Breaking the dilemma of trajectory imbalance and sample scarcity: A Multi-Behavior Prototype Siamese Network for vessel type recognition

Vessel type recognition is at the core of intelligent maritime monitoring. Real-world AIS datasets follow a long-tailed distribution, giving rise to two coupled challenges: class imbalance and sample scarcity in minority vessel categories. Samples from majority classes dominate t...

Coupling refining and modification effects of Sr, Mn, and Al-V-Ti-B on microstructure of Al-7Si-0.25Fe alloy

Al-Si alloys are widely used in aerospace and automotive industries due to their high specific strength and low cost. Their mechanical performance is closely related to the grain size of the α-Al matrix and the morphologies of secondary phases such as eutectic Si and Fe-containin...

Gap-tuned exceptional skin effect in non-Hermitian flat bands

Flat-band states in Hermitian systems exhibit compact localization in the bulk due to geometric or symmetry constraints, while non-Hermitian skin effects drive state accumulation at boundaries via asymmetric lattice hoppings. Despite extensive efforts devoted to studying these tw...

Lewis Acid Catalyzed Solvent Switching Enabled Diastereodivergent Hydroimination of Bicyclo[1.1.0]butanes

Abstract A Lewis acid catalyzed, solvent-switching diastereodivergent hydroimination of acyl bicyclo[1.1.0]butanes with diphenylmethanimine is reported. Using a rhodium Lewis acid catalyst, the reaction proceeds with excellent and predictable diastereocontrol simply by changing t...

Contradictions, Conflicts and Helplessness: Contemporary Chinese Mothers' Parenting Experiences—A Qualitative Study

ABSTRACT Grounded in the context of rapid social transition, this study investigates Chinese maternal parenting experiences through an analysis of concrete parenting practices. Drawing on one‐on‐one in‐depth interviews with 14 Chinese mothers of middle school students and subsequ...

Handgrip Strength and Early Screening of Alzheimer’s Disease: Current Evidence and Emerging Role of Artificial Intelligence

Alzheimer’s disease (AD) is the most prevalent progressive neurodegenerative disorder in older adults, marked by insidious cognitive decline and gradual loss of functional independence. Growing evidence suggests that handgrip strength (HGS) assessment may provide a simple, noninv...

Digital Industry Cluster Policy and Corporate ESG Performance: Evidence from China’s Innovative Industrial Cluster Program

We examine whether digital industry cluster policy is associated with corporate environmental, social, and governance (ESG) performance. We study digital industry clusters within China’s Innovative Industrial Cluster program, a spatial industrial policy combining cluster designat...

Piezoelectric and Pyroelectric Materials in Advanced Biomedical Applications: Multifunctional Integration and Clinical Prospects

ABSTRACT Piezoelectric and pyroelectric materials are advancing a broad spectrum of biomedical technologies, the former interconverting mechanical and electrical energy and the latter converting thermal fluctuations into electrical signals. For biosensing and health monitoring, p...

Seasonal wet–dry transitions reveal contrasting microbial stability and nutrient cycling across floodplain lake habitats

Abstract Saucer-shaped sub-lakes in floodplains undergo strong seasonal changes in water level and connectivity, but their microbial responses and roles in nutrient cycling remain poorly understood. Here we show, using 28 lake units across Lake Poyang, China, that seasonal hydrol...

Is there cultural planning in China? Planning for cultural facilities as a governance mechanism in the Pearl River Delta

Cultural planning is generally understood as a participatory, place-based planning paradigm emphasizing cross-sectoral collaboration, public participation, and the integration of cultural, social, and spatial objectives. Its applicability beyond these institutional contexts remai...

Association between physical fitness index and executive function in Chinese Tibetan adolescents aged 10–12

OBJECTIVE: Examine the associations between Physical Fitness Index (PFI) and specific executive function (EF) subdomains (inhibitory control, working memory, cognitive flexibility) among Tibetan adolescents aged 10-12 years in China's high-altitude areas. METHODS: A total of 376...

Wave dynamics of Data-Driven soliton interaction for the nonlinear Bubble liquid model in complex fluid systems using Symbolic based Artificial Neural Network approach

In this article, we investigate the wave dynamics for solitons to the nonlinear bubble liquid model by applying the novel bilinear neural network approach. This equation has applications in complex fluid systems, fluid mechanics, geophysical flows, acoustic activation, and biomed...

Analysis of the contraction performance of the bending contraction artificial muscle actuated by negative pressure

Artificial muscle is a kind of common soft driver. Among them, the ones actuated by negative pressure have some advantages in comparison with those actuated by positive pressure, such as naturally limited output force and greater safety. This paper has designed a bending contract...

Ultrahigh On/Off Ratio Oxide Transistors via Noncoplanar Schottky–Ohmic Contacts

Abstract Simultaneously balancing high mobility and ultra-low leakage current is a major challenge for metal-oxide thin-film transistors (TFTs) in ultra-low-power applications. Herein, we construct a high-performance InGaZnO/InGaO/InGaZnO tri-layer TFT based on a noncoplanar Scho...
