    Background: Cardiovascular magnetic resonance (CMR) imaging has been used to visualise post-ablation atrial scar (PAAS), generally employing a three-dimensional (3D) late gadolinium enhancement (LGE) technique. However the ...
  • Garreta-Domingo, Muriel; Hernández Leo, Davinia; Sloep, Peter B. (Australasian Society for Computers in Learning in Tertiary Education (ASCILITE), 2018)
    The design of learning opportunities is an integral part of the work of all educators. However, educators often lack the design skills and knowledge that professional designers have. One of these basic skills is related ...

    Background. Spread hepatic tumours are not suitable for treatment either by surgery or conventional ablation methods. The aim of this study was to evaluate feasibility and safety of selectively ...

    Epidemiological studies mostly focus on single environmental exposures. This study aims to systematically assess associations between a wide range of prenatal and childhood environmental exposures and cognition. The study ...
  • Rello, Luz, 1984-; Baeza Yates, Ricardo (Springer, 2017)
    The presentation of a text has a significant effect on the reading speed of people with dyslexia. This paper presents a set of recommendations to customize texts on a computer screen in a more accessible way for this target ...
  • Vives, Marc-Lluís, 1991-; Repke, Lydia; Costa, Albert, 1970- (Cambridge University Press, 2018)
    Ikizer and Ramirez-Esparza (2017) reported a study suggesting that bilingualism may have a positive impact on people's social skills. They found that a) bilinguals scored higher on a scale that is supposed to reveal social ...
  • Codina Filbà, Joan; Bouayad-Agha, Nadjet; Burga Díaz, Alicia; Casamayor, Gerard; Mille, Simon; Müller, Andreas; Saggion, Horacio; Wanner, Leo (Elsevier, 2016)
    Patent search is recall-driven, which goes hand in hand with at least a partial sacrifice of precision. As a consequence, patent analysts have to regularly view and examine a large amount of patents. This implies a very ...
  • Montbrió, Ernest, 1974-; Pazó, Diego (American Physical Society, 2018)
    The Kuramoto model (KM) is a theoretical paradigm for investigating the emergence of rhythmic activity in large populations of oscillators. A remarkable example of rhythmogenesis is the feedback loop between excitatory (E) ...
  • Esnaola Acebes, Jose M.; Roxin, Alex; Avitabile, Daniele; Montbrió, Ernest, 1974- (American Physical Society, 2017)
    We investigate the modes of oscillation of heterogeneous ring networks of quadratic integrate-and-fire (QIF) neurons with nonlocal, space-dependent coupling. Perturbations of the equilibrium state with a particular wave ...
  • Gallego, Rafael; Montbrió, Ernest, 1974-; Pazó, Diego (American Physical Society, 2017)
    Fifty years ago Arthur Winfree proposed a deeply influential mean-field model for the collective synchronization of large populations of phase oscillators. Here we provide a detailed analysis of the model for some special, ...
  • Devalle, Federico; Montbrió, Ernest, 1974-; Pazó, Diego (American Physical Society, 2018)
    We analyze a large system of heterogeneous quadratic integrate-and-fire (QIF) neurons with time delayed, all-to-all synaptic coupling. The model is exactly reduced to a system of firing rate equations that is exploited to ...
  • Gilson, Matthieu; Kouvaris, Nikos; Deco, Gustavo; Zamora-López, Gorka (American Physical Society, 2018)
    Graph theory constitutes a widely used and established field providing powerful tools for the characterization of complex networks. The intricate topology of networks can also be investigated by means of the collective ...
  • Strijkers, Kristof; Costa, Albert, 1970-; Pulvermüller, Friedemann (Elsevier, 2017)
    Language production models typically assume that retrieving a word for articulation is a sequential process with substantial functional delays between conceptual, lexical, phonological and motor processing, respectively. ...
  • Hindriks, Rikkert; Micheli, C.; Bosman, Conrado A.; Oostenveld, R.; Lewis, C.; Mantini, Dante; Fries, Pascal; Deco, Gustavo (Elsevier, 2018)
    The discovery of hemodynamic (BOLD-fMRI) resting-state networks (RSNs) has brought about a fundamental shift in our thinking about the role of intrinsic brain activity. The electrophysiological underpinnings of RSNs remain ...
  • Dalmau, Víctor; Krokhin, Andrei; Manokaran, Rajsekar (Elsevier, 2018)
    We study the approximability of (Finite-)Valued Constraint Satisfaction Problems (VCSPs) with a fixed finite constraint language Γ consisting of finitary functions on a fixed finite domain. Ene et al. have shown that, under ...
  • Righi, Valeria; Sayago Barrantes, Sergio; Blat, Josep (Elsevier, 2017)
    This paper addresses a number of challenges HCI designers and researchers deal with when designing digital technologies for older people. We conducted a 5-year research-through-design study, which combined ethnography, ...
  • Romero García, Daniel; Sebastián Aguilar, Rafael, 1978-; Bijnens, Bart; Zimmerman, Viviana; Boyle, Patrick M.; Vigmond, Edward J.; Frangi Caregnato, Alejandro (Springer, 2010)
    Heart failure leads to gross cardiac structural changes. While cardiac resynchronization therapy (CRT) is a recognized treatment for restoring synchronous activation, it is not clear how changes in cardiac shape and size ...
  • Pozo Soler, José Ma. (José María); Villa-Uriol, Maria-Cruz; Frangi Caregnato, Alejandro (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    This paper introduces and evaluates a fast exact algorithm and a series of faster approximate algorithms for the computation of 3D geometric moments from an unstructured surface mesh of triangles. Being based on the object ...

    Ketamine is a dissociative anesthetic drug, which has more recently emerged as a rapid-acting antidepressant. When acutely administered at subanesthetic doses, ketamine causes cognitive deficits like those observed in ...
  • Slizovskaia, Olga; Haro Ortega, Gloria; Gómez Gutiérrez, Emilia, 1975- (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    In music source separation, the number of sources may vary for each piece and some of the sources may belong to the same family of instruments, thus sharing timbral characteristics and making the sources more correlated. ...
