Statistical physics has proven to be a fruitful framework to describe phenomena outside the
realm of traditional physics. Recent years have witnessed an attempt by physicists to study …

Inspired by empirical studies of networked systems such as the Internet, social networks,
and biological networks, researchers have in recent years developed a variety of techniques …

From the Internet to networks of friendship, disease transmission, and even terrorism, the
concept--and the reality--of networks has come to pervade modern society. But what exactly …

Complex networks such as the Internet, WWW, transportation networks, power grids,
biological neural networks, and scientific cooperation networks of all kinds provide …

In Deffuant et al.(J. Artif. Soc. Soc. Simulation 5 (2002) 4), we proposed a simple model of
opinion dynamics, which we used to simulate the influence of extremists in a population …

Social influence plays an important role in human behavior and decisions. Sources of
influence can be divided as external, which are independent of social context, or as …

Noise is omnipresent in biomedical systems and signals. Conventional views assume that
its presence is detrimental to systems' performance and accuracy. Hence, various analytic …

We study numerically the ordering process of two very simple dynamical models for a two-
state variable on several topologies with increasing levels of heterogeneity in the degree …

In this paper, we analyze web-downloaded data on people sharing their music library, that
we use as their individual musical signatures. The system is represented by a bipartite …
