« Vérité sexuelle et mensonge légal. Jouissance et possession dans l’Encyclopédie selon DIDEROT, ou : deviendrons-nous galants, éclairés et heureux? »

2017

International audience; En cherchant la philosophie de l'Encyclopédie dans l'Encyclopédie, que cherche-ton ? Toute encyclopédie demande : que savons-nous, savons-nous seulement ce que nous savons et ce que nous ignorons ? Que pensons-nous, et là encore, le savons-nous ? L'Encyclopédie des Lumières demande plus spécifiquement : en vertu de quoi la lecture d'un « dictionnaire raisonné des sciences, des arts et des métiers », lecture non linéaire à divers titres, décrit-elle pour le lecteur un parcours de « lumières » ? Est-ce d'apprendre ce que nous ignorions ? D'apprendre ce que nous savions sans le savoir ? Est-ce d'apprendre pourquoi et comment nous en sommes venus à savoir ceci ou à pense…

Desymmetrization of Prochiral Cyclobutanones via Nitrogen Insertion: A Concise Route to Chiral γ‐Lactams

2021

Abstract Asymmetric access to γ‐lactams is achieved via a cyclobutanone ring expansion using widely available (1S,2R)‐1‐amino‐2‐indanol for chiral induction. Mechanistic analysis of the key N,O‐ketal rearrangement reveals a Curtin–Hammett scenario, which enables a downstream stereoinduction (up to 88:12 dr) and is corroborated by spectroscopic, crystallographic, and computational studies. In combination with an easy deprotection protocol, this operationally simple sequence allows the synthesis of a range of optically pure γ‐lactams, including those bearing all‐carbon quaternary stereocenters. In addition, the formal synthesis of drug molecules baclofen, brivaracetam, and pregabalin further …

Search for the Decay of the Higgs Boson to Charm Quarks with the ATLAS Experiment

2018

A direct search for the standard model Higgs boson decaying to a pair of charm quarks is presented. Associated production of the Higgs and Z bosons, in the decay mode ZH→ℓ+ℓ−c¯c is studied. A data set with an integrated luminosity of 36.1  fb−1 of pp collisions at √s=13TeV recorded by the ATLAS experiment at the LHC is used. The H→c¯c signature is identified using charm-tagging algorithms. The observed (expected) upper limit on σ(pp→ZH)×B(H→c¯c) is 2.7 (3.9+2.1−1.1) pb at the 95% confidence level for a Higgs boson mass of 125 GeV, while the standard model value is 26 fb.
