Research on the impact mechanical response characteristics of gas containing coal and rock based on RSM

To investigate the dynamic mechanical behavior of gas-containing coal in deep coal mines, dynamic compression tests were conducted on gas-containing coal using a 50 mm diameter split Hopkinson pressure bar (SHPB) system. The central composite design (CCD) method within response s...

Integrating deep learning and pangenomics to recover missing heritability from wild structural variations

Crop domestication has induced a severe genetic bottleneck that reduces the adaptive diversity present in modern cultivars. Standard intra-population genomic prediction models reliant on linear reference genomes and SNPs fail to capture the full spectrum of phenotypic variance hi...

Integrated analysis of surface water-groundwater interactions and enhanced hydrological forecasting of glacierized river in cold and arid regions

Abstract In cold and arid regions, climate change has altered precipitation patterns and accelerated glacierized retreat, which imposes severe risks on the stability of regional hydrological systems. Combined with the strong interactions between surface water (SW) and groundwater...

Natural variation in LuGnTL modulates the trade-off between plant height and seed size in flax (Linum usitatissimum L.)

Flax is an ancient crop cultivated for both fiber and oil, and it has undergone divergent selection into two distinct morphotypes: semi-dwarf oil flax with large seeds and tall fiber flax with small seeds. However, the genetic architecture underlying the trade-off between plant h...

Mechanical properties and fracture failure characteristics of fractured limestone under coupled freeze-thaw and cyclic loading

<title>Abstract</title> The Central Asian Orogenic Belt possesses abundant mineral resources. As mining activities extend into high-altitude cold regions, the safety and stability of rock engineering projects, such as open-pit mine slopes, have become increasingly prominent. This...

Compression Deformation Characteristics of Frozen Soil Containing Ice Lenses Under an Asymmetric Temperature Field

Frozen soil on alpine slopes is influenced by inclination and aspect-induced differential solar radiation effects, resulting in non-uniform temperature fields and inclined layered ice lenses that enhance anisotropy and degrade mechanical properties. This study investigates the de...

Manipulating Valence‐Heterogeneous Pt Dual Sites via Metal‐Support Interactions for Highly Efficient Alkaline Hydrogen Evolution

ABSTRACT Alkaline water electrolysis is essential for sustainable green hydrogen production but is bottlenecked by sluggish water dissociation kinetics and catalyst degradation at high current densities. Herein, a low loading of Pt nanoclusters (4.2 wt.%) was anchored on multiwal...

A CNN Feature Extraction and BKA-Optimized LSSVM Classification Method for Small-Sample Rolling Bearing Fault Diagnosis

Rolling bearings are indispensable elements in mechanical equipment, and their condition is closely related to system reliability and operational safety. To enhance diagnostic performance with limited samples and reduce the dependence on manual parameter selection, this study pro...

Reversible Local CoordinationRelaxation of Lattice-EmbeddedRh Single Sites Enables Efficient and Durable Propene Hydroformylation

Abstract Efficient atomically dispersed Rh catalysts for propene hydroformylation require active sites that combine coordination flexibility during turnover with resistance to leaching and aggregation. Here we report Rh1@ZnO, in which Rh single sites are incorporated into cation...

Performance and Economic Boundary Analysis of an Integrated PV–Solar-Thermal–Battery–Hydrogen System for a Cold-Climate Dwelling: A Case Study in Northern Japan

Cold-climate dwellings can face coincident electricity and domestic hot-water shortfalls in winter, when solar availability is at its lowest. This study evaluates an integrated residential system for Aomori, Japan, combining photovoltaics, evacuated-tube solar water heating, and...

Chalcogen Bond‐Induced Conformational Locking for Thermoplastic Polyurethane With Superior Puncture Force and Fracture Energy

ABSTRACT A fundamental and long‐standing issue in the design of polymers is how to transcend the constraints of conformational entropy within highly disordered polymer networks, thereby enabling the deterministic orientation of local chemical bonds. While such precision is common...

Pseudo defect guided meta calibration for few shot industrial defect segmentation

Few-shot industrial defect segmentation aims to localize unseen defects from only a few defect-free reference images, but remains challenging because no positive anomaly examples are available and defects are often subtle, irregular, and embedded in complex textures. We propose P...

Link-adaptive edge-cloud inference for UAV-based plastic mulch residue assessment

Plastic mulch residue assessment from UAV imagery is jointly constrained by segmentation accuracy, end-to-end latency and uplink bandwidth, since onboard inference loses boundary fidelity on fragmented film while cloud inference is throttled by the link, and these constraints hav...

Moisture Migration and Variation in Pile Shaft Resistance During Hydration-Heat-Induced Thawing–Refreezing Around Cast-in-Place Piles in Permafrost

The shaft resistance of cast-in-place piles in permafrost regions is commonly estimated using the initial moisture content and frozen-soil strength parameters obtained during site investigation. However, concrete hydration heat disturbs the temperature field of the surrounding fr...

Urban Resilience Capacity Assessment and Key Factor Contribution Analysis in the Northern Slope of Tianshan Mountains Urban Agglomeration: Based on the XGBoost Model

Addressing the issue of ecological vulnerability and against the backdrop of urban expansion in arid regions, this study constructs a composite urban resilience capacity index (CURCI) for the urban agglomeration on the northern slopes of the Tianshan Mountains and examines its sp...

Coupling Effects of Texture Density and Counterpart Material Hardness on the Dry Sliding Friction of TC4 Titanium Alloy

Circular microtextures with area densities of 5%, 10%, 15%, and 20% were fabricated on TC4 titanium alloy surfaces and tested under dry sliding conditions against four counterpart balls of varying hardness (Brass, SUS304, AISI 52100, and K20). Through coefficient of friction (COF...
