Neutral meson production and correlation with charged hadrons in pp and Pb-Pb collisions with the ALICE experiment at the LHC

Among the probes used to investigate the properties of the Quark-Gluon Plasma, the measurement of the energy loss of high-energy partons can be used to put constraints on energy-loss models and to ultimately access medium characteristics, such as the energy density or the temperature. The study of two-particle correlations allows us to obtain very different constraints compared to the nuclear modification factor. In particular, the correlation of charged hadrons with high energy $\pi^{0}$ or direct photons is believed to give a measurement of the parton energy loss and insights into the medium-induced modification of the fragmentation process. High energy neutral pions are reconstructed using the ALICE electromagnetic calorimeters EMCal and PHOS, and the charged particles are detected by the main tracking detectors ITS and TPC. In these proceedings, the measurement of neutral mesons at $\sqrt{s} =$2.76 TeV in pp collisions are presented, as well as the measurements of azimuthal $\pi^{0}$-hadron correlations in pp and Pb-Pb collisions at $\sqrt{s_{\rm{NN}}} = 2.76$~TeV, and the extracted per-trigger yield modification factor ($I_{AA}$). Comparisons with theoretical model calculations are also added

Tableaux imaginaires dans un roman de Hugh Hood

Le roman de Hugh Hood, A New Athens , offre un large champ d'enquête à qui s'intéresse à l'inscription du pictural dans la fiction. Le présent article étudie de manière détaillée deux descriptions de tableaux imaginaires et leur fonctionnement dans l'économie du roman. mis en oeuvre par des stratégies et des procédés variés, le jeu avec la linéarité et la spatialité remet en cause l'idée couramment reçue selon laquelle le visuel est synchronique et le verbal diachronique. Dans ce roman d'un écrivain catholique, l'opposition entre mot et image se résout dans un système de signes qui a sa source dans l'Énergie Divine.Hugh Hood's novel A New Athensoffers a fertile field of inquiry for anyone concerned with the intrusion of the pictorial into fiction. The present essay undertakes a detailed examination of two imaginary pictures and their functioning within the economy of the novel. Various strategies and devices enable the narratordescriber and the author to play with lincarity and spatiality, thus undercutting the commonplace notion of the diachronicity of the word and the synchronicity of the image. In this novel by the Roman Catholic Hood, the fundamental opposition between word and image is resolved and merges in the perception of both as signs in a universal system of signification derived from Divine Energy

Instrumentation status of the low-b magnet systems at the Large Hadron Collider (LHC)

The low-beta magnet systems are located in the Large Hadron Collider (LHC) insertion regions around the four interaction points. They are the key elements in the beams focusing/defocusing process allowing proton collisions at luminosity up to 10**34/cm**2s. Those systems are a contribution of the US-LHC Accelerator project. The systems are mainly composed of the quadrupole magnets (triplets), the separation dipoles and their respective electrical feed-boxes (DFBX). The low-beta magnet systems operate in an environment of extreme radiation, high gradient magnetic field and high heat load to the cryogenic system due to the beam dynamic effect. Due to the severe environment, the robustness of the diagnostics is primordial for the operation of the triplets. The hardware commissioning phase of the LHC was completed in February 2010. In the sake of a safer and more user-friendly operation, several consolidations and instrumentation modifications were implemented during this commissioning phase. This paper presents the instrumentation used to optimize the engineering process and operation of the final focusing/defocusing quadrupole magnets for the first years of operation.Comment: 6 pp. ICEC 23 - ICMC 2010 International Cryogenic Engineering Conference 23 - International Cryogenic Materials Conference 2010. 19-23 Jul 2010.

Weyersheim – Lotissement Les Verges

L’opération de diagnostic archéologique, prescrite par le service régional de l’archéologie, dans le cadre de la création d’un lotissement, se situe sur la commune de Weyersheim, à 19 km au nord de Strasbourg. L’emprise diagnostiquée est de 8 200 m2 environ et correspond à des parcelles de vergers et près d’un quartier d’habitations à l’est de la commune. Le diagnostic a révélé la présence d’aménagements sanitaires datés de la Première Guerre mondiale. Aucune autre structure archéologique ni ..

Hésingue – Zone d’activité du Technoport des Trois Frontières (tranche 1)

Le diagnostic n’a révélé aucune structure archéologique. Seuls quelques tessons épars de la protohistoire ont été recueillis dans les niveaux limoneux

Thal-Drulingen – Zac de Thal-Drulingen (tranche 2, phase 1)

Le projet d’aménagement de la Zac de Thal-Drulingen sur une surface de 124 000 m2, a conduit à la réalisation de sondages archéologiques entre le 19 juillet et le 4 août 2016. Le diagnostic n’a livré aucune structure archéologique. Seuls quelques tessons épars de la Protohistoire indéterminée ont été recueillis dans deux tranchées, ainsi qu’un racloir, probablement néolithique, indiquant une présence humaine sporadique
