Delia Mocanu, Andrea Baronchelli, Bruno Gonçalves +2
Large scale analysis and statistics of socio-technical systems that just a few short years ago would have required the use of consistent economic and human resources can nowadays b…
Motion-induced synchronization in metapopulations of mobile agents
Jesús Gómez-Gardeñes, Vincenzo Nicosia, Roberta Sinatra +1
We study the influence of motion on the emergence of synchronization in a metapopulation of random walkers moving on a heterogeneous network and subject to Kuramoto interactions at…
Contagion dynamics in time-varying metapopulation networks
Suyu Liu, Andrea Baronchelli, Nicola Perra
The metapopulation framework is adopted in a wide array of disciplines to describe systems of well separated yet connected subpopulations. The subgroups or patches are often repres…
