    • Aging and percolation dynamics in a Non-Poissonian temporal network model 

      Moinet, Antoine; Starnini, Michele; Pastor Satorras, Romualdo (2016-08-24)
      Article
      Open Access
      We present an exhaustive mathematical analysis of the recently proposed Non-Poissonian Activity Driven (NoPAD) model [Moinet et al., Phys. Rev. Lett. 114, 108701 (2015)], a temporal network model incorporating the empirically ...
    • Burstiness and aging in social temporal networks 

      Moinet, Antoine; Starnini, Michele; Pastor Satorras, Romualdo (2015-03-13)
      Article
      Open Access
      The presence of burstiness in temporal social networks, revealed by a power-law form of the waiting time distribution of consecutive interactions, is expected to produce aging effects in the corresponding time-integrated ...
    • Effects of temporal correlations in social multiplex networks 

      Starnini, Michele; Baronchelli, Andrea; Pastor Satorras, Romualdo (Macmillan Publishers, 2017-08-17)
      Article
      Open Access
      Multi-layered networks represent a major advance in the description of natural complex systems, and their study has shed light on new physical phenomena. Despite its importance, however, the role of the temporal dimension ...
    • Generalized voter-like models on heterogeneous networks 

      Moretti, Paolo; Baronchelli, Andrea; Starnini, Michele; Pastor Satorras, Romualdo (Springer, 2013)
      Part of book or chapter of book
      Restricted access - publisher's policy
      This Chapter presents a generalized model of consensus formation, which is able to encompass all previous formulations of copy/invasion processes inspired by variations on the voter model and the Moran process. It considered ...
    • Immunization strategies for epidemic processes in time-varying contact networks 

      Starnini, Michele; Machens, Anna; Cattuto, Ciro; Barrat, Alain; Pastor Satorras, Romualdo (2013)
      Article
      Open Access
      preading processes represent a very efficient tool to investigate the structural properties of networks and the relative importance of their constituents, and have been widely used to this aim in static networks. Here we ...
    • Model reproduces individual, group and collective dynamics of human contact networks 

      Starnini, Michele; Baronchelli, Andrea; Pastor Satorras, Romualdo (2016-10-01)
      Article
      Open Access
      Empirical data on the dynamics of human face-to-face interactions across a variety of social venues have recently revealed a number of context-independent structural and temporal properties of human contact networks. This ...
    • Modeling human dynamics of face-to-face interaction networks 

      Starnini, Michele; Baronchelli, Andrea; Pastor Satorras, Romualdo (American Institute of Physics (AIP), 2013-04-15)
      Article
      Open Access
      Face-to-face interaction networks describe social interactions in human gatherings, and are the substrate for processes such as epidemic spreading and gossip propagation. The bursty nature of human behavior characterizes ...
    • Ordering dynamics of the multi-state voter model 

      Starnini, Michele; Baronchelli, Andrea; Pastor Satorras, Romualdo (Institute of Physics (IOP), 2012-10-30)
      Article
      Open Access
      The voter model is a paradigm of ordering dynamics. At each time step, a random node is selected and copies the state of one of its neighbors. Traditionally, this state has been considered as a binary variable. Here, we ...
    • Quantifying echo chamber effects in information spreading over political communication networks 

      Cota, Wesley; Ferreira, Silvio C.; Pastor Satorras, Romualdo; Starnini, Michele (2019-12-09)
      Article
      Open Access
      Echo chambers in online social networks, in which users prefer to interact only with ideologically-aligned peers, are believed to facilitate misinformation spreading and contribute to radicalize political discourse. In ...
    • Random walks in non-Poissoinan activity driven temporal networks 

      Moinet, Antoine; Starnini, Michele; Pastor Satorras, Romualdo (2019-09-17)
      Article
      Open Access
      The interest in non-Markovian dynamics within the complex systems community has recently blossomed, due to a new wealth of time-resolved data pointing out the bursty dynamics of many natural and human interactions, manifested ...
    • Random walks on temporal networks 

      Starnini, Michele; Baronchelli, Andrea; Barrat, Alain; Pastor Satorras, Romualdo (2012)
      Article
      Open Access
      Many natural and artificial networks evolve in time. Nodes and connections appear and disappear at various time scales, and their dynamics has profound consequences for any processes in which they are involved. The first ...
    • Temporal percolation in activity-driven networks 

      Starnini, Michele; Pastor Satorras, Romualdo (2014-03-14)
      Article
      Open Access
      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 ...

      Doctoral thesis
      Open Access
      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 ...
