The Impact of High-Temperature and High-Pressure Steaming Treatment on Bioactive Compounds and Antioxidant Activity in American Ginseng

Thermal processing facilitates the transformation of major ginsenosides into rare ginsenosides, thereby enhancing the bioactive molecular profile of American ginseng. This study examined the impact of 1–4 cycles of high-temperature and high-pressure steaming (HTHPS) on ginsenosid...

From iron to sugar: How aerated drip irrigation increases soluble sugar content in citrus fruit through soil microbial communities

Root-zone hypoxia is common in citrus orchards on red soils and limits sugar accumulation in fruit. Aerated drip irrigation (ADI) may improve the soil redox environment, but whether it regulates fruit soluble sugar through microbially driven iron transformation is unclear. A fiel...

Enhancing Coastal Safety with AI: A Lightweight Deep Learning Framework for Rip Current Segmentation via Architectural Co-Design and Model Compression

Rip currents pose significant threats to coastal safety and to autonomous marine vehicles operating nearshore. However, deploying high-precision monitoring models on resource-limited platforms remains challenging. This paper proposes a comprehensive framework that combines a nove...

Biomechanical analysis of lower limb asymmetry in elite junior male Tai Chi athletes: associations with stomping technique performance

Abstract Long-term unilateral dominant training in Tai Chi is commonly associated with lower-limb functional asymmetry in elite athletes, which may correlate with reduced movement proficiency and increased injury susceptibility. This study recruited 80 elite junior male Tai Chi a...

Compatibility of Low‐Dimensional Perovskites in n–i–p and p–i–n Perovskite Solar Cells

ABSTRACT Low‐dimensional (LD) perovskites have emerged as a cornerstone strategy for mitigating the intrinsic instability and suppressing interfacial non‐radiative recombination in 3D perovskites. Nevertheless, the intrinsic charge transport anisotropy of LD phases fundamentally...

AI-mediated informal digital learning of English in Kazakhstan and Uzbekistan: The roles of L2 motivational selves and learner resilience

The rapid development of generative artificial intelligence (AI) has reshaped informal digital learning, yet most research has focused on well-resourced contexts and often treats AI-mediated learning as a standalone phenomenon. This leaves a limited understanding of how learners...

Numerical investigation of dynamic characteristics of water entry of a wedge constrained by an ice floe

The water entry of a wedge is a canonical model for studying hull-slamming dynamics. However, existing studies have not considered the combined effects of the three-degree-of-freedom (3-DOF) motion of a nearby ice floe and hydroelasticity. This study aims to elucidate the dynamic...

Plastisphere microbial succession and predicted functional responses: a 60-day temporal study in wastewater effluent

Abstract Although wastewater treatment plants (WWTPs) achieve high microplastic removal efficiency, substantial quantities are still discharged, and the long-term dynamics of plastisphere microorganisms on their surfaces and potential impacts on receiving waters remain poorly und...

The association between physical exercise participation and individual-level relative health deprivation varies by age, period, birth cohort, and population group in China

Abstract Health inequality remains a key concern in public health policy. In this study, health inequality provides the broader public policy context, while individual-level relative health deprivation serves as the empirical outcome and is measured using the Kakwani relative dep...

Research on the integration method of power transfer and data communication based on LCL resonant topology

To address the limitations of traditional Power Line Carrier (PLC) communication, which can only transmit weak signals and struggles to balance high-power supply in strong interference environments, this paper proposes a power and signal integration method based on an LCL resonan...

Upcycling Waste Fruit Bags into Hierarchical Porous Carbon for High-Performance Zinc-Ion Hybrid Supercapacitors

Abstract The rational design of hierarchical porous heteroatom-doped carbon is critical for advancing the practical application of zinc-ion hybrid supercapacitors (ZIHSs). Herein, we propose a sustainable upcycling strategy to convert waste fruit bags into N/O-codoped porous carb...

Genome-Wide Identification and Expression Pattern Analysis of the DXS Gene Family in Eucommia ulmoides

1-deoxy-D-xylulose-5-phosphate synthase (DXS) is the first key enzyme in the methylerythritol phosphate (MEP) pathway of plant terpenoid biosynthesis, and it plays a vital role in Eucommia ulmoides terpenoid biosynthesis. In this study, bioinformatics methods were used to compreh...

Bridging Nano-Interface Interactions and Organ-Specific Toxicity: A Review of Machine Learning for Nanomaterials Risk Assessment

Risk assessment of engineered nanomaterials (ENMs) is essential for protecting human health and the environment. Traditional hazard assessments rely primarily on in vivo testing, which faces technical challenges in extrapolation validity, ethical dilemmas, and high costs. Machine...

Portable-Equipment-Assisted Colorimetric Hydrogel Kits Based on Quercetin-Reducing Silver Nanoparticles for Hg2+ Tests in Aquatic Products

Abstract As a highly hazardous heavy metal, mercury ion (Hg2+) poses a serious threat to human health through the intake of polluted aquatic products and water. Accordingly, the development of a simple, sensitive, and efficient method for Hg2+ detection is of significant importan...

A self-supervised multi-task framework for downhole fault diagnosis in oil fields: Enhancing temporal feature learning under limited labels
