  • Aging in language dynamics 

    Mukherjee, Animesh; Tria, Francesca; Baronchelli, Andrea; Puglisic, Andrea; Loreto, Vittorio (2011-02-17)
    Article
    Open Access
    Human languages evolve continuously, and a puzzling problem is how to reconcile the apparent robustness of most of the deep linguistic structures we use with the evidence that they undergo possibly slow, yet ceaseless, ...
  • Effects of mobility on ordering dynamics 

    Baronchelli, Andrea; Pastor Satorras, Romualdo (2009-11)
    Article
    Restricted access - publisher's policy
    Models of ordering dynamics allow us to understand natural systems in which an initially disordered population homogenizes some traits via local interactions. The simplest of these models, with wide applications ranging ...
  • Evolution in a changing environment 

    Baronchelli, Andrea; Chater, Nick; Christiansen, M.H.; Pastor Satorras, Romualdo (2013-01-10)
    Article
    Open Access
    We propose a simple model for genetic adaptation to a changing environment, describing a fitness landscape characterized by two maxima. One is associated with “specialist” individuals that are adapted to the environment; ...
  • 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
    Open Access
    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 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 ...
  • Role of feedback and broadcasting in the naming game 

    Baronchelli, Andrea (2011)
    Article
    Open Access
    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 ...
  • The biological origin of linguistic diversity 

    Baronchelli, Andrea; Chater, N.; Pastor Satorras, Romualdo; Christiansen, M.H. (2012-10-30)
    Article
    Open Access
    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 ...
