This paper focuses on human behavior in web surfing during the special stage called Flash Crowd (FC) period. Some statistical properties of human behavior are investigated. A moving approximate entropy (ApEn) method is provided to precisely locate the FC stage at first. Then the multiscale...

With the rapid development of the Internet and the promotion of mobile Internet, microblogs have become a major source and route of transmission for public opinion, including burst topics that are caused by emergencies. To facilitate real time mining of a large range of burst topics, in this...

This paper considers a non-autonomous competitive two-species model with stage structure in one species. The conditions of permanence obtained. Furthermore, the existence and asymptotic stability of the periodic solution are proved under some assumptions if this model turns out to be a periodic...

The small-world property, vertices are highly clustered yet the path length between them is small, has been widely studied in unweighted graphs. In many real-world networks, the connections have associated weights that represent the strength of the interactions among vertices. This important...

Three types of two bright bound solitons with increasing coherence are investigated in the Bose–Einstein condensates (BECs) with the exponentially time-dependent interparticle interaction in an expulsive parabolic potential. Two methods are provided with symbolic computation to improve the...
