Extending the search for neutrino point sources with iceCube above the horizon
2009
Point source searches with the IceCube neutrino telescope have been restricted to one hemisphere, due to the exclusive selection of upward going events as a way of rejecting the atmospheric muon background. We show that the region above the horizon can be included by suppressing the background through energy-sensitive cuts. This approach improves the sensitivity above PeV energies, previously not accessible for declinations of more than a few degrees below the horizon due to the absorption of neutrinos in Earth. We present results based on data collected with 22 strings of IceCube, extending its field of view and energy reach for point source searches. No significant excess above the atmosp…
Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei
2008
Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the ighest-energies, which are correlated with the positions of relatively nearby active galactic nuclei (AGN) [Pierre Auger Collaboration, Science 318 (2007) 938]. The correlation has maximum significance for cosmic rays with energy greater than ~6 x 1019 eV and AGN at a distance less than ~75 Mpc. We have confirmed the anisotropy at a confidence level of more than 99% through a test with parameters specified a priori, using an independent data set. The observed correlation is compatible with the hypothesis that cosmic rays with the highest-energies originate fro…
Soins ambulatoires et facteurs associés à la réhospitalisation précoce des sujets âgés (65+) après un infarctus du myocarde : étude observationnelle …
2017
Etat de la question Les rehospitalisations precoces (RHP), dans les 30 jours suivant la sortie d’hospitalisation, sont frequentes chez les sujets âges, notamment apres un infarctus du myocarde (IDM). Elles augmentent la morbi-mortalite et les depenses de sante. Il a ete demontre qu’une meilleure organisation de la sortie d’hospitalisation reduit significativement le risque de RHP. Neanmoins, il n’existe aucune recommandation sur le suivi ambulatoire en sortie d’hospitalisation. L’objectif de l’etude etait d’analyser les soins ambulatoires post-hospitaliers et les facteurs associes a la RHP des sujets âges apres un IDM. Materiel et methodes Etude observationnelle retrospective a partir des d…
Fouille d’un quartier funéraire des Ier et IIe s. dans le suburbium de Soissons/Augusta Suessionum : aires de crémation et inhumations d’enfants
2012
In the beginning of 2008 a preventive excavation has been conducted on about 1200 m2 of a large antique cemetery situated upon the butte Saint-Jean at Soissons (Aisne). In this cemetery, almost unknown, located south-west of the Roman town Augusta Suessionum a consistent activity in the part being excavated took place between the Augustan era and mid 2nd c. The total number of inhumations uncovered is 186 (mainly of infants). Cremations were executed from the very beginning altogether with inhumations, in more or less close proximity to them according to periods, then became predominant to the detriment of burials which were just previously arranged. Different structures clearly connected t…

VLBA polarimetric monitoring of 3C 111
2018
Context. While studies of large samples of jets of active galactic nuclei (AGN) are important in order to establish a global picture, dedicated single-source studies are an invaluable tool for probing crucial processes within jets on parsec scales. These processes involve in particular the formation and geometry of the jet magnetic field as well as the flow itself. Aims. We aim to better understand the dynamics within relativistic magneto-hydrodynamical flows in the extreme environment and close vicinity of supermassive black holes. Methods. We analyze the peculiar radio galaxy 3C 111, for which long-Term polarimetric observations are available. We make use of the high spatial resolution of…
Growing a Project-Based Translation Pedagogy: A Fractal Perspective
2012
Le présent article propose un cheminement fractal à travers la psychologie et la philosophie éducative, avec l’intention de faire la lumière sur une représentation arborescente de sources d’inspiration interdisciplinaires et complémentaires pour une pédagogie de la traduction par projets. Commençant par la méthode d’apprentissage socioconstructiviste proposée au tournant du millénaire, notre propos tente de brosser un vaste portrait des influences synergiques sous-jacentes à l’approche émergente « holistique-expérientielle » de la formation en traduction. Le post-modernisme, l’énaction dans les sciences cognitives, la théorie de la complexité, la théorie éducative transformationnelle et l’é…
