    • Assessing diversity in multiplex networks 

      Carpi, Laura C.; Schieber, Tiabo A.; Pardalos, Panos M.; Marfany Nadal, Gemma; Masoller Alonso, Cristina; Díaz Guilera, Albert; Ravetti, Martin G. (Nature, 2019-03-14)
      Article
      Open Access
      Diversity, understood as the variety of different elements or configurations that an extensive system has, is a crucial property that allows maintaining the system’s functionality in a changing environment, where failures, ...
    • Correlations in the organization of large-scale syntactic dependency networks 

      Ferrer Cancho, Ramon; Mehler, Alexander; Pustylnikov, Olga; Díaz Guilera, Albert (Association for Computational Linguistics, 2007)
      Conference report
      Open Access
      We study the correlations in the connectivity patterns of large scale syntactic dependency networks. These networks are induced from treebanks: their vertices denote word forms which occur as nuclei of dependency trees. ...
    • Disorder-induced temperature fluctuations in nonequilibrium systems 

      Díaz Guilera, Albert; Torner Sabata, Lluís; Rubí Capaceti, José Miguel (1992-01)
      Article
      Restricted access - publisher's policy
      The authors study the effects on heat diffusion related to the presence of a quenched disorder of impurities at the boundaries. A simple lattice model summarizes the main characteristics of the surface through which the ...
    • On fluctuations in interfacial fluid systems 

      Torner Sabata, Lluís; Rubí Capaceti, José Miguel; Díaz Guilera, Albert (1989-06)
      Article
      Restricted access - publisher's policy
      We study the propagation of the temperature fluctuations in a system in the presence of an interface. Such fluctuations originate from surface noise sources which are introduced through the random parts of the interfacial ...
    • Quantification of network structural dissimilarities 

      Schieber, Tiabo A.; Carpi, Laura; Díaz Guilera, Albert; Pardalos, Panos M.; Masoller Alonso, Cristina; Ravetti, Martin G. (2017-01-09)
      Article
      Open Access
      Identifying and quantifying dissimilarities among graphs is a fundamental and challenging problem of practical importance in many fields of science. Current methods of network comparison are limited to extract only partial ...
    • Spatial correlations for temperature fluctuations from surface noise 

      Rubí Capaceti, José Miguel; Díaz Guilera, Albert; Torner Sabata, Lluís (1987-02)
      Article
      Restricted access - publisher's policy
      The equal-time or static temperature correlation function from fluctuations originated at a surface is computed. Such fluctuations come from a random heat flux appearing in Newton's law of cooling. The correlation is studied ...
    • The global minima of the communicative energy of natural communication systems 

      Ferrer Cancho, Ramon; Díaz Guilera, Albert (Institute of Physics (IOP), 2007-06)
      Article
      Open Access
      Until recently, models of communication have explicitly or implicitly assumed that the goal of a communication system is just maximizing the information transfer between signals and `meanings'. Recently, it has been argued ...
