In this talk, I will present a collection of results focusing on the presence of inhomogeneities in networks: from the detection of dense clusters (community [...]

Recent results have characterized the exact information-theoretic threshold for graph matching in correlated Erd?s-Rényi graphs. However, very little is known about the existence of efficient [...]

Money or data transfers, contacts between individuals, or product sales, may all be modeled as temporal interactions. Studying the structure and dynamics of interactions is [...]

Open web proxies promise anonymity and censorship circumvention at no cost. Several websites publish lists of free proxies organized by country, anonymity level, and performance. [...]

Confinement of human settlement in areas limited in size is the foundation of the long-standing Central Place Theory which assumes the existence of regular spatial [...]

We propose a novel algorithm for the hierarchical clustering of graphs. The algorithm is a simple but key modification of the Louvain algorithm based on [...]

In many applications such as cloud computing, managing server farm resources etc. an incoming task or job has to be matched with an appropriate server [...]

Next generation wireless architectures are expected to enable slices of shared wireless infrastructure which are customized to specific mobile operators/services. Given infrastructure costs and the [...]
