Change of direction with the ball preceding goals in high-level men’s football matches: action-level characteristics and positional differences

This study examined action-level characteristics of change of direction with the ball (COD-B) preceding goals in high-level men’s football and further analysed positional differences. Fifty-three knockout-stage matches from the 2018 and 2022 FIFA World Cups, 2020 and 2024 UEFA Eu...

Closed-form optimal design of passive switching dampers for stay cables

Near-anchor linear viscous dampers for stay cables are constrained by the small local motion available for energy dissipation. This study proposes a passive switching damper that mechanically alternates between high- and low-damping states according to motion direction, without s...

Microhybridization enhances intestinal microbiota and glycometabolic regulation in natural gynogenic blunt snout bream derived from the blunt snout bream (Megalobrama amblycephala, ♀) × Chinese perch (Siniperca chuatsi, ♂)

Gut microbiota plays critical roles in host nutrition and metabolism, but research on the intestinal nutrition and gut microbiota of gynogenetic offspring, especially from omnivorous and carnivorous crosses, remains scarce. Intestinal tissues were collected from natural gynogenet...

Access to Sb III -containing polyoxotungstates with structure-dependent catalytic enhancement toward Knoevenagel condensation

Abstract Owing to the unique lone-pair effect and pronounced hydrolytic tendency, the controllable synthesis of SbIII-containing polyoxometalates (POMs) remains a significant challenge. Rather than being confined as internal heterogroup, the employment of SbIII as an accessible m...

Multidimensional Analysis of Ore Spontaneous Combustion Tendency Based on IAHP and Improved Interval Approximation

To conduct a scientific and comprehensive analysis of the spontaneous combustion tendency of sulfide ores and improve the safety production level of sulfur mines, an indicator system for determining the spontaneous combustion tendency of sulfide ores and a comprehensive classific...

Exogenous pillaring engineering toward stable layered potassium manganese oxide cathodes

Layered potassium manganese oxides (KMO) offer a theoretically high energy density but intrinsically suffer from insufficient structural stability driven by Jahn–Teller lattice distortion. Herein, we report a spatially distributed pillaring structure that enables synergistic bulk...

Anion‐Programmed Lewis‐Acidity‐Amplified Cellulose Separators for Dual Interphase Regulation in Li||NCM811 Batteries

ABSTRACT Separators in lithium metal batteries are typically treated as passive ion‐transport membranes, despite their strategic position between two unstable electrode‐electrolyte interfaces. Inspired by Lewis acid‐base regulation in liquid/ solid state electrolyte systems, we r...

Catalytic Insertion of Pd–Vinylidenes Into B─H Bonds

ABSTRACT An unprecedented palladium (Pd)‑catalyzed insertion of unsaturated carbenes into B─H bonds is described. Using alkynyl hypervalent iodine reagents as carbene precursors and amine–borane adducts as boron sources, this method delivers a broad range of E ‑configured alkenyl...

The deep operator finite element method: A discrete variational neural operator for elasticity under variable loading

Learning solution operators for parametric partial differential equations is essential for real-time simulation and engineering analysis. However, existing physics-informed neural operators often suffer from unstable training due to numerical quadrature errors, sampling variabili...

Hierarchical Bonding Induced Promising Thermoelectric Performance in Monoclinic Cs2SnSe3.

Thermoelectric materials capable of directly converting heat into electricity are of great interest for sustainable energy utilization and waste-heat recovery. Here, we systematically investigate the structural, vibrational, thermal transport, and electronic transport properties...

Near‐Unity Linear Polarization of Self‐Trapped Exciton Emission in Cu 3 PS 4 With Highly Anti‐Thermal‐Quenching for Sensitive Optical Thermometry

ABSTRACT Recently, self‐trapped exciton (STE) emission has attracted considerable attention. However, reports on the STE emission in transition‐metal phosphorus chalcogenides remain scarce, and their interesting luminescence and underlying photo‐physical mechanism aren't yet full...

Accurate and explainable ICD-10-CM diagnosis coding through multi-stage model adaptation and evidence-guided verification

The International Classification of Diseases (ICD) coding system is central to reimbursement, registry construction, and secondary analysis, yet automated inpatient International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) diagnosis coding from d...

Green innovative service behaviour through contingent reward transactional leadership

Prior leadership research has largely focused on voluntary pro-environmental behaviour under inspirational leadership, leaving structured reward-based approaches to green service innovation underexplored. This study examines how green contingent reward transactional leadership (G...

Adaptive Knowledge Fusion via Dynamic Stacking for Surrogate-Assisted Transfer Optimization

The integration of transfer learning with surrogate-assisted optimization represents a highly promising paradigm for complex engineering problems. However, it is fundamentally constrained by insufficient cross-domain adaptation and the absence of robust knowledge-fusion technique...

Wearable Sensor-Based Assessment of 24-Hour Movement Behaviors and Physical Fitness Performance in Fire Academy Cadets

Background: This study analyzed the time allocation characteristics of 24-h movement behaviors among firefighter cadets, clarified their independent associations with physical fitness performance, and identified key predictors of physical fitness using compositional data analysis...

Run-length performance of AE-I and AE-II mean charts under phase-I parameter estimation

Adaptive exponentially weighted moving average charts are effective tools for detecting small-to-moderate shifts in a process mean. In practical applications, however, the incontrol mean and standard deviation are usually unknown and must be estimated from Phase I data before Pha...

Electronic Delocalization Steering the Electron-Transfer Pathway in Fe–N/Se–C Catalyzed Peroxymonosulfate Activation

Abstract The sluggish kinetics of interfacial electron transfer, stemming from localized electronic structures, fundamentally limits the practical electron-transfer pathway (ETP) in peroxymonosulfate (PMS) activation. Herein, we demonstrate that engineering long-range electron de...

Comparative proteomics of human anterior lens capsules reveals ATP6V1A-associated lysosomal dysregulation in age-related cataract with primary angle-closure glaucoma

Lens-related mechanisms in primary angle-closure glaucoma (PACG) remain incompletely defined. The anterior lens capsule (ALC) is a biologically active interface, but its molecular landscape in PACG is largely unknown. We aimed to define proteomic alterations in human ALCs from ag...
