Abstract: This paper examines the transmission of monetary policy through bank credit by distinguishing between credit to non-financial corporations and household credit in an emerging economy. Using an ARDL–ECM framework with structural break analysis, it investigates the relationships between credit, the policy rate, and inflation over time. The results suggest that the conventional interest rate channel is limited, as the policy rate does not exhibit a statistically robust association with credit in either the short or long run. Inflation shows a differentiated and context-dependent association, remaining weak for corporate credit but more consistently related to household credit, which may reflect the role of nominal conditions in shaping borrowing behavior. Credit dynamics also differ across segments. Household credit appears more persistent and adjusts gradually, whereas corporate credit is less inertial but more sensitive to instability, pointing to heterogeneous adjustment processes. In addition, the estimated relationships are not stable over time, as their sensitivity to macroeconomic variables varies across periods. Overall, the findings indicate that monetary transmission is heterogeneous and time-varying rather than uniform. These results should be interpreted as conditional relationships within the empirical framework and provide a disaggregated perspective on how macroeconomic conditions are associated with credit dynamics in bank-based emerging economies.

Abstract: Background/Objectives: Eating disorders (EDs) are among the most severe psychiatric conditions affecting young people, with increasing prevalence in the post-pandemic period. This study assessed the prevalence of ED risk and dysfunctional eating behaviors among Italian university students, a population poorly characterized with respect to ED risk, and examined associations with key socio-demographic and anthropometric variables. Methods: A cross-sectional online screening study was conducted between August 2023 and February 2026 with 401 Italian university students (women: n = 306; men: n = 95). Participants completed the validated Italian versions of the Eating Attitudes Test-26 (EAT-26) and the Eating Disorder Examination Questionnaire 6.0 (EDE-Q 6.0), alongside self-reported anthropometric data. Multiple linear regression analyses were performed to identify predictors of ED risk scores. Results: 37.9% of participants had an abnormal BMI (19.7% underweight; 18.2% overweight or obese). EAT-26 scores exceeded the clinical cut-off in 28.4% of participants (women: 35.6%; men: 5.3%). EDE-Q 6.0 global scores exceeded the clinical cut-off in 21.0% (women: 25.8%; men: 5.3%). Only 45.4% showed no anthropometric or psychometric risk indicators. Gender was the strongest predictor of both EAT-26 and EDE-Q 6.0 scores. BMI was negatively associated with EAT-26 scores in the total sample and in women, while a positive association between BMI and EDE-Q 6.0 scores was observed in men. Conclusions: A substantial proportion of Italian university students, particularly women, presented clinically significant ED risk. The combined use of anthropometric and psychometric screening tools provides a more comprehensive risk assessment than either measure alone, highlighting the need for multidimensional screening programs.

Abstract: Palmatine chloride (berbericinine, C₂₁H₂₂ClNO₄) is a protoberberine alkaloid found in several plants including Rhizoma Coptidis, Cortex Phellodendri, Rhizoma Corydalis, Guduchi (Tinospora cordifolia), and Tinospora sagittata roots. Palmatine chloride (PA) is known as an inhibitor of dopamine generation. However, its effect on endoplasmic reticulum (ER) stress-related macrophage activation caused by endotoxin (lipopolysaccharide) is not well known yet. In this study, effects of PA on pyroptotic responses of mouse macrophages (RAW 264.7) activated by endotoxin were investigated using Griess reagent assay for nitric oxide (NO) production, fluo-4 assay for cytosolic calcium release, dihydrorhodamine 123 assay for hydrogen peroxide production, multiple cytokine assay for cytokines production, real-time PCR for inflammatory genes transcriptions, and flow cytometry assay for p38 MAPK activation. Results revealed that PA significantly reduced excessive production levels of NO, hydrogen peroxide, pro-inflammatory cytokines (such as interleukin (IL)-6, CCL3 (MIP-1α), and CSF2 (GM-CSF)), and cytosolic calcium release in endotoxin-stimulated RAW 264.7, but significantly increased the production of anti-inflammatory cytokine IL-10. PA inhibited endotoxin-induced transcripts of Chop, Stat1, Fas, and c-Fos in activated RAW 264.7. It also decreased p38 MAPK phosphorylation and level of Fas in RAW 264.7 stimulated by endotoxin. To further interpret these findings, a network pharmacology-informed analysis based on large-scale literature mining was performed, supporting the multi-target regulatory role of PA in ER stress-related pathways. Briefly, PA exerts anti-inflammatory effects on endotoxin-stimulated RAW 264.7 via calcium-CHOP pathway, consequently reducing endotoxin-induced production of pro-inflammatory mediators (NO, cytokines, etc.) and relieving ER stress-related pyroptotic cascade.

Abstract: Early 2026 has witnessed significant volatility in the oil market, and an energy crisis is expected in the coming months. Large-scale LLM inference continues to consume substantial power in data centers and improving inference efficiency is therefore increasingly important for energy sustainability of AI economy. Semi-structured N:M sparsity, most notably 2:4 (50%) and potentially 1:4 (75%), offers a hardware-friendly path to lower compute and energy, and has been supported in modern GPU designs. Yet existing training methods for 2:4 sparsity (e.g., STE-based approaches) often incur large accuracy drops relative to dense baselines, and practical support for 1:4 remains limited in current software stacks. As a result, attention has shifted toward quantization and mixture-of-experts, leaving high-sparsity N:M pre-training underexplored. Here we introduce a paradigm shift: we treat neural networks as complex systems whose sparse connectivity can be trained using network-science principles formalized by Cannistraci–Hebb sparse-to-sparse training (CHT), coupled with a tailored optimizer. We propose CHTsNM, a sparse-to-sparse training framework centered on Topology-Aware Newton–Schulz (TANS) optimization. TANS makes Newton–Schulz-style matrix updates compatible with dynamically changing semi-structured sparse topologies via active-mask projection, active-support RMS matching, and refresh-aware ramping after topology updates. CHTsNM further incorporates two lightweight mechanisms: Contextually Modulated LoRA (CoMoLoRA) for input-adaptive low-rank residual compensation, and Motif Pattern Revisitation (MPR) to improve exploration of legal row-wise N:M patterns. Across 4 LLaMA pre-training benchmarks, CHTsNM with 2:4 sparsity achieves performance close to dense baselines on most tasks and yields sparse-over-dense gains on 8 tasks. 1:4 sparsity approaches dense performance, though does not yet consistently surpass it. For hardware evaluation, we report measured speedups for native 2:4 execution on current NVIDIA GPUs, and provide a clearly labeled CSR sparse-GEMM surrogate analysis to estimate the acceleration potential of 1:4. Overall, although not implement on hardware yet, our results identify 1:4 sparse pre-training as a promising direction and establish TANS sparse-to-sparse optimization as a practical step toward future high-sparsity N:M accelerators.

Abstract: Forest edge effects are commonly interpreted as radial gradients from the edge toward the interior, but this assumption may oversimplify the spatial organization of heterogeneous tropical forest fragments. Here, we integrated field-based phytosociological data with Sentinel-2 spectral indices to evaluate whether edge-effect interpretation depends on analytical scale in Semideciduous Seasonal Forest fragments embedded in the Brazilian Cerrado. Five fragments were analyzed using transect-based plots and continuous pixel-level modeling. Basal area showed a strong positive correlation with NDVI (r = 0.95), supporting its use as the main spectral proxy for vegetation structure. Plot-level segmented regression detected edge-to-interior transitions, with breakpoints ranging from approximately 13 to 39 m. However, pixel-level modeling revealed scale-dependent responses, including shallow gradients in IF and AC, an intermediate transition in CN, a deeper gradient in IP, and high internal heterogeneity without a single dominant radial transition in Panga. The first two PCA axes explained approximately 81% of the total variance, reinforcing the structural–spectral correspondence. These findings show that edge effects are detectable but not adequately represented by fixed radial zones alone. Pixel-level Sentinel-2 modeling improves the spatial interpretation of fragmented tropical forests.

Abstract: Background: Epiretinal membrane (ERM) is a fibrocellular preretinal proliferation composed of fibroblasts, glial cells, and hyalocytes overlying the internal limiting membrane. Pars plana vitrectomy (PPV) with membrane peeling is the standard surgical treatment, but postoperative cystoid macular edema (CME) can limit visual recovery. Inflammation plays a key role in CME pathogenesis, and corticosteroids may help reduce the inflammatory response associated with both ERM-related traction and surgical trauma. Therefore sustained-release dexamethasone (DEX) intravitreal implants have been investigated as an adjunct to surgery. Methods: A narrative review of the literature was conducted using PubMed and Embase databases up to January 2025. Studies evaluating DEX implants in conjunction with PPV and ERM peeling were included. Both prospective and retrospective clinical studies were considered, in accordance with SANRA recommendations. Results: DEX implantation appears to promote faster resolution of postoperative inflammation and CME, with consistent improvements in anatomical parameters such as central macular thickness. However, the impact on visual acuity remains variable, with some studies reporting earlier functional recovery and others showing no significant long-term benefit. Reported adverse events mainly include intraocular pressure elevation manageable with medical therapy and cataract progression. Conclusions: DEX implant appears to be a safe and potentially effective adjunct to PPV with membrane peeling for ERM, particularly in high-risk eyes, although further large, prospective randomized studies are needed to better define its role.

Abstract: Accurate rainfall data are essential for hydrological forecasting and climate modeling. However, many developing regions, including Tunisia, struggle with significant data gaps in rainfall measurements, particularly from gauge stations. These missing data impair climate model validation and reduce forecasting accuracy across both spatial and temporal dimensions. To overcome these limitations, we conduct a comprehensive evaluation of novel deep learning (DL) architectures designed for imputing missing rainfall gauge data and generating monthly rainfall forecasts. Our framework systematically compares multiple DL approaches: Long Short-Term Memory (LSTM), a hybrid Bidirectional LSTM with a Transformer attention mechanism (BiLSTM-Transformer), and a pure Transformer model. Subsequently, we employ Principal Component Analysis (PCA), K-Means clustering, and quantile techniques to further refine DL model outputs. The processed data are then analyzed using Light Gradient Boosting Machine (LightGBM) to produce final results. Our rigorous evaluation across 47 Tunisian gauges covering 1983–2012 (70% training, 30% testing) demonstrates that the BiLSTM-Transformer hybrid delivers superior performance, achieving an 18.4% reduction in root mean squared errors (RMSE) compared to conventional interpolation methods (14.2 mm versus 17.4 mm monthly error) and improving R2 values by 0.15–0.23 across all test stations. The model shows particular strength in capturing Mediterranean rainfall patterns, correctly predicting 83% of extreme rainfall events (greater than 95th percentile). Furthermore, spatial graph networks boost performance at data-sparse stations by 12.7% through explicit modeling of topographic influences.

Abstract: For a Hutchinson iterated function system (IFS), a Banach contraction on a complete metric space, or a finite-metric dynamical system, a natural question is: at which resolution σ does the contraction's geometric structure (fractal attractor, basin of attraction, periodic part) become optimally visible? We answer this by introducing a scale-selection principle: define the observation scale σ_c := argmax_σ χ(σ), where χ(σ) = |dO(σ)/d log σ| is the susceptibility of a resolution-dependent observable, and prove that σ_c exists under explicit boundary-regularity hypotheses.The framework's main quantitative results are three theorems specialised to Banach contractions and IFS: (i) a geometric scaling identity σ_c = qL for affine Banach contractions with operator norm q and basin scale L, applying directly to Hutchinson IFS with σ_c ∼ q · diam(K⋆); (ii) a discrete Banach theorem on finite metric structures under uniform Lipschitz Lip_d(f) = q < 1, giving an exact collapse-time N⋆ = ⌈log(∆/d_min) / log(1/q)⌉; (iii) a spectral concentration theorem placing σ_c at the inverse log-spectral-gap of the transfer operator at fixed positive noise. A stability lemma for canonical normalisation under smooth windowing and a parametric Banach correspondence observation complete the technical core.The framework is stated explicitly in the non-expansive Lipschitz regime Lip_d(f) ≤ 1 on the metric side, and at fixed positive noise ε ∈ (0, 1) on the spectral side. A four-type classification of operations by injectivity structure organises the broader landscape; cross-domain empirical evidence anchored on a peer-reviewed NISQ-hardware measurement of σ_c is summarised. The middle-thirds Cantor set IFS appears as the principal worked example.

Abstract: The study applies a multiphase, multimethod research approach based on the participatory methodology. It integrates perspectives of professionals in the travel industry and academic experts with the aim to develop an integrated conceptual model of the AI and IoT influence on work, skills development, and job attractiveness in the industry. The research provides a comprehensive understanding of the ways in which digital technologies indirectly shape employment through changes in work processes and development of transferable digital and socio-emotional skills. The paper aimed to donate to redefining the perception of work in tourism and hospitality, emphasizing the sector not only as a career choice but also as a platform for the acquisition of skills relevant in other industries as well. The outcomes revealed that the employees’ aspirations to enter or stay in the industry are not directly influenced by AI and IoT technologies; rather, their effects are mediated through changes in work processes and, more importantly, through the development of skills. The study contributes theoretically by evolving and analytically confirming an incorporated theoretical model that connects technology implementation, work transformation, skills development, and employment outcomes. Practically, the results underscore the importance of human-centered implementation strategies, emphasizing training, communication, and employee inclusion to maximize the benefits of digital technologies.

Abstract: Background/ Objectives: Burn care remains a major clinical challenge, as they require effective wound management to promote healing, reduce pain, and prevent complications. This study aimed to describe the use of a polylactic acid membrane in patients with burns of different depths and to assess wound healing outcomes. Methods: A descriptive case series was conducted including six patients with burn injuries treated with a polylactic acid (PLA) membrane (Suprathel®) at a specialized burn unit. The study was performed according to CARE guidelines. Clinical assessment included burn depth evaluation, pain measurement using the Visual Analog Scale, and scar assessment using the Vancouver Scar Scale. The application of the PLA membrane and its clinical performance during the healing process was described. Results: Complete wound closure was achieved in all cases by re-epithelialization as the PLA adhered, integrated and became transparent, clearly visualizing the progression of healing. Time to re-epithelialization ranged from 14 to 35 days, and final Vancouver Scar Scale scores ranged from 1 to 3 points. No major wound-related complications or local infections were documented during the clinical follow-up period. Conclusions: The use of a PLA membrane in burn management represents a promising advance in wound care, as it was associated with wound closure and pain reduction in this case series, with potential benefits for the optimization of nursing clinical practice.

Abstract: Hero Ridge shale oil reservoirs are characterized by stacked pay boxes, strong vertical heterogeneity, rapid variations in lithology and in situ stress, and significant well-to-well interference during platform-scale three-dimensional development. Conventional fracturing design methods that focus mainly on single-well stimulation are insufficient to simultaneously address fracture propagation, reservoir contact and development economics. Taking the 1H platform and representative wells in the upper member of the Xiaganchaigou Formation (E₃², Boxes 5-6) as examples, this study establishes a workflow integrating reservoir-engineering dual-quality evaluation, single-well parameter optimization, platform-coordinated fracturing, dynamic pore-pressure-stress updating, and EUR-IRR response-surface analysis. Results show that Box 6 has better reservoir quality and fracability than Box 5, with average porosity, oil saturation and brittle-mineral content of 7.6%, 50.9% and 67.6%, respectively. Well 1H6-1, with a 1500 m lateral, penetrated Class I + II sweet spots for 90.6% of the horizontal interval, providing a geological basis for efficient volume stimulation. For conventional sweet-spot wells, the optimal single-well design includes eight clusters per stage, a pumping rate of 18 m³/min, a fluid intensity of 35 m³/m and a proppant intensity of 3.25 m³/m. For 200 m-spaced wells, the pumping rate and fluid intensity should be reduced to 16 m3/min and 32 m³/m, respectively, with 100 m³ of prepad gel to mitigate fracture overlap and stress interference. Further response-surface analysis based on actual EUR-IRR data shows that the highest EUR occurs at a lateral length of 4000 m and well spacing of 50 m (EUR = 566,261 m³), but the IRR is -27.1%. By contrast, the best IRR point is at a lateral length of 4000 m and well spacing of 600 m (IRR = 14.5%), with EUR of 377,500 m³. This demonstrates that the production-optimal and economics-optimal schemes are not coincident. The expanded pilot scheme has an after-tax IRR of 9.31%, after-tax NPV of RMB 131.38 million and payback period of 5.93 years. The results indicate that fracturing optimization in Hero Ridge should move from single-well engineering maximization to integrated decision-making that combines single-well design, platform coordination, lateral-length/well-spacing optimization and techno-economic evaluation.

Abstract: We propose a mechanically programmable nanoscale Chern valve based on an altermagnet–topologicalinsulator (AM–TI) heterostructure, where thin altermagnetic electrodes impose an anisotropic exchange mass on the surface states of a few-quintuple-layer topological-insulator channel. Periodic strain, delivered for example by integrated piezoelectric or surface-acoustic-wave actuators, modulates the inplane crystalline phase of the altermagnetic order and renormalizes the twofold and fourfold interfacial exchange harmonics through zeroth-order Bessel functions. This amplitude-selective renormalization produces re-entrant Chern plateaus, Hall and thermoelectric polarity inversions, and quantized adiabatic charge pumping with winding number changing from 0 to 2. For representative RuO₂/Bi₂Se₃ parameters, the induced gaps remain in the meV range, while MHz mechanical driving places the system deeply within the adiabatic regime. The predicted signatures are directly accessible in nanoscale Hall-bar geometries through the strain-amplitude dependence of transverse Hall response, gate-tracked thermoelectric Hall response, and the collapse of topological sectors near Bessel zeros. The proposed mechanism therefore provides a low-frequency, on-chip route to mechanically controlled topological transport in nano-spintronic AM–TI devices, without optical Floquet driving or net magnetization reversal.

Abstract: This study examined the wood properties, i.e. anatomical characteristics, chemical composition, physical and mechanical properties of seven-year-old plantation-grown B. microphyllum harvested from a research plot at the Forest Research Institute Malaysia. Microscopic analysis revealed diffuse-porous wood with very large solitary vessels, aliform to confluent parenchyma, medium-sized rays, and non-septate fibres. Fibre morphology showed a Runkel ratio below 1.0 and a slenderness ratio of 41.9, indicating favourable fibre flexibility and bonding potential. The absence of tyloses and silica suggests good treatability and machinability. Chemical analysis showed high holocellulose content (79.5–81.9%), α-cellulose (~44%), moderate lignin (22.6–23.9%), and low extractives (0.9–2.1%), indicating a substantial carbohydrate fraction with minimal non-structural compounds. Preliminary phytochemical screening detected flavonoids, tannins/polyphenols, and triterpenes/steroids as dominant constituents, supporting its traditional medicinal relevance. The wood density ranged from 441.4 to 606.8 kg m⁻³ (mean: 524.1 kg m⁻³), classifying the timber as light to moderately heavy. Shrinkage at 15% moisture content was 2.2% (tangential), 1.2% (radial), and 0.6% (longitudinal), giving a tangential-to-radial ratio of 1.6 and indicating moderate dimensional stability. Despite being harvested at only seven years of age, B. microphyllum exhibited mechanical properties comparable to or superior to several commonly planted fast-growing species, such as Eucalyptus nitens, rubberwood (Hevea brasiliensis), and batai (Paraserianthes falcataria). In particular, the bending and shear strengths were considerably higher than those reported for some older plantation timbers. These findings suggest that B. microphyllum has strong potential as a fast-growing plantation timber with favourable strength characteristics and other promising properties, making it a suitable candidate for structural and value-added wood applications.

Abstract: Background: To inform epidemic control, Rapid Test for Recent Infection (RTRI) assays, such as the Asanté HIV-1 Rapid Recency Assay (ARRA), have been developed to detect potential signals of increased HIV acquisition. However, ensuring the accuracy of these tests remains a challenge in resource-limited settings. While ARRA has been implemented for surveillance, there is a lack of documented experiences and lessons learned regarding quality assurance through Proficiency Testing (PT). This study examined Uganda's recent HIV infection PT program from 2020 through 2022 to highlight challenges and successes of implementation in resource-limited settings. Methods: We analyzed proficiency testing (PT) implementation for HIV recency testing in Uganda from 2020–2022. The study included biannual PT cycles (Cycle 1: Jan–Jun, Cycle 2: Jul–Dec) across 676 facilities in 133 districts. We assessed performance using pass rates (percentage of testers correctly identifying all samples in a PT panel) and response rates (proportion of testers submitting results within the stipulated timeframe out of the total number expected to participate). To evaluate sustainability, we longitudinally tracked a fixed cohort of the first 175 testers enrolled at the project's inception, representing diverse facility levels and cadres. Results: Analysis of six proficiency testing cycles from 2020-2022 revealed two key trends: a significant expansion in program participation and a concurrent longitudinal decline in performance among a consistent cohort. Overall, participation grew from 175 testers in Cycle 1, 2020, to 568 testers by Cycle 2, 2022. Among all participating facilities in each cycle, pass rates fluctuated, ranging from a high of 87.3% (Cycle 2, 2020) to a low of 54.9% (Cycle 2, 2021). A longitudinal analysis of the initial 175-testing-site cohort, however, revealed a significant inverse relationship between participation and performance. Non-response within this cohort increased drastically from 0% to 81.7% by early 2022 (p-value for trend <0.001). Among the diminishing subset of sites that continued to submit results, the pass rate showed a statistically significant declining trend, from 85.1% to 76.6% over the study period (p-value for trend = 0.012). Conclusion: This study identified three critical challenges: a steep rise in non-response, declining pass rates, and persistent performance gaps at lower-level health facilities. To address these gaps, we recommend individual tracking with digital feedback and targeted mentorship to re-engage staff and sustain competency at lower-level facilities.

Abstract: Complex percutaneous coronary intervention (PCI) represents a growing proportion of contemporary coronary revascularization, driven by aging populations, increasing comorbidity burden, and advances in interventional techniques. Complex PCI encompasses a spectrum of anatomically and procedurally challenging lesions, including left main disease, bifurcation lesions requiring two-stent strategies, chronic total occlusions, long stent lengths, severe calcification requiring atherectomy, and multivessel revascularization. Antithrombotic therapy, comprising antiplatelet and anticoagulant agents, is essential for preventing stent thrombosis and other ischemic events in both the early and long-term phases after PCI. While antithrombotic therapy mitigates ischemic risks associated with complex PCI, these patients frequently carry high-bleeding risk, thus making the choice of antithrombotic regimen challenging. Recent guideline recommendations emphasize balancing ischemic and bleeding risks rather than relying solely on procedural complexity. This review synthesizes contemporary evidence, guideline recommendations, and clinical considerations for antithrombotic therapy after complex PCI.

Abstract: Rel/SpoT family enzymes participate in controlling the cellular levels of the alarmone (p)ppGpp, thereby activating the stringent response and promoting survival under stress conditions. These proteins contain an N-terminal catalytic domain and a C-terminal regulatory domain. They catalyze both the synthesis of ppGpp/pppGpp from ATP and GDP/GTP and their hydrolysis to GDP/GTP and pyrophosphate. Here, we report the crystal structure of the N-terminal domain of Rel from Streptococcus equisimilis (Rel_Seq385) in complex with pppGpp at 3.2 Å resolution. The asymmetric unit contains a dimer with asymmetric ligation, in which pppGpp occupies only the synthetase site in one monomer, whereas it is observed in both the hydrolase and synthetase sites in the other. Molecular dynamics simulations supported this binding arrangement for the monomer with both sites occupied and revealed additional probable transient binding sites that may contribute to alarmone binding.

Abstract: Traditional food systems are increasingly threatened by industrialised agri-food production, which relies on standardised processes, economies of scale, and lower production costs. This transformation risks undermining not only the economic viability of artisanal producers but also the cultural heritage, local knowledge, pastoral practices, and territorial identities embedded in traditional foods. This study investigates whether consumers’ willingness to pay a premium for traditionally produced foods can help safeguard rural cultural heritage in a competitive PDO market. Focusing on an Italian cheese, the Fiore Sardo PDO, the research combines a Bertrand duopoly framework with the Theory of Planned Behaviour (TPB) to examine the relationships among market competition, consumer beliefs, and support for traditional production systems. Data from 1,640 Italian consumers were analysed using structural equation modelling. The results show that attitudes towards cultural preservation, social recognition of traditional production, and perceived support for rural shepherd communities significantly influence consumers’ willingness to purchase and pay higher prices for traditionally produced cheese. Consumers associate artisanal production not only with superior sensory quality and authenticity but also with the protection of cultural identity, traditional pastoral knowledge, and rural landscapes.

Abstract: Given the "dual-carbon" goals of China, research has been carried out on the impact of the digital economy on carbon emission intensity. Based on the panel data of the 288 cities in China from 2013 to 2022, a two-way fixed-effects model is employed in this paper to study how the digital economy affects carbon emission intensity at the level of cities and urban agglomerations. The results show that the development of the digital economy reduces the intensity of urban carbon emissions, and there is cross-regional spatial spillover at the level of urban agglomerations. According to the results of the mechanism test, there are two paths for "industry-technology" transmission: At the city level, the digital economy can reduce pollution by improving the structure and upgrades of the industrial system; At the level of urban agglomeration, it can strengthen green-technology innovation capabilities. According to the analysis of heterogeneity, polycentric agglomeration, optimisation-and-upgrading type agglomeration and coastal areas have relatively good carbon reduction effects. Based on the above, personalised regional policies will be formulated to promote the development of the digital economy in line with carbon reduction objectives.

Abstract: Corridor management—such as reliance on manual warning zone delineation and inconsistent boundaries—this paper proposes 3DSim-WZD, an automatic ground-level warning zone detection method based on 3D simulation data augmentation. Guided by "interpretable geometric priors combined with deep learning regression," the framework integrates four modules: parametric simulation generation, simulation-to-real transfer, boundary vertex regression, and voltage-level-based expansion. Specifically, parametric virtual scenes are constructed in Unity3D to automatically derive accurate vertex labels. The open-source Stable Diffusion framework, combined with ControlNet and LoRA, is employed for sim-to-real style transfer to reduce domain gaps. Furthermore, directional detection convolutional kernels are incorporated into the YOLO12m backbone to enhance sensitivity to transmission structures. Finally, safety clearance distances are mapped according to voltage levels for regulatory-compliant warning zones. Evaluated on a dataset of 5,000 simulated and 300 real samples, the method achieves a mIoU of 91.2% and an inference speed of 46.8 FPS, demonstrating significant potential for large-scale deployment.

Abstract: Background: The thermodynamic cost of local large language model (LLM)inference on consumer hardware is poorly characterised. Unlike data-centre deployments with hardware power monitors (NVML, RAPL), Apple Silicon unied-memory systems require alternative instrumentation strategies, and no Landauer-grounded framework for local inference energy has previously been validated. Methods: We deploy seven open-source LLMs (2.020.2 GB; 3.2B32.8B parameters, Q4_K_M quantisation) on a single Apple M5 MacBook Pro (32 GBunied memory, 25 GB Metal GPU VRAM) via Ollama v0.23.2, instrumentingthe system with a custom telemetry daemon (1.5 s polling; top, vm_stat, ioreg,ps). We apply the Kerimov-Alekberli (KA) information-geometric framework, which monitors KL divergence between consecutive output distributions relative to a Fisher Information Metric (FIM)-derived threshold (τ = 0.065), and compare energy consumption against an unoptimised baseline using a unied Pythoncode-generation benchmark. Energy estimates are grounded in Landauer's ther-modynamic lower bound E_min = k_BTln 2, scaled macroscopically by an empirical power-size model. Results: KA achieves a consistent 38 % energy reduction across all seven models, saving 59 mJ (llama3.2, 2.0 GB, 55.7 tok/s) to 32,841 mJ(qwen3:32b, 20.2 GB, 2.6 tok/s) per run. Measured power draw follows a linear modelP = 5.0 + 0.75 SGB W (R² = 0.97). Token eciency under KAranges from 1,321 tok/J (qwen3:32b) to 8,287 tok/J (llama3.2). The First-PassageTime (FPT) anomaly detector recorded 602 KL-divergence threshold exceed ancesacross 9,501 total inference tokens; the highest-energy model (qwen3:32b) regis-tered 562 anomalies and the greatest absolute saving. Conclusions: These results constitute the first empirical validation of a Landauer-grounded energy reduction mechanism in local LLM inference via an information-geometric output-distribution stabilisation framework, with extrapolated annual savings of 105.4 kJand 11.7 mg CO₂ per workstation.
