We study the realizability of scale free-networks with a given degree sequence, showing that the fraction of realizable sequences undergoes two first-order transitions at the values 0 and 2 of the pow...
Assessing the consistency of community structure in complex networks
community structure complex networks
2011/9/9
In recent years, community structure has emerged as a key component of complex network analysis.As more data has been collected, researchers have begun investigating changing community structure acros...
On the Non-Progressive Spread of Influence through Social Networks
Non-Progressive Social Networks
2011/9/14
The spread of in uence in social networks is studied in two main categories: the progressive model and the non-progressive model (see e.g. the seminal work of Kempe, Kleinberg, and Tardos in KDD 2003)...
Nodal dynamics determine the controllability of complex networks
Nodal dynamics complex networks controllability
2011/9/1
Structural controllability has been proposed as an analytical framework for making predictions regarding the control of complex networks across myriad disciplines in the physical and life sciences (Lu...
Simple rules govern finite-size effects in scale-free networks
finite-size effects scale-free networks
2011/9/2
We give an intuitive though general explanation of the finitesize effect in scale-free networks in terms of the degree distribution of the starting network. This result clarifies the relevance of the ...
Redundancy and cooperativity in the mechanics of compositely crosslinked filamentous networks
filamentous networks Redundancy and cooperativity
2011/9/14
The actin cytoskeleton in living cells has many types of crosslinkers. The mechanical interplay between these different crosslinker types is an open issue in cytoskeletal mechanics. We develop a frame...
Optimizing and controlling functions of complex networks by manipulating rich-club connections
Optimizing and controlling functions complex networks rich-club connections
2011/9/6
Traditionally, there is no evidence suggesting that there are strong ties between the rich-club property and the function of complex networks. In this study, we find that whether a very small portion ...
Understanding how far information, behaviors, or pathogens spread in social networks is an important problem, having implications for both predicting the size of epidemics, as well as for planning e e...
The strength of strong ties in scientific collaboration networks
scientific collaboration networks
2011/9/6
Network topology and its relationship to tie strengths may hinder or enhance the spreading of information in social networks. We study the correlations between tie strengths and topology in networks o...
A Game Theoretical Approach to Broadcast Information Diffusion in Social Networks
Social Network, Game Theory, Knowledge,Popularity, Trust, Reputation, Rumor.
2011/9/15
One major function of social networks (e.g., massive online social networks) is the dissemination of information, such as scientific knowledge, news, and rumors. Information can be propagated by the u...
Modeling Social Networks with Node Attributes using the Multiplicative Attribute Graph Model
Modeling Social Networks Node Multiplicative Attribute Graph Model
2011/9/15
Networks arising from social, technological and natural domains exhibit rich connectivity patterns and nodes in such networks are often labeled with attributes or features. We address the question of ...
Percolation in Interdependent and Interconnected Networks: Abrupt Change from Second to First Order Transition
Cascading failures, Percolation, Coupled networks, Phase transition
2011/9/5
Robustness of two coupled networks system has been studied only for dependency coupling (S. Buldyrev et. al., Nature, 2010) and only for connectivity coupling (E. A. Leicht and R. M. D’Souza, arxiv:09...
Unified mean-field approach to voter-like models on networks
Complex networks -Ordering dynamics -Voter models-Mean-field theory
2011/9/5
We propose a generalized framework for the study of voter models in complex networks at the the heterogeneous mean-field (HMF) level that (i) yields a unified picture for existing copy/invasion proces...
Co-evolution of Selection and Influence in Social Networks
Selection and Influence Social Networks
2011/9/14
Many networks are complex dynamical systems, where both attributes of nodes and topology of the network(link structure) can change with time. We propose a
model of co-evolving networks where both nod...
Resolving Author Name Homonymy to Improve Resolution of Structures in Co-author Networks
Improve Resolution Co-author Networks
2011/9/13
We investigate how author name homonymy distorts clustered large-scale co-author networks, and present a simple, e ective, scal-able and generalizable algorithm to ameliorate such distortions. We eval...
