Energy Efficiency of Hybrid-Power HetNets: A Population-like Games Approach

In this paper, a distributed control scheme based on population games is proposed. The controller is in charge of dealing with the energy consumption problem in a Heterogeneous Cellular Network (HetNet) powered by hybrid energy sources (grid and renewable energy) while guaranteeing appropriate quality of service (QoS) level at the same time. Unlike the conventional approach in population games, it considers both atomicity and non-anonymity. Simulation results show that the proposed population-games approach reduces grid consumption by up to about 12% compared to the traditional best-signal level association policy.U.S. Air Force Office of Scientific Research FA9550-17-1-0259Ministerio de Cultura y Deporte DPI2016-76493-C3-3-RMinisterio de Economía y Empresa DPI2017-86918-

Computer vision techniques for forest fire perception

This paper presents computer vision techniques for forest fire perception involving measurement of forest fire properties (fire front, flame height, flame inclination angle, fire base width) required for the implementation of advanced forest fire-fighting strategies. The system computes a 3D perception model of the fire and could also be used for visualizing the fire evolution in remote computer systems. The presented system integrates the processing of images from visual and infrared cameras. It applies sensor fusion techniques involving also telemetry sensors, and GPS. The paper also includes some results of forest fire experiments.European Commission EVG1-CT-2001-00043European Commission IST-2001-34304Ministerio de Educación y Ciencia DPI2005-0229

The Conformational Stability and Biophysical Properties of the Eukaryotic Thioredoxins of Pisum Sativum Are Not Family-Conserved

Thioredoxins (TRXs) are ubiquitous proteins involved in redox processes. About forty genes encode TRX or TRX-related proteins in plants, grouped in different families according to their subcellular localization. For instance, the h-type TRXs are located in cytoplasm or mitochondria, whereas f-type TRXs have a plastidial origin, although both types of proteins have an eukaryotic origin as opposed to other TRXs. Herein, we study the conformational and the biophysical features of TRXh1, TRXh2 and TRXf from Pisum sativum. The modelled structures of the three proteins show the well-known TRX fold. While sharing similar pH-denaturations features, the chemical and thermal stabilities are different, being PsTRXh1 (Pisum sativum thioredoxin h1) the most stable isoform; moreover, the three proteins follow a three-state denaturation model, during the chemical-denaturations. These differences in the thermal- and chemical-denaturations result from changes, in a broad sense, of the several ASAs (accessible surface areas) of the proteins. Thus, although a strong relationship can be found between the primary amino acid sequence and the structure among TRXs, that between the residue sequence and the conformational stability and biophysical properties is not. We discuss how these differences in the biophysical properties of TRXs determine their unique functions in pea, and we show how residues involved in the biophysical features described (pH-titrations, dimerizations and chemical-denaturations) belong to regions involved in interaction with other proteins. Our results suggest that the sequence demands of protein-protein function are relatively rigid, with different protein-binding pockets (some in common) for each of the three proteins, but the demands of structure and conformational stability per se (as long as there is a maintained core), are less so

APPRIS principal isoforms and MANE Select transcripts define reference splice variants.

Selecting the splice variant that best represents a coding gene is a crucial first step in many experimental analyses, and vital for mapping clinically relevant variants. This study compares the longest isoforms, MANE Select transcripts, APPRIS principal isoforms, and expression data, and aims to determine which method is best for selecting biological important reference splice variants for large-scale analyses. Proteomics analyses and human genetic variation data suggest that most coding genes have a single main protein isoform. We show that APPRIS principal isoforms and MANE Select transcripts best describe these main cellular isoforms, and find that using the longest splice variant as the representative is a poor strategy. Exons unique to the longest splice isoforms are not under selective pressure, and so are unlikely to be functionally relevant. Expression data are also a poor means of selecting the main splice variant. APPRIS principal and MANE Select exons are under purifying selection, while exons specific to alternative transcripts are not. There are MANE and APPRIS representatives for almost 95% of genes, and where they agree they are particularly effective, coinciding with the main proteomics isoform for over 98.2% of genes. APPRIS principal isoforms for human, mouse and other model species can be downloaded from the APPRIS database (https://appris.bioinfo.cnio.es), GENCODE genes (https://www.gencodegenes.org/) and the Ensembl website (https://www.ensembl.org). MANE Select transcripts for the human reference set are available from the Ensembl, GENCODE and RefSeq databases (https://www.ncbi.nlm.nih.gov/refseq/). Lists of splice variants where MANE and APPRIS coincide are available from the APPRIS database.

Entanglement structure of quantum fields through local probes

We present a framework to study the entanglement structure of a quantum field theory inspired by the formalism of particle detectors in relativistic quantum information. This framework can in principle be used to faithfully capture entanglement in a QFT between arbitrary-shaped regions of spacetime without encountering UV divergences, bypassing many of the issues typically present in other approaches. Our results also establish the limits of the efficiency of entanglement harvesting, and may also be used to motivate an operational definition of entanglement between spacetime subregions in field theory.Comment: 21 pages, 7 figures.

Fully Relativistic Entanglement Harvesting

We study the protocol of entanglement harvesting when the particle detectors that harvest entanglement from the field are replaced by fully relativistic quantum field theories. We show that two localized modes of the quantum field theories are able to harvest the same amount of leading order entanglement as two non-relativistic particle detectors, thus implying that QFT probes can generally harvest more entanglement than particle detectors. These results legitimize the use of particle detectors to study entanglement harvesting regardless of their internally non-relativistic nature.Comment: 17 pages, 3 figures. RevTeX 4.

Nutritional problems perceived by pediatricians in Spanish children younger than 3 years

Introducción: Los padres son los principales responsables de la educación nutricional de sus hijos y es labor del pediatra orientar y resolver problemas al respecto. En este estudio se pretende conocer la relevancia de las cuestiones nutricionales en la consulta del pediatra y los principales problemas nutricionales percibidos en los menores de 3 años. Métodos: Estudio descriptivo, transversal en dos fases. La primera consistió en entrevistas y grupos de discusión con 30 pediatras seleccionados aleatoriamente en Madrid y Barcelona. Los resultados se utilizaron para diseñar el cuestionario online (76 preguntas relacionadas con la nutrición en niños de 0-3 años) de la siguiente fase, en la que participaron pediatras seleccionados de forma aleatoria y representativa del territorio nacional. Resultados: De 258 pediatras seleccionados, completaron el cuestionario 151, que atendían a una media de 588 pacientes/mes. Los principales problemas nutricionales percibidos hasta los 12 meses fueron las deficiencias de hierro y vitaminas y la escasa ganancia de peso, y posteriormente la ingesta excesiva de carbohidratos y lípidos y el sobrepeso. Los padres fueron considerados los actores principales en la salud nutricional de sus hijos, pero su preocupación por esta cuestión se reduce significativamente (p < 0,0001) con la edad del niño. Los aspectos considerados más importantes para obtener unos buenos hábitos alimentarios fueron la alimentación adaptada a las necesidades del niño y respetar el tiempo de sueño. El porcentaje de pacientes que recibe recomendaciones de hábitos nutricionales varió del 88% (0-6 meses) al 61% (24-36 meses). Conclusiones: A pesar de considerar la salud nutricional importante, la intervención educativa del pediatra al respecto no es óptima. Los problemas nutricionales percibidos fueron distintos según la edadIntroduction: Parents are most responsible for nutritional education of children, and pediatritians must advise and help them with their doubts. The purpose of this study was to know the relevance of nutritional topics in daily practice and the main nutritional problems perceived by pediatritians in children under 3 years of age. Methods: Descriptive, cross-sectional study performed in 2 stages. First stage consisted on discussion meetings with 30 random-selected pediatritians from Madrid and Barcelona. Results were used to design the on-line questionnaire of the second stage (76 questions related to nutrition in children under 3 years). A random and representative sample of Spanish pediatritians was selected for this stage. Results: One hundred and fifty one pediatritians, among 258 sampled, completed the questionnaire. They referred to see a mean of 588 patients/month. The main perceived nutritional problems in the first year of life were iron and vitamin deficiencies and poor weight gain. In the next months, excess in carbohydrates and lipid intake and overweight were the main problems perceived. Parents were considered the main actors regarding their children’s nutritional health, but their concern in these questions significantly reduced with children’s age (p < 0,0001). Factors considered to have the greatest relevance in the acquisition of good nutritional habits were to provide a diet adjusted for children’s requirements and to observe the appropriate sleeping hours. The proportion of children who receive nutritional counseling varied from 88% (0-6 months) to 61% (24-36 months). Conclusions: Despite of the relevance given by pediatritians, educational intervention regarding nutritional health is not ideal. Nutritional problems perceived by pediatritians varied with children’s ageEste estudio ha sido financiado por Almiron/Danone Baby Nutrition

The GRIFFIN perception dataset: Bridging the gap between flapping-wing flight and robotic perception

The development of automatic perception systems and techniques for bio-inspired flapping-wing robots is severely hampered by the high technical complexity of these platforms and the installation of onboard sensors and electronics. Besides, flapping-wing robot perception suffers from high vibration levels and abrupt movements during flight, which cause motion blur and strong changes in lighting conditions. This letter presents a perception dataset for bird-scale flapping-wing robots as a tool to help alleviate the aforementioned problems. The presented data include measurements from onboard sensors widely used in aerial robotics and suitable to deal with the perception challenges of flapping-wing robots, such as an event camera, a conventional camera, and two Inertial Measurement Units (IMUs), as well as ground truth measurements from a laser tracker or a motion capture system. A total of 21 datasets of different types of flights were collected in three different scenarios (one indoor and two outdoor). To the best of the authors' knowledge this is the first dataset for flapping-wing robot perceptionConsejo Europeo de Investigación 788247ARM-EXTEND DPI2017-8979-
