• Retractions onto series-parallel posets

  Dalmau, Víctor; Krokhin, Andrei; Larose, Benoit (Elsevier, 2008)

  The poset retraction problem for a poset P is whether a given poset Q containing P as a subposet admits a retraction onto P, that is, whether there is a homomorphism from Q onto P which fixes every element of P. We study ...
• Majority constraints have bounded pathwidth duality

  Dalmau, Víctor; Krokhin, Andrei (Elsevier, 2008)

  We study certain constraint satisfaction problems which are the problems of deciding whether there exists a homomorphism from a given relational structure to a fixed structure with a majority polymorphism. We show that ...
• On the overlap between bilingual language control and domain-general executive control

  Branzi, Francesca Martina, 1984-; Calabria, Marco; Boscarino, Maria Lucrezia; Costa, Albert (Elsevier, 2016)

  We explored the overlap between bilingual language control (bLC) and domain-general executive control (EC) by focusing on inhibitory control processes. We tested 62 bilinguals in linguistic and non-linguistic switching ...
• Competing engines of growth: innovation and standardization

  Acemoglu, Daron; Gancia, Gino; Zilibotti, Fabrizio (Elsevier, 2010)

  We study a dynamic general equilibrium model where innovation takes the form of the introduction of new goods whose production requires skilled workers. Innovation is followed by a costly process of standardization, where ...
• Why do emerging economies borrow short term?

  Broner, Fernando; Lorenzoni, Guido; Schumkler, Sergio L. (Wiley, 2013)

  We argue that one reason why emerging economies borrow short term is that it is cheaper than borrowing long term. This is especially the case during crises, as in these episodes the relative cost of long-term borrowing ...
• Las dimensiones sociales de la percepción de la energía nuclear. Un análisis del caso español (1960-2015)

  Espluga Trenc, Josep; Medina, Beatriz; Presas, Albert; Rubio-Varas, Mar; De la Torre, Joseba (Consejo Superior de Investigaciones Científicas, 2017)

  La energía nuclear es una tecnología compleja, que requiere un uso muy intensivo de recursos y una toma de decisiones muy centralizada, cuya gobernanza supone un auténtico reto para las sociedades democráticas. En el ...
• The Micro origins of international business-cycle comovement

  Di Giovanni, Julian; Levchenko, Andrei A.; Mejean, Isabelle (American Economic Association, 2018)

  This paper investigates the role of individual firms in international business-cycle comovement using data covering the universe of French firm-level value added and international linkages over the period 1993–2007. At the ...
• Grounding semantic roles in images

  Silberer, Carina; Pinkal, Manfred (ACL (Association for Computational Linguistics), 2018)

  We address the task of visual semantic role labeling (vSRL), the identification of the participants of a situation or event in a visual scene, and their labeling with their semantic relations to the event or situation. We ...
• Rising declaratives of the quality-suspending kind

  Westera, Matthijs (Ubiquity Press, 2018)

  The theory of Intonational Compliance Marking (ICM) maintains that speakers of English use final rising intonation to indicate a suspension (potential violation) of a conversational maxim (Westera 2013; 2014). This paper ...
• Survey on automatic lip-reading in the era of deep learning

  Fernandez-Lopez, Adriana; Sukno, Federico Mateo (Elsevier, 2018)

  In the last few years, there has been an increasing interest in developing systems for Automatic Lip-Reading (ALR). Similarly to other computer vision applications, methods based on Deep Learning (DL) have become very ...
• Applying dependency relations to definition extraction

  Espinosa-Anke, Luis; Saggion, Horacio (Springer, 2014)

  Definition Extraction (DE) is the task to automatically identify definitional knowledge in naturally-occurring text. This task has applications in ontology generation, glossary creation or question answering. Although the ...
• Corpus-based sentence deletion and split decisions for Spanish text simplification

  Stajner, Sanja; Drndarevic, Biljana; Saggion, Horacio (2013)

  This study addresses the automatic simplification of texts in Spanish in order to make them more accessible to people with cognitive disabilities. A corpus analysis of original and manually simplified news articles was ...
• Finding and expanding hypernymic relations in the music domain

  Espinosa-Anke, Luis; Oramas, Sergio; Camacho-Collados, Jose; Saggion, Horacio (2016)

  Lexical taxonomies are tree or directed acyclic graph-like structures where each node represents a concept and each edge encodes a binary hypernymic (is-a) relation. These lexical resources are useful for AI tasks like ...
• Relation between circulating CC16 concentrations, lung function, and development of chronic obstructive pulmonary disease across the lifespan: a prospective study

  Guerra, Stefano; Halonen, Marilyn; Vasquez, Monica M.; Spangenberg, Amber; Stern, Debra A.; Morgan, Wayne J.; Wright, Anne L.; Carsin, Anne-Elie; Dobaño, Carlota; Barreiro Portela, Esther; Zock, Jan-Paul; Martínez-Moratalla, Jesús; Sunyer Deu, Jordi; Antó i Boqué, Josep Maria; Martinez, Fernando D. (Elsevier, 2015)

  BACKGROUND: Low concentrations of the anti-inflammatory protein CC16 (approved symbol SCGB1A1) in serum have been associated with accelerated decline in forced expiratory volume in 1 s (FEV1) in patients with chronic ...
• Promoter architecture determines cotranslational regulation of mRNA

  Espinar, Lorena; Schikora Tamarit, Miquel Àngel; Domingo, Júlia; Carey, Lucas, 1980- (Cold Spring Harbor Laboratory Press (CSHL Press), 2018)

  Information that regulates gene expression is encoded throughout each gene but if different regulatory regions can be understood in isolation, or if they interact, is unknown. Here we measure mRNA levels for 10,000 open ...
• The urban exposome during pregnancy and its socioeconomic determinants

  Robinson, Oriol; Tamayo-Uria, Ibon; de Castro, Montserrat; Valentín, Antònia; Ambros, Albert; Cirach, Marta; Donaire González, David; Maitre, Léa; Sunyer Deu, Jordi; Urquiza, José M.; Vrijheid, Martine; Nieuwenhuijsen, Mark J.; Basagaña Flores, Xavier (National Institute of Environmental Health Sciences, 2018)

  Background: The urban exposome is the set of environmental factors that are experienced in the outdoor urban environment and that may influence child development. Objective: The authors’ goal was to describe the urban ...
• On categorizing types of role shift in sign languages

  Quer, Josep, 1965- (De Gruyter, 2018)

  Role shift is the widespread phenomenon in sign languages whereby a signer reports utterances, thoughts or actions of a character in another context by resorting to a possibly very rich array of nonmanual markers that ...
• Extremes of error exponents

  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 ...
• Mismatched decoding: error exponents, second-order rates and saddlepoint approximations

  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 ...
