The Impact of Industrial Clustering on Air Pollution in the Beijing–Tianjin–Hebei Urban Agglomeration: The Mechanism of Technological Innovation

As one of China’s most important industrial clusters, the Beijing–Tianjin–Hebei (BTH) urban agglomeration faces persistent air pollution while remaining a key driver of regional economic growth. In recent years, technological innovation has increasingly supported industrial upgra...

Heat as a Located Constraint on Grain Production in a Humid Basin: Implications for Climate-Adaptive Land Management

In humid agricultural regions, where heat and water deficit are decoupled, temperature acts on crops in two opposed ways: moderate warmth advances development, whereas extreme heat damages it, and land management must distinguish them. This study examined the temperature response...

Multiple organic acid-rich fermented wheat bran improves duck meat quality: insights from physicochemical, sensory, and metabolomic properties

Fermented feed improves nutrient digestibility and enhances beneficial microbial activity, leading to better animal growth and meat quality. The aim of this study was to investigate the effects of acid-rich fermented wheat bran GMAS2S3 supplementation on the meat quality and meta...

One‐Step Induction of Oogonia‐Like and Pro‐Spermatogonia‐Like Cells From Porcine Pluripotent Stem Cells

ABSTRACT Pigs share a germ cell regulatory network highly similar to that of humans, yet lack a robust system for inducing and expanding germ cells from pluripotent stem cells, impeding large‐animal gametogenesis research. Here, we established a modular platform capable of effici...

Effects of Different Ecological Restoration Treatments on Plant Functional Group Characteristics and Nitrogen and Phosphorus Stoichiometry in Alpine Semi-Humid Sandy Land

Ecological restoration of alpine sandy lands plays an important role in promoting vegetation recovery and enhancing ecosystem functions. However, the response characteristics of plant functional groups and nitrogen (N) and phosphorus (P) dynamics under different restoration treat...

Comparative Analysis of Fatty Acid Composition in Skeletal Muscles and Serum of Tianfu Goats

Fatty acid composition contributes to the nutritional characteristics of goat meat, but its variation among anatomical muscles remains insufficiently characterized. This exploratory study determined fatty acid profiles in six skeletal muscles and serum from nine 10-month-old cast...

Contrasting effects of ammonium and nitrate addition on soil organic carbon in Zoige Plateau peatland

Peatland soils, typically nitrogen (N)-limited, are important carbon (C) reservoirs and may be significantly affected by N deposition. Nitrate (NO 3 − -N) and ammonium (NH 4 + -N) are the primary forms of N deposition, with substantial spatial variability. However, how these N fo...

Facilitating residents’ storytelling in tourism communities: Communication infrastructure and acculturation

Storytelling has become an important means of destination branding, with residents as key creators and disseminators of local narratives. However, the structural and cultural conditions that enable residents' storytelling behavior remain insufficiently understood. Drawing on Comm...

Spermidine attenuates copper overload-induced cuproptosis in porcine granulosa cells through the miR-194a-5p/DLAT axis

Abstract Excess copper disrupts mitochondrial metabolism by triggering cuproptosis, a regulated cell-death program characterized by the aggregation of lipoylated tricarboxylic acid cycle proteins and the loss of Fe-S cluster proteins. This mitochondrial injury may be particularly...

Freeze–thaw-induced evolution of erosion mechanisms in cementitious materials under high-altitude environments

Concrete hydraulic structures in cold, high-altitude regions are subjected to coupled freeze–thaw deterioration and sediment-laden flows, leading to progressive surface degradation. However, the influence of freeze–thaw damage on the governing erosion mechanism remains poorly und...

Lattice Distortion‐Triggered Cu─O─Ce Synergistic Sites Coupled With Machine Learning for Intelligent Multi‐Pesticide Recognition

ABSTRACT Non‐enzymatic electrochemical sensors have emerged as highly promising platforms for pesticide monitoring, favored for their rapid response, cost‐effectiveness, and robust environmental stability. However, conventional sensors struggle with simultaneous multi‐target reco...

Differential regulation of physiological responses and selenium accumulation in blueberry seedlings under selenium stress by melatonin and the strigolactone

Abstract This study investigated the effects of exogenous melatonin (MT, 150 μ mol/L) and strigolactone analogue (GR24, 1 μmol/L) on the growth and selenium (Se) accumulation of ‘Farthing’ blueberry ( Vaccinium corymbosum L.) seedlings under Se stress (0.5 mg/L). Compared with th...

Flood damage estimation and disaster perception using multi-source data: a case study of Henan, China

Urban flood is becoming increasingly frequent worldwide, posing a serious threat to life and property. Accurately assessing flood damage is critical for risk management and flood prevention. However, traditional estimation methods are resource-intensive and untimely. Previous stu...

Contrasting rice-dryland crop rotation regimes drive divergent greenhouse gas emissions via labile organic carbon modulation, with trade-offs for crop yield

Context Optimizing crop rotations is essential for synergistically increasing yield and reducing environmental impacts. However, in rice-dryland crop rotation systems, the underlying mechanisms through which different dry-season crops influence subsequent rice yield and greenhous...

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...

Isometric training, conditioning and testing in relation to jump performance: a systematic review

Long-term isometric training, acute conditioning and isometric strength testing share a contraction mode but address different time scales and questions. We treated chronic training as the primary intervention question and the other domains as complementary evidence. The review f...

Dynamic Polyimine Resin Enables a Formaldehyde-Free, Remoldable, Degradable, and Closed-Loop Recyclable Wood-Based Composite

Abstract Conventional wood-based composites (WCs) were mainly manufactured by gluing woody biomass with formaldehyde-containing resin adhesives that have permanent covalent cross-links, making them harmful to human health and giving them poor remoldability, degradability, and rec...

Turning Livestock Waste into Nutrient Resources: Advances in Crop–Livestock Circular Agriculture for Sustainable Farming Systems

The increasing specialization of crop and livestock production has disrupted traditional nutrient cycling in agricultural systems, creating a dual challenge of excessive dependence on synthetic fertilizers and inefficient utilization of livestock manure. Crop–livestock circular a...

Seismic Resilience Evaluation of Double-Pier Bridge Substructures With Delay Time Consideration

Traditional bridges rely on ductile seismic design and hysteretic energy dissipation, followed by repairs to restore service. Double-pier bridge substructures are statically indeterminate; under transverse excitation, pier stresses hinder selecting damage indices, limiting seismi...
