Journal ArticleDOI

Geometry and boundary control of pattern formation and competition

TL;DR: In this article, a wavelet-based discrete singular convolution algorithm is employed to provide high-precision numerical solutions for the formation and competition of cellular ordered state patterns in a confined circular domain, where the Cahn-Hilliard equation is solved with zero-flux boundary condition to describe the phase separation of binary mixtures.
Journal ArticleDOI

Formation of Modularity in a Model of Evolving Networks

TL;DR: A dynamical model describing the evolution of a social network is set up and a link-creating/deleting strategy according to the local dynamics in the model is introduced, finding that for a small coupling strength, the networked system cannot reach any synchronization and the network topology is homogeneous.
Journal ArticleDOI

Dynamical formation of stable irregular transients in discontinuous map systems.

TL;DR: This paper investigates the dynamical formation of stable irregular transients in coupled discontinuous map systems and finds that the transient dynamics has a hidden pattern in the phase space: it repeatedly approaches a basin boundary and then jumps from the boundary to a remote region in thephase space.
Journal ArticleDOI

Characterizing generalized synchronization in complex networks

TL;DR: Direct evidence is provided demonstrating that node dynamics in a network in a chaotic GS state can indeed achieve functional relations, although they may not directly connect to each other in typical complex networks.
Journal ArticleDOI

Analysis of traffic flow on complex networks

TL;DR: A new routing strategy for controlling packet routing on complex networks where the delivery capability of each node is adopted as a piece of local information to be integrated with the load traffic dynamics to weight the next route.
