    • Mean-field diffusive dynamics on weighted networks 

      Baronchelli, Andrea; Pastor Satorras, Romualdo (2010-07-12)
      Article
      Accés obert
      Diffusion is a key element of a large set of phenomena occurring on natural and social systems modeled in terms of complex weighted networks. Here, we introduce a general formalism that allows to easily write down mean-field ...
    • Model reproduces individual, group and collective dynamics of human contact networks 

      Starnini, Michele; Baronchelli, Andrea; Pastor Satorras, Romualdo (2016-10-01)
      Article
      Accés obert
      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
      Accés obert
      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 ...
    • Networks in cognitive science 

      Baronchelli, Andrea; Ferrer Cancho, Ramon; Pastor Satorras, Romualdo; Chatter, Nick; Christiansen, Morten H. (Elsevier, 2013-07-01)
      Article
      Accés obert
      Networks of interconnected nodes have long played a key role in Cognitive Science, from artificial neural networks to spreading activation models of semantic memory. Recently, however, a new Network Science has been ...
    • 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 ...
    • Random walks and search in time-varying networks 

      Perra, N.; Baronchelli, Andrea; Mocanu, D.; Gonçalves, B.; Pastor Satorras, Romualdo; Vespignani, Alessandro (2012-12-04)
      Article
      Accés obert
      The random walk process underlies the description of a large number of real-world phenomena. Here we provide the study of random walk processes in time-varying networks in the regime of time-scale mixing, i.e., when the ...
    • Random walks on complex trees 

      Baronchelli, Andrea; Catanzaro, Michele; Pastor Satorras, Romualdo (2008-07-18)
      Article
      Accés obert
      We study the properties of random walks on complex trees. We observe that the absence of loops is reflected in physical observables showing large differences with respect to their looped counterparts. First, both the vertex ...
    • 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 ...
    • Role of feedback and broadcasting in the naming game 

      Baronchelli, Andrea (2011)
      Article
      Accés obert
      The naming game (NG) describes the agreement dynamics of a population of agents that interact locally in a pairwise fashion, and in recent years statistical physics tools and techniques have greatly contributed to shed ...
    • Scale-free networks emerging from multifractal time series 

      Budroni, Marcello A.; Baronchelli, Andrea; Pastor Satorras, Romualdo (American Chemical Society (ACS), 2017-05-16)
      Article
      Accés obert
      Methods connecting dynamical systems and graph theory have attracted increasing interest in the past few years, with applications ranging from a detailed comparison of different kinds of dynamics to the characterization ...
    • The biological origin of linguistic diversity 

      Baronchelli, Andrea; Chater, N.; Pastor Satorras, Romualdo; Christiansen, M.H. (2012-10-30)
      Article
      Accés obert
      In contrast with animal communication systems, diversity is characteristic of almost every aspect of human language. Languages variously employ tones, clicks, or manual signs to signal differences in meaning; some languages ...
    • Voter models on weighted networks 

      Baronchelli, Andrea; Castellano, Claudio; Pastor Satorras, Romualdo (2011-06-29)
      Article
      Accés obert
      We study the dynamics of the voter and Moran processes running on top of complex network substrates where each edge has a weight depending on the degree of the nodes it connects. For each elementary dynamical step the first ...
