Attractor and Boundedness of Switched Stochastic Cohen-Grossberg Neural Networks
Discrete Dynamics in Nature and Society, 2016 We address the problem of stochastic attractor and boundedness of a class of switched Cohen-Grossberg neural networks (CGNN) with discrete and infinitely distributed delays.

Strong Exponential Attractors for Weakly Damped Semilinear Wave Equations
Journal of Mathematics, 2020 In this paper, we investigate the longtime dynamics for the damped wave equation in a bounded smooth domain of ℝ3. The exponential attractor is investigated in a strong energy space for the case of subquintic nonlinearity, which is based on the recent ...

Estimates on the dimension of an exponential attractor for a delay differential equation
, 2014 We study the long time behavior of delay differential equation, considered in a bounded domain in ℝd. Using the short trajectory method to prove the existence of the exponential attractor. Also we have estimates on the fractal dimension of an exponential

Global Stability of Approximation for Exponential Attractors
Funkcialaj Ekvacioj, 2004 This paper is concerned with the initial value problem for some diffusion system which describes the process of a pattern formation of biological individuals by chemotaixis and growth. In the paper Osaki et al. [13], exponential attractors have been constructed for the dynamical system determined by this problem.

Improved Strength and Corrosion Resistance of Ti–50Zr Alloy Through Heat Treatment
Advanced Engineering Materials, EarlyView.This work systematically analyzes the effects of heat treatment on mechanical properties and corrosion behavior of Ti‐50Zr alloy produced via vacuum arc melting. Microstructure transforms from coarse lamellar α phase in as‐cast condition to fine and uniformly distributes acicular α′ phase in heat‐treatment state.

A New Chaotic Attractor with Quadratic Exponential Nonlinear Term from Chen’s Attractor
International Journal of Analysis and Applications, 2014 In this paper a new three-dimensional chaotic system is proposed, which relies on a nonlinear exponential term and a nonlinear quadratic cross term necessary for folding trajectories.

Dynamical system approach of non-minimal coupling in holographic cosmology
Nuclear Physics B, 2019 We study the dynamical system approach of non-minimally coupled scalar field to induced gravity on the brane in the framework of holographic cosmology. In this context, we derive the modified Friedmann equation and the equation of motion. The dynamics of
