Nonlinear mapping between continuous- and discrete-time dynamicsEPL (IF 1.958) Pub Date : 2022-03-01 ,DOI:10.1209/0295-5075/ac5fd0Liang Zhang,Chao-Ran Cai,Ji-Qiang Zhang,Xu-Sheng Liu,Chong-Yang Wang,Zhi-Xi WuAbstract Linear mapping is widely used in dynamic modeling and empirical data analysis, but it suffers from the serious shortcoming that it does not work in the common case of time intervals being large. The fundamental cause of the failure is that the linear mapping does not take into account the coupling effects of multiple events within a discrete time interval. Here, we develop a theoretical framework ...

Multistage onset of epidemics in heterogeneous networksPhysical Review E (IF 2.707) Pub Date : 2021-03-26 ,DOI:10.1103/physreve.103.032313Chao-Ran Cai, Zhi-Xi Wu, Petter Holme
We develop a theory for the susceptible-infected-susceptible (SIS) epidemic model on networks that incorporate both network structure and dynamic correlations. This theory can account for the multistage onset of the epidemic phase in scale-free networks. This phenomenon is characterized by multiple peaks in the susceptibility as a function of the infection rate. It can be explained by that, even under

Optimal organization of functional connectivity networks for segregation and integration with large scale critical dynamics in human brainsFrontiers in Computational Neuroscience (IF 3.387) Pub Date : 2021-02-23 ,DOI:10.3389/fncom.2021.641335Xinchun Zhou, Ningning Ma, Benseng Song, Zhixi Wu, Guangyao Liu, Liwei Liu, Lianchun Yu, Jianfeng Feng
The optimal organization for functional segregation and integration in brain is made evident by the “small-world” feature of functional connectivity (FC) networks, and is further supported by the loss of this feature that has been described in many types of brain disease. However, it remains unknown how such optimally organized FC networks arise from the brain’s structural constrains. On the other
