  • Lamarca, Meritxell; Sala, Josep; Rodríguez, Eduardo; Martínez, Alfonso (Springer, 2005)
    The evaluation of the union bound for theber of Reed-Solomon/Convolutional concatenated codes indicates that their performance might largely improve through the application of soft iterative decoders. This paper presents ...
  • Guillén i Fàbregas, Albert; Land, Ingmar; Martinez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    This paper determines the range of feasible values of standard error exponents for binary-input memoryless symmetric channels of fixed capacity C and shows that extremes are attained by the binary symmetric and the binary ...
  • Scarlett, Jonathan; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This paper considers the problem of channel coding with a given (possibly suboptimal) maximum-metric decoding rule. A cost-constrained random-coding ensemble with multiple auxiliary costs is introduced, and is shown to ...
  • Scarlett, Jonathan; Peng, Li; Merhav, Neri; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This paper studies expurgated random-coding bounds and exponents for channel coding with a given (possibly suboptimal) decoding rule. Variations of Gallager's analysis are presented, yielding several asymptotic and ...
  • Asyhari, A. Taufiq; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    We study transmission over multiple-input multiple-output block-fading channels with imperfect channel state information (CSI) at both the transmitter and receiver. In particular, based on mismatched decoding theory for a ...
  • Espinosa-Anke, Luis; Ronzano, Francesco; Saggion, Horacio (Springer, 2015)
    Hypernym extraction is a crucial task for semantically motivated NLP tasks such as taxonomy and ontology learning, textual entailment or paraphrase identification. In this paper, we describe an approach to hypernym extraction ...
  • Tauste Campo, Adrià; Vazquez-Vilar, Gonzalo; Guillén i Fàbregas, Albert; Koch, Tobias; Martinez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This paper studies the random-coding exponent of joint source-channel coding for a scheme where source messages are assigned to disjoint subsets (referred to as classes), and codewords are independently generated according ...
  • Scarlett, Jonathan; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    This paper studies the second-order asymptotics of coding rates for the discrete memoryless multiple-access channel (MAC) with a fixed target error probability. Using constant-composition random coding, coded time-sharing, ...
  • Scarlett, Jonathan; Somekh-Baruch, Anelia; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    This paper studies the mismatched decoding problem for binary-input discrete memoryless channels. An example is provided for which an achievable rate based on superposition coding exceeds the Csiszár-Körner-Hui rate, thus ...
  • Vazquez-Vilar, Gonzalo; Tauste Campo, Adrià; Guillén i Fàbregas, Albert; Martinez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Two alternative exact characterizations of the minimum error probability of Bayesian M-ary hypothesis testing are derived. The first expression corresponds to the error probability of an induced binary hypothesis test and ...
  • Scarlett, Jonathan; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    This paper studies multiuser random coding techniques for channel coding with a given (possibly suboptimal) decoding rule. For the mismatched discrete memoryless multiple-access channel, an error exponent is obtained that ...
  • Rodríguez, Sonia; Gómez Gutiérrez, Emilia, 1975-; Cuesta i Mussarra, Helena (Folk Music Analysis, 2018)
    This work deals with the automatic transcription and characterization of flamenco guitar, with a focus on short melodic interludes improvised between sung verses. These are called falsetas in the flamenco argot and are ...
  • Couñago, F.; Rodríguez de Dios, Núria; Taboada, B. (Elsevier, 2018)
    OBJECTIVES: The role of surgery in stage IIIA-N2 non-small cell lung cancer (NSCLC) is an actively debated in oncology. To evaluate the value of surgery in this patient population, we conducted a multi-institutional ...

    The vast majority of microfluidic systems are molded in poly(dimethylsiloxane) (PDMS) by soft lithography due to the favorable properties of PDMS: biocompatible, elastomeric, transparent, gas-permeable, inexpensive, and ...
  • Martínez-Mármol, Ramón; Comes, Núria; Styrczewska, Katarzyna; Pérez Verdaguer, Mireia; Vicente García, Rubén, 1978-; Pujadas, Lluís; Soriano, Eduardo; Sorkin, Alexander; Felipe, Antonio (Springer, 2016)
    The potassium channel Kv1.3 plays roles in immunity, neuronal development and sensory discrimination. Regulation of Kv1.3 by kinase signaling has been studied. In this context, EGF binds to specific receptors (EGFR) and ...

    Our closest living relatives, chimpanzees and bonobos, have a complex demographic history. We analyzed the high-coverage whole genomes of 75 wild-born chimpanzees and bonobos from 10 countries in Africa. We found that ...
  • Lazaridis, Iosif; Comas, David, 1969-; Reich, David (2016)
    We report genome-wide ancient DNA from 44 ancient Near Easterners ranging in time between ~12,000 and 1,400 bc, from Natufian hunter-gatherers to Bronze Age farmers. We show that the earliest populations of the Near East ...
