On an age-structured juvenile-adult model with harvesting pulse in moving and heterogeneous environment
Haiyan Xu, Zhigui Lin, Huaiping Zhu
This paper concerns an age-structured juvenile-adult model with harvesting pulse and moving boundaries in a heterogeneous environment, in which the moving boundaries describe the n…
Detection of bistable structures via the Conley index and applications to biological systems
Junbo Jia, Pan Yang, Huaiping Zhu +3
Bistability is a ubiquitous phenomenon in life sciences. In this paper, two kinds of bistable structures in dynamical systems are studied: One is two one-point attractors, another…
Four-tier response system and spatial propagation of COVID-19 in China by a network model
Jing Ge, Daihai He, Zhigui Lin +2
In order to investigate the effectiveness of lockdown and social distancing restrictions, which have been widely carried out as policy choice to curb the ongoing COVID-19 pandemic…
A Data-Driven Network Model for the Emerging COVID-19 Epidemics in Wuhan, Toronto and Italy
Ling Xue, Shuanglin Jing, Joel C. Miller +5
The ongoing Coronavirus Disease 2019 (COVID-19) pandemic threatens the health of humans and causes great economic losses. Predictive modelling and forecasting the epidemic trends a…
The spatial-temporal risk index and spreading dynamics for a time-periodic diffusive WNv model
Jing Ge, Zhigui Lin, Huaiping Zhu
This paper is concerned with a simplified epidemic model for West Nile virus in a heterogeneous time-periodic environment. By means of the model, we will explore the impact of spat…
Spatial spreading model and dynamics of West Nile virus in birds and mosquitoes with free boundary
Zhigui Lin, Huaiping Zhu
In this paper, a reaction-diffusion system is proposed to model the spatial spreading of West Nile virus in vector mosquitoes and host birds in North America. Infection dynamics ar…
