Journal ArticleDOI
A general multi-strain model with environmental transmission: invasion conditions for the disease-free and endemic states.
TL;DR: An SIR-type multi-strain disease transmission model with perfect cross immunity where environmental transmission is broadly defined by three axioms is introduced, suggesting that environmental transmission makes the endemic state less resistant to invasion.
Journal ArticleDOI
Nonlinear dynamic analysis of an epidemiological model for COVID-19 including public behavior and government action.
TL;DR: In this article, a nonlinear susceptible, exposed, infectious and removed transmission model with added behavioral and government policy dynamics is used to model the COVID-19 pandemic. But the model is not suitable for the analysis of the entire world.
Journal ArticleDOI
Population Floors and the Persistence of Chaos in Ecological Models.
Graeme D. Ruxton,Pejman Rohani +1 more
TL;DR: The effects of perturbing several of these models so as to introduce a non-zero minimum population size are described, which generally reduces the likelihood of observing chaos, in both discrete and continuous time models.
Journal ArticleDOI
The statistics of epidemic transitions.

TL;DR: Because the system dynamics exhibit characteristic fluctuations in response to perturbations for a system in the vicinity of a critical point, it is proposed this information may be harnessed to develop early warning signals.
Journal ArticleDOI
Immigration and the persistence of chaos in population models
Pejman Rohani,Octavio Miramontes +1 more
TL;DR: In this paper, a simple population model was presented that exhibits both the period-doubling and the quasi-periodic routes to chaos with the variation of a single parameter, and the relative robustness of the two routes against structural perturbations in the form of added immigration terms was compared.
