Mathematical Model of a Thermoelastic Micro-elongated Plate Influenced by Initial Stress and an Upper Load from a Piezoelectric Layer according to Dual-phase-lag Model [PDF]
Journal of Applied and Computational MechanicsThe main goal of this work is to investigate how the initial stress affects a thermoelastic micro-elongated layer under a layer of piezoelectric loading using the theory of Lord-Shulman (L-S) with relaxation time and the model of dual-phase-lag (DPL ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives
Biological Reviews, EarlyView.ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.
