Digital Fishes - An Interactive Virtual Aquarium

This work is supported by AUIP - Asociación Universitaria Iberoamericana de PostgradoThis work describes the creation of an interactive virtual aquarium, Digital Fishes, with a physical representation in a cubic fish tank with synchronized visual information and animated elements, such as fish and vegetation, which can be used for educational purposes. Here the solution to simulate the movement of marine flora and fauna added to our virtual Aquarium is described. An implementation of the fish behavior, to move in groups using the Boids algorithm, is created, in addition to autonomous behaviors such as chasing prey and fleeing from predators, interactive behaviors such as following the finger on the screen and going towards the food that the user may throw in the pond. The solution described in this work has managed to bring into the hands of children an interactive virtual representation of an interactive as one more learning tool at their disposal. These children who participated in the Digital Fishes Interactive Aquarium's evaluation provided positive feedback, showing great enthusiasm and positively assessed the solution

Scalability of the Muscular Action in a Parametric 3D Model of the Index Finger

A method for scaling the muscle action is proposed and used to achieve a 3D inverse dynamic model of the human finger with all its components scalable. This method is based on scaling the PCSA (physiological cross-sectional area) in a Hill muscle model. Different anthropometric parameters and maximal grip force data have been measured and their correlations have been analysed and used for scaling the PCSA of each muscle. A linear relationship between the normalised PCSA and the product of the length and breadth of the hand has been finally used for scaling, with a slope of 0.01315 cm-2, with the length and breadth of the hand expressed in centimetres. The parametric muscle model has been included in a parametric finger model previously developed by the authors, and it has been validated reproducing the results of an experiment in which subjects from different population groups exerted maximal voluntary forces with their index finger in a controlled postur

Study of the Spanish Federated Sports model of the 21st century

El deporte se ha convertido en uno de los fenómenos sociales y económicos más destacados en la actualidad, con gran repercusión mediática, y seguimiento activo y pasivo. El alto rendimiento deportivo, imagen exterior de muchos países, es una prioridad para las políticas de Estado de los países desarrollados, concibiéndose como un fin de interés general que se debe proteger e incentivar, a través de organizaciones (no lucrativas) con un régimen fiscal favorable, como son las Federaciones Deportivas Españolas. En este trabajo hemos realizado un análisis de la realidad del deporte federado español. Hemos analizado la opinión de personajes claves del deporte español, de los Presidente y Secretario Generales de Federaciones Deportivas Españolas, y la realidad de las cifras económicas que mueve este sector, a través de entrevistas, cuestionarios y análisis de contenido. Los datos revelan un panorama necesario de cambio, donde convendría una revisión de las estructuras del sistema, las fuentes de financiación pública y privada, y la modernización de la gestión federativa.Sport has become a major socio-economic phenomenon of the modern world, with broad media coverage and both active and passive participation. Sporting achievement, the public image of many countries, is one of the main priorities for the governments of developed nations, and represents a goal of general interest that must be preserved and encouraged through (non-profit) organisations that benefit from a favourable tax system, such as the Spanish Sports Federations. In this study, we have undertaken an analysis of the current situation of Spanish federated sport. Using interviews, questionnaires and data analysis, we have examined the opinions of key personalities in Spanish sport, Spanish Sport Federations Presidents and General Secretaries, as well as the financial reality of the sports sector in Spain. The result of our research gives an overview of the present situation where the current model requires a review of its structure and funding sources, public or private, and the modernisation of the federated management model.Estudio financiado por el Consejo Superior de Deportes (EXP. 04/UPB31/08)

Agentes y lazos sociales: la experiencia de volverse comunidad

En la colonia Lomas de Polanco, al sur de la ciudad de Guadalajara, México, entre 1970 y 1990 se generó un movimiento ciudadano, enraizado en las Comunidades Eclesiales de Base y la educación popular, que emprendió una lucha exitosa para conseguir los servicios de infraestructura urbana ante las promesas incumplidas de autoridades y fraccionadores. La confluencia de actores, individuales y colectivos, de distintos contextos, contribuyeron a la reconstitución del tejido social y la creación de los lazos que dieron sentido de comunidad a los colonos y al desarrollo de su capacidad de agencia para la trasformación positiva de su entorno y de su vida. Esta experiencia se recupera en esta obra, a partir de una serie de entrevistas con los actores del movimiento, mediante un análisis retrospectivo y desde varias perspectivas teóricas. Su estudio permite comprender mejor las dinámicas sociales acontecidas y posibilita su reproducción para enfrentar de manera organizada y con éxito problemas en contextos urbanos y sociales particulares.Consejo Nacional de Ciencia y TecnologíaGobierno del Estado de Jalisc

En capítulo II, “Ambiente y su incidencia en los fenómenos organizacionales contemporáneos: un acercamiento desde la contingencia”, el autor señala que los fenómenos organizacionales no son autorreferenciales ni se pueden explicar fuera del entorno en el que se producen. Se continua con el capítulo III “Las ecoaldeas: propuesta de agenda de investigación desde la perspectiva organizacional”, los autores señalan que la importancia del estudio de la ecoaldea radica en que han surgido como una iniciativa de la propia sociedad para buscar soluciones sobre cómo vivir en equilibrio con la naturaleza. En el capítulo IV “Trabajadores del conocimiento y organizaciones informatizadas: los nuevos trabajos de la era en la información”, el autor analiza la emergencia de nuevos empleos derivados del desarrollo del Internet y las tecnologías de la información y la comunicación (TIC) bajo la noción de trabajador del conocimiento, para ello caracteriza algunos de los empleos y las nuevas prácticas laborales que surgen a partir de la incorporación de las TIC en las organizaciones. El capítulo V “Reflexionar y enseñar tecnologías digitales, un primer borrador de una biografía de las cosas”, aquí se señala que las tecnologías digitales son artefactos que tienen una vida social. La línea argumentativa sigue la propuesta de Arjun Appandurai y retoma algunas de las ideas de Igor Kopytoff y John Thompson. El capítulo VI “Escenarios educativos con la integración de TIC. Un análisis organizacional a partir de las interacciones”, habla de que la irrupción de las TIC obliga a las universidades a generar nuevos escenarios en el proceso de formación profesional; las autoras presentan el caso de los simuladores de negocios como medio didáctico y estrategia pedagógica que se despliega en el proceso educativo. el capítulo VII “La intervención en las organizaciones: Apuntes para pensar su importancia” este trabajo es un esfuerzo por conceptualizar lo que es la intervención dentro de las organizaciones, al discutir las diferencias entre la consultoría y la intervención organizacional; además se señala que es importante construir una Teoría general de la intervención organizacional: así como reflexionar en las implicaciones prácticas de la acción interventora en las organizaciones.Elvia Espinosa Infante, coordinador

The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment

The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourteenth from SDSS overall (making this, Data Release Fourteen or DR14). This release makes public data taken by SDSS-IV in its first two years of operation (July 2014-2016). Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey (eBOSS); the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data driven machine learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS website (www.sdss.org) has been updated for this release, and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020, and will be followed by SDSS-V.Comment: SDSS-IV collaboration alphabetical author data release paper.

Measurement of charm production at central rapidity in proton-proton collisions at s=2.76\sqrt{s} = 2.76 TeV

The $p_{\rm T}$-differential production cross sections of the prompt (B feed-down subtracted) charmed mesons D$^0$, D$^+$, and D$^{*+}$ in the rapidity range $|y|<0.5$, and for transverse momentum $1< p_{\rm T} <12$ GeV/$c$, were measured in proton-proton collisions at $\sqrt{s} = 2.76$ TeV with the ALICE detector at the Large Hadron Collider. The analysis exploited the hadronic decays D$^0 \rightarrow$K$\pi$, D$^+ \rightarrow$K$\pi\pi$, D$^{*+} \rightarrow$D$^0\pi$, and their charge conjugates, and was performed on a $L_{\rm int} = 1.1$ nb$^{-1}$ event sample collected in 2011 with a minimum-bias trigger. The total charm production cross section at $\sqrt{s} = 2.76$ TeV and at 7 TeV was evaluated by extrapolating to the full phase space the $p_{\rm T}$-differential production cross sections at $\sqrt{s} = 2.76$ TeV and our previous measurements at $\sqrt{s} = 7$ TeV. The results were compared to existing measurements and to perturbative-QCD calculations. The fraction of cdbar D mesons produced in a vector state was also determined.Comment: 20 pages, 5 captioned figures, 4 tables, authors from page 15, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/307

Epigenetic loss of RNA‑methyltransferase NSUN5 in glioma targets ribosomes to drive stress adaptive translational program

Tumors have aberrant proteomes that often do not match their corresponding transcriptome profiles. One possible cause of this discrepancy is the existence of aberrant RNA modification landscapes in the so-called epitranscriptome. Here, we report that human glioma cells undergo DNA methylation-associated epigenetic silencing of NSUN5, a candidate RNA methyltransferase for 5-methylcytosine. In this setting, NSUN5 exhibits tumor-suppressor characteristics in vivo glioma models. We also found that NSUN5 loss generates an unmethylated status at the C3782 position of 28S rRNA that drives an overall depletion of protein synthesis, and leads to the emergence of an adaptive translational program for survival under conditions of cellular stress. Interestingly, NSUN5 epigenetic inactivation also renders these gliomas sensitive to bioactivatable substrates of the stress-related enzyme NQO1. Most importantly, NSUN5 epigenetic inactivation is a hallmark of glioma patients with long-term survival for this otherwise devastating disease

Perinatal outcomes among immigrant mothers over two periods in a region of central Italy

<p>Abstract</p> <p>Background</p> <p>The number of immigrants has increased in Italy in the last twenty years (7.2% of the Italian population), as have infants of foreign-born parents, but scanty evidence on perinatal outcomes is available. The aim of this study was to investigate whether infants of foreign-born mothers living in Italy have different odds of adverse perinatal outcomes compared to those of native-born mothers, and if such measures changed over two periods.</p> <p>Methods</p> <p>The source of this area-based study was the regional hospital discharge database that records perinatal information on all births in the Lazio region. We analysed 296,739 singleton births born between 1996-1998 and 2006-2008. The exposure variable was the mother's region of birth. We considered five outcomes of perinatal health. We estimated crude and adjusted odds ratios and 95% confidence intervals (CIs) to evaluate the association between mother's region of birth and perinatal outcomes.</p> <p>Results</p> <p>Perinatal outcomes were worse among infants of immigrant compared to Italian mothers, especially for sub-Saharan and west Africans, with the following crude ORs (in 1996-1998 and 2006-2008 respectively): 1.80 (95%CI:1.44-2.28) and 1.95 (95%CI:1.72-2.21) for very preterm births, and 1.32 (95%CI:1.16-1.50) and 1.32 (95%CI:1.25-1.39) for preterm births; 1.18 (95%CI:0.99-1.40) and 1.17 (95%CI:1.03-1.34) for a low Apgar score; 1.22 (95%CI:1.15-1.31) and 1.24 (95%CI:1.17-1.32) for the presence of respiratory diseases; 1.47 (95%CI:1.30-1.66) and 1.45 (95%CI:1.34-1.57) for the need for special or intensive neonatal care/in-hospital deaths; and 1.03 (95%CI:0.93-1.15) and 1.07 (95%CI:1.00-1.15) for congenital malformations. Overall, time did not affect the odds of outcomes differently between immigrant and Italian mothers and most outcomes improved over time among all infants. None of the risk factors considered confounded the associations.</p> <p>Conclusion</p> <p>Our findings suggest that migrant status is a risk factor for adverse perinatal health. Moreover, they suggest that perinatal outcomes improved over time in some immigrant women. This could be due to a general improvement in immigrants' health in the past decade, or it may indicate successful application of policies that increase accessibility to mother-child health services during the periconception and prenatal periods for legal and illegal immigrant women in Italy.</p
