Predator-prey systems with defense switching and density-suppressed dispersal strategy
Mathematical Biosciences and Engineering, 2022 In this paper, we consider the following predator-prey system with defense switching mechanism and density-suppressed dispersal strategy $ \begin{equation*} \begin{cases} u_t = \Delta(d_1(w)u)+\frac{\beta_1 uvw}{u+v}-\alpha_1 u, & x\in \Omega, \

Globalization, Stability and the Financial Markets
SSRN Electronic Journal, 2009 The turbulence in East Asia, the contagious effects on financial markets of other emerging economies and even on the major world stock markets, and the renewed instability in exchange rates are, I think, warnings of trouble in a world in which capital is free to flow as never before around the world in amounts and at a speed without precedent.

International Journal of Applied Mathematics and Computer Science, 2022 In this paper, we propose a multi-group SEIR epidemic model with spatial diffusion, where the model parameters are spatially heterogeneous. The positivity and ultimate boundedness of the solution, as well as the existence of a global attractor of the ...

The global stability of M33: still a puzzle [PDF]
, 2019 The inner disc of the local group galaxy M33 appears to be in settled rotational balance, and near IR images reveal a mild, large-scale, two-arm spiral pattern with no strong bar.

Analysis of latent CHIKV dynamics models with general incidence rate and time delays
Journal of Biological Dynamics, 2018 In this paper, we study the stability analysis of latent Chikungunya virus (CHIKV) dynamics models. The incidence rate between the CHIKV and the uninfected monocytes is modelled by a general nonlinear function which satisfies a set of conditions.

Global stability of the positive equilibrium for a non-cooperative model of nuclear reactors
Electronic Journal of Qualitative Theory of Differential Equations, 2012 In this paper, we investigate the non-cooperative reaction-diffusion model of nuclear reactors subject to the homogeneous Neumann boundary condition. By establishing appropriate Lyapunov functions, we prove the global stability of the unique positive ...

Global stability of nonlinear feedback systemswith positive descriptor linear parts [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2019 The global (absolute) stability of nonlinear systems with negative feedbacks and positive descriptor linear parts is addressed. Transfer matrices of positive descriptor linear systems are analyzed.

Almost sure exponential stability of backward Euler–Maruyama discretizations for hybrid stochastic differential equations [PDF]
, 2011 This is a continuation of the first author's earlier paper [1] jointly with Pang and Deng, in which the authors established some sufficient conditions under which the Euler-Maruyama (EM) method can reproduce the almost sure exponential stability of the ...

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...
