Synchronization on Effective Networks (2009)
Zhou, Tao, Zhao, Ming, Zhou, Changsong
The study of network synchronization has attracted increasing attention recently. In this paper, we strictly define a class of networks, namely effective networks, which are synchronizable and...
Mapping from Architecture to Dynamics: A Unified View of Dynamical Processes on Networks (2009)
Zhang, Jie, Zhou, Changsong, Xu, Xiaoke, Small, Michael
Although it is unambiguously agreed that structure plays a fundamental role in shaping the dynamics of complex systems, this intricate relationship still remains unclear. We investigate a general...
Optimal transport on supply-demand networks (2009)
Chen, Yu-Han, Wang, Bing-Hong, Zhao, Li-Chao, Zhou, Changsong, Zhou, Tao
Previously, transport networks are usually treated as homogeneous networks, that is, every node has the same function, simultaneously providing and requiring resources. However, some real networks,...
Effective leadership in competition (2009)
Zhang, Hai-Tao, Wang, Ning, Chen, Michael Z. Q., Zhou, Tao, Zhou, Changsong
Among natural biological flocks/swarms or even mass social activities, when the collective behaviors of the followers has been dominated by the moving direction or opinion of one leader group, it...
Synchronization in complex networks (2008)
Arenas, Alex, Diaz-Guilera, Albert, Kurths, Jurgen, Moreno, Yamir, Zhou, Changsong
Synchronization processes in populations of locally interacting elements are in the focus of intense research in physical, biological, chemical, technological and social systems. The many efforts...
Reciprocity of Networks with Degree Correlations and Arbitrary Degree Sequences (2007)
Zlatić, Vinko, Zhou, Changsong, Štefančić, Hrvoje, Kurths, Jürgen
Although most of the real networks contain a mixture of directed and bidirectional (reciprocal) connections, the reciprocity $r$ has received little attention as a subject of theoretical...
Universality in the synchronization of weighted random networks (2006)
Zhou, Changsong, Motter, Adilson E., Kurths, Jurgen
Realistic networks display not only a complex topological structure, but also a heterogeneous distribution of weights in the connection strengths. Here we study synchronization in weighted complex...
Weighted networks are more synchronizable: how and why (2005)
Motter, Adilson E., Zhou, Changsong, Kurths, Juergen
Most real-world networks display not only a heterogeneous distribution of degrees, but also a heterogeneous distribution of weights in the strengths of the connections. Each of these heterogeneities...
Network Synchronization, Diffusion, and the Paradox of Heterogeneity (2005)
Motter, Adilson E., Zhou, Changsong, Kurths, Juergen
Many complex networks display strong heterogeneity in the degree (connectivity) distribution. Heterogeneity in the degree distribution often reduces the average distance between nodes but,...
Enhancing complex-network synchronization (2004)
Motter, Adilson E., Zhou, Changsong, Kurths, Juergen
Heterogeneity in the degree (connectivity) distribution has been shown to suppress synchronization in networks of symmetrically coupled oscillators with uniform coupling strength (unweighted...
Synchronization and oscillator death in oscillatory media with stirring (2003)
Neufeld, Zoltan, Kiss, Istvan Z., Zhou, Changsong, Kurths, Juergen
The effect of stirring in an inhomogeneous oscillatory medium is investigated. We show that the stirring rate can control the macroscopic behavior of the system producing collective oscillations...
Coherence resonance near blowout bifurcation in nonlinear dynamical systems (2000)
Previous studies have shown that noise can induce coherence resonance in some nonlinear dynamical systems close to a bifurcation of a periodic motion, such as in excitable systems. We demonstrate...
Nonlinear dynamical systems possessing an invariant subspace in the phase space and chaotic or stochastic motion within the subspace often display on-off intermittency close to the threshold of...
Nonlinear dynamical systems possessing reflection symmetry have an invariant subspace in the phase space. The dynamics within the invariant subspace can be random or chaotic. As a system parameter...
Robustness of Supersensitivity to Small Signals in Nonlinear Dynamical Systems (2000)
Nonlinear dynamical systems possessing an invariant subspace can display interesting dynamical behavior, such as on-off intermittency and bubbling. This letter shows that a class of such systems have...
Extracting Messages Masked by Chaotic Signals of Time-delay Systems (2000)
We show how to extract messages masked by a chaotic signal of a time-delay system with very high dimension and many positive Lyapunov exponents. Using a special embedding coordinate, the infinite...
Decoding Information by Following Parameter Modulation With Parameter Adaptive Control (2000)
It has been proposed to realize secure communication using chaotic synchronization via transmission of binary message encoded by parameter modulation in the chaotic system. This paper considers the...
Synchronization of Chaotic Maps by Symmetric Common Noise (2000)
Synchronization of identical chaotic systems subjected to common noise has been the subject of recent research. Studies on several chaotic systems have shown that, the synchronization is actually...
Synchronization With Positive Conditional Lyapunov Exponents (2000)
Synchronization of chaotic system may occur only when the largest conditional Lyapunov exponent of the driven system is negative. The synchronization with positive conditional Lyapunov reported in a...
Simple Driven Maps As Sensitive Devices (2000)
Sensitive dependence of nonlinear systems on initial conditions or parameters can be useful in applications. We propose in this paper that bubbling behavior in simple driven symmetrical maps may be...
We study the dynamics of a lattice of coupled nonidentical Fitz Hugh-Nagumo system subject to independent external noise. It is shown that these stochastic oscillators can lead to global...
