Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten

physica status solidi (b), EarlyView.
This atomic‐scale study reveals how low‐to‐mid‐energy space irradiation alters tungsten's thermal and electronic behavior, even at low defect levels. Focusing on vacancy sites in bulk and near grain boundaries, it employs two novel approaches: site‐projected thermal conductivity and the N2$^{2}$ method for the thermal and electronic response analysis ...

Distributed Leader‐Following Formation of Discrete‐Time Multi‐Agent LPV Systems

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper addresses the leader‐following formation consensus problem for multi‐agent systems (MASs) with agents represented by discrete‐time linear parameter‐varying (LPV) models. The scenario where each agent can be modeled with distinct time‐varying scheduling parameters is investigated with respect to compensation signals.
