Search for jet extinction in the inclusive jet-p(T) spectrum from proton-proton collisions at root s=8 TeV

The first search at the LHC for the extinction of QCD jet production is presented, using data collected with the CMS detector corresponding to an integrated luminosity of 10.7 fb-1 of proton-proton collisions at a center-of-mass energy of 8 TeV. The extinction model studied in this analysis is motivated by the search for signatures of strong gravity at the TeV scale (terascale gravity) and assumes the existence of string couplings in the strong-coupling limit. In this limit, the string model predicts the suppression of all high-transverse-momentum standard model processes, including jet production, beyond a certain energy scale. To test this prediction, the measured transverse-momentum spectrum is compared to the theoretical prediction of the standard model. No significant deficit of events is found at high transverse momentum. A 95% confidence level lower limit of 3.3 TeV is set on the extinction mass scale.

Realismo e impressionismo em contos de Guy de Maupassant

Dans ce texte on a étudié, afin de comprendre et d'analyser les contes réalistes de Guy de Maupassant, comment Erich Auerbach, dans Mimesis (2009), parcourt les sentiers de la littérature occidentale pour dresser un tableau des traits communs qui existent entre les grandes oeuvres réalistes de l'Occident. L'auteur a réalisé des recherches et des commentaires sur les caractéristiques les plus récurrentes du réalisme littéraire dans les oeuvres d'écrivains tels que Homero, Shakespeare, Voltaire, Flaubert, parmi d'autres. Notre recherche vise, dans sa première étape, à présenter, à expliquer ou à identifier dans les contes de Guy de Maupassant, écrivain de la fin du XIXe siècle, les tendances réalistes discutées par ce théoricien et par d'autres au fil du temps, comme, par exemple, Roland Barthes, dans Crítica e verdade (2007), Bersani, dans Le réalisme et la peur du désir (1975) et Philippe Hamon, dans Un discours contraint (1973, p. 411-445). À partir de ces chercheurs, on essaie d'expliciter et d'affirmer le caractère réaliste d'un des maîtres du récit court - sûrement un représentant du réalisme parmi les grands écrivains de cet art - car dans Mimesis (2009) Zola est considéré par Auerbach comme le dernier des grands réalistes français. En plus, pour la deuxième partie de ce travail, on a l'intention de traiter l'émergence de l'impressionnisme artistique en France, et de présenter les concepts et les thèmes qui ont influencé ce mouvement et se présentent dans la construction des récits de Maupassant. Pour le faire, O impressionismo (1962) de Balzi, O impressionismo (1965) de Serullaz, Impressionniste et symboliste devant la presse (1959) de Jacques Lethève, Impressionismo (2010) de Lobstein e autres, mentionnés dans la bibliographie de cette recherche, ont ouvert la voie aux analyses...

Fishes from Baía da Medalha, southern Pantanal, Brazil: A 20 years review

Located in the Pantanal of Miranda-Abobral, the Baía da Medalha is the largest pond close to the Base de Estudos do Pantanal of the Universidade Federal de Mato Grosso do Sul. The Baía da Medalha has been a study site for several didactic and scientific projects for years. Nevertheless, its fish fauna has never been inventoried. Based on data collected from the beginning of the 1990s up to 2011, we provide a list of fish species from the Baía da Medalha. A total of 97 species were recorded, corresponding to about 40% of the species stated for the Pantanal. Characiformes and Siluriformes were the most species-rich orders, being Characidae and Cichlidae the families with the highest number of species. Regional seasonal flood dynamics and the abundance of aquatic macrophytes may be associated with this high diversity. The representative richness found in this lagoon highlights the importance of such taxonomic surveys to preserve the diversity of aquatic habitats within the Pantanal ecosystem.
