Revealing the diurnal spatiotemporal dynamics and drivers of urban traffic congestion resilience

Urban traffic congestion imposes recurrent stress on urban transport systems and varies substantially across the day. This study conceptualises urban traffic congestion resilience (UTCR) as an hourly proxy state under recurrent congestion conditions and develops an integrated roa...

Parameter determination method for model of ZnO varistors based on dynamic V-I characteristics

This study investigates the dynamic volt-ampere characteristics and residual voltage responses of ZnO varistor of five different sizes under various impulse waveforms, including 8/20 μs lightning current, 30/80 μs operating wave, 1/5 μs steep wave, and 2 ms square wave impulses....

Satellite altimetry reveals heterogeneity in global flood peak timing and its shifts

Flood peak timing (FloPT) is a key indicator of hydrological responses to climate change. Yet global FloPT assessments is limited by sparse and uneven in-situ discharge observations. Here, we demonstrated the capability of satellite altimetry to estimate FloPT worldwide and prese...

Water-oil interfacial kinetics control enables water-based organic solar cells with 12.59% certified efficiency

Organic solar cells (OSCs) are promising for clean-energy generation, but sustainable production remains constrained by hazardous organic solvents. Aqueous organic-semiconductor nanoparticle (NP) inks offer an environmentally friendly route to OSCs, yet low efficiency and limited...

Overweight and obesity in China: a growing economic burden

The rising prevalence of overweight and obesity (OAO) over recent decades has imposed substantial health and economic burden worldwide. OAO is a well-established modifiable risk factor that increases population risk of multiple chronic associated complications, and this study qua...

Actin‐Related Causes of Aneuploidy in Human Eggs

Gametogenesis (oogenesis and spermatogenesis) relies on a specialized form of cell division known as meiosis. During this process, chromosomes in parental cells undergo two successive rounds of segregation, resulting in a halving of their number and the formation of haploid germ...

Predictive value of triglycerides-total cholesterol-body weight Index for postoperative complications in elderly patients undergoing coronary artery bypass grafting

Triglycerides-total Cholesterol-Body weight Index (TCBI, calculated as triglycerides × total cholesterol × body weight / 1000), as a novel nutritional index, was closely associated with prognosis of patients with heart failure and aortic dissection. However, there are no studies...

Intercropping enhances spatial photosynthetic efficiency through stomatal and anatomical adaptations in rapeseed–vetch systems

Contexts Enhancement of leaf photosynthetic capacity and complementary canopy light distribution arising from species diversity are fundamental for biomass accumulation in forage intercropping systems. However, the mechanisms by which intercropping alters the spatial distribution...

A 2D MPLBM-FDEM method for modeling two-phase displacement in porous media under fluid-solid interaction conditions

This paper develops a two-dimensional (2D) numerical framework by coupling the multi-component pseudopotential lattice Boltzmann method (MPLBM) and the combined finite-discrete element method (FDEM) to investigate the process of two-phase displacement in porous media under fluid–...

Artificial intelligence-based assessment of gastric mucosal exposure and its association with lesion detection: a multicenter study

Completely and clearly visualizing the mucosa during esophagogastroduodenoscopy (EGD) improves high-risk lesion detection. Here we propose a new EGD quality control indicator and present the optimal gastric mucosal exposure area (OGMEA) system to automatically assess mucosal expo...

Polarization-enhanced ultrafast carrier transfer dynamics in Ga2O3/WS2 heterojunctions

Polarization engineering offers a promising strategy to enhance photogenerated carrier separation in van der Waals heterojunctions. Herein, the mechanisms governing polarization-enhanced carrier separation in Ga2O3/WS2 are investigated using nonadiabatic molecular dynamics. The r...

Experimental Study on Transient Hydraulic and Heat Transfer Characteristics of Granite Fractures under Thermo-Hydro-Mechanical-Chemical Coupling

The hydraulic and heat transfer evolution of granite fractures under thermo-hydro-mechano-chemical coupling represent a pivotal challenge for the sustainable and stable operation of Enhanced Geothermal Systems. In this study, transient fracture flow and heat transfer experiments...

EREAL: Enhancing Mathematical Reasoning through Error-Aware Learning in Large Language Models

Large Language Models (LLMs) have achieved substantial progress in solving complex mathematical problems, yet they often fail to exploit the potential value embedded in their own mistakes. Existing methods either apply coarse-grained corrections or rely on costly self-reflection,...

An Interpretable XGBoost-SHAP framework for rapid regional assessment of liquefaction-induced lateral spreading in mildly sloping ground

Liquefaction-induced lateral spreading poses significant risks to infrastructure on mildly sloping ground during earthquakes. This study develops an interpretable machine learning (ML) framework for rapid regional-scale prediction of liquefaction-induced displacement using an Ext...

Temperature and emissivity retrieval from ground-based thermal infrared hyperspectral imagery of open scene

Since the measured radiance in ground-based thermal infrared hyperspectral imagery of open scenes is simultaneously influenced by target surface emission, atmospheric path emission, and environment-reflected radiance, accurately retrieving surface temperature and emissivity for c...

Few-Shot Remote Sensing Scene Classification Leveraging Collaboration of Foundation Models

Foundation models have shown remarkable generalization ability for few-shot learning (FSL). However, their potential for remote sensing scene classification has not been fully explored. Existing methods mainly adapt a single vision–language model and seldom exploit the complement...

Salt-marsh aboveground biomass estimation by integrating UAV LiDAR-derived canopy height and Sentinel-1/2 satellite data
