  • Sahoo, Bikash; Pathak, Anagh; Deco, Gustavo; Banerjee, Arpan; Roy, Dipanjan (Elsevier, 2020)
    Healthy ageing is accompanied by changes to spontaneous electromagnetic oscillations. At the macroscopic scale, previous studies have quantified the basic features, e.g., power and frequencies in rhythms of interest from ...
  • Jonsson, Anders, 1973-; Jonsson, Peter; Lööw, Tomas (Elsevier, 2014)
    Causal graphs are widely used in planning to capture the internal structure of planning instances. Researchers have paid special attention to the subclass of planning instances with acyclic causal graphs, which in the past ...
  • 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 ...
  • Hindriks, Rikkert; Schmiedt, Joscha; Arsiwalla, Xerxes D.; Peter, Alina; Verschure, Paul F. M. J.; Fries, Pascal; Schmid, Michael C.; Deco, Gustavo (Public Library of Science (PLoS), 2017)
    Planar intra-cortical electrode (Utah) arrays provide a unique window into the spatial organization of cortical activity. Reconstruction of the current source density (CSD) underlying such recordings, however, requires ...
  • Mosayebi, Reza; Mojahedian, Mohammad Mahdi; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Drawing on the notion of parallel interference cancellation, this paper formulates a one-shot linear receiver for the uplink of centralized, possibly cloud-based, radio access networks (C-RANs) operating in a cell-free ...
  • Fedorov, Vadim; Arias Martínez, Pablo; Sadek, Rida; Facciolo Furlan, Gabriele; Ballester, Coloma (SIAM (Society for Industrial and Applied Mathematics), 2015)
    In this paper we study the problem of comparing two patches of images defined on Riemannian/nmanifolds which in turn can be defined by each image domain with a suitable metric depending on/nthe image. For that we single ...
  • Saenger Amoore, Victor Manuel; Ponce-Alvarez, Adrián; Adhikari, Mohit H.; Hagmann, Patric; Deco, Gustavo; Corbetta, Maurizio (Oxford University Press, 2017)
    The brain is a network that mediates information processing through a wide range of states. The extent of state diversity is a reflection of the entropy of the network. Here we measured the entropy of brain regions (nodes) ...
  • Adrián Ventura, Jesús; Costumero, Víctor; Parcet, Maria-Antònia; Ávila, César (Oxford University Press, 2019)
    Reinforcement Sensitivity Theory (RST) proposes a widely used taxonomy of human personality linked to individual differences at both behavioral and neuropsychological levels that describe a predisposition to psychopathology. ...
  • Sentürk, Sertan; Holzapfel, Andre; Serra, Xavier (Taylor & Francis (Routledge), 2014)
    The most relevant representations of music are notations and audio recordings, each of which emphasizes a particular perspective and promotes different approximations in the analysis and understanding of music. Linking ...
  • Ledberg, Anders; Robbe, David (Public Library of Science, 2011)
    The hippocampal theta rhythm is required for accurate navigation and spatial memory but its relation to the dynamics of/nlocomotion is poorly understood. We used miniature accelerometers to quantify with high temporal and ...
  • Ivorra Cano, Antoni, 1974-; Sánchez Velázquez, Patricia, 1985-; Castellví Fernández, Quim; Villanueva, Alberto; Iglesias Coma, Mar; Quesada Diez, Rita; Pañella Vilamú, Clara, 1987-; Cáceres Aguilar, Mario; Dorcaratto, Dimitri; Andaluz, Anna; Moll, Xavier; Burdío, José M.; Grande Posa, Luís; Burdío Pinilla, Fernando (Nature Publishing Group, 2017)
    Irreversible electroporation (IRE) has recently gained in popularity as an ablative technique, however little is known about its oncological long-term outcomes. To determine the long-time survival of animals treated with ...
  • Celma Miralles, Alexandre, 1991-; De Menezes, Robert F.; Toro Soto, Juan Manuel, 1976- (Frontiers, 2016)
    Recent research has demonstrated top–down effects on meter induction in the auditory modality. However, little is known about these effects in the visual domain, especially without the involvement of motor acts such as ...
  • Joshi, Ricky S.; Rigau, Maria; García-Prieto, Carlos A.; Castro de Moura, Manuel; Piñeyro, David; Moran, Sebastian; Davalos, Veronica; Carrión, Pablo; Ferrando-Bernal, Manuel, 1990-; Olalde Marquínez, Íñigo, 1987-; Lalueza Fox, Carles, 1965-; Navarro i Cuartiellas, Arcadi, 1969-; Fernández-Tena, Carles; Aspandi, Decky; Sukno, Federico Mateo; Binefa i Valls, Xavier; Valencia, Alfonso; Esteller, Manel (Elsevier, 2022)
    The human face is one of the most visible features of our unique identity as individuals. Interestingly, monozygotic twins share almost identical facial traits and the same DNA sequence but could exhibit differences in ...
  • López-González, Ane; Panda, Rajanikant; Ponce-Alvarez, Adrián; Zamora-López, Gorka; Escrichs, Anira; Martial, Charlotte; Thibaut, Aurore; Gosseries, Olivia; Kringelbach, Morten L.; Annen, Jitka; Laureys, Steven; Deco, Gustavo (Nature Research, 2021)
    Low-level states of consciousness are characterized by disruptions of brain activity that sustain arousal and awareness. Yet, how structural, dynamical, local and network brain properties interplay in the different levels ...
  • Vila-Vidal, Manel, 1991-; Pérez-Enríquez, Carmen; Principe, Alessandro; Rocamora, Rodrigo; Deco, Gustavo; Tauste Campo, Adrià, 1982- (Elsevier, 2020)
    The spatial mapping of localized events in brain activity critically depends on the correct identification of the pattern signatures associated with those events. For instance, in the context of epilepsy research, a number ...
  • Wu, Yongpeng; Wing Kwan Ng, Derrick; Wen, Chao-Kai; Schober, Robert; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    This paper investigates the design of precoders for single-user multiple-input multiple-output (MIMO) channels, and, in particular, for finite-alphabet signals. Based on an asymptotic expression for the mutual information ...
  • Borda Fortuny, Cristina; Tong, Kin-Fai; Chetty, Kevin (Institution of Engineering and Technology (IET), 2018)
    A frequency agile Vivaldi antenna whose operating frequency band can be switched between two selected bands is proposed in this study for spectrum monitoring and cognitive radio applications. A radiofrequency (RF) switch ...
  • Boutros, Joseph Jean; Guillén i Fábregas, A. (Albert); Biglieri, Ezio; Zémor, Gilles (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    We design powerful low-density parity-check (LDPC) codes with iterative decoding for the block-fading channel. We first study the case of maximum-likelihood decoding, and show that the design criterion is rather straightforward. ...
  • Pazó, Diego; Montbrió, Ernest, 1974- (American Physical Society, 2014)
    Large communities of biological oscillators show a prevalent tendency to self-organize in time. This/ncooperative phenomenon inspired Winfree to formulate a mathematical model that originated the theory of/nmacroscopic ...
  • Ballester, Coloma; Caselles, Vicente; González Hidalgo, Manuel (Unión Matemática Argentina, 1998)
    We study the Affine Total Variation, a magnitude measuring the affine complexity of finite unions of continua, in particular, Jordan curves, appearing in an affine invariant analogue of Mumford-Shah energy functional used ...
