  • Martí Juan, Gerard; Sanromà, Gerard; Piella Fenoy, Gemma (Public Library of Science (PLoS), 2019)
    Alzheimer’s disease (AD) affects millions of people and is a major rising problem in health care worldwide. Recent research suggests that AD could have different subtypes, presenting differences in how the disease develops. ...
  • Parés, Narcís, 1966-; Mairena, Maria Angeles; Mora Guiard, Joan; Malinverni, Laura; Padillo, Vanesa; Valero, Lilia; Hervás, Amaia; Parés, Narcís, 1966- (Elsevier, 2019)
    Background Game-based interventions that involve the use of technology have shown to facilitate motivation and learning processes in children with Autism Spectrum Disorders (ASD). The purpose of this observational study ...
  • Porcaro, Lorenzo; Saggion, Horacio (Computing Research Center (CIC-IPN), 2019)
    Recognizing Musical Entities is important for Music Information Retrieval (MIR) since it can improve the performance of several tasks such as music recommendation, genre classification or artist similarity. However, ...
  • Stefanakis, Nikolaos (Acoustical Society of America, 2019)
    Several applications in spatial audio signal processing benefit from the knowledge of the diffuseness of the sound field. In this paper, several experiments are performed to determine the response of a tetrahedral microphone ...
  • Basart i Muñoz, Josep M.; Farrús, Mireia; Serra, Montse (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    According to the Encyclopadia Britannica, the establishment of the Royal Society of London for Improving Natural Knowledge (Royal Society), the "oldest national scientific society in the world," was on November 28, 1660. ...
  • Caro Repetto, Rafael (Universitat Autònoma de Barcelona. Grupo de Investigación Inter Asia. Centro de Estudios e Investigación sobre Asia Oriental, 2012)
    Con el objetivo de evaluar las principales tendencias que afectan a las producciones contemporáneas de ópera de Beijing, el presente artículo estudiará los procesos por los cuales a lo largo del siglo XX y la primera década ...
  • Marín, Victoria I.; Asensio-Pérez, Juan I.; Villagrá-Sobrino, Sara L.; Hernández Leo, Davinia; García-Sastre, Sara (Taylor & Francis, 2018)
    This article describes a study of online collaborative design in the context of teacher professional development. Twenty-five teachers from different Spanish universities participated in the online course. The aim was to ...
  • Daza, Vanesa; Morillo, Paz; Ràfols, Carla (Elsevier, 2007)
    Identity-Based cryptography has been proposed in mobile ad-hoc networks (MANETs) to provide security. However, the figure of the Private Key Generator (PKG) is not adequate in the MANET setting, since it may not be ...
  • Daza, Vanesa; Herranz, Javier; Morillo, Paz; Ràfols, Carla (Elsevier, 2008)
    In a threshold broadcast encryption scheme, a sender chooses (ad-hoc) a set of n receivers and a threshold t, and then encrypts a message by using the public keys of all the receivers, in such a way that the original plaintext ...
  • Herranz, Javier; Laguillaumie, Fabien; Ràfols, Carla (Elsevier, 2011)
    Semantic security and anonymity are the two main properties that an identity-based encryption scheme can satisfy. Such properties can be de ned in either an adaptive or a selective scenario, which di er on the moment ...
  • Attrapadung, Nuttapong; Herranz, Javier; Laguillaumie, Fabien; Libert, Benoît; De Panafieu, Elie; Ràfols, Carla (Elsevier, 2012)
    Attribute-based encryption (ABE), as introduced by Sahai and Waters, allows for fine- grained access control on encrypted data. In its key-policy flavor (the dual ciphertext-policy scenario proceeds the other way around), ...
  • Vogl, Richard; Leimeister, Matthias; Nuanáin, Carthach Ó; Hlatky, Michael; Jordà Puig, Sergi; Knees, Peter (Audio Engineering Society, 2016)
    Drum tracks of electronic dance music pieces are a central and style-defining element. Yet,creating them can be a cumbersome task, mostly due to lack of appropriate tools and inputdevices. In this work we use a UI prototype ...
  • Monte Ordoño, Julia, 1989-; Toro Soto, Juan Manuel, 1976- (Public Library of Science (PLoS), 2017)
    The extraction of abstract structures from speech (or from gestures in the case of sign languages) has been claimed to be a fundamental mechanism for language acquisition. In the present study we registered the neural ...
  • Crespo Bojorque, Paola, 1985-; Monte Ordoño, Julia, 1989-; Toro Soto, Juan Manuel, 1976- (Elsevier, 2018)
    Consonant musical intervals tend to be more readily processed than dissonant intervals. In the present study, we explore the neural basis for this difference by registering how the brain responds after changes in consonance ...
  • van der Togt, Chris; Stănişor, Liviu; Pooresmaeili, Arezoo; Albantakis, Larissa; Deco, Gustavo; Roelfsema, Pieter R. (Oxford University Press, 2016)
    How do you make a decision if you do not know the rules of the game? Models of sensory decision-making suggest that choices are slow if evidence is weak, but they may only apply if the subject knows the task rules. Here, ...
  • Schaper, Marie-Monique; Iversen, Ole Sejer; Malinverni, Laura; Parés, Narcís, 1966- (Elsevier, 2019)
    In this paper, we present the FUBImethod, a method based on six stages to co-design interactive experiences based on Full-Body Interaction. The FUBImethod aims specifically to engage children in co-design processes and to ...
  • Demertzi, A.; Tagliazucchi, Enzo; Dehaene, Stanislas; Deco, Gustavo; Barttfeld, P.; Raimondo, F.; Martial, C.; Fernández-Espejo, D.; Rohaut, B.; Voss, H. U.; Schiff, N. D.; Owen, A. M.; Laureys, S.; Naccache, L.; Sitt, J. D. (American Association for the Advancement of Science (AAAS), 2019)
    Adopting the framework of brain dynamics as a cornerstone of human consciousness, we determined whether dynamic signal coordination provides specific and generalizable patterns pertaining to conscious and unconscious states ...
  • García Cañadilla, Patricia, 1985-; de Vries, Tom; González-Tendero, Anna; Bonnin, Anne; Gratacós Solsona, Eduard; Crispi Brillas, Fàtima; Bijnens, Bart; Zhang, Chong (Public Library of Science (PLoS), 2019)
    Intrauterine growth restriction (IUGR) is a fetal condition that affects up to 10% of all pregnancies and is associated with cardiovascular structural and functional remodelling that persists postnatally. Some studies have ...
  • Wilhelmi Roca, Francesc; Barrachina Muñoz, Sergio; Bellalta, Boris; Cano Bastidas, Cristina; Jonsson, Anders, 1973-; Neu, Gergely (Elsevier, 2019)
    Spatial Reuse (SR) has recently gained attention to maximize the performance of IEEE 802.11 Wireless Local Area Networks (WLANs). Decentralized mechanisms are expected to be key in the development of SR solutions for ...
  • Salamon, Justin J.; Gómez Gutiérrez, Emilia, 1975- (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    We present a novel system for the automatic extraction of the main melody from polyphonic music recordings. Our approach is based on the creation and characterisation of pitch contours, time continuous sequences of pitch ...
