A Multiphysics Engineering Model of pH and Oxygen Transport Limitations in Textile‐Based Wearable Lactate Biosensors

Engineering Reports, Volume 8, Issue 6, June 2026.
A one‐dimensional multiphysics engineering model is developed to elucidate the coupled transport and reaction phenomena governing textile‐based wearable lactate biosensors operating in sweat. The model integrates diffusion of lactate, oxygen, hydrogen peroxide, and protons with dual‐substrate enzymatic kinetics, acid–base equilibria, and mediator‐based

From Stability to Chaos: A Complete Classification of the Damped Klein‐Gordon Dynamics

Mathematical Methods in the Applied Sciences, Volume 49, Issue 9, Page 9696-9708, June 2026.
ABSTRACT We investigate the transition between stability and chaos in the damped Klein‐Gordon equation, a fundamental model for wave propagation and energy dissipation. Using semigroup methods and spectral criteria, we derive explicit thresholds that determine when the system exhibits asymptotic stability and when it displays strong chaotic dynamics ...

On Cahn–Hilliard Type Viscoelastoplastic Two‐Phase Flows

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT This contribution deals with a model for viscoelastoplastic two‐phase flows of Cahn–Hilliard type. We present the modeling framework for the flow, the notion of a generalized solution, namely the so‐called dissipative solution, and the key ideas of the existence proof.
