    • Characterization and modeling of weighted networks 

      Barthelemy, M; Barrat, A; Pastor Satorras, Romualdo; Vespignani, Alessandro (2005-01)
      Article
      Restricted access - publisher's policy
      We review the main tools which allow for the statistical characterization of weighted networks. We then present two case studies, the airline connection network and the scientific collaboration network which are representatives ...
    • Dynamical patterns of epidemic outbreaks in complex heterogeneous networks 

      Barthelemy, M; Barrat, A; Pastor Satorras, Romualdo; Vespignani, Alessandro (2005-03-10)
      Article
      Open Access
      We present a thorough inspection of the dynamical behavior of epidemic phenomena in populations with complex and heterogeneous connectivity patterns. We show that the growth of the epidemic prevalence is virtually instantaneous ...
    • The architecture of complex weighted networks 

      Barrat, A; Barthelemy, M; Pastor Satorras, Romualdo; Vespignani, Alessandro (2004-03-16)
      Article
      Open Access
      Networked structures arise in a wide array of different contexts such as technological and transportation infrastructures, social phenomena, and biological systems. These highly interconnected systems have recently been ...
    • Velocity and hierarchical spread of epidemic outbreaks in scale-free networks 

      Barthelemy, M; Barrat, A; Pastor Satorras, Romualdo; Vespignani, Alessandro (American Institute of Physics (AIP), 2004-04-30)
      Article
      Open Access
      We study the effect of the connectivity pattern of complex networks on the propagation dynamics of epidemics. The growth time scale of outbreaks is inversely proportional to the network degree fluctuations, signaling that ...
