    Recovery rate affects the effective epidemic threshold with synchronous updating

    Shu, Panpan ; Wang, Wei ; Tang, Ming ; Zhao, Pengcheng ; Zhang, Yi-Cheng

    Accurate identification of effective epidemic threshold is essential for understanding epidemic dynamics on complex networks. In this paper, we systematically study how the recovery rate affects the susceptible-infected-removed spreading dynamics on complex networks, where synchronous and asynchronous updating processes are taken into account. We derive the theoretical effective epidemic...

    Dynamics of social contagions with limited contact capacity

    Wang, Wei ; Shu, Panpan ; Zhu, Yu-Xiao ; Tang, Ming ; Zhang, Yi-Cheng

    In: Chaos: An Interdisciplinary Journal of Nonlinear Science, 2015, vol. 25, no. 10, p. 103102

    Individuals are always limited by some inelastic resources, such as time and energy, which restrict them to dedicate to social interaction and limit their contact capacities. Contact capacity plays an important role in dynamics of social contagions, which so far has eluded theoretical analysis. In this paper, we first propose a non-Markovian model to understand the effects of contact capacity on...
