      Comunicació de congrés
      Accés obert
      We explore the identification of neuronal voltage traces by artificial neural networks based on wavelets (Wavenet). More precisely, we apply a modification in the representation of dynamical systems by Wavenet which decreases ...

    • A characterization of isochronous centres in terms of symmetries 

      Freire, Emilio; Gasull Embid, Armengol; Guillamon Grabolosa, Antoni (2000)
      Article
      Accés obert
      We present a description of isochronous centres of planar vector fields $X$ by means of their groups of symmetries. More precisely, given a normalizer $U$ of $X$ (i.e., $[X,U]=\mu X$, where $\mu$ is a scalar function), we ...

      aCTeX és una aplicació web que genera dinàmicament llistats de preguntes tipus test, amb la particularitat que admet expressions matemàtiques introduïdes en llenguatge LaTeX a la base de dades. L’aplicació executa la ...

    • Allosteric binding cooperativity in a kinetic context 

      Díaz Sanzo, Óscar; Martín, Víctor; Renault de Barros, Pedro Víctor; Romero Sánchez, David; Guillamon Grabolosa, Antoni; Giraldo Arjonilla, Jesús (2023-02)
      Article
      Accés obert
      Allosteric modulators are of prime interest in drug discovery. These drugs regulate the binding and function of endogenous ligands, with some advantages over orthosteric ligands. A typical pharmacological parameter in ...

    • An analytic-numerical method of computation of the Liapunov and period constants derived from their algebraic structure 

      Gasull Embid, Armengol; Guillamon Grabolosa, Antoni; Mañosa Fernández, Víctor (1996)
      Article
      Accés obert
      We consider the problem of computing the Liapunov and the period constants for a smooth differential equation with a non degenerate critical point. First, we investigate the structure of both constants when they are ...

    • An explicit expression of the first Liapunov and period constants with applications 

      Gasull Embid, Armengol; Guillamon Grabolosa, Antoni; Mañosa Fernández, Víctor (1996)
      Article
      Accés obert
      In this paper, we study systems in the plane having a critical point with pure imaginary eigenvalues, and we search for effective conditions to discern whether this critical point is a focus or a center; in the case of it ...

    • Àlgebra lineal i càlcul infinitesimal 

      Bruguera Padró, Maria Montserrat; Ferrer Biosca, Alberto; Guillamon Grabolosa, Antoni; Mitjana Riera, Margarida; Pañella Brustenga, Francisco de Asís; Puerta Coll, Xavier; Rodríguez Jordana, Juan; Serrat Piè, Carles; Torrent Torrent, Juan Antonio (Universitat Politècnica de Catalunya, 2003)

    • Bifurcation gaps in asymmetric and high-dimensional hypercycles 

      Puig, Júlia; Farre, Gerard; Guillamon Grabolosa, Antoni; Fontich Julia, Ernest; Sardanyes, Josep (2018-01-01)
      Article
      Accés obert
      Hypercycles are catalytic systems with cyclic architecture. These systems have been suggested to play a key role in the maintenance and increase of information in prebiotic replicators. It is known that for a large enough ...

    • Bifurcations analysis of oscillating hypercycles 

      Guillamon Grabolosa, Antoni; Fontich, Ernest; Sardañés, Josep (2015-12-21)
      Article
      Accés obert
      We investigate the dynamics and transitions to extinction of hypercycles governed by periodic orbits. For a large enough number of hypercycle species (n > 4) the existence of a stable periodic orbit has been previously ...

    • Bivalent chromatin as a therapeutic target in cancer: an in silico predictive approach for combining epigenetic drugs
