Structural and configurational analyses of GenAI-mediated informal digital learning of Chinese, multicultural personality traits, and willingness to communicate: evidence from plurilingual international students in China

This study examines how plurilingual international students’ generative AI-mediated informal digital learning of Chinese (GenAI-IDLC) interacts with dimensions of multicultural personality to predict their second language willingness to communicate (L2 WTC). Survey responses were...

Probiotic Characteristics and Whole-Genome Profiling of Lactiplantibacillus plantarum V2 Isolated from Tibetan Plateau Traditional Yogurt

Lactiplantibacillus plantarum V2 is a probiotic strain isolated from yogurt by Tibetan Plateau herdsmen in China. In this study, we systematically evaluated the probiotic potential and genome-wide features of L. plantarum V2. The cell-free supernatants (CFSs) of strain V2 exhibit...

Evaluation for Optimal Model Selection and Bias-Corrected Projections of Daytime and Nighttime Extreme Heat in China Using the SimmEX Dataset

Global warming has intensified extreme heat events, posing growing climate risks. As a climate-sensitive region, China has experienced compound daytime and nighttime extreme heat, threatening health, ecosystems, and socioeconomic development. Accurate projections of future extrem...

KLDD: Underwater image enhancement via KL-divergence-driven color cast correction and multistage enhancement fusion

Underwater images often suffer from severe color casts, nonuniform illumination, reduced contrast, and blurred details because of wavelength-dependent absorption and light scattering. To address these degradations, this study proposes KLDD, an underwater image enhancement method...

The Impact of Agricultural Digitization on Green Total Factor Productivity in Agriculture: Evidence from 30 Provinces in China

Amid tighter resource and environmental limits in China, the integration of digitization and greening gives new momentum to sustainable agriculture; however, its methods and structural conditions remain unclear. This study utilizes provincial panel data from 2011–2023 and the sup...

Optimal Dietary Vitamin A Fortification Improves Growth Performance, Nutrient Metabolism, Antioxidant Capacity, Immune Response, and Histomorphology in Intensively Cultured Litopenaeus vannamei

Vitamin A (VA) functions as a vital micronutrient supporting growth, immune competence, and stress tolerance in shrimp, though its requirement under industrial high-density rearing conditions has not been established. This study assessed how graded dietary VA levels affect growth...

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement

ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid ap...

Landmark-aware visual localization for GNSS-denied UAV wind farm inspection via lifecycle binding and adaptive fusion

Abstract This paper proposes a lightweight landmark-aware visual localization framework intended as a backup localization subsystem for UAV inspection in GNSS-denied wind farms. The system utilizes wind turbine towers as natural semantic beacons and integrates YOLOv12s and BoT-SO...

Enhancing underwater image clarity: a multi-branch network with commonality-specificity fusion

Underwater images often suffer from degradation due to light attenuation and scattering, posing challenges for vision-based tasks. This paper introduces a novel Edge-Guided Multi-Branch Commonality-Specificity Network (EGMCS-Net) to enhance underwater image quality. The network i...

Fucus vesiculosus-Derived Fucoidan Mitigates Recognition Memory Deficits in Association with Modulation of the Microbiota–Gut–Brain Axis in Adenine-Induced Chronic Kidney Disease Mice
