Fat handles and phase portraits of Non Singular Morse-Smale flows on S^3 with unknotted saddle orbits

In this paper we build Non-singular Morse-Smale flows on S^3 with unknotted and unlinked saddle orbits by identifying fat round handles along their boundaries. This way of building the flows enables to get their phase portraits. We also show that the presence of heteroclinic trajectories imposes an order in the round handle decomposition of these flows; this order is total for NMS flows composed of one repulsive, one attractive and n unknotted saddle orbits, for n >1.Comment: 15 page

Multilingual media components directly embeddable in open educational resources in science and technology

The use and reuse of OER (Open Educational Resources) depends on several conditions. Amongst others, the richness of their metadata, their granularity and the languages ​​in which they are made available. This work aims to facilitate efficient production of graphical and language-neutral components. It is assumed that the STEM areas (Science, Technology, Engeneering and Mathematics) share a common mathematical language and, more intuitively, an iconographic approach linked to the structures that satisfy the formulas used in each case. The work is limited to these areas of knowledge, primarily as presentations and animations of very low granularity, which can be directly integrated into larger resources in any language. The overall research design consists of four stages: 1. Initially, the manual generation of presentations and animations, with no literal in any language, and very concisely focused (mainly, definitions of a single concept for each animation). Determination of common graphics primitives to differentiate the common subtasks: presentation of examples to make the concept emerge inductively, graphical construction of the definition, highlighting the generalization or instantiation steps, homogeneous use of icons for emphasising or posing a question to the observer .. . 2. Evaluation of the expressiveness and effectiveness of these resources. Currently, these resources are being presented to small groups of students. This fall begins a multilingual evaluation process on a larger scale: as part of a regular course at the UNED and as LabSpace course in the Open University. Here we attempt to clarify the appropriate assessment tools (preferably in the same graphics language) with the minimum amount of additional external comments to constitute a course in a particular language. 3. The first two stages must provide an intuitive and graphical interface of the selected formalism (mainly Discrete Mathematics and Logic). The third stage addresses the effect of changing the output device on the selection of the graphics primitives for each generic subtask. Possible variations of the graphical language will be studied in the context of HCI analyses. 4. Finally the approach addresses semi-automatic generation, via script, of these resources: from formal description of the definitions or processes (as described, for example, in OMDoc) to the production of the corresponding animation. Additionally, the injection of semantics should facilitate the link between different animations, the navigation and search of conceptual dependency and the identification of concepts that have supporting collections of resources as described. At this point, the current development of this work provides results for the first two stages described

Tunneling induced electron transfer between separated protons

We study electron transfer between two separated nuclei using local control theory. By conditioning the algorithm in a symmetric system formed by two protons, one can favored slow transfer processes, where tunneling is the main mechanism, achieving transfer efficiencies close to unity assuming fixed nuclei. The solution can be parametrized using sequences of pump and dump pi pulses, where the pump pulse is used to excite the electron to a highly excited state where the time for tunneling to the target nuclei is on the order of femtoseconds. The time delay must be chosen to allow for full population transfer via tunneling, and the dump pulse is chosen to remove energy from the state to avoid tunneling back to the original proton. Finally, we study the effect of the nuclear kinetic energy on the transfer efficiency. Even in the absence of relative motion between the protons, the spreading of the nuclear wave function is enough to reduce the yield of electronic transfer to less than one half.Comment: 7 pages, 8 figure

Antifascism and Wildness. “Partisan Ecologies” between the Spanish Civil War and the Global Warming Era

This short essay uses the concept of “partisan ecologies” in order to analyse certain past and present chapters on the relationship between anti-fascism and nature. According to the Swedish eco- Marxist Andreas Malm, wilderness has not only represented an essentialist idea resulting from the projections of conservationist environmentalism about a supposedly untouched nature, but has also been one of the real spaces of a modern antagonism. Taking this theoretical point of departure, the text describes the Alpine Battalion of the Sierra del Guadarrama during the Spanish Civil War and its resonances in some contemporary events

De un arte crítico a un arte socialista: el itinerario de León Ferrari y Ricardo Carpani como síntoma de las transformaciones históricas de la relación entre el arte y la política en Argentina (y América Latina) durante los años sesenta y setenta

It would be difficult to attempt to understand the radicalisation of the Argentinean art scene in the time spanning from the late fifties to the early seventies without turning to the intellectual career of two artists: Ricardo Carpani and León Ferrari. Both men exercised a marked influence over their contemporaries, becoming gravitational centres in the understanding and the development of the connections between art and politics during the period.Es difícil entender el fenómeno de radicalización de la escena artística argentina en el arco temporal que se extiende desde finales de los años cincuenta a principios de la década del setenta sin acudir al itinerario intelectual de dos artistas como Ricardo Carpani y León Ferrari. Ambos ejercieron una poderosa influencia sobre el sector del campo artístico nacional y latinoamericano más interesado por el arraigo social e histórico de sus obras, estableciéndose como verdaderos núcleos gravitacionales de la comprensión y el devenir de las relaciones entre el arte y la política durante el período

Psicología Clínica en Atención Primaria

Atención Primara (AP) es la puerta de entrada al Sistema Nacional de Salud (SNS) y constituye el pilar más importante de la sanidad pública. Pretende llegar a toda la población y se basa en principios de equidad, eficacia y coste-efectividad. La gran mayoría de los casos de pacientes con problemas psicológicos son atendidos en AP. Dentro de esta atención cabe distinguir: los trastornos mentales, las enfermedades crónicas que cursan con problemas psicológicos o estilo de vida no saludable y los problemas vitales estresantes.Universidad de Málaga.

Data extraction methodology to improve the gameplay experience in video games and to analyse the user's profile behaviour and its evolution

Los videojuegos son la principal fuente de entretenimiento en nuestros días y la que más beneficios genera en la industria de los contenidos audiovisuales. Para las compañías que desarrollan videojuegos es muy importante saber el perfil de los usuarios que adquieren sus videojuegos para, posteriormente, desarrollar contenido específico para dichos usuarios. Los usuarios, por otra parte, exigen un mayor realismo en la inteligencia artificial de los enemigos y un mayor nivel de dificultad, todo ello unido a una elevada capacidad de personalización del modo de juego. En el ámbito de la inteligencia artificial y de la personalización existen videojuegos con mecánicas dinámicas que hacen que cada partida tenga una experiencia única. En este trabajo se pretende, mediante el diseño y programación de un videojuego, abordar dichos problemas para conseguir una metodología que sirva de ayuda en este campo. Para ello, se recopilarán estadísticas de uso del videojuego que serán analizadas para determinar las mejoras realizables dentro del propio videojuego. Con estas estadísticas, se realizar a un análisis de los perfiles de los usuarios presentes en el videojuego con el objetivo de saber los distintos tipos de usuarios que hay en función de su nivel de habilidad y en función de su estilo de juego. Todo esto se realizar a con el objetivo de proporcionar una experiencia más gratificante de cara al usuario. De esta forma, se podrán crear mecánicas dinámicas de juego en función de las acciones que hayan realizado cada uno de los usuarios. Finalmente, este trabajo aprovecha esta información para aportar posibles soluciones para mejorar la jugabilidad del propio videojuego y para clasificar a los usuarios en función de la evolución de su perfil utilizando los resultados extraídos del análisis realizado. Para realizar el análisis propuesto se han empleado técnicas de Data Mining no supervisado y series temporales.Video games are the main source of entertainment these days and the most pro table industry that generates audiovisual contents. On the one hand, video game companies consider important to understand their users pro le in order to develop especi c content for them. On the other hand, current users require some arti cial intelligence improvements and gameplay customization to enrich the game experience. In the eld of arti cial intelligence and gameplay customization, there are several video games with dynamic gameplay mechanics that make each game looks like a new and unique experience. The goal of this work, through the design and programming of a video game, is to get a methodology that helps in this eld. To do this, usage video game statistics are collected to be analyzed in order to determine the achievable improvements within the video game itself. With these statistics, an analysis of the users pro les present in the video game is performed in order to know the di erent types of users depending on their skill level and their play style. All this is done with the aim of providing a more rewarding experience for the user. Thus, it can be created dynamic gameplay mechanics based on the actions of each user. Finally, this work uses this information to provide possible solutions to improve the gameplay of the video game and to classify the users according to their pro le evolution by using the results extracted from the previous analysis. To perform the proposed analysis, unsupervised data mining and time-series techniques have been employed
