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.

Night: The presence of the absence, the dissolution of the person in the night, the horror of being, the reality of the unreal, it takes us more to the absence of God than to God, to the absence of every entity. Dawn: Not being conscious of the existence of that unchangeable supposed centre of the person within time does not mean that we cannot be able to explain the not static changeable and relational personal identity in other ways. Day: It (...) is me who flows, but I am not in the flow like a support from where life flows, I am flowing in my own reality. This is not similar to an egology, it does not mean that everything exists and is loved to me, but it does mean that everything is seen and loved for me. (shrink)

Noche: La presencia de la ausencia, la disolución de la persona en la noche, el horror de ser, la realidad de lo irreal hacen que la noción de il y a �más que a Dios nos lleve a la ausencia de Dios, a la ausencia de todo ente�. Amanecer: No ser consciente de la existencia de ese supuesto centro inalterable de la persona dentro del tiempo no quiere decir que no seamos capaces de explicar la alterable y relativa identidad personal (...) de otras maneras. Día: Soy yo quién fluye, pero yo no estoy en el flujo como un apoyo de donde la vida fluya; yo estoy fluyendo en mi propia realidad. Esto no es similar a una egología, no significa que todo exista y sea amado por mí, sino que quiere decir que todo es visto y amado por mí. (shrink)

Lo icónico siempre se ha empleado para vehicular conocimientos de un modo propio con distintos grados de validez. En este artículo se busca pensar esta cuestión a propósito del fenómeno pictorial de nuestra época: las “nuevas imágenes técnicas”. Así, tras delimitar sus características, se especificarán sus modulaciones en el campo científico, tomando las neuroimágenes como estudio de caso, y en el artístico, haciendo hincapié en el arte algorítmico. Se pondrán en tela de juicio cinco nociones estético-epistémicas: verdad, realidad, novedad, imaginación (...) y creatividad; perfilando finalmente la posibilidad de genuina creatividad en la estética algorítmica a partir del concepto de “probabilidad’’. Palabras claves: Teoría de la imagen; Imágenes técnicas; Neuroimagen; Arte algorítmico; Estética contemporánea. (shrink)

RESUMEN El presente trabajo de revisión expone cómo las prácticas de gestión en la anestesiología deben ser modificadas para encarar las cambiantes necesidades de pacientes, otros profesionales y sistemas sanitarios, a fin de mantener una función significativa en la atención sanitaria. Los servicios de anestesia han adoptado una amplia variedad de modelos para hacer frente a las necesidades del medio local, la relación entre los anestesiólogos y la comunidad, y los papeles desempeñados por los anestesiólogos en el tratamiento perioperatorio. El (...) sistema sanitario cubano se encuentra inmerso en un proceso de permanente adecuación de sus servicios a los problemas, demandas y necesidades de la población cubana y sus determinantes. Por ello, objetivo es exponer consideraciones teóricas en función del perfeccionamiento del servicio de Anestesiología y Reanimación. ABSTRACT This review paper presents how anesthesiology management practices must be modified in order to deal with the changing needs patients, other professionals and health systems have, in order to maintain a significant function in health care. Anesthesiology services have adopted a wide variety of models to face up to the needs the city, the relationship between anesthesiologists and the community and the role anesthesiologists play in perioperative treatment have. The Cuban health system services are in a process of permanent adaptation to the problems, demands and needs the Cuban population and its determinants have. For that reason, this paper aims at presenting theoretical considerations towards the improvement of the Anesthesiology and Resuscitation service. (shrink)

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)

In western cultures, when it comes to places of worship and liturgies, music, acoustics and architecture go hand in hand. In the present study, we aimed to investigate whether the emotions evoked by music are enhanced by the acoustics of the space where the music was composed to be played on. We explored whether the emotional responses of western naïve listeners to two vocal pieces from the Renaissance, one liturgical and one secular, convolved with the impulse responses of four Christian (...) temples from the United Kingdom, were modulated by the appropriate piece/space matching. In an alternative forced choice task where participants had to indicate their preference for the original recording of the piece (not convolved with any temple-like acoustics) vs. the convolved one, no significant differences were found. However, in the tasks where participants rated their emotional in response to each piece and acoustic condition, the factorial ANCOVA analyses performed on the results revealed significant effects. We observed that, across pieces and spaces, participants found the temple-like acoustics as more transcendent, compared to the acoustics of the original version of the pieces. In addition, they rated the secular piece as more tender and the liturgical piece as more expressive in its original versions, compared to the convolved ones. We conclude that the acoustic signature of the four Christian temples causes an exaltation of certain emotions on listeners, although this effect is not associated to one or another musical piece.

Adults (more than 18 years old) are likely to reproduce the habits that they acquired during childhood and adolescence (from 6 to 16 years old). For that reason, teachers and parents have the responsibility to promote an active and healthy lifestyle in children and adolescents. Even though every school subject should promote healthy activities, Physical Education (PE) is the most important subject to foster well-being habits associated to healthy lifestyle during sport practice and other kinds of active tasks. Indeed, there (...) are many factors that influence the acquisition of healthy habits that should be taken into account when programs and activities are implemented in both educational and extracurricular context. In this sense, psychological and social factors are of utmost importance to achieve optimal experiences for an active and healthy lifestyle. However, due to the myriad of studies analyzing different factors in different contexts, there could be confusion when programs and pedagogical strategies are applied in educational or extracurricular contexts. The objective of this investigation is to analyze the state of art of the psychosocial factors which influence the engagement in physical activities and sport practice. The keywords used in this review were mainly: ‘Self-Determination Theory’, ‘motivation’, ‘Psychological need satisfaction, ‘physical activity and sport engagement’, ‘Elementary Education’, ‘Secondary Education’, ‘Physical Education’. The articles were selected according to the following criteria: (a) peer-reviewed original research published in international journals indexed in JCR or SJR, (b) published in English or Spanish, (c) about psychosocial factors which influence the physical activity and sport engagement, (b) in educational or extracurricular context. Research articles selected were found through nine databases. It was observed that physical activities and sport practice engagement are closely related to psychological factors. In particularly, intrinsic motivation was able to determine the active participation in any activity, including physical activity and sport practice during the implementation of Small-Sided Games and other kinds of pedagogical strategies (e.g., Pedagogical Models). Motivation was also closely related to flow state. Finally, these variables should be considered in order to organize effective programs to promote an active and healthy lifestyle in Physical Education classes. (shrink)

ObjectiveCOVID-19 caused a complete stop in non-professional sports. The use of face masks for team sports is not a widely used measure in non-professional sports. The study aimed to evaluate the perception about using the mask and the adaptation difficulties related to training and competition in team sports following the FISICOVID-DXTGALEGO protocol.MethodsSeven hundred eighty-seven handball players from the Galician Handball Federation were followed during their return to participation after months of confinement through an electronic questionnaire of perception and experience on (...) the use of a mask.ResultsThere is an excellent adaptation to the mask in training and competition with medium and high correlations. The 86,41% of players reported an adaptation to the mask in 3 weeks with a three times a week training frequency. The negative opinion on the mask was drastically reduced after use. The 80,44% of players considered the use of a mask as an essential measure to resume competitions.ConclusionsIt is very feasible to adapt to training and compete with a mask in a short period. The use of a mask following these protocols changed previous opinions on the disadvantages of the mask during training and competition. (shrink)

Induced abortion is a worldwide practice and its legalisation is a persistent demand of the women’s movement. Although in the academic literature there are numerous studies that address the study of fertility, nowhere near as much attention has been given to the analysis of induced abortion and its determining factors, and even less to the consideration of gender equality as a variable through which to understand it. This article focuses on the influence of gender equality on the rate of induced (...) abortion in different European countries. To that end the authors have constructed an econometric panel data model with information from 26 European countries for the period 2006–2011. They have analysed comparative indicators of the gender gap in terms of education, employment and wages. In addition, they have taken into account sociodemographic covariables such as the average age of motherhood, the migration rate and the percentage of births to unmarried mothers in each country. Also, as contextual factors the authors used the Human Development Index and an indicator of the legislation on abortion in the countries studied, as well as the percentage of the population who identify as having religious beliefs. The results show that the induced abortion rate is conditioned not only by national legislation on abortion, but also by gender equalities, specifically that as gender inequality decreases, so too does the frequency of induced abortions. These findings have clear political implications, showing as they do how improvements in the status of women, particularly with respect to their social and economic rights, impact on women’s reproductive decisions.

This paper is an attempt to point that a most fitting way of accounting for rule-following is seeing the knowledge involved in this behaviour as a specifically practical one. "Practical" here is taken from the Continental tradition which dates back to Aristotle and has Gadamer as its last mentor. In this way, rule-following comes to be related to taste and aesthetics.

The objective of this article is to analyse cultural influences when French companies cooperate with Mexican companies (subsidiaries of the French, established in Mexico) in the field of automotive manufacturing. An OEM supplier and a final assembly plant were selected to perform the study. Interviews with the workers, supervisors and managers have been performed. Case studies were collected in order to analyse the problems and to illustrate technical as well as cultural solutions. The analysis showed that important differences and coincidences (...) in the manufacturing solutions could be explained from the cultural (French and Mexican) standpoint. The conclusions integrate some recommendations for French and Mexican companies that are in actual cooperation or that are planning to globalise in the corresponding countries. (shrink)

Background: COVID-19 has taken many lives worldwide and due to this, millions of persons are in grief. When the grief process lasts longer than 6 months, the person is in risk of developing Complicated Grief Disorder. The CGD is related to serious health consequences. To reduce the probability of developing CGD a preventive intervention could be applied. In developing countries like Mexico, the psychological services are scarce, self-applied interventions could provide support to solve this problem and reduce the health impact (...) even after the pandemic has already finished.Aims: To design and implement a self-applied intervention composed of 12 modules focused on the decrease of the risk of developing CGD, and increasing the life quality, and as a secondary objective to reduce the symptomatology of anxiety, depression, and increase of sleep quality. The Intervention Duelo COVID follows the principles of User Experience and is designed according to the needs and desires of a sample of the objective participants, to increase the adherence to the self-applied intervention, considered one of the main weaknesses of online interventions.Methods: A Randomized Controlled Trial will be conducted from the 22nd of December of 2020 to the first of June 2021. The participants will be assigned to an intervention with elements of Cognitive Behavioral Therapy, Acceptance and Commitment Therapy, Mindfulness and Positive Psychology. The control group will be a wait-list condition, that will receive the intervention 1.5–2 months after the pre-measurement were taken. The Power Size Calculation conducted through G*Power indicated the need for a total of 42 participants, which will be divided by 21 participants in each group. The platform will be delivered through responsive design assuring with this that the intervention will adapt to the screen size of cellphones, tablets, and computers.Ethics and Dissemination: The study counts with the approval of the Research Ethics Committee of the Autonomous University of Ciudad Juárez, México, and it is registered in Clinical Trials. The article is sent and registered in clinical trials before the recruitment started. The results will be reported in future conferences, scientific publications, and media. (shrink)

In daily academic life, students are exposed to a wide range of potentially stressful situations which could negatively affect their academic achievement and their health. Among the factors that could be weakened by academic stress, attention has been paid to expectations of self-efficacy, which are considered one of the most important determinants for student engagement, persistence, and academic success. From a proactive perspective, research on academic stress has emphasized the importance of coping strategies in preventing harmful consequences. In recent years, (...) there has been a growing interest in discovering the extent to which individuals are able to combine different coping strategies and the adaptive consequences this flexibility entails. However, studies using this person-centered approach are still scarce in the academic context. On that basis, this current study had two objectives: (a) to examine the existence of different profiles of university students based on how they combined different approach coping strategies (positive reappraisal, support seeking, and planning); and (b) to determine the existence of differences in general expectations of self-efficacy between those coping profiles. 1072 university students participated in the study. The coping profiles were determined by Latent Profile Analysis (LPA). The differences in the self-efficacy variable were determined using ANCOVA, with gender, university year, and degree type as covariates. Four approach coping profiles were identified: (a) low generalized use of approach coping strategies; (b) predominance of social approach coping approaches; (c) predominance of cognitive approach coping approaches; (d) high generalized use of approach coping strategies. The profile that showed that a greater combination of the three strategies was related to higher general self-efficacy expectations, and vice versa. These results suggest that encouraging flexibility in coping strategies would help to improve university students’ self-efficacy. (shrink)

Expondré a continuación algunas notas sobre el pensamiento económico en América Latina a finales del siglo XVIII y comienzos del XIX. Me referiré al pensamiento ilustrado y al mercantilismo, y haré entrar a una filosofía que ejerció bastante influencia entonces -con particular relevancia desde finales de la década de 1810- en España e Iberoamérica, en un episodio poco estudiado en la historia de las ideas: el utilitarismo.

Hailed as the most influential book ever written in favor of freedom, John Stuart Mill’s On Liberty is a contradictory and imprecise work. Mill’s notion of liberty coexists with anti-liberal ideas. He defended the private property of capitalists, but not of landowners. He criticized protectionism, but made an exception for infant industries. He defended competition, but set limits on it. He criticized general public education, but allowed the State to force citizens to study. He defended women and men’s freedom, but (...) not the freedom to choose the number of children they wanted to have, or decide about their education, or bequeath goods to them. He said parting from laissez faire was bad unless it produced some good. This admired friend of liberty could not find the logic in family, marriage, religion, tradition, morality, custom; he saw them only as repressive obstacles to freedom. A book supposedly upholding liberty ignores or disdains natural or pre-legal rights, and directs the bulk of its criticism not against the legal or political power of the State but against the tyranny of public opinion.

Actualmente los estudios de Ciencia, Tecnología y Sociedad constituyen un importante espacio de trabajo en la política pública, la educación y la investigación. La introducción de nuevos procedimientos y tecnologías en la atención médica debe analizarse desde la perspectiva de los estudios de CTS porque requiere de un sustento científico-tecnológico y tiene que cumplir, entre otros, con los requisitos éticos de aplicabilidad a los seres humanos. La utilización secuencial de los antimicrobianos en el tratamiento postoperatorio de la apendicitis aguda complicada (...) en los niños, constituye una modificación de la terapéutica comúnmente empleada en Cuba y en muchas instituciones de salud del mundo. El presente trabajo muestra una reflexión sobre los pilares científicos, tecnológicos y sociales que sustentan la aplicación de un nuevo protocolo de tratamiento con el uso secuencial de los antimicrobianos en los niños con apendicitis aguda complicada. Currently the studies of science, technology and society are an important field on the research, education and public policy. The introduction of new procedures and technologies on the health care system should be considered throughout the science, technology and society point of view. Sequential antibiotic therapy in the postoperative management of children with complicated acute appendicitis is analternative of the commonest therapeutic management for these children in Cuba and in many health care justifys around the world. This paper show the significance of science, technology and society associated with the use of the sequential antibiotic therapy for children with complicated acute appendicitis. (shrink)

RESUMEN Fundamentación: la intervención de los anestesiólogos durante el preoperatorio de los pacientes con fractura del tercio proximal del fémur no queda reducida a la recopilación de datos científicos de carácter biológico, es una exigencia actual enfrentarse al paciente con una profunda comprensión de su esencia social y desde una posición humanista. Objetivo: determinar las condiciones sociales del sufrimiento de los pacientes con fractura del tercio proximal del fémur durante el preoperatorio. Método: se realizó un estudio de revisión sistemática cualitativa, (...) con la información cualitativa descriptiva a través de la recolección, evaluación, verificación y síntesis de las evidencias existentes. Resultados: si está indicada la intervención quirúrgica, se asegura la prevención de la discapacidad en la población envejecida vulnerable o frágil con alto riesgo quirúrgico. La fragilidad como proceso dinámico produce la transición a mayor fragilidad y su vez conduce a un espiral de resultados adversos de salud con carácter multidimensional y progresivo. Discusión: la ética del cuidado destaca la importancia de valorar el sufrimiento del paciente, la necesidad y sensibilidad para responder de tal forma que se proteja al paciente y sus familiares de la sensación de aislamiento, abandono y discapacidad propios de la enfermedad. El cuidado es una actividad permanente y cotidiana de la vida de las personas, el cuidado por parte de los anestesiólogos incluye profesionalidad a lo cotidiano. ABSTRACT Background: the intervention of the anesthesiologists during the preoperatory of the patients with fracture of the third proximal of the femur is not reduced to the summary of scientific data of biological character; it is a current demand to face the patient with a deep understanding of its social essence and from a humanist position. Objective: to determine the social conditions of the suffering of the patients with fracture of the third proximal of the femur during the preoperatory. Method: it was carried out a study of qualitative systematic revision, with the descriptive qualitative information through the gathering, evaluation, verification and synthesis of the existent evidences. Results: if it is suitable the surgical intervention.The fragility like dynamic process produces the transition to more fragility and its time it drives to a hairspring ofadverse resultsof health with multidimensional character and progressive. Discusión: the ethics of the care highlights the importance of valuing the patient's suffering, the necessity and sensibility to respond in such a way that is protected to the patient and its relatives of the isolation sensation, abandonment of the illness. The care is a permanent and daily activity of the life of people the care on the part of the anesthesiologists. (shrink)

La formación profesional tiene un carácter contextualizado que responde a las exigencias que la época, la sociedad y el país reclaman a las universidades. La Estomatología en Cuba no se encuentra al margen de estos preceptos por lo que desarrolla un plan de estudio que acentúa la flexibilidad para realizar modificaciones necesarias y pertinentes. El estudiante al culminar la carrera debe brindar una atención estomatológica integral donde las anomalías dentomaxilofaciales constituyen la tercera línea de trabajo. Estas ocasionan afectaciones estéticas que (...) repercuten en la autoestima y adaptación social de niños y adolescentes por lo que se necesita de una orientación sicoeducativa, acción para la cual el profesional deberá estar preparado. A partir de las insuficiencias detectadas en el proceso formativo del estomatólogo, el objetivo del presente trabajo es proponer un curso propio sobre la temática para favorecer la graduación de un profesional capaz de resolver los problemas que afectan el complejo estomatognático con un enfoque biosicosocial. Los métodos empleados fueron el histórico-lógico y análisis-síntesis. Professional training has a contextualized nature which reflects the demands that the time, society and the country require from universities. In Cuba, Stomatology is not out of these precepts and therefore it carries out a syllabus that emphasizes flexibility to make necessary and appropriate changes. When students graduate, they must provide a complete stomatological care where dental maxillofacial anomalies are the third line of work. They cause aesthetic harm that affects children and teenagers' self-esteem and social adaptation which makes psych educational guidance necessary; a situation professional must be prepared for. Starting from the weak points discovered in the training process of stomatologists, a crash course in the subject is suggested in order to favor the graduation of professionals who are able to solve problems that affect the stomatognatic complex with a biopsychosocial approach, through the use of required methods, techniques and procedures.
