Testing M2T/T2M Transformations

Presentado en: 16th International Conference on Model Driven Engineering Languages and Systems (MODELS 2013). Del 29 de septiembre al 4 de octubre. Miami, EEUU.Testing model-to-model (M2M) transformations is becoming a prominent topic in the current Model-driven Engineering landscape. Current approaches for transformation testing, however, assume having explicit model representations for the input domain and for the output domain of the transformation. This excludes other important transformation kinds, such as model-to-text (M2T) and text-to-model (T2M) transformations, from being properly tested since adequate model representations are missing either for the input domain or for the output domain. The contribution of this paper to overcome this gap is extending Tracts, a M2M transformation testing approach, for M2T/T2M transformation testing. The main mechanism we employ for reusing Tracts is to represent text within a generic metamodel. By this, we transform the M2T/T2M transformation specification problems into equivalent M2M transformation specification problems. We demonstrate the applicability of the approach by two examples and present how the approach is implemented for the Eclipse Modeling Framework (EMF). Finally, we apply the approach to evaluate code generation capabilities of several existing UML tools.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech. Proyecto TIN2011-2379

Energy Dependence of the Nernst-Ettingshausen Effect Induced By Pulsed Laser Light in Bismuth Films

The behavior with the irradiation energy and with the magnetic field of the thermomagnetic response induced by laser pulses in 5.5-μm Bi films at room temperature is reported in this paper. The Nernst-Ettingshausen coefficient at an applied magnetic field of 1 T is estimated: QNE≃1.0×10-5 V/T K. A good agreement is found when these results are compared with those reported earlier in polycrystalline bulk samples obtained by a conventional method. This supports the reliability of the pulsed laser technique in the measurement of weak transport effects and indicates that the optically pumped carriers hardly influence the transport properties of bismuth

Characterization of six microsatellite loci in Myrica faya (Myricaceae) and cross amplification in the endangered endemic M. rivas-martinezii in Canary Islands, Spain

Six novel polymorphic microsatellite markers were isolated from enriched libraries in Myrica faya Ait., recently renamed Morella faya, (fayatree, firetree, or firebush) in order to examine the genetic diversity in natural populations. Also, test cross-specific amplification and genetic diversity in Myrica rivas-martinezii, which is endemic on the Canary islands. Microsatellite loci were screened in 225 individuals of both species from different islands of the Canarian archipelago. All markers were successfully amplified from both Myrica species, with an average number of 6.5 and 9.3 alleles per locus in M. rivas-martinezii and M. faya, respectively. There was no evidence for linkage disequilibrium between loci, and the probability of null alleles ranged from 0.01 to 0.17

Design of marteloscope for simulation of silvicultural management of cork oak forest under field conditions

Un marteloscopio es una herramienta didáctica de gran utilidad para el entrenamiento en selvicultura. La disponibilidad de datos reales sobre la masa forestal en dispositivos móviles (tablets) en combinación con un software adecuado permite la retroalimentación directa entre las decisiones selvícolas y los resultados, tanto económicos como ecológicos de las mismas. A través de este Proyecto de Innovación Docente, se ha avanzado en esta línea formativa diseñando e implementando, por primera vez, un marteloscopio en monte alcornocal orientado a la producción de corcho. Como resultado, se ha establecido una parcela permanente de entrenamiento en un alcornocal, que se ha monitorizado de forma exhaustiva, y se ha desarrollado un software nuevo para pc o tablet que simula en tiempo real los efectos de ejercicios de claras selvícolas y de descorches, que el usuario introduce, y que genera salidas instantáneas sobre la producción de corcho obtenida y sus características y sus efectos sobre la masa forestal. Esta simulación facilita el aprendizaje realista de la gestión de alcornocales y la comprensión de los efectos que las decisiones de gestión tomadas tienen sobre los aspectos productivos y ecológicos de la masa forestal.A Marteloscope is an educational tool for silvicultural and forest management training. The availability of actual stand data on mobile devices (tablets) in combination with the appropriate software allows direct feedback among silvicultural decisions and the resulting economic and ecological outcomes. Through this Teaching Innovation Project, we have gone further on this approach by designing and implementing, for the first time, a Marteloscope in a cork oak stand managed for cork production. As a result, we have set up a permanent training plot in the forest, where all trees have been geolocated, measured, both in size and cork production features, marked and also assessed for their ecological value through microhabitat identification approach. We have developed new software for pc or tablets to simulate in real-time silvicultural and cork stripping exercises made by the user, producing instantaneous outputs showing the effects on cork production and forest stand, both currently and after 9 years period (duration of debarking rotation). This simulation facilitates realistic learning of cork oak stands management practices and the understanding of the effects of management decisions on productive and ecological dynamics of forest stand

In vivo anti-inflammatory activity of M116, one extract obtained from the marine bacterium Bacillus amyloliquefaciens

Context: Marine organisms are sources of compounds with anti-inflammatory activity, many of them derived from the secondary metabolites produced by microorganisms. Aims: To evaluate the possible anti-inflammatory effect of M116, an extract obtained by fermentation from the CBM-116 strain of the marine bacterium Bacillus amyloliquefaciens, which was isolated from sediments of the southern coast of the Cuban shelf. Methods: The oral single and repeated different doses of the CBM-116 were evaluated for their ability to ameliorate edema using two in vivo experimental inflammation models: croton oil-induced atrial acute edema and cotton pellets-induced chronic granuloma, both in male Balb/c mice. The systemic production of redox biomarkers after repeated doses in the chronic inflammation model was also tested. Results: A single application of M116 (50-200 mg/kg, 10 mL/kg, p.o.) decreases croton oil-induced acute inflammation in a dose-dependent manner. Single and repeated doses of extract (100-400 mg/kg, p.o.) also were able to inhibit chronic inflammation during both, transudative and proliferative phases of the inflammatory process. This effect was associated with the systemic reduction of oxidative stress. Conclusions: M116 showed anti-inflammatory activity in the context of acute and chronic inflammation associated with its antioxidant mechanisms, which suggest the potential of the marine bacterium Bacillus amyloliquefaciens as a source of new products with biomedical application

Social sciences research in neglected tropical diseases 2: A bibliographic analysis

The official published version of the article can be found at the link below.Background There are strong arguments for social science and interdisciplinary research in the neglected tropical diseases. These diseases represent a rich and dynamic interplay between vector, host, and pathogen which occurs within social, physical and biological contexts. The overwhelming sense, however, is that neglected tropical diseases research is a biomedical endeavour largely excluding the social sciences. The purpose of this review is to provide a baseline for discussing the quantum and nature of the science that is being conducted, and the extent to which the social sciences are a part of that. Methods A bibliographic analysis was conducted of neglected tropical diseases related research papers published over the past 10 years in biomedical and social sciences. The analysis had textual and bibliometric facets, and focussed on chikungunya, dengue, visceral leishmaniasis, and onchocerciasis. Results There is substantial variation in the number of publications associated with each disease. The proportion of the research that is social science based appears remarkably consistent (<4%). A textual analysis, however, reveals a degree of misclassification by the abstracting service where a surprising proportion of the "social sciences" research was pure clinical research. Much of the social sciences research also tends to be "hand maiden" research focused on the implementation of biomedical solutions. Conclusion There is little evidence that scientists pay any attention to the complex social, cultural, biological, and environmental dynamic involved in human pathogenesis. There is little investigator driven social science and a poor presence of interdisciplinary science. The research needs more sophisticated funders and priority setters who are not beguiled by uncritical biomedical promises

Charge separation relative to the reaction plane in Pb-Pb collisions at sNN=2.76\sqrt{s_{\rm NN}}= 2.76 TeV

Measurements of charge dependent azimuthal correlations with the ALICE detector at the LHC are reported for Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV. Two- and three-particle charge-dependent azimuthal correlations in the pseudo-rapidity range $|\eta| < 0.8$ are presented as a function of the collision centrality, particle separation in pseudo-rapidity, and transverse momentum. A clear signal compatible with a charge-dependent separation relative to the reaction plane is observed, which shows little or no collision energy dependence when compared to measurements at RHIC energies. This provides a new insight for understanding the nature of the charge dependent azimuthal correlations observed at RHIC and LHC energies.Comment: 12 pages, 3 captioned figures, authors from page 2 to 6, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/286

Measurements of single top quark production cross sections and |Vtb| in ppbar collisions at sqrt{s}=1.96 TeV

We present measurements of production cross sections of single top quarks in \ppbar collisions at $\sqrt{s}=1.96\;\rm TeV$ in a data sample corresponding to an integrated luminosity of $5.4\;\rm fb^{-1}$ collected by the D0 detector at the Fermilab Tevatron Collider. We select events with an isolated electron or muon, an imbalance in transverse energy, and two, three, or four jets, with one or two of them containing a bottom hadron. We obtain an inclusive cross section of \sigma({\ppbar}{\rargap}tb+X, tqb+X) = 3.43\pm^{0.73}_{0.74}\;\rm pb and use it to extract the CKM matrix element $0.79 < |V_{tb}| \leq 1$ at the 95% C.L. We also measure \sigma({\ppbar}{\rargap}tb+X) = 0.68\pm^{0.38}_{0.35}\;\rm pb and \sigma({\ppbar}{\rargap}tqb+X) = 2.86\pm^{0.69}_{0.63}\;\rm pb when assuming, respectively, $tqb$ and $tb$ production rates as predicted by the standard model.Comment: 11 pages, 8 figures, submitted to Phys.
