Diffusion Maps for dimensionality reduction and visualization of meteorological data

This is the author’s version of a work that was accepted for publication in Neurocomputing. Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication. A definitive version was subsequently published in Neurocomputing, VOL 163, (2015) DOI 10.1016/j.neucom.2014.08.090The growing interest in big data problems implies the need for unsupervised methods for data visualization and dimensionality reduction. Diffusion Maps (DM) is a recent technique that can capture the lower dimensional geometric structure underlying the sample patterns in a way which can be made to be independent of the sampling distribution. Moreover, DM allows us to define an embedding whose Euclidean metric relates to the sample's intrinsic one which, in turn, enables a principled application of k-means clustering. In this work we give a self-contained review of DM and discuss two methods to compute the DM embedding coordinates to new out-of-sample data. Then, we will apply them on two meteorological data problems that involve time and spatial compression of numerical weather forecasts and show how DM is capable to, first, greatly reduce the initial dimension while still capturing relevant information in the original data and, also, how the sample-derived DM embedding coordinates can be extended to new patterns.The authors acknowledge partial support from Spain's grant TIN2010-21575-C02-01 and the UAM{ADIC Chair for Machine Learning.

Una propuesta expositiva de la habitabilidad contemporánea y sus escenarios

El carácter de laboratorio urbano y habitacional adquirido por el ámbito doméstico en las últimas décadas, así como la tendencia contemporánea a la exteriorización virtual de la cotidianeidad, han hecho del ciberespacio un soporte a través del cual es posible explicitar el universo de la habitabilidad contemporánea empleando el propio habitar-como-existencia como dispositivo de análisis. De este modo, significados implícitos a los objetos, descripciones de estancias, comportamientos, etc.; son perceptibles hoy fundamentalmente a través de imágenes transferidas diariamente y a tiempo real por sus propios autores, constituyendo un vasto archivo documental sobre el habitar. La existencia de tal archivo supone una importante transformación para el estudio de la habitabilidad contemporánea y para la Arquitectura, pues las combinaciones e interferencias entre historias habitacionales particulares que antes sólo acontecían en el espacio físico diseñado por esta última, ahora empiezan a tener lugar en el espacio virtual, de acuerdo a nuevos patrones de funcionamiento; y haciéndose accesible e implicando en el estudio de la habitabilidad contemporánea, a todo individuo preocupado por auto-gestionar su habitar. Pero, ¿Cómo hacer partícipe a la sociedad de que tal hecho está aconteciendo en el ciberespacio?; ¿Cómo hacerle llegar a un común más amplio la necesidad de gestionar el propio habitar?; ¿Cómo hacer entender que es precisamente la pasividad promovida por el Espectáculo y el Mercado lo que ha hecho de los modos de vida contemporáneos una de las causas que nos sumerge en el estado de conmoción mundial (tanto a nivel económico, como social y medioambiental) en que nos encontramos? A pesar de que estas circunstancias estén dándose hoy en el ciberespacio y de que en él sea posible encontrar ensayos ya practicados por individuos que han decidido crear ellos mismos sus propias historias habitacionales, los mecanismos de transferencia de todo ello a la sociedad siguen pendientes de revisión. Por tal motivo, la intención fundamental de esta tesis consiste en generar un documento de vocación pedagógica que indague en la viabilidad del estudio de la habitabilidad contemporánea en torno al aprendizaje de redes, para de este modo, plantear sistemas de orientación en tal análisis, que den las claves sobre cómo transferir y transparentar la posibilidad de un habitar alternativo, perceptible en el soporte digital, a un soporte físico constituido por un territorio próximo. Para ello, se extraerán de los ejemplos proporcionados por la red, en concreto del habitar de individuos creativos contemporáneos, otras posibilidades de relación con los diversos factores que interfieren en el habitar y que dan pie a modos de vida situados al margen de los prototipos establecidos por el Mercado y la Sociedad del Espectáculo. Se trata en definitiva, de tejer hilos capaces de transferir lo que está aconteciendo en el escenario 2.0, a estos otros escenarios que habitamos cotidianamente, a nuestros escenarios 1.0, a nuestras historias domésticas, a lo que cada individuo es capaz de controlar desde su propio habitar. Pues sólo desde la propia implicación seremos capaces de definir los escenarios que hoy necesitamos

Assessing a fleet of robots for herbicide applications

Advanced technologies are critical for safe, site-specific and efficient control of pests (weeds, pathogens and insects) in agricultural crops. Although the scientific and technological bases of precision crop protection are mostly known and robust, the commercial application of these new technologies is still very limited. To overcome this situation, new farming methods and processes should be designed. Modern approaches rely on existing information and communication technologies (ICT) and design and construction of improved pest and crop sensors, along with enhanced pest control actuators. Mobile platforms are essential to move the needed sensors and actuators throughout the work field. Moreover, by using autonomous mobile platforms equipped with innovative perception techniques, data processing systems and tools for action, pest control procedures can be applied only if, when and where they are needed, reducing costs, environmental damages and risks for farmers. This article describes the RHEA fleet of robots highlighting the concepts and analyzing the results achieved on the application of herbicide on wheat with a spray boom.This project is funded in part by the 7th Framework Programme of the European Union under Grant Agreement No. 245986.Peer Reviewe

Comprehensive characterization of industrial wastewaters using EEM fluorescence, FT-IR and 1H NMR techniques

The organic matter present in six industrial wastewaters (pulp and paper mill, brewery, textile, dairy, slaughterhouse effluents and a municipal landfill leachate) has been studied in this work using three analytical techniques: excitation-emission matrix fluorescence (EEMF), proton nuclear magnetic resonance spectroscopy (1H NMR) and Fourier transform infrared spectroscopy (FTIR). The pulp and paper mill effluent shows characteristic signals of the presence of lignins, carbohydrates and carboxylic acids, as well as sulfate, carbonate and sulfonates (coming from surfactants used in the cleaning of tanks). The main constituents of the brewery effluent are peptides and proteins coming mainly from spent yeast and diatomite filters (the presence of the latter was confirmed by Sisingle bondO bands in the FTIR spectrum). The municipal landfill leachate is characterized by the majority presence of humic substances (typical of an old landfill) and a residual presence of small peptides, amino acids and carboxylic acids. Additionally, several inorganic compounds were identified by FTIR, such as nitrate, sulfate, phosphate and cyanide ions. The textile effluent from a cotton-based industry contains carbohydrates, carboxylic acids and sulfonates, which can act as auxochromes in the textile industry. The dairy effluent comprises amino acids and small peptides coming from the biodegradation of milk and whey in addition to carbohydrates (lactose) and carboxylic acids (mainly lactic acid). The presence of tyrosine-like peaks B in the EEMF spectrum of the slaughterhouse effluent indicates the existence of small peptides and amino acids coming from the biodegradation of blood proteins. Additionally, residual glucose, fatty acids, phosphate and sulfate were also identified in this effluent

Spectral response of dielectric nano-antennas in the far- and near-field regimes

Recent studies show that the spectral behaviour of localized surface plasmon resonances (LPSRs) in metallic nanoparticles su er from both a redshift and a broadening in the transition from the far- to the near-field regimes. An interpretation of this efect was given in terms of the evanescent and propagating components of the angular spectrum representation of the radiated eld. Due to the increasing interest awakened by magnetodielectric materials as a both low-loss material option for nanotechnology applications, and also for their particular scattering properties, here we study the spectral response of a magnetodielectric nanoparticle as a basic element of a dielectric nano-antenna. This study is made by analyzing the changes su ered by the scattered electromagnetic field when propagating from the surface of this dielectric nanostructure to the far-zone in terms of propagating and evanescent plane wave components of the radiated fields.This research was supported by MICINN (Spanish Ministry of Science and Innovation) with project FIS2013- 45854-P

eHealth and mHealth development in Spain: promise or reality?

In the last decades, the use of Information and Communication Technologies (ICTs) has progressively spread to society and public administration. Health is one of the areas in which the use of ICTs has more intensively developed through what is now known as eHealth. That area has recently included mHealth. Spanish health system has stood out as one of the benchmarks of this technological revolution. The development of ICTs applied to health, especially since the outbreak of the pandemic caused by SARS Cov-2, has increased the range of health services delivered through smartphones and the development of subsequent specialized apps. Based on the data of a Survey on Use and Attitudes regarding eHealth in Spain, the aim of this research was to conduct a comparative analysis of the different eHealth and mHealth user profiles. The results show that the user profile of eHealth an mHealth services in Spain is not in a majority. Weaknesses are detected both in the knowledge and use of eHealth services among the general population and in the usability or development of their mobile version. Smartphones can be a democratizing vector, as for now, access to eHealth services is only available to wealthy people, widening inequality.Ministerio de Economía y Competitividad | Ref.

Comparative Analysis of Muscle Transcriptome between Pig Genotypes Identifies Genes and Regulatory Mechanisms Associated to Growth, Fatness and Metabolism.

Iberian ham production includes both purebred (IB) and Duroc-crossbred (IBxDU) Iberian pigs, which show important differences in meat quality and production traits, such as muscle growth and fatness. This experiment was conducted to investigate gene expression differences, transcriptional regulation and genetic polymorphisms that could be associated with the observed phenotypic differences between IB and IBxDU pigs. Nine IB and 10 IBxDU pigs were slaughtered at birth. Morphometric measures and blood samples were obtained and samples from Biceps femoris muscle were employed for compositional and transcriptome analysis by RNA-Seq technology. Phenotypic differences were evident at this early age, including greater body size and weight in IBxDU and greater Biceps femoris intramuscular fat and plasma cholesterol content in IB newborns. We detected 149 differentially expressed genes between IB and IBxDU neonates (p < 0.01 and Fold-Change > 1. 5). Several were related to adipose and muscle tissues development (DLK1, FGF21 or UBC). The functional interpretation of the transcriptomic differences revealed enrichment of functions and pathways related to lipid metabolism in IB and to cellular and muscle growth in IBxDU pigs. Protein catabolism, cholesterol biosynthesis and immune system were functions enriched in both genotypes. We identified transcription factors potentially affecting the observed gene expression differences. Some of them have known functions on adipogenesis (CEBPA, EGRs), lipid metabolism (PPARGC1B) and myogenesis (FOXOs, MEF2D, MYOD1), which suggest a key role in the meat quality differences existing between IB and IBxDU hams. We also identified several polymorphisms showing differential segregation between IB and IBxDU pigs. Among them, non-synonymous variants were detected in several transcription factors as PPARGC1B and TRIM63 genes, which could be associated to altered gene function. Taken together, these results provide information about candidate genes, metabolic pathways and genetic polymorphisms potentially involved in phenotypic differences between IB and IBxDU pigs associated to meat quality and production traits
