    • Front propagation in spatially modulated media 

      Armero, J.; Lacasta Palacio, Ana María; Ramírez de la Piscina Millán, Laureano; Casademunt, Jaume; Sancho, Jose Maria; Sagués Mestre, Francesc (American Physical Society, 1997-09-01)
      Article
      Accés obert
      A two-dimensional reaction-diffusion front which propagates in a modulated medium is studied. The modulation consists of a spatial variation of the local front velocity in the transverse direction to that of the ...

    • Mechanical oscillations in biological tissues as a result of delayed rest-length changes 

      Muñoz Romero, José; Dingle, Monica; Wenzel, Manuel (American Institute of Physics (AIP), 2018-11-26)
      Article
      Accés obert
      Oscillatory behavior in tissue biology is ubiquitous and may be observed in the form of either chemical or mechanical signals. We present here and solve a mechanical cell model that exhibits oscillations emerging from ...

    • Pattern and velocity selection of fronts propagating in modulated media 

      Armero, J.; Lacasta Palacio, Ana María; Ramírez de la Piscina Millán, Laureano; Casademunt, Jaume; Sancho, Jose Maria; Sagués Mestre, Francesc (EDP Sciences, 1996-02-01)
      Article
      Accés obert
      We study the problem of pattern and velocity selection of morphologically stable two-dimensional fronts propagating in a spatially modulated medium. The generic system is governed by a local equation and evolves towards a ...

    • Wave competition in excitable modulated media 

      Sendiña-Nadal, I.; Gómez Gesteira, Moncho; Pérez Muñuzuri, Vicente; Pérez Villar, Vicente; Armero, J.; Ramírez de la Piscina Millán, Laureano; Casademunt, Jaume; Sancho, Jose Maria; Sagués Mestre, Francesc (American Physical Society, 1997-12-31)
      Article
      Accés obert
      The propagation of an initially planar front is studied within the framework of the photosensitive Belousov- Zhabotinsky reaction modulated by a smooth spatial variation of the local front velocity in the direction perpendicular ...

    • Wave propagation in a medium with disordered excitability 

      Sendiña-Nadal, I.; Pérez Muñuzuri, Alberto; Vives, D.; Pérez Muñuzuri, Vicente; Casademunt, Jaume; Ramírez de la Piscina Millán, Laureano; Sancho, Jose Maria; Sagués Mestre, Francesc (American Physical Society, 1998-06-30)
      Article
      Accés obert
      The effect of quenched disorder on the propagation of autowaves in excitable media is studied both experimentally and numerically in relation to the light-sensitive Belousov-Zhabotinsky reaction. The spatial disorder is ...
