Simulación eficiente de dinámicas no markovianas mediante estados Max-Ent

En el presente trabajo estudiaremos el problema de resolución de la dinámica de un sistema no markoviano mediante las ecuaciones de Schrödinger y Lindblad, un problema de complejidad NP-hard, mediante la aproximación de los estados instantáneos por estados tipo Max-Ent con correlaciones de hasta dos cuerpos, un problema de complejidad - a priori - P. A tal fin, se usó el formalismo de dinámicas Gaussianas para dichos sistemas y un enfoque nuevo de dinámicas Gaussianas como una aplicación del Principio Max-Ent para la descripción de dinámicas abiertas y cerradas de sistemas cuánticos no markovianos.In this work we will study the problem of solving the Schrödinger and Lindblad equations for non-Markovian correlated multipartite quantum systems, a problem of NP-hard algorithmic complexity, by the means of approximating the instantaneous states by Max-Ent-type states, counting only up to two-body correlations; a priori a problem of P complexity. To that end, we implemented the Gaussian dynamics formalism for such systems and a new Gaussian dynamics approach as an application of the Max-Ent Principle for the description of open and closed dynamics for non-Markovian quantum systems.Facultad de Ciencias Exacta

Leveraging Container Technologies in a GIScience Project: A Perspective from Open Reproducible Research

Scientific reproducibility is essential for the advancement of science. It allows the results of previous studies to be reproduced, validates their conclusions and develops new contributions based on previous research. Nowadays, more and more authors consider that the ultimate product of academic research is the scientific manuscript, together with all the necessary elements (i.e., code and data) so that others can reproduce the results. However, there are numerous difficulties for some studies to be reproduced easily (i.e., biased results, the pressure to publish, and proprietary data). In this context, we explain our experience in an attempt to improve the reproducibility of a GIScience project. According to our project needs, we evaluated a list of practices, standards and tools that may facilitate open and reproducible research in the geospatial domain, contextualising them on Peng’s reproducibility spectrum. Among these resources, we focused on containerisation technologies and performed a shallow review to reflect on the level of adoption of these technologies in combination with OSGeo software. Finally, containerisation technologies proved to enhance the reproducibility and we used UML diagrams to describe representative work-flows deployed in our GIScience project.This work has been funded by the Generalitat Valenciana through the “Subvenciones para la realización de proyectos de I+D+i desarrollados por grupos de investigación emergentes” programme (GV/2019/016) and by the Spanish Ministry of Economy and Competitiveness under the subprogrammes Challenges-Collaboration 2014 (RTC-2014-1863-8) and Challenges R+D+I 2016 (CSO2016-79420-R AEI/FEDER, EU).

The Engagement of the Social Networks in the ACB Basketball League

We currently live in a technological age, and in continuous growth. Within this age, social networks have emerged as a way of communicating and creating value in branding. Sports clubs have adapted their way of communicating with their fans and have made social networks an indispensable tool for their daily communication. The aim of the present study is to analyze how the position in the ranking affects the engagement of the social networks of 18 basketball clubs that make up the Endesa ACB League during match days 16 to 34. Specific formulas were used in study to analyze social networks of Facebook, Twitter, Instagram, and YouTube. The results show great variability of engagement results as well as a positive correlation between the ranking in the table and engagement on the different social networks, with Instagram having the highest correlation of all the social networks.Iundenia, Centro de Formacion de Tecnicos Deportivos CIF B-18905760 18013708startup Football Connection (FOOC) 4.073.37

The data for 200 objects are made public, including the 100 galaxies of the First Public Data Release (DR1). Data were obtained with the integral-field spectrograph PMAS/PPak mounted on the 3.5 m telescope at the Calar Alto observatory. Two different spectral setups are available for each galaxy, (i) a lowresolution V500 setup covering the wavelength range 3745–7500 Å with a spectral resolution of 6.0 Å (FWHM); and (ii) a medium-resolution V1200 setup covering the wavelength range 3650–4840 Å with a spectral resolution of 2.3 Å (FWHM). The sample covers a redshift range between 0.005 and 0.03, with a wide range of properties in the color–magnitude diagram, stellar mass, ionization conditions, and morphological types. All the cubes in the data release were reduced with the latest pipeline, which includes improved spectrophotometric calibration, spatial registration, and spatial resolution. The spectrophotometric calibration is better than 6% and the median spatial resolution is 200 : 4. In total, the second data release contains over 1.5 million spectra.Instituto de Salud Carlos III Spanish Government AYA2010-15081 AYA2010-15196European Union (EU) PCIG12-GA-2012-326466Spanish Ministry of Economy and Competitiveness (MINECO) AYA2010-21322-C03-02 AIB-2010-DE-00227FP7 Marie Curie Actions of the European Commission, via the Initial Training Network DAGAL under REA 289313Ministry of Economy, Development, and Tourism's Millennium Science Initiative IC12009Comision Nacional de Investigacion Cientifica y Tecnologica (CONICYT) CONICYT FONDECYT 3140566Fundacao para a Ciencia e a Tecnologia (FCT) from FCT (Portugal) SFRH/BPD/66958/2009Spanish programme of International Campus of Excellence Moncloa (CEI)European Research Council (ERC)Junta de Andalucia TIC 114 PO08-TIC-3531French National Research Agency (ANR) ANR-12-BS05-0016-02Spanish Government AYA2010-21887-C04-02FCT Investigador Contract - FCT/MCTES (Portugal)European Commission Joint Research Centre European Social Fund (ESF)FCT - FCT-MEC (PIDDAC) FCOMP-01-0124-FEDER-029170 FCT PTDC/FIS-AST/3214/2012European Union (EU)Spanish Ministerio de Educacion, Cultura y Deporte by FPURamon y Cajal program from the Spanish Ministry of Economy and Competitiveness (MINECO) ATA2010-21322-C03-02European Union (EU) 303912European Career Re-integration GrantSpanish Government RyC-2011-09461 AYA2013-47742-C4-3-PEuropean Union (EU) FP7-PEOPLE-2013-IRSES-612701PTDC/FIS-AST/3214/2012Science & Technology Facilities Council (STFC) ST/K000985/

The psychometric parameters of the Spanish Form of the Arabic Obsessive Compulsive Scale (S-AOCS)

The aim of this study was to describe the psychometric properties of the Spanish version ofthe Arabic Obsessive Compulsive Scale (S-AOCS). The original scale was first translated into Spanish by language experts using the back translation procedure, and then administered to a total of 312 Spanish university students from Barcelona. Four-week test-retest was 0.88 indicating its high temporal stability. Cronbach's alpha value of the S-AOCS reached 0.82 indicating its good internal consistency. The S-AOCS correlated 0.72 with the Maudsley Obsessive-Compulsive Inventory and 0.56 with the Kuwait University. Anxiety Scale indicating good criterion-related validity. Finally, a principal axis analysis with Oblimin rotation was carried out. Five factors were extracted, accounting for 37.88% of the total variance. These factors were labeled: Obsessive thoughts and rumination (16.61%), Meticulousness and perfectionism (6.48%), Indecision and doubts (5.59%), Ritualism (4.74%) and Checking (4.45%). The results indicate that the S-AOCS administered to this Spanish sample yields good internal consistency, temporal stability, criterion-related validity and a five-factor structure reflecting important features of obsessive compulsive disorder. In general, the S-AOCS could be recommended in research on obsession-compulsion among Spanish college students

Ejercicio físico basado en descansos activos sobre la función cognitiva y la competencia matemática en estudiantes universitarios de grado

A review of the literature has demonstrated the impact of active breaks (AB) on students’ cognition and academic performance. Despite the evidence, undergraduate students seem to remain passive during the lessons as the teaching is mostly traditional and revolves around the teacher. To break with this tendency in the university context, we included physical activity (PA) breaks during lessons. This study aimed to observe the acute effect of AB on the students’ attention and mathematical competence. A total of 25 undergraduate students (Mage = 23.36, SD = 1.98) participated in this study and performed an intervention under two conditions: i) control condition and ii) active-break condition. Results revealed that after receiving an AB (15 minutes) of moderate intensity students’ attention was improved. More specifically, participants were faster at D2 and their math tasks results improved.La literatura ha demostrado el impacto de los descansos activos (AB; active breaks en inglés) en la cognición y el rendimiento académico de los estudiantes. A pesar de la evidencia, los estudiantes universitarios parecen permanecer pasivos durante las lecciones, ya que la enseñanza es mayoritariamente tradicional y gira en torno al profesor. Para romper con esta tendencia en el contexto universitario, incluimos pausas de actividad física (AF) durante las clases. Este estudio de casos cruzados tiene como objetivo observar el efecto agudo de los descansos activos en la atención y la competencia matemática de los estudiantes. Un total de 25 estudiantes de grado (Medad = 23,36, DE = 1,98) participaron en este estudio y realizaron una intervención bajo dos condiciones: i) condición de control y ii) condición de descansos activos. Los resultados muestran que los estudiantes mejoraron su atención después de recibir una sesión de descanso activo (15 minutos) de intensidad moderada. En este sentido, los participantes fueron más rápidos en D2 y mejoraron sus resultados en la tarea de matemáticas

Should EU Land Use and Land Cover Data be managed with a NoSQL Document Store?

Land cover (LC) is a scientific landscape classification based on physical properties of earth materials. This information is usually retrieved through remote sensing techniques (e.g. forest cover, urban, clay content, among others). In contrast, Land use (LU) is defined from an anthropocentric point of view. It describes how a specific area is used (e.g. it is usual to indicate whether a territory supports an intensive, extensive use or it is unused). Both geospatial layers are essential inputs in many socio-economic and environmental studies. The INSPIRE directive provides technical data specifications for harmonization and sharing of voluminous LU/ LC datasets across all countries of the EU. The INSPIRE initiative proposes Object-Oriented Modelling as a data modelling methodology. However, the most used Geographic Information Systems (GIS) are built upon relational databases. This may jeopardize LU/LC data usability, since GIS practitioners will eventually face the object-relational impedance mismatch. In this paper, the authors introduce the SIOSE database (Spanish Land Cover and Land Use Information System), which was the first implementation of an object-oriented land cover and Land-use datamodel, in line with the recommendation of the INSPIRE Directive, separating both themes. SIOSE data can be downloaded as relational database files, where information describing each single LU/LC object is divided among several related tables, so database queries can be complex and time consuming. The authors show these technical complexities through a computational experience, comparing SQL and NoSQL databases for querying spatial data downloaded from SIOSE. Finally, the authors conclude that NoSQL geodatabases deserve to be further explored because they could scale for LU/LC data, both horizontally and vertically, better than relational geodatabases, improving usability and making the most of the EU harmonization efforts

Looking at Okuda’s artwork through GeoGebra: A Citizen Science experience

In this paper, we describe an experience to test the predominant presence of Delaunay triangulations in the artwork of Okuda, a quite famous, young, contemporary Spanish artist. We addressed this task involving, as a citizen science activity in a STEAM (Science, Technology, Engineering, Art, Mathematics) education context, several hundreds of students (of different kinds: secondary education, university undergraduates, in particular, following teacher training degrees). Each student was asked to select an Okuda archive and, with the concourse of a dynamic geometry program provided with some computational geometry commands, to measure the ratio of coincident triangles in Delaunay’s and artist’s triangulations, over an ample region of the chosen artwork. The results show a very large percentage of coincidence ratios. We conclude with some reflections about how to interpret this fact, and about the potential role of future, enhanced, dynamic geometry systems to automatically address similar issues, concerning mathematical properties of figures from the real worl

Relación entre clima social familiar y rendimiento académico en estudiantes del 1º AL 4º grado de educación secundaria de la I.E. Nº 11009 Virgen de la Medalla Milagrosa – Garcés – José Leonardo Ortiz

La dinámica familiar en las últimas décadas ha estado influenciada por cambios científicos- tecnológicos, socio- económicos, político - culturales etc., situación que ha condicionado su estructura y funcionalidad, a pesar de las dificultades y limitaciones ha demostrado una gran adaptabilidad para adecuarse a las continuas transformaciones sociales. Es innegable la importancia que tiene la familia para su supervivencia del individuo y el moldeamiento de su personalidad. La utilidad de la presente investigación radica en que se obtendrá información objetiva que permita conocer de qué manera están relacionados el clima social familiar y el rendimiento académico y, de esta forma, dar respuesta a la preocupación institucional sobre los logros de aprendizaje alcanzados por los estudiantes; además a partir de lo investigado se viabilice la implementación y desarrollo de diversas actividades en las diferentes instancias encargadas del quehacer educativo, en especial en el ámbito familiar, priorizando las actividades preventivas y de concientización en el rol formativo de sus hijos; por otro lado servirá de fuente de consulta para posteriores investigaciones y de soporte teórico para la implementación de programas que contribuyan al fortalecimiento de la dinámica familiar y el mejoramiento del rendimiento académico. Conocedores que en nuestra jurisdicción existen escasas investigaciones al respecto, pretendemos dar respuesta científica a dicha problemática y en consecuencia realizar las recomendaciones a las autoridades institucionales correspondientes.Tesi
