A Stabilized Mixed Hybrid Finite Element Framework for Large-Deformation Poromechanics with Torsion: Application to Transmural Perfusion and Vascular Hemodynamics

This paper presents a stabilized mixed hybrid finite element framework that effectively resolves volumetric locking and pressure oscillations in large-deformation poromechanics under torsion, demonstrating through analytical and numerical validation that torsional twist significantly reduces endocardial fiber stress and improves perfusion modeling accuracy in hypertensive hearts compared to standard formulations.

From spatial attribution to mesh decisions in nonlinear moisture-threshold calculations

This study establishes a cost-accounted, interpretable procedure for linking local flux sensitivity to optimal mesh selection in nonlinear moisture-threshold calculations by validating coupled tangent and adjoint methods, comparing spatial grading strategies against goal-oriented approaches, and quantifying the impact of constitutive laws and latent cooling on numerical drying endpoints.

Sulphate and chloride durability of metakaolin-blended palm kernel shell concrete masonry units: separating the contributions of the pozzolan and the agro-waste aggregate

This study demonstrates that while metakaolin significantly enhances the sulphate and chloride durability of palm kernel shell concrete masonry units by refining pore structure, the inclusion of the lightweight agro-waste aggregate partially offsets these gains, resulting in a net durability improvement that correlates weakly with water-accessible porosity and is characterized by matrix softening rather than mass loss.

Influence of Annealing Treatment on Electrical Steel Characteristics and Electric Machine Performance

This study demonstrates that applying multi-stage controlled or high-temperature rapid annealing treatments to electrical steel significantly enhances the magnetic properties and reduces core losses of a BLDC motor compared to the untreated as-cut condition, thereby improving overall machine performance.

Overhead Transmission Line Fragility, Climate-Induced Risks and Geospatial Artificial Intelligence: A Systematic Bibliometric Review

This systematic bibliometric review reveals that while research on overhead transmission line fragility has increasingly incorporated artificial intelligence and machine learning, it remains fragmented with weak integration of climate and geospatial perspectives, significant regional biases, and a lack of comprehensive frameworks to address cumulative multi-hazard climate impacts.

A data-driven framework to inform extreme flood warning: Evaluating dual-tier weighting in contrasting catchments

This study demonstrates that a data-driven framework employing dual-tier residual weighting significantly improves extreme flood detection in low-yield, attenuated catchments without compromising continuous streamflow simulation, provided that the weighting strategy is tailored to the catchment's specific hydrological characteristics and paired with an appropriate objective function.
