Soil-structure interaction effects on the static disproportionate failure resistance of reinforced concrete frames: A staged numerical study using finite-element and finite-difference methods

The present numerical investigation evaluates how Soil Structure Interaction (SSI) affects the static Disproportionate Failure (DF) behavior of Reinforced Concrete (RC) frames subjected to localized column removal. The numerical framework uses Finite Element (FE) modeling in Seis...

Organic acid-regulated self-assembly and anti-oxidation of low-defect Sn-Pb perovskite nanocrystals toward optical anti-counterfeiting applications

Tin-lead mixed perovskite nanocrystals (NCs) attract extensive research interest for narrow bandgap and low toxicity, yet inherent surface defects, weak crystallinity and easy Sn 2+ oxidation severely degrade their stability and usability. This work adopts four organic acids (FA,...

Thermal conductivity characteristics and predictive modeling of rubber sand composite geomaterials under multiple influencing factors

Waste tire rubber has low density, high elasticity, and excellent fatigue resistance. When mixed with sand, it forms a sustainable composite geomaterial in which thermal conductivity (TC) governs thermal performance. This study systematically investigated the TC of rubber-sand co...

Prediction and optimization of tire-pavement noise for ultra-thin friction course based on surface texture

Tire–road noise is a major component of traffic noise and becomes increasingly dominant under medium- and high-speed driving conditions. Pavement surface texture plays a critical role in tire–road noise generation; however, existing prediction approaches remain limited in capturi...

Trajectories of cardiopulmonary adaptation and executive function in elite endurance athletes receiving transcranial direct current stimulation with interval training

This study examined how transcranial direct current stimulation (tDCS) interacts with high-intensity interval training (HIIT) to shape cardiopulmonary fitness and executive function in elite endurance athletes across an 8-week protocol. Sixty-six nationally ranked athletes were s...

PP cotton-wrapped subsurface drip irrigation can increase potato yield and sustainability in arid regions

Although subsurface drip irrigation (SDI) is widely used for shallow-rooted crops in arid regions, it still suffers from exogenous clogging, and effective, systematic physical protection measures are lacking. Therefore, a 3 × 4 two-factor factorial field experiment was conducted...

UAV-based super-resolution instance segmentation enables ecological monitoring of sea cucumbers in shallow coral reef habitats

Accurate monitoring of sea cucumbers from UAV imagery remains challenging because submerged individuals often exhibit low contrast, camouflage against coral-rubble backgrounds, and weak boundary information under water-surface disturbance. In particular, key visual cues such as b...

Pore-scale transport and adsorption behavior of Mn(II) in CT-reconstructed adsorptive permeable filling materials for mine water pollution control

Constructing underground reservoirs in coal mine goafs can effectively mitigate surface subsidence and facilitate large-scale utilization and purification of mine water. However, seepage characteristics within backfill bodies and the migration–adsorption behavior of Mn 2+ remain...

Correlation Between Gut Microbiota Shifts, Lipopolysaccharide Levels, and Neuroinflammatory Responses Following Ischemic Stroke

Background: The microbiota–gut–brain axis (MGBA) is increasingly recognized as a contributor to ischemic stroke pathophysiology, yet the relationship between gut microbial changes and neuroinflammation remains incompletely understood. This study aimed to investigate whether shift...

Enhancing flotation selectivity via ultrasonic treatment on the froth: foam characteristics and underlying mechanisms

In flotation, improving selectivity is crucial to reduce concentrate ash content and achieve clean coal utilization; however, nonselective entrainment of fine gangue frequently degrades separation performance. This work innovatively applies ultrasound to the froth to investigate...

Experimental Investigation on the Evolution Mechanism of Resistivity in Limestone Under Triaxial Loading-Induced Damage

Electrical resistivity is a sensitive indicator of rock damage, yet the quantitative link between pore-structure change and resistivity response under varied hydro-thermo-mechanical conditions remains poorly constrained. In this study, triaxial compression tests were conducted on...

Effects of Supplemental Drip Fertigation on Grain Yield and Water and Nitrogen Use Efficiencies of Spring Maize in the Dryland Farming Region of the Eastern Loess Plateau

Water–nitrogen mismatch constrains stable and resource-efficient spring maize production in the eastern Loess Plateau. A two-year field experiment was conducted in Jinzhong, Shanxi Province, China, during 2024–2025. Supplemental irrigation was applied three, four, or five times i...

Multi-feature SCPTU data driven prediction of undrained shear strength of clay using DBO-optimized CNN-BiLSTM with attention mechanism

Accurate estimation of the undrained shear strength (Su) of clay remains challenging due to the complex and nonlinear interactions inherent in multi-source in-situ test data. To address this issue, we propose DBO-CNN-BiLSTM-Attention (DBO-CBA), a novel hybrid deep learning framew...

Posterior insula activity is associated with VR sickness severity after prolonged immersion: a resting-state fMRI study

The neural mechanisms underlying virtual reality (VR) sickness remain poorly understood. This study explored neural alterations following prolonged VR immersion and their associations with VR sickness severity using resting-state functional magnetic resonance imaging (fMRI). Frac...

Surrogate-Assisted Inverse Design of the Power-Law Index in Axially Functionally Graded Fluid-Conveying Pipes for Target Modal and Deflection Performance

A surrogate-assisted inverse design framework is presented for selecting the power-law index of clamped–clamped axially functionally graded (AFG) Timoshenko pipes conveying fluid. The GITT model, 336-sample database, and trained MLP forward surrogate were developed in our previou...

A quantitative framework for evaluating overburden disturbance and surface subsidence induced by coal seam mining

Abstract Coal seam mining inevitably causes varying degrees of disturbance to the overlying strata and surface environment, necessitating the establishment of a scientific and systematic quantitative assessment framework for overburden disturbance. This study introduces a compreh...

Study on the macro-micro mechanisms of mineralized sand columns based on dual-enzymatically induced carbonate precipitation

Enzyme-induced carbonate precipitation (EICP) shows great promise in consolidating loose materials. However, traditional single-enzyme systems have limitations such as low precipitation efficiency, uneven spatial distribution and difficulty controlling reaction rates. This makes...

Picking Point Localization and Path Planning for Hotan Rose Based on a Lightweight Segmentation Model

The Hotan rose, a high-value specialty crop cultivated in Xinjiang, exhibits pronouncedly non-uniform flowering phenology, which has historically necessitated labor-intensive manual harvesting. To date, however, no integrated framework has been reported that concurrently addresse...
