    • Limit-cycle oscillations and stable patterns in repressor lattices 

      Chakraborty, Sudipta; Jensen, M.H.; Krishna, Sandeep; Mengel Pers, B.; Pigolotti, Simone; Sekara, V.; Semsey, S. (2012-09-07)
      Article
      Accés obert
      As a model for cell-to-cell communication in biological tissues, we construct repressor lattices by repeating a regulatory three-node motif on a hexagonal structure. Local interactions can be unidirectional, where a node ...
    • Numerical and experimental study of the effects of noise on the permutation entropy 

      Quintero Quiroz, Carlos Alberto; Pigolotti, Simone; Torrent Serra, Maria del Carmen; Masoller Alonso, Cristina (2015-09-02)
      Article
      Accés obert
      We analyze the effects of noise on the permutation entropy of dynamical systems. We take as numerical examples the logistic map and the Rössler system. Upon varying the noise strength we find a transition from an ...
    • Particle algorithms for population dynamics in flows 

      Perlekar, P.; Benzi, R.; Pigolotti, Simone; Toschi, F. (2011)
      Article
      Accés obert
      We present and discuss particle based algorithms to numerically study the dynamics of population subjected to an advecting flow condition. We discuss few possible variants of the algorithms and compare them in a model ...
    • Protocols for copying and proofreading in template-assisted polymerization 

      Pigolotti, Simone; Sartori, Pablo (2016-03)
      Article
      Accés obert
      We discuss how information encoded in a template polymer can be stochastically copied into a copy polymer. We consider four different stochastic copy protocols of increasing complexity, inspired by building blocks of the ...
    • Selective advantage of diffusing faster 

      Pigolotti, Simone; Benzi, R. (2014-05-09)
      Article
      Accés obert
      We study a stochastic spatial model of biological competition in which two species have the same birth and death rates, but different diffusion constants. In the absence of this difference, the model can be considered as ...
    • Stochastic competition between two populations in space 

      Pigolotti, Simone; Benzi, Roberto; Jensen, Mogens H.; Perlekar, Prasad; Toschi, Federico (2014-06-10)
      Capítol de llibre
      Accés restringit per política de l'editorial
    • Stochastic model for the species abundance problem 

      Pigolotti, Simone; Flammini, Alessandro; Maritan, Amos (2004-05-30)
      Article
      Accés obert
      We propose a model based on coupled multiplicative stochastic processes to understand the dynamics of competing species in an ecosystem. This process can be conveniently described by a Fokker-Planck equation. We provide ...
    • Stochasticity enhances the gaining of bet-hedging strategies in contact-process-like dynamics 

      Hidalgo, Juan J.; Pigolotti, Simone; Muñoz Martínez, Miguel Ángel (2015-03-10)
      Article
      Accés obert
    • Thermodynamics of error correction 

      Sartori, Pablo; Pigolotti, Simone (2015-12-10)
      Article
      Accés obert
      Information processing at the molecular scale is limited by thermal fluctuations. This can cause undesired consequences in copying information since thermal noise can lead to errors that can compromise the functionality ...
    • What ecological factors shape species-area curves in neutral models? 

      Cencini, Massimo; Pigolotti, Simone; Muñoz Messineo, Miguel Ángel (2012-06-04)
      Article
      Accés obert
      Understanding factors that shape biodiversity and species coexistence across scales is of utmost importance in ecology, both theoretically and for conservation policies. Species-area relationships (SARs), measuring how the ...
