多重网络中信息和病毒交互传播研究
Interplay between epidemic spreading and information spreading in multiplex networks

病毒传播过程中，通常伴随着“病毒存在且正在蔓延”的信息传播，而且信息传播机制不同于病毒传播机制。文中利用连续时间马尔科夫过程，描述多重网络中病毒传播和信息传播相互关联动力学，研究信息传播动力学对病毒传播的影响，推导多重网络中的病毒传播阈值。文中方法不仅能够描述社会接触网络中的病毒传播过程，而且能够描述社交网络中的信息传播过程。研究表明，病毒传播阈值不仅与社交网络结构相关，而且与社交网络中的信息传播动力学相关。
Epidemic spreading usually accompanies with the dissemination of information, and the diffusion mechanism of information is different from propagation mechanism of diseases. Based on the continuous time Markov chain process, a new epidemic model for the information spreading in multiple networks is proposed to study the interplay between information spreading and epidemic spreading. The process of epidemic spreading is described in social contact networks, and the cycle process of information spreading is simulated in social networks. The epidemic threshold associated with information spreading is derived in multiple networks. The study shows that the epidemic threshold depends on dynamics of information spreading and the network structure in social networks
