Downscaling of SMAP Soil Moisture Based on the Transformer Algorithm in Anhui Province

Soil moisture (SM) is critical for climate, water, and agriculture, but Soil Moisture Active Passive (SMAP) passive microwave products have coarse resolution, limiting regional applications. This study develops an SM downscaling framework based on Transformer and its variants (Pa...

Trichinella spiralis galectin disrupts gut epithelial integrity and mediates larval invasion via acting MUC13- ROCK2/MAPK pathway

Background Gut epithelium serves as a critical barrier against Trichinella spiralis larval invasion, Parasite-derived galectins are involved in host–parasite interactions, including invasion and immune modulation. This study investigated the role of T. spiralis galectin (Tsgal) i...

The gut-ovary axis: how microbial players orchestrate female reproductive health

Ovarian dysfunction—encompassing polycystic ovary syndrome (PCOS), premature ovarian insufficiency (POI), and ovarian aging—poses a significant challenge in reproductive medicine, largely due to the limited availability of etiology-based treatments. Emerging evidence positions th...

Activating the Anomalous Jahn–Teller Effect in NASICON-Type Mixed Phosphate Cathode via Crystal Field Engineering

Abstract High-voltage Mn3+/Mn2+ redox reactions in polyanionic cathodes offer the potential to increase energy density while reducing the cost of batteries. However, its practical application is hindered by sluggish reaction kinetics and asymmetric Jahn–Teller distortion. Herein,...

Exploring Priority Intrapartum Services Associated with Childbirth Experience During Vaginal Birth: A Multicenter Cross-Sectional Study

Background: A woman’s childbirth experience is important to her health and family well-being. Evidence-based intrapartum care may support a positive experience. When resources are constrained, identifying services that are most strongly associated with childbirth experience may h...

Effects of Calcium Sulfate Whiskers and Basalt Fibers on Concrete Properties after High Temperature

Abstract Concrete structures serving in complex environments, represented by subsea tunnels, are deeply affected by high temperature and corrosive environments, and calcium sulfate whisker-basalt fiber reinforced concrete (CSW-BFRC) has the potential to match these environmental...

A boundary-guided strategy via pseudo-anomaly feature perception for unsupervised ECG signal quality assessment

Electrocardiogram (ECG) signal quality assessment is vital for ensuring accurate ECG diagnoses and efficient medical services. Traditional supervised ECG signal quality assessment methods are limited by a restricted set of noise categories, which results in poor generalization ab...

Investigating tunnel seepage erosion and induced structural mechanical response using CFD-DEM-FEM method

Seepage erosion, induced by groundwater infiltrating surrounding soils through cracks between tunnel segments, poses a significant threat to the long-term stability of underground tunnels. However, the evolution of erosion and its influence on tunnel mechanical behavior remain in...

A DNA methylation-based machine learning model for early and accurate diagnosis of cervical HSIL+ lesions

Abstract Current cervical cancer screening methods lack accuracy in early diagnosis and risk prediction. We developed a DNA methylation-based diagnostic model for cervical high-grade squamous intraepithelial lesions or more severe lesions (HSIL+). This study systematically collec...

Polymer-Ionic Liquid-TiO2 Composite Electrolyte for Safe and High-Voltage Lithium Metal Batteries

Abstract Lithium metal batteries (LMBs) are promising next-generation energy storage systems. However, their practical application remains limited by safety concerns and poor compatibility with high-voltage cathodes, arising from interfacial instability, dendrite growth, and unev...

Upcycling Spent Tea Leaves into a Multifunctional Separator for High-Performance and Eco-Friendly Aqueous Zinc-Ion Batteries

Abstract Aqueous zinc-ion batteries (AZIBs) suffer severe limitations from uncontrollable Zn dendrite growth and parasitic side reactions. Separator functionalization is a promising strategy for addressing these challenges. However, modifying cellulose-based separators often invo...

Hybrid deep learning framework for AI-generated text detection

Recently, large language models have demonstrated remarkable ability to generate human-like textual content. This advancement has increased the need for reliable methods to detect AI-generated texts, particularly to address concerns related to academic dishonesty and the spread o...

Human metapneumovirus in central China, 2024–2025: epidemiology, co-infections, and temporal dynamics

Human metapneumovirus (HMPV) is a major cause of acute respiratory infections in children, but comprehensive data from sentinel surveillance in the post‑pandemic period remain limited. Understanding its epidemiology and co‑infection patterns is critical for surveillance and preve...

Multiomics profiling identifies molecular and cellular signatures of regular exercise in human peripheral blood
