    • Amplitude death and restoration in networks of oscillators with random-walk diffusion 

      Clusella Coberó, Pau; Pastor Satorras, Romualdo (2021-01-26)
      Article
      Accés obert
      Systems composed of reactive particles diffusing in a network display emergent dynamics. While Fick’s diffusion can lead to Turing patterns, other diffusion schemes might display more complex phenomena. Here we study the ...

    • Collective versus hub activation of epidemic phases on networks 

      Ferreira, Silvio C.; Salvador, Renan; Pastor Satorras, Romualdo (AMER PHYSICAL SOC, 2016-03-14)
      Article
      Accés restringit per política de l'editorial
      We consider a general criterion to discern the nature of the threshold in epidemic models on scale-free (SF) networks. Comparing the epidemic lifespan of the nodes with largest degrees with the infection time between them, ...

    • Core and critical cities of global region airport networks 

      Lordan González, Oriol; Sallán Leyes, José María (2019-01-01)
      Article
      Accés obert
      Air transport is one of the key infrastructures of today’s global economy. Connections between airports define airport networks, where nodes are cities served by airports, connected by edges if there is at least one direct ...

    • Effects of local population structure in a reaction-diffusion model of a contact process on metapopulation networks 

      de Souza Mata, Angelica; Ferreira, Silvio C.; Pastor Satorras, Romualdo (2013-10-30)
      Article
      Accés obert
      We investigate the effects of local population structure in reaction-diffusion processes representing a contact process (CP) on metapopulations represented as complex networks. Considering a model in which the nodes of a ...

    • Epidemic processes in complex networks 

      Pastor Satorras, Romualdo; Castellano, Claudio; Van Mieghem, Piet; Vespignani, Alessandro (2015-08-31)
      Article
      Accés obert
      In recent years the research community has accumulated overwhelming evidence for the emergence of complex and heterogeneous connectivity patterns in a wide range of biological and sociotechnical systems. The complex ...

    • Heuristics of node selection criteria to assess robustness of world airport network 

      Soria Guerrero, Manel; Lordan González, Oriol; Sallán Leyes, José María (2017-06-14)
      Article
      Accés obert
      The world airport network (WAN) is one of the networked infrastructures that shape today's economic and social activity, so its resilience against incidents affecting the WAN is an important problem. In this paper, the ...

    • Impact of lag information on network inference 

      Rubido, Nicolás; Masoller Alonso, Cristina (Springer, 2018-11-01)
      Article
      Accés obert
      Extracting useful information from data is a fundamental challenge across disciplines as diverse as climate, neuroscience, genetics, and ecology. In the era of “big data,” data is ubiquitous, but appropriate methods are ...

    • Inferring the connectivity of coupled oscillators from time-series statistical similarity analysis 

      Tirabassi, Giulio; Sevilla Escoboza, Ricardo; Martín Buldú, Javier; Masoller Alonso, Cristina (Macmillan Publishers, 2015-06-04)
      Article
      Accés obert
      A system composed by interacting dynamical elements can be represented by a network, where the nodes represent the elements that constitute the system, and the links account for their interactions, which arise due to a ...

    • Non-mean-field behavior of the contact process on scale-free networks 

      Castellano, Claudio; Pastor Satorras, Romualdo (2006)
      Article
      Accés obert
      We present an analysis of the classical contact process on scale-free networks. A mean-field study, both for finite and infinite network sizes, yields an absorbing-state phase transition at a finite critical value of the ...
