  • Huge reduction of defibrillation thresholds using four electrode defibrillators 

    Simic, Ana; Rodríguez Cantalapiedra, Inma; Elorza Barbajero, Jorge; Bragard, Jean (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Open Access
    In the absence of a better solution, ventricular fibrillation is treated by applying one or several large electrical shocks to the patient. The question of how to lower the energy required for a successful shock is still ...

  • Influence of gap junction dynamics on the stability of reentrant waves in cadiac tissue 

    Hawks, Claudia; Elorza Barbajero, Jorge; Echebarría Domínguez, Blas; Rodríguez Cantalapiedra, Inma; Peñaranda Ayllón, Angelina; Bragard, Jean (2015)
    Conference report
    Open Access
    Constant conductances are often assumed when model- ing cardiac tissue. However experimental evidences have shown that gap junctions (GJ) actually connect adjacent cardiac myocytes. These GJ are complex proteins of ...

  • On the Induction of New Fuzzy Relations, New Fuzzy Operators and Their Aggregation 

    Carmona Cervelló, Neus; Elorza, Jorge; Recasens Ferrés, Jorge; Bragard, Jean (Springer, 2013)
    Article
    Open Access
    In this paper we generate fuzzy relations and fuzzy operators using different kind of generators and we study the relationship between them. Firstly, we introduce a new fuzzy preorder induced by a fuzzy operator. We ...
  • Permutability of fuzzy consequence operators and fuzzy interior operators 

    Carmona, Neus; Elorza, Jorge; Recasens Ferrés, Jorge; Bragard, Jean (2013)
    Article
    Restricted access - publisher's policy
    In this paper we study the permutability of the composition of fuzzy consequence operators (fuzzy closings) and fuzzy interior operators (fuzzy openings). We establish several characterizations and we show the relation of ...
  • Permutable fuzzy consequence and interior operators and their connection with fuzzy relations 

    Carmona, Neus; Elorza Barbajero, Jorge; Recasens Ferrés, Jorge; Bragard, Jean (2015-07-20)
    Article
    Open Access
    Fuzzy operators are an essential tool in many fields and the operation of composition is often needed. In general, composition is not a commutative operation. However, it is very useful to have operators for which the order ...
  • Phase-2 reentry in cardiac tissue: role of the slow calcium pulse 

    Rodríguez Cantalapiedra, Inma; Peñaranda Ayllón, Angelina; Echebarría Domínguez, Blas; Bragard, Jean (2010-07-13)
    Article
    Open Access
    Phase-2 re-entry is thought to underlie many causes of idiopathic ventricular arrhythmias as, for instance, those occurring in Brugada syndrome. In this paper, we study under which circumstances a region of depolarized tissue ...
  • Some illustrative examples of permutability of fuzzy operators and fuzzy relations 

    Carmona, Neus; Elorza, Jorge; Recasens Ferrés, Jorge; Bragard, Jean (2014)
    Conference report
    Open Access
    Composition of fuzzy operators often appears and it is natural to ask when the order of composition does not change the result. In previous papers, we characterized permutability in the case of fuzzy consequence operators ...
