  • Adaptation of saccharomyces to high glucose concentrations and its impact on growth kinetics of alcoholic fermentations 

    Ginovart Gisbert, Marta; Carbó Moliner, Rosa; Portell Canal, Xavier (Multidisciplinary Digital Publishing Institute (MDPI), 2024-07-17)
    Article
    Open Access
    Prior adaptation of Saccharomyces cerevisiae to the fermentation medium ensures its implantation and success in alcoholic fermentations. Fermentation kinetics can be characterized with mathematical models to objectively ...

  • Wind turbine gearbox early fault detection using Mel-frequency cepstral coefficients of vibration data 

    Velandia Cardenas, Cristian; Vidal Seguí, Yolanda; Pozo Montero, Francesc (2024-06-06)
    Article
    Open Access
    A methodology utilizing vibration data and Mel-frequency cepstral coefficients (MFCCs) for wind turbine condition monitoring is developed to detect incipient faults in the wind turbine gearbox. This approach provides a ...

  • Quasineutral multistability in an epidemiological-like model for defective-helper betacoronavirus infection in cell cultures 

    Muñoz Sánchez, Juan Carlos; Lázaro Ochoa, José Tomás; Hillung, Julia; Olmo Uceda, Maria-José; Sardanyes, Josep; Elena, Santiago (2025-01)
    Article
    Open Access
    It is well known that, during replication, RNA viruses spontaneously generate defective viral genomes (DVGs). DVGs are unable to complete an infectious cycle autonomously and depend on coinfection with a wild-type helper ...

  • A general method to find the spectrum and eigenspaces of the k-token graph of a cycle, and 2-token through continuous fractions 

    Reyes Quiróz, Mónica Andrea; Dalfó Simó, Cristina; Messegué Buisan, Arnau; Fiol Mora, Miquel Àngel (Elsevier, 2025-01)
    Article
    Open Access
    The k-token graph Fk(G) of a graph G is the graph whose vertices are the k-subsets of vertices from G, two of which being adjacent whenever their symmetric difference is a pair of adjacent vertices in G. In this paper, we ...

  • Token graphs of Cayley graphs as lifts 

    Dalfó Simó, Cristina; Fiol Mora, Miquel Àngel; Pavlíková, Sona; Siran, Josef (2024-05-31)
    Article
    Restricted access - publisher's policy
    This paper describes a general method for representing k -token graphs of Cayley graphs as lifts of voltage graphs. This allows us to construct line graphs of circulant graphs and Johnson graphs as lift graphs on cyclic ...

  • On the algebraic connectivity of some token graphs 

    Dalfó Simó, Cristina; Fiol Mora, Miquel Àngel (Springer, 2024-05-07)
    Article
    Open Access
    The k-token graph of a graph G is the graph whose vertices are the k-subsets of vertices from G, two of which are adjacent whenever their symmetric difference is a pair of adjacent vertices in G. It was proved that the ...

  • Topological entropy of Turing complete dynamics 

    Bruera Méndez, Renzo; Cardona Aguilar, Robert; Miranda Galcerán, Eva; Peralta-Salas, Daniel (2024-04-10)
    Research report
    Open Access
    We explore the relationship between Turing completeness and topological entropy of dynamical systems. We first prove that a natural class of Turing machines that we call “regular Turing machines” (which includes most of ...

  • On the collision dynamics in a molecular model 

    Barrabés Vera, Esther; Ollé Torner, Mercè; Rodríguez del Río, Óscar (Elsevier, 2024-04)
    Article
    Open Access
    We study the problem of the hydrogen atom submitted to a circularly polarized microwave field. This problem, analyzed from a classical mechanics approach, can be modeled by an autonomous Hamiltonian depending on one parameter ...

  • Equilibrium measures for Laplacian matrices in Random Walks 

    Carmona Mejías, Ángeles; Encinas Bachiller, Andrés Marcos; Jiménez Jiménez, María José; Martin Llopis, Álvar (2024)
    Conference report
    Open Access

  • Simulation of mechanical weathering for modeling rocky terrains 

    Mateos Arlanzón, Diego; Carranza Cobeñas, Luis Alberto; Susín Sánchez, Antonio; Argudo Medrano, Óscar (European Association for Computer Graphics (Eurographics), 2024)
    Conference report
    Open Access
    Synthetic terrains play a vital role in various applications, including entertainment, training, and simulation. This work focuses on rocky terrains akin to those found in alpine environments, which contain many complex ...

  • Application of the transfer matrix approximation for wave propagation in a metafluid representing an acoustic black hole duct termination 

    Guasch Fortuny, Oriol; Sánchez Martín, Patricia; Ghilardi, Davide (2020-01)
    Article
    Open Access
    The transfer matrix method has been proposed to analyze the acoustic black hole effect in duct terminations. The latter is achieved by placing a retarding waveguide structure inside the duct, which consists in a set of ...
