The spatial structure of large-scale online social networks has been largely unaccessible
due to the lack of available and accurate data about people's location. However, with the …

This book discusses the study and analysis of the physical aspects of social systems and
models, inspired by the analogy with familiar models of physical systems and possible …

Complex networks have gained much attention in the past 20 years, with thousands of
publications due to their broad interest and applicability. Studies initially focused on the …

Communication of signals among nodes in a complex network poses fundamental problems
of efficiency and cost. Routing of messages along shortest paths requires global information …

Real data show that interdependent networks usually involve intersimilarity. Intersimilarity
means that a pair of interdependent nodes have neighbors in both networks that are also …

Robustness of two coupled networks systems has been studied separately only for
dependency coupling [Buldyrev, Nature (London) 464, 1025 (2010) NATUAS 0028-0836 …

Common sense suggests that networks are not random mazes of purposeless connections,
but that these connections are organized so that networks can perform their functions well …

Human mobility is investigated using a continuum approach that allows to calculate the
probability to observe a trip to any arbitrary region, and the fluxes between any two regions …

We investigate the synapse-resolution connectomes of fruit flies across different
developmental stages, revealing a consistent scaling law in neuronal connection probability …

We introduce a strategy of navigation in undirected networks, including regular, random, and
complex networks, that is inspired by Lévy random walks, generalizing previous navigation …
