On the structure of competitive societies
Ben-Naim, E.; Vazquez, F.; Redner, S. - In: The European Physical Journal B - Condensed Matter and … 49 (2006) 4, pp. 531-538
We model the dynamics of social structure by a simple interacting particle system. The social standing of an individual agent is represented by an integer-valued fitness that changes via two offsetting processes. When two agents interact one advances: the fitter with probability p and the less...

The power of choice in growing trees
D'Souza, R. M.; Krapivsky, P. L.; Moore, C. - In: The European Physical Journal B - Condensed Matter and … 59 (2007) 4, pp. 535-543
The “power of choice” has been shown to radically alter the behavior of a number of randomized algorithms. Here we explore the effects of choice on models of random tree growth. In our models each new node has k randomly chosen contacts, where k 1 is a constant. It then attaches to...

Can a few fanatics influence the opinion of a large segment of a society?
Stauffer, D.; Sahimi, M. - In: The European Physical Journal B - Condensed Matter and … 57 (2007) 2, pp. 147-152
Models that provide insight into how extreme positions regarding any social phenomenon may spread in a society or at the global scale are of great current interest. A realistic model must account for the fact that globalization, internet, and other means of mass communications have given rise to...

A multichannel shot noise approach to describe synaptic background activity in neurons

Systems driven by Poisson-distributed quantal inputs can be described as “shot noise” stochastic processes. This … longer be described by classical shot noise processes. Here, we show that explicit expressions for various statistical … temporal correlations and the statistics of fluctuations. Multi-channel shot noise processes, therefore, open a way to deduce …
