Aberrations introduced by the atmospheric turbulence in large telescopes are compensated using adaptive optics systems, where the use of deformable mirrors and multiple sensors relies on complex control systems. Recently, the development of larger scales of telescopes as the E-ELT or TMT has created a computational challenge due to the increasing complexity of the new adaptive optics systems. The Complex Atmospheric Reconstructor based on Machine Learning is an algorithm based on artificial neural networks, designed to compensate the atmospheric turbulence. During (...) recent years, the use of GPUs has been proved to be a great solution to speed up the learning process of neural networks, and different frameworks have been created to ease their development. The implementation of CARMEN in different Multi-GPU frameworks is presented in this paper, along with its development in a language originally developed for GPU, like CUDA. This implementation offers the best response for all the presented cases, although its advantage of using more than one GPU occurs only in large networks. (shrink)

The importance of professional competence lies in the effective application of job-oriented knowledge and skills which guarantee one’s successful adaptation to the work. This study analyzes the perception of the importance of physical activity and sports professionals’ competence in working with individuals with disabilities in Spain. As a descriptive quantitative study, face-to-face interviews were conducted through a survey to extract the data. The sample consisted of 214 PAS professionals working with people with disabilities. According to the results, the analyzed constituents (...) of professional competence are important for adequate performance, with the exception of competences of leadership and use of new technologies. It was also found that the perceived importance of each element of professional competence varies according to age, experience and training. Based on the obtained results, the degree of importance of each constituent of professional competence and its implication for the access of people with disabilities to high-quality physical activity and sports services was determined.

El objetivo de este ensayo es exponer la experiencia del pensar en obra, propia de una escritura filosófica que asume la singularidad de la configuración literaria en su más originario significado, como palabra memorable que testifica dicha experiencia, asumiéndola como problema del conocimiento. Intentaremos exponer este gesto que unifica diversas construcciones filosóficas que se han caracterizado por ofrecer un tramo de pensamiento en medio de la acción escritural, como punto de vista posible, como vía de acceso al recorrido de un (...) problema. Asumiendo que los límites entre filosofía y literatura se difuminan en una prosa que se deja guiar por la experiencia formativa –Bildung–nos inmiscuimos en la actualización de Miguel Morey desde el uso singular de la caja de herramientas de Nietzsche, junto a la compañía poética y filosófica de María Zambrano y Walter Benjamin.

La bibliografía reporta amplitud en lo concerniente al campo de la edición de revistas científicas donde los avances científico tecnológicos aportaron una nueva dinámica. Las nuevas tecnologías de la información y la comunicación sirven de herramientas y han transformado radicalmente el escenario de la evaluación de la publicación científica. Variedad de perspectivas, instrumentos e indicadores impactan en los procesos de evaluación. El objetivo de este trabajo es ofrecer una valoración del proceso actual de evaluación de las publicaciones científicas seriadas. Los (...) procedimientos utilizados son la revisión bibliográfica, análisis de textos y síntesis de los hallazgos desde lo teórico. Se concluye que la publicación científica seriada ha pasado a ser, más que un proceso singular de la comunicación científica, el modo fundamental de evaluación de la calidad del trabajo científico, de ahí la importancia de tener claridad y propuestas propias de los indicadores de la evaluación. There is amplitude in bibliography, regarding the edition of scientific journals, where the scientific technological achievements that have been made in recent times have contributed with a new dynamic. The edition in digital format has its name due to the appearance of the new information and communication technologies. The recently emerged perspectives, instruments and indicators impact evaluation of publications processes and the accreditation in the higher education. The aim of this document is to offer an assessment on the current situation of the evaluation process of serialized scientific publications through the use of indicators. The text analysis and bibliographic review procedures were used to achieve the previous goal. In conclusion, the serialized scientific publications have become the main way quality of scientific research evaluation rather than a specific process of scientific communication. That is why is important to be certain of the combination of indicators for evaluating the scientific publications. (shrink)

Juan de Vera’s El Enbaxador (1620) was one of the main treatises on the role of the ambassador in Early Modern Europe and the first one published in Spanish. At the time, Spain was no exception to the influence of Tacitus as a significant ancient author to inspire the political practice of the age. Juan de Vera, a nobleman and writer, soon an ambassador and entitled count, incorporated his own reading of Tacitus into El Enbaxador. Justus Lipsius, the outstanding editor (...) of Tacitus’ works, was also a main source for this book which was defined by John Elliott as a ‘quintessentially Lipsian handbook for diplomats’. The focus of this article is on Tacitus’ citations in El Enbaxador and their contexts within the book. My aim is to identify the specific themes for which Tacitus served as an exemplary source of guidance according to this particular text. Notably, some of such themes pertain to ambassadorial affairs, while others are common political topics in Early Modern Europe. Vera's reading of Tacitus in El Enbaxador gained wider dissemination beyond Spain as the work was subsequently translated into French and Italian. (shrink)

Incest taboos are universal, but it is questionable whether consensual incest should continue to be illegal. The most common argument in favor of the illegalization of consensual incest appeals to genetic risks and the harm to potential offspring. In this article, we examine whether public health concern is a sufficient reason to illegalize consensual incest. We posit that indeed, incest represents a risk, but this is not reason enough to illegalize incest. For, other circumstances of sexual intercourse may lead to (...) similar risks, and yet, such practices are not illegal. While those practices may represent an added risk to public health, to forbid them as a way to improve the genetic pool would be akin to eugenic program, and that is morally objectionable. This does not imply that consensual incest ought to be legal, for there may be other good reasons to illegalize it. But they do not relate to public health and genetic risks, and consequently, medical practitioners and public health officials ought to avoid using their medical authority as a platform to make moral pronouncements.

In 1989, Thomas Donaldson requested the California courts to allow physicians to hasten his death. Donaldson had been diagnosed with brain cancer, and he desired to die in order to cryonically preserve his brain, so as to stop its further deterioration. This case elicits an important question: is this a case of euthanasia? In this article, we examine the traditional criteria of death, and contrast it with the information-theoretic criterion. If this criterion is accepted, we posit that Donaldson’s case would (...) have been cryocide, but not euthanasia. We then examine if cryocide is an ethically feasible alternative to euthanasia. To do so, we rely on the ethical doctrine of double effect. (shrink)

El ejercicio utópico de la voluntad política que caracteriza el XIX latinoamericano se desgrana en las categorías de unidad continental, unidad cultural, unidad en el concepto de Patria, etc.; clausurando un apretado siglo de extrema densidad social y política, un siglo de utopía en el discurso. Una Ilustración insuficiente, el coste del hibridismo, las comunidades imaginadas, las dependencias encadenadas, las resistencias, los logros y los fracasos, traducen el sacrificio, la traición y la inconclusión de la tarea emancipatoria. Si podemos contemplar (...) hoy día el descubrimiento de América como el comienzo de una empresa civilizatoria, y admirar sus obras más allá del trabajo infatigable de una destrucción que no ha cesado, es sólo en virtud de esta tradición de crítica y resistencia , a lo largo de un proceso social, artístico y literario ininterrumpido hasta el día de hoy.

En este artículo se busca indagar, por un lado, las aporías que Gadamer detecta en la propuesta epistemológica de Dilthey y, por el otro lado, las aporías que el propio Dilthey encuentra en el obrar de las ciencias del espíritu. El objetivo de este artículo será mostrar las limitaciones de la crítica gadameriana y reconocer que la obra de Dilthey excede el análisis exclusivamente objetivista. Esto permitirá demostrar que la filosofía de Dilthey es una indagación del mundo humano entendido como (...) mundo activo. En otros términos, sus estudios son más que una investigación epistemológica. Se buscará sostener que la fundamentación de las ciencias del espíritu desarrollada por él se sostiene gracias a su investigación sobre la dinámica de la vida humana, del mundo común e histórico donde actúa el hombre. This paper seeks to investigate, on one hand, the aporiae that Gadamer detects in Dilthey's epistemological theory, and, on the other hand, the aporiae that Dilthey himself finds in the work of the human sciences. The goal of this paper is to show the limitations of Gadamer's critique and to recognize that Dilthey's work exceeds the objectivist analysis. This will allow proving that Dilthey's philosophy is an inquiry into the human world understood as an active world. In other words, his studies are more than an epistemological investigation. I will seek to claim that the basis of the human sciences developed by him is the result of his research on the dynamics of human life, on the common and historical world where man acts. (shrink)

Adaptive optics are techniques used for processing the spatial resolution of astronomical images taken from large ground-based telescopes. In this work, computational results are presented for a modified curvature sensor, the tomographic pupil image wavefront sensor, which measures the turbulence of the atmosphere, expressed in terms of an expansion over Zernike polynomials. Convolutional neural networks are presented as an alternative to the TPI-WFS reconstruction. This technique is a machine learning model of the family of artificial neural networks, which are widely (...) known for its performance as modeling and prediction technique in complex systems. Results obtained from the reconstruction of the networks are compared with the TPI-WFS reconstruction by estimating errors and optical measurements. The reconstructed wavefronts from both techniques are compared for wavefronts of 153 Zernike modes. For this case, a detailed comparison and grid search to find the most suitable neural network is performed, searching between multi-layer perceptron, CNN and recurrent networks topologies. In general, the best network was a CNN trained for TPI-WFS reconstruction, achieving better performance than the reconstruction software from TPI-WFS in most of the turbulent profiles, but the most significant improvements were found for higher turbulent profiles that have the lowest r0 values.

As it has historically been the case with many pandemics, the Covid-19 experience will induce many philosophers to reconsider the value of medical practice. This should be a good opportunity to critically scrutinize the way medical research and medical interventions are carried out. For much of its history, medicine has been very inefficient. But, even in its contemporary forms, a review of common protocols in medical research and medical interventions reveal many shortcomings, especially related to methodological flaws, and more importantly, (...) conflicts of interests due to profit incentives. In the face of these problems, we propose a program of “gentle medicine”. This term, originally formulated by philosopher Jacob Stegenga, describes a form of medicine in which physicians intervene less than they currently do. As part of this general program, we advance a series of reform recommendations that could be enacted both by medical staff in their everyday practice, but also by public health officials and policymakers.

International large-scale assessments have gained much attention since the beginning of the twenty-first century, influencing education legislation in many countries. This includes Spain, where they have been used by successive governments to justify education policy change. Unfortunately, there was a problem with the PISA 2018 reading scores for this country, meaning the OECD refused to initially release the results. Therefore, in this paper we attempt to estimate the likely PISA 2018 reading scores for Spain, and for each region within. The (...) figure finally published by the OECD for Spain – in terms of reading scores – was 476.5 points, which is between the lower and upper bound of the interval we find (475 to 483 test points in 2018). Additionally, we report some robustness checks for the OCED countries participating in PISA 2018, which show that the difference between the actual scores and the ones we found with the imputation methods are quite close.

Batteries are a fundamental storage component due to its various applications in mobility, renewable energies and consumer electronics among others. Regardless of the battery typology, one key variable from a user’s perspective is the remaining energy in the battery. It is usually presented as the percentage of remaining energy compared to the total energy that can be stored and is labeled State Of Charge (SOC). This work addresses the development of a hybrid model based on a Lithium Iron Phosphate (LiFePO4) (...) power cell, due to its broad implementation. The proposed model calculates the SOC, by means of voltage and electric current as inputs and the latter as the output. Therefore, four models based on k-Means, Agglomerative Clustering, Gaussian Mixture and Spectral Clustering techniques have been tested in order to obtain an optimal solution. (shrink)

Rationale, aims and objectives Given the increasing prevalence of cataract and demand for cataract extraction surgery, patients must often wait to undergo this procedure. We validated a previously developed priority scoring system in terms of clinical variables, pre-intervention health status, appropriateness of surgery and gain in visual acuity (VA) and health-related quality of life (HRQoL).Methods Explicit prioritization criteria for cataract extraction created by a variation of the Research and Development (RAND) and University of California Los Angeles appropriateness methodology were retrospectively (...) applied to a prospective cohort of 5257 patients on waiting lists to undergo cataract by phacoemulsification at 17 hospitals in Spain. Demographic data, clinical data and data related to surgical technique were collected by trained ophthalmologists. Patients were evaluated by their ophthalmologist before the intervention and 6 weeks afterward. They also completed, by mail, the Visual Function Index (VF-14) before the intervention and 3 months afterward.Results High-priority patients experienced greater improvement in VA and HRQoL than those classified as intermediate or low-priority (P < 0.0001), even after adjusting by VA and the VF-14 score at baseline. The time to intervention was the same for high-priority patients as it was for intermediate and low-priority patients.Conclusions The priority score we developed identified patients most likely to experience the greatest improvements from cataract extraction. Use of this tool could provide a fairer and more rational way to prioritize patients for cataract extraction. (shrink)

This article is an exploratory study that intends to present semantic interoperability initiatives in the area of information science and computer science. It discusses these initiatives, focusing on open science and eScience, aiming at pointing out similarities and differences in the methodologies used for an intelligent retrieval of data in heterogeneous environments that do not benefit a universal language. We will illustrate seminal initiatives regarding the compatibility of languages in information science and the alignment and semantic mapping in the area (...) of computer science, emphasizing what they have in common and their differences, showing that those seminal initiatives are still relevant nowadays. In this perspective, we want to bring up discussions about methodologies that supports a kind of “intermediate language” that allows the compatibility of research resources, semantically interconnecting their contents without forcing the use of a single language, but of a switching language, such as a metalanguage that guarantees to keep the differences of each community of speech.

This book seeks to arrive at a better understanding of the relationships between the objective and subjective aspects of time. It discusses the existence of fluent time, a controversial concept in many areas, from philosophy to physics. Fluent time is understood as directional time with a past, a present, and a future. We experience fluent time in our lives and we adopt a temporal perspective in our ways of knowing and acting. Nevertheless, the existence of fluent time has been debated (...) for both philosophical and scientific reasons, thus creating a rift between the subjective and objective aspects of time. Starting from the basic notion of points of view, or perspectives, this book explores the relationships between objective or external time, as it has been conceptualized by science, and subjective or internal time, which is involved in our lived experiences. It establishes a general framework encompassing the nature, structure and mode of existence of points of view, in which the objective and subjective aspects of time can be integrated. The book mainly addresses researchers and postgraduates in philosophy and logic. Additionally, it offers inspiration for physicists and computer scientists involved in the modeling and simulation of complex behaviors for which the representation of internal time should be considered together with the notion of objective, external time.
