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 …

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 …

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 …

The mathematical study of the small-world concept has fostered quite some interest, showing
that small-world features can be identified for some abstract classes of networks. However, …

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 …

The North American power grid is one of the most complex technological networks, and its
interconnectivity allows both for long-distance power transmission and for the propagation of …

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

Complex networks have been successfully used to describe the spread of diseases in
populations of interacting individuals. Conversely, pairwise interactions are often not enough to …

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 …

Networks constitute the backbone of complex systems, from the human brain to computer
communications, transport infrastructures to online social systems and metabolic reactions to …
