    Bitlloch, Pau; Ruiz Martí, Xavier; Ramírez de la Piscina Millán, Laureano; Casademunt Viader, Jaume (2018-06-23)
    Article
    Accés obert
    Lattice-Boltzmann simulations of a turbulent duct flow have been carried out to obtain trajectories of passive tracers in the conditions of a series of microgravity experiments of turbulent bubble suspensions. The statistics ...
  • Generation and control of monodisperse bubble suspensions in microgravity 

    Bitlloch, Pau; Ruiz Martí, Xavier; Ramírez de la Piscina Millán, Laureano; Casademunt Viader, Jaume (2018-06-01)
    Article
    Accés obert
    A new experimental setup for the generation of homogeneous, monodisperse bubble suspensions in turbulent duct flows in microgravity has been designed and tested in drop tower experiments. The setup provides independent ...
  • Periodic spiking by a pair of ionic channels 

    Ramírez de la Piscina Millán, Laureano; Sancho Herrero, José María (2018-09-01)
    Article
    Accés obert
    Neuronal cells present periodic trains of localized voltage spikes involving a large amount of different ionic channels. A relevant question is whether this is a cooperative effect or it could also be an intrinsic property ...
  • Fixed-density boundary conditions in overdamped Langevin simulations of diffusion in channels 

    Ramírez de la Piscina Millán, Laureano (2018-07)
    Article
    Accés obert
    We consider the numerical integration of Langevin equations for particles in a channel, in the presence of boundary conditions fixing the concentration values at the ends. This kind of boundary condition appears for instance ...
  • Using archaeomagnetism to improve the dating of three sites in Catalonia (NE Spain) 

    Casas, Lluís; Auguet Sangrá, Carlota E.; Cantoni, Gerard; López Vilar, Jordi; Guasch Ferré, Núria; Prevosti Monclús, Marta (2018)
    Article
    Accés obert
    Archaeomagnetic dating was performed on four archaeological structures in Catalonia (NE Spain) using magnetic inclination and declination values from three reference curves: the Iberian SVC and two curves computed using ...
  • Seedling emergence through soil surface seals under laboratory conditions: effect of mechanical impedance and seal moisture 

    Mas Serra, Maite; Verdú González, Antoni Maria Claret; Ginovart Gisbert, Marta; Josa March, Ramon (2017)
    Article
    Accés obert
    It is well known that soil sealing strongly affects seedling emergence. The effect of soil sealing on the emergence of flax and turnip seedlings was studied in the laboratory. Seeds were sown in pots, watered, then covered ...
  • How to deal with the modelling of epidemics? Some ideas and examples to be implemented in the classroom! 

    Ginovart Gisbert, Marta (2017)
    Article
    Accés restringit per política de l'editorial
    The general objective of this work is to deal with different approaches for the representation of an epidemic considering the state of the individuals in the population, Susceptible, Infected or Recovered (SIR), which ...
  • Ordering kinetics evaluation of FeAl powders 

    Cinca Luis, Nuria; Isalgue Buxeda, Antonio; Auguet Sangrá, Carlota E.; Concustell, Amadeu; Cano, I. G.; Guilemany Casademont, Josep Maria; Fauth, F. (2017-12-01)
    Article
    Accés obert
    In this study, time resolved X-ray diffraction experiments using synchrotron X-ray radiation have been performed to get insight on the time and temperature dependent atomic ordering of an intermetallic Fe-40Al (at.%) ...
  • Discretization-dependent model for weakly connected excitable media 

    Arroyo Silva, Pedro André; Alonso Muñoz, Sergio; Weber dos Santos, Rodrigo (American Chemical Society (ACS), 2018-03-23)
    Article
    Accés obert
    Pattern formation has been widely observed in extended chemical and biological processes. Although the biochemical systems are highly heterogeneous, homogenized continuum approaches formed by partial differential equations ...
  • CD5L promotes M2 macrophage polarization through autophagy-mediated upregulation of ID3 

    Sanjurjo, Lucía; Aran, Gemma; Téllez, Érica; Amézaga, Núria; Armengol, Carolina; Prats Soler, Clara; López Codina, Daniel; Sarrias, Maria Rosa (2018-03-12)
    Article
    Accés obert
    CD5L (CD5 molecule-like) is a secreted glycoprotein that controls key mechanisms in inflammatory responses, with involvement in processes such as infection, atherosclerosis, and cancer. In macrophages, CD5L promotes an ...
  • Improving dating of three sites from Catalonia (NE Spain) via Archaeomagnetism

  • Calcium alternans produced by increased sarcoplasmic reticulum refractoriness 

    Rodríguez Cantalapiedra, Inma; Lugo Vélez, Carlos Antonio; Peñaranda Ayllón, Angelina; Echebarría Domínguez, Blas (2011-09-29)
    Article
    Accés obert
    Despite the important role of electro-mechanical alternans in cardiac arrhythmogenesis, its molecular origin is not well understood. In this paper we want to study alternans that can be associated with alternations in the ...
