An Introductory Review of a Structural VAR-X Estimation and Applications

This document presents how to estimate and implement a structural VAR-X model under long run and impact identification restrictions. Estimation by bayesian and maximum likelihood methods is presented. Applications of the structural VAR-X for impulse response functions to structural shocks, multiplier analysis of the exogenous variables, forecast error variance decomposition and historical decomposition of the endogenous variables are also described, as well as a method for computing HPD regions in a bayesian context. Some of the concepts are exemplified with an application to US data.S-VAR, B-VAR, VAR-X, IRF, FEVD, Historical Decomposition. Classification JEL: C11, C18, C32.

Boosting terminology extraction through crosslingual resources

Terminology Extraction is an important Natural Language Processing task with multiple applications in many areas. The task has been approached from different points of view using different techniques. Language and domain independent systems have been proposed as well. Our contribution in this paper focuses on the improvements on Terminology Extraction using crosslingual resources and specifically the Wikipedia and on the use of a variant of PageRank for scoring the candidate terms. // La extracción de terminología es una tarea de procesamiento de la lengua sumamente importante y aplicable en numerosas áreas. La tarea se ha abordado desde múltiples perspectivas y utilizando técnicas diversas. También se han propuesto sistemas independientes de la lengua y del dominio.

Genome scale metabolic modeling reveals the metabolic potential of three Type II methanotrophs of the genus Methylocystis

Producción CientíficaGenome Scale Metabolic Models (GSMMs) of the recently sequenced Methylocystis hirsuta and two other methanotrophs from the genus Methylocystis have been reconstructed. These organisms are Type II methanotrophs with the ability of accumulating Polyhydroxyalkanoates under nutrient limiting conditions. For the first time, GSMMs have been reconstructed for Type II methanotrophs. These models, combined with experimental biomass and PHB yields of Methylocystis hirsuta, allowed elucidating the methane oxidation mechanism by the enzyme pMMO (particulate methane monooxygenase) in these organisms. In contrast to Type I methanotrophs, which use the “direct coupling mechanism”, Type II methanotrophs appear to use the so called “redox arm mechanism”. The utilization of the “redox arm mechanism”, which involves the coupling between methane oxidation and complex I of the respiratory chain, was confirmed by inhibition of complex I with catechol. Utilization of the “redox arm” mechanism leads to lower biomass yields on methane compared to Type I methanotrophs. However, the ability of Type II methanotrophs to redirect high metabolic carbon fluxes towards acetoacetyl-CoA under nitrogen limiting conditions makes these organisms promising platforms for metabolic engineering.Marie Curie grant H2020-MSCA-IF-2016 CH4BioVal (GA nº 750126).Junta de Castilla y León (Ref.

Trends in the design and use of elastin-like recombinamers as biomaterials

Producción CientíficaElastin-like recombinamers (ELRs), which derive from one of the repetitive domains found in natural elastin, have been intensively studied in the last few years from several points of view. In this mini review, we discuss all the recent works related to the investigation of ELRs, starting with those that define these polypeptides as model intrinsically disordered proteins or regions (IDPs or IDRs) and its relevance for some biomedical applications. Furthermore, we summarize the current knowledge on the development of drug, vaccine and gene delivery systems based on ELRs, while also emphasizing the use of ELR-based hydrogels in tissue engineering and regenerative medicine (TERM). Finally, we show different studies that explore applications in other fields, and several examples that describe biomaterial blends in which ELRs have a key role. This review aims to give an overview of the recent advances regarding ELRs and to encourage further investigation of their properties and applications.Comisión Europea (project NMP-2014-646075)Ministerio de Economía, Industria y Competitividad (projects PCIN-2015-010 / MAT2016-78903-R / BES-2014-069763)Junta de Castilla y León (project VA317P18

WMT 2016 Multimodal translation system description based on bidirectional recurrent neural networks with double-embeddings

Bidirectional Recurrent Neural Networks (BiRNNs) have shown outstanding results on sequence-to-sequence learning tasks. This architecture becomes specially interesting for multimodal machine translation task, since BiRNNs can deal with images and text. On most translation systems the same word embedding is fed to both BiRNN units. In this paper, we present several experiments to enhance a baseline sequence-to-sequence system (Elliott et al., 2015), for example, by using double embeddings. These embeddings are trained on the forward and backward direction of the input sequence. Our system is trained, validated and tested on the Multi30K dataset (Elliott et al., 2016) in the context of theWMT 2016Multimodal Translation Task. The obtained results show that thedouble-embedding approach performs significantly better than the traditional single-embedding one.Postprint (published version

Actividades sobre Inteligencias Múltiples enfocadas al alumnado y aplicación práctica en el aula de Inglés en Educación Primaria

Este trabajo es un estudio basado en una propuesta didáctica. Lleva a cabo una experiencia en un aula de inglés de 2º de educación primaria con la finalidad de mostrar y abordar la teoría de las inteligencias múltiples desde una perspectiva diferente. Nuestra finalidad en este estudio no es mostrar esta teoría como un recurso para el profesorado sino que se pretende mostrársela al alumnado como un medio para que se conozcan mejor a sí mismos y comprendan que existen diferentes maneras de aprender. No obstante, también existen objetivos en este proyecto relacionados con los resultados de las actividades que se realizan durante las sesiones llevadas a la práctica. Estos objetivos entran en el orden de secundarios ya que el número de sesiones es muy reducido y su evaluación necesita un trabajo más exhaustivo para ser precisa.Grado en Educación Primari
