  • Mapping life expectancy loss in Barcelona in 2020 

    Puig Oriol, Xavier; Ginebra Molins, Josep (2023-05-04)
    Article
    Open Access
    We use a Bayesian spatio-temporal model, first to smooth small-area initial life expectancy estimates inBarcelona for 2020, and second to predict what small-area life expectancy would have been in 2020 inabsence of covid-19 ...

  • Axisymmetric smoothed particle magnetohydrodynamics 

    García Senz, Domingo; Wissing, Robert; Cabezón Gómez, Rubén Martín; Vurgun, Eda; Linares Herreros, María Paz (Oxford University Press, 2023-01-01)
    Article
    Open Access
    Many astrophysical and terrestrial scenarios involving magnetic fields can be approached in axial geometry. Although the smoothed particle hydrodynamics (SPH) technique has been successfully extended to magneto-hydrodynamics ...

  • Variable selection for meaningful clustering of multitopic territorial data 

    Angerri Torredeflot, Xavier; Gibert, Karina (Multidisciplinary Digital Publishing Institute (MDPI), 2023-06-26)
    Article
    Open Access
    This paper proposes a new methodology to improve territorial cohesion in clustering processes where many variables from different topics are considered. Clustering techniques provide added value to identify typologies, but ...

    Article
    Open Access
    Background Somatosensory evoked potentials (SEP) may add substantial prognostic value in patients with acute ischemic stroke (AIS) and contribute to the selection of patients that may benefit from revascularization therapies ...

  • Effectively integrating research argumentation in syllabus learning: A case study of reading journal articles in four fourth-year engineering fluid mechanics courses 

    Gámez Montero, Pedro Javier; Rodero de Lamo, Lourdes (SAGE publishing, 2023-08-10)
    Article
    Open Access
    In an emerging trend in engineering education students are engaged in the scientific discovery process through reading about research published in articles rather than textbooks. A research-based and curriculum-oriented ...

  • Row mixture-based clustering with covariates for ordinal responses 

    Preedalikit, Kemmawadee; Fernández Martínez, Daniel; Liu, Ivy; McMillan, Louise; Nai Ruscone, Marta; Costilla, Roy (2023-07-22)
    Article
    Open Access
    Existing methods can perform likelihood-based clustering on a multivariate data matrix of ordinal data, using finite mixtures to cluster the rows (observations) of the matrix. These models can incorporate the main effects ...

  • MSMpred: interactive modelling and prediction of individual evolution via multistate models 

    Garmendia Bergés, Leire; Cortés Martínez, Jordi; Gómez Melis, Guadalupe (Springer Nature, 2023-05-24)
    Article
    Open Access
    Background: Modelling the course of a disease regarding severe events and identifying prognostic factors is of great clinical relevance. Multistate models (MSM) can be used to describe diseases or processes that change ...
