Irreducible network backbones: unbiased graph filtering via maximum entropy

Alessio Vincenzo Cardillo

Networks provide an informative, yet non-redundant description of complex systems only if links represent truly dyadic relationships that cannot be directly traced back to node-specific properties such as size, importance, or coordinates in some embedding ...

Path to AWAKE: Evolution of the concept

Yiming Li, Hua Zhang, Gennady Plyushchev, Shuai Liu, Frank Zimmermann

This paper describes the conceptual steps in reaching the design of the AWAKE experiment currently under construction at CERN. We start with an introduction to plasma wakefield acceleration and the motivation for using proton drivers. We then describe the ...

Distributed rate allocation in switch-based multiparty videoconference

Pascal Frossard, Sergio Mena, Stefano D'Aronco

Multiparty videoconferences, or more generally multiparty video calls, are gaining a lot of popularity as they offer a rich communication experience. These applications have however, large requirements in terms of both network and computational resources a ...

Resilience To Contagion In Financial Networks

Léo Hamed Amini

We derive rigorous asymptotic results for the magnitude of contagion in a large counterparty network and give an analytical expression for the asymptotic fraction of defaults, in terms of network characteristics. Our results extend previous studies on cont ...

The Trajectories Tool: Amplifying Network Visualization Complexity

Alexandre André Robert Rigal, Dario Rodighiero, Loup Cellard

Network visualizations are the most complex visualizations possible, but sometimes they are not capable of describing system-complexity. Even if they are the most widely employed visualization techniques, they still have limitations. Indeed a) their relati ...

Epidemics in Venice: On the Small or Large Nature of the Pre-modern World

Giovanni Colavizza

Marvel et al. [12] recently argued that the pre-modern contact world was physically and, by set inclusion, socially not small-world. Since the Black Death and similar plagues used to spread in well-defined waves, the argument goes, the underlying contact n ...

Exploring Citation Networks to Study Intertextuality in Classics

Matteo Romanello

Referring constitutes such an essential scholarly activity across disciplines that it has been regarded by [Unsworth 2000] as one of the scholarly primitives. In Classics, in particular, the references to passages of the ancient texts - the so-called canon ...

Geomorphic controls on elevational gradients of species richness

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Francesco Carrara, Florian Altermatt

Elevational gradients of biodiversity have been widely investigated, and yet a clear interpretation of the biotic and abiotic factors that determine how species richness varies with elevation is still elusive. In mountainous landscapes, habitats at differe ...

Enforcing Efficient Equilibria in Network Design Games via Subsidies

Christos Kalaitzis

The efficient design of networks has been an important engineering task that involves challenging combinatorial optimization problems. Typically, a network designer has to select among several alternatives which links to establish so that the resulting net ...
