Asymptotic stability, an in-depth treatment

open access: yes, 2012
This chapter defines local pre-asymptotic stability for a compact (closed and bounded) set and studies its properties for systems that are nominally well-posed or well-posed.

Nonlinear Dynamics and Invariants of Motion in ReRAM Cells

open access: yesAdvanced Electronic Materials, EarlyView.
A second‐order cell, hosting one capacitor and two back‐to‐back ReRAMs, admits Invariants of Motion: its states lie on one‐dimensional manifolds at all times. The cell shows quiescent monostability or bistability, depending on the manifold index. At equilibrium, the capacitor voltage vanishes.

Stability analysis of a fractional-order two-species facultative mutualism model with harvesting

open access: yesAdvances in Difference Equations, 2017
We present a fractional-order model of two-species facultative mutualism with harvesting. We investigate the stability of the equilibrium points of the model by using the linearization method for noncoexistence of equilibrium points and the Lyapunov ...

Reference Electrode‐Free Nitrate Sensing via Differential Temperature‐Modulated Potentiometry in Printed Symmetric SC‐ISEs

open access: yesAdvanced Electronic Materials, EarlyView.
This work proposes and validates a method for measuring nitrate concentration with printed, solid‐state ion‐selective electrodes that does not require a stable reference electrode. The approach uses brief, localized heating pulses to generate a concentration‐dependent voltage response that is drift‐resilient and log‐linear from 0.1 to 100 mm, while ...

Exponential asymptotic stability for linear volterra equations [PDF]

open access: yes, 2000
This note studies the exponential asymptotic stability of the zero solution of the linear Volterra equation x˙ (t) = Ax(t) + t 0 K(t − s)x(s) ds by extending results in the paper of Murakami “Exponential Asymptotic Stability for scalar linear ...

Almost Surely Asymptotic Stability of Exact and Numerical Solutions for Neutral Stochastic Pantograph Equations

open access: yesAbstract and Applied Analysis, 2011
We study the almost surely asymptotic stability of exact solutions to neutral stochastic pantograph equations (NSPEs), and sufficient conditions are obtained.

Counter‐Halide‐Directed Ion‐Pair Passivation Enables High‐Performance Wide‐Bandgap Perovskites for Perovskite/Cu(In,Ga)Se2 Tandem Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Counter‐halide engineering of fluorobenzylammonium surface passivators reveals bromide as the optimal partner for wide‐bandgap perovskites. FBz–Br effectively stabilizes halide‐vacancy‐related defects and undercoordinated Pb sites, suppresses non‐radiative recombination, and enhances surface hydrophobicity and thermal stability.

LaSalle stationary oscillation theorem for affine periodic dynamic systems on time scales

open access: yesBoundary Value Problems, 2019
In this paper, for affine periodic systems on time scales, we establish LaSalle stationary oscillation theorem to obtain the existence and asymptotic stability of affine periodic solutions on time scales.
