Abstract In the realm of engineering practice, various factors such as limited availability of measurement data and complex working conditions pose significant challenges to obtaining accurate load spectra. Thus, accurat...

Abstract Gate and earth-rock dam systems are the preferred dam types for river sections under deep overburden conditions, low head, and high flow rates. This study established a three-dimensional finite element model inc...

Abstract In this study, we reported the synthesis and characterization of a novel magnetic polystyrene nanocatalyst functionalized with L-glutamine (L-Glu-MPS) and evaluation of its catalytic performance in a multicompon...

The widespread use of carbon fibre-reinforced polymer (CFRP) composites in sectors such as aerospace and aviation calls for the adoption of sustainable recycling protocols. This research evaluates the mechanical and tomo...

By using the method of model tests and introducing the progressive failure theory into the analysis of disease occurrence and propagation of segment linings of shield tunnels, from the internal force, structural displace...

Abstract Aiming at the problems of easy settlement and insufficient durability of traditional materials under special backfilling conditions in the northwest loess area, this study prepared controllable low-strength read...

Abstract A first-principles study of the structural, electronic, magnetic, mechanical, and optical properties of the double perovskite Ca₂GaAsO₆ is presented using density functional theory with the Perdew-Burke-Ernz...

Abstract The four-track walking mining vehicle can better cope with the complex terrain of cobalt-rich crusts on the seabed. To explore the influence of different parameters on the obstacle-crossing ability of mining veh...

Degradation of images in ocean remote sensing is primarily due to light scattering, chromatic aberration, and stochastic noise. As a result, the quality of the image content has been significantly compromised. Most ocean...

Abstract High-end equipment always operate in low-speed and heavy-load working environments, highlighting the need for cam-lobe hydraulic motors with excellent speed stability (< 1 r/min) and ultrahigh-power rotary outpu...

Abstract Antibiotic residues in aquatic systems accelerate antimicrobial resistance and require efficient solar-driven advanced oxidation strategies. Herein, we engineer an oxygen-vacancy-rich La-doped NiFe₂O₄ spinel...

Abstract Urban metro rail systems are crucial lifelines that play key roles in mobility, accessibility, and economic activity, serving millions daily. However, they are vulnerable to a range of natural and human-induced ...

This study prepared a series of NH2-MIL-125(Ti) samples (denoted as NMT-x%) by tuning the methanol fraction (20%, 30%, 40%, and 50%) in a mixed methanol/N,N-dimethylformamide (MeOH/DMF) solvent system, and investigated t...

Abstract This study investigates the surface morphology, microhardness, and electrochemical corrosion behavior of Ti-Mn alloys reinforced with hydroxyapatite (HA) at 5, 10, and 15 wt% concentrations, fabricated via spark...

Abstract In this work, we use density functional theory (DFT) to thoroughly analyze the structural, electrical, optical, and thermoelectric characteristics of halide double perovskites Rb2AsAuX4 (X = Br, Cl). Both co...

Gold nanoparticles have many applications in the biomedical field, mainly for drug delivery, cancer therapy, and detection of pathogenic microorganisms. In this study, gold nanoparticles synthesized using Platycodon gran...

Skin lesion segmentation poses a challenging problem in medical image analysis, with segmentation performance being highly sensitive to blurred boundaries, noise interference, and morphological diversity. To address thes...

Abstract Herein, Ni²⁺–Al³⁺ co-doped Co0.6−xZn0.4−xNixAlxFe2O4 (0 ≤ x ≤ 0.08) nanoferrites were synthesized via a co-precipitation route to elucidate the role of defect engineering and cation redis...

Based on the concept of true stress and the strain equivalence hypothesis, a three-dimension elastic-plastic damage constitutive model for rock is established. Combining the nonlinear unified strength model as the yield ...

Despite achieving high volumetric overlap, pixel-based deep learning segmentation approaches do not ensure true vascular connectivity, leading to fragmentations structurally analogous to Branch Retinal Artery Occlusions....

Short-term wind speed forecasting remains challenging due to the inherent nonstationarity and multiscale variability of atmospheric processes. This study proposes a hybrid multiscale forecasting framework combining four-...

Background: Students’ prior mathematical knowledge plays a critical role in their success in university mathematics, yet it is often treated diagnostically rather than instructionally. Aim: This study examines studen...

The coal permeability is the key parameter for the gas seepage characteristics and the migration law, and the structural anisotropy of the coal seam makes the permeability have obvious orientation dependence. By assumein...
