Network inoculation: Heteroclinics and phase transitions in an epidemic model. [PDF]

Chaos, 2016
In epidemiological modelling, dynamics on networks, and in particular adaptive and heterogeneous networks have recently received much interest. Here we present a detailed analysis of a previously proposed model that combines heterogeneity in the ...

Design of Grid Multi-Wing Chaotic Attractors Based on Fractional-Order Differential Systems

Frontiers in Physics, 2022
In this article, a new method for generating grid multi-wing chaotic attractors from fractional-order linear differential systems is proposed. In order to generate grid multi-wing attractors, we extend the method of constructing heteroclinic loops from ...

Dynamics in a Predator–Prey Model with Cooperative Hunting and Allee Effect

Mathematics, 2021
This paper deals with a diffusive predator–prey model with two delays. First, we consider the local bifurcation and global dynamical behavior of the kinetic system, which is a predator–prey model with cooperative hunting and Allee effect.

Fear Effect on a Predator–Prey Model with Non-Differential Fractional Functional Response

Fractal and Fractional, 2023
In this paper, we study the factor of the fear effect in a predator–prey model with prey refuge and a non-differentiable fractional functional response due to the group defense.

A Three Dimensional Lagrangian Analysis of the Smoke Plume From the 2019/2020 Australian Wildfire Event

Journal of Geophysical Research: Atmospheres, Volume 128, Issue 21, 16 November 2023., 2023
Abstract During the 2019/2020 Australian bushfire season, intense wildfires generated a rising plume with a record concentration of smoke in the lower stratosphere. Motivated by this event, we use the atmospheric wind reanalysis model ERA5 to characterize the three dimensional atmospheric transport in the general region of the plume following a ...

Building modern coexistence theory from the ground up: The role of community assembly

Ecology Letters, Volume 26, Issue 11, Page 1840-1861, November 2023., 2023
Modern coexistence theory (MCT) is limited by its dependence on the naive invasion growth rate criterion. We extend the applicability of MCT by using permanence theory. We use this newly developed method to gain new insights into community coexistence and its limits.

Nonlinear stochastic dynamics research on a Lorenz system with white Gaussian noise based on a quasi‐potential approach

International Journal of Mechanical System Dynamics, Volume 3, Issue 1, Page 85-94, March 2023., 2023
Abstract Environmental noise can lead to complex stochastic dynamical behaviors in nonlinear systems. In this paper, a Lorenz system with the parameter region with two stable fixed points and a chaotic saddle subject to white Gaussian noise is investigated as an example.
