"Cypriot juglet theory": a review
No full textThe paper has been reviewed by F. Antolin, co-editor of the blog.https://opiumpoppy.hypotheses.orgThe aim of this article is to review the hypothesis that jugs made in Cyprus were used in the opium trade at the end of the Bronze Age (1650-1350 BCE) in the eastern Mediterranean. It reviews the original article by R.S. Merrillees (1962) and its scientific implications especially results of chimical analyses (ORA) that have been performed on archaeological vessels to test this hypothesis.L'objectif de cet article est de revoir l'hypothèse selon laquelle des cruchettes fabriquées à Chypre ont été utilisées pour le commerce de l'opium à la fin de l'âge du Bronze (1650-1350 avant J.-C.) en Méditerranée orientale. Il passe en revue l'article original de R.S. Merrillees (1962) et ses implications scientifiques, en particulier les résultats des analyses chimiques (ORA) qui ont été effectuées sur des récipients archéologiques pour vérifier cette hypothèse

: Patient expertise, peer health mediators and peer helpers
No full textInternational audienceC’est dans le prolongement du courant du rétablissement (recovery) instauré à la fin des années 1980 dans une dynamique interactive avec les professionnels de santé et de déstigmatisation auprès des populations que sont apparus les pairs-aidants professionnalisés, aussi appelés médiateurs de santé-pairs. Ce mouvement s’inscrit dans une mutation sociétale qui dépasse la santé mentale puisque le savoir des malades a été reconnu au cours de la dernière décennie comme un fait social [1-4] tel que décrit par Émile Durkheim [5], le père de la sociologie.Un mouvement de société souligné par le British Medical Journal, une revue d’evidence based medicine (médecine par les preuves), en 2013, à travers un éditorial qui demandait que la communauté scientifique et les praticiens laissent “la révolution des patients commencer” [6] tout en donnant l’exemple avec l’intégration de patients évaluateurs au sein de la revue et de son comité éditorial. C’est à partir de ce contexte global que se sont développées en France diverses formes d’interactions entre les savoirs expérientiels acquis à l’épreuve de troubles psychiques,de la vie, et les savoirs basés sur la science de ces mêmes troubles qui sont, eux, largement détenus par les professionnels de santé et du médico-social
4500 years of morphological diversification in Western Europe wild boars (Sus scrofa) and the consequences of the Neolithic transition
No full textInternational audienceEvolutionary biologists have recently solicited archaeologists to help document and understand the morphological evolution of animals in response to human activities and, more generally, to help reconstruct the history and significance of the anthropogenic impact on worldwide ecosystems. Artificial selection associated with domestication is the best-known example of a major anthropogenic morphological evolution preserved in the archaeological record. However, the impact of the domesti-cation process and dispersal on the morphological evolution of animals has been far less explored. To fill this gap, we focused on 4500 years of evolution in Western Europe Sus scrofa, covering the Neolithic transition ‒ a major anthropogenic ecological disturbance involving landscape modification and the translocation of domestic mammals. Using geometric morphometrics on key phenotypic markers preserved in the archaeological record, associated with isotopic studies, we explored how, and in response to which cultural drivers, the Neolithic niche construction has influenced the morphological evolution ofWestern European wild boars (Sus scrofa scrofa). The decoupling of size and shape components from bone morphological variation has facilitated the identification of several processes of phenotypic diversification of Sus s. scrofa in response to human behaviour during the Neolithic transition in Western Europe
Search for pairs of muons with small displacements in collisions at TeV with the ATLAS detector
No full textInternational audienceA search for pairs of opposite electrically charged muons with impact parameters in the millimetre range is presented, using 139 fb of TeV collision data from the ATLAS detector at the LHC. The search targets the gap in coverage between existing searches for leptons with large displacement and prompt leptons. No significant excess over the background expectation is observed and exclusion limits are set on the mass of long-lived scalar supersymmetric muon-partners (smuons) with much lower lifetimes than previously targeted by displaced muon searches. Smuon lifetimes down to 1 ps are excluded for a smuon mass of 100 GeV, and smuon masses up to 520 GeV are excluded for a proper lifetime of 10 ps, at 95% confidence level. Finally, model-independent limits are set on the contribution from new phenomena to the signal-region yields
Search in diphoton and dielectron final states for displaced production of Higgs or bosons with the ATLAS detector in TeV collisions
No full textInternational audienceA search is presented for displaced production of Higgs bosons or bosons, originating from the decay of a neutral long-lived particle (LLP) and reconstructed in the decay modes and . The analysis uses the full Run 2 data set of protonproton collisions delivered by the LHC at an energy of TeV between 2015 and 2018 and recorded by the ATLAS detector, corresponding to an integrated luminosity of 139 fb. Exploiting the capabilities of the ATLAS liquid argon calorimeter to precisely measure the arrival times and trajectories of electromagnetic objects, the analysis searches for the signature of pairs of photons or electrons which arise from a common displaced vertex and which arrive after some delay at the calorimeter. The results are interpreted in a gauge-mediated supersymmetry breaking model with pair-produced higgsinos that decay to LLPs, and each LLP subsequently decays into either a Higgs boson or a boson. The final state includes at least two particles that escape direct detection, giving rise to missing transverse momentum. No significant excess is observed above the background expectation. The results are used to set upper limits on the cross section for higgsino pair production, up to a mass of 369 (704) GeV for decays with 100% branching ratio of to Higgs () bosons for a lifetime of 2 ns. A model-independent limit is also set on the production of pairs of photons or electrons with a significant delay in arrival at the calorimeter
