the center among the physical elements of Mass, Force, Time, and Space in the Universe. It is called the Life-Centric Universe (
LCU) [
22]. This is not merely technical – it is a manifesto for a new scientific humanism, where it is not just in the universe, but at its center; a new humanism, a Renaissance concept in contrast to the prevailing materialism. It represents a paradigm shift toward unified, efficient, and life-resonant science, especially valuable in the AI and digital R&D era.
In Life, human as a being of primate, decides units and methods of the measurement, produce numbers for counting, sequencing, patterning, combinatorial for count without counting, algebra, geometry, trigonometry, metrics, calculus, metrices, statistics…and evolved to all branches of quantifiable and not quantifiable, countable and not countable sciences, including mathematics, philosophy, physicals, biological and social sciences and arts, whether for theory or for utility. The major scientific disciplines evolved into sub- and sub-sub-disciplines, which in turn ramified into thousands of scientific journals, especially in the biomedical sciences. In current scientific R&D, the diverse independent research works lack cross-linkage because different basic principles, parameters, intonations, taxonomies, and symbols are used, which may lead to unintended consequences for efficiency, cost-effectiveness, and connectivity. The MAL integrated
unified general principle, using common denominators and MAL-parameters, has opened a groundbreaking new avenue for integrated R&D in MAL-based experimental protocol design and MAL-algorithm-based digitalized data simulation, enabling quantitative or indexed conclusions without always relying on the
p-value, which is merely a scientific tool, not the scientific goal. The MAL principle provides common ground that benefits individual researchers and peer reviewers, as confirmed by the global reach of MAL-theory/method bibliometrics. However, the success of this unified, integrative reform task requires the support of decision-makers and key advisors at international regulatory agencies for coordination and harmonization. The preliminary report on MAL-DOM/UTO and LCU has been presented at the American Physiological Society (APS) Summit 2025 in Baltimore, MD [
22].
The full MAL groundbreaking concept innovation has been explored over five decades across various disciplines and journals, making it difficult for any peer reviewer to navigate, except for the speed and capacity of artificial intelligence (AI).

There have been numerous unified general theories of everything, including the Big Bang, relativity, string theory, and fundamental density theory. The mass-action law-based theory, as described here as MAL-MEE/CIR/CIIE/DOM/MDTPT/UTO, and the proposal of Life-Centric Universe (LCU) are based on the real-world, sensible dynamic phenomena, provide quantitative informatics for real-world knowledge innovations and problem solutions, which are supported by detailed scientific derivations, data documentations, and scalable for upward and downward bibliometric evidences. The MAL-unified general principle-guided R&D design and digitalized “top-down” data science is a basic conceptual departure from the traditional observation/statistics-based bottom-up R&D approach.
As indicated above, given the over 30 MAL-theoretical papers spanning multiple journals over five decades, this paper focuses on MAL-Theory rather than the Applications elaborated in 2024 in [
24]. For multi- and cross-disciplinary purposes, some repetition and redundancy in content, as well as self-citations, are unavoidable. This author apologizes to readers for this non-traditional practice and publication format.

The major examples of MAL-MEE-CIE and DRIE applications in specific research disciplines are given for cancer research, anti-viral, molecular biology, cell biology, genetics, immunology, and organ transplant, cancer- and infectious disease- drug discovery (in vitro, in vivo, and in animals), and pre-clinical studies design and implementations, and clinical trials. The applications have inter- and cross-linked to over 100 disciplines and sub-disciplines [

1.1. Mass-Action Law Median Principle for The Unified General Dynamics Theory of All Causal Actions
This paper summarizes a comprehensive theoretical and practical framework that redefines the core of scientific R&D and artificial intelligence through the Mass-Action Law (MAL), and its Median-Effect Equation (MEE), i.e., the Doctrine of the Median (DOM), Combination Index Equation (CIE), and the Dose-Reduction Index Equation (DRIE). These equations embody a deterministic, scalable, and cost-effective dynamical system for modeling actions and interactions in biological, biochemical, and biophysical systems. The Unity Theory of One (UTO), based on MAL-MEE/DOM/CIE/DRIE, leads to the proposition to place Life at the center of Mass, Force, Time, and Space physical elements of the Universe, i.e., the Life-Centric Universe (LCU), in which human decides Units and methods of measurement. The MAL concept integrates philosophy, biology, physics, and AI under a common principle and algorithm, with shared parameters.
The MAL-based biochemical and biophysical general equations show that the four corners are the general theory derived for specific research fields, now widely taught in various textbooks. The MAL-MEE in the center is derived from input (
) and outputs (
) general system analysis of enzyme-catalyzed reactions, with substrates (S), products (P), and inhibitors (I), and combinatorial sequential pattern analysis. The MAL-MEE derivation took 10 years (1966-1976) [
1,
2,
3,
4,
5] and involved system analysis of combinatorial input-output patterns and transitions, involving over 300 reaction rate equations. From MEE to CIE and DRIE took another six years (1977-1984), and the dose-reduction equation in 1988 [
6,
7,
8,
9].
The grand core theory of MAL is the Median-Effect Equation (MEE) as shown in
Figure 1 [
9,
10,
11].
Figure 1.
The Median-Effect Equation (MEE) is the unified form of the major biochemical and biophysical specific equations for specific purposes. The MEE is the unified general theory of the Mass-Action Law (MAL) for pharmacodynamics, biodynamics, and bio-informatics (MAL-PD/BD/BI).

It should be noted that the Michaelis-Menten, Henderson-Hasselbalch, Hill, and Scatchard equations are the “general” theory for a specific research field, not a
unified general equation for interdisciplinary or cross-disciplinary studies. The MEE also covers general dynamics and informatics for action and combination interactions, independent of unit, physical state, size, structure, and mechanistic complexity, with applications far beyond biomedical sciences [
9,
23,
24].
The Doctrine of the Median (DOM) represents an optimal balance in biological systems. The point Dm provides the natural midpoint and universal reference for simulations. It reflects the principle of symmetry, order, balance, homeostasis, and harmony as in classical philosophy.

Mathematical Basic Transformations for Extracting Geometric Properties
The using forward and backward thinking, independent free spirit of exploring curiosity, and referring to ancient philosophy and mathematics, disregards the contemporary popular hot pursuits and timely ideology, the development of the MAL general and unified theory using numbers, sequence, patterns, and systematic combinatory analysis using only the mass-action law as the model, without invoking modern mathematical developments, physics theories, and engineering advancements.
Using the MAL general combinatorial system analysis, surprisingly, simple logic procedures, such as numbers, ratios, constants, equations, reciprocal (and double-reciprocal), logarithmic (and double logarithmic) exponents, dimensions, algebra, geometry, and graphics have revealed numerous intrinsic properties that underlie them, which have become the practical informatics based on the MAL dynamic principle. The limitless applications of the MAL-MEE/CIE/DRIE and the subsequent unity theory of one (UTO) and Life-centric universe (LCU) were not originally expected. The theory of the median-effect equation (MEE), (D/Dm)
m = fa/fu = fa/(1-fa) = (1-fu)/fu = [(fu)
-1 -1 = {(fa)
-1 -1}
-1 , was introduced in 1976 [
4], but the term of the Floating Ratio as the (fa/fu) was named in in 2024 [
20,
22], to compare with the ancient Golden Ratio.
().
A series of MEE defined-dose-effect curves (DEC) can each be normalized by the median dose (DM) to yield first-order (m=1) hyperbolic curves, which can then be normalized into a single curve, for the transformation into a singularity of one (
Figure 2).
Using the MEE algorithm, the MAL principle can be graphically illustrated in various forms, as shown in
Figure 2,
Figure 3 and
Figure 4. The inhibitor (I) is the reference ligand. In contrast, the substrate (S) in the enzyme reaction is the primary ligand [
9], representing the effector in enzyme-catalyzed reactions that exerts an effect on the enzyme target.
The median-point concept [

1.2. Dealing with Biological Complexity and Diversity: The MAL Approach for Solution
1.2.1. MAL-MEE and Chou’s Double Logarithmic Median Effect Plot (MEP): Dynamic Parameters Determination by Computer Simulation
The MAL-MEE/CIE and DRIE-based Theoretical and method, design, and computerized digital simulation [
51,
54,
55] have already been applied to tens of thousands of papers, over 1,500 citing journals, and citing patents [
9,
23,
24,
56,
57], which made a significant contribution with MAL-based efficient Top-Down R&D exploration, innovation, and new drug discovery.
1.2.2. Linearization of the Dose-Effect Curve (DCE)
A typical illustration of the MEE, fa/fu = (D/Dm)
m, is the Median-Effect Plot (MEP), x= log (D) vs. y = log (fa/fu), which transforms the dose-effect curves with hyperbolic shape (m=1) or sigmoidal shape (m
The x-axis represents the logarithm of dose (log (D)), while the y-axis represents the logarithm of the Floating Ratio (log (fa/fu)). The slope of this linear plot directly corresponds to the exponential dynamics order of the m value, and the x-intercept yields log Dm. Thus, the antilog of this x-intercept then yields the Dm value. This linearization for determining the dual m-and-Dm paired parameters of the mass-identity is invaluable because MEP transforms complex sigmoidal or hyperbolic dose-response curves into a straightforward linear relationship, simplifying parameter estimation and enhancing the conceptual insight of all causal-effect dynamics studies. This visual representation underscores how diverse, non-linear dose-effect relationships can be unified and analyzed under a single, simplified linear model, significantly improving the efficiency and predictive power of data analysis (
Figure 3).
Figure 3.
Transformation of various sigmoidal dose-effect curves in real-world problems. (a) into the corresponding linear forms (b) by the median-effect plot (MEP), where y = log (fa/fu) versus x = log (D). The slopes, m values (in this case, equal to 2, 3, and 5 for curves a, b, and c) signify the degree of sigmoidal shape. The anti-logs of the x-intercepts on the axis, where fa/fu = 1 [or log(fa/fu) = 0], give the Dm values, which signify the potency of each drugs, such as ID50 for median inhibition, ED50 for median effect, TD50 for median toxicity, and LD50 for median lethality, that forms the horizontal median-effect axis in pharmacological, medical and biological research and development (R&D), and beyond.

Thus, the
median-point concept is extended to the
median-axis concept. The rotation of the median axis may result in the median plane in computerized simulations [

31].
Throughout this paper, based on the MAL-MEE principle, the diversity of phenomena in nature is merely the variability in the distribution functions of “1”.
1.2.3. Exponential Cooperativity Function and Intermediates, Pathway, and Network in the Life Science Features
The overriding features of the biomedical sciences and most other disciplines are the complexity and diversity of events and phenomena at micro and macro scales. The major reasons are the underlying intermediates, pathways, and networks hiding behind the input and output processes of the causal-effect or dose-effect, and the fundamental principles’ intrinsic properties. The MAL is shown to be the unified general principle in Nature.
Life science has the unique properties of functional cooperativity, equilibrium, feedback, symmetry, and harmony as basic features.
Figure 4A,B illustrate some of these properties.
Figure 4.

x = log (d) versus
y = log (fa/fu), which is also equal to log [(fa)
-1 – 1]
-1. The MEP linearizes the dose-effect curve (DEC) into a straight line, as shown in
Figure 4A,B. After multiple paired-dose and effect data entries, the computer software automatically performed the MEP to determine the paired dynamic parameters (m from the slope and Dm from the x-intercept), and then, using Dm-m values, generated the DEC in reverse.
Since any two dose-effect data points lie on the same straight line, they represent the entire straight line and thus the full dose-effect curve, provided at least two data points are available. Drawing a curve from only two points is a historical breakthrough because it is counterintuitive. The MAL-MEE/MEP, in fact, adds two default points (dose zero and Dm) into all dose-effect dynamics relationships. Chou called this the Minimum Two Data-Points Theory (MTDPT) for efficient, cost-effective, and econo-green in all causal-effect R&D (see
Figure 5 below) [

Despite different curve shapes in a linear scale, all follow the unified linear form in the median-effect domain. This linearization of DEC by MEE/PEP leads to the minimum two-dose data point theory (MTDPT) (see below).

1.3. MEP Linearization Leads to MTDPT: The Basis for Efficient, Cost-Effective, and Econo-Green R&D
Q: How to draw a curve from two points?
(A historically fundamental anti-intuitive question)
A: Yes. It can be done. Ask MAL-MEE/MEP/DOM what makes the magic.
Linearization of Dose-Effect Curves (DEC) of different shapes and different potencies with a Minimum of Two Dose-Data-Points Theory (MTDPT). The MDDPT introduced a groundbreaking concept in digital informatics for system biology through computer simulation, reducing the size of all dynamic studies. The MAL-MEE/MEP algorithm automatically adds two default data points (Dose zero and Dm) in all DEC.
One can draw a specific dose-effect curve with a theoretical minimum of 'only two-dose data points' - One default Point is Dose Zero, and another default point is the Median-Effect Dose (Dm). Any 2-data points on a straight line represent the same line, and therefore, the same DEC. The MTDPT is the theoretical basis for efficient, cost-effective, and “Econo-Green” Biomedical R&D and drug evaluations, especially in animal studies and in the design of clinical trial protocols. [11, Chou TC. Integrative Biol. 3: 548-559, 2011; Pharmacological Rev. 58: 621-681, 2006 [
9].
The Dose-Effect Curves (DEC): with different “shape” and “potency” simulated by MAL-MEE/MEP are shown in
Figure 5, which indicates the theoretical basis for efficient and cost-effective R&D, MTDPT.
1.3.1. The Prerequisite of MAL-MEE Entity’s Paired ID Parameters, m and Dm Values
The mass-action action, as expressed by the MAL-MEE-MEP, has three components to consider in Biomedical or Life Science Applications:
Mass and Action: It refers to any entity that causes or exerts a specified effect. For example, in biomedical sciences, it can be a chemical dose, such as a drug, inhibitor, activator, modulator, or regulator; in physical dose, it can be radiation, thermo-, photo-, UV, microwave, etc.
Receptor or Target: For a specific effect to occur, there must be a recipient, such as a molecule, cell, organ, body, or environment. Usually, there is an affinity or cooperativity between the effector and the recipient for the action. These are scientifically in terms of affinity constants and/or dissociation constants.
Scope of Effect and Target: No limit. (to the limit of accuracy of measurement technology)
Dose Number, Range, Density Gradient
Unit and Quantifiable Measurement
Dose-response or Dose-effect Relationship
Plan and Protocol Design, and the endpoint of measurement
Schedule or Regimen (e.g., clinical trials)
Input-Output (visible) and Intermediate (Usually not visible)
All the above considerations have been tested in the MAL-MEE-CIE-DRIE applications, as indicated in the bibliometrics.
1.3.2. The MAL-MTDPT: A Game Changer
A groundbreaking discovery was not originally expected, since it is rather anti-intuitive:
This is the Minimum Two-Dose Data Point Theory (MTDPT), which allows one to draw a curve from two points. MAL-MEE’s Median-Effect Plot (MEP) linearizes all dynamic dose-effect curves into straight lines,
Thus, MAL-MEE-MEP with log D vs. log (fa/fu) plot, automatically adds two default data points (dose zero and Dm) into considerations, thus allowing a smaller number of data points requirement in R&D. This leads to efficient, cost-effective, and Econo-Green R&D, which saves time, effort, and resources.

When the Median-Effect Equation was published in 1976 [
4], it was mistakenly regarded as equivalent to the Hill equation. In fact, they are derived from completely different methods and purposes: MEE is derived from MAL inputs-outputs combinatorial general system analysis, which took 10 years (1966-1976) and involved 300 reaction-rate equations. Whereas the Hill equation is specifically derived from a specific purpose for higher-order ligand interaction (e.g., oxygen hemoglobin), as shown in
Table 1 [
9].
1.3.3. Different Derivation Approaches Between the MEE and the Hill Equation
The MEE and Hill have similar mathematical forms, but they differ fundamentally in their derivation. In addition, MEE is the unified general theory, whereas the Hill equation is the specific general theory. The Hill equation invokes Vmax, whereas MEE does not. Vmax is difficult to measure accurately without extrapolation. The MEE’s Dm value is easily determined by comparing the Vmax value.
Table 1.
Comparison of the MAL-MEE/MEP theory/equation with the Hill equation.
Table 1.
Comparison of the MAL-MEE/MEP theory/equation with the Hill equation.
The complexity, perplexity, and diversity of biomedical and natural phenomena lead many scientists to seek solutions or approximate causal dose-effect relationships. The MAL-MEE is the
unified general principle, and the Hill equation is a
specific general principle; they are derived from completely different ways. The MEE was derived over 10 years (1966-1976) and involved more than 300 reaction-rate equations [

5,

9].
1.3.4. Comparison of MAL-MEE and Statistical Functions
Among thousands of mathematical equations or formulas in scientific literature, only a small fraction of them are relevant to the biological observations. Since the 20th century, several major schools of thought have emerged, including the mathematical, statistical, and physical-chemical schools, such as the MAL.
Table 2 compares the Power Law, Logit, Probit, and the MAL approaches [
9].
The Power Law and Logit are simple to use but lack a theoretical basis, amounting to intuitive approximations. The Probit is rigorously developed from statistical principles, but is too complex for practical use.
By contrast, the MAL-based MEE, as focused in this paper, provides equations/algorithms/computer software. The Floating Ratio of MEE enables universality and the scale-up of single-entity actions to multiple-entity interactions, enabling ubiquitous applications. These are supported by citations in tens of thousands of papers, in over 1,500 journals, and in patents [

The statistical functions always introduce some uncertainty, unless the p-value is approaching zero.
The functions involving e have been difficult to handle with deterministic approaches in real-world problem-solving, such as in the biomedical sciences.
1.4. The Doctrine of Median: Unified General MAL-MEE Theory
1.4.1. Input-Output Activation Function and Algorithm in Dynamics
The median-effect equation (MEE) can be rearranged for different representations:
|
|
|
| Effect (Force) vs. Mass |
Input (↓) |
Output (↑) |
where
D is dose, Dm is median-effect dose, fa and fu are fractions affected and unaffected, respectively, (i.e., fa + fu =
1), and m is the exponential dynamics-order, that signifies the shape of the dose-effect curve, in hyperbolic activation without cooperativity (
m=1), sigmoidal for positive cooperativity and activation function (m>1), and flat sigmoidal negative cooperativity and activation function (m<1) [
4,
9,
11].
1.4.2. The Median-Effect Plot (MEP) is the Log-Log Plot for the MAL Bioinformatics.
Before the computer era, engineers used logarithms for calculating rulers. Biologists had frequently used the logarithmic scale to constrain out-of-the-map data points. The MAL-MEP adopts the double-logarithmic plot, log (D) vs. log (fa/fu) (or vs. log [(fa)
-1 -1]
-1), called the median-effect plot (MEP) [
4]. This is for theoretical reasons: linearizing all dose-effect curves (DEC) to extract the fundamental digital parameters of both Dm for potency or efficacy and m for the dynamic-order and shape of DEC, based on the MAL-MEE principle.
The y = ax + b type form, linearity principle, leads to the m and Dm digital informatics simulation/determination, since the slope gives the m value, and the x-intercept gives the anti-log of Dm, thus the Dm value, automatically by computer simulation [
4,
9,
23]. It also leads to the minimum two-dose data point theory (MTDPT) for far-reaching impact for efficient, cost-effective, and eco-green scientific research and development (R&D), since MEP adds all DEC two default data points, dose-zero and Dm, embedded in all computer simulations [
11,
14,
15,
16,
17,
18,
19,
20,
21,
22,
23,
24]. This MAL-MEE/MEP/MTDPT has historical advantages over the traditional empirical curve-fitting or statistical R&D approach.
1.4.3. The Floating Ratio and the Mass/Mass (D/Dm) Ratio:
Fa and fu per se are fractions, thus have no unit, whereas D/Dm represents the same kind of entity-unit ratio cancellation; and m is just the exponential number that exerts mathematical properties and graphics. Note that the intermediate steps (e.g., between input and output are not visible (e.g., fu = 1-fa), but they are embedded in the floating ratio and the distribution function of “1” of the MAL-MEE. (see illustration late in
Figure 10).
The simplicity of the MAL-MEE is not reducible; D/Dm is a dimensionless ratio for universality, and the median normalized dose is D/Dm = M (general mass). The MAL-MEE, fa/fu (floating effect relativity) = Mass at any given dynamic-order (m). Therefore, the MAL-MEE indicates that “Effect” and “Mass” are interchangeable or equivalent. This MAL-MEE in biology is the counterpart of Einstein’s relativity theory, E = MC2 in physics, which indicates that “Energy” and “Mass” are interchangeable or equivalent. The difference in meaning is just life science’s “functional effect” vs. physical science’s “energy force”.
The MAL describes dose-dependent input-output relationships in biological systems, with a variety of intermediate transitions, such as enzyme-catalyzed reactions, receptor-mediated pharmacological effects, sensory signal reception and motor actions, and network pathway connections and regulations. This causal effect relation occurred in biology and in non-life sciences, such as the Langmuir adsorption isotherm and questions-and-answers, as well as in contemporary artificial intelligence (AI).
In the MAL-MEE, both the left and right of fa/fu (for function) and D/Dm (mass) are ratios of the same kind. These ratios represent a universal property that is independent of dimensions, units, size, physical state, and the system's complexity. They remain valid under various conditions, such as time and space, especially with respect to geometric properties. We can also view dimensions as independent entities with perceptions and senses, like the median-effect point at (0, 0, 0), and the median-effect axes at (0,1,1), (1, 1, 0), (1, 0, 1,0,1), and (1, 1, 1). The x-, y-, and z-axes help describe the position of any point in three-dimensional space, along with their rotations, as seen in
[71,72,73]. Using physical and mathematical hypotheses to explain otherwise difficult phenomena- such as gravity, negative dose (see below in
Figure 21), anti-matter, dark matter, quantum entanglement, exclusivity, competitiveness, synergism, antagonism, or the abstract concept of exclusivity (see
Figure 16 and
Figure 17 below), and harmony (see
Figure 37 below)- is a common approach.
1.4.4. Dm Is the Harmonic Mean of Kinetic Constants
The MEE indicates that dose and effect are interconvertible. In addition, Dm is the universal efficacy reference point and the common link among dynamic orders [
3,
9,
24]. Furthermore, Dm is the harmonic mean of kinetic constant kii and kis in the Lineweaver-Burk plot. When kii = Kis (or Kii/Kis =1), it means pure non-competitiveness; it also means “pure harmony” [
24]. (This phenomenon is illustrated later in
Figure 37.
1.5. MAL Theory/Algorithm Rationale and Scalability
Beyond 3D, we need to use analogy, projection, reasoning, and inference. We can lift, bend, cut, or poke the paper to reveal different features. We can also hold a hypercube with cuts from various angles and positions to produce different shapes, curves, and volumes. Many hidden secrets can be revealed by the “One” entity. Therefore, the unified general theory of the mass action law is important for developing general, efficient, and effective basic R&D and AI reasoning models [

55].
From the relativity ratio property, the MAL-based MEE/CIE dynamic theory or doctrine of the median (DOM) has dimensionless, universal applications without limit. It is logical to address real-world situations and problems as a priority before we attempt to solve abstract concepts, complex mathematical equations, or formulas. It is astonishing to note that international FDAs, with so many regulations, rules, and guidelines, still have no clear definition for “What is the exact definition of the additive effect of two drugs? Or more drugs?” [
9]. The integration with MAL (or other means) for a unified, general principle of digital science to support intra-, inter-, multi-, and cross-disciplinary linkage is desperately needed for efficiency, cost-effectiveness, and digital informatics. The biological sciences have ramified into over 4,000 journals for R&Ds, most of which concern specific molecules, cells, organs, and diseases in biochemistry, physiology, pharmacology, infectious diseases, and cancer research, using independent, different principles and parameters in vitro, in animals, and in clinical trial protocol design and data analysis. Advocacy for R&D regulatory policy reform and modernization, using a unified set of principles and parameters for R&D, has been called for multiple years to reduce costs, increase efficiency, conserve laboratory animals, and reduce the number of patients in clinical trials, without a unified, general integration principle.[

24,

30,
31].
Four advanced AI models (ChatGPT 5.1, DeepSeek R1 V3, Gemini 3, xAI Grok-3, Qwen 2.5 Max) have independently assessed Ting-Chao Chou’s work (1970-2025) on MAL- MEE/CIE/DRIE/DOM/MTDPT/UTO Theory/algorithms and applications. This includes a book [
24] with 11 chapters and the APS-Summit-2025 abstract [
22]. These independent models validated the significance and practical implications of this MAL unified general theory-based “top-down” R&D framework, which is opposite, yet complementary, to the centuries-old traditional, statistics-based “bottom-up” R&D [
19,
20,
21,
22,
24]; like front and side/rear views of the same entity, or two sides of the same coin.
Human intelligence is different from artificial intelligence (AI). AI, as a physical entity or tool, collects, stores, and utilizes a vast amount of human-recorded information and knowledge using human-derived/selected algorithms, at the speed and volume that makes the magic. The numerous repetitive and retrospective processes make approximation, mimicking, and superposition near-perfect. Still, the irrational “e” functions used in mathematics, statistics, physics, and AI make it not a perfect fit to the real-life features and properties that are finite, closed, and circular (e.g., the Floating Ratio), but not extendable to infinity (e.g., the Golden Ratio). Thus, we face Life and Non-life as two separate domains in the universe and in reality.
In both scientific R&D and AI development, the simplicity, generality, efficiency, and cost-effectiveness of algorithms will be the key determinants in the framework for categorizing trillions of information bits in LLM models, enabling them to succeed in real-world applications. The human brain has about 86 billion neurons; the efficiency of the functional neural network is truly remarkable.
1.5.1. MAL Reveals A Conceptual Departure from Traditional R&D Observation-Statistic-Based R&D Approach
The MAL-MEE/DOM algorithm automatically adds two default data points (Dose-zero and Dm) to all dose-effect data analysis and computer simulation, including animal studies and clinical trials. It instantly generates quantitative, digitalized conclusions in tables and graphics. This is the Minimum Two-Dose Data Points Theory (
MTDPT) [
9,
11,
24], which serves as the basis for a cost-effective, Econo-Green scientific R&D platform, particularly for costly animal studies and clinical trials.
1.5.2. The Broad Applicability in Life Science and Beyond
The MAL-MEE-dictated combination index equation. All MAL-based MEE, CIE, and DRIE can be and have been applied for in vitro, in vivo, animal studies, and clinical trials, by automated computer analysis and simulation following a few pairs of dose-effect data entries, when using the MAL dynamics-based simple design, for efficient, cost-effective, Econo-green R&D. MAL-theory/algorithm [
9,
11,
19,
20,
21,
22] has applications in biomedical sciences, and beyond, including biophysical, environmental, agricultural, marine, toxicological, and food sciences [
24,
31,
45,
55].
Furthermore, the MAL-based experimental design allows experimental results to be subject to automated computer simulation in seconds, including [
9,
24,
53,
54,
55] :
Construction of MEE-MEP to obtain the paired Dm and m values; In return, these parameters generate the dose-effect curve (DEC).
The MAL-based computer, such as CompuSyn or Calcusyn, will also display dose and effect data content and tabulation, scheme of layout, and conclusions.
This MAL data science theory and method is not only applicable for the single drug or single entity, but also applicable to multiple drugs or entities in combinations (e.g., drug + radiation) [
9,
15,
24].
The dynamics of entity actions and interactions in molecular and cellular biology, genetics, cancer research, anti-microbials, and pharmaceutical drug evaluation are studied using digital computer simulations, innovation, and drug discoveries, as well as signaling pathways and network interactions.
The overviews are available in [
9,
10,
11,
12,
24]. Specific examples, including PD design and planning, data entry, precautionary note, automated computer simulation, and full CompuSyn Report printout, for in vitro [
8,
12,
29,
31,
34,
61,
62], in vivo and in animals [
24,
43,
45], and other studies, are illustrated in [
24,
55]. All these broad applications of MAL fundamental principles are documented in the scientific citation database collections [
56,
57,
58].
1.5.3. The Game Changer of MAL-MDTPT in Overall Causal-Effect R&D
The MAL-MEE-PEP Design Resulting in Using as few as 10-fold Less Patients in clinical trials
In health science research and development, although molecular, cellular, and in vitro studies lay the scientific foundation for further exploration, the reality test will be animal studies and clinical trials, which are specifically aimed endeavors and have been proven to be laborious and costly. In the absence of a unified, fundamental principle, trial-and-error has been the only mainstream approach to knowledge and solutions since antiquity.
This traditional observation-specific statistical approach is termed the “bottom-up R&D,” in contrast to Nature’s unified general MAL theory-guided “top-down R&D” [
9,
14,
15,
16,
17,
18,
19,
20,
21,
22,
23,
24]. There are clearly different meanings and scopes of validity between specific general equations (such as the Michaelis-Menten, Henderson-Hasselbalch, Hill, and Scatchard equations) and the unified general theory of the Median-effect equation of the mass-action law, as shown in
Figure 1.
The MTDPT Concept of Small-Size Data Sets for Cost-Effectiveness
The MAL-MEE/MEP theory/equation/algorithm/simulation and mathematical transformation lead to the minimum two-dose data point theory (MTDPT) for all dose-effect curves by auto-adding two default data-points (Dose zero, and Dm), which is the universal reference point, and dynamic orders common link; Thus, this requires smaller-sized experiments in R&Ds [
9].
The MAL-MTDPT allows a smaller size, requiring two fewer data points, by automatically adding two data points, dose-zero and median dose, to all causal effect analyses for simulations of experimental data. This is particularly beneficial for costly, time-consuming animal studies and for clinical trial protocol design. In addition, the MAL-MEE/MEP dual parameters (Dm and m) guided the dose-number, dose-range, and dose-density planning.
The MAL Design Used Ten-Fold Fewer Patients in Anti-HIV Clinical Trials than the Traditional p-value-Based Design. Yet, the MAL Provides Quantitative Conclusions.
Therefore, MAL-MTDPT automatically conserves laboratory animals and reduces the number of patients in Phase I clinical trials by as much as tenfold compared with the traditional observation-probabilistic design based on the p-value [
60], particularly in Anti-HIV clinical trials, where clinical results can be quantitatively assessed. More details of comparisons are given in the later Section of this paper, and
Appendix III.
1.6. The Ratio Is Relativity
Across the scientific disciplines, regardless of life and non-life, the basic tool of “ratio” plays a prominent role. The following are some examples.
1.6.1. Golden Ratio vs. Floating Ratio: The Distribution fraction of “1”
The subjects of comparing the ancient Golden Ratio,
(
GR) with the modern Floating Ratio fa/fu, (
FR), of MAL-MEE/MEP have been raised and discussed recently, since 2023 at scientific society meetings [
14,
15,
16,
17,
18,
19,
20,
21,
22]. However, the idea of
DOM vs. UTO for inter- and multi-disciplinary linkage for efficient, cost-effective digital R&D has been advocated for over three decades [
9,
11,
24].
Figure 6 illustrates the properties of the Golden Ratio.
1.6.2. The Floating Ratio Manifests Life and The Golden Ratio Manifests Non-Life: “1” Becomes the Common Link
The Floating Ratio (FR) or fa/fu is the integral part of the Median-effect equation (MEE), fa/fu = (D/Dm)m, which is the grand principle of the MAL that underlines the dynamics and informatics of life science. This unique feature will be discussed in the cross-disciplinary context of this paper.
Table 3 compares and summarizes the basic properties of the life-science-based Floating Ratio vs. the mathematics- and physics-based ancient Golden Ratio.
The GR () manifests in the Non-Life Domain.
In contrast to MAL-MEE/DOM/CIE life science indicating FR = fa/fu, the ancient Golden Ratio, GR (
), is an imaginary, transcendental constant, in mathematics and physics (i.e., non-life domain), which is:
is greater than 1, and is an irrational, infinite number obtained from physics and mathematics, which belong to the non-life domain.

In life science, the mass-action law (MAL) relates Mass and Action, where action requires energy, calories, and effort. The causal dose (D), input (↓), produces the consequential Effect (fa), which is the output (↑). Based on the MAL-MEE/DOM, (D/Dm)m = (fa/fu), Dose (D), is generally normalized with the universal reference dose, Dm, thus D/Dm refers to mass (M) in which unit is cancelled out as an Identity, and fa/fu ratio refers to the Floating Ratio of Effect which manifests Live. The abrupt paradigm shift from Life to Non-Life is a transcendental transformation that remains scientifically unresolved.
The only links between Life and Non-Life are the distribution functions of “1” for FR and GR, and the fact that the rational MAL function can be transformed into imaginary or transcendental numbers, such as the negative and positive dose, which are interchangeable via MAL-MEE (
Figure 21). Pascal’s triangle’s consecutive rows ratio real numbers can lead to Euler’s
e (see
Section 8.9), and the MAL-MEE and Riemann’s zeta function lead to an irrational number (π) (see
Section 1.12). In the Floating Ratio, input dose (fa) is visible, and fu and (fu)
– 1 – 1 are not visible (not real), but interrelated to “1” (see
Figure 11).
1.6.2. The Ratio of Mass, Force, Time, and Space
The ratio cross-links disciplines. The ratio of the same kind cancels any unit, thus becoming dimensionless and independent of units, physical states, size, structure, and complexity.
The equal “=” sign indicates equivalence. Thus, Dose and Effect, Force and Mass, Energy and Mass are equivalent or interchangeable, as indicated below:
In all, mass is M or m, and Effect, Force, and Energy are equivalent.
1.6.2.1. The Life Domain Floating Ratio
The Floating Ratio, FR, (fa/fu): The mass-action law median-effect equation (MAL-MEE), fa/fu = (D/Dm)m, is the fundamental principle of biomedical and biophysical science in the life domain.
1.6.2.2. The Ratio Revelations in Life Sciences and Physical Sciences
-
The Floating Ratio: For the MAL, (D/Dm)m = fa/fu; fa + fu = 1. For the Floating Ratio, fa/fu, when Fa = fu, the Median = 0.5 = ½.
The fundamental mathematical form is:
a/b = (1-b)/a = a/(1-b), where, a + b = 1 (for Life).
-
The Golden Ratio (
): It is the fixed ratio in the form
= 1.618033…= (1 + √5)/2.
The fundamental mathematical form of the Golden Ratio is
a/b = (a + b)/a = 1 + b/a (for Non-Life).
The Newton’s Ratio: The ratio of Force and Mass. For Newton’s Law of Motion, F = M a; F/M = a
-
The Einstein’s Energy/Mass Ratio: For Einstein’s Relativity Theory, E = MC2; E/M = C2
The Fundamental Density Theory (FDT) Ratio: E/m = c² = 1/(ε0 μ0) = (d/t)²
Where quantum mechanics (left), electromagnetism (middle), and general relativity (right) are three perspectives on the same geometric reality, related to space-time. It perceives ‘mass” as a geometric property of the omnium field. This omnium field, in a way, is akin to the MAL-MEE/CIE’s Unity of “one” theory (UTO) universal generality.

67]: This is a new theory that makes grand claims, although detailed derivations and broad examples of applications remain to be confirmed. However, numerous analogies and equivalencies have been established for general principles in real-world life sciences in MAL. In particular, the MAL vs. Omnium, as well as the Median (point, axis, and plane) vs. Alpha = ½ = 0.5, show close co-incidence.
In physics, FDT, D for “Density” is the ratio of the object’s mass to volume, which is equivalent to “Concentration” in biology (e.g., molar, millimolar). The millimolar (mM) unit of concentration is equal to one-thousandth of a mole per liter, or 10^-3 M. It represents the number of millimoles of a substance dissolved in one liter of solution. It is commonly used in chemistry for convenience. The mass-action law is considered the fundamental principle of both biochemistry and biophysics.
FDT in physics is a relatively new concept (2024-2025); energy per mass, electromagnetic impedance, and spacetime kinematics all express the same geometric invariant [
68,
69,
70]. FDT adds one control dial — alpha — that tracks how close the system is to the maximum-density shell at the Schwarzschild radius (Rs). The Alpha outside/inside concept in FDT is similar to fa/fu in MAL-MEE, where the Median (DM, 0.5) is the same as alpha = 1/2. Since fa + fu =1, then outside + inside = the whole. The Omnium field refers to the Universe of the physical domain. MAL-MEE connects both line and non-life domains.
In FDT, alpha (outside): alpha = Rs / r, alpha (inside): alpha = r / Rs, and Maximum density: alpha → 1 from both sides. The physical meaning of r is related to the range of alpha values.
That’s where hard MeV emission and extreme collimation live. C is not just a speed limit; it’s the ratio that defines how distances and durations relate [
70]. Particles formed under identical conditions inherit identical geometric properties.
Alfaro claimed that the 1997 Williamson-van der Mark “photon as electron” model and FDT’s helical-light framework are mathematically identical descriptions of the same object: the electron is confined light, almost everything else follows:
E/m = c² is an identity, not a slogan; The distinction “photon vs electron vs graviton vs
Gluon” is a density/regime label, not four different particles.
General relativity (GR) and quantum mechanics (QM) emerge as limiting cases of a single density parameter alpha FDT in (0,1).
The isotope ratio: In science and history, another interesting ratio is C14 Dating, where the C14/C12 ratio provides an estimate. This is another utility of the natural ratio.

The e/m Quantum Ratio: Recent report on measuring the Charge (e) to Mass (m) ratio [
104] using the definition of centripetal acceleration and Newton’s second law to get an expression for the radius (R) of the circular motion, and obtain the relationship of: R = mv/eB, where v is speed, and B is magnetic field.
Using the change in electric potential (ΔV), the strength of the magnetic field (B), and the radius of the path (R), the following expression for the charge-to-mass ratio of the electron (e/m) results.
The radius depend on the charge (e) to mass (m) ratio as well as the speed (v).
Plotting R² vs ΔV should create a straight line. The slope of this line would be 2/(B²(e/m)), which we can use to then solve for e/m.
Pascal Triangle Rows Ratio: The ratios of the serial rows lead to Euler’s
e (see
Section 8.9).
Different scientific disciplines use different symbols, terms, and definitions for different goals. In most cases, basic mathematical concepts or maneuvers, such as ratio cancellation or normalization, reciprocal (and double reciprocals), and logarithmic (and double logarithmic) exponentials and roots, reveal hidden intrinsic properties that are otherwise not visible (or sensible). Many of them involve 1, 0, median, duo, etc. Some involve imaginary or irrational numbers, transcendental numbers, or complex numbers such as e, i , In life science MAL dynamics, the most relevant numbers are 1, 0, and the median (1/2 or 0.5).
1.7. Unity Theory of One and Life-Centric Universe
The MAL-Based MEE/CIE/DRIE/DOM leads to the unity theory of one (UTO) or the distribution function of “1”, with or without the “e” properties (
Figure 7).
The MAL theory has a mathematical form of a/b = (1-b)/b = a/(1-b), and a + b = 1, when a/b =1. Then, a = b =1/2 = o.5 in the “median”, as indicated by the MEE: fa/fu = (D/Dm)m = (M)m where M is the median-normalized dose, i.e., the median-dose as the dose unit.
1.7.1. Math Form: MAL-MEE in Biology Compared with the Fermi-Dirac Equations in Physics
In
Figure 7, different disciplines with different scientific denotations share the same basic mathematical form, except that the Fermi-Dirac distribution equation contains “e”. In MAL-MEE, D/Dm is a dimensionless relativity ratio, independent of unit, size, structure, state, and complexity.

1.7.2. MAL-MEE-UTO Points to Life-Centric Universe (LCU) Interfacing with Physical Elements
Summing up the above MAL exploration since the mid-1960s, the mass-action law (MAL) in Life science can be described by MEE/CIE/DRIE, DOM/MTDPT. This Unity Theory of One (UTO) leads to the proposal of a Life-Centric Universe (LCU), as indicated in
Figure 8. It explains that the universe has two domains: Life and Non-Life, realms by the “One” and the “Median”. The graphic layers in
Figure 8 were created with assistance from ChatGPT.
Figure 8.
The mass-action law median-effect principle in life sciences leads to MEE/CIE/DRIE/MTDPT/DOM, the Unity Theory of One (UTO), which in turn proposes a Life-Centric Universe (LCU) with two domains: Life with fundamental code a/b = a/(1-a), a + b =1 (finite and circular), and Non-Life with fundamental code a/b = (a + b)/a (infinite and open). Life (inside the large cycle) interfaces with the outside existence of the non-life domain, such as the Environment, Physics, Mathematics, and Intellectual Dynamics-Informatics, in small circles.

As indicated above, the grand theory of the MAL, the median-effect equation, fa/fu = (D/Dm)m, both right and left sides are the relativity ratio in the simplest form, based on the ratio-cancellation principle, the MAL-MEE application is independent of unit, physical state, size, structure, and mechanistic complexity, ensuring its universality.
1.7.3. International SI Unit Defined by Human
The international SI unit designations, shown below (
Figure 9), were designed by humans and facilitate inter- and cross-disciplinary linkage.
Mass:Weight of entity, effecter, effected, substrate, receptor, intermediate entity, products, input entity, output entity, drugs, chemicals, biologicals, receptor…
Force: Energy, temperature, electromagnetic weak and strong force, gravitational force, action/interaction/ reaction, attractive/repulsive, effect, response, activation/inhibition, synergism/antagonism, potentiation/suppression, regulate, feedback, competitive/noncompetitive/uncompetitive, aggressive/peace, equilibrium, affinity, and harmony...
Space:Size, volume, distance, location, inclusivity, exclusivity, non-exclusive, inclusive, vector, superposition, symmetry…
Time:Moment, time-lapse, period, rate, speed…
Life:The dynamics of all components above are mixed with units and measurements decided by humans. Life includes birth and death, growth, rest and movement, metabolism, reproduction, consciousness, intelligence, the survival instinct, the existence instinct, ecosystems, and AI.
Figure 9.
All units are derived from the seven SI units. Blue lines show when a unit is multiplied. The red indicates a division. Count the arrowheads to see how many times a division or multiplication takes place. You will see that the mole has no derived unit, and that the base units do not define the radian or the steradian. A radian is the angle of an arc that has the same length as the radius. A steradian is the angle of a cone of a sphere where the area of the base of the cone is the square of the radius of the sphere.

1.7.4. Number, Ratios, and Identities: Real and Imaginary
The Unity Theory of One (UTO or UOT), with a distribution function of One, especially in the hyperbolic and sigmoidal activation function, of the Doctrine of the Median (DOM), with a Median Point, Median Axis, and Plane. Different disciplines have their own annotations, units, and definitions. However, they converged into the concept of One, whether real or imaginary, transformational or transcendental.
The Mass and Median mediated Floating Ratio (FR), fa/fu = fa/(1-fa) = [(fa)-1 -1]-1 = (D/Dm)m, indicating Life is the center of Mass Force, Mass, Space & Time to constitute five Components of the Universe.
Many entities and identities in Nature exist without knowing their source. Who, why, when, where, decide them, a priori? These are discovered, described, and utilized by humans but not created by humans. Humans are gradually understanding the meaning of the revelation of intrinsic properties, via extrinsic phenomenal investigation. We found the Unity of “One” and Life-Centric Universe, whatever that “One” is. Many civilizations in human history tended to believe in the existence of “God” or All the Mightiest” as the “One”. Given below are some examples.
Examples of numbers, entities, identities, and ratios: Real and Transcendental. Nature’s open code in our plain view, a priori, is awaiting revelation of the underlying real meaning, understanding, knowledge, and applications.

Some of the mathematical and physical entities given above are unreal, irrational, or imaginary. In theoretical physics, the terminology includes antimatter, dark matter, dark energy, black holes, Hawking radiation, quantum fields, John Wheeler's holographic illusion, and James Kowall's holographic screen of consciousness, among others. It is of interest to note that in sensible real-world biological MAL theoretical analysis, leads to the “negative doses”, which are unreal, but lead to convergence to “1”, which in turn, points to the value of the “Median” or 0.5. (see later in
Figure 19). In addition, the dose-effect relation shows visible inputs (dose) and outputs (effect, fa), with an invisible unaffected fraction of fu, in which the fa/fu ratio shows 180 ° and 360 ° cyclable reciprocal rotation (see
Section 1.8.1 in
Figure 11).
Humans make and decide on terms, units, definitions, and measurements in our surroundings, environment, world, galaxy, and universe, including units such as kilogram, meter, minute, volume, pressure, number, constant, index, grammar, rule/law, and ecosystem. While searching for knowledge and truth, we must realize that we are a tiny fraction of the universe. But do not forget to count ourselves in. We first need to solve real-world, day-to-day problems from a life perspective. Life and non-life, real and imaginary, are assessed from different angles and through different analyses, but all converge into only the supreme One, whatever the One is.
The most intriguing equation in mathematics: Euler’s Identity
It is a cornerstone of complex analysis and has widespread application in fields from mathematics to electrical engineering and quantum mechanics in the non-life domain. It is presented as
Euler’s identity,
In a mere seven symbols, it unites the base of the natural logarithm e, the imaginary unit i, the transcendental constant π, 1, and 0. One can be interpreted as the unity of full and partial distributions, and +1, 0, and -1 can be interpreted as One, nil, and imaginary, symmetrical non-existence counterpart of 1.

1.7.5. Human-Defined Units for Measurements for Sciences
Humans, as primates, decide Units — the basis of innate intuitive perception, intelligence, logic, and knowledge accumulation and exploration — which evolve into sciences.
Figure 9 gives the international SI units.
The different units may be multiplied or divided as required for the multiple or cross-disciplinary sciences.
The ratio of the same unit resulted in a dimensionless quantity, such as the Floating Ratio (fa/fu) and the Golden Ratio (In biology, fa/fu = (D/Dm)m (the median-effect equation), in physics, E/M = C2 (the relativity equation), in archeology, C14/C12 Ratio (of half-time) for age estimation. For the Unified General Theory to be dimensionless, it must be independent of physical state, size, structure, and complexity.
Mathematical manipulations of numbers and units can reveal intrinsic properties that confer a new meaning to identity and entity. These include x-y plot, x-y-x plot, double reciprocal plot (1/s vs. 1/vi, the Lineweaver-Burk plot for determining enzyme kinetic constants (Km for substrate and Ki for inhibitor), and deciding types of inhibition (competitive, non-competitive, and uncompetitive). MAL-MEE/CIE has extended this to a unified general utility theory of R&D.
1.7.6. Inductive and Deductive vs. Bottom-Up and Top-Down
The MAL MEE/DOM/UTO Unified Theory: A conceptual departure from the traditional observation-based R&D dominance
Given the complexity, variability, and diversity of universal events, observation, measurement, experimentation, and trial-and-error-based conclusions are unavoidable until a unified general principle of science and technology is available. The ancient traditional Chinese medicine. Sky constellations, religions, and arts are the manifestations.
Throughout history, whether among philosophers (e.g., Aristotle) and scientists (e.g., Einstein) or in science textbooks, there have been debates about induction and deduction, as recently described by David Kyle Johnson [
74]. Based on the context and semantics, Johnson indicated that deductive arguments are those with premises that guarantee their conclusion, while inductive arguments are those with premises that raise their conclusion’s probability, and concluded that deduction is reasoning that guarantees its conclusion; induction is reasoning that provides conclusions with probable support.
Thus, let us consider a scientist running an experiment to test a hypothesis; they will consider an experimental result that the hypothesis predicted as evidence for the hypothesis. (If H then R. R. Thus H.) Clearly, this follows the same pattern — yet we would not consider this form of reasoning deductive. Indeed, the good scientist will know and admit that the experimental result doesn’t prove the hypothesis true — it merely supports it or raises its probability. So, this is an example of inductive reasoning. And we wouldn’t consider it “fallacious.” If the experiment is conducted correctly, it could provide strong support for the hypothesis. So, whether an argument is deductive or inductive can be sensitive to context too; it depends on the intentions of the person giving it.
In recent years, Chou has compared the
Bottom-Up and Top-Down approaches to scientific R&D and concluded that, although they are opposite, they are mutually complementary, like two sides of the same coin [
19,
22,
24]. Interestingly, the terms Bottom, Up, Top, and Down, along with Charm and Strange, have already been used in Quarks in the standard elementary particle physics [
24,
75].
1.8. Life and Non-Life
There are two domains in the universe: Life and Non-Life, as manifested in the Floating Ratio and the Golden Ratio, as indicated in
Figure 10. Life domain dynamics are deterministic, finite, and cyclable. The non-life domain is open and infinite, and it involves complex numbers.
We need the distinction between Life and Non-Life in scientific R&D, dynamics, and informatics, as well as intelligence and artificial intelligence.
The transition from Life to Non-life is an abrupt paradigm shift that cannot exist in both forms, as described by Schrödinger’s cat. The transformation can be transcendental. In biology, it is live-or-dead; in pharmacology, it is all-or-none; in mass-action law, both Dm and m become zero; in philosophy, it is something to nothing; in religion, it is life to afterlife, or world to heaven; in physics, entropy becomes zero; and in mathematics, 1 becomes 0.

1.8.1. Visible and Invisible
MAL-MEE, fa/fu = (D/Dm)m, Manifests Life. However, the extrinsic properties we can sense or see, the intrinsic properties, or the underlying principle, are not necessarily visible. These functional dynamics are common to living systems, which involve receptor intermediates and transition steps within networks or pathways. We observe the inputs and outputs, but not the intermediate steps, except when the processes are slow or slowed by drastically lowering the temperature, and when they perform high-accuracy, fast measurements.
In the unified general median-effect equation, MAL-MEE, the floating ratio Fa/fu, where Fa is visible, and Fu is not visible, is subjected to the reciprocal and double-reciprocal, thus, recyclable, as described in
Figure 11.
Figure 11.
The MAL-MEE on the right is the dose of Maas (normalized by the median) for Inputs ↓; on the left of MEE is the causal Effect, fa, (expressed as the Floating Ratio (fa/fu) for outputs ↑. Both inputs and outputs are visible or sensible. However, the intermediary complexity of intermediates is not visible.
Figure 11.
The MAL-MEE on the right is the dose of Maas (normalized by the median) for Inputs ↓; on the left of MEE is the causal Effect, fa, (expressed as the Floating Ratio (fa/fu) for outputs ↑. Both inputs and outputs are visible or sensible. However, the intermediary complexity of intermediates is not visible.
1.8.2. The FR (fa/fu) Manifests Life Domain
For the MAL-MEE is, fa/fu = (D/Dm)m where fa + fu = 1.
On the left, fa and fu are fractions (affected and unaffected); their ratio, fa/fu, is dimensionless.
On the right, D and Dm have the same unit; the ratio cancels out any unit.
The MAL-MEE embedded invisible mathematical intrinsic properties:
where D is dose, fa is fraction affected, fu = 1 – fa, Dm is median-effect dose, and m is the dynamic order.
Single reciprocal and double reciprocal represent (180° and 360°), indicating a closed circular/recyclable system.
1.8.3. The Relativity Concept in Biology and Physics
The MAL-MEE can be rearranged as dose and effect: D = Dm [ fa/(1-fa) ]
1/m and
i.e., M = D/Dm (the Median normalized dose of Mass)
MAL expresses as the fractional distribution of One. The MAL-MEE causal relationship indicates a Floating Ratio (FR), (fa/fu):
(FR) = fa/fu = fa/(1 – fa) = (1 – fu)/ fu = (fu)-1 -1 = [(fa)-1 – 1] -1 = [D/Dm]m , which can be rearranged into
Since fa + fu =1, therefore, fa, the activation function in MAL, must be fa <1 (and fu <1) in the life
The MEE signifies the shape of
hyperbolic (m=1) and
sigmoidal (m>1, m<1) activation functions, as indicated in pharmacodynamics/bio-dynamics (PD/BD) derived from mathematics [
9,
11,
24], as well as those used in AI graphics as indicated by the Hopfield equation algorithm and graphics [
76,
77], derived from physics and engineering for the neural network [
78].
The Floating Ratio (FR = fa/fu) of the Median–Effect Equation (MEE) of the Mass-Action Law (MAL) manifests the Life domain. MAL-MEE defines the dynamic relationship between the mass entity of the dose (Inputs) and the functionality of the effect (Outputs) in a finite system.
The MEE took ten years to derive (1966-1976) [
1,
2,
3,
4] with a unique sequential, pattern, combinatorial general system analysis that involved over 300 reaction rate equations:
The Median Effect Plot (MEP) in double logarithmic form for x- and y-axis: log FR = log (fa/fu) = log (D) – m log (Dm), which determines Dm (dynamic potency, x-intercept), m (dynamic order, shape and slope for linearization (y = mx + b) of dose-effect curve, DEC) [
4,
9,
11,
24].
In MAL-MEE and MEP, FR is a dimensionless-relativity ratio (fa/fu = fa/(1-fa) regardless of unit, physical state, size, structure, and mechanistic complexity. Therefore, the MAL dynamic principle has universal applicability in Life science and beyond [
24], as evidenced by garnering 35,000 citations in 1,587 scientific journals and 1,597 patents worldwide, indicating its impact in R&D [
56,
57].
The D/Dm term is the dimensionless relativity ratio of the same kind, at any dynamic order (m). Thus, MAL-MEE-dictated informatics is regardless of unit, physical state, size, structure, and mechanistic complexity. Therefore, the MAL-MEE theory/algorithm/method has unlimited applications. The ramification across disciplines, sub-disciplines, and sub-sub-disciplines has resulted in over 3,000 journals in the biomedical sciences alone, with no consensus among scientific societies, associations, and schools of thought. The greatest concerns of contemporary R&D are the limited theoretical basis and the lack of a scalable principle for extending to multiple-entity interactions and interdisciplinary linking for generality. Innovation is not a matter of talent, but a matter of how we relate to reality, step beyond the conventional surface, and perceive the patterns that organize it
The FR, fa/fu, single-reciprocal (180°), and double-reciprocal (360°) allow binary circular and recyclable closed form, typically manifested in Life. However, MAL also reams Non-Life, as indicated in inter- and cross-disciplinary analysis.
1.8.4. Symmetry, Equilibrium, and Harmony
Comparing the Mathematical Sigmoidal Function and its Derivative with MAL-MEE
Philosophers, researchers, and scientists have observed the shape of dose-effect curves since ancient times. The most common shapes in pharmacology are sigmoidal curves, while in enzymology, simple enzyme molecules display hyperbolic curves. As A.V. Hill discovered, oxygen-hemoglobin interactions follow highly significant sigmoidal curves, leading to the Hill equation (1913), which molecular biology confirmed by showing that hemoglobin has four subunits that bind oxygen molecules cooperatively. In biochemistry, enzymologists also discover allosteric enzymes that contain subunits. In pharmacology and physiology, most often…
In
Figure 12, the MAL-Median-effect equation, fa/fu = (D/Dm)
m, a sigmoidal function, has been correlated with its derivatives [
79]. The graphics show perfect symmetry. Additional illustrations of MAL-MEE median-dose-based symmetry and equilibrium are given in
Figure 2,

Figure 35.

MAL-MEE activation function (fa) indicates a sigmoidal dose-effect curve (DEC) with its derivative showing a symmetrical distribution curve peaks at the Dm, where fa = fu = ½ (The Median point is 0.5), and its intrinsic property of symmetry.

1.9. Deterministic vs. Statistic: The Basic Math Forms
1.9.1. MAL-MEE-based Deterministic R&D
Transformations of MAL- MEE give:
Thus, , and .
Scalability:
Dose, D: Mass, Entity, Input (↓), Causal Effector, Activator, Inhibitor, Regulator, …;
Effect, fa: Response, or output (↑) via target receptor, for intermediate, pathway, network of mechanisms or metabolism, processing, and output decision…;
Unaffected fraction, fu: Invisible, insensible, imaginary, (1-fa), finite negative complementary effect (<1, > 0 and can be a fraction of the digital, where fa + fu =1, where fa/fu is the Floating Ratio (defined as FR), the floating dark material-like, negativity balancing effect, which is mediated by the MAL, FR = (D/Dm)m ;
Median, Dm: Universal reference of potency, or efficacy; harmonic mean, 2ab/(a + b), of kinetic constants Kii and Kis, and the causal mechanistic reference standard for homeostasis, symmetry, rhythm, balancing in actions and interaction, activation or inhibition, regulation, and feedback.
The Kii and Kis are the Ki values determined by the intercept and slope of the Lineweaver-Burk Plot, respectively. It was discovered [
3] that Dm (or I50) = 2 (Kii Kis)/(Kii + Kis) for the median dose, where fa = fu = 1/2 = 0.5.
Exponential “m” is the dynamic order signifying the shape of causal response graphic curve, where m =1 indicates hyperbolic activating or inhibitory function, and m ≠ 1 indicates a steep sigmoidal activation function, if m >1, steep sigmoidal; if m <1, it indicates a flat sigmoidal activation function. Therefore, the geometric function of MAL-MEE/CIE/DOM is identical to the tanh sigmoidal function in mathematics, and the Hopfield neural network activation function for artificial intelligence (AI), except that the theory and algorithm of MAL-theory is developed from life science.
1.9.2. Statistical, Probit Function and the Logistic Growth Function
Involving “ “
In pharmacology, statistical approaches such as Logit and PROBIT have been introduced (see
Table 2). The key ingredient is the logistic function, where an input is converted into a probability, written in the form:
Probability = ,
Logit of fa = [1/[1 + e-(α+β log D) ],
PROBIT function for fa is
The distinguishing feature of MAL-theory is that it is deterministically easy to use, and the algorithm is simple to program in digital data science, with automated simulations that yield quantitative or index-based conclusions in real-world problem-solving.
Clearly, fa and fu functionality, where fa + fu =1, is identical in mathematical and statistical forms of:
1.9.3. Fermi-Dirac Distributional Function of One with “e” Notation
MAL-MEE/DOM is essentially a
Fermi-Dirac distribution form (in statistical physics, the occupancy of energy states by fermions follows:
which is a sigmoidal function compared with the mass-action law MEE/DOM, as shown above in
Figure 7.
This mathematical form also appears in ecology as the logistic growth model for populations.
However, the biomedical, as well as the physical, engineering, and mathematical digital sciences, have used different symbols and designations without an “e” involvement.
1.9.4. Hopfield Neural Network function without “e” notation
The Hopfield neural network sigmoidal function of the basal algorithm of the sigmoidal activation function in artificial intelligence (
AI) [
76,
77,
78], in the form of the sigmoidal function.
Clearly, the fa and fu functionality of the mass-action law, where fa + fu =1, is identical in mathematical forms of the distribution function on “One”, for the Hopfield’s neural function: Fermi-Dirac distribution functions
It is of interest to note that the Mass-action law-based derived median-effect equation [
3,
4,
5,
6,
7] has the same form as the Hopfield’s neural network function, which does not involve the “e” functions, which is a conceptual breakthrough, and a paradigm shift in scientific research and development (R&D).
1.9.5. The MAL-MEE/DOM/CIE/UTO Causal-Effect Theory without the “e” Notation for the Real-World Phenomena
The following MAL-based biochemical/biological quantitative data sciences do not involve “e.” Most MAL equations have a typical mathematical form of a finite distribution function for “1”:
Fa = 1 / [1+ (Fractional distribution in ratio)m], where m =1 is the first-order dynamics (the Michaelis-Menten hyperbolic function), m < 1 for negative cooperativity with a flat sigmoidal function, and m>1 for positive cooperativity with a sigmoidal function
As indicated by comparing the MAL-MEE dynamics of Floating Ratio, FR (Manifesting Life), and the Golden Ratio, GR (Manifesting Non-Life) in
Table 3, the fundamental mathematical forms for Life and Non-life are exceedingly simple. The fundamental source codes:
for Life is a/b = a/(1- a) = (1 -b)/b, a + b =1; Expressed as fa/fu = (D/Dm)m
for Non-life is a/b = (a + b)/a = 1 + b/a; Expressed as [ = 1.618033…= (1 + √5)/2.
Both (a/b) ratios are expressions of the fractional distribution of “One” with basically different dynamic properties, yet maintaining a connection to “1”. For life is finite and cyclable distribution of ”1”; In Life, FR partitions 1 into complementary components (fa and fu, > 0, < 1, centered at the median, 0.5); In Non-Life, GR partitions 1 into continuous recursive sequences, extendable without a bound.

Where ki is the inhibition constant, I50 is Dm, Et is the total enzyme, and Ex is the portion of the enzyme that is occupied. This relationship is regardless of whether the inhibition is competitive, non-competitive, or uncompetitive (i.e., all types of inhibition).
This equation also indicates that Ki will never exceed I50.
This equation can be used to calculate fractional receptor binding or to estimate Ki from the experimentally determined IC50 value in first-order kinetics derivations [

where fi is the fraction inhibited, and fv is the uninhibited “control”. Therefore,
Table 4,

In biochemistry or molecular biology, fi and fv are equivalent to fa and fu in pharmacology or physiology (see Appendix I).

In this case, if the enzyme receptor has two substrates (A and B) and the inhibitor (I) as a reference ligand, the relationship based on the mass-action law is the following, where Ki/I
50 is the fractional occupancy of the enzyme binding site ( for
Space), whereas A/Ka and B/K
b is the normalized specific concentration (Mass) of A and B, respectively [

Note that I
50 is the median dose (Dm) in the first-order dynamics (m = 1) for the median effect equation for the 1
st-order effector kinetics/dynamics. (
Table 3A).
Km is the substrate kinetic constant (Ka, Kb). Ki is the inhibition constant, whereas Kii and Kis are the Ki values calculated based on the Lineweaver-Burk plot’s, x-intercept and slope, respectively.
In the median effect equation, fi/fv or fa/fu = [D/Dm]
m, the ratio of fractional inhibition in the presence or absence of any inhibitor, all kinetic constants (Km and Ki) cancel out, leaving only the dose-effect dynamic relationship [

Table 9 indicates a pattern of 1 plus a typical distribution function based on the mechanistic sequence of input and output patterns.
The reciprocal situations are illustrated in
Table 4,
Table 5 and
Table 6, with ki/I50 = Ex/Et, where Ex/Et = 1/[1 + (distribution function)]. Therefore, by definition, the whole enzyme (Et) represents “One”, and the MAL functional dynamics principle follows the same mathematical pattern of hyperbolic activation functions. This MAL-life-science-based pattern is identical to the geometric, physical, and AI-algorithm patterns, as Appendix III shows.

6] and from first-order dynamics to m
th-order dynamics [
7]. These led to the discovery of the unified general theory of median-effect equation (MEE) [
4], the combination index equation (CIE) [

The above efforts led to a period of conceptual consolidation and integration of MAL theory and method [

24], as well as to interdisciplinary collaborations, including drug discoveries and free software downloads.
After retirement in 2013, the theoretical work on MAL-MEE/CIE/DOM continue, and introduced the UTO, top-down vs. bottom-up complementary concepts in scientific R&D [

Typical math tools include ratios, reciprocals for 180°, images, double-reciprocals for 360°, circles, logarithms, and double logarithms for the x- and y-axes. Then, look for intrinsic properties, the general principle, and the unified theory.
Categorizing and Generalization, Mathematical Induction and Deduction
1.10.1. Linearization of Inhibitor Curves of Different Types with the Double Reciprocal Plot
Log (D or I) vs. Log Fractional Effect Ratio; log FR: log [(fa)-1 -1]-1 is the double logarithmic plot that reveals the hidden informatics from the dose-effect dynamics measurements,
Figure 13.
This double-logarithmic principle for first-order dynamics is a precursor to higher-order dynamics [
4,
5,
6,
7], which are described by the median-effect equation (MEE) and the median-effect plot (MEP) [
4,

The double logarithmic plot of [log (I/ki or Ex/Et )or I/Ki) vs. log Fa/fv is the fractional occupancy of the enzyme targeted, where Et is the total amount of enzyme target, and Ex is the amount of enzyme occupied [
5].
The discovery was: Ex/Et = Ki/IC50. This later leads to the Median-effect equation (MEE), fa/fu = [D/Dm]m. It is the distribution function of One. Thus, logarithmic transformation and double reciprocals mathematically diagnose the type of inhibition interaction. The enzyme as a whole entity is represented as “one”. The rest are fractional distribution functions.
For scale-up applications, during 1984-2024, the MAL theory scientific terminologies have been updated, as shown below:
x-axis is the log of [ki normalized inhibitor Dose concentration]
y-axis is a log of the Floating Ratio (FR),
fi is the fraction affected (fa)
fv is the fraction unaffected (fu)
fi/fv = [(fv)-1 -1] = [(fi)-1 - 1]-1, or fa/fu is named the Floating Ratio (FR), in which MAL-MEE indicates that FR is a Double Reciprocal Function in life sciences.
Appendix I gives he details of the evolution in symbols, abbreviations, and definitions.
1.10.2. The Double-Reciprocal Plot (The Lineweaver-Burk Plot for the 1/S vs. 1/v) Linearize the Dose-Effect Curves for 1/I vs 1/fi, Regardless of the Type of the Inhibitory Effect of Inhibitors
Mathematically, a single reciprocal is a 180 ° rotation, and a double reciprocal is a 360 ° rotation (one circle), as indicated in the Floating Ratio (FR) in the median-effect equation (MEE) of the mass-action law (MAL). Thus, the double-reciprocal plot reveals hidden information from dose-effect dynamics measurements.
Both the x- and y-axes are single reciprocal transformations that generate kinetic/dynamic constants and diagnose the types of inhibition. (
Figure 14).
Figure 14.
The reciprocal of inhibitor concentration and the reciprocal of fractional inhibition in one-substrate reactions. Thus, under the umbrella of the mass-action law, the inhibitor (I) and substrate (S) are equivalent in terms of entity-mass; i.e., the double-reciprocal plot for (I) is equivalent to the Lineweaver-Burk plot for the saturation relationship.
Figure 14.

Thus, under the umbrella of the mass-action law, the inhibitor (I) and substrate (S) are equivalent in terms of entity-mass; i.e., the double-reciprocal plot for (I) is equivalent to the Lineweaver-Burk plot for the saturation relationship.
Thus, a plot of log [(f
i)
-1 - 1]
-1 on the ordinate, against log (I/K
i) on the abscissa, is linear with a slope of unity. The slope of one is a consequence of the first-order (i.e., univalent) interaction. The intercept on the ordinate gives log (E
x/E
t) or log (K
i/I
50), regardless of the enzyme reaction mechanism or the inhibition mechanism. For the single-substrate reaction [
9]. Therefore, for competitive, non-competitive, and uncompetitive inhibitions, respectively, are [

24], as highlighted in
Figure 13,

A double reciprocal plot for inhibitor concentration and fractional effect. Different types of inhibitory mechanisms show the same linearity and intercept at 1 (One). The inhibitor or multiple inhibitors are the “reference ligands.” This is another reason that MAL-MEE is the Grand General Theory for the later Unity Theory of One (UTO), where MAL-MEE, CIE, and DRIE are all based on the standard of “One” as the universal standard [
9,
11,
24].
1.10.3. The Normalized Doses as a Function of the Reciprocal of the Fractional Distribution Function (I50/Ki)
In this regard,
Figure 15 also follows the principle of the double-reciprocal plot, which translates dynamic studies into digital informatics conclusions.
Figure 15.
The MAL-based unity theory of one (UTO) and fractional distribution of effect (i.e., the fractional binding (occupancy) of the receptor for actions[

50 or Ex/Et), part vs. the whole.

This confirms the unity of one (UTO) theory. All lines intersect at 1 (One) on the y-axis (

1.11.“. Space” Concept in MAL-MEE Unified Theory
Exclusiveness and Non-Exclusiveness Determination
Exclusivity is beyond competitiveness (e.g., competitive, non-competitive, and uncompetitive inhibition, as determined by the Lineweaver-Burk plot). Exclusive and non-exclusive inhibition is directly relevant to the ”space” concept as introduced by Chou-Talalay in 1981 [
7], and further discussed in 1991 [
23].
1.11.1. Mutually Exclusive and Non-Exclusive Types of Binding to the Receptor Between Two Inhibitors
The dose-effect curves in
Figure 16A and 17A are all linearized by the MEP double-reciprocal plot (
Figure 16B and 17B) in mutually exclusive cases (curves a, b, and c). However, the mutually non-exclusive curve (d) cannot be linearized. This is the first time the space-exclusivity concept has been introduced quantitatively in the life sciences. They may be applied to AI algorithms or other areas of data science. This is a powerful demonstration of the MEP double-logarithmic plot concept.

In this case, the mass-action law's exclusivity concerns space and mass, not time and force. The Dm and m parameters jointly provide ID for any dynamic entity under consideration. For multiple inhibitors (or the reference ligands),
1.11.2. Equations of Multiple Entities Exclusivity in Combinations
For a mutually exclusive (normal) condition, the two-entity combination’s CI equations is:
For two drugs, and for n-drugs.
Whereas for a mutually non-exclusive condition, the two-entity Combination’s CI equation is:
The CI equation for the non-exclusive two-drug or inhibitor combinations has additional terms, (D)1(D)2/ (Dx)1(Dx)2, compared with the CI equation for the mutually exclusive case in combinations. Thus, the non-exclusive case will yield a slightly larger CI value (than the exclusive case), implying less synergism estimation, since the definition of synergism is CI <1 [
7,
8,
27]. However, the mutual non-exclusiveness among mass entities in reference ligands (such as different types of inhibitors)
1.11.3. The MAL Dynamic Space Concept and the Time-space in Quantum Physics
The above MAL-dynamics, mutually exclusive and non-exclusive concept in biology (
Figure 16 and
Figure 17), has a surprising similarity in graphic form to the time-space concept in quantum physics. However, they intuitively seem hard to connect.
In a recent article by a physician-theoretical physicist, James Kowall [
108,
109], on how the holographic principle unifies gravity with quantum theory and solves the measurement problem of quantum theory and the hard problem of consciousness, which exhibits a graph on the accelerating observers' event horizon in the time-space coordinates (
Figure 18). It compares (i) the accelerating observer’s world line, (ii) her own horizon, and (iii) a light ray that never catches up with her as long as she accelerates. Interestingly, her worldline (i) departs from the smooth course, and crosses over with (ii and iii) if she stops accelerating.
Similar scenarios occur in
Figure 16B and 17B, where c lines are for mutually exclusive, and d curves are for mutually non-exclusive cases, which are related to the “space” and “dose-effect relationship” of two entities (I
1 and I
2).
Figure 18.
Comparison of the holographic screen when the observer is accelerating and stops accelerating in quantum theory.

Comparison of the holographic screen when the observer is accelerating and stops accelerating in quantum theory.
Kowall noted that it’s worth understanding how Hawking performed his calculation. The first thing he had to calculate was the temperature of the event horizon [
108]. This idea goes back to the Unruh temperature, which is defined for any accelerating observer. An accelerating observer always has its own event horizon that limits the observer’s observations of things in space. The observer can observe nothing beyond the limits of its event horizon due to the constancy of the speed of light. This limitation of observation is always from the point of view of the observer. In the generic case of an accelerating observer following an accelerating world line through some space-time geometry, this is called a Rindler event horizon.
The accelerating observer’s event horizon has a temperature known as the Unruh temperature. This is a very general result of quantum theory. In terms of the observer’s own acceleration, which is called a, the Unruh temperature is given as kT=ħa/2πc. [
108].

1.12. Halt-Center Geometry: Comparing Life Dynamics with Mathematical and Physical Mass, Force, Time, and Space
MAL Median of Life Science vs. Half Time of Radiation
Mass and Force are theoretically exchangeable based on Einstein’s relativity. The relationship between space and Time is currently a hot topic of discussion, as indicated in Appendix III. Mass and time do not usually interchange. However, Dm and T
1/2 curves show intriguing similarity, as shown in
Figure 20. The slight difference in curvature is due to MAL in Life science showing intermediate transitions between simple and complex variables in Mass for activities (Dm value) and for different dynamic orders (m value) over time. In contrast, radiation decay is not mediated by a complicated intermediate during the time course. The elements of the universe, Life, Mass, Force, Time, and Space, are individually sensible and measurable; however, they are interlinked or cross-linked among them in unity for size, length, volume, vectoral angle, and speed, except for inertia or at zero dose, zero movement.

The radiation decay curve in a unit of (blue line).
The unaffected fraction (Fu) is based on MAL in the unit of Dm (in red line). The difference between the two curves at the fundamental level stems from the fact that biological systems, to perform complex dynamic functions, involve a causal-effect relationship between “receptors” that lead to intermediate complexes, which may involve networks or pathways. For example, oxygen-hemoglobin interactions involve hemoglobin's four subunits; each step of the interaction exhibits cooperativity, yielding a sigmoidal saturation curve. Most drugs, neurotransmitters, and hormones have specific receptors. Physical steps may also involve a simpler affinity receptor, such as that described by Langmuir’s Adsorption Isotherm on the surface.

24], when
, m = 2. Note that the two curves are similar and cross-over at

Fu is slightly lower (i.e., more affected), and post-cross-over, Fu is slightly higher (i.e., less affected). This figure compares biology and physics, as well as mass and time. Physics is rigid, and biology is more flexible but follows the principle of MAL. This comparison is independent of the units or physical states of mass, or of the type or energy level of the radiation.
1.12.2. The Median and the Harmonic Ancient Philosophy
The median-effect equation (MEE of MAL or the DOM) indicates that Dose and Effect are interchangeable.

24] is the universal reference point in dynamics, and the dynamic order’s common link.

Theoretical analysis indicates that the Isobologram (dose-oriented) and the Fa-CI plot (effect-oriented) yield identical interaction indices (CI values). They are like two sides of the same coin. Source, or two views from two different angular loci of space.
1.12.3. Riemann’s Zeta Function’s ½ Critical Line and the MAL’s Median
The Riemann Hypothesis has stood as mathematics’ Everest — beautiful, imposing, unconquered. It claims that all non-trivial zeros of the zeta function have real part 1/2. What makes 1/2 so special is that the universe’s prime number distribution obeys it with such precision.
The Riemann zeta function appears simple: ζ(s) = 1 + 1/2^s + 1/3^s + 1/4^s + ...,
The term nontrivial zero comes from the Riemann zeta function [
110,
111]
which is the sum of the reciprocals of the squared-number-series as indicated in the 2
o (squared) Pascal Triangle [
1,
2] derived from the biological inputs-outputs duplex patterns transition combinatorial analysis in Chou TC’s Ph.D. Thesis, Yale University, 1970. The Riemann Zeta Function can be expressed in the following different forms:
But look closer through our three-domain lens [
80]:
Counting Domain: The sum over reciprocal integers of (1, 2, 3, …)
Measuring Domain: The continuous exponentials
Manipulation Domain: The operation n^(-s) that bridges them
The zeta function is literally a
domain-bridging operator that connects counting to measuring via manipulation, that transforms the boundary between natural numbers to an irrational entity (
For the nontribal zeros lie in the critical strip: 0 <
ypothsis shows that every nontrivial zero lies on the critical line at
=1/2. Half is the critical line as the balance point (medium) because it’s the only line where all three domains have equal voice. Only at 1/2 do the forces balance for the complex number s = ½ + it that satisfies + as described by ζ(s) = 0, located inside the critical strip. Such zeros encode the information that has been shown to reveal the distribution of prime numbers, symmetry in number theory, and spectral properties of physical and quantum systems [
80,
81]. Interestingly, the core concept of MAL-MEE, fa/fu = (D/Dm)
m, of derived life science [
3,
4], emphasizes the “Median” or ½ or “0.5” in the MAL-median effect principle, Doctrine of the Median (DOM), and in CIE and DRIE.
Both the MAL median principle and the Riemann zeta function share intriguing properties and analogies, which are listed in

1.12.4. Imaginary “Negative Doses” Converge at “One” on the “Median”
As shown in
Figure 21, where the dose (D) is [I], Dm is I
50, and Unity is One. The real doses can be projected to the surreal doses (i.e., the negative doses).
In biology, the Median-Effective Dose (Dm) is represented by I50, ED50, TD50, and LD50, respectively, as the dose that produces a 50% effect (inhibition, toxicity, or lethality).
Decades later, this led to the Doctrine of the Median (DOM) and the Unity Theory of One (UTO) as the unified general theory of the Mass-Action Law (MAL). As indicated by MAL-MEE (at m=1), the hyperbolic function is the same as the activation function that can be used in AI as the basic hyperbolic function. Whereas when >1 and <I, it is the activation of sigmoidal functional layers.
It is of interest to determine whether the negative dose, as shown in
Figure 21 from theoretical biology, is related to dark matter, dark energy, antimatter, and black holes in theoretical physics. The like linkage will be via mathematics.

Again, using “I” as the reference ligand as the “effector” that produces the effect. It shows the “unity” concept of the “median dose” of IC50 (or Dm). The real inhibitor doses and
the imaginative negative doses (-[I], intercept at “One” (1.0), which points to the “Median” (I
50). (
Figure 21).
The corresponding real dose and unreal dose converge into unity of “One” at the “Median” (I
50) [
5].

MAL Revelations at the Molecular and Conceptual Level
1.13.1. The Median Dose (Dm or I50) is the Unit of the Normalized Dose
Figure 22 shows the dose-effect relationship when the inhibitor serves as the reference ligand in the substrate-product enzyme system. The inhibitor dose (I) can be normalized to the median dose (I
50). Kinetic studies indicate that [I] is the inhibitor dose, and fi is the fraction affected (fa); when fi = 0.5, it indicates the median (Dm).
Figure 22.
The geometric property of effector dose [I] vs. fractional inhibition (fi) when the dose is in the unit of the median effect dose (I50). The “Dose“ can be transformed as the “Median-dose Unit” (normalization) to become a dimensionless ratio due to the ratio-cancellation principle (I/I50 or D/Dm).

Using inhibitor concentration [I] as the reference ligand, for the target (e.g., enzyme), the intriguing relationship of the dose [I] and its median-dose (Dm or IC
50 ) leads to the median-effect principle (MEP) and the doctrine of the Median (DOM) of the Mass-action Law (MAL) (

Note that on the left, regardless of the types of inhibition, the lines converge at “one”. On the right, the common median point and the median-axis for competitive and uncompetitive inhibition are shown in a symmetrical fashion. In contrast, for noncompetitive inhibition, it remains at One, since the receptor enzyme (Et) is generally fully occupied (i.e., Ex = Et), where Ki/I
50 = Ex/Et. The general equations for fractional velocity (fv) and fractional inhibition (fi) in the presence of an inhibitor (
I) can be expressed by fv = 1/[1 + (I/Ki) [Ex/Et]] and fi = 1/[1 + (Ki/I) (Et/Ex)], [
3]. Note that I is a dose (D), and I
50 is the median-effect dose (Dm); fi is the fraction affected, and fv is the fraction unaffected, and fi + fv =1.
In the physical domain of Nature, there are unique features of symmetry of patterns. Fractal is not like the Golden Ratio, nor like a mirror image, but just eerily repeating patterns that can be magnified or shrunk into the same size as described in dictionaries. Frank Ramsey’s symmetry on the circular edge, basically a bunch of points (called vertices), that generate a wonder of graphics, as recently described by Ben Fairbairn [
82]. These perfect patterns are unlikely to occur in the life sciences.
4. Unified General Mass-Action Law Doctrine of the Median as the General Principle: Convergence and Emergence
The unified general theory requires general system analysis without setting preconditions or specific arbitrage models. The mass-action law (MAL) is Nature’s fundamental physical and chemical principle, rather than an arbitrary selection on “Model”. In new drug developments, many use PK models without using the MAL-based PD principle.
Numerous unified, general, universal theories have been proposed earlier, including the theory of relativity, string theory, the Big Bang theory, the fundamental density theory, and many others. All of them have their theoretical basis, in one way or another.
One major criterion is applicability, scalability, and flexibility. The MAL-unified general theory/equations and algorithms are inching toward inter- and cross-disciplinary applicability, although they are not expected to be exhausted.
The MAL unity theory stays as is. However, the better ideas shall not be excluded.
Other Multi- and Cross-Disciplinary Convergence to the MAL
No unified general theories can exhaustively cover everything; the MAL-MEE/DOM/MTDPT/CIE DRIE for the Unity Theory of One (UTO) and Life-Centric Universe (LCU) have no exception. Humans are prone to errors, especially when making many unique statements and using unfamiliar terminology. I expect not all scientists will agree with my personal points here. I would welcome any individual who independently puts forward a better idea or thought. The MAL-theory/equations/algorithms have undergone scrutiny for over 5 decades.
4.1. Conceptual Transformations: Double Reciprocal, Double Logarithmic, Floating Ratio, and the Median-normalized Mass
The Mass-Action Law (MAL) algorithm-based paradigm has been proposed by this author, aiming to unify the analysis of dynamic processes across the life sciences, chemical, and physical sciences. The core concept is the Unity Theory of One (UTO), which describes natural phenomena as fractions of a unified whole (“One”) that can bridge the two domains of Nature: life and non-life. This framework introduces the Doctrine of the Median (DOM) – the idea that the median point of any dose-effect relationship is a universal reference – and posits a life-centric view of the universe, placing “Life” conceptually at the center among the fundamental elements of mass, force, time, and space. In this overview, we explain the key components of Chou’s paradigm (the MAL equations and their algorithms), assess its interdisciplinary significance, and illustrate the concepts with diagrams and examples. The tone is explanatory, geared toward scientists and policy makers interested in cross-disciplinary innovation.
4.2. MAL-Based Median and Doctrine of Median
The framework builds on the classical Mass-Action Law (MAL), a principle from chemistry/biochemistry that governs how entities interact (e.g., drug molecules with targets). Through MAL-based system analysis of input-output patterns, Chou derived a
unified dose-effect relationship, known as the
median-effect equation (MEE) [
4]. The MEE is expressed as:
where
D is the dose (or generally, the amount of any stimulus),
Dm is the median-effect dose (the dose that produces a 50% effect),
fa is the fraction affected (e.g. the proportion of a system that responds),
fu is the fraction unaffected (so
), and
m is an exponent called the dynamic order [
9,
11]. This simple formula implies that the ratio of “affected” to “unaffected” is related to the dose in a power-law manner. Crucially, when
, the dose
equals
by definition (the point where half the system is affected). Fa/fu is called the Floating Ratio (FR). The parameter
m governs the shape of the dose-response curve: if
, the relationship is a classical hyperbolic curve; if m is not equal to 1 (greater or smaller), the curve becomes sigmoidal (S-shaped) or flattened S-shaped. In other words,
yields a Michaelis-Menten-like simple saturation, while
or
produces steeper or shallower sigmoidal transitions (indicating higher or lower cooperativity in effect) [
9,
24].
The median-effect equation is remarkably general – it subsumes many classical biological and physical response models as special cases. In fact, it has been shown that the MEE unifies the equations for enzyme kinetics (Michaelis–Menten), receptor binding (Hill and Scatchard equations), pH ionization (Henderson–Hasselbalch equation), and more, by interpreting their “half-effective” constants (e.g., Km, Kd, pK) as analogs of
. Thus,
“Dose” and “Effect” (or more abstractly, mass and function)
become interchangeable under this unified law. The Doctrine of the Median (DOM) holds that the median point (50% effect level) is a universal pivot for any effect dynamics. By plotting data as
vs. (called the
median-effect plot), one obtains a straight line whose slope = m and x-intercept =
. This means that with only a few data points, one can determine m and Dm and thereby define the entire dose-response curve, indeed, a surprising consequence – termed the
“Minimum Two-Data-Point Theory” (MTDPT) – is that if a system obeys the MAL median-effect principle, then two experimental data points (plus two default points at zero effect for zero dose, and 50% effect at Dm) can theoretically
describe the full dose-response [
9]. This defies the common notion that at least three points are needed to draw a curve and highlights the power of the MAL algorithm, which automatically includes 0% and 50% points as anchors [
9,
11]. In practice, having more points is prudent. Still, this principle underlies a
“top-down” approach to research: starting from a general law to guide minimal experiments, rather than the traditional “bottom-up” approach of many specific observations [
9,
10,
11,
12,
14,
15,
16,
17,
18,
19,
20,
21].
Because the MEE’s terms are
dimensionless ratios (fractions and normalized doses), the equation holds regardless of units, physical state, size, structure, or mechanistic details and Complexity [
9,
11,
23,
24]
. This gives it a universal character: whether one is measuring drug concentration in moles, radiation in Gray, or signal intensity in arbitrary units, the relationship
, where D/Dm is the median dose-normalized Mass, should hold if the process follows mass-action law dynamics [
9], thus, “Effect” and “Mass” are interchangeable or equivalent in biology. This is akin to Einstein’s theory of relativity,
E = MC2, which indicates that “Energy” and “Mass” are equivalent in physics. Chou emphasizes that this property makes the MAL framework a kind of “common language”, in which exponent m signifies dynamic-order, which also signifies the shape of dose-effect curves, i.e., m =1 denotes hyperbolic curve, m>1 gives sigmoidal curve, and m<1 gives flat-sigmoidal curve, for quantitative biology and beyond [
9,
11,
23,
24]. It also means that
potency (Dm) and
curve shape (m) are the key parameters for characterizing the effect of a single agent or a combination of multiple agents. These two parameters provide a complete digital description of the general dose-effect relationship, including its defined geometric properties[
9,
11]. The median,
in particular is a “universal reference point” that signifies an equilibrium or halfway state across diverse systems. Thanks to these features, the MAL median-effect method has very broad applicability. It has been applied not only in biomedical research (pharmacology, cancer therapy, toxicology) but also in fields such as environmental science, agriculture, and even marine biology, wherever dose-response or stimulus-response relationships arise [
18].
In summary, the Median-Effect Equation condenses centuries of dose-response knowledge into a single formula. It provides a conceptual paradigm shift by asserting that
all processes governed by mass-action law can be described by a single, unified equation, with differences limited to two parameters. This lays the groundwork for integrating data from multiple disciplines and for conducting research more efficiently. For scientists, it suggests that outcomes can be simulated or predicted with minimal input data. For policymakers, it promises more cost-effective, “Econo-Green” research designs that reduce experimental waste [
20,
21]. In practice, software inspired by this theory (e.g., CompuSyn) can use a few data points to run computer simulations, yielding an entire curve and related metrics in seconds, streamlining the R&D process [
22,
23].

However, in pharmacology and life sciences, the dose-effect relationship in combination follows the MAL-unified general combination index equation (CIE) theorem. In contrast, A and B are for Effect (force or energy), which requires Dose (mass or entity) and action or interaction rate, which involves time (change of mass condition per time, for speed). In physics, speed (distance/time) is squared, as indicated by Einstein’s relativity theory, E/M = C

4.4. MAL-Median Unified Theory Aligns with Major Historical Conclusions in Mathematics and Physics (see Section 1.12 and Section 8.9)
A recent review of MAL-MEE/Doctrine of the Median (DOM) leads to the Unity Theory of One (UTO), which uses "One" as a universal standard, and the Life-Centric Universe (LCU), which positions Life among Mass, Force, Time, and Space to promote humanism over materialism. New conclusions include:
(1) The universe contains Life and Non-Life domains.
In Life, MAL-MEE's Floating Ratio (FR), fa/fu = fa/(1–fa) = (1–fu)/fu = (fu)-1-1 = [(fa)-1 -1]-1, forms a circular, closed, recyclable pattern; Non-Life domains (physics, mathematics, and AI) follow the Golden Ratio (GR), φ = 1 + 1/φ = (1 + √5)/2 = 1.618033…, an irrational open form extending to infinity. The Golden Ratio has been used or related broadly in geometry, the Fibonacci sequence, Lucas number, Penrose tiling, Kepler triangle, spiral galaxies, Golden Spiral, architectural designs, and plant floral patterns.
(2) FR has the fractional form a/b = a/(1–a) = (1 -b)/b, while GR has a/b = (a + b)/a = 1 + b/a.
(3) Both are fractional distribution functions of "1": FR finite, GR infinite.
(4) Rearranging MEE yields fa = 1/[1 + (Dm/D)m] and fu = 1/[1 + (D/Dm)m], forms analogous to probability distributions, Logit, PROBIT, and Fermi–Dirac functions, except those containing Euler's e, limiting real-world biomedical utility. Log is often more practical than the Natural Logarithm (Ln).
(5) While Michaelis–Menten, Hill, Henderson–Hasselbalch, Scatchard, Langmuir isotherm, and Hopfield activation functions for neural networks contain no “e”, they are model-specific and not broadly expandable.
(6) MAL-MEE’s Median = 0.5 parallels α = 1/2 in Alfaro’s Fundamental Density Theory and Re(s)=1/2 in the Riemann Zeta Function.
(7) Ratios define relativity, including GR, FR, C14/C12 (time), E/M = C² (Einstein), F/M = a (Newton), and Dm/t1/2 (MAL/physics).
(8) MAL-MEE provides algorithms illustrating competitiveness, exclusivity, symmetry, equilibrium, balance, homeostasis, cooperativity, feedback, visible input/output versus invisible intermediates, pathway, network, and harmony.
These findings indicate that the MAL-Median Unified Theory aligns with major historical conclusions in mathematics and physics.
The MAL-MEE-CIE-DRIE/DOM/UTO-Theory-based approach for general scientific R&D does not represent gradual progress, but rather a new framework that conforms to Nature’s laws and principles, constituting a paradigm shift in numerical digital science for this AI-assisted electronic automation era. Conceptually, the MAL-theory-based top-down R&D approach is opposite to the traditional observation-statistic-based.
