Intrinsic backgrounds from Rn and Kr in the XENON100 experiment

2018

In this paper, we describe the XENON100 data analyses used to assess the target-intrinsic background sources radon ([InlineMediaObject not available: see fulltext.]), thoron ([InlineMediaObject not available: see fulltext.]) and krypton ([InlineMediaObject not available: see fulltext.]). We detail the event selections of high-energy alpha particles and decay-specific delayed coincidences. We derive distributions of the individual radionuclides inside the detector and quantify their abundances during the main three science runs of the experiment over a period of ∼4years, from January 2010 to January 2014. We compare our results to external measurements of radon emanation and krypton concentr…

Search for magnetically-induced signatures in the arrival directions of ultra-high-energy cosmic rays measured at the Pierre Auger Observatory

2020

We search for signals of magnetically-induced effects in the arrival directions of ultra-high-energy cosmic rays detected at the Pierre Auger Observatory. We apply two different methods. One is a search for sets of events that show a correlation between their arrival direction and the inverse of their energy, which would be expected if they come from the same point-like source, they have the same electric charge and their deflection is relatively small and coherent. We refer to these sets of events as "multiplets". The second method, called "thrust", is a principal axis analysis aimed to detect the elongated patterns in a region of interest. We study the sensitivity of both methods using a …

Critical proofreading of the book "Les derniers jours du siège d'Alésia"

2023

Was there a lunar eclipse that could have influenced the outcome of the Battle of Alesia? This is the argument developed in the book by Alain Deyber and David Romeuf, «Les Derniers Jours du Siège d'Alésia». Having verified the existence of an eclipse on the date given by the authors and based on the latest publications as well as on the scientific consensus, we conduct a critical study on the chronology of the siege and on the ethnological arguments, even ethno-astronomical of the authors.

Le goût du verbe (I)

2008

Le menu de restaurant est certes un outil pratique permettant au convive de procéder à des choix dans une liste de mets, mais c'est aussi un objet textuel, doté d'une rhétorique spécifique. Il s'agira d'abord, dans cet article, de préciser comment fonctionnent les intitulés de menu.

Rhétorique du menu gastronomique

2009

The elaboration of a restaurant menu as a text aiming at seducing and at convincing visitors, infers that it does not merely enumerates various dishes among which we are to choose from, but that it is a rhetorical production whose processes need to be analysed and whose function needs to be understood. The corpus being studied consists of gourmet menus selected from about twenty fine restaurants. It certainly enables us to observe the main figures of speech (metaphors, metonymies); above all, it reveals the great variety of the rhetorical gear in use : analogies, transgressions, systems of values are as many means of creating the "genuine" flavour of food.

La gastronomie au cœur de la Cité.

2016

International audience; Chercheurs, chefs, professionnels, acteurs publics et industriels s’intéressent dans cet ouvrage à la Cité d’hier, d’aujourd’hui et de demain. À l’heure où le Repas gastronomique des Français est inscrit au patrimoine immatériel de l’UNESCO, la mise en œuvre du réseau des Cités de La gastronomie (Tours, Paris-Rungis, Lyon et Dijon) démontre, une nouvelle fois l’importance du fait alimentaire dans notre culture. Penser l’identité gastronomique demande alors de se libérer d’une tension entre deux visions trop étriquées. Soit à travers une conception de l’identité attachée exclusivement à la tradition, au passé, prise aussi et pétrifiée dans ses racines qui entravent so…
