International Journal for Numerical Methods in Engineering, Volume 126, Issue 2, 30 January 2025.ABSTRACT Implicit‐explicit (IMEX) time integration schemes are well suited for non‐linear structural dynamics because of their low computational cost and high accuracy. However, the stability of IMEX schemes cannot be guaranteed for general non‐linear problems.

A Fully Coupled Numerical Solution of Water, Vapor, Heat, and Water Stable Isotope Transport in Soil
Water Resources Research, Volume 61, Issue 1, January 2025.Abstract Modeling water stable isotope transport in soil is crucial to sharpen our understanding of water cycles in terrestrial ecosystems. Although several models for soil water isotope transport have been developed, many rely on a semi‐coupled numerical approach, solving isotope transport only after obtaining solutions from water and heat transport ...

Electronics Letters, Volume 61, Issue 1, January/December 2025.(1) ESPM (equivalent small parameter method)‐based steady‐state modelling of fractional‐order PWM converters with non‐consistent‐period dynamics is proposed and demonstrated on a two‐phase interleaved fractional‐order boost DC–DC converter considering parasitic effects. (2) Rigorous analysis reveals the slow‐scale instability mechanism and the combined
