  • Trujillo Guillén, Macarena; Castellví Fernández, Quim; Burdío Pinilla, Fernando; Ivorra Cano, Antoni, 1974-; Andaluz, Anna; Sanchez Velazquez Patricia; Berjano, Enrique J. (Taylor & Francis (Routledge), 2013)
    Purpose: To assess the feasibility of a hybrid ablative technique based on applying electroporation (EP) pulses just before conducting radiofrequency ablation (RFA). The rationale was that the EP-induced reduction in blood ...
  • Hindriks, Rikkert; Adhikari, Mohit H.; Murayama, Yusuke; Ganzetti, Marco; Mantini, Dante; Logothetis, N.; Deco, Gustavo (Elsevier, 2016)
    During the last several years, the focus of research on resting-state functional magnetic resonance imaging (fMRI) has shifted from the analysis of functional connectivity averaged over the duration of scanning sessions ...
  • Tulino, Antonia M.; Lozano Solsona, Angel; Verdú, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2006)
    We characterize the capacity-achieving input covariance for multi-antenna channels known instantaneously at the receiver and in distribution at the transmitter. Our characterization, valid for arbitrary numbers of antennas, ...
  • Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2003)
    The simultaneous use of multiple transmit and receive antennas can unleash very large capacity increases in rich multipath environments. Although such capacities can be approached by layered multi-antenna architectures ...
  • Huguet, Marina; Tobón Gómez, Catalina, 1981-; Bijnens, Bart; Frangi Caregnato, Alejandro; Petit i Guinovart, Màrius (BioMed Central, 2009)
    Blunt chest traumas are a clinical challenge, both for diagnosis and treatment. The use of/nCardiovascular Magnetic Resonance can play a major role in this setting. We present two cases: a/n12-year-old boy and 45-year-old ...
  • Oubel, E.; De Craene, Mathieu; Hero, A.O.; Pourmorteza, A.; Huguet, Marina; Avegliano, Gustavo P.; Bijnens, Bart; Frangi Caregnato, Alejandro (Elsevier, 2011)
    Image registration has been proposed as an automatic method for recovering cardiac displacement fields from Tagged Magnetic Resonance Imaging (tMRI) sequences. Initially performed as a set of pairwise registrations, these ...
  • Mas‐Stachurska, Aleksandra; Siegert, Anna‐Maria; Batlle, Montserrat; Gorbenko del Blanco, Darya; Meirelles, Thayna; Rubies, Cira; Bonorino, Fabio; Serra‐Peinado, Carla; Bijnens, Bart; Baudin, Julio; Sitges, Marta; Mont, Lluís; Guasch, Eduard; Egea, Gustavo (Wiley, 2017)
    Marfan syndrome (MF) leads to aortic root dilatation and a predisposition to aortic dissection, mitral valve prolapse, and primary and secondary cardiomyopathy. Overall, regular physical exercise is recommended for a healthy ...
  • Moreno Bote, Rubén; Drugowitsch, Jan (Nature Research, 2015)
    While the brain uses spiking neurons for communication, theoretical research on brain computations has mostly focused on non-spiking networks. The nature of spike-based algorithms that achieve complex computations, such ...
  • Albantakis, Larissa; Deco, Gustavo (Public Library of Science, 2011)
    Attractor networks successfully account for psychophysical and neurophysiological data in various decision-making tasks./nEspecially their ability to model persistent activity, a property of many neurons involved in ...
  • Serrà Julià, Joan; Zanin, Massimiliano; Herrera Boyer, Perfecto, 1964-; Serra, Xavier (Elsevier, 2012)
    The use of community detection algorithms is explored within the framework of cover song identification, i.e. the automatic detection of different audio renditions of the same underlying musical piece. Until now, this task ...
  • Piella Fenoy, Gemma; De Craene, Mathieu; Bijnens, Bart; Tobón Gómez, Catalina, 1981-; Huguet, Marina; Avegliano, Gustavo P.; Frangi Caregnato, Alejandro (Elsevier, 2010)
    Introducción y objetivos. Se ha señalado que, en la miocardiopatía hipertrófica (MCH), la desorganización de las fibras regionales da lugar a segmentos en los que la deformación es nula o está gravemente reducida, y que ...
  • Sánchez Martínez, Sergio; Duchateau, Nicolas; Erdei, Tamas; Fraser, Alan G.; Bijnens, Bart; Piella Fenoy, Gemma (Elsevier, 2017)
    We propose an independent objective method to characterize different patterns of functional responses to stress in the heart failure with preserved ejection fraction (HFPEF) syndrome by combining multiple temporally-aligned ...
  • Martin, David; Aiello, Luca Maria; Grabowicz, Przemyslaw; Jaimes Larrarte, Alejandro; Baeza-Yates, Ricardo (SpringerOpen, 2014)
    Social groups play a crucial role in online social media because they form the basis for user participation and engagement. Although widely studied in their static and evolutionary aspects, no much attention has been devoted ...
  • Sitges, Marta; Merino, Beatriz; Butakoff, Constantine; Sanz de la Garza, Maria; Paré, Carles; Montserrat, Silvia; Vidal, Barbara; Azqueta, Manel; Sarquella-Brugada, Georgia; Gutierrez, Josep Antoni; Canal, Ramon; Brugada, Josep; Bijnens, Bart (Springer, 2017)
    Background: The significance and spectrum of reduced right ventricular (RV) deformation, reported in endurance athletes, is unclear. Purpose: to comprehensively analyze the cardiac performance at rest of athletes, especially ...
  • Hizanidis, Johanne; Kouvaris, Nikos; Zamora-López, Gorka; Díaz-Guilera, Albert; Antonopoulos, Chris G. (Nature Publishing Group, 2016)
    Chimera states, namely the coexistence of coherent and incoherent behavior, were previously analyzed in complex networks. However, they have not been extensively studied in modular networks. Here, we consider a neural ...
  • Serrà Julià, Joan; Gómez Gutiérrez, Emilia, 1975-; Herrera Boyer, Perfecto, 1964-; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We present a new technique for audio signal comparison based on tonal subsequence alignment and its application to detect cover versions (i.e., different performances of the same underlying musical piece). Cover song ...
  • Font Corbera, Frederic; Serrà Julià, Joan; Serra, Xavier (Elsevier, 2014)
    Online sharing platforms often rely on collaborative tagging systems for annotating content. In this way, users themselves annotate and describe the shared contents using textual labels, commonly called tags. These annotations ...
  • Espinosa-Anke, Luis (Elsevier, 2013)
    This paper proposes an approach to classify definitions as they appear in popularizing texts. Following the function theory of/nlexicography (Bergenholtz and Tarp, 2003), we propose a user-centered classification that ...
  • Bel Rafecas, Núria; Diz Pico, Jorge; Marimon, Montserrat; Pocostales Mercè, Joel (Sociedad Española para el Procesamiento del Lenguaje Natural (SEPLN), 2017)
    We present the system for the classification of sentences and short texts into Marketing Mix classes developed within the LPS-BIGGER project. The system classifies short texts from Social Media into categories that are ...
