True triaxial tests on unsaturated soils with suction-controlled condition
Based on the new true triaxial apparatus of Xi’an University of Technology, the pedestal of the pressure chamber is installed with a high-air-entry-value ceramic disk and porous plate is placed on the top of the specimens.

Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

1. The synergistic effects of carbonate mineral dissolution, coal matrix drying/shrinkage, and supercritical CO2 (ScCO2)‐induced organic matter extraction collectively enhance pore/fracture connectivity, thereby significantly improving permeability. 2.

Similar locomotor patterns across Quarter Horse disciplines inform lameness assessment
Abstract Background Lineage‐based selection is central to the Quarter Horse industry and is often justified by the assumption that morphology determines locomotor function. However, objective evidence linking static conformation to discipline‐specific locomotor behaviour under standardised conditions remains limited.

Abstract Background In clinical practice, lameness evaluation often relies on visual assessment under different examination conditions, including ground and figures, and remains subjective. Although objective symmetry indices provide quantitative measures of gait asymmetry, their interpretation across multiple conditions remains challenging because ...

Abstract Background Attention‐deficit/hyperactivity disorder (ADHD) symptoms are associated with adverse health outcomes; this may be partially due to unhealthy lifestyle factors such as low physical activity (PA) and high sedentary behavior (SED). However, this association remains unclear.

An Open Database of Lunar Regolith and Simulants Properties
ABSTRACT Lunar regolith, the layer of unconsolidated material covering the Moon's surface, is central to the science and technology developed for the Moon, notably related to in‐situ science investigations, resource utilization, surface infrastructure, and mobility systems.

Hypoplasticity for Sand With Explicitly Defined Asymptotic States
ABSTRACT A hypoplastic model for sand with defined asymptotic states is proposed. The fourth‐order tensor A$\mathsf {A}$ is defined by modifying the compression relation of the reference hypoplastic model by von Wolffersdorff (HP). This enables the mathematical formulation of a hypoplastic model for sand including the asymptotic state boundary surface (

A double intercritical annealing strategy is proposed to tailor the multiphase microstructure and mechanical response of a medium‐Mn steel. The treatment produces an ultrafine mixture of ferrite, martensite and multiple austenite populations with graded thermal and mechanical stability, formed through austenite reversion and controlled retransformation.
