Statistical Analysis of the Main Configuration Parameters of the Network Dynamic and Adaptive Radio Protocol (DARP)

The present work analyses the wireless sensor network protocol (DARP) and the impact of different configuration parameter sets on its performance. Different scenarios have been considered, in order to gain a better understanding of the influence of the configuration on network protocols. The developed statistical analysis is based on the method known as Analysis of Variance (ANOVA), which focuses on the effect of the configuration on the performance of DARP. Three main dependent variables were considered: number of control messages sent during the set-up time, energy consumption and convergence time. A total of 20,413 simulations were carried out to ensure greater robustness in the statistical conclusions. The main goal of this work is to discover the most critical configuration parameters for the protocol, with a view to potential applications in Smart City type scenarios.This work was partially supported by project TIN2015-71873-R (MINECO/FEDER) and TIN2015-67020-P (Spanish “Ministerio de Economía y Competitividad” and European Regional Development Funds (ERDF))

Intelligent system based on genetic programming for atrial fibrillation classification

This article focuses on the development of intelligent classifiers in the area of biomedicine, focusing on the problem of diagnosing cardiac diseases based on the electrocardiogram (ECG), or more precisely, on the differentiation of the types of atrial fibrillations. First of all, we will study the ECG, and the treatment of the ECG in order to work with it with this specific pathology. In order to achieve this we will study different ways of elimination, in the best possible way, of any activity that is not caused by the auriculars. We will study and imitate the ECG treatment methodologies and the characteristics extracted from the electrocardiograms that were used by the researchers who obtained the best results in the Physionet Challenge, where the classification of ECG recordings according to the type of atrial fibrillation (AF) that they showed, was realized. We will extract a great amount of characteristics, partly those used by these researchers and additional characteristics that we consider to be important for the distinction previously mentioned. A new method based on evolutionary algorithms will be used to realize a selection of the most relevant characteristics and to obtain a classifier that will be capable of distinguishing the different types of this pathology

Políticas Públicas frente a la problemática ambiental de la explotación minera en páramos

La situación socio-jurídica problémica planteada a lo largo del presente trabajo de investigación se configura en un conflicto distributivo ambiental, según las prerrogativas de la ecología política. Así las cosas, ha de entenderse que la teoría del desarrollo sostenible planteada en conjunto con la ecología política, no es suficiente para definir la situación, teniendo en cuenta las implicaciones económicas que esta puede llegar a cobijar, además de considerar que los alcances sociales y ambientales facilitan su clasificación. Es necesario resaltar, además, que el ordenamiento jurídico se queda corto al momento de establecer mecanismos para la protección de los ecosistemas de páramos. Esto se afirma después de haber enumerado todas y cada una de las disposiciones normativas que tratan sobre el tema, además de los antecedentes jurídicos mostrados a través de la recopilación de la política pública minera colombiana, los cuales son nulos en cuanto a protección de páramos. Por tanto, se confirma que la política minera colombiana posee fallas, no solo en su planteamiento sino en su regulación y ejecución. Las fallas de planteamiento de la política colombiana radican en la aplicación de la teoría del desarrollo sostenible, teoría que podría no ser suficiente para tratar el tema de minería extractiva, teniendo en cuenta que se fundamenta en el ámbito económico y los postulados de cuidado ambiental pueden ser tomados como insuficientes. Igualmente existen serias fallas en cuanto a comunicación entre las entidades estatales que crean, aplican y regulan la política minera colombiana. La política planteada por el Ministerio considera que la jurisprudencia genera inseguridad jurídica y las leyes reguladoras de la aplicación de las políticas no se aplican como se espera. Además, e documento resalta la falta de actualización de los Planes de Ordenamiento Territorial, en cuanto a los usos del suelo, teniendo en cuenta que de esta manera se hace más fácil determinar que terrenos son propicios para la actividad extractivaThe problematic socio-legal situation raised throughout this research work is configured in an environmental distributive conflict, according to the prerogatives of political ecology. Thus, it must be understood that the theory of sustainable development proposed in conjunction with political ecology is not enough to define the situation, taking into account the economic implications that this may come to cover, in addition to considering that the social and economic environmental factors facilitate their classification. It is also necessary to highlight that the legal order falls short when establishing mechanisms for the protection of paramo ecosystems. This is affirmed after having enumerated each and every one of the normative dispositions that treat on the subject, besides the legal antecedents shown through the compilation of the Colombian public mining policy, which are null as far as protection of páramos. Therefore, it is confirmed that the Colombian mining policy has flaws, not only in its approach but also in its regulation and execution. The failures of the Colombian policy approach lie in the application of the theory of sustainable development, a theory that may not be enough to deal with the issue of extractive mining, taking into account that it is based on the economic sphere and environmental care postulates can be taken as insufficient. There are also serious failures in terms of communication between the state entities that create, apply and regulate the Colombian mining policy. The policy proposed by the Ministry considers that the jurisprudence generates legal uncertainty and the laws regulating the application of the policies do not apply as expected. In addition, the document highlights the lack of updating of Land Management Plans, in terms of land use, taking into account that in this way it is easier to determine what land is favorable for extractive activit

Risk and outcomes of COVID-19 in patients with multiple sclerosis

Background and purpose Limited information is available on incidence and outcomes of COVID-19 in patients with multiple sclerosis (MS). This study investigated the risks of SARS-CoV-2 infection and COVID-19-related outcomes in patients with MS, and compared these with the general population. Methods A regional registry was created to collect data on incidence, hospitalization rates, intensive care unit admission, and death in patients with MS and COVID-19. National government outcomes and seroprevalence data were used for comparison. The study was conducted at 14 specialist MS treatment centers in Madrid, Spain, between February and May 2020. Results Two-hundred nineteen patients were included in the registry, 51 of whom were hospitalized with COVID-19. The mean age ± standard deviation was 45.3 ± 12.4 years, and the mean duration of MS was 11.9 ± 8.9 years. The infection incidence rate was lower in patients with MS than the general population (adjusted incidence rate ratio = 0.78, 95% confidence interval [CI] = 0.70–0.80), but hospitalization rates were higher (relative risk = 5.03, 95% CI = 3.76–6.62). Disease severity was generally low, with only one admission to an intensive care unit and five deaths. Males with MS had higher incidence rates and risk of hospitalization than females. No association was found between the use of any disease-modifying treatment and hospitalization risk. Conclusions Patients with MS do not appear to have greater risks of SARS-CoV-2 infection or severe COVID-19 outcomes compared with the general population. The decision to start or continue disease-modifying treatment should be based on a careful risk–benefit assessment.post-print996 K

The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment

The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourteenth from SDSS overall (making this, Data Release Fourteen or DR14). This release makes public data taken by SDSS-IV in its first two years of operation (July 2014-2016). Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey (eBOSS); the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data driven machine learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS website (www.sdss.org) has been updated for this release, and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020, and will be followed by SDSS-V.Comment: SDSS-IV collaboration alphabetical author data release paper.

PERSPECTIVA PSICOSOCIAL DE LOS DERECHOS HUMANOS

Hoy en día es imprescindible abordar el problema de los derechos desde una perspectiva holística que integre la posición que el individuo ocupa en la sociedad y el impacto de los hechos sociales sobre su persona. Esta perspectiva va por lo tanto más allá del enfoque clásico de las violaciones a los derechos civiles y políticos de los ciudadanos sino, también incluye sus derechos económicos, sociales y culturales. Cualquier enfoque de tipo holístico debe entender al ser humano en su ambiente, social, cultural, natural y en función a todas las estructuras existentes, por más sutiles que sean o invisibles que parezcan. Precisamente este libro permite apreciar la dimensión amplia y compleja del ser en sociedad y las interacciones que de ambas partes se generan y las ramificaciones que producen. No es un ejercicio fácil y los editores de este volumen han logrado un salto cuántico al poder congregar en un solo espacio miradas que en otras circunstancias podrían haber sido opuestas y hasta contrarias a nuestra comprensión de problemas que, en efecto, tienen raíces comunes. El libro está dividido en 5 secciones, El espíritu de los tiempos actuales y los Derechos Humanos, Construcción ciudadana y ejercicio de los Derechos Humanos, Violaciones a Derechos Humanos, victimizaciones y su atención, Ejercicio de los Derechos Humanos y situaciones disruptivas y Defensa y defensores de Derechos Humanos.Manuel Gutiérrez Romero Jessica Ruiz Magañ
