Parametric Sensitivity Assessment of Slip Flow and Thermophoretic Effects on a Vertical Stretching Surface Using Response Surface Methodology

This study utilizes MATLAB's bvp4c solver, Response Surface Methodology, and Artificial Neural Networks to demonstrate that increasing the velocity slip parameter significantly enhances heat transfer and reduces skin friction in magnetohydrodynamic boundary-layer flow over a vertical stretching surface, outperforming the effects of energy slip and thermophoresis.

A Next-Generation Nonstationary Stochastic Ground Motion Modelling of the 2001 Bhuj Earthquake: A Multi-Peak Gamma–Driven Filtered White-Noise Approach with Uncertainty Quantification and GMPE Benchmarking

This study presents a fully nonstationary stochastic ground motion model for the 2001 Bhuj intraplate earthquake that integrates a multi-peak gamma-driven modulating function, time-varying damping, and Johnson SU non-Gaussian transformations to accurately replicate observed seismic characteristics, quantify parameter uncertainty, and validate against regional ground motion prediction equations for robust seismic risk assessment.

Highly Transient Thermal Runaway and Gas Emission Dynamics of LiFePO 4 Batteries under Extreme Overcharge Conditions

This study systematically investigates the highly transient thermal runaway, pyrolysis, and gas emission dynamics of commercial 15 Ah LiFePO4 batteries under extreme high-rate overcharging (up to 12C), revealing that increased charging rates significantly accelerate triggering times and destructive thermo-electrical-mechanical behaviors, thereby providing critical insights for next-generation energy system safety.

Readout-Gramian Kinematics of Optical Phase Singularities: Jacobian Collapse, Fold Annihilation, and Apparent Superluminal Defect Motion

This paper introduces a readout-Gramian framework to demonstrate that the apparent superluminal motion of optical phase singularities is a geometric artifact of chart failure caused by the collapse of the Fisher-information metric (Jacobian) near fold annihilation events, rather than a violation of physical signal velocity limits.

Energy-Scale Matching Multicriticality in Relativistic Degenerate Matter

This paper identifies a unique dielectric multicritical point in relativistic degenerate quantum plasmas where the matching of Coulomb and relativistic degeneracy energy scales causes the collapse of screening poles and a transition from quadratic to quartic spatial dispersion, fundamentally altering the screening mechanism at densities near the onset of relativistic degeneracy.
