Opinion formation in time-varying social networks: The case of Naming Game
Opinion formation time-varying social networks The case of Naming Game Social and Information Networks
2012/4/19
We study the dynamics of the Naming Game as an opinion formation model on time-varying social networks. This agent-based model captures the essential features of the agreement dynamics by means of a m...
Epidemic Variability in Hierarchical Geographical Networks with Human Activity Patterns
Epidemic Variability Hierarchical Geographical Networks Human Activity Patterns Social and Information Networks
2012/4/19
Recently, some studies have revealed that non-Poissonian statistics of human behaviors stem from the hierarchical geographical network structure. On this view, we focus on epidemic spreading in the hi...
Variability of Contact Process in Complex Networks
Variability of Contact Process Complex Networks Social and Information Networks
2012/4/19
We study numerically how the structures of distinct networks influence the epidemic dynamics in contact process. We first find that the variability difference between homogeneous and heterogeneous net...
A constitutive law for cross-linked actin networks by homogenization techniques
A-microstructure B-biological material B-constitutive behavior
2010/11/22
Inspired by experiments on the actin driven propulsion of micrometer sized beads we develop and study a minimal mechanical model of a two-dimensional network of stiff elastic filaments grown from the ...
Shift of percolation thresholds for epidemic spread between static and dynamic small-world networks
percolation thresholds epidemic spread static dynamic small-world networks
2010/11/16
The aim of the study was to compare the epidemic spread on static and dynamic small-world networks. The network was constructed as a 2-dimensional Watts-Strogatz model (500x500 square lattice with ad...
Contact processes and moment closure on adaptive networks
Contact processes adaptive networks
2010/11/16
Contact processes describe the transmission of distinct properties of nodes via the links of a network. They provide a simple framework for many phenomena, such as epidemic spreading and opinion forma...
Principles of Physical Layer Security in Multiuser Wireless Networks: A Survey
Principles of Physical Layer Security Multiuser Wireless Networks
2010/11/22
This paper provides a comprehensive review of the domain of physical layer security for wireless communications. The essential premise of physical-layer security is to enable the exchange of confiden...
Time scales of epidemic spread and risk perception on adaptive networks
epidemic spread risk perception adaptive networks
2010/11/16
Incorporating dynamic contact networks and delayed awareness into a contagion model with memory, we study the spreading patterns of infectious diseases in connected populations. It is found that the ...
Evolution of Coordination in Social Networks: A Numerical Study
Social Networks Numerical Study
2010/11/16
Coordination games are important to explain efficient and desirable social behavior. Here we study these games by extensive numerical simulation on networked social structures using an evolutionary a...
