Swarming transitions in hierarchical societies
Tingting Xue, Xu Li, Peter Grassberger +1
Social hierarchy is central to decision-making in the coordinated movement of many swarming species. Here we propose a hierarchical swarm model in the spirit of the Vicsek model of…
Network synchronization with periodic coupling
Sansan Li, Na Sun, Li Chen +1
The synchronization behavior of networked chaotic oscillators with periodic coupling is investigated. It is observed in simulations that the network synchronizability could be sign…
Pattern dynamics of interacting contagions
Li Chen
The spread of infectious diseases, rumors, fashions, innovations are complex contagion processes, embedded both in networked and spatial contexts. Here we investigate the pattern d…
Fundamental properties of cooperative contagion processes
Li Chen, Fakhteh Ghanbarnejad, Dirk Brockmann
We investigate the effects of cooperativity between contagion processes that spread and persist in a host population. We propose and analyze a dynamical model in which individuals…
Phase Transitions in Cooperative Coinfections: Simulation Results for Networks and Lattices
Peter Grassberger, Li Chen, Fakhteh Ghanbarnejad +1
We study the spreading of two mutually cooperative diseases on different network topologies, and with two microscopic realizations, both of which are stochastic versions of an SIR…
Adaptive network models of collective decision making in swarming systems
Li Chen, Cristián Huepe, Thilo Gross
We consider a class of adaptive network models where links can only be created or deleted between nodes in different states. These models provide an approximate description of a se…
Outbreaks of coinfections: the critical role of cooperativity
Li Chen, Fakhteh Ghanbarnejad, Weiran Cai +1
Modeling epidemic dynamics plays an important role in studying how diseases spread, predicting their future course, and designing strategies to control them. In this letter, we int…
