Geometry-Guided Semi-Supervised Multimodal Segmentation for UAV-Based Rice-Lodging Mapping

Accurate rice-lodging mapping from unmanned aerial vehicle (UAV) imagery supports post-disaster loss assessment, crop insurance, and precision field management. Existing deep-learning methods typically require dense pixel-level annotations, which are costly and time-consuming to...

The impact of eco-compensation policies on the ecological product value realization rate in compensated areas

Abstract The realization of ecological product value serves as a vital link between socioeconomic development and environmental resources. A high ecological product value realization rate effectively captures the synergy between economic growth and ecological conservation, ultima...

Conservation gaps, taxon-specific mechanisms, and synergistic benefits of amphibian-centered planning in a karst biodiversity hotspot

Habitat loss, climate change, and disease are driving global amphibian declines, making amphibians valuable indicators for conservation assessment. We integrated field surveys (2013–2025) covering 120 amphibian species in Guizhou, a karst biodiversity hotspot, with species distri...

Cumulative spatial assessment of observed wildlife-vehicle collisions based on indicator species thresholds

Global road network expansion has exacerbated wildlife-vehicle collisions. However, traditional risk assessments predominantly assume a linear relationship between landscape features and observed collision quantities, overlooking the non-linear threshold characteristics of ecolog...

Effects of a Waterborne Coating on the Moisture Response, Surface-Layer Structure, and Mechanical Properties of Inorganic-Bonded Bamboo Composite

Inorganic-bonded bamboo composite (InorgBam) combines the lightweight, high-strength nature of bamboo bundles with the heat resistance, low smoke emission, and environmental compatibility of inorganic binders. However, the inherent surface pores and inter-bundle gaps in this mate...

Wood Skeleton Supported Anisotropic Ionic Thermoelectric Hydrogels for Efficient Low‐Grade Heat Harvesting

ABSTRACT Ionic thermoelectric hydrogels show great potential for wearable electronics and low‐power energy harvesting. Achieving high ionic conductivity, large Seebeck effect, mechanical robustness, and environmental stability simultaneously remains challenging. Inspired by natur...

Unveiling the Lubrication Mechanism of Graphene Coating on PEEK: A Molecular Dynamics Study Under Dry Friction and Seawater

Graphene coatings have considerable potential to improve the tribological performance of polyetheretherketone (PEEK) under dry friction conditions. For PEEK components operating in marine environments, direct exposure to seawater introduces water molecules and dissolved ions into...

Females cooperate, rather than monopolize reproduction, in multi-female groups of cooperatively breeding birds and mammals

Abstract Scholars have long sought to understand why, in some cooperatively breeding species, females care for the offspring of other group members while forgoing their own reproduction. Here, we analysed data from 101 cooperatively breeding populations of 73 bird and mammal spec...

Jasmonic acid signaling in plants: regulatory mechanisms in development and stress responses

Jasmonic acid (JA), one of the most pivotal plant hormones, has emerged as a central focus in plant biology research due to its extensive and diverse biological functions. This review synthesizes the significant advancements made over the past decade in understanding JA’s role in...

Biocatalytic Production of Piceatannol-4′-O-Glucoside Using a Novel Glycosyltransferase SoUGT from Saponaria officinalis

Abstract Piceatannol is a natural stilbene polyphenol with promising bioactivities, but its poor water solubility and low bioavailability limit industrial applications. In this study, a novel UDP-dependent glycosyltransferase, SoUGT, was identified from Saponaria officinalis for...

The effect of cracks on mechanical properties of round bamboo

Abstract Cracks are inevitable defects in engineering applications of round bamboo. However, existing research on the effects of cracks on the mechanical properties remains insufficient. In this study, systematic mechanical tests were conducted on crack-free (B1) and cracked (B2)...

A Six-Degree-of-Freedom Wave Compensation Parallel Robot with Triple-Loop Fractional-Order PI Control Optimized by Tuna Swarm Optimization

For high-precision attitude adjustment tasks of a six-degree-of-freedom (6-DOF) wave-compensation parallel robot in shipborne applications, strong non-stationary wave excitations, abrupt load changes, and broadband disturbances jointly challenge tracking accuracy and smoothness....

Value-Added Growth, Risk Exposure and Economic Sustainability in China’s Agriculture-Related Industries: An Ownership-Based Global Value Chain Analysis

Ensuring the sustainability of agriculture-related industries requires not only expanding value added but also maintaining stable value creation and adaptive capacity under changing economic conditions. This study examines the economic and organizational sustainability of China’s...

Energy-Transfer-Driven[2 + 2] Cycloaddition: Synthesisof Cyclobutane-Fused Tetracycles from Indenes and Maleimides

Abstract Molecular skeletons containing fused cyclobutane rings are of significant value in drug discovery as they can increase the fraction of sp3 carbons (Fsp3) and impart conformational rigidity. Herein, we report a visible-light photocatalytic strategy for the intermolecular...

Reconciling nitrogen fertilization effects on soil nitrification with acidification

Nitrogen (N) fertilization supports nearly half of the global population but disrupts the N cycle. While N addition is assumed to stimulate soil nitrification by increasing substrate supply and nitrifier activity, it may also inhibit nitrification via soil acidification. Resolvin...

Stereoelectronically Controlled Regioselective Allylation of Aldehyde Under Photoredox/Chromium Catalysis

ABSTRACT The formation of structurally defined α,γ‐disubstituted allylmetallic intermediate which could undergo regioselective allylation with carbonyl compounds remains a formidable challenge in synthetic chemistry. Although regioselective in situ formation of α,γ‐disubstituted...
