Combinatorial Sampling and Wear Behavior of Cr-Al-C-N Coatings Deposited by HiPIMS

CrAlN PVD coatings are frequently used to protect cutting tools because of their superior hardness and wear resistance. However, the influence of carbon addition to such coatings remains largely unexplored. Therefore, Cr-Al-C-N coatings were deposited by HiPIMS using a commercial...

Technical Specification for the Scientific Discovery Operating System: Mathematical Formalization and Engineering Architecture —A Proceduralized Knowledge Discovery Protocol Based on the Factor Hierarchy Law and Testability Norms

Tang (2026g) established the theoretical framework of the Scientific Discovery Operating System, providing the first complete definition of the Factor Hierarchy Law—including the dichotomy of regime factors and execution factors, the three morphologies of regime factors (pure reg...

Nuclear Energy in the Sustainability Equation: A Method of Moments Quantile Regression Analysis (MMQR) of Load Capacity Factor in OECD Countries

Nuclear energy has attracted significant interest from policymakers because of its potential to improve environmental sustainability (ES). This study investigates the interplay among nuclear energy consumption (NEC), economic growth (GDP), renewable energy utilization (REN), urba...

The Triple Demotion of the Nuclear Shell: The Shell Model, the Liquid Drop Model, and the Independent-Particle-Motion Axiom ——Derivational Demotion Based on 2D Ising Exact Solution Calibration, Continuous Sphericity Weight Recovery, and the QCTI Index

The central axiom of the traditional shell model—nucleons moving independently in a static mean field—and the liquid drop model have coexisted for nearly nine decades without resolution. Drawing on Tang (2026v) and Tang (2026w), this paper integrates five lines of evidence to com...

Regime-Switch Network and the True Structure of the Nuclear Shell: Internal Self-Consistency of the Confirmed-Breakpoint Network, Completeness Audit of the Shell Model, and Fifteen New Discoveries ——Transition-Zone Width Theorem, Cascade Skeleton, Liquid-Drop Masking Effect, and Shell-Correction Compensation Traces Based on Multi-Tool Aggregation

What is the true structure of the nuclear shell? The traditional shell model holds that the nuclear shell is marked by a few isolated magic numbers—N = 2, 8, 20, 28, 50, 82, 126. This paper finds that the nuclear shell is instead a multi-level network of blind-detected breakpoint...

Nuclear Shell Regime Audit: The Magic-Number Shift Theorem and the Discovery of the N=14 Statistical Rupture ——The η Hierarchy Structure, Bai-Perron Optimal 10 Breakpoints from Zero-Preset Exhaustive Search, and Six Quantitative Theorems

The central axiom of the nuclear shell model—that nucleons move independently in a static mean field—has never been systematically questioned. This paper deploys the Factor Hierarchy Law to nuclear physics for the first time, performing a zero-preset regime audit on the full AME2...

Integrating Course-Based Competitions into Strategic Management Instruction: A Reproducible Course Improvement Protocol

Strategic Management instruction requires students to apply analytical frameworks to uncertain, resource-constrained, and trade-off-based business situations. Course competitions can support this process when they are organized as a structured instructional system rather than as...

Exponential convergence can happen in weighted Birkhoff averages via quasi‐periodicity with arbitrary nonresonance and low regularity

Abstract Since Krengel's work [Monatsh. Math. 86 (1978/79), 3–6] in 1978, it has been widely known that no effective rate of convergence exists in the ergodic theorem. For toral translations, however, by choosing appropriate weights one can accelerate the convergence of ergodic a...

Selective Stabilization of PSI-Associated Electron Transport Network Underlies Cytokinin-Mediated Delay of Leaf Senescence in Barley

Leaf senescence progressively remodels the photosynthetic apparatus, leading to impaired electron transport and declining carbon assimilation. Here, we investigated how dark-induced senescence (DIS) and exogenous 6-benzyladenine (BA) affect photosystem function, cyclic electron f...

Hierarchical Scheduler with Adaptive Time-Budget Reallocation for Time-Triggered Edge-Fog-Cloud Architectures

The lack of determinism restricts the integration of safety-critical applications into Edge–Fog–Cloud (EFC) architectures. Existing EFC schedulers are typically designed for dynamic, best-effort operation based on unmanaged resource allocation and elastic virtualization. This par...

Acupotomy Regulates the RIC8A/P38 MAPK Axis Based on the CircRNA Scaffold to Promote Cartilage Repair in Knee Osteoarthritis

Knee osteoarthritis (KOA) is characterized by progressive cartilage degeneration and inflammation. This study investigated the therapeutic effects of acupotomy in a rabbit model of KOA and its association with the circular RNA phosphodiesterase 4B (circPDE4B)/resistance to inhibi...

Diastereoisomerism and SIM Behavior in Mononuclear Co(II) Systems Based on Mepirizole

Two diastereoisomers of bis(mepirizole)bis(isothiocyanato-κ,N)cobalt(II) (1 and 2) are isolated from the reaction of cobalt(II) thiocyanate and mepirizole, depending on the crystallization solvent (ethanol, 1; acetonitrile, 2). In both crystal structures, the Co(II) ions exhibit...

Core Buildup Composite Resins Bond Strength to Dentin and Microhardness Using Universal Adhesives

The peer-reviewed literature on the use of universal adhesives (UAs) with core build-up composite resins (CBCRs) is limited. UAs may enhance the polymerization of dual-cured composite resins, leading to increased microhardness due to the "touch-cure" effect. Thi...

Bystander Effect Induced by Electrical Stimulation Promotes N2a Differentiation Through Interleukin-6

The bystander effect describes the induction of responses in non-targeted cells through cell signaling by directly stimulated cells. While this phenomenon has been extensively studied in the context of ionizing radiation, its occurrence following electrical stimulation (ES) remai...

Are Attributions of Consciousness to AI Chatbots Epistemically Innocent?

Abstract Artificial intelligence (AI) chatbots (e.g., ChatGPT) can communicate in strikingly humanlike ways. This has prompted many chatbot users to attribute psychological properties, including consciousness, to these systems. However, there is little scientific evidence that cu...

Evaluating Dynamic and Static GNSS-Derived PWV Metrics for Heavy Rainfall Characterization in Cyprus

Global Navigation Satellite System (GNSS)-derived precipitable water vapor (PWV) has become an important source of atmospheric moisture information for severe weather monitoring. While previous studies have primarily relied on static GNSS-derived PWV metrics, comparatively little...

Predicting driving performance from resting-state EEG using explainable gradient boosting

Abstract Sleep deprivation substantially impairs driving performance, underscoring the need for Electroencephalography (EEG)-derived markers associated with driving-performance vulnerability under varying levels of sleepiness. In this study, resting-state EEG signals were recorde...

DEGA: A Deterministic Diagnostic Evidence Governance Agent for Industrial IoT—A DUDU-BLDC Case Study

Industrial diagnostic systems increasingly combine machine-learning classifiers, temporal models, uncertainty surrogates, and explanation methods. Their operational use requires a separate mechanism that determines whether the available evidence is valid, mutually consistent, suf...

Racial/ethnic disparities in economic hardship: the role of financial capability

Purpose Previous research shows that the capability approach is associated with lower poverty rates and higher well-being. Nonetheless, little research applied this approach to understanding economic hardship. To fill this gap, this study applies this approach to explore whether...
