Optimizing urban green spaces to enhance cooling intensity and heat resistance across thermal comfort gradients

Enhancing the cooling intensity (CI) and heat resistance (HR) of urban green spaces (UGS) is crucial for improving urban thermal comfort. However, the cooling effect of these UGS is usually evaluated under a single temperature condition, which may overlook whether the cooling eff...

Physics-guided data-driven learning with active learning for slope stability analysis considering spatial variability

The spatial variability of soil properties significantly affects slope stability and failure mechanisms, introducing uncertainties in the factor of safety ( F s ), deformation responses, and critical slip surfaces (CSS). Traditional Monte Carlo-based random field methods are comp...

Soil-structure interaction effects on the static disproportionate failure resistance of reinforced concrete frames: A staged numerical study using finite-element and finite-difference methods

The present numerical investigation evaluates how Soil Structure Interaction (SSI) affects the static Disproportionate Failure (DF) behavior of Reinforced Concrete (RC) frames subjected to localized column removal. The numerical framework uses Finite Element (FE) modeling in Seis...

The Impact of Industrial Clustering on Air Pollution in the Beijing–Tianjin–Hebei Urban Agglomeration: The Mechanism of Technological Innovation

As one of China’s most important industrial clusters, the Beijing–Tianjin–Hebei (BTH) urban agglomeration faces persistent air pollution while remaining a key driver of regional economic growth. In recent years, technological innovation has increasingly supported industrial upgra...

Modeling Offshore Fire Impact Induced by Subsea Hydrogen Releases

Abstract Offshore hydrogen production has developed rapidly in recent years. Accidental hydrogen releases in offshore environments threaten the safety of hydrogen supply chain. A mathematical model of sea-surface fire induced by subsea hydrogen release is developed using computat...

Cold-adapted membrane-aerated biofilm reactor for domestic wastewater treatment in northwest China: Pollutant removal performance and mechanistic insights

Membrane-aerated biofilm reactors (MABRs) have considerable potential for carbon and nitrogen removal from domestic wastewater. However, their long-term performance under high-altitude, low-temperature, and low-C/N conditions remains insufficiently understood. In this study, a pi...

Effect of spray temperature on microstructure and corrosion resistance of cold-sprayed zinc coatings

Pure zinc (Zn) coatings were prepared on gray cast iron surfaces by cold spray (CS) to improve their corrosion resistance. The effects of spray temperature on deposition behavior, microstructural characteristics and corrosion performance of Zn coatings were investigated. Higher g...

Prediction of Mechanical Strength of AALRS under Extreme Lunar Environments: An Interpretable Stacking Ensemble Model Integrated with Hyperparameter Optimization Algorithms

Abstract Alkali-activated lunar regolith is a promising extraterrestrial material for large-scale construction of lunar bases. However, the complex coupling effects of multiple influencing factors present significant challenges to strength prediction and mechanistic interpretatio...

Natural thickness redistribution and axial buckling of non-geodesic continuous variable-angle filament-wound composite tubes

The development of deepwater and offshore engineering has imposed increasingly stringent requirements on the axial-compression stability and load-carrying efficiency of lightweight composite tubular structures. Although continuous variable-angle filament winding enables spatial t...

Hazard assessment of spontaneous plants based on plant diversity: A case study of the Jiahu Archaeological Site, China

This study fills a long-standing research gap in systematic vegetation hazard assessment for Chinese archaeological sites, a field previously dominated by Mediterranean-focused cases. Taking the Jiahu Archaeological Site in Henan as the research object, it explores the correlatio...

Experimental and numerical study on seismic performance of beam-column rigid joints with embedded transition columns in steel archaized buildings

Steel archaized buildings (SABs) commonly use transition columns connecting upper square and lower circular steel tubes. The abrupt sectional change can cause stress concentration and stiffness discontinuity along the column height, yet the influence of embedment in these all-ste...

Assessing architectural interventions in rock-cut heritage: a resilience-based restoration approach at Longmen Grottoes, China

The loss of protective structures exposes cave temples to climatic disturbances, but the environmental effects of their restoration remain insufficiently quantified. This study develops an environmental-resilience-oriented restoration framework integrating historical reconstructi...

Techno-economic assessment of the deployment potential of solar district heating in high solar radiation plateau regions

Solar district heating is a promising low-carbon heating option for high-altitude Xizang, yet county-level assessment methods that simultaneously account for collector-field siting constraints and techno-economic performance remain lacking. This study develops an integrated count...

Seismic performance and flexural bearing capacity of UHPC prefabricated reinforcement cage formwork concrete column-RC ring beam joints

Existing research on ring beam joints is mostly limited to the concrete-filled steel tube (CFST) column system, which has inherent deficiencies in fire resistance and durability. To address this issue, the present study proposes a novel structural configuration that applies ultra...

Experimental analysis and evaluation of a new seismic isolation method for subway stations in the Loess Plateau with localized sand-interlayered strata

Abstract Post-earthquake statistics indicate that the existing seismic measures and evaluation methods for subway stations in the Loess Plateau with locally interbedded sand layers are inadequate. During earthquakes, the station roofs are prone to deformation or even failure, pos...

AMET-YOLO: A Pear Leaf Disease and Pest Detection Model Integrating Multi-Strategy Feature Enhancement and Task Alignment
