The CHIPS Database: A Repository for Reference Data on Chemical Analysis in Archaeometallurgy of Iron
No full textThis preprint presents the core concepts of the CHIPS database, the project of a global repository of reference chemical data related to the archaeometallurgy of iron. Archaeometallurgists interested in iron do not currently have access to extensive chemical reference data repositories. Yet chemical data is of crucial importance both for reconstructing ancient technical systems and economic structures, by determining the operating conditions and the exchange networks. We are seeking to meet this need with the CHIPS database, developed on PostgreSQL. The goal is to provide the scientific community with global reference data in a standardised format. Chemical data can be selected using spatial, chronological or typological queries, thanks to the documentation of archaeological contexts and samples. Particular care has been taken to assess the quality of the chemical data, based on analytical metadata (types of analysis and technical characteristics of the analysers). In order to guarantee the interoperability of the database, the main tables are referenced by libraries, gazetteers and thesauri that are considered as standards by the archaeological community. The data can currently be consulted using a cartographic interface, and the development of a more advanced interface is envisaged, based on the implementation of graphic display tools for chemical data
Représentations et attentes des usagers sur Mon Espace Santé en Île-de-France
No full textINTRODUCTIONMy Health Space, launched in 2022, brings together the Electronic Medical Record, secure messaging, a health diary and a catalog of applications. Although 65.7 million of the French population are affected by it, only 11.5% actively use it. Practitioners showed low adoption of the tool due to its lack of incentive and training, while little data had been collected from the patient perspective. The main objective was to evaluate the representations and expectations of users, the main stakeholders of this tool.METHODOLOGYA qualitative research through 12 semi-structured interviews was conducted in Ile de France. The interviews were transcribed and then analyzed.RESULTSThe analysis revealed 4 themes: knowledge and use of the tool; interest and expectations; opinion; avenues for improvement. Knowledge of the contribution of this tool seems well known, however the lack of communication remains an obstacle to its deployment. The interest in using this platform is undeniable for users, given its ease of use and the functionalities offered such as the centralization of data, monitoring and transmission of medical information. The importance of bilateral use was highlighted in order to have an up-to-date file aimed at improving care. Data protection seems essential, as does respect for medical confidentiality. Among the improvements, a directory of health professionals remains the major point to consider.CONCLUSIONUsers see a certain interest in improving their care, they see themselves becoming an actor in their own health through the management of their medical data. On the other hand, concerns remain about the sustainability of the tool and the security of the data. This device aims to become a real digital health record.INTRODUCTIONMon Espace Santé (MES), lancé en 2022, regroupe le Dossier Médical Partagé, une messagerie sécurisée, un agenda de santé et un catalogue d’applications. Bien que 65,7 millions d’assurés soient concernés par MES, seulement 11,5 % l’utilisent activement. Les médecins ont montré une faible adoption de l’outil en raison de son manque d’incitation et de formation, tandis que peu de données avaient recueilli de la perspective des patients. L’objectif principal était d’évaluer les représentations et attentes des usagers, principaux intéressés de cet outil.MÉTHODEIl s’agit d’une étude qualitative menée auprès de 12 usagers en Ile de France. Les données ont été recueillis grâce à des entretiens semi-dirigés à partir d’un guide d’entretien. Les entretiens ont été retranscris puis analysés. RESULTATSL’analyse a permis de faire ressortir 4 thèmes : connaissances et utilisation de l’outil ; intérêt et attentes ; opinion ; pistes d’amélioration. Les connaissances de l’apport de cet outil semblent bien connues, cependant le manque de communication reste un frein à son déploiement. L’intérêt quant à l’utilisation de cette plateforme est indéniable pour les usagers, étant donné sa simplicité d’utilisation et les fonctionnalités offertes telles que la centralisation des données, le suivi et la transmission des informations médicales. Il a été souligné l’importance d’une utilisation bilatérale afin d’avoir un dossier à jour visant à améliorer la prise en soin. La protection des données semble primordiale au même titre que le respect du secret médical. Parmi les améliorations, un annuaire des professionnels de santé reste le point majeur à envisager.CONCLUSIONLes usagers y voient un intérêt certain dans l’amélioration de leur prise en charge, ils se voient devenir acteur de leur propre santé par la gestion de leurs données médicales. En revanche, des préoccupations subsistent quant à la pérennité de l’outil et la sécurisation des données. Ce dispositif a pour projet de devenir un véritable carnet de santé numérique

A HUMAN-ROBOT INTERACTION PLATFORM FOR INTRAORAL DENTAL SCAN
No full textInternational audienceThis article presents the development and evaluation of a robot-assisted intraoral scanning platform to enhance the precision and repeatability of dental digitization. Intraoral scanners (IOS), a key device in modern restorative dentistry, are highly dependent on practitioner skill, leading to variation in accuracy and increased risk of poorly fitting dental prostheses. A collaborative robot (cobot) is used to mitigate operator variability, reduce musculoskeletal strain and improve educational training. A UR5e cobot equipped with an adaptive gripper and a Dexis IS 3800W IOS was used to digitize a mandibular model, following two occlusal-vestibular-lingual (OVL) scanning pathways and employing two different recording resolutions. Trajectories were generated using SolidWorks and RoboDK software and validated through repeated trials, generating 40 STL files analyzed via Zeiss Inspect software. Metrics such as area of valid distance (AVD), integrated absolute distance (|ID|) and weighted normalized distance (wND) were computed to assess scan quality. In our experimental conditions, high-resolution scans increased surface coverage but did not improve trueness (wND). Initiating scans from the right side improved dimensional precision. Results demonstrate that cobot-assisted scanning can achieve accurate, repeatable digital impressions, offering significant benefits for clinical practice, dental education and telemedicine, particularly in underserved areas. Further trajectory optimization could enhance these outcomes, positioning robotic intraoral scanning as a promising tool in future dental workflows
Modernist Poetry in the Hands of Spies: Poetic Secrecy and the Secret Service
No full textInternational audienceIn Cloak and Gown: Scholars in the Secret War, 1939–1961 (1987), Robin Winks was the first to highlight the remarkable role played by English scholars of poetry—especially from Yale—in American counterintelligence during the OSS era. Formed in June 1942, the Office of Strategic Services (OSS) included Yale professor Norman Holmes Pearson, head of counterintelligence (X-2) in Europe until 1945, and his former student James Jesus Angleton, future head of CIA counterintelligence from 1954 to 1975. These inter- sections between poetry and espionage have drawn growing scholarly attention in the past three decades. Eliot Weinberger, Michael Holzman, and John Kimsey have notably traced how New Critical methods, with their focus on ambiguity, parallel the practices of intelligence analysis. This article explores how such ties between poetic and state secrecy shaped the Modernist canon from the 1940s onward. By looking first into Pearson’s relationship with H.D. (Hilda Doolittle), it spotlights him as a paradoxical figure, positioned at the crossroads between institutional orthodoxy and radical avant-garde. It then suggests that Angleton’s brief but significant relationship with Ezra Pound can give us new insights into both Cold War literary studies and Modernist textuality itself

Differences between men who have sex with men that use drugs and engage in chemsex and those who do not engage in chemsex in the French ANRS-PREVENIR cohort: the need to rethink harm reduction services
No full textInternational audienceBackground: An increasing number of studies are exploring the profiles of men who have sex with men (MSM) in the context of the sexualized use of drugs (chemsex). However, less attention has been paid to MSM who use drugs but do not engage in chemsex. We do not know to what extent the latter are different from the former, or whether they require similar harm reduction services. This study aimed to compare both populations in terms of their sexual risk practices, health, and pre-exposure prophylaxis (PrEP) use.Methods: We used longitudinal data from the ongoing French cohort study ANRS-PREVENIR, which comprises 3076 MSM receiving PrEP. Analyses were conducted on MSM who engaged in chemsex, MSM who used drugs but did not engage in chemsex, and MSM who did not use drugs. Only persons with available data from at least one follow-up visit between M0 and M36 were included, representing 19,375 visits. We built a three-category outcome: (i) MSM who did not use drugs (non-DU), (ii) MSM who used drugs but did not engage in chemsex (DU), and (iii) MSM who engaged in chemsex (CX). A multinomial logistic functional form was used to estimate odds-ratios and 95% confidence intervals, using the DU category as a reference.Results: Among the 2493 cohort participants, at baseline, 62.8%, 22.5%, and 14.6% of the participants were classified in the non-DU, DU, and CX categories, respectively. Compared to DU, non-DU were less likely to (i) declare fisting/BDSM practices, (ii) have a moderately risky sex life, ii) report lifetime PrEP use. Compared to DU, CX also had lower alcohol consumption, and were less likely to have (i) a tertiary education qualification, and (ii) a main partner; in contrast, CX were more likely to be depressed. CX were more likely to report fisting/BDSM practices, but less likely not to use PrEP and to report suboptimal PrEP adherence compared to DU participants.Conclusions: Differences between the DU and CX populations were observed; the latter were more likely to (i) have at-risk sexual practices, (ii) suffer from depression, and (iii) have optimal PrEP adherence. It is essential to provide suitable mental health services to people who engage in chemsex, and to implement tailored sexual health and harm reduction services to MSM who use drugs but who do not engage in chemsex
