Optimal contractor for triangle constraint
No full textInternational audienceThis paper presents an optimal method for contracting a triangle Constraints Satisfaction Problem, composed of three distance constraints. Unlike traditional interval analysis methods, this approach takes into account all three constraints globally and focuses on the edges of the CSP boxes, rather than on their entirety, to compute the smallest boxes containing the CSP solution. It is based on constraint propagation, interval analysis tools and some topological properties of the boundary solution of the triangle CSP. This contractor can be applied in various contexts, and in particular to improve localization in robotics
Hommages dans les universitésConstitution d’une base de données sur les doctorats honoris causa en France
No full textAn honorary doctorate is an honorary award given by universities to prominent figures in recognition of their services. In France, it has been awarded since 1918, but there is no complete and consistent inventory across all universities. This dataset fills that gap by listing more than 5,000 awards from around 100 different institutions from 1918 to 2025. Compiled from several sources presented here, it was built on and with the open-access Wikidata knowledge base. Already used on Wikipedia and for educational projects, this inventory is an opportunity for historical and sociological analyses, which are detailed here.Le doctorat honoris causa est une récompense honorifique remise par les universités à des personnalités en remerciements de services rendus. En France, il est remis depuis 1918 sans qu’il existe d’inventaire complet et homogène pour l’ensemble des universités. Ce jeu de données vient compléter ce manque en listant plus de 5000 prix d’une centaine d’établissements différents de 1918 à 2025. Réalisé à travers plusieurs sources ici présentées, il a été construit sur et avec la base de connaissance en libre accès Wikidata. Déjà utilisé sur Wikipédia et pour des projets pédagogiques, cet inventaire ouvre la voie à des analyses historiques et sociologiques qui sont ici détaillées
Building a Peer Review Evaluation Framework for Non-Traditional Research Outputs
No full textInternational audienceThe ATRIUM project aims to create a robust framework for open peer review assessment of non-traditional research outputs to maximise the quality and impact of arts and humanities research in Europe, contributing to research assessment reform. Building on literature review and sources analysis (reports, repositories, and discovery portal classifications such as the SSH Open Marketplace), three sets of evaluation criteria were developed for data papers, workflow papers, and training materials. This poster was presented at the DH 2025 held from July 14-18, 2025, at NOVA-FCSH in Lisbon. This year’s conference focused on the theme ‘Building access and accessibility, open science to all citizens’.
L’archivage du numérique et les dispositifs sociotechniques
No full textInternational audiencen France, depuis les années 2000, les réflexions sur l’archivage définitif du numérique se sont orientées vers la conception de plateformes pour gérer la collecte et la conservation, et se sont focalisées sur l’élaboration de réponses technologiques. La question de la finalité des données, de l’intention qu’elles concrétisent, est passée au second plan. Pourtant, les données sont produites par des systèmes d’information qui transforment des informations brutes en une information compréhensible et partagée par l’intermédiaire d’une modélisation. Ces dispositifs sociotechniques produisent des effets de cadrage. Tout n’y est pas visible, et tout n’est pas visible pour tous et toutes. Un système d’information agit dans un contexte de fonctionnement, à la fois composante cognitive et pratique, qui trie, élimine certaines données, en visibilise d’autres, et dans des conditions d’usage. Par ailleurs, l’humain agit aussi sur la technologie, il l’enrichit, voire la détourne. L’archivistique française prend-elle en compte cette dimension lors de la collecte des données ? La contextualise-t-elle ? Comment les plateformes d’archivage électronique, elles-mêmes des dispositifs sociotechniques forcément rigides, figent-elles les règles d’archivage et réifient-elles les données
Work Participation of Patients Affected by Advanced Cancer: A Scoping Review of Current Knowledge
No full textInternational audienceIntroduction: The increasing survival rates among patients with advanced cancer have brought attention to the issue of work participation for working-age individuals, while current studies predominantly focus on early-stage cancer patients. The objective of this scoping review was to summarize the current knowledge regarding the work participation of patients diagnosed with advanced-stage cancer.Methods: A scoping review was conducted following Mak and Thomas's guidelines and adhering to PRISMA-ScR standards. Three databases (PubMed, Web of Science, and PsycINFO) were systematically searched for articles published up to December 2023. An update was performed in September 2024. We included English and French studies on patients with advanced cancer, aged 18 years and over, with a focus on their work participation. The results are presented according to the arena model, which provides a framework for understanding different dimensions of work participation.Results: Ten studies, primarily focusing on breast cancer, were included after screening 239 records. Key findings revealed that older women and certain ethnic groups face greater challenges in maintaining employment, with treatment side effects such as pain, fatigue, and cognitive impairment having a significant impact on work participation. The research emphasized the need for improved support and information from the healthcare system regarding employment issues.Conclusion: This scoping review addresses the challenges of work participation for patients with advanced cancer, identifying personal, psychological, and workplace barriers. It emphasizes the need for tailored interventions and highlights a significant gap in healthcare professionals' guidance on employment issues. Expanding research beyond breast cancer is essential to improve work participation for this population. The predominance of breast cancer in the current literature underscores the urgent need for broader research that includes a wider range of tumor types and male patients, in order to ensure that work participation strategies are inclusive and equitable
Acquisition pilotée par la donnée pour accélérer la microscopie point-à-point de type Brillouin
No full textInternational audienceWe propose a smart scanning protocol to speed up the acquisition of Brillouin microscopy. It is based on a bimodalimaging system. During a first pass, we use a full-field imaging modality (fluorescence or phase contrast) correlated with Brillouininformation to rapidly provide a global view of the scene. A segmentation of the region of interest of this scene is performed. Thepixels of this region of interest are then acquired with a local Brillouin probe via an online algorithm that auto-adaptively set thetime spent on each of them. We take advantage of recent work on the use of so-called essential pixels identified in the space ofFourier spectral phasors.Nous proposons un protocole de « smart scan », c'est-à-dire une acquisition pilotée par la donnée, pour accélérer l'acquisition de la microscopie Brillouin. Il est basé sur un système d'imagerie bimodale. Dans une première passe, nous utilisons une première modalité d'imagerie plein champ (fluorescence ici) correlée avec l'information Brillouin qui fournit rapidement une vue globale de la scène. Une segmentation de la région d'intérêt de cette scène est réalisée. Les pixels de la région d'intérêt sont ensuite acquis avec une sonde locale de type Brillouin via un algorithme en ligne qui ajuste de façon auto-adaptative le temps passé sur ces pixels. Nous mettons ici à profit des travaux récents sur l'usage des pixels dits essentiels identifiés dans l'espace des phaseurs spectraux de Fourier
Central limit theory for Peaks-over-Threshold partial sums of long memory linear time series
No full textOver the last 30 years, extensive work has been devoted to developing central limit theory for partial sums of subordinated long memory linear time series. A much less studied problem, motivated by questions that are ubiquitous in extreme value theory, is the asymptotic behavior of such partial sums when the subordination mechanism has a threshold depending on sample size, so as to focus on the right tail of the time series. This article substantially extends longstanding asymptotic techniques by allowing the subordination mechanism to depend on the sample size in this way and to grow at a polynomial rate, while permitting the innovation process to have infinite variance. The cornerstone of our theoretical approach is a tailored Lr(P) reduction principle, which enables the use of classical results on partial sums of long memory linear processes. In this way we obtain asymptotic theory for certain Peaks-over-Threshold estimators with deterministic or random thresholds. Applications comprise both the heavy-and light-tailed regimes -yielding unexpected results which, to the best of our knowledge, are new to the literature. A simulation study illustrates the relevance of our findings in finite samples
Comparison of tetrabenazine, tiapride and olanzapine in Huntington’s disease: a one-year French randomized multicenter study (Neuro-HD)
No full textInternational audienceIntroductionChorea and behavioral symptoms in Huntington's disease (HD) have been treated with neuroleptics and related drugs for over 50 years, yet direct randomized comparisons are scarce. This study assessed the efficacy and safety of olanzapine, tetrabenazine, and tiapride in HD, with the Independence Scale as the primary outcome and components of the Unified Huntington's Disease Rating Scale as secondary outcomes.MethodsWe conducted a pragmatic, randomized, open-label trial across 11 centers of the French-Speaking Huntington’s Network, enrolling 179 patients with Huntington’s disease. Participants were randomized into three treatment arms—olanzapine, tiapride, or tetrabenazine—and followed for 52 weeks.ResultsIndependence Scale declined similarly across all treatment arms from baseline to week 52. Chorea improved significantly with both tetrabenazine and olanzapine, whereas rigidity increased only with olanzapine Irritability improved with olanzapine and tiapride, and the total behavioral score improved only with olanzapine. Tetrabenazine was most frequently associated with mood disorders and sedation, while olanzapine caused occasional weight gain and mild increases in LDL and total cholesterol. Discontinuation rates were lowest with olanzapine, with significantly fewer withdrawals dur to depression or suicidal ideation.ConclusionOlanzapine improved chorea, behavior, and irritability, although with a slight increase in rigidity. Tetrabenazine confirmed efficacy for chorea but was associated with mood disorders and drowsiness, while tiapride reduced irritability. These results underscore the importance of symptom-specific, individualized treatment
