标题： Effects of awareness diffusion and self-initiated awareness behavior on epidemic spreading - an approach based on multiplex networks

摘要： 在本文中，我们研究了多层网络中流行病传播与意识扩散之间的相互作用。 在该模型中，一种传染病可以在一个代表流行病传播路径的网络（接触网络）中传播，导致另一个网络（信息网络）中的意识扩散，然后意识的扩散会使个体采取社交距离，这反过来又会影响流行病的传播。 关于意识的扩散，我们假设，一方面，个体可以通过信息网络中的其他有意识邻居获得信息，另一方面，易感个体可以由接触网络中的感染邻居（局部信息）或大众媒体（全局信息）引发自我意识。 通过马尔可夫链方法和数值计算，我们发现感染个体的密度和流行病阈值会受到两个网络结构和意识有效传播率的影响。 然而，我们证明尽管引入自我意识可以降低感染密度，但无论是在局部信息还是全局信息的情况下，都不能提高流行病阈值。 我们的发现与许多先前的结果显著不同——基于局部信息的行为反应可以改变流行病阈值。 显示英文摘要

摘要： In this paper, we study the interplay between the epidemic spreading and the diffusion of awareness in multiplex networks. In the model, an infectious disease can spread in one network representing the paths of epidemic spreading (contact network), leading to the diffusion of awareness in the other network (information network), and then the diffusion of awareness will cause individuals to take social distances, which in turn affects the epidemic spreading. As for the diffusion of awareness, we assume that, on the one hand, individuals can be informed by other aware neighbors in information network, on the other hand, the susceptible individuals can be self-awareness induced by the infected neighbors in the contact networks (local information) or mass media (global information). Through Markov chain approach and numerical computations, we find that the density of infected individuals and the epidemic threshold can be affected by the structures of the two networks and the effective transmission rate of the awareness. However, we prove that though the introduction of the self-awareness can lower the density of infection, which cannot increase the epidemic threshold no matter of the local information or global information. Our finding is remarkably different to many previous results--local information based behavioral response can alter the epidemic threshold.
