B-parameters of the complete set of matrix elements of (Delta B = 2) operators from the lattice

We compute on the lattice the ``bag'' parameters of the five (Delta B = 2) operators of the supersymmetric basis, by combining their values determined in full QCD and in the static limit of HQET. The extrapolation of the QCD results from the accessible heavy-light meson masses to the B-meson mass is constrained by the static result. The matching of the corresponding results in HQET and in QCD is for the first time made at NLO accuracy in the MSbar(NDR) renormalization scheme. All results are obtained in the quenched approximation.Comment: 27 pages (5 figures

The spin axes orbital alignment of both stars within the eclipsing binary system V1143Cyg using the Rossiter-McLaughlin effect

Context: The Rossiter-McLaughlin (RM) effect, a rotational effect in eclipsing systems, provides unique insight into the relative orientation of stellar spin axes and orbital axes of eclipsing binary systems. Aims: Our aim is to develop a robust method to analyze the RM effect in an eclipsing system with two nearly equally bright components. This gives access to the orientation of the stellar rotation axes and may shed light on questions of binary formation and evolution. Methods: High-resolution spectra have been obtained both out of eclipse and during the primary and secondary eclipses in the V1143Cyg system, using the high-resolution Hamilton Echelle Spectrograph at the Lick Observatory. The Rossiter-McLaughlin effect is analyzed in two ways: (1) by measuring the shift of the line center of gravity during different phases of the eclipses and (2) by analysis of the line shape change of the rotational broadening function during eclipses. Results: The projected axes of both stars are aligned with the orbital spin within the observational uncertainties, with the angle of the primary rotation axis beta_p=0.3+-1.5 deg, and the angle of the secondary rotation axis beta_s=-1.2+-1.6 deg, thereby showing that the remaining difference between the theoretical and observed apsidal motion for this system is not due to a misalignment of the stellar rotation axes. Both methods utilized in this paper work very well, even at times when the broadening profiles of the two stars overlap.[abridged]Comment: Accepted for publication in A&A; 11 pages, 9 figures, 3 tables ; a typo in the abstract has been correcte

Principios e interés de los test Bondad de Ajuste (GOF) para los modelos de captura–recaptura multiestado

Optimal goodness–of–fit procedures for multistate models are new. Drawing a parallel with the corresponding single–state procedures, we present their singularities and show how the overall test can be decomposed into interpretable components. All theoretical developments are illustrated with an application to the now classical study of movements of Canada geese between wintering sites. Through this application, we exemplify how the interpretable components give insight into the data, leading eventually to the choice of an appropriate general model but also sometimes to the invalidation of the multistate models as a whole. The method for computing a corrective overdispersion factor is then mentioned. We also take the opportunity to try to demystify some statistical notions like that of Minimal Sufficient Statistics by introducing them intuitively. We conclude that these tests should be considered an important part of the analysis itself, contributing in ways that the parametric modelling cannot always do to the understanding of the data.Los procedimientos óptimos de bondad de ajuste, aplicados a los modelos multiestado, son nuevos. Trazando un paralelismo con los correspondientes procesos de uniestado, presentamos sus articularidades y mostramos como el test general puede descomponerse en componentes susceptibles de ser interpretados. Todos los desarrollos teóricos están ilustrados con una aplicación del ya clásico estudio de los desplazamientos de la barnacla canadiense entre sus lugares de invernada. Mediante esta aplicación, presentamos un ejemplo de cómo los componentes susceptibles de ser interpretados nos proporcionan una idea de los datos que nos pueden llevar a la elección de un modelo general apropiado, pero también a veces a la invalidación de los modelos de multiestados en su conjunto. Se menciona entonces el método para calcular un factor de corrección de la sobredispersión. Aprovechamos esta ocasión para intentar también desmitificar algunas nociones estadísticas, como las Estadísticas Suficientes Mínimas, introduciéndolas intuitivamente. La conclusión es que estas pruebas deberían considerarse una parte importante del propio análisis, contribuyendo a la comprensión de los datos, de un modo que el modelaje paramétrico no siempre consigue

The Distance to the Large Magellanic Cloud from the Eclipsing Binary HV2274

The distance to the Large Magellanic Cloud (LMC) is crucial for the calibration of the Cosmic Distance Scale. We derive a distance to the LMC based on an analysis of ground-based photometry and HST-based spectroscopy and spectrophotometry of the LMC eclipsing binary system HV2274. Analysis of the optical light curve and HST/GHRS radial velocity curve provides the masses and radii of the binary components. Analysis of the HST/FOS UV/optical spectrophotometry provides the temperatures of the component stars and the interstellar extinction of the system. When combined, these data yield a distance to the binary system. After correcting for the location of HV2274 with respect to the center of the LMC, we find d(LMC) = 45.7 +/- 1.6 kpc or DM(LMC) = 18.30 +/- 0.07 mag. This result, which is immune to the metallicity-induced zero point uncertainties that have plagued other techniques, lends strong support to the ``short'' LMC distance scale as derived from a number of independent methods.Comment: 6 pages, including 2 pages of figures. Newly available optical (B and V) photometry has revealed -- and allowed the elimination of -- a systematic error in the previously reported determination of E(B-V) for HV2274. The new result is E(B-V) = 0.12 mag (as compared to the value of 0.083 reported in the original submission) and produces a DECREASE in the distance modulus of HV2274 by 0.12 mag.

Decision Analysis Linguistic Framework

Everyday human beings are faced with situations they should choose among different alternatives by means of reasoning and mental processes when solving a problem. Many of these decision problems are under uncertain environments including vague, imprecise and subjective information that is usually modeled by linguistic information due to the use of natural language and its relation to mental reasoning processes of the experts when expressing their judgments. In a decision process multiple criteria can be evaluated which involving multiple experts with different degrees of knowledge. Such process can be modeled by using Multi-granular Linguistic Information (MGLI) and Computing with Words (CW) processes to solve the related decision problems. Different methodologies and approaches have been proposed to accomplish this process in an accurate and interpretable way. In this paper we propose a useful Decision Analysis Framework to manage this kind of problems by using the Extended Linguistic Hierarchy (ELH), 2-tuples linguistic representation model and its computational method. The developed Framework has many advantages when dealing with a complex problem in a simple way and its capability of having easy and useful reasonably results.Sociedad Argentina de Informática e Investigación Operativ

Integrating basic competences into physical education (Pe) in Primary Education

El objeto de este estudio fue evaluar la percepción de los maestros de Educación Física (EF) del Principado de Asturias sobre el proceso de incorporación de las competencias básicas (CCBB) en el currículo del área. Un total de 151 maestros de EF (46,6% de la población) contestaron a un cuestionario ad hoc compuesto por 12 ítems mediante una escala Likert de 6 puntos. Los resultados mostraron una plena incorporación de las CCBB a las programaciones, sin embargo, el nivel de desarrollo en la práctica resulta ser más bajo. Ser mujer, joven y contar con una elevada formación específica emergieron como factores diferenciales del trabajo competencial. Las competencias de carácter transversal fueron valoradas de mayor relevancia que las relacionadas con determinadas áreas curriculares. Se discute la profundidad del cambio emprendido por los docentes y el supuestamente requerido. Finalmente, se abordan sus implicaciones de cara al tipo de formación específicaThe purpose of this study was to assess Primary Education Physical Education (PE) teachers’ perspectives of the process of incorporating the Basic Competences (BBCC) into the curriculum of the Principality of Asturias. A total of 151 PE teachers (46.6% of the whole population) answered an ad hoc questionnaire of 12 items using a 6-point Likert scale. The results showed a full incorporation of the BBCC in the PE program. However, the degree of development in practice turned out to be lower. Being female, young, and having a high-level and specific training emerged as differentiating factors. Cross-cutting skills were valued more than those related to the specific curricular areas. The depth of change undertaken by the teachers compared to the required changed are discussed. Finally, implications to address specific training are also introduce

Sport education model versus traditional model: Effects on motivation and sportsmanship

El objetivo de este trabajo fue comparar los efectos que provocan los modelos de enseñanza Tradicional y de Educación Deportiva en la motivación y deportividad del alumnado de educación física, incluyendo también un tercer nivel de tratamiento, variante del modelo de Educación Deportiva, en el que se empleó material autoconstruido. Se realizó un diseño cuasi-experimental con tres niveles de tratamiento y medidas pretest y postest de cuatro variables dependientes: metas de logro, metas de amistad, necesidades psicológicas básicas y la deportividad durante la enseñanza del ultimate. Accedieron a participar un total de 295 estudiantes de secundaria y bachillerato cuyas edades oscilaban entre los 12-17 años. Los resultados indicaron mejoras significativas en las metas de evitación del rendimiento, metas de amistad, necesidades psicológicas básicas y subescalas de deportividad en ambos grupos de Educación DeportivaThe goal of the present project was to compare the effects of three different instructional models: (Traditional, Sport Education and Sport Education with Self-Made Materials) on physical education students' motivation and sportsmanship. A quasi-experimental design with three levels of treatment was used. Pretest and posttest scores on achievement goals, friendship, psychological needs and sportsmanship were obtained after the application of a learning unit of ultimate in a school in the northern part of Spain. A total of 295 secondary school students, ages 12-17, agreed to participate. Results showed significant increases in performance-avoidance goals, friendship goals, basic psychological needs and sportsmanship in both Sport Education groups. Sport Education seems to offer more advantages than the traditional teaching method to develop adolescents achievement and social goals, as well as sportsmanship, in physical educatio

Partial Differential Equation-Constrained Diffeomorphic Registration from Sum of Squared Differences to Normalized Cross-Correlation, Normalized Gradient Fields, and Mutual Information: A Unifying Framework; 35632143

This work proposes a unifying framework for extending PDE-constrained Large Deformation Diffeomorphic Metric Mapping (PDE-LDDMM) with the sum of squared differences (SSD) to PDE-LDDMM with different image similarity metrics. We focused on the two best-performing variants of PDE-LDDMM with the spatial and band-limited parameterizations of diffeomorphisms. We derived the equations for gradient-descent and Gauss-Newton-Krylov (GNK) optimization with Normalized Cross-Correlation (NCC), its local version (lNCC), Normalized Gradient Fields (NGFs), and Mutual Information (MI). PDE-LDDMM with GNK was successfully implemented for NCC and lNCC, substantially improving the registration results of SSD. For these metrics, GNK optimization outperformed gradient-descent. However, for NGFs, GNK optimization was not able to overpass the performance of gradient-descent. For MI, GNK optimization involved the product of huge dense matrices, requesting an unaffordable memory load. The extensive evaluation reported the band-limited version of PDE-LDDMM based on the deformation state equation with NCC and lNCC image similarities among the best performing PDE-LDDMM methods. In comparison with benchmark deep learning-based methods, our proposal reached or surpassed the accuracy of the best-performing models. In NIREP16, several configurations of PDE-LDDMM outperformed ANTS-lNCC, the best benchmark method. Although NGFs and MI usually underperformed the other metrics in our evaluation, these metrics showed potentially competitive results in a multimodal deformable experiment. We believe that our proposed image similarity extension over PDE-LDDMM will promote the use of physically meaningful diffeomorphisms in a wide variety of clinical applications depending on deformable image registration

Efectos de dos formatos instructivos, Educación Deportiva e Instrucción Directa, en la respuesta psicológica de estudiantes de secundaria

The goal of this study was to examine the effects of two instructional approaches, Sport Education and Direct Instruction, in a large sample of Spanish secondary education students’ psychological response. 217 (113 males, 104 females) students (12-17 years) from one urban, coeducational high school (grades 8-11th) agreed to participate. On each grade, all subjects were randomly distributed in two study groups: the experimental group experienced Sport Education, while the comparison group experienced Direct Instruction. Several subscales extracted from different questionnaires (PLOC, BPNES, IMI, SGS-PE, PMCSQ-2) were used to measure the effects of the intervention program. All data was analyzed using the SPSS 19.0 statistical program. Results showed that the Sport Education group significantly improved intrinsic motivation, autonomy, competence, interest, boredom, social responsibility, social relationship and cooperative learning. The Direct Instruction group showed significant gains only in autonomy, social responsibility and cooperative learning. Sport Education can significantly promote adaptive psychological responses in adolescents.El objetivo de este estudio fue examinar los efectos de dos formatos instructivos, Educación Deportiva e Instrucción Directa, en la respuesta psicológica de un grupo de estudiantes de secundaria. 217 (113 varones, 104 mujeres) estudiantes (12-17 años) de un colegio urbano (de 1º a 4º ESO) accedieron a participar. En cada nivel, todos los sujetos fueron distribuidos aleatoriamente en dos grupos de estudio: el grupo experimental experimentó Educación Deportiva y el grupo comparativo experimentó Instrucción Directa. Diferentes sub-escalas extraídas de varios cuestionarios (PLOC, BPNES, IMI, SGS-PE, PMCSQ-2) fueron usadas para medir los efectos del programa de intervención. Los datos fueron analizados utilizando el programa estadístico SPSS 19.0. Los resultados mostraron que el grupo de Educación Deportiva mejoró de manera significativa la motivación intrínseca, la autonomía, la competencia, el interés, el aburrimiento, la responsabilidad social, las relaciones sociales y el aprendizaje cooperativo. El grupo de Instrucción Directa mostró mejoras significativas solo en autonomía, responsabilidad social y aprendizaje cooperativo. La Educación Deportiva puede promover respuestas psicológicas adaptativas en adolescentes
