  • Nakaki, Ayako; Urru, Andrea; Piella Fenoy, Gemma; Comte, Valentin; Pozo Mendoza, Óscar J., 1975-; Gómez-Gómez, Àlex; González Ballester, Miguel Ángel, 1973-; Gratacós Solsona, Eduard (Elsevier, 2023)
    Background: Maternal suboptimal nutrition and high stress levels are associated with adverse fetal and infant neurodevelopment. Objective: This study aimed to investigate if structured lifestyle interventions involving a ...
  • Torres Hernandez, Anthony; Brambila Paz, Fernando; Ramírez, Rafael, 1966- (MDPI, 2024)
    This paper presents the construction of a family of radial functions aimed at emulating the behavior of the radial basis function known as thin plate spline (TPS). Additionally, a method is proposed for applying fractional ...
  • Miniussi, Carlo; Harris, Justin A.; Ruzzoli, Manuela (Elsevier, 2013)
    Non-invasive brain stimulation (NIBS) is a method for the study of cognitive function that is quickly gaining popularity. It bypasses the correlative approaches of other imaging techniques, making it possible to establish ...
  • Melià Seguí, Joan; Garcia-Alfaro, Joaquin; Herrera-Joancomartí, Jordi (MDPI, 2013)
    Pseudorandom number generation (PRNG) is the main security tool in low-cost passive radio-frequency identification (RFID) technologies, such as EPC Gen2. We present a lightweight PRNG design for low-cost passive RFID tags, ...
  • Santolin, Chiara; Zacharaki, Konstantina; Toro Soto, Juan Manuel, 1976-; Sebastian-Galles, Nuria (Elsevier, 2024)
    Syllables are one of the fundamental building blocks of early language acquisition. From birth onwards, infants preferentially segment, process and represent the speech into syllable-sized units, raising the question of ...
  • Do, Heedong; Le, Namyoon; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    This paper deals with line-of-sight (LOS) MIMO communication via an intelligent reflecting surface (IRS). It is shown that the number of spatial degrees of freedom (DOF) afforded by this setting grows in proportion with ...
  • Mojahedian, Mohammad M.; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    An approach is presented to compute the capacity-achieving precoder and receiver for wide-aperture MIMO with uniform linear arrays in O(N2min) operations as opposed to the O(N2minNmax) required by the singular-value ...
  • Do, Heedong; Lee, Namyoon; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    Motivated by the widespread adoption of the parabolic wavefront model for line-of-sight (LOS) multiple-input multiple-output (MIMO) communication, this paper presents a comprehensive analysis of this model’s validity and ...
  • Ruffini, Giulio; Lopez-Sola, Edmundo; Vohryzek, Jakub; Sanchez Todo, Roser (MDPI, 2024)
    We explore the intersection of neural dynamics and the effects of psychedelics in light of distinct timescales in a framework integrating concepts from dynamics, complexity, and plasticity. We call this framework neural ...
  • Garriga, Roger; Gómez Cerdà, Vicenç; Lugosi, Gábor (Frontiers, 2024)
    Introduction: Individuals in the midst of a mental health crisis frequently exhibit instability and face an elevated risk of recurring crises in the subsequent weeks, which underscores the importance of timely intervention ...
  • Theophilou, Emily; Hernández Leo, Davinia; Gómez, Vicenç (Wiley, 2023)
    Background:Gender differences in the use of educational environments and socialmedia platforms have been a topic of interest in research. Several studies have exam-ined the disparities between female and male participants ...
  • Martins, Pedro; Boeckx, Cedric (Frontiers, 2014)
    There is still no categorical answer as to why humans, and no other species, have speech, or why speech is the way it is. Several purely anatomical arguments have been put forward, but they have been shown to be false, ...
  • Larrabide, Ignacio, 1978-; Aguilar, María Laura; Morales, Hernán G.; Geers, Adrianus Johannes; Kulcsár, Zsolt; Rüfenacht, Daniel; Frangi Caregnato, Alejandro (American Society of Neuroradiology, 2013)
    Background and purpose: Effects of blood flow modification by flow diverters are observed to lead often to aneurysm thrombosis and reverse remodeling. For this process, to further understand the potential roles of ...
  • Lange, Matthias; Di Marco, LY; Lekadir, Karim, 1977-; Lassila, Toni; Frangi Caregnato, Alejandro (Public Library of Science (PLoS), 2016)
    False tendons (FTs) are fibrous or fibromuscular bands that can be found in both the normal and abnormal human heart in various anatomical forms depending on their attachment points, tissue types, and geometrical properties. ...
  • Lallée, Stéphane; Verschure, Paul F. M. J. (MDPI, 2015)
    Robotic agents are spreading, incarnated as embodied entities, exploring the tangible world and interacting with us, or as virtual agents crawling over the web, parsing and generating data. In both cases, they require: (i) ...
  • Kjer, Hans Martin; Fagertun, Jens; Vera, Sergio; Gil, Debora; González Ballester, Miguel Ángel, 1973-; Paulsen, Rasmus (Elsevier, 2016)
    Better understanding of the anatomical variability of the human cochlear is important for the design and function of Cochlear Implants. Proper non-rigid alignment of high-resolution cochlear μCT data is a challenge for the ...
  • Kim, Hansung; Evans, Alun; Blat, Josep; Hilton, Adrian (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Recent developments of video and sensing technology have led to large volumes of digital media data. Current media production relies on videos from the principal camera together with a wide variety of heterogeneous source ...
  • Cabrero Daniel, Beatriz; Marques, Ricardo; Hoyet, Ludovic; Pettré, Julien; Blat, Josep (Wiley, 2022)
    Simulating crowds requires controlling a very large number of trajectories of characters and is usually performed using crowd steering algorithms. The question of choosing the right algorithm with the right parameter values ...
  • Marichal Baráibar, Sebastián; Rosales, Andrea; González Perilli, Fernando; Pires, Ana Cristina; Blat, Josep (Taylor & Francis, 2023)
    Physical manipulatives, such as rods or tiles, are widely used for mathematics learning, as they support embodied cognition, enable the execution of epistemic actions, and foster conceptual metaphors. Counting them, children ...
  • Becerra Fajardo, Laura; Minguillon, Jesus; Krob, Marc Oliver; Rodrigues, Camila; González Sánchez, Miguel; Megía-García, Álvaro; Redondo Galán, Carolina; Gutiérrez Henares, Francisco; Comerma-Montells, Albert; Del-Alma, Antonio J.; Gil-Agudo, Ángel; Grandas, Francisco; Schneider-Ickert, Andreas; Barroso, Filipe O.; Ivorra Cano, Antoni, 1974- (BioMed Central, 2024)
    Background: Recently we reported the design and evaluation of floating semi-implantable devices that receive power from and bidirectionally communicate with an external system using coupling by volume conduction. The ...
