Bifurcation Behavior Analysis in a Predator-Prey Model
Discrete Dynamics in Nature and Society, 2016 A predator-prey model is studied mathematically and numerically. The aim is to explore how some key factors influence dynamic evolutionary mechanism of steady conversion and bifurcation behavior in predator-prey model.

A bacteriophage model based on CRISPR/Cas immune system in a chemostat
Mathematical Biosciences and Engineering, 2017 Clustered regularly interspaced short palindromic repeats (CRISPRs) along with Cas proteins are a widespread immune system across bacteria and archaea.

Complexity, Volume 2025, Issue 1, 2025.We investigate the nonlinear dynamics of a discrete‐time predator–prey model governed by a Holling Type‐II functional response. Starting from a biologically motivated continuous‐time system, we derive its discrete analogue via the explicit Euler method and employ nondimensionalization to reduce the number of parameters.

Endogenous income taxes and indeterminacy in dynamic models: When Diamond meets Ramsey again. [PDF]
This paper introduces fiscal increasing returns, through endogenous labor income tax rates as in Schmitt-Grohe and Uribe (1997), into the overlapping generations model with endogenous labor, consumption in both periods of life and homothetic preferences (

Reducing or enhancing chaos using periodic orbits
, 2006 A method to reduce or enhance chaos in Hamiltonian flows with two degrees of freedom is discussed. This method is based on finding a suitable perturbation of the system such that the stability of a set of periodic orbits changes (local bifurcations ...

Bifurcation in a Fractional SIR Model With Normalized Caputo–Fabrizio Derivative
Discrete Dynamics in Nature and Society, Volume 2025, Issue 1, 2025.Models of fractional‐order epidemics more accurately represent memory and hereditary effects compared to traditional integer‐order models. However, many Caputo–Fabrizio (CF) SIR models utilize a non‐normalized kernel, which can distort the scaling and understanding of memory.

Spiral attractors as the root of a new type of "bursting activity" in the Rosenzweig-MacArthur model
, 2018 We study the peculiarities of spiral attractors in the Rosenzweig-MacArthur model, that describes dynamics in a food chain "prey-predator-superpredator".

Local/global analysis of the stationary solutions of some neural field equations
, 2009 Neural or cortical fields are continuous assemblies of mesoscopic models, also called neural masses, of neural populations that are fundamental in the modeling of macroscopic parts of the brain.

Symmetry-breaking transitions in networks of nonlinear circuit elements
, 2010 We investigate a nonlinear circuit consisting of N tunnel diodes in series, which shows close similarities to a semiconductor superlattice or to a neural network. Each tunnel diode is modeled by a three-variable FitzHugh-Nagumo-like system.
