Structural Analysis of Laplacian Spectral Properties with Application to Electric Transmission Networks
Laplacian Spectral Properties Electric Transmission Networks Optimization and Control
2011/8/18
Abstract: The spectrum of the Laplacian matrix of a network plays a key role in a wide range of dynamical problems associated with the network, from transient stability analysis of power networks to d...
Mandelbrot Law of Evolving Networks
Mandelbrot Law Evolving Networks Degree distributions power-law exponent
2011/8/11
Abstract: Degree distributions of many real networks are known to follow the Mandelbrot law, which can be considered as an extension of the power law that determined by not only the power-law exponent...
Exploring complex networks via topological embedding on surfaces

2011/10/8
Abstract: We demonstrate that graphs embedded on surfaces are a powerful and practical tool to generate, characterize and simulate networks with a broad range of properties. Remarkably, the study of t...

Decorrelation by recurrent inhibition in randomly and strongly coupled networks
recurrent inhibition decorrelation Neurons and Cognition
2011/10/8
Abstract: I calculate the mean pairwise correlation between neurons in a network model characterized by strong and random interactions. The mean is calculated with respect to both temporal fluctuation...
Controllability of Complex Networks with Nonlinear Dynamics
Complex Networks Nonlinear Dynamics
2011/8/16
Abstract: The controllability of large linear network systems has been addressed recently [Liu et al. Nature (London), 473, 167 (2011)]. We investigate the controllability of complex-network systems w...
Uncovering Evolutionary Ages of Nodes in Complex Networks
Uncovering Evolutionary Ages Nodes Complex Networks
2011/8/3
Abstract: In a complex network, different groups of nodes may have existed for different amounts of time. To detect the evolutionary history of a network is of great importance. We present a general m...
Invariants of Spin Networks from Braided Ribbon Networks
Spin Networks Braided Ribbon Networks General Relativity and Quantum Cosmology
2011/7/26
Abstract: We connect Braided Ribbon Networks to the states of loop quantum gravity. Using this connection we present the reduced link as an invariant which captures information from the embedding of t...

Braided Ribbon Networks evolution move General Relativity and Quantum Cosmology
2011/7/26
Abstract: We present a consistent definition for braided ribbon networks in 3-dimensional manifolds, unifying both three and four valent networks in a single framework. We present evolution moves for ...
We study the dynamics of the voter and Moran processes running on top of complex network
substrates where each edge has a weight depending on the degree of the nodes it connects. For
each elementary...
A evolutionary method for finding communities in bipartite networks
evolutionary method bipartite networks
2010/11/16
Common practice in community structure detection is to develop different methods for different classes of networks. Here, we first show that unipartite networks and directed networks can be uniformly...
Being Rational or Aggressive? A Revisit to Dunbar's Number in Online Social Networks
Being Rational Dunbar's Number Social Networks
2010/11/17
Recent years have witnessed the explosion of online social networks (OSNs). They provide powerful IT-innovations for online social activities such as organizing contacts, publishing contents, and shar...
Networks of Economic Market Interdependence and Systemic Risk
Economic Market Interdependence Systemic Risk
2010/11/18
The dynamic network of relationships among corporations underlies cascading economic failures including the current economic crisis, and can be inferred from correlations in market value fluctuations....
A Framework for Quantitative Analysis of Cascades on Networks
Quantitative Analysis Cascades on Networks
2010/11/18
How does information flow in online social networks? How does the structure and size of the information cascade evolve in time? How can we efficiently mine the information contained in cascade dynami...
The results of local measurements on some composite quantum systems cannot be reproduced classically. This impossibility, known as quantum nonlocality, represents a milestone in the foundations of qua...
