Spatio-temporal prediction and macro-level correlates of hand injuries in manufacturing regions: a multi-source data fusion study using graph neural networks and its implications for targeted prevention

Abstract Background Hand injuries impose a heavy burden on manufacturing-intensive regions, yet the spatio-temporal patterns of regional risk and their macro-level correlates remain poorly understood. Most existing studies focus on individual-level risk factors and rely on single...

Risk-aware hierarchical reinforcement learning for investment and operations in cross-border energy supply chains under the belt and road initiative

Abstract Cross-border energy supply chains under the Belt and Road Initiative (BRI) face unprecedented challenges, including geopolitical instability, macroeconomic volatility, and operational disruptions. Traditional optimization or flat reinforcement learning (RL) methods often...

Vacuum‐Induced Surface Reconstruction of Mn–Ce Oxides for Low‐Temperature Coupled Redox Catalysis

ABSTRACT Low‐temperature redox catalysis over mixed oxides is typically optimized by tuning bulk composition, yet the decisive chemistry occurs at the surface and subsurface interface. Here, we show that this interface can be deliberately reconstructed to enhance Mn–Ce oxide cata...

Ultra-sensitive 2D Dion−Jacobson perovskite phototransistors for optoelectronic neuromorphic computing

Metal halide perovskite semiconductors demonstrate significant advantages over traditional semiconductor materials in next-generation weak-light-responsive devices, owing to their exceptional photoelectric conversion capabilities and outstanding charge transport properties. Under...

Biomechanical and neuromuscular correlates of DaeDo output during successful dominant- and non-dominant-leg taekwondo side kicks: a repeated-measures study

Abstract Objective This study aimed to compare temporal, kinematic, kinetic, and support-side neuromuscular characteristics between dominant- and non-dominant-leg Taekwondo side kicks and to examine their associations with DaeDo output during successful scoring trials. Methods Tw...

The Evolution of Metal Halide Perovskite Transistors

ABSTRACT Metal halide perovskites (MHPs) offer a revolutionary pathway for next‐generation field‐effect transistors (FETs) because of their exceptional carrier mobilities and cost‐effective processability. However, their transition to practical electronics is significantly challe...

Deep learning-based intelligent generation model for intangible cultural heritage products

Rapid digital transformation highlights the urgent need to preserve Intangible Cultural Heritage (ICH), as traditional methods face declining craftsmanship, limited innovation, weak cultural conditioning, poor optimization, and reduced creative diversity, leading to less authenti...

Spatiotemporal patch identification and multiscale drivers of nonagricultural conversion of cultivated land in the Jianghan Plain

Abstract The nonagricultural conversion of cultivated land (NACCL) poses a major challenge to cultivated land protection and food security in intensive agricultural regions. However, the reliable identification of NACCL in complex agricultural plains remains difficult because cul...
