Diagnosing year-round ozone-relevant VOC reactivity under meteorological constraints in urban Beijing

Abstract Static volatile organic compound (VOC) rankings can identify abundant or reactive compounds, but their ozone relevance depends on the meteorological and photochemical state during ozone production. Here we combine yearlong hourly observations of speciated VOCs in urban B...

Shaking Table Test on Liquefaction of Sandy Soil Site and Sensitivity Analysis of Liquefaction Influencing Factors

Earthquake-induced soil liquefaction poses a severe threat to the structural safety of underground infrastructure. This paper presents a shaking table model test conducted on sand sites, where two site models—namely, uniform saturated sand and layered dry–saturated sand—are desig...

Dietary Fatty Acids, Cardiovascular Disease, and Life Expectancy Among Adults With Adverse Mental Health‐Related Characteristics: A Cohort‐Based Target Trial Emulation Study

ABSTRACT Adverse mental health‐related characteristics contribute to decreased life expectancy, largely driven by an elevated risk of cardiovascular disease (CVD). Dietary fatty acids influence disease occurrence and progression, yet the associations of polyunsaturated fatty acid...

PGMMF-Net: a POI-Guided Multi-modal Mamba Fusion Network for urban impervious surface extraction from optical and SAR imagery

Accurate extraction of urban impervious surfaces (IS) is essential for urban environmental analysis. However, optical-based methods are affected by shadows and spectral confusion, while optical-SAR fusion lacks urban functional semantics. Point-of-interest (POI) data provide comp...

Integrated Physiological and Multi-Omics Analysis Reveals Selenium-Mediated Drought Tolerance in Brassica napus Seedlings

Drought stress severely restricts early growth in Brassica napus, while selenium (Se) can enhance stress tolerance. This study examined how foliar sodium selenite pretreatment affects polyethylene glycol (PEG)-induced drought stress in B. napus seedlings. Seedlings were sprayed w...

From raw to cooked: The impact of cooking on bioaccessibility and health risks of toxic elements in leafy vegetables

Environmental policies in China have significantly reduced toxic element fluxes in soil and air, but slower declines in atmospheric toxic element flux have increased its relative contribution to crop contamination. Leafy vegetables, with their large surface area and high capacity...

Complete Mitogenomes of Three Hyphessobrycon (Characiformes, Characidae) Species and Phylogenetic Analysis of Characidae

Advances in biotechnological tools have accelerated the genomic characterization of non-model organisms, providing insights for broader bioprospecting efforts. In this context, Hyphessobrycon, one of the most species-rich and widely distributed genera in the family Characidae, re...

Integrating Land Use Change and Vegetation Resilience to Assess Ecological Impacts of Expressway Construction: A Case Study of the Linghua Expressway

The rapid expansion of road construction has significantly contributed to economic development and regional connectivity. However, linear infrastructure such as roads, railways, and utility corridors has also introduced considerable ecological disruptions. Although increasing glo...
