    • Navigability of temporal networks in hyperbolic space 

      ortiz, elisenda; Starnini, Michele; Serrano, M. Angels (Nature, 2017-11-08)
      Article
      Accés obert
      Information routing is one of the main tasks in many complex networks with a communication function. Maps produced by embedding the networks in hyperbolic space can assist this task enabling the implementation of efficient ...
    • No echo in the chambers of political interactions on Reddit 

      De Francisci Morales, Gianmarco; Monti, Corrado; Starnini, Michele (Nature, 2021-02-02)
      Article
      Accés obert
      Echo chambers in online social networks, whereby users’ beliefs are reinforced by interactions with like-minded peers and insulation from others’ points of view, have been decried as a cause of political polarization. Here, ...
    • Online conspiracy communities are more resilient to deplatforming 

      Monti, Corrado; Cinelli, Matteo; Valensise, Carlo; Quattrociocchi, Walter; Starnini, Michele (2023-10-01)
      Article
      Accés obert
      Online social media foster the creation of active communities around shared narratives. Such communities may turn into incubators for conspiracy theories—some spreading violent messages that could sharpen the debate and ...
    • Ordering dynamics of the multi-state voter model 

      Starnini, Michele; Baronchelli, Andrea; Pastor Satorras, Romualdo (Institute of Physics (IOP), 2012-10-30)
      Article
      Accés obert
      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 ...
    • Political context of the European vaccine debate on Twitter 

      Paoletti, Giordano; Dall'Amico, Lorenzo; Kalimeri, Kyriaki; Lenti, Jacopo; Mejova, Yelena; Paolotti, Daniela; Starnini, Michele; Tizzani, Michele (Springer, 2024-12-01)
      Article
      Accés obert
      At the beginning of the COVID-19 pandemic, fears grew that making vaccination a political (instead of public health) issue may impact the efficacy of this life-saving intervention, spurring the spread of vaccine-hesitant ...
    • Prediction of new scientific collaborations through multiplex networks 

      Tuninetti, Marta; Aleta, Alberto; Paolotti, Daniela; Moreno, Yamir; Starnini, Michele (2021-12)
      Article
      Accés obert
      The establishment of new collaborations among scientists fertilizes the scientific environment, fostering novel discoveries. Understanding the dynamics driving the development of scientific collaborations is thus crucial ...
    • 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
      Accés obert
      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
      Accés obert
      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
      Accés obert
      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
      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 ...
    • The echo chamber effect on social media 

      Cinelli, Matteo; De Francisci Morales, Gianmarco; Galeazzi, Alessandro; Quattrociocchi, Walter; Starnini, Michele (2021-02-23)
      Article
      Accés obert
      Social media may limit the exposure to diverse perspectives and favor the formation of groups of like-minded users framing and reinforcing a shared narrative, that is, echo chambers. However, the interaction paradigms among ...
    • The interconnected wealth of nations: shock propagation on global trade-investment multiplex networks 

      Starnini, Michele; Boguña Espinal, Marian; Serrano, M.Angels (Nature, 2019-09-11)
      Article
      Accés obert
      The increasing integration of world economies, which organize in complex multilayer networks of interactions, is one of the critical factors for the global propagation of economic crises. We adopt the network science ...
