A Microarray study of Carpet-Shell Clam (Ruditapes decussatus) shows common and organ-specific growth-related gene expression Differences in gills and digestive gland
Growth rate is one of the most important traits from the point of view of individual fitness and commercial production in mollusks, but its molecular and physiological basis is poorly known. We have studied differential gene expression related to differences in growth rate in adult individuals of the commercial marine clam Ruditapes decussatus. Gene expression in the gills and the digestive gland was analyzed in 5 fast-growing and five slow-growing animals by means of an oligonucleotide microarray containing 14,003 probes. A total of 356 differentially expressed genes (DEG) were found. We tested the hypothesis that differential expression might be concentrated at the growth control gene core (GCGC), i. e., the set of genes that underlie the molecular mechanisms of genetic control of tissue and organ growth and body size, as demonstrated in model organisms. The GCGC includes the genes coding for enzymes of the insulin/ insulin-like growth factor signaling pathway (IIS), enzymes of four additional signaling pathways (Raf/ Ras/ Mapk, Jnk, TOR, and Hippo), and transcription factors acting at the end of those pathways. Only two out of 97 GCGC genes present in themicroarray showed differential expression, indicating a very little contribution of GCGC genes to growth-related differential gene expression. Forty eight DEGs were shared by both organs, with gene ontology (GO) annotations corresponding to transcription regulation, RNA splicing, sugar metabolism, protein catabolism, immunity, defense against pathogens, and fatty acid biosynthesis. GO termenrichment tests indicated that genes related to growth regulation, development and morphogenesis, extracellular matrix proteins, and proteolysis were overrepresented in the gills. In the digestive gland overrepresented GO terms referred to gene expression control through chromatin rearrangement, RAS-related small GTPases, glucolysis, and energy metabolism. These analyses suggest a relevant role of, among others, some genes related to the IIS, such as the ParaHox gene Xlox, CCAR and the CCN family of secreted proteins, in the regulation of growth in bivalves.Direccion General de Investigacion Cientifica y Tecnica of the Spanish Government [AGL2010-16743, AGL2013-49144-C3-3-R]; COMPETE Program; Portuguese National Funds [PEst-255 C/MAR/LA0015/2011]; Portuguese FCT [UID/Multi/04326/2013]; Generalitat Valenciana; Ministry of Education, Culture, and Sports of the Spanish Government; Association of European Marine Biology Laboratoriesinfo:eu-repo/semantics/publishedVersio
A scalable saliency-based Feature selection method with instance level information
Classic feature selection techniques remove those features that are either
irrelevant or redundant, achieving a subset of relevant features that help to
provide a better knowledge extraction. This allows the creation of compact
models that are easier to interpret. Most of these techniques work over the
whole dataset, but they are unable to provide the user with successful
information when only instance information is needed. In short, given any
example, classic feature selection algorithms do not give any information about
which the most relevant information is, regarding this sample. This work aims
to overcome this handicap by developing a novel feature selection method,
called Saliency-based Feature Selection (SFS), based in deep-learning saliency
techniques. Our experimental results will prove that this algorithm can be
successfully used not only in Neural Networks, but also under any given
architecture trained by using Gradient Descent techniques

Las identidades de la religión castreña: propuesta de estudio
El presente texto deriva del trabajo de fin de máster Religión e identidad en el Noroeste peninsular prerromano: un ensayo de aproximación dirigido por Eduardo Sánchez Moreno, en el Máster Interuniversitario de Historia y Ciencias de la Antigüedad, presentado durante el curso académico 2012-2013El presente artículo tiene como objetivo ofrecer un modelo de compresión de las manifestaciones religiosas del Noroeste peninsular prerromano del Hierro Final, de acuerdo con sus posibles funciones para las diferentes sociedades castreñas. Se pretende ilustrar cómo la relación entre ciertos esquemas ideológicos y manifestaciones sociales puede ser entendida a través de los procesos de construcción de diversos tipos de identidades y de reformulación de la memoria cultural castreña. Y, de este modo, lograr una comprensión más exhaustiva y completa de la religión de esta cultura mediante la cual, quizás, integrar los datos que conservamos dispersos sobre la mismaThis article aims to provide a model in order to understand religious manifestations of the pre-Roman peninsular North-West area in the late Iron Age, according to their possible functions for different hillfort societies. It is intended to illustrate how the relationship between certain ideological schemes and social events can be understood through the processes of construction of several types of identities and the reshaping of the hillfort cultural memory. Thus, the focus of this article is to achieve a more thorough and comprehensive understanding of the hillfort religion, which might help to integrate the scattered data preserve
Gobiernos y Parlamento en las Cortes de Cádiz y de Isabel II
GOBIERNOS Y PARLAMENTO EN LAS CORTES DE CÁDIZ Y DE ISABEL II.
Pretendemos explicar el funcionamiento de las Cortes de Cádiz y los problemas políticos que generó la confusa relación entre los poderes ejecutivo y legislativo en la primera constitución española. En segundo lugar, analizaremos cómo se va articulando bajo la monarquía de Isabel II un incipiente régimen parlamentario. Un proceso obstaculizado por la deriva autoritaria del Ejecutivo en algunos momentos, por la injerencia de la Corona en la formación de los gobiernos y la devaluación de las Cortes por la debilidad de los partidos de "notables" que se alternaban en el Poder. Tres factores que dificultaron gravemente la evolución a una efectiva monarquía parlamentaria".Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
