    • Small-scale structure of the disc velocity distribution. A maximum entropy statistical approach - Part II 

      Cubarsí Morera, Rafael (2009-12)
      Report de recerca
      Accés obert
      Among metallicity, colour, and other star properties, the eccentricity of the star’s orbit behaves as a very good sampling parameter to find a more detailed structure for the disc velocity distribution, allowing distinctions ...
    • Structure of the velocity distribution of the Galactic disc: a maximum entropy statistical approach - Part I 

      Cubarsí Morera, Rafael (2009-09)
      Report de recerca
      Accés obert
      The maximum entropy approach is proposed to describe the local structures of the veloc- ity distribution, which are collected through its sample moments. The method is used with several samples from the HIPPARCOS and ...
    • Study of the self organizing map of one local stellar sample 

      Hernández Pajares, Manuel; Cubarsí Morera, Rafael; Monte Moreno, Enrique (F. MURTAGH AND A. HECK, 1992)
      Text en actes de congrés

    • Switching cell penetrating and CXCR4-binding activities of nanoscale-organized arginine-rich peptides 

      Teixeira De Pinho Favaro, Marianna; Serna, Naroa; Sanchez Garcia, Laura; Cubarsí Morera, Rafael; Roldan, Monica; Sanchez Chardi, Alejandro; Unzueta, Ugutz; Mangues, Ramón; Ferrer Miralles, Neus; Rodrigues Azzoni, Adriano; Vazquez Gómez, Esther; Villaverde, Antonio (2018-08-01)
      Article
      Accés obert
      Arginine-rich protein motifs have been described as potent cell-penetrating peptides (CPPs) but also as rather specific ligands of the cell surface chemokine receptor CXCR4, involved in the infection by the human ...
    • Teorema astronómico de resistencia y unicidad 

      Cubarsí Morera, Rafael; Hernández Pajares, Manuel (Escola Tècnica Superior d'Enginyers de Telecomunicació de Barcelona, 1993)
      Article

    • The complete form of moment equations of stellar dynamics 

      Cubarsí Morera, Rafael (2007-03-30)
      Report de recerca
      Accés obert
      The exact mathematical expression for an arbitrary nth-order stellar hydrodynamic equation is explicitly obtained depending on the central moments of the velocity distribution. In such a form the equations are physically ...
    • The epicycle model 

      Cubarsí Morera, Rafael (2013-06)
      Article
      Accés obert
      Las soluciones de las ecuaciones del movimiento para una part cula de masa puntual bajo un campo de fuerzas conservativo estan generalmente ligadas a un conjunto b asico de integrales del movimiento, que dependen del ...
    • The self organizing map of neighbour stars and its kinematical interpretation 

      Hernández Pajares, Manuel; Cubarsí Morera, Rafael; Monte Moreno, Enrique (1993-02)
      Article
      Accés obert
      The Self-Organizing Map (SOM) is a neural network algorithm that has the special property ofcreating spatially organized tepresetüatioes of various features of input signals. The resulting maps resemble realneural structures ...
    • The shape of a galaxy is not much influenced by the potential as it might seem 

      Cubarsí Morera, Rafael (2013)
      Comunicació de congrés
      Accés obert
      The dynamics of a galaxy as a stellar system in statistical equilibrium is usually obtained from the superposition principle, based on the linearity of the Boltzmann collisionless equation (BCE) in regard to the phase space ...
    • Three kinematical methods to identify local galactic structures 

      Cubarsí Morera, Rafael; Alcobé López, Santiago; Vidojevic, S.; Ninkovic, S. (2010-05)
      Comunicació de congrés
      Accés obert
      Method one: by combining a sampling parameter related to an isolating integral of the stellar motion, an optimisation of the mixture approach, and a maximisation of the partition entropy for the constituent populations ...
    • Un desajuste en biotecnologia 

      Cubarsí Morera, Rafael; Vázquez, Esther; Villaverde, Antonio (2011-09)
      Article
      Accés obert
      Se modeliza la penetración de una versión modificada de la proteína verde fluorescente llamada GFP en el citoplasma y el núcleo de una célula de mamífero. El modelo matemático proporciona una primera aproximación ...
