Elevated aerosol layers within the daytime mixed layer over ecologically sensitive areas of northwest China: diurnal variation, formation mechanisms and regional effects

Abstract. The cyclic processes of aerosol evolution have a profound impact on regional climate, water resources and ecosystems. However, studies on diurnal variations of aerosol vertical distribution in typical ecologically sensitive areas remain scarce due to limited availabilit...

Planetary Boundary Layer Height on the Northern Mount Qomolangma Region Retrieved From Wind LiDAR Observations

Abstract A coherent Doppler wind LiDAR (Wind3D 6000) has been operating in the northern Mount Qomolangma region since 2023. We retrieved planetary boundary layer height (PBLH) from LiDAR observations collected from October 2023 to September 2025 using a hybrid algorithm combining...

Design and Optimization of Composite Thermal Insulation Layers for Mine Ecological Restoration Under Simulated Solar Radiation: Integrating Response Surface Screening with Gaussian Process Bayesian Optimization

Thermal regulation of surface soil is critical for vegetation establishment in degraded mining environments, yet the systematic design of insulation layers tailored to mine restoration remains underdeveloped. Fifteen candidate thermal insulation materials from six categories were...

Self‐Growing Conductive Hydrogels Establish Volumetric Biointerfaces for Cardiac Conduction Restoration

ABSTRACT Restoring three‐dimensional electrical conduction in infarcted myocardium remains a critical challenge, as conventional conductive hydrogel patches largely remain surface‐confined and prevent electrical coupling of residual cardiomyocytes within fibrotic scars. Here, we...

Charge Separation Engineering via ZnCdS/CoNiPPc Schottky Heterojunction to Achieve Efficient Photocatalytic Hydrogen Evolution Coupled with Benzaldehyde Production

To address common challenges in photocatalytic water splitting for hydrogen (H 2 ) production, such as slow hole consumption kinetics and uncontrolled oxidative side reactions, we have designed an innovative Zn 0.5 Cd 0.5 S/bimetallic cobalt/nickel polyphthalocyanine (denoted as...

ASFV D117L hijacks KEAP1 to induce oxidative stress-dependent vascular endothelial cell death

African swine fever (ASF), caused by the ASF virus (ASFV), is a fatal hemorrhagic disease of domestic pigs that causes significant economic losses in the global pig industry. Systemic hemorrhages and abnormal coagulation of multiple tissues and organs are the typical lesions of A...

Pan-retinal pathology detection in oct scans integrating natural language synthesis with diagnostic annotation

Abstract While OCT is pivotal for macular disease diagnosis, its adoption in primary care is limited by AI systems that cannot simultaneously analyze multi-sectional scans across the full spectrum of maculopathies or generate diagnostically integrated reports. Here we present iOC...

Cation‐Engineered Narrow‐Band Green Emitting Phosphor Toward High‐Performance Laser‐Driven Displays

ABSTRACT Wide color gamut and high brightness are critical performance metrics for advanced displays like projectors. Combining narrow‐band green and red color converters with a blue laser‐driven light source is one of the most effective solutions to achieve these goals. In this...

The Shape-SelectiveSuspension–Deposition Differentiationof Microplastics in an Air–Snow System: Insights from a NortheasternPolluted City in China

Abstract Atmospheric microplastics (MPs) are increasingly recognized as important atmospheric pollutants, yet the role of particle physical properties in their suspension–deposition differentiation remains unclear. Here, MPs were simultaneously investigated in 31 total-suspended-...

Optimal FBG Sensor Layout Assessment for Accurate Structural Feature Recognition of Composite Plates

Carbon fiber-reinforced polymer (CFRP) composites are increasingly used in aerospace, rail transportation, and energy engineering owing to their high specific strength and corrosion resistance. However, their complex and interacting damage mechanisms, including delamination and m...

Causal association between air pollution and functional outcome after ischemic stroke: Evidence from 2-sample MR study

Observational studies have shown that air pollution may affect functional outcome following ischemic stroke. Our study aimed to explore the relationship between genetically predicted specific air pollutants and poststroke functional outcomes using the Mendelian randomization (MR)...

Evaluation of the Impact of Aged Biomass Burning Emissions on the Global Ozone From the Surface to the Lower Stratosphere

Abstract Biomass burning (BB) is a major global sources of ozone (O 3 ) precursors, including nitrogen oxides (NO x ), carbon monoxide (CO), and volatile organic compounds (VOCs). Here, we combine Community Earth System Model 1 with airborne measurements from the NASA Atmospheric...

Stage-aligned electro-ionic biobattery hydrogel for enhanced wound closure and scar reduction

Coupling electrical stimulation (ES) with biochemical signaling is attractive for coordinating multi-stage wound healing, yet existing biobatteries rarely deliver stable microcurrents with stage-aligned chemical therapy in a scalable format. Here, we report a 3D-printed zinc-iron...

Baseline Response Characterization and Relative Vertical Displacement Reconstruction of Multi-Layer Asphalt Pavements Based on Quasi-Distributed FBG Monitoring Information

Internal responses of multilayer pavement structures are difficult to characterize using surface-based inspection alone. This study investigates a scaled multilayer pavement model instrumented with embedded quasi-distributed fiber Bragg grating (FBG) sensing lines to obtain basel...
