  • Schedl, Markus; Gómez Gutiérrez, Emilia, 1975-; Trent, Erika S.; Tkalčič, Marko; Eghbal-Zadeh, Hamid; Martorell Domínguez, Agustín (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    This study deals with the strong relationship between emotions and music, investigating three main research questions: (RQ1) Are there differences in human music perception (e.g., emotions, tempo, instrumentation, and ...
  • Rodriguez-Cuadrado, Sara; Baus, Cristina; Costa, Albert, 1970- (MDPI, 2019)
    Word reduction refers to how predictable words are shortened in features such as duration, intensity, or pitch. However, its origin is still unclear: Are words reduced because it is the second time that conceptual ...
  • El Ayach, Omar; Lozano Solsona, Angel; Heath, R. W., Jr. (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    Interference alignment (IA) is a cooperative transmission strategy that, under some conditions,/nachieves the interference channel’s maximum number of degrees of freedom. Realizing IA gains,/nhowever, is contingent upon ...
  • Branzi, Francesca Martina, 1984-; Calabria, Marco; Boscarino, Maria Lucrezia; Costa, Albert, 1970- (Elsevier, 2016)
    We explored the overlap between bilingual language control (bLC) and domain-general executive control (EC) by focusing on inhibitory control processes. We tested 62 bilinguals in linguistic and non-linguistic switching ...
  • Bellalta, Boris; Barceló Vicens, Jaume; Staehle, Dirk; Vinel, Alexey; Oliver Riera, Miquel (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    Multi-user spatial multiplexing combined with packet aggregation can significantly increase the performance of Wireless Local Area Networks (WLANs). In this letter, we present and evaluate a simple technique to perform ...
  • Carrillo, José; Caselles, Vicente; Moll, Salvador (London Mathematical Society, 2013)
    We study the relativistic heat equation in one space dimension. We prove a local regularity result when the initial datum is locally Lipschitz in its support. We propose a numerical scheme that captures the known features ...
  • Timmer, Kalinka; Calabria, Marco; Branzi, Francesca Martina, 1984-; Baus, Cristina; Costa, Albert, 1970- (Frontiers, 2018)
    Bilingual speakers are suggested to use control processes to avoid linguistic interference from the unintended language. It is debated whether these bilingual language control (BLC) processes are an instantiation of the ...
  • Chicharro Raventós, Daniel (Springer, 2011)
    Spectral measures of causality are used to explore the role of different rhythms in the causal connectivity between brain regions. We study several spectral measures related to Granger causality, comprising the bivariate ...
  • Runnqvist, Elin; Strijkers, Kristof; Sadat Schaffai, Jasmin, 1982-; Costa, Albert, 1970- (Frontiers Media, 2011)
    Despite a large amount of psycholinguistic research devoted to the issue of processing differences between a first and a second language, there is no consensus regarding the locus where these emerge or the mechanism behind ...
  • Baus, Cristina; Costa, Albert, 1970- (Elsevier, 2015)
    This study investigates the temporal dynamics of sign production and how particular aspects of the signed modality influence the early stages of lexical access. To that end, we explored the electrophysiological correlates ...
  • Deco, Gustavo; Jirsa, Viktor K. (Society for Neuroscience, 2012)
    The ongoing activity of the brain at rest, i.e., under no stimulation and in absence of any task, is astonishingly highly structured into/nspatiotemporal patterns. These spatiotemporal patterns, called resting state networks, ...
  • Barrachina Muñoz, Sergio; Wilhelmi, Francesc; Bellalta, Boris (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    In order to dynamically adapt the transmission bandwidth in wireless local area networks (WLANs), dynamic channel bonding (DCB) was introduced in IEEE 802.11n. It has been extended since then, and it is expected to be a ...
  • Costumero, Víctor; Bueichekú, Elisenda; Adrián Ventura, Jesús; Ávila, César (Springer, 2020)
    Current evidence suggests that volitional opening or closing of the eyes modulates brain activity and connectivity. However, how the eye state influences the functional connectivity of the primary visual cortex has been ...
  • Kappen, Hilbert J.; Gómez, Vicenç; Opper, Manfred (Springer, 2012)
    We reformulate a class of non-linear stochastic optimal control problems introduced by Todorov (in Advances in Neural Information Processing Systems, vol. 19, pp. 1369-1376, 2007) as a Kullback-Leibler (KL) minimization ...
  • Buehlmann, Andrés; Deco, Gustavo (Public Library of Science (PLoS), 2010)
    In recent experimental work it has been shown that neuronal interactions are modulated by neuronal synchronization and that this modulation depends on phase shifts in neuronal oscillations. This result suggests that ...
  • Marques, Ricardo; Bouville, Christian; Bouatouch, Kadi (Wiley, 2018)
    This paper proposes optimal quadrature rules over the hemisphere for the shading integral. We leverage recent work regarding the theory of quadrature rules over the sphere in order to derive a new theoretical framework for ...
  • Bahrehmand, Arash; Batard, Thomas; Marques, Ricardo; Evans, Alun Thomas; Blat, Josep (Elsevier, 2017)
    Computational design is one of the most common tasks of immersive computer graphics projects, such as games, virtual reality and special effects. Layout planning is a challenging phase of architectural design, which requires ...
  • Rankothge, Windhya; Le, Franck; Russo, Alessandra; Lobo, Jorge (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    With the introduction of network function virtualization technology, migrating entire enterprise data centers into the cloud has become a possibility. However, for a cloud service provider (CSP) to offer such services, ...
  • Lozano Solsona, Angel; Tulino, Antonia M.; Verdú, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    This paper formulates power allocation policies that maximize the region of mutual informations/nachievable in multiuser downlink OFDM channels. Arbitrary partitioning of/nthe available tones among users and arbitrary ...
  • Lozano Solsona, Angel; Tulino, Antonia M.; Verdú, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2006)
    The mutual information of independent parallel Gaussian-noise channels is maximized, under an average power constraint, by independent Gaussian inputs whose power is allocated according to the waterfilling policy. In ...
