  • Van Schependom, Jeroen; Vidaurre, Diego; Costers, Lars; Sjøgård, Martin; Sima, Diana M.; Smeets, Dirk; D'hooghe, Marie Beatrice; D'haeseleer, Miguel; Deco, Gustavo; Wens, Vincent; De Tiège, Xavier; Goldman, Serge; Woolrich, Mark W.; Nagels, Guy (Elsevier, 2021)
    In multiple sclerosis, the interplay of neurodegeneration, demyelination and inflammation leads to changes in neurophysiological functioning. This study aims to characterize the relation between reduced brain volumes and ...
  • Zinemanas, Pablo; Rocamora, Martín; Miron, Marius; Font Corbera, Frederic; Serra, Xavier (MDPI, 2021)
    Deep learning models have improved cutting-edge technologies in many research areas, but their black-box structure makes it difficult to understand their inner workings and the rationale behind their predictions. This may ...
  • Herlitze, Stefan; Kringelbach, Morten L.; Deco, Gustavo (Wiley, 2021)
    What is the effect of activating a single modulatory neuronal receptor type on entire brain network dynamics? Can such effect be isolated at all? These are important questions because characterizing elementary neuronal ...
  • Andrzejak, Ralph Gregor (American Institute of Physics (AIP), 2021)
    Complex-valued quadratic maps either converge to fixed points, enter into periodic cycles, show aperiodic behavior, or diverge to infinity. Which of these scenarios takes place depends on the map’s complex-valued parameter ...
  • Javaid, Misbah; Estivill Castro, Vladimir (MDPI, 2021)
    Typically, humans interact with a humanoid robot with apprehension. This lack of trust can seriously affect the effectiveness of a team of robots and humans. We can create effective interactions that generate trust by ...
  • Ferraro, Andrés; Favory, Xavier; Drossos, Konstantinos; Kim, Yuntae; Bogdanov, Dmitry (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Modeling various aspects that make a music piece unique is a challenging task, requiring the combination of multiple sources of information. Deep learning is commonly used to obtain representations using various sources ...
  • Dovelos, Konstantinos; Matthaiou, Michail; Ngo, Hien Quoc; Bellalta, Boris (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Terahertz (THz) communication is widely considered as a key enabler for future 6G wireless systems. However, THz links are subject to high propagation losses and inter-symbol interference due to the frequency selectivity ...
  • Coderch-Navarro, Sergi; Berjano, Enrique J.; Camara, Oscar; González-Suárez, Ana (Taylor & Francis, 2021)
    Purpose: While the standard setting during radiofrequency catheter ablation (RFCA) consists of applying low power for long times, a new setting based on high power and short duration (HPSD) has recently been suggested as ...
  • Hodzic, Amir; Bernardino Perez, Gabriel; Legallois, Damien; Gendron, Patrick; Langet, Hélène; De Craene, Mathieu; González Ballester, Miguel Ángel, 1973-; Milliez, Paul; Normand, Hervé; Bijnens, Bart; Saloux, Eric; Tournoux, Francois (MDPI, 2021)
    Few data exist concerning the right ventricular (RV) physiological adaptation in American-style football (ASF) athletes. We aimed to analyze the RV global and regional responses among ASF-trained athletes. Fifty-nine (20 ...
  • Beardsley, Marc; Albó, Laia; Aragón, Pablo; Hernández Leo, Davinia (Wiley, 2021)
    To identify factors that can contribute toward supporting educator adoption of digital technologies beyond the emergency remote teaching response to COVID‐19, we investigated how teachers’ motivation and abilities related ...
  • Furelos Blanco, Daniel; Law, Mark; Jonsson, Anders, 1973-; Broda, Krysia; Russo, Alessandra (AI Access Foundation, 2021)
    In this paper we present ISA, an approach for learning and exploiting subgoals in episodic reinforcement learning (RL) tasks. ISA interleaves reinforcement learning with the induction of a subgoal automaton, an automaton ...
  • Samanta, Bidisha; De, Abir; Jana, Gourhari; Gómez, Vicenç; Chattaraj, Pratim Kumar; Ganguly, Niloy; Gomez-Rodriguez, Manuel (Journal of Machine Learning Research, 2020)
    Deep generative models have been praised for their ability to learn smooth latent representations of images, text, and audio, which can then be used to generate new, plausible data. Motivated by these success stories, there ...
  • López-Moliner, Joan; Soto-Faraco, Salvador, 1970- (Association for Research in Vision and Ophthalmology (ARVO), 2007)
    There is a growing body of knowledge about the behavioral and neural correlates of cross-modal interactions in the perception of motion direction, as well as about the computations that underlie unimodal visual speed ...
  • Vigué Guix, Irene; Morís Fernández, Luis, 1982-; Torralba, Mireia; Ruzzoli, Manuela; Soto-Faraco, Salvador, 1970- (Wiley, 2020)
    Electrical brain oscillations reflect fluctuations in neural excitability. Fluctuations in the alpha band (α, 8–12 Hz) in the occipito‐parietal cortex are thought to regulate sensory responses, leading to cyclic variations ...
  • Roma Trepat, Gerard; Herrera Boyer, Perfecto, 1964-; Zanin, Massimiliano; Toral, Sergio L.; Font Corbera, Frederic; Serra, Xavier (Inderscience Enterprises Ltd, 2012)
    Sharing communities are changing the way audio clips are obtained in several areas, ranging from music to game design. The motivations for people to record and upload sounds to these sites are likely to be related to social ...
  • Tamir, Ran; Merhav, Neri; Weinberger, Nir; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    This work studies the deviations of the error exponent of the constant composition code ensemble around its expectation, known as the error exponent of the typical random code (TRC). In particular, it is shown that the ...
  • Morís Fernández, Luis, 1982-; Vadillo, Miguel A. (Royal Society, 2020)
    In the present article, we explore the influence of undisclosed flexibility in the analysis of reaction times (RTs). RTs entail some degrees of freedom of their own, due to their skewed distribution, the potential presence ...
  • Higueras-Esteban, Alfredo; Delgado-Martínez, Ignacio; Serrano, Laura; Principe, Alessandro; Pérez Enríquez, Carmen; González Ballester, Miguel Ángel, 1973-; Rocamora Zúñiga, Rodrigo Alberto; Conesa Bertran, Gerardo; Serra, Luis (Elsevier, 2021)
    Background and objective: We present SYLVIUS, a software platform intended to facilitate and improve the complex workflow required to diagnose and surgically treat drug-resistant epilepsies. In complex epilepsies, additional ...
  • Zacharaki, Konstantina; Sebastián Gallés, Núria (Elsevier, 2021)
    Infants can discriminate languages that belong to different rhythmic classes at birth. The ability to perform within-class discrimination emerges around the fifth month of life. The cues that infants use to discriminate ...
