Existence of solutions for an n-dimensional operator equation and applications to BVPs
Electronic Journal of Differential Equations, 2014 By applying the Guo-Lakshmikantham fixed point theorem on high dimensional cones, sufficient conditions are given to guarantee the existence of positive solutions of a system of equations of the form $$ x_i(t)=\sum_{k=1}^n\sum_{j=1}^n\gamma_{ij}(t ...

Nucleation and Propagation of Traveling Charge Domains in a Planar AlGaN/GaN Triode Structure
physica status solidi (a), EarlyView.This work presents a novel model for the nucleation of charge domain instabilities in semiconductors exhibiting negative differential drift velocity, identifying diffusion as the key factor inhibiting domain formation. A planar Gunn triode structure is proposed which overcomes obstacles to the realization of GaN‐based Gunn effect devices with ...

Structure and Migration Mechanisms of Oxygen Interstitial Defects in β‐Ga2O3
physica status solidi (b), EarlyView.The structures and diffusion mechanisms of interstitial oxygen in different charge states in β‐Ga2O3 are extensively studied using density functional theory. The results provide a detailed map of the potential energy surface for oxygen interstitials in β‐Ga2O3 and demonstrate how these ions migrate between different rings in the structure.

International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT This work addresses the problem of developing a nonfragile sliding mode observer for fractional‐order complex networked systems (FO‐CNS) under stochastic network attacks. The proposed approach employs a combination of event‐triggered techniques. First, a nonfragile fractional‐order state observer is developed, enabling the design of a suitable
