• On dynamic distribution of private keys over MANETs

  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 ...
• 'Ad-hoc' threshold broadcast encryption with shorter ciphertexts

  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 ...
• Relations between semantic security and anonymity in identity-based encryption

  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 ...

  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), ...
• An intelligent interface for drum pattern variation and comparative evaluation of algorithms

  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 ...
• Early positivity signals changes in an abstract linguistic pattern

  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 ...
• Early neural responses underlie advantages for consonance over dissonance

  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 ...
• Learning a new selection rule in visual and frontal cortex

  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, ...
• FUBImethod: Strategies to engage children in the co-design of Full-Body interactive experiences

  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 ...
• Human consciousness is supported by dynamic complex patterns of brain signal coordination

  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 ...
• Structural coronary artery remodelling in the rabbit fetus as a result of intrauterine growth restriction

  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 ...
• Potential and pitfalls of multi-armed bandits for decentralized spatial reuse in WLANs

  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 ...
• Melody extraction from polyphonic music signal susing pitch contour characteristics

  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 ...
• Selective sampling for beat tracking evaluation

  Holzapfel, Andre; Davies, Matthew E. P.; Zapata, José R.; Lobato Oliveira, João; Gouyon, Fabien (Institute of Electrical and Electronics Engineers (IEEE), 2012)
