Spreading Dynamics of SHIPR Pyramid Scheme Model on Scale-Free Networks

open access: yesIEEE Access, 2021
Nowadays, pyramid schemes have caused extremely negative effects on people’s lives and seriously damaged the social economy. With the rapid development of network and communication technology, people’s direct or indirect social interaction ...

Influence of the mode of reproduction on dispersal evolution during species invasion [PDF]

open access: yesESAIM: Proceedings and Surveys, 2020
We consider a reaction-diffusion-reproduction equation, modeling a population which is spatially heterogeneous. The dispersion of each individuals is influenced by its phenotype.

Minimal wave speed of traveling wavefronts in delayed Belousov-Zhabotinskii model

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
This paper is concerned with the traveling wavefronts of Belousov-Zhabotinskii model with time delay. By constructing proper upper and lower solutions and applying the theory of asymptotic spreading, the minimal wave speed is obtained under the weaker ...

Identify hidden spreaders of pandemic over contact tracing networks

open access: yesScientific Reports, 2023
The COVID-19 infection cases have surged globally, causing devastations to both the society and economy. A key factor contributing to the sustained spreading is the presence of a large number of asymptomatic or hidden spreaders, who mix among the ...

Numerical simulation of spreading drops [PDF]

open access: yes, 2013
We consider a liquid drop that spreads on a wettable surface. Different time evolutions have been observed for the base radius r depending of the relative role played by inertia, viscosity, surface tension and the wetting condition. Numerical simulations

On a Multistable Type of Free Boundary Problem with a Flux at the Boundary

open access: yesAdvances in Mathematical Physics, 2023
This paper studies the free boundary problem of a multistable equation with a Robin boundary condition, which may be used to describe the spreading of the invasive species with the solution representing the density of species and the free boundary ...

On a reaction–diffusion–advection system: fixed boundary or free boundary

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2018
This paper is devoted to the asymptotic behaviors of the solution to a reaction–diffusion–advection system in a homogeneous environment with fixed boundary or free boundary.
