Entrepreneurship Educators’ Acceptance and Use of Generative Artificial Intelligence

Despite growing interest in generative artificial intelligence within entrepreneurship education, we lack theory-driven explanations of why or for what purpose entrepreneurship educators adopt these tools in their teaching practice. Addressing this gap, we refined understanding o...

Development and validation of a scale on exercise risk of university students

This study aims to develop a scale to assess exercise-related risk among university students and to evaluate its reliability and validity. The development of the scale was conducted in two stages. In the first stage, a preliminary version of the scale was formulated based on the...

Artificial neural network optimization of multifunctional wool dyeing with Hypericum scabrum using biomordant and metal biomordant binary systems

The growing demand for sustainable textile coloration has increased interest in natural dyes and eco-friendly mordanting strategies capable of imparting multifunctional properties. In this study, wool yarn was dyed with Hypericum scabrum extract under optimized conditions (pH 5,...

Dynamics of emotion-transition networks link brain network variability and affective symptoms

Emotion dynamics are closely linked to psychological health. Although inertia and variability have been linked to affective symptoms, relatively few studies have examined how emotional states are structurally organized and transition from one state to another. Using ecological mo...

Insula Grey Matter Volume Moderates the Relationship Between Emotional Intelligence and Domain‐Specific Creativity

ABSTRACT Emotional intelligence (EI) is linked to enhanced cognitive and social functioning, but its neurostructural correlates and relationship with domain‐specific creative achievement remain poorly understood. This study examined 266 young adults using the Emotional Intelligen...

The pregnancy vaginal microbiota exhibits alterations in association with gravidity, parity, and miscarriage history: a cohort study

Vaginal microbiota plays a critical role in reproductive health, yet the impact of woman’s obstetric history including gravidity, parity and miscarriage history, remains inadequately characterized. We conducted a cohort study to identify microbial biomarkers linked to these facto...

Spatial decoupling and structural fragility of China's grain system: Long-term evolution and pathways toward resilient reconstruction, 1990-2050

Climate-driven instability and the spatial mismatch between grain production and consumption pose growing threats to national food security. In response to this challenge, we developed a comprehensive evaluation system combining dynamic centroid analysis, optimisation model and e...

Bidirectional optoelectronic switching in protein by photoinduced phase transition

Protein polymers conduct electricity due to the delocalization of π electrons along the conjugated main chains, but their photoconductivity often shows unidirectional tunability. We report a protein polymer with bidirectional optoelectronic conductivity because of reversible ligh...

Multifunctional Defense of Achelura yunnanensis Cocoon: High-Strength Tough Silk Fiber, Biomineral Reinforcement, and Protease Degradation Resistance

Abstract Natural silks offer combinations of mechanical performance and biological functionality that synthetic materials still struggle to replicate. Here, we report the structural, mechanical, and biochemical characterization of cocoon silk from Achelura yunnanensis (Lepidopter...

Integrated Transcriptomic and Phytohormone Metabolomic Analyses Reveal Distinct Molecular States Associated with PSTVd-Induced Potato Tuber Cracking and Knob-like Protuberances at Tuber Eyes

Potato spindle tuber viroid (PSTVd) infection can induce tuber cracking and knob-like protuberances at tuber eyes, but the molecular differences between these two localized symptoms remain unclear. In this study, smooth surface regions and normal eye tissues were collected from m...

Ultrasound-Assisted Sustainable Extraction of Berberine from Coptis chinensis Franch. Using Temperature-Responsive Deep Eutectic Solvents

Abstract The development of deep eutectic solvents (DESs) that can be readily and sustainably recycled is expected to reduce costs and enhance the environmental friendliness of extracting plant-derived active ingredients. Here, a novel temperature-responsive DES prepared from pro...

Modulating task-outcome value to mitigate real-world procrastination via noninvasive brain stimulation

Procrastination is a prevalent behavioral problem associated with individual health and societal productivity. A leading model posits that procrastination reflects an imbalance between task aversiveness and the pursuit of positive task outcomes, yet this theoretical framework has...

A Sericin-Reinforced Poly(vinyl alcohol) Composite Hydrogel Integrating Sericin-Associated Silver Nanoparticles and Dual Growth Factors for Diabetic Wound Repair

Abstract Diabetic wound repair requires polymeric dressings that combine structural stability, swelling behavior, antibacterial activity, and biological support within a single material platform. Here, we report a sericin-reinforced poly(vinyl alcohol) (PVA) composite hydrogel in...

Cultural bias or universal traits? Exploring personality-like profiles of large language models

Abstract Do large language models (LLMs) exhibit coherent personality profiles, and are these profiles culturally neutral? This study used two validated personality inventories, the Big Five Inventory–2 and the Dark Triad Dirty Dozen, to assess five state-of-the-art LLMs (ChatGPT...

β3GnT2-mediated N-glycosylation of EGFR and LDLR drives glioblastoma progression and can be targeted by AST-1306

Abstract Glioblastoma (GBM) is the most aggressive primary brain tumor, characterized by a poor prognosis and limited therapeutic options. In this study, we identify β3GnT2 (β-1,3-N-acetylglucosaminyltransferase 2) as a critical driver of GBM progression and a potential therapeut...

Construction of a High-Efficiency Oxygen Evolution Reaction Catalyst Using V-Doped Synergistic Mott–Schottky Heterostructures

Abstract Rationally designing heterostructures with well-regulated electronic environments is desirable to circumvent the sluggish kinetics of the oxygen evolution reaction (OER). Herein, we propose a dual-engineering strategy─combining Fermi-level manipulation via heteroatom dop...

Pension Participation and Willingness to Increase Contribution Levels Among Rural Households in China: Evidence from the Chengdu–Chongqing Economic Circle

Against the background of China’s recent rural pension policy environment, this study uses in-person survey data from over 800 rural households in the Chengdu–Chongqing Economic Circle (CCEC) to examine two distinct outcomes: pension participation (current enrollment in the pensi...

Physical exercise frequency and subjective well-being among older adults in China: a cross-sectional analysis

Physical exercise is associated with subjective well-being in later life, but estimates from cross-sectional surveys require measurement-aligned models and cautious interpretation. We analyzed 1,872 adults aged 60 years or older from the 2021 Chinese General Social Survey. A five...

Genome-Wide Identification of the Maize ARR-B Gene Family and Expression Analysis Response to Low-Phosphorus in Maize (Zea mays L.)

Cytokinin signaling is essential for plant growth, development, and responses to environmental stresses. As key transcription factors in this pathway, type-B response regulators (ARR-Bs) activate the expression of primary cytokinin-responsive genes. However, the systematic identi...

Construction and Comparison of Molecular Identification Methods for Mannheimia haemolytica

Mannheimia haemolytica is a primary pathogen causing bacterial pneumonia in cattle and sheep. Multiple PCR targets exist for its identification, but no standardized primer pairs have been widely adopted. This study evaluated the universality of six reported primers (including rpt...
