A New Coupled Awareness-Epidemic Spreading Model with Neighbor Behavior on Multiplex Networks by Chao Zuo, Anjing Wang, Fenping Zhu, Zeyang Meng, Xueke Zhao

“…In this paper, we propose a nonlinear coupled model to study the two interacting processes of awareness diffusion and epidemic spreading on the same individual who is affected by different neighbor behavior status on multiplex networks. We achieve this topology scenario by two kinds of factors, one is the perception factor that can change interplay between different layers of networks and the other is the neighbors’ behavior status that can change the infection rate in each layer. …”
