    • Propagation malfunctions due to gap junction dysregulation 

      Rodríguez Cantalapiedra, Inma; Peñaranda Ayllón, Angelina; Echebarría Domínguez, Blas (2014)
      Conference lecture
      Open Access
      Gap junctions are membrane channels that connect the cytoplasm of adjacent cells allowing the cell-to-cell electrical coupling necessary for action potential propagation. Pathological conditions, such as malformations in ...

    • Multilevel analysis of calcium dynamics in stimulated cultures of cardiomyocytes 

      Vallmitjana Lees, Alexander; Hove-Madsen, Leif; Barriga, Montserrat; Benítez Iglesias, Raúl (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Conference report
      Restricted access - publisher's policy
      We present an automatic method to characterize calcium activity in a culture of cardiac cells from a sequence of microscopy fluorescence images. The approach quantifies both the response of each individual cell in the ...

    • Study of a system to generate electricity on the Moon's surface during the lunar night 

      Torroba, Oscar; Climent, Blai; González Cinca, Ricardo; Ramachandran, Narayanan; Griffin, Michael D. (2012)
      Conference report
      Restricted access - author's decision
      One of the biggest challenges of the exploration of the Moon is the survival of the crew and the lunar assets during the lunar night. The environmental conditions on the lunar surface and its cycle, with long periods of ...

    • Bubble and slug flows characteristic lengths in a microchannel 

      Arias Calderón, Santiago; González Cinca, Ricardo (2012)
      Conference report
      Open Access

    • Nonlinearities due to refractoriness in SR Ca release 

      Peñaranda Ayllón, Angelina; Álvarez Lacalle, Enrique; Rodríguez Cantalapiedra, Inma; Hove-Madsen, Leif; Echebarría Domínguez, Blas (2012)
      Conference lecture
      Open Access
      Calcium alternans is a pro-arrhytmic cardiac dysfunction related to beat-to-beat changes in the amplitude of intracellular calcium transient, that typically occurs at rapid pacing rates. Although oscillations in sarcoplasmic ...

    • Slow pulse due to calcium current induces phase-2 reentry in heterogeneous tissue 

      Peñaranda Ayllón, Angelina; Rodríguez Cantalapiedra, Inma; Echebarría Domínguez, Blas (2010)
      Conference report
      Restricted access - publisher's policy
      Phase-2 reentry is a basic mechanism for the transition to VT and VF in the heart. It is thought to underly many causes of idiopathic ventricular arrhythmias as, for instance, those occurring in Brugada syndrome. ...

    • Calcium alternans produced by increased sarcoplasmic reticulum refractoriness 

      Rodríguez Cantalapiedra, Inma; Lugo, Carlos; Peñaranda Ayllón, Angelina; Echebarría Domínguez, Blas (IEEE Computer Society Publications, 2011)
      Conference report
      Restricted access - publisher's policy
      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 ...

    • Comparison of two methods for generating small bubbles with a T-junction in microgravity conditions 

      Arias Calderón, Santiago; González Cinca, Ricardo (2011)
      Conference report
      Open Access

    • Numerical simulation of bubble generation in a T-junction 

      Arias Calderón, Santiago; Legendre, Dominique; González Cinca, Ricardo (2011)
      Conference report
      Open Access

    • Experimental setup for the study of jet interactions 

      Suñol Galofre, Francesc Xavier; Pino González, David; Maldonado, Oscar; González Cinca, Ricardo (2007)
      Conference lecture
      Open Access
      We present a new experimental setup for the study of bubble coalescence and bubble jet interactions in microgravity conditions [1].Test section consists of a cavity full of liquid containing two bubble injectors whose ...

    • Experimental analysis of bubble jets collision 

      Suñol Galofre, Francesc Xavier; González Cinca, Ricardo (2008)
      Conference report

    • Experimental setup for the study of the effects of vibrations on multiphase systems in suborbital flights 

      Arias Calderón, Santiago; Suñol Galofre, Francesc Xavier; González Cinca, Ricardo (2011)
      Conference report
      Open Access
      We present an experimental setup for the study of the effects of controlled harmonic vibrations applied on multiphase systems in microgravity. This setup was recently launched onboard an ESA/DLR/SNSB Mini-Texus rocket with ...
