Este proyecto se centra en la parte de extracción de imágenes a un Frame Rate adecuado a nuestras necesidades con el consecuente estudio de las diferentes posibilidades actuales en el mercado, y su posterior procesado 3D. Así mismo, también se estudian todas las posibles características extraíbles desde modelos 2D y 3D

Analytical and Numerical Methods for Differential Equations and Applications

This research topic shows the large amount of different types of differential equations, thus it contains a selection of papers with recent advances in subjects as different as delay differential equations, nonlinear partial differential equations (PDEs), studied analytically or numerically, or because of their applications, fractional PDEs, and q-differential equations, etc. We would like to thank all the contributors of this issue, and also the referees. They all worked hard to shed some light on these topics for young researchers who would like to investigate some of these areas. Thus, in this research topic, readers can find papers on varying numerical methods and applications

Diagnóstico geográfico del riesgo de degradación residencial

El objetivo principal del estudio es determinar de qué manera se podía identificar la presencia de riesgo de degradación residencial (RDR) en un área urbana. La hipótesis de partida consiste en la afirmación de que es posible hacer esta identificación a través de la información del Censo y del Catastro, dos bases de datos fácilmente disponibles. La metodología utilizada en el desarrollo de este estudio se basa en el uso del método cuantitativo, mediante el análisis de los datos mencionados por el método de evaluación multivariante que permite establecer el peso relativo de cada uno de los indicadores previamente elaborado con respecto al conjunto. La ponderación de las dos principales agrupaciones de datos (referentes a los edificios y a la caracterización socioeconómica de sus habitantes) utilizadas y su análisis mediante este método han permitido esclarecer la importancia de cada uno de ellos para la caracterización de las parcelas que deban contar con actuaciones prioritarias de reforma urbana. Los datos obtenidos de la ponderación de indicadores se representan con la ayuda de sistemas de información geográfica obteniendo así unos mapas en los cuales se diagnostica el riesgo de degradación residencial. Los resultados se contrastan y depuran mediante visita de campo.Peer Reviewe

Bioactive Peptides from Algae: Traditional and Novel Generation Strategies, Structure-Function Relationships, and Bioinformatics as Predictive Tools for Bioactivity

Over the last decade, algae have been explored as alternative and sustainable protein sources for a balanced diet and more recently, as a potential source of algal-derived bioactive peptides with potential health benefits. This review will focus on the emerging processes for the generation and isolation of bioactive peptides or cryptides from algae, including: (1) pre-treatments of algae for the extraction of protein by physical and biochemical methods; and (2) methods for the generation of bioactive including enzymatic hydrolysis and other emerging methods. To date, the main biological properties of the peptides identified from algae, including anti-hypertensive, antioxidant and antiproliferative/ cytotoxic effects (for this review, anti-proliferative/cytotoxic will be referred to by the term anti-cancer), assayed in vitro and/or in vivo, will also be summarized emphasizing the structure–function relationship and mechanism of action of these peptides. Moreover, the use of in silico methods, such as quantitative structural activity relationships (QSAR) and molecular docking for the identification of specific peptides of bioactive interest from hydrolysates will be described in detail together with the main challenges and opportunities to exploit algae as a source of bioactive peptides

Housing prices and credit constraints in competitive search

We embed a competitive search model of the real estate market into a heterogeneous agentsetting where hoeholds face credit constraints and idiosyncratic turnover shocks. Householdscan accumulate a risk-free asset to build a down payment and to smooth non-housing consumption.There is an inelastic supply of identical homes. The model is "block recursive". Inequilibrium wealthier home buyers sort into submarkets with higher prices and shorter buyingtimes. We identify a novel amplification mechanism, arising from sorting, by which demandshocks can substantially affect housing prices. In particular, lowering down payment requirementsinduces entry of new buyers in the market and higher asset accumulation by currentsearchers, as these agents target more expensive (less congested) submarkets. This affects thedistribution of prices and trading probabilities, and thereby the wealth distribution. Our quantitativeresults suggest that the effects on the long-run level and dispersion of housing pricescan be significant.Support from the Spanish Ministerio Economía y Competitividad, grants ECO2016-76818-C3-1-P and ECO2017-86261-P, MDM 2014-0431, and Comunidad de Madrid, MadEco-CM (S2015/HUM-3444), is gratefully acknowledged

Enhancing the Extraction of Polysaccharides and Antioxidants from Macroalgae Using Sequential Hydrothermal-Assisted Extraction Followed by Ultrasound and Thermal Technologies

peer-reviewedFucose sulphated polysaccharides (FSPs) and glucans have recently attracted the attention of the scientific community due to their wide range of biological activities. Both polysaccharides should ideally be selectively extracted using innovative technologies with high extraction efficiency. This study aims to: (1) Optimise the extraction variables used in hydrothermal-assisted extraction (HAE) to obtain high yields of FSPs, total glucans, and antioxidants from Laminaria hyperborea; (2) to apply these optimised protocols to other brown macroalgae; and (3) to explore the application of ultrasound and thermal technologies to increase the recovery of polysaccharides from the residual biomass. Box-Behnken design (three-factor, four-levels) was employed to optimise the HAE variables, and principal component analysis was used to evaluate the recovery of polysaccharides from the residual biomass. The optimal HAE conditions were 120 °C, 80.9 min, and 12.02 mL/g macroalgae from L. hyperborea. The best sequential application of ultrasound and thermal treatment achieved an additional 2971.7 ± 61.9 mg fucose/100 g dried macroalgal residue (dmr) from Ascophyllum nodosum and 908.0 ± 51.4 mg total glucans/100 g dmr from L. hyperborea macroalgal residues

Recovery of early meteorological records from Extremadura region (SW Iberia): The ''CliPastExtrem'' (v1.0) database

In this work, we provide instrumental meteorological data recovered for the Extremadura region (interior SW Iberia), from 1826 to mid-20th century. Meteorological variables such as air temperature, atmospheric pressure, precipitation, wind direction and humidity, among others, were retrieved. In total, more than 750 000 instrumental data in 157 meteorological series belonging to 131 different locations throughout Extremadura were rescued. It must be noted that daily resolution data constitutes 80% of the database. This great effort of digitization and data collection has been carried out with the aim of contributing to a significant expansion of the length of the databases with meteorological information in this region. Therefore, this database will provide a better understanding of climate variability, trends and extreme events of the Extremadura region
