This paper examines whether differences in the speed with which traded assets respond to a common market shock can predict subsequent relative returns. The framework combines a lagged rolling factor model with Absorption Gap (AG), which measures an asset’s response error, and Shock Coherence (SC), which characterizes the contemporaneous market state. The public specification is evaluated using executable next-open timing, explicit transaction costs, dependence-aware inference, randomized-signal benchmarks, chronological diagnostics, and machine-learning extensions. The study uses 24 ETFs from 4 January 2010 through 28 August 2026, with eight factor proxies excluded from the 16-asset traded cross-section. The corrected public baseline produces a combined Rank IC of -0.00592, an approximately flat zero-cost gross result, and materially negative performance after transaction costs. A within-date randomized-signal benchmark yields an empirical two-sided p-value of 0.299, while standalone Absorption Gap, coherence-conditioned tests, chronological subsamples, and machine-learning models provide no robust evidence of economically viable public alpha. The contribution is therefore methodological as much as empirical: the paper connects an economic hypothesis about heterogeneous information absorption to an executable trading test, documents why the disclosed implementation fails, separates diagnostic and exploratory analysis from confirmatory evidence, and establishes a reproducible public baseline while keeping the proprietary alpha layer outside the evidence package.

Algal-bacterial biofilms function as stratified microecosystems in which photosynthetic oxygen production and heterotrophic respiration are coupled through counter-diffusive \(\:{\text{O}}_{2}-{\text{C}\text{O}}_{2}\:\) transport. Quantifying this internal carbon loop is critical for designing carbon-neutral and energy-efficient wastewater treatment systems. This study develops a mechanistic two-layer diffusion–reaction model representing an outer phototrophic layer, where CO 2 is assimilated and O 2 is produced, and an inner heterotrophic layer, where O 2 is consumed, and CO 2 is released. Steady-state mass balances with interfacial flux continuity are solved to obtain coupled O 2 and CO 2 profiles across the biofilm. A new dimensionless Carbon Loop Efficiency Index (CLEI) is introduced to quantify the degree of photosynthetic–respiratory coupling based on interfacial gas fluxes. By definition, CLEI = 0 represents a carbon-positive regime with no internal CO 2 recycling, CLEI = 1 denotes complete loop closure and carbon-neutral operation, and CLEI > 1 indicates a potentially carbon-negative regime in which CO 2 assimilation exceeds internally generated CO 2 under the modeled conditions. Model results suggest that, within the validated parameter ranges considered in this study, CLEI approaches unity only within a constrained design window characterized by intermediate total biofilm thickness (approximately 300–500 μm), where oxygen and carbon dioxide transport are balanced through coupled diffusion–reaction processes. Thinner biofilms are carbon-limited (CLEI > 1), whereas thicker biofilms develop oxygen diffusion limitation (CLEI < 1), preventing complete loop closure. Thinner biofilms are carbon-limited (CLEI > 1), whereas thicker biofilms develop oxygen diffusion limitation (CLEI < 1), preventing full loop closure. The framework demonstrates how stratified algal–bacterial biofilms can achieve self-oxygenation and intrinsic CO₂ mitigation through transport-controlled coupling, and provides a mechanistic basis for the rational design of carbon-neutral or potentially carbon-negative wastewater treatment and photobioreactor systems.
The prevailing narrative of the AI race assumes that technological competition culminates in a single winner, a malformed rhetoric that rests on an under-specified concept of victory (Siegel, 2026). Unlike historical technological competitions, the AI race has no agreed endpoint, no universally accepted metric of success, and no consensus on whether achievement should be defined by artificial general intelligence (AGI), frontier-model capability, compute capacity, scientific productivity, economic competitiveness, military advantage, or global diffusion (Akula & Guest, 2026). Consequently, assertions that one state will ultimately win the AI race are conceptually incomplete. This working paper therefore shifts attention from identifying a presumed winner to examining an alternative question: whether strategic influence may depend not only on frontier capability, but also on how AI systems are adopted, trusted, and deployed across third-country markets. The following corpus outlines ten working parts.
This study evaluated the antimicrobial, antioxidant, and total phenolic profiles of nine chestnut honey samples from Yalova, Türkiye, and the bioaccessibility of these compounds using a simulated in vitro gastrointestinal digestion model. Agar well diffusion and broth microdilution methods were used to evaluate antimicrobial activity against Staphylococcus aureus, Escherichia coli, Salmonella Enteritidis, Staphylococcus epidermidis, Listeria monocytogenes, Salmonella Typhi, Bacillus cereus, Enterococcus faecalis, and Candida albicans. Honey samples (100% and 50% v/v) were effective against all microorganisms except C. albicans. The most sensitive strains were S. aureus and S. epidermidis while E. coli and E. faecalis were less susceptible, respectively. The total phenolic content of honey samples was between 59.9 and 77.5 mg GAE/100 g honey. The DPPH radical scavenging activity ranged from 8.46 to 13.27 μmol TE/g, while the ABTS radical scavenging activity was determined to be between 15.40 and 30.47 μmol TE/g. The CUPRAC reduced capacity ranged from 17.68 to 26.79 μmol TE/g. The antioxidant capacity of honey samples underwent significant fluctuations during in vitro gastrointestinal digestion (p < 0.05). While certain parameters declined during the gastric phase, samples H4 and H6 demonstrated remarkable resilience, achieving the highest post-digestive recovery with superior TPC stability and antioxidant retention.
Artificial intelligence (AI) has revolutionized medical imaging with automated disease detection, image segmentation, diagnosis, prognosis prediction, and clinical decision support across various imaging modalities, such as X-ray, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, positron emission tomography (PET), retinal imaging, and digital pathology. Recent advances in deep learning, transformer architectures, multimodal learning and foundation models have significantly improved the diagnostic accuracy and reduced the reliance on handcrafted feature engineering. However, challenges like data heterogeneity, model interpretability, external validation, privacy preservation, computational efficiency, and regulatory compliance still hinder the widespread clinical implementation.In this paper, this review presents a comprehensive study on the evolution of modern AI frameworks in medical imaging by integrating recent methodological advances with perspectives on clinical translation. The review covers the latest deep learning architectures, such as convolutional neural networks, Vision Transformers, hybrid CNN–Transformer models, multimodal learning frameworks, generative artificial intelligence, diffusion models, federated learning, privacy-preserving learning, and medical foundation models. In addition, the review covers the cutting-edge explainable AI techniques, including Grad-CAM, SHAP, LIME, and attention visualization, for boosting transparency and clinician confidence. The review also discusses the state-of-the-art performance optimization strategies, including transfer learning, active learning, domain adaptation, neural architecture search, hyperparameter optimization, model compression, and computational resource optimization. Equally important, the latest developments in clinical validation, external evaluation, robustness assessment, fairness, uncertainty estimation, regulatory considerations, and deployment frameworks are critically analyzed to underscore their role in facilitating safe clinical implementation.The review analysis concludes with the identification of key research challenges and directions for the future including multimodal foundation models, vision-language systems, retrieval-augmented generation,

This volume develops a dynamical form of KM space theory based on admissible presentations. A dynamic presentation consists of a source evolution, a host evolution, an admissible presentation map, and the boundedness, topological, or measurable structures required to compare them. The theory also records admissible compressions, host costs, realization spectra, reflective cores, and the dynamic axioms DK1–DK12. Classical dynamical results and general comparison theorems are retained with their original hypotheses; a theorem is specifically KM only when its proof depends on the presentation structure. For metric phase spaces \(X\) and \(K\), semiflows \(S\) and \(T\), and a continuous map \(\kappa:X\to K\), the orbit comparison is between \(\kappa S(t)x\) and \(T(t)\kappa x\). At this stage, \(\kappa\) is a typed comparison map. It becomes a KM dynamic screen only when induced by an admissible compression, a core morphism, or the unit of a specified dynamic reflector. Vanishing orbit defect gives a semiconjugacy, but does not by itself provide an inverse, a section, or reconstruction of the dynamics hidden in the fibers. The analytic input comes from *KM Space Theory, Volume IV*. Closed generators, semigroup realizations, spectral and Fredholm data, energy forms, and solution spaces are used together with their domains and realization choices. Attractors, invariant measures, entropy, nonlinear stability, asymptotic compactness, statistical stability, and scattering require additional dynamical hypotheses. The theory distinguishes exact semiconjugacy, finite-time approximation, orbit shadowing, asymptotic and statistical comparison, measurable factor maps, conjugacy, extensions, and reverse trajectory lifting. Long-time invariants are organized into typed dynamic profiles that retain presentation costs, structural and presentation redundancy, orbit and attractor defects, invariant-measure and entropy loss, scattering data, and reconstruction groupoids. Reverse problems are formulated through lift spaces, kernel actions, core groupoids, convex fibers of invariant probabilities, conditional measures, relative entropy, and asymptotic-state fibers. Existence, uniqueness, naturality, categorical canonicality, and strict canonical selection are treated as distinct properties. In particular, an attained minimal presentation need not be canonical, a screened attractor need not reconstruct a source attractor, and zero orbit defect need not imply KM equivalence. Finite-state, linear, symbolic, gradient, reaction–diffusion, Markov, skew-product, bifurcation, and scattering models illustrate the framework. The resulting theory provides a dependency-controlled interface for studying long-time dynamics before and after KM screening while sharply separating classical dynamics, typed comparison, and genuinely KM-axiomatic conclusions. Keywords KM space theory; dynamical screening; admissible presentation; dynamic compression; screening reflector; rigid core; dynamic realization spectrum; redundancy profile; semiflow; attractor; invariant measure; entropy; transfer operator; random dynamical system; scattering; kernel dynamics; core groupoid; asymptotic reconstruction.

The Langmuir adsorption isotherm of surface chemistry theta=Kp/(1+Kp), the Fermi distribution of solid-state physics f=1/1+e^(E-mu)/kT, and the Michaelis--Menten expression of enzyme kinetics v/V_max=[S]/(K_m+[S])──these three share a form. This paper asks whether that is an accidental likeness (a rhyme) or the same root──the answer is the same root. No new mathematical theorem and no new law is claimed. Scope of this paper (scope note): No new mathematical theorem and no new law is claimed──the Langmuir, Fermi--Dirac, Michaelis--Menten, Freundlich and BET expressions are all standard. We do not build statistical mechanics──all we use is one change of variable and one division. We do not derive the Fermi distribution──we do not enter the derivation from the grand canonical ensemble. We do not discuss the mechanism of adsorption──heat of adsorption, surface diffusion, and the distinction between chemisorption and physisorption are not treated at all. We do not discuss enzyme mechanism──the Michaelis--Menten expression follows from a steady-state approximation, and the validity of that approximation is not treated. Only the agreement of form is treated. We do not say the three are “the same phenomenon”──what agrees is the form of the distribution function, not the phenomena. The Fermi distribution comes from quantum statistics, Langmuir from an equilibrium constant, Michaelis from reaction rates: the routes of derivation differ. The Michaelis root is weaker──the agreement of Langmuir and Fermi rests on the same root, exclusion, whereas the Michaelis “site” is the separate circumstance that one enzyme molecule binds one substrate. This paper does not claim it as a third case of the same root, and keeps it to the agreement of form. Relation to earlier papers: Paper 112 counted “six distinct roots sharing one rhyme”──this paper is the converse case, an example where not only the rhyme but the root is the same. It is set as the counterpart to 112. Paper 265 showed that what separated the low-temperature models is the density of states──this paper is on the distribution-function side and does not treat the density of states. Paper 274 showed that Drude was right through the cancellation of two errors──the agreement here is not a cancellation but an identity. Paper 220 counted four things called “independence”──the “exclusion” there is the mutual exclusivity of probabilistic events, a different thing from the exclusion of sites here. What is added is confirming at five points that a change of variable makes the difference between the two expressions 0, naming the root as exclusion, confirming that 0.1->0.5 and 0.5->0.9 both take 9 times, and separating the three expressions by the presence or absence of saturation. First, changing the variable makes the difference 0. Setting Kp=e^(mu-E)/kT, the difference at five points is 0 or below 10^-16 (Section 2). Second, this is the core of the paper. The root is that one site takes only 0 or 1, and if the exclusion is the same, the distribution is the same (Section 3). Third, the fuller the sites, the less it acts. Raising theta from 0.9 to 0.99 takes 11 times the pressure; from 0.5 to 0.999 it takes 999 times (Section 4). Fourth, the first half is symmetric. Both 0.1->0.5 and 0.5->0.9 take exactly 9 times (Section 4). Fifth, the same 11 appears on the Michaelis side. Raising v/V_max from 0.9 to 0.99 takes 11 times the substrate concentration (Section 5). Sixth, the separator is whether the number of sites is finite. The Freundlich expression does not saturate, and the BET expression diverges as theta->infinity (Section 6). The Langmuir isotherm and the Fermi distribution are not alike; they are one and the same expression. Merely setting Kp=e^(mu-E)/kT makes the difference at all five points 0 or the size of rounding. The root is one line──a single site takes only 0 or 1. So the grand partition function stops at two terms, and if the exclusion is the same the distribution is the same. Numerical intuition transfers unchanged──the 11 times the pressure needed to raise theta from 0.9 to 0.99 is the same number as the 11 times the substrate needed to raise v/V_max from 0.9 to 0.99. And 0.1->0.5 and 0.5->0.9 both take exactly 9──symmetric about a half. One thing separates them──whether the number of sites is finite. If it is, this form follows; if not, it diverges as Freundlich and BET do. Not the field. Where Paper 112 counted six distinct roots under one rhyme, here the root is the same as well, and that is why the difference is 0.

A task-relative theory of what may be forgotten, what may be ignored in practice, and what need not be physically maintained Reduced representations can be sufficient in at least three inequivalent senses: they may close under a declared family of future continuations, support near-optimal decisions for a specified objective, or admit economical physical realization. We formalize these as structural, operational, and physical future sufficiency. For finite-horizon controlled Markov systems, exact quotient conditions yield Bellman factorization. In finite-dimensional linear systems, backward propagation of task observables gives the minimal robust future-relevance family, with a continuous-time moving-null criterion characterizing exact closure. For finite-horizon linear-quadratic regulation, we define a strong closure residual, construct a nearby exactly closed surrogate problem, and obtain a local quadratic policy-regret certificate. A controlled perturbation experiment reproduces the predicted first-order gain deviation and second-order regret scaling. Exact counterexamples and a diffusion-control comparison show that strong closure is nevertheless not necessary for near-optimal control: performance-oriented reductions can tolerate substantial structural nonclosure and attain much smaller operational order. We then distinguish reduced control dimension from physical realization burden. Effective-support and mobility bounds show that low operational rank need not imply localized or inexpensive implementation, while a Clifford-circuit construction exhibits rank-one observable relevance with extensive Pauli support. The resulting framework treats closure as a robustness guarantee rather than a universal compression optimum and identifies the additional assumptions required to convert informational reduction into physical resource advantage. Keywords: future sufficiency; controlled quotients; model reduction; optimal control; LQR; state aggregation; bisimulation; physical realization; quantum control; coheroputation Scope and claim discipline This paper does not claim that task-oriented model reduction, state aggregation, bisimulation, balanced truncation, reduced Riccati control, observable backpropagation, or a posteriori reduced-control certification are new. Those are mature areas with substantial prior art [3–13]. The contribution is narrower: the paper places robust structural closure, task-performance sufficiency, and hardware-relative physical sufficiency in one explicit hierarchy; develops a particular strong-closure residual and exactly closed surrogate for finite-horizon LQR; and proves no-go separations showing why reduced informational dimension alone cannot be promoted to a physical resource claim.

This work presents an electrothermal optimization study of diamond‐based trench metal oxide semiconductor (MOS) barrier Schottky (TMBS) rectifiers using mixed‐mode drift‐diffusion technology computer aided design simulations under quasi‐static and dynamic reverse‐bias conditions. The influence of drift‐layer thickness, doping concentration, oxide thickness, and trench depth is systematically investigated through electric field and charge‐sharing analysis. Under quasi‐static operation, the breakdown voltage is limited either by the electric field beneath the Schottky contact or at the trench bottom, and optimal BV is achieved when these two peak fields are balanced. Dynamic simulations including incomplete dopant ionization reveal strong modifications of the transient electric field distribution under ultra‐fast voltage ramps. Avalanche initiation is delayed, leading to significant BV enhancement compared to quasi‐static conditions, especially for shallow trench and non‐punch‐through structures. In contrast, self‐heating effects remain negligible due to the high thermal conductivity of diamond. The results demonstrate that optimal TMBS design depends strongly on the operating regime, highlighting the importance of dynamic electrothermal modeling for high‐voltage and high‐frequency diamond power devices.

Sulfur hexafluoride (SF 6 ) is widely used as an insulating and arc-extinguishing medium in high-voltage electrical equipment due to its excellent dielectric properties and insulation performance. However, SF 6 is also a potent greenhouse gas, so mixing SF 6 with an inert gas such as N 2 is a promising way to reduce its usage. The diffusion properties of SF 6 /N 2 mixtures play a crucial role in gas-mixture separation or replenishment, because they determine the proportion and uniformity of the mixtures. By combining ab initio molecular dynamics (AIMD) and machine-learning molecular dynamics (MLMD) simulations of SF 6 and N 2 in SF 6 /N 2 mixtures, we systematically characterize their multiscale diffusion dynamics. At short times, both SF 6 and N 2 exhibit the expected ballistic regime with super-diffusive scaling. At intermediate times, SF 6 shows a more pronounced plateau-like crossover than N 2 , which is consistent with the molecular flexibility of SF6 and the associated rotational and vibrational dynamics. At longer times, both SF 6 and N 2 gradually approach normal diffusion. A theoretical model is also proposed to quantitatively describe the non-Fickian features of the MSD curves. This work provides a more complete physical picture of SF 6 and N 2 dynamics in SF 6 /N 2 mixtures and offers a useful reference for gas replenishment in SF 6 /N 2 mixed electrical equipment.
