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...
Recurrent host mobility in spatial epidemics: beyond reaction-diffusion
beyond reaction-diffusion spatial epidemics
2011/9/2
Human mobility is a key factor in spatial disease dynamics and related phenomena. In computational models host mobility is typically modeled by diffusion in space or onmetapolulation networks. Alterna...
Harmonic analysis of spherical sampling in diffusion MRI
Harmonic analysis spherical sampling diffusion MRI
2011/9/9
In the last decade diffusion MRI has become a powerful tool to non-invasively study white-matter integrity in the brain. Recently many research groups have focused their attention on multi-shell spher...
Predictability of extreme events in a branching diffusion model
extreme events branching diffusion model
2010/4/6
We propose a framework for studying predictability of extreme events in complex systems. Major conceptual elements -- hierarchical structure, spatial dynamics, and external driving -- are combined in ...
Analysis of instabilities and pattern formation in time fractional reaction-diffusion systems
instabilities pattern formation time fractional reaction-diffusion systems
2010/4/6
We analyzed conditions for Hopf and Turing instabilities to occur in two-component fractional reaction-diffusion systems. We showed that the eigenvalue spectrum and fractional derivative order mainly ...
Static- and Dynamical-Phase Transition in One-Dimensional Reaction-Diffusion Systems with Boundaries
Static- and Dynamical-Phase Transition One-Dimensional Reaction-Diffusion Systems Boundaries
2010/10/28
A general system of particles (of one or several species) on a one dimensional lattice with boundaries is considered. Two general behaviors of such systems are investigated. The stationary behavior of...
