  • Collective stochastic coherence and synchronizability in weighted scale-free networks 

    Balenzuela, Pablo; Rue Queralt, Pau; Boccaletti, Stefano; García Ojalvo, Jordi (2014-01-21)
    Article
    Open Access
    Coupling frequently enhances noise-induced coherence and synchronization in interacting nonlinear systems, but it does so separately. In principle collective stochastic coherence and synchronizability are incompatible ...
  • Information routing driven by background chatter in a signaling network 

    Domedel Puig, Núria; Rue Queralt, Pau; Pons Rivero, Antonio Javier; García Ojalvo, Jordi (2011-12-08)
    Article
    Open Access
    Living systems are capable of processing multiple sources of information simultaneously. This is true even at the cellular level, where not only coexisting signals stimulate the cell, but also the presence of fluctuating ...
  • Optimizing periodicity and polymodality in noise-induced genetic oscillators 

    Rue Queralt, Pau; Süel, Gürol M.; García Ojalvo, Jordi (2011)
    Article
    Open Access
    Many cellular functions are based on the rhythmic organization of biological processes into self-repeating cascades of events. Some of these periodic processes, such as the cell cycles of several species, exhibit conspicuous ...
  • Relaxation dynamics and frequency response of a noisy cell signaling network 

    Rue Queralt, Pau; Pons Rivero, Antonio Javier; Domedel Puig, Núria; García Ojalvo, Jordi (2010-12-30)
    Article
    Open Access
    We investigate the dynamics of cell signaling using an experimentally based Boolean model of the human fibroblast signal transduction network. We determine via systematic numerical simulations the relaxation dynamics of ...
  • Simulation methods with extended stability for stiff biochemical Kinetics 

    Rue Queralt, Pau; Villà-Freixa, Jordi; Burrage, Kevin (2010-08-11)
    Article
    Open Access
    Background: With increasing computer power, simulating the dynamics of complex systems in chemistry and biology is becoming increasingly routine. The modelling of individual reactions in (bio)chemical systems involves a ...
  • The histone variant macroH2A is an epigenetic regulator of key developmental genes 

    Buschbeck, Markus; Uribesalgo, Iris; Wibowo, Indra; Rue Queralt, Pau; Martín, David; Gutiérrez, Arantxa; Morey, Lluís; Guigó, Roderic; López-Schier; Di Croce, Luciano (2009-09-06)
    Article
    Restricted access - publisher's policy
    The histone variants macroH2A1 1 and macroH2A2 are associated with X chromosome inactivation in female mammals. However, the physiological function of macroH2A proteins on autosomes is poorly understood. Microarray-based ...
