Complex Networks Collaboratory             





Welcome to the CX-NETS web-site. This is the virtual collaboratory of three research groups that despite their far apart geographical locations pursue the same research agenda in close collaboration. The web-site is also intended as an information exchange points with links to conferences, tools and references useful for the network science community.

Research keywords: Complex networks, Internet, WWW, Epidemic modeling, Large-scale infrastructures, non-equilibrium statistical physics, complex systems, self-organization.

Phase transitions in contagion processes mediated by recurrent mobility patterns
D. Balcan, A. Vespignani

Nature Physics 7: 581-586 (2011)

Phase transition in susceptible-infected-recovered epidemics mediated by US commuting flows. A phase transition takes place as we vary a global scaling factor of the commuting rates. In the subcritical regime only a small fraction of counties get infected while in the supercritical regime an appreciable fraction experiences the disease outbreak. The maps illustrate these regimes by projecting the cumulative number of infected cases. Simulations start with a small number of infected persons in Los Angeles County.
