Buoyancy-driven convection in Julia-fractal cavities with iteration-dependent boundary evolution

This study investigates buoyancy-driven convection in cavities with Julia-type boundaries, with particular emphasis on Siegel disk configurations. The boundary geometry progressively evolves with the Julia iteration level n , enabling systematic investigation of iteration-depende...

Emergency Evacuation in Classrooms: A Review

Classroom evacuation is constrained by relatively fixed occupant positions, dense desk-and-chair arrangements, restricted aisles, and limited exits, and is jointly influenced by occupant behavior, spatial conditions, and emergency scenarios. This review proposes a four-stage fram...

Prediction and analysis of displacement response of submerged floating tunnel under impact loading based on machine learning and SHAP methods

Submerged floating tunnels (SFTs) are prone to accidental impact hazards such as ship anchoring and vessel collisions. Existing displacement prediction methods suffer from limited working condition coverage, ambiguous nonlinear multi-factor coupling mechanisms, and the black-box...

Multi-omic data integration model based on inductive graph learning and cascaded co-attention for cancer classification

Abstract A comprehensive analysis of data from multiple omics is essential for devising precise therapeutic strategies for complex diseases. The effective integration and analysis of multi-omic data can boost the precise classification of disease subtypes. However, existing metho...

Autogenous force-mediated assembly: A general strategy for constructing single-atom architectures in hierarchical hybrid electrocatalysts

The design of efficient and pH-universal ruthenium (Ru) single-atom catalysts (SACs) remains a pivotal challenge for hydrogen economy systems. Here, inspired by tubular capillary phenomena, a novel approach is introduced—autogenous force-mediated assembly—enabled by a unique asym...

Modeling cross-media agenda interactions in the international communication of Chinese culture using multi-source news time-series data

Abstract Modeling cross-media agenda evolution is challenging because media agendas involve both temporal dependence in issue salience and structural reconfiguration among issue associations. Most existing intermedia agenda studies rely on contemporaneous correlations or simple l...

Can Intangible Cultural Heritage Resources Stimulate Regional Entrepreneurial Activity?—Empirical Evidence from the Guangxi Zhuang Autonomous Region

In line with the world’s goals of sustainable development, cultural resources are now being used to promote both cultural inheritance and regional economic revitalisation. This paper studies whether intangible cultural heritage (ICH) resources can promote regional entrepreneurial...

The effect of the China-Thailand railway on Thailand’s trade with China Guangxi Province

This study assesses how the China-Thailand Railway may reshape Thailand’s trade with Guangxi by altering the relative competitiveness of road, rail, and sea freight. A mixed-methods framework is employed, combining literature and secondary data with expert interviews, the Analyti...

Characterization of Escherichia Phage ND-4 Against Avian Pathogenic Escherichia coli IMT5155 and Its Preliminary Application in Chicks

Colibacillosis caused by avian pathogenic Escherichia coli (APEC) remains an important bacterial disease in poultry production and is increasingly difficult to control because of antimicrobial resistance. In this study, a lytic phage, ND-4, was isolated from poultry-farm sewage u...

Leaf–Litter–Soil C:N:P Stoichiometry Varies with Stand Age in Three Subtropical Plantation Types

Stoichiometry provides an integrative framework for evaluating nutrient dynamics in plantation ecosystems. However, whether stand-age-related changes in leaf–litter–soil carbon (C), nitrogen (N), and phosphorus (P) stoichiometry are consistent among plantation types remains uncle...

Network identification and key influencing factor analysis of low-carbon economy synergy efficiency in Chinese cities: an interpretable machine learning approach

Against the background of China’s dual-carbon strategy, improving the synergy efficiency of urban low-carbon economies is essential for achieving sustainable economic and social development. This study investigates the spatial association network of low-carbon economy synergy eff...

Spatiotemporal evolution and nonlinear drivers of land surface temperature in the Guangdong–Hong Kong–Macao Greater Bay Area from 2000 to 2020

Against the dual pressures of global warming and rapid urbanization, understanding the evolution and driving mechanisms of urban thermal environments is essential for sustainable urban development. Using multi-source remote sensing, land-use, landscape pattern, and socioeconomic...

Environmental and system-level factors associated with emergency medical service utilization and immediate on-scene symptom response: a population-based study

Abstract Background Suspected cardiopulmonary emergencies represent a major component of EMS demand and are highly sensitive to environmental exposures. However, the combined impact of these dual macro-environmental and micro-operational stressors on prehospital treatment effecti...

On the Periodic Cauchy Problem for the μ‐Modified Camassa‐Holm‐Novikov Type Equation

ABSTRACT This paper delves into the intricate periodic Cauchy problem associated with the ‐modified Camassa‐Holm‐Novikov equation. We first rigorously demonstrate that the occurrence of blow‐up phenomena in this equation is exclusively manifested through the formation of breaking...

Dual‐Response Photoluminescence of Halide Double Perovskite for Novel Self‐Calibrating Thermometers, Multicolor Anti‐Counterfeiting and White LED

ABSTRACT Lead‐free halide double perovskites (LHDPs) as potentially luminescent materials are gaining recognition owing to their multi‐stimuli responsive and tunable spectra. However, the current single functionality and luminescence mode limit further application and development...

Spatiotemporal Dynamics and Zoning Optimization of Territorial Functional Adaptation in the Yunnan–Guangxi Border Region of China from a Development–Security Perspective

From the perspective of coordinating development and security for high-quality development in border regions, this paper focuses on the adaptation relationship between development and security functions in the Yunnan–Guangxi border region. The study aims to characterize the spati...

Teacher motivation and teacher-perceived student performance: The mediating role of teacher self-efficacy and the moderating roles of workload and school climate

Grounded in job demands–resources theory, this study examined whether teacher motivation was associated with teacher-perceived student performance directly and statistically indirectly through teacher self-efficacy, and whether workload and school climate conditioned the first-st...

From the norms on social media to young people’s online aggressive behavior: the mediating effect of moral disengagement

Purpose In the social media era, cyberspace can foster undesirable norms that erode moral boundaries and fuel cyber aggression, especially among young people. Integrating the Theory of Normative Social Behavior and the Theory of Planned Behavior, this study systematically explore...

Effects of Chemically Modified Three-Dimensional Porous Graphene for the Optimal Rheology and Mechanics of Cement Composite

Abstract Although graphene significantly enhances the performance of cement-based materials, its tendency to agglomerate in strongly alkaline cement paste environments and its high cost limit practical applications. To overcome these challenges, this study employed polycarboxylat...
