    • Temporal percolation in activity-driven networks 

      Starnini, Michele; Pastor Satorras, Romualdo (2014-03-14)
      Article
      Accés obert
      We study the temporal percolation properties of temporal networks by taking as a representative example the recently proposed activity-driven-network model [N. Perra et al., Sci. Rep. 2, 469 ( 2012)]. Building upon an ...

      Accés obert
      The data revolution experienced by social science has revealed complex patterns of interactions in human dynamics, such as the heterogeneity and burstiness of social contacts. The recently uncovered temporal dimension of ...

    • Topological properties of a time-integrated activity-driven network 

      Starnini, Michele; Pastor Satorras, Romualdo (2013-06)
      Article
      Accés obert
      Here we consider the topological properties of the integrated networks emerging from the activity-driven model, a temporal network model recently proposed to explain the power-law degree distribution empirically observed ...
