    • Empirical modeling and prediction of neuronal dynamics 

      Fisco Compte, Pau; Aquilué Llorens, David; Roqueiro, Nestor; Fossas Colet, Enric; Guillamon Grabolosa, Antoni (Springer, 2024-04-10)
      Article
      Accés obert
      Mathematical modeling of neuronal dynamics has experienced a fast growth in the last decades thanks to the biophysical formalism introduced by Hodgkin and Huxley in the 1950s. Other types of models (for instance, integrate ...

    • An equivariant Reeb–Beltrami correspondence and the Kepler–Euler flow 

      Fontana McNally, Josep; Miranda Galcerán, Eva; Peralta Salas, Daniel (Royal Society, 2024-01-31)
      Article
      Accés obert
      We prove that the correspondence between Reeb and Beltrami vector fields presented in Etnyre & Ghrist (Etnyre, Ghrist 2000 Nonlinearity 13, 441–458 (doi:10.1088/0951-7715/13/2/306)) can be made equivariant whenever additional ...

    • Almost Moore and the largest mixed graphs of diameters two and three 

      Dalfó Simó, Cristina; Fiol Mora, Miquel Àngel; López Lorenzo, Nacho (Elsevier, 2024-01-01)
      Article
      Accés obert
      Almost Moore mixed graphs appear in the context of the degree/diameter problem as a class of extremal mixed graphs, in the sense that their order is one unit less than the Moore bound for such graphs. The problem of their ...

    • Optimal dispersal and diffusion-enhanced robustness in two-patch metapopulations: origin’s saddle-source nature matters 

      Jorba Cuscó, Marc; Oliva Zúniga, Ruth Idalia; Sardanyes Cayuela, Josep; Pérez Palau, Daniel (Springer, 2024-02-21)
      Article
      Accés obert
      A two-patch logistic metapopulation model is investigated both analytically and numerically focusing on the impact of dispersal on population dynamics. First, the dependence of the global dynamics on the stability type of ...

    • On a radical extension of the field of rational functions in several variables 

      Vela del Olmo, Maria Montserrat (American Mathematical Society (AMS), 2023-09)
      Article
      Accés obert
      Review of On a radical extension of the field of rational functions in several variables, Xiang-dong Hou and Christopher Sze, Linear and multilinear algebra, 71 (6), (2023), 1015-1025

    • Problèmes de plongement finis sur les corps non commutatifs 

      Vela del Olmo, Maria Montserrat (American Mathematical Society (AMS), 2023)
      Article
      Accés obert
      Review of Problèmes de plongement finis sur les corps non commutatifs, A. Behajaina, B.Deschamps and F. Legrand, Israel Journal of Mathematics, 249, (2022), 617-650.

    • Assessment of noise of MEMS IMU sensors of different grades for GNSS/IMU navigation 

      Suvorkin, Vladimir; García Fernández, Miquel; González Casado, Guillermo; Li, Mowen; Rovira Garcia, Adrià (Multidisciplinary Digital Publishing Institute (MDPI), 2024-03-19)
      Article
      Accés obert
      Inertial measurement units (IMUs) are key components of various applications including navigation, robotics, aerospace, and automotive systems. IMU sensor characteristics have a significant impact on the accuracy and ...

    • Graphs with isolation number equal to one third of the order 

      Lemanska, Magdalena; Mora Giné, Mercè; Souto Salorio, María josé (Elsevier, 2024-05-01)
      Article
      Accés restringit per política de l'editorial
      A set D of vertices of a graph G is isolating if the set of vertices not in D and with no neighbor in D is independent. The isolation number of G, denoted by , is the minimum cardinality of an isolating set of G. It is ...

    • Approximation in the Zygmund and Hölder classes on Rn 

      Saksman, Eero; Soler i Gibert, Odí (Canadian Mathematical Society, 2022-12)
      Article
      Accés obert
      We determine the distance (up to a multiplicative constant) in the Zygmund class ¿*(Rn) to the subspace J(bmo)(Rn). The latter space is the image under the Bessel potential J:=(1-¿)-1/2 of the space bmo(Rn) , which is a ...

    • Proper colouring Painter–Builder game
