Effect of Fiber Dosage and Age on Creep Failure of Alkali-Activated Slag Concrete Under High Stress Sustained Loading

Alkali-activated slag (AAS) has emerged as a sustainable alternative to Ordinary Portland Cement (OPC), offering a viable pathway for mitigating global environmental footprints. However, its widespread structural application is often hindered by pronounced time-dependent creep de...

A new inquiry into the fundamental module of Sui-Tang Luoyang layout based on compositional proportions

Abstract Sui-Tang Luoyang was an international metropolis in the 7th–10th centuries. The 50- zhang unit has long been regarded as the fundamental module for the layout design of this capital. Taking the Danei as the benchmark, this study determines the modular relationships acros...

Associations of menstrual cycle length with GDM and gestational hypertension in frozen embryo transfer

Prolonged menstrual cycles may indicate potential cardiometabolic conditions; however, there are limited data on how these associations vary among women without polycystic ovary syndrome (PCOS) undergoing in vitro fertilization (IVF). In this study, we aimed to investigate the as...

Tailoring the Mechanical and Acoustic Resonance of Ramie‐Blended Woven Epoxy Composites via Plasma and Alkaline Surface Modifications

ABSTRACT Natural fiber composites require a balance between reinforcement architecture and fiber–matrix interactions for favorable mechanical and vibroacoustic performance. This study examined the effects of weave architecture (plain, twill, satin) and surface modification, plasm...

Adaptive Evolution of Community Response Organizations in Public Health Emergencies: A Grounded System Dynamics Case Study from China

Public health emergencies often unfold over extended periods and place sustained pressure on community-level governance, particularly when demands for supplies, information, medical access, and daily support exceed routine service capacity. This study examines how community respo...

Morphology‐Engineered Bismuth‐Porphyrin MOFs for H 2 S Scavenging Mediated Synergistic Photo‐Immunotherapy Against MRSA‐Infected Diabetic Wounds

ABSTRACT Diabetic wounds infected with methicillin‐resistant Staphylococcus aureus (MRSA) pose a significant challenge to clinical healing. Proliferating MRSA not only invades neutrophils to induce immunosuppression but also produces hydrogen sulfide (H 2 S) and forms biofilms to...

Longitudinal spatial multi-omics delineates tumor microenvironment remodeling across sequential EGFR-TKIs in EGFR-mutant NSCLC

Abstract Background Resistance to therapy is a frequent occurrence in patients with epidermal growth factor receptor (EGFR)-mutant non-small-cell lung cancer (NSCLC) who are treated with EGFR tyrosine kinase inhibitors (EGFR-TKIs). However, spatial information on how the tumor mi...

Quality or convenience? Behavioral evidence on how facility grade influences urban destination choice

Modeling non-work activity destination choices is essential for urban transportation planning, as these activities involve greater flexibility and more complex behavioral decision-making than mandatory activities. However, existing studies often treat all facilities within the sa...

Improving Ventilation Performance in a Multi-Storey Solar Chimney System Using Neutral Plane Analysis: A CFD Case Study

Multi-storey solar chimneys are often evaluated using shaft-outlet airflow, which may conceal uneven airflow distribution among floors. A shaft may provide adequate extraction while upper floors receive insufficient air or experience reverse airflow. This study examined the relat...

Predictive analysis of construction accident outcomes using explainable artificial intelligence and evidence fusion techniques

Purpose Effective construction safety management relies on interpretable information to guide practitioner interventions. However, most current predictive models are “black boxes” that provide limited insight into the complex, multifactor causal mechanisms of accidents. Therefore...

AI4AI Survey: From Long-Horizon Agents to Recursive Self-Improvement — Definitions, Reliable Horizons, and Open Problems

Can AI improve AI? AI agents can now run experiments, modify code and training pipelines, and iteratively improve AI artifacts. Yet the literature remains fragmented across long-horizon agents, AI for AI (AI4AI), self-improvement, and recursive self-improvement, making it difficu...

Spatiotemporal Deep Learning for Continuous Illumination Mapping and Sun-Synchronous Path Planning in Lunar Polar Exploration Under Chang’E-7 Mission Constraints

The lunar south polar region’s extreme illumination conditions impose strict energy constraints for solar-powered rover operations. Traditional Sun-synchronous path planning relies on dynamic time-dependent illumination evaluation, leading to high computational costs. We present...

Tracking Variability in Atmospheric, Oceanic, and Riverine Inputs to the Iberian Margin Over the Last 250 kyr

Abstract The Iberian Margin provides an exceptional archive of climate variability due to its high sedimentation rates. However, uncertainties persist regarding the provenance of terrigenous detrital sediments on the Iberian Margin, and the climate‐driven changes in their source...

Integrative analysis of the embryonic origin of adult neural stem cells in forebrain subventricular zones

Abstract In the mammalian brain, adult neural stem cells (NSCs) located in ventricular-subventricular zone (V-SVZ) of lateral ventricles and dentate gyrus continuously generate new neurons and glia throughout life. The adult NSCs in V-SVZ are derived from ventricular radial glial...

Enhancing the performance of recycled rigid pavement coarse aggregate by mechanical–chemical synergistic treatment for lower-layer airport pavement concrete

To promote high-value reuse of decommissioned rigid pavements, a synergistic treatment for recycled rigid pavement coarse aggregate was developed and its suitability for airport pavement lower-layer concrete was evaluated. The treatment combined mechanical grinding with sodium si...

Estimated glucose disposal rate and incident cardiovascular disease across ageing cohorts in China, England, and the United States: cross-national consistency and transportability

The estimated glucose disposal rate (eGDR), an insulin-resistance surrogate derived from routine clinical variables, has been associated with cardiovascular disease (CVD). We examined its association with incident CVD, cross-national transportability, and incremental discriminati...

Evaluating Rate and Time Effects on Cyclically Loaded Offshore Foundations via a Bounding-Surface Viscoplastic Model

Abstract Offshore foundations are subjected to cyclic loading from waves, winds, and operations, and their response is inherently time-dependent and strongly influenced by loading rates due to the viscosity of clays. This study develops a simple yet theoretically robust framework...

Resilience Analysis of Shield Tunnel Segments and Overall Structure During Adjacent Undercrossing Construction Considering Varied Spatial Relationships

Abstract The disturbance effects induced by twin shield tunnel undercrossing significantly compromise the lining performance of existing tunnels and threaten operational safety. This study systematically evaluates lining resilience under cumulative disturbances and establishes a...

Chiral Nanostructured Cobalt Nanoparticles Confined in Zeolite for Syngas Conversion to Liquid Fuels at Low Temperature

ABSTRACT Low‐temperature Fischer–Tropsch synthesis is an energy‐efficient process that converts nonpetroleum carbon sources into liquid hydrocarbon fuels. However, achieving C─C coupling under mild conditions is a significant challenge, primary due to the high energy barriers ass...

Leukocyte glycemic index associated with 30-day mortality in sepsis patients with new-onset atrial fibrillation: insights from the MIMIC-IV database

This study aimed to examine whether the leukocyte glycemic index (LGI), a compact marker linking inflammatory burden with stress-related glucose disturbance, is associated with 30-day mortality among patients with sepsis complicated by new-onset atrial fibrillation (NOAF). This r...
