Abstract: Rotavirus A (RVA) is an important enteric pathogen of neonatal animals, whereas the genomic diversity of donkey-origin RVA remains incompletely defined. In 2025, an RVA strain was recovered from a diarrheic donkey foal in Shandong Province, China, and designated RVA/Donkey-wt/CHN/SD2503/2025/G3P[59] (SD2503). Viral RNA was subjected to Illumina NovaSeq paired-end sequencing, de novo assembly, genotype assignment, sequence comparison, and segment-specific maximum-likelihood phylogenetic analysis. All 11 genome segments were recovered, yielding the constellation G3-P[59]-I3-R3-C3-M3-A9-N3-T3-E3-H6. The VP4 gene was highly divergent: the closest BLASTn match was the P[24] rhesus strain TUCH, with 79.58% nucleotide identity, below the 80% threshold used to assign VP4 sequences to the same P genotype. The VP4 sequence was subsequently confirmed by the Rotavirus Classification Working Group as P[59]. Other segments showed discordant relationships. VP7 clustered with rabbit strain rab1404 with strong bootstrap support, whereas several internal genes grouped within genotype backgrounds represented by simian, rabbit, pangolin, equine, and other mammalian RVAs. The topological incongruence across segments, together with the unusual genotype constellation, is consistent with a complex reassortant evolutionary history involving cross-species-associated RVA lineages. SD2503 provides an 11-segment genomic framework for an independently identified donkey G3P[59] RVA and supports broader genomic surveillance of RVA in equids.

Abstract: Deep-learning models that predict aggregate fixation density from a media asset alone are now used as measurement instruments in advertising, packaging, interface, and educational research. The central validity question for this practice is domain transfer: whether a model trained on one distribution of stimuli, observers, tasks, and viewing contexts predicts fixations on the materials it is actually deployed on. This critical narrative review organizes the transfer problem into three progressively finer scales of stimulus shift—from natural scenes to designed media, between classes of designed media, and between categories within a class—and a cross-cutting axis of observers, tasks, contexts, and time, and finds the evidence sharply asymmetric: degradation from natural scenes to designed media is robustly documented; transfer between designed-media classes is supported by limited but consistent evidence; within-category and population-level transfer remain largely untested. I then reframe the practical response, specialization, as a finite-data pooling problem—complete pooling (one generalist), no pooling (independent specialists), and partial pooling (shared structure with category-specific adaptation)—and argue that partial pooling is the hypothesis most consistent with the evidence, not an established result. A company practice vignette, drawn from an unpublished internal development program, illustrates how the trade-off resolves operationally. I close with a pre-deployment transfer-testing protocol with predefined acceptance criteria and reporting items for studies that rely on predicted rather than measured gaze.

Abstract: Within the unified theoretical framework developed in the fundamental research by Anastasia N. Vikhareva, "Electromagnetic Structure of the Atomic Nucleus in 10D Space. Prosto, Proto, and Fon — Measurements" (DOI: 10.5281/zenodo.20965963), a continuous physical interconnection is established between the microstructure of elementary particles and the global density parameters of the Universe. Describing reality as a dynamic interface of continuous multidimensional phases completely eliminates the "vacuum catastrophe" paradox without relying on artificial quantum constraints. The derived mathematical apparatus proves that the fundamental constants of both the microcosm and macrocosm are rigidly conjugate through the geometric properties of the spatial solenoid.

Abstract: Digital mental health interventions increasingly use narrative, game design, personalisation and behavioural data to support engagement, but it remains unclear how these features can be integrated without weakening fidelity to the original evidence-based intervention approach. This study examined interdisciplinary perspectives on a narrative based serious game and meaningful engagement framework for preventative digital mental health grounded in Self Help Plus (SH+) and Acceptance and Commitment Therapy (ACT) informed principles. A two-round electronic Delphi (eDelphi) study was conducted involving participants from Human-Computer Interaction (HCI), mental health experts, and representatives of the target user groups. Fifteen participants completed Round 1 and following attrition, twelve completed Round 2. Consensus required at least 70% agreement or disagreement and an interquartile range of no more than 1. Round 1 assessed agreement with core framework assumptions and established consensus on 6/12 items. Round 2 re-rated the six unresolved items with controlled feedback, introduced five clarification items and elicited refinement priorities. Round 1 showed broad support for narrative, game design, behavioural observation, transferability and flexible pacing, but identified tensions around translation of SH+/ACT principles, oversimplification, narrative complexity, behavioural data sufficiency, context specificity and autonomy. Round 2 produced consensus that SH+/ACT principles can be translated into interactive mechanics when the core SH+/ACT content and processes remain stable and adaptation occurs mainly through delivery style, examples, pacing, narrative framing and interaction format. Participants also supported adjustable narrative depth, multidimensional engagement assessment, principle level transferability and guided autonomy. The framework received partial conceptual support, but findings indicate that further development should proceed through a modular minimum viable product (MVP) and empirical testing rather than immediate deployment.

Abstract: Hantavirus cardiopulmonary syndrome (HCPS) caused by Andes virus is a severe zoonotic disease characterized by a paradoxical cardiac phenotype: profound myocardial dysfunction that is frequently reversible in survivors and occurs without extensive structural damage. The mechanisms linking systemic inflammation to this reversible dysfunction remain unknown. This review examines the hypothesis that inflammatory signaling converges on the cardiac ryanodine receptor (RyR2), a major intracellular Ca²⁺-release channel, through post-translational modifications, generating reversible myocardial dysfunction in HCPS. In severe disease, elevated IL-6, reactive oxygen and nitrogen species, and nitrosative stress activate pathways that in experimental models converge on RyR2 through CaMKII-dependent phosphorylation at Ser2814, oxidative modification of cysteine residues, and S-nitrosylation, each destabilizing the channel and promoting diastolic Ca²⁺ leak. The resulting increase in spontaneous Ca²⁺ release reduces SR Ca²⁺ content, impairs contractility, and predisposes to arrhythmias. This framework identifies RyR2 as a plausible mechanistic hub for the reversible cardiac phenotype. Therapeutic implications are discussed, emphasizing the timing of interventions and the potential of rycals, drugs that stabilize the closed state of RyR2 and prevent diastolic Ca²⁺ leak, as an emerging strategy. This model provides a testable hypothesis for a disease that currently lacks specific treatment.

Abstract: Background: NOHARM scores a language model's management plan for a real primary-care-to-specialist consultation against specialists' ratings of the actions the case calls for. Most severe errors are omissions. The public leaderboard scores models on the bare case, with no instruction. Objective: To measure how much a structured instruction changes these scores, which part of the instruction matters, and whether the extra content is safe. Methods: On the 30 public cases (330 items), twelve models answered the bare case and five also answered with an instruction. An AI evaluator applied the benchmark's own scoring. On two models we tested the instruction's parts separately, against a plain request for 25 recommendations. Model raters and a physician reviewed the added actions the rubric does not cover. Intervals come from resampling whole cases. Results: The instruction raised severity-weighted F1 by 0.14 on average [0.09, 0.20], most for the tersest models: GPT-5.6 terra rose from 0.678 to 0.853 and Grok 4.7 from 0.354 to 0.633. The spread between models halved (standard deviation 0.17 to 0.09). Taken apart on Sonnet 5.5 and terra, the plan format alone matched the full instruction, while the request for 25 recommendations produced as many actions but scored lower (-0.040 [-0.069, -0.015] for Sonnet 5.5, -0.084 [-0.148, -0.029] for terra). Most recovered actions were follow-up and counselling. Instructed Sonnet proposed +0.13 [+0.05, +0.23] more specialist-rated harmful options per item, mostly mild or moderate; a physician reading them in context judged none harmful, and judged none of the 72 unlisted actions that a model rater had flagged as harmful to be inappropriate. One instructed call scored level with a four-call system (+0.004 [-0.035, +0.041]). The best configuration, three instructed models combined, scored 0.897 (0.869 under a second evaluator), above the benchmark's published public-case reference scores (best 0.720), though under a different evaluator and not comparable to the leaderboard. Conclusions: On this benchmark, how a model was asked changed its score more than which model was asked. Unprompted scores partly reflect how much a model writes by default, so prompted results should be reported beside unprompted ones before models, or models and clinical tools, are ranked.

Abstract: As an important vehicle for resource integration in the construction of new power systems, the virtual power plant (VPP) has moved from the demonstration and pilot stage into a critical transition period of standardized construction and market-oriented operation. This paper systematically reviews the technological development trajectory and the practical progress of VPPs in China. At the technical level, key advances are reviewed across three core domains: resource perception and adjustable potential assessment; optimal dispatch and control strategies (covering centralized, distributed, and reinforcement learning-based methods); and cloud–edge–terminal platform architecture and information security. At the practical level, the paper traces the policy evolution from the early demand response pilots to the 2025 Guiding Opinions on Accelerating the Development of Virtual Power Plants, surveys grid-led and third-party-aggregator demonstration projects, and analyzes business models and pathways for participation in electricity markets. On this basis, the key challenges facing Chinese VPPs in technical standardization, market access, regulatory frameworks, and data security are analyzed, and international experience from Europe (Next Kraftwerke, Flexitricity), North America (FERC Order 2222), and Australia (Tesla VPP) is summarized. Finally, future development pathways are discussed from four directions: technological trends (digital twins and the integration of large language models), the improvement of market mechanisms, the construction of the policy and standards system, and the cultivation of a multi-stakeholder industrial ecosystem.

Abstract: Embedding the engines in the rear fuselage is a promising concept to reduce aircraft fuel consumption, but it leads to complex load paths and can introduce engine vibrations into the fuselage skin. Sandwich panels with an auxetic metamaterial core are a potential skin concept for this region, as they can be tailored locally and enhance energy dissipation and passive vibration damping. However, modeling the individual cells for a fuselage structure leads to infeasibly large system sizes. This work therefore presents a scale-bridging analysis framework that homogenizes sandwich materials with auxetic cores into shell stiffnesses for macroscale structural design. For this, a first-order computational homoge-nization of the core combined with classical laminate theory and an asymptotic homogenization of the complete sandwich section are considered. Both are compared against a reference model with a resolved core under tension, shear and bending as well as in a modal analysis, with deviations below 6% for the asymptotic homogenization. The homogenized stiffnesses are then used in an isogeometric analysis of a rear fuselage with embedded engines. Under a 2.5 g pull-up maneuver, the core topology and its orientation directly influence the global deformation, making the core topology a design variable at the aircraft scale.

Abstract: Chronic kidney disease (CKD) is a progressive systemic condition frequently associated with sarcopenia, leading to reduced muscle mass, strength, and functional capacity. Reliable and objective assessment tools are needed to monitor neuromuscular status and support rehabilitation strategies. This study aimed to evaluate the test–retest reliability of a portable surface electromyography (sEMG) device (mDurance) during the 30-Second Sit-to-Stand (30-STS) test in patients with CKD. An observational cross-sectional study was conducted in 26 participants (80.8% male; mean age 50.35 ± 12.40 years). Muscle activation was quantified using the Root Mean Square (RMS) amplitude of the rectus femoris during a single-session test–retest protocol with a 20-minute recovery interval. Reliability was assessed using the Intraclass Correlation Coefficient (ICC), Standard Error of Measurement (SEM), Minimal Detectable Change (MDC95), and Bland–Altman agreement analysis. The ICC was 0.828 (95% CI: 0.592–0.926) for single measures and 0.906 (95% CI: 0.744–0.961) for average measures, indicating good-to-excellent reliability. The SEM was 48.40 µV and the MDC95 was 134.17 µV. Bland-Altman analysis showed a mean bias of −24.73 µV, suggesting a small learning effect between assessments. Internal consistency was high (Cronbach’s alpha = 0.924). Portable sEMG demonstrated good-to-excellent reliability for assessing quadriceps activation during the 30-STS test in CKD patients and may serve as a complementary tool for within-session neuromuscular assessment in renal rehabilitation settings.

Abstract: The Multi-Bubble Universe (MBU) model, developed within the framework of Electromagnetic Bridge Theory (BT), provides a phenomenological description of the emergence of spacetime, energy and matter in which quantum and relativistic properties coexist within the same physical process. In this work, the model is extended to investigate the cosmological origin, primordial abundances and nuclear structure of light elements. Following charge fractionation and neutronization, collisions and mixing between spacetime bubbles produced in Small Cold Bangs (SCBs), the conditions for the formation of primordial neutron aggregates are generated. Their evolution results from the competition between binding, aggregation and fragmentation, with spontaneous aggregation structurally allowed up to N = 9. The subsequent fragmentation and beta decay of these primordial aggregates generate the light nuclear species and, through charge rearrangement, drive their quark maps toward alternating ud/du configurations. In this topology, the same elementary DEMS structure describes both baryonic organization and nuclear binding, while the binding-energy analysis indicates a fluid rearrangement of the quark configuration as the nuclear system evolves. The primordial neutronization mechanism simultaneously provides a possible origin for the matter-antimatter asymmetry. The resulting scenario therefore extends the MBU framework from the emergence of spacetime and primordial matter to light-element nucleosynthesis and nuclear structure.

Abstract: Thermophilic microbial electrolysis cells (MECs) may couple wastewater valorization with hydrogen production, but the microbial dynamics influencing their performance remain poorly understood. This study investigated microbial succession and biofilm development in a single-chamber MEC operated for 132 days at 55 °C with fermented sugarcane vinasse under 0.8, 0.9, and 1.1 V. Hydrogen production and microbial colonization were evaluated by gas analysis, scanning electron microscopy, and 16S rRNA gene amplicon sequencing of suspended and electrode-associated biomass. At 0.8 V, hydrogen accounted for 94.7% of the gas phase with a surface-area-normalized H₂ production rate of 30.4 L H₂ m⁻² d⁻¹. During operation at 1.1 V, these parameters reached 96% and 55.4 L H₂ m⁻² d⁻¹. Microscopy confirmed colonization of the carbon-felt anode at the end of operation. The community underwent marked succession: Akkermansia and Pseudomonas were transiently enriched, Caldanaerobius dominated at 0.8 V, and Moorella predominated at the final stage, representing 41.4% of the suspended and 44.9% of the electrode-associated communities. Thermoanaerobacterium increased from 8.1% in suspended biomass to 18.4% on the electrode. These results demonstrate that long-term thermophilic operation selected a specialized consortium comprising fermentative, acetogenic, and potentially electrode-interacting populations while supporting high-rate hydrogen production from fermented vinasse.

Abstract: Gradient-based latent space planning faces a fundamental trade-off: maintaining high-entropy representations for robust perception under domain shift often yields ill-conditioned manifolds that destabilize trajectory optimization. DEGP introduces a framework designed to isolate gradient interference between representation learning and control dynamics via strict architectural separation. However, empirical evaluation demonstrates that structural decoupling alone is insufficient for closed-loop planning (0/50 per condition; 0/200 total), uncovering a fundamental information-usability gap driven by contact-conditional predic-tion errors and cost signal suppression. The gap is not closed by retraining the encoder to be more decodable: a trained encoder whose T-pose decodability matches DEGP’s (R2=0.686) still yields a predictor that captures essentially no contact-conditioned movement (CDR = 0.046, versus the frozen random encoder’s 0.060). To delineate these operational limits, we provide analytical proofs establishing guaranteed spectral bounds on the predictor’s Ja-cobian under distribution shifts. Furthermore, we validate DEGP across manipulation tasks, ntroducing a telemetry-based runtime contract that quantifies the operational boundaries where geometric conditioning preserves planning stability.

Abstract:

Localized-orbital density functional theory (DFT) is widely used to model defects and molecular adsorption on monolayer MoS₂, but the numerical uncertainty of the pristine reference is rarely quantified at the meV scale that governs band-edge ordering. We establish a convergence-validated SIESTA reference for monolayer 2H-MoS₂ using the PBE functional, a double-ζ polarized basis and PseudoDojo norm-conserving pseudopotentials, including fully relativistic spin–orbit coupling (SOC). Mesh-cutoff and k-point errors are below 0.1 meV atom−1. A refined fixed-cell scan gives a0 = 3.196 Å and a layer modulus of 81–84 N m−1. Without SOC, the K and Γ valence-band maxima differ by only 8.0 meV, and a 0.13% biaxial expansion reverses their order; the direct-gap deformation rate (≈−0.11 eV per % strain) is close to the measured optical value. Fully relativistic PBE gives a direct K–K gap of 1.613 eV, a valence-band splitting of 150.6 meV and a K-over-Γ margin of 79.7 meV, which makes the direct-gap assignment robust. The reference transfers to a 75-atom supercell within 0.06 meV per formula unit and provides a quantified baseline for defect and adsorption studies of MoS₂ nanosheets.

Abstract: Geological CO₂ storage requires compressibility assumptions suited to the effective-stress interval and loading path. We assess their adequacy by separating curve approximation, prediction, parameter identification, and storage consequence. An exact minimax bound tests when a constant logarithmic slope cannot meet a specified tolerance. Across 19 published sediment trajectories, full-data calibration of Arc Joint via Optimum Parameters (AJOP) gave a median range-normalized void-ratio RMSE of 1.27% and a maximum of 3.41% for its five-parameter form; 12 fits selected its exact linear member. The quadratic had a lower median error but locally reversed compression in four cases. Separate blocked tests, thirteen independent Boston Blue Clay specimens, and an intact Draupne record expose limits on prediction and transfer. In twelve archived Smeaheia scenarios, compressibility choices changed pressure-screen classifications. The assessment connects tests of simple assumptions, the value of added curvature, and calibration requirements to storage screening, while preserving the distinction between successful loading-curve approximation and field validation.

Abstract: For positive running charged-fermion masses in one scheme and at one scale, define \(A_s=\tfrac14\ln(m_{s,1}m_{s,3}/m_{s,2}^2)\) and \(\Delta_\Pi=A_\ell+2A_d-A_u\). A specified four-channel Pati--Salam source map identifies the primitive correction normal to this plane with the unique route-odd coefficient, \(\delta\Delta_\Pi=-a_-/4\). An exact finite matching identity retains noncommuting kinetic determinants and middle singular values. Adjoint Sp(18) supplies conditional mass reconstruction from current and scalar observables, full-rank neutral--link vacua and a quantitative canonical tree gap under explicit metric bounds. In the distinct antisymmetric \(\mathrm{USp}(6)\) construction, a quark-source pencil and current projections reduce the independent normalization inputs. A spectator-active vacuum preserves matter parity and baryon triality; one tensor operator lifts both strong moduli without new preons. Directional mixing leaves one light Higgs pair and a nonsingular coloured \(H_{15}\) block. An exact four-doublet electroweak example has 13 positive physical scalar directions and three gauge zeros. These results establish compatible local sectors in specified tree effective theories. Ultraviolet coefficient selection, strong-sector backreaction, the full quantum vacuum and physical pole matching remain to be determined. No absolute charged mass follows from the present inputs. A detailed comparison states each construction's achievements and next physical tests without excluding unexamined actions or phases.

Abstract: We re-examine Maynard Smith and Szathmáry’s thesis that ‘human societies and language’ represent a major transition in evolution based on changes in the storage, transmission, and translation of information. We argue that they understated the scope and significance of the transition associated with humans, the most consequential effects of which lie in the translation of large quantities of non-genetic information to structure in the form of artificial creatures (automata) that mimic living organisms. Humans evolved three specialized anatomical features related to the storage, transmission, and translation of non-genetic information (enlarged brain, vocal tract, and hands) that function in concert to compute the solutions to problems of adaptation through an evolutionary computational process with non-genetic information. We treat artifact production sequences dating to 3.3–0.025 million years ago as algorithms and apply algorithmic information theory to measure the amount of information translated to structure (‘program size’). We find that the transition linked to humans is an extended and nonlinear process that may be subdivided into phases based on trends in artifact production program size and algorithmic complexity. The transition will be complete when self-reproducing automata begin to evolve independently of the organisms that generated them.

Abstract: Large language models (LLMs) are increasingly being used to support data analysis and have the potential to make statistical methods more accessible to clinicians and medical researchers with limited programming experience. However, the rapid development of technologies surrounding LLMs has introduced new concepts and workflows that may be unfamiliar to potential users. In particular, tool calling, sandboxing, and data science agents provide different mechanisms through which LLMs can perform statistical analyses, yet the distinctions between these approaches are often unclear. This paper introduces and compares these three developments from the perspective of statistical data analysis. Tool calling allows an LLM to access predefined statistical functions, sandboxing provides a controlled computational environment in which model-generated code can be executed, and data science agents extend these capabilities by combining reasoning, tools, memory, planning, and execution environments to pursue analytical objectives through multi-step workflows. Their application is illustrated using the R programming language together with the ellmer and securer packages. Examples demonstrate how statistical analyses can be performed using predefined functions, code execution within a sandbox, and a simple biostatistics agent. The advantages, limitations, and verification requirements of each approach are discussed, with particular emphasis on transparency, reproducibility, and human oversight. This paper aims to provide clinicians, researchers, and statisticians with an accessible introduction to these emerging technologies and their potential role in LLM-assisted data analysis.

Abstract: Flooded cropland in Sindh had not returned to its counterfactual vegetation condition four years after the 2022 floods, and the shortfall sits almost entirely in the summer (Kharif) season. We built 555,309 300-m cropland cells across 22 districts and tracked monthly Sentinel-2 normalized difference vegetation index (NDVI) and enhanced vegetation index (EVI) from January 2021 to September 2026. Cells with three or more Sentinel-1 water detections during August to October 2022 were treated as flooded and matched one-to-one with non-flooded cells on terrain, drainage proximity, cropland fraction, and pre-flood vegetation level and trend, giving 87,447 pairs with all seven covariates balanced (absolute standardized mean difference below 0.03). An event-study difference-in-differences model shows no pre-flood divergence (k = −1 coefficient +0.003, p = 0.43). Flooded cells fell 0.20 NDVI below controls in Kharif 2022, recovered to −0.06 by Rabi (winter) 2023–24, settled at about −0.11 through Kharif 2026. The result survives a placebo shock, three calipers, leave-one-district-out estimation, and a monotonic dose-response across flood-duration terciles (−0.13, −0.19, −0.28). Integrated Kharif NDVI in flooded cells stayed 0.30 to 0.60 units below controls in every summer from 2023 to 2026, whereas integrated Rabi NDVI exceeded controls from the second winter onward (flood duration × Kharif interaction, γ = −0.32, p = 4.4 × 10−10). Flood duration and post-flood standing-water persistence were the strongest predictors of time to recovery across mixed-effects, spatial, and gradient-boosted models. Trajectory clustering places 17% of matched cells in a persistent-deficit archetype; Larkana and Dadu hold 36% of them.

Abstract: The hyperstructural model of redox reactions organises the oxidation states of an element into an Hv-group whose hyperoperation returns the set of thermodynamically accessible products. We recast this model in the language of general topology. To every hyperoperation ⊕ on a nite set H we attach a topology τ⊕, the reaction topology, generated by the family of hyperproducts {x ⊕ y} as a subbasis. We prove that τ⊕ is an Alexandrov topology whose minimal neighbourhoods are N(x) = ∩ {x ⊕ y : x ∈ x ⊕ y}; that its specialisation preorder admits the chemical reading y accompanies x in every reaction product containing x''; that τ⊕ is T0 exactly when no two species are reactionindistinguishable, and discrete exactly when every species is separated from all others by some reaction; and that the connected components of (H, τ⊕) are the components of the comparability graph of that preorder. We then show that the hyperoperation is continuous for the Vietoris hyperspace topology whenever it is constant on minimal neighbourhoods, so that every Hv-group with discrete reaction topology is a topological Hv-group, and that the quotient by the fundamental relation β∗ is discrete if and only if the β∗-classes are open. The constructions are worked out on the redox data for tin, iron, copper and manganese: the hypergraphs induced by the iron Hv-group yield, respectively, a disconnected space with components {Fe3+} and {Fe, Fe2+}, a connected T0 space, a connected non-T0 space with two Kolmogorov classes, and an indiscrete space, while the copper hypergraph yields a connected, non-discrete T0 space.

Abstract: Cancer metabolic adaptability and treatment resistance provide a rationale for evaluating coordinated interventions across complementary tumor and host processes. This narrative review examines five medications used within the Cancer Metabolic Optimization Protocol (C-MOP) - metformin, atorvastatin, doxycycline, mebendazole, and ivermectin - and describes a physician-directed framework for adjunctive use in adults with active cancer. The central hypothesis is that complementary effects on energy regulation, mevalonate signaling, mitochondrial function, microtubule dynamics, and adaptive stress responses may constrain compensatory pathways and enhance sensitivity to conventional treatment. Selected experimental combinations and early clinical experience with other multi-agent repurposing regimens support investigation of this strategy. Evidence for the individual agents is heterogeneous: metformin and statins have the largest human evidence base, with mixed or negative randomized findings in several settings; doxycycline and mebendazole have predominantly preclinical, translational, and early-phase support. Ivermectin remains the most experimental component, with predominantly preclinical evidence and evolving dosing and long-term safety questions in oncology. The framework links agent selection to patient-specific goals, conventional oncology treatment, organ function, interactions, sequential initiation, monitoring, and reassessment of treatment burden. The clinical benefit of the complete five-agent regimen remains to be established. By defining the combination rationale, patient selection, individualized implementation, and safety procedures, C-MOP provides a foundation for consistent clinical reporting and prospective evaluation.
