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...

Exhibiting Time-Varying Nuclear Decay Rates Systematic Effects
2011/7/20
Since the 1930s, and with very few exceptions, it has been assumed that the process of radioactive decay is a random process, unaffected by the environment in which the decaying nucleus resides. There...
Real complex systems are inherently time-varying. Thanks to new communication systems and novel technologies, it is today possible to produce and analyze social and biological networks with detailed i...
