Coupled biological and chemical systems, neural networks, social interacting species, the
Internet and the World Wide Web, are only a few examples of systems composed by a large …

The complexity of many biological, social and technological systems stems from the richness
of the interactions among their units. Over the past decades, a variety of complex systems …

Complex networks have become the main paradigm for modelling the dynamics of interacting
systems. However, networks are intrinsically limited to describing pairwise interactions, …

We introduce the concept of efficiency of a network as a measure of how efficiently it exchanges
information. By using this simple measure, small-world networks are seen as systems …

Large but rare cascades triggered by small initial shocks are present in most of the
infrastructure networks. Here we present a simple model for cascading failures based on the …

The network metaphor in the analysis of urban and territorial cases has a long tradition,
especially in transportation or land-use planning and economic geography. More recently, urban …

The small-world phenomenon has been already the subject of a huge variety of papers,
showing its appeareance in a variety of systems. However, some big holes still remain to be filled…

The application of the network approach to the urban case poses several questions in terms
of how to deal with metric distances, what kind of graph representation to use, what kind of …

We study centrality in urban street patterns of different world cities represented as networks
in geographical space. The results indicate that a spatial analysis based on a set of four …

… In this paper we use the dynamical approach of the Crucitti-Latora-Marchiori (CLM) model
of reference [16], adapting it to our network. We assume that each generator transfers power …
