1. « L’écriture de soi, une pratique intersubjective et relationnelle »

Author: Godard, Anne, Godard, Anne, and Anne Godard
Subjects: [SHS.LITT] Humanities and Social Sciences/Literature, écriture relationnelle, [SHS.EDU] Humanities and Social Sciences/Education, sujet, Autobiographie, réflexivité, écriture de soi, intersubjectivité, [SHS.LANGUE] Humanities and Social Sciences/Linguistics
Abstract: L’introduction présente un cadrage théorique autour de l’écriture comme pratique de subjectivation et d’invention de soi (Foucault) nécessitant un dispositif performatif qui dépasse la seule narration (Butler). L’écriture de soi s’y fait à la fois enquête et opération de resaisie de soi, dans l’énonciation en première personne. Cette pratique se légitime dans différents contextes de création, de recherche et de formation, et dans des formes discursives variées qui mettent en scène la construction intersubjective et relationnelle du sujet.

Abstract: International audience; Background The identification of patients at high risk of a disabling disease course would be invaluable in guiding initial therapy in Crohn’s disease (CD). Our objective was to evaluate a combination of clinical, serological, and genetic factors to predict complicated disease course in pediatric-onset CD. Methods Data for pediatric-onset CD patients, diagnosed before 17 years of age between 1988 and 2004 and followed more than 5 years, were extracted from the population-based EPIMAD registry. The main outcome was defined by the occurrence of complicated behavior (stricturing or penetrating) and/or intestinal resection within the 5 years following diagnosis. Lasso logistic regression models were used to build a predictive model based on clinical data at diagnosis, serological data (ASCA, pANCA, anti-OmpC, anti-Cbir1, anti-Fla2, anti-Flax), and 369 candidate single nucleotide polymorphisms. Results In total, 156 children with an inflammatory (B1) disease at diagnosis were included. Among them, 35% (n = 54) progressed to a complicated behavior or an intestinal resection within the 5 years following diagnosis. The best predictive model (PREDICT-EPIMAD) included the location at diagnosis, pANCA, and 6 single nucleotide polymorphisms. This model showed good discrimination and good calibration, with an area under the curve of 0.80 after correction for optimism bias (sensitivity, 79%, specificity, 74%, positive predictive value, 61%, negative predictive value, 87%). Decision curve analysis confirmed the clinical utility of the model. Conclusions A combination of clinical, serotypic, and genotypic variables can predict disease progression in this population-based pediatric-onset CD cohort. Independent validation is needed before it can be used in clinical practice.

4. Les ateliers du sujet : approches pluridisciplinaires des écritures de soi

Author: Anne Godard and Godard, Anne
Subjects: [SHS.LITT] Humanities and Social Sciences/Literature, écriture relationnelle, [SHS.EDU] Humanities and Social Sciences/Education, sujet, Autobiographie, réflexivité, écriture de soi, intersubjectivité, [SHS.LANGUE] Humanities and Social Sciences/Linguistics
Abstract: « Écrire sur soi, c’est écrire sur les autres » (Doubrovsky, 2011)Portées par un « je » qui ne se réduit pas au « moi », l’écriture de soi est toujours à la fois intersubjective et relationnelle. À travers des exemples allant de l’autofiction littéraire aux écrits numériques, de l’ethnologie aux écrits réflexifs de formation et aux ateliers d’écriture créative, cet ouvrage, fruit d’un séminaire interdisciplinaire, en éclaire le potentiel de connaissance et d’émancipation dans la création, les sciences humaines, l’enseignement et la formation. Abordant l’écriture de soi comme instrument de connaissance et de construction subjective, ce volume collectif, issu d’un séminaire pluridisciplinaire de l’équipe de Didactique des langues, des textes et des cultures (DILTEC-EA 2288), en éclaire les modalités et les contraintes, et en cerne les formes discursives et les visées éthiques. À partir d’études appartenant aux domaines de la création littéraire, de la recherche en sciences humaines, de la formation professionnelle et de l’enseignement de langues, l’ouvrage montre que le projet de rendre compte de soi par l’écriture ne se réduit ni à l’expression ni au récit de soi, notamment par ses dimensions intersubjectives et relationnelles. Portées par un « je » qui ne se réduit pas au « moi », les différentes écritures de soi – littéraires, scientifiques et formatives – situent le sujet à la fois dans une relation interlocutive et dans une communauté d’interprétation. Ce faisant, elles associent, dans leur mouvement réflexif, l’investigation, l’expérimentation et l’émancipation.Avec des contributions de : Violaine Bigot, Nathalie Borgé, Isabelle Cros, Nadja Maillard-De La Corte Gomez, Anne Godard, Cécile Leguy, Muriel Molinié, Olivier Lumbroso et Donatienne Woerly

Abstract: HIV-1 post-treatment controllers are rare individuals controlling HIV-1 infection for years after antiretroviral therapy interruption. Identification of immune correlates of control in post-treatment controllers could aid in designing effective HIV-1 vaccine and remission strategies. Here, we perform comprehensive immunoprofiling of the humoral response to HIV-1 in long-term post-treatment controllers. Global multivariate analyses combining clinico-virological and humoral immune data reveal distinct profiles in post-treatment controllers experiencing transient viremic episodes off therapy compared to those stably aviremic. Virally-exposed post-treatment controllers display stronger HIV-1 humoral responses, and develop more frequently Env-specific memory B cells and cross-neutralizing antibodies. Both are linked to short viremic exposures, which are also accompanied by an increase in blood atypical memory B cells and activated subsets of circulating follicular helper T cells. Still, most humoral immune variables only correlate with Th2-like circulating follicular helper T cells. Thus, post-treatment controllers form a heterogeneous group with two distinct viral behaviours and associated immune signatures. Post-treatment controllers stably aviremic present “silent” humoral profiles, while those virally-exposed develop functionally robust HIV-specific B-cell and antibody responses, which may participate in controlling infection.

Abstract: International audience; The introduction to this collective volume on writing between languages outlines a theoretical framework for literary plurilingualism, specially focusing on translated heterolingual works, and more broadly for plurilingual creativity in teaching and research. We present the aims of the book, which is protean in the diversity of its contributions, as much from its multidisciplinarity, the scientific backgrounds of its contributors, as from their writing and style. Adopting a processual approach, we highlight some of the creative dynamics of research between the disciplines involved in order to shed light on plurilingual creation in Francophone spaces, with a special interest in Indigenous languages.; L’introduction de ce volume collectif sur l’écriture entre les langues esquisse un cadrage théorique autour du plurilinguisme littéraire, notamment dans le cadre d’œuvres hétérolingues traduites, et plus largement de la créativité plurilingue en contexte d’enseignement et de recherche. Nous y présentons les visées de l’ouvrage, protéiforme dans ses contributions, tant par l’ancrage disciplinaire, par les cultures scientifiques des auteurs, que par les écritures et le style. Dans une approche processuelle, nous mettons en lumière quelques-unes des dynamiques créatives de recherche entre les disciplines impliquées pour éclairer la création plurilingue dans les espaces francophones, avec une ouverture aux langues autochtones.

7. In situ 14C-10Be disequilibrium suggests a recent and major denudation event of French Massif Central, despite slow tectonic deformation

Abstract: Geomorphologists classically compute denudation rates from in situ cosmogenic 10Be concentrations. A major assumption is that denudation rates remain steady during the 10Be integration time scale. But early 14C-10Be data we presented last year at this conference suggested that this is hardly tested in environments slowly deformed by tectonics, with integration time covering thousands of years, and erosion rates from 10 to 100 mm/ky.Here, we extended our 14C-10Be dataset to test recent and substantial shifts in denudation. 14C is more sensitive than 10Be to recent and short-term changes in denudation, because of a shorter half-life (5,700 y versus 1.4 My). Studies (Hippe, 2017; Mudd, 2017; Skov et al., 2019; Hippe et al., 2021) have discussed this application of coupled 14C - 10Be measurements.We carried out in situ 14C measurements on river sand which has available 10Be date (Desormeaux et Al., 2021). The studied mountain range is called Massif Central and is west of the European Alp foreland, in southern France. Elevation is ~700 m on average, with an elevated low-relief surface and a steep escarpment along the Cevennes Fault bordering the Alp foreland. The area has a homogeneous lithology rich in quartz. Past glaciations were of limited extent. There is little space for sediment storage, thin soils, no dams, and presently limited anthropic activity. Massif Central is only impacted by slow tectonic deformation. Landslides are very rare but erosion processes are active.Our new 14C results combined with Desormeaux et al., 2021's 10Be data confirm the substantial 14C-10Be disequilibrium. 14C apparent denudation rates are several times higher than 10Be denudation rates. We explore four end-members which could explain such a disequilibrium. This exploration suggests that only major and recent events in denudation could produce such a disequilibrium, and that the landscape we presently see is rather transient than steady.

Abstract: Detrital 10Be from continental river sands or submarine sediments has been extensively used to determine the average long-term denudation rates of terrestrial catchments, based on the assumption that the rate of cosmogenic nuclide production by the interaction of source rocks with cosmic radiation balances out the loss of these nuclides by surface denudation. However, the 10Be signal recorded in sediments may be affected at the source by the response time of mountainous catchments to high-frequency forcings. In addition, transient sediment storage in piedmonts, alluvial plains and lakes or near the coast may also induce a difference between the erosive signal and its record in the sedimentary sink. Consequently, a significant part of the signal recorded in shallow-water sediments can be lost, as deep marine sediments may simultaneously record a signal coming from newly eroded source rocks along with one coming from the destabilization of previously deposited sediments. In this paper, we use the landscape evolution model Badlands to simulate erosion, deposition and detrital 10Be transfer from a source-to-sink sedimentary system (the Var River catchment, southern French Alps) over the last 100 kyr. We first compare model-based denudation rates with the ones that would be extracted from the 10Be record of local continental sediments (equivalent to river sands) and from sediments deposited offshore over time in order to examine if this record provides an accurate estimate of continental denudation rates. Then, we examine which conditions (precipitation rate, flexure, ice cover) satisfy published measured river incision rates and 10Be concentration in submarine sediments. Our results, based on the Var catchment cosmic ray exposure dating and modelling indicate that, while river sands do accurately estimate the average denudation rate of continental catchments, this is much less the case for deep submarine sediments. We find that deep-sea sediments have a different and often much smoother 10Be signature than continental ones and record a significant time lag with respect to imposed precipitation rate changes, representing the geomorphological response of the margin. A model which allows us to fit both measured 10Be concentration in marine sediments and river incision rates on land involves an increase in precipitation rates from 0.3 to 0.7 m yr−1 after 20 ka, suggesting more intense precipitation starting at the end of the Last Glacial Maximum.

Abstract: International audience; The old-age security motive for fertility postulates that people’s needs for old-age support raise the demand for children. We exploit the extension of social pensions in Namibia during the 1990s to provide a quasi-experimental quantification of this widespread idea. The reform eliminated inequalities in pension coverage and benefits across regions and ethnic groups. Combining differences in pre-reform pensions and differences in exposure across cohorts, we show that pensions substantially reduce fertility, especially in late reproductive life. The results suggest that improving social protection for the elderly could go a long way in fostering fertility decline in sub-Saharan Africa. (JEL H55, I38, J13, J14, O15)

Abstract: International audience; ObjectifsDes demandes d’euthanasie ou de suicide assisté sont parfois exprimées par des patients en fin de vie. Notre recherche avait pour objectif d’analyser l’évolution de ces demandes.Patients, matériels et méthodesCette étude de cohorte prospective, d’une durée d’un an, menée auprès des professionnels de santé salariés et libéraux d’une région française se base sur le remplissage de trois questionnaires au cours d’une semaine suivant la formulation d’une demande d’euthanasie ou de suicide assisté de la part de patients en fin de vie.RésultatsCinquante-cinq demandes ont pu être analysées. Une semaine après la formulation initiale, vingt-trois patients ont réitéré leur demande, 22 ne l’ont pas fait et 10 patients sont décédés. Pour les 23 demandes réitérées, les professionnels rapportent le désespoir des patients face à leur situation. Concernant les 22 demandes non réitérées, les professionnels déclarent majoritairement ne pas avoir abordé à nouveau le sujet et un sentiment de résignation chez les patients, quand d’autres professionnels décrivent des patients percevant un espoir dans leur avenir.ConclusionLes résultats montrent une difficulté dans le cadre de la relation thérapeutique d’engager une discussion suite à la formulation d’une demande d’euthanasie ou de suicide assisté. L’écoute de ces demandes est exigeante, en ce sens la formation des soignants à la démarche éthique dans l’accompagnement de la fin de la vie mérite d’être encouragée. En offrant des repères et des outils aux professionnels, l’inconfort serait réduit et donnerait l’occasion aux patients de s’exprimer plus librement et aux professionnels de santé d’explorer les besoins en fin de vie de leurs patients.

Abstract: International audience; Pharmacists are both drug experts and community health professionals. These characteristics make them potentially key resources in the organization of palliative care at home. However, their role with patients at the end of life, their family and friends, and other healthcare professionals has not yet been described and remains largely unknown in France. Our study aims to assess whether pharmacists recognize a role for themselves in end-of-life care at home. The methodology was qualitative, based on semi-structured interviews. The pharmacists included were distributed in the Auvergne-Rhône-Alpes region, in rural, urban and semi-urban areas, with 26 interviews conducted to achieve data sufficiency. Participants were asked to recall a recent palliative situation with their associated role. The results indicate a difficult awareness despite a concrete role in patient care. Cancers are the diseases most often identified as requiring significant support.; Les pharmaciens d’officine sont à la fois des experts du médicament et des professionnels de santé de proximité. Ces caractéristiques en font des ressources potentiellement clés dans l’organisation des soins palliatifs à domicile. Toutefois, leur rôle auprès des patients en fin de vie, de leur entourage ou des autres professionnels de santé n’a pas encore été décrit et reste largement méconnu en France. Notre étude vise à évaluer si les pharmaciens d’officine se reconnaissent un rôle dans l’accompagnement de la fin de vie à domicile. La méthodologie est qualitative, à partir d’entretiens semi-dirigés. Les pharmaciens inclus étaient répartis en région Auvergne-Rhône-Alpes, en zones rurale, urbaine et semi-urbaine. Vingt-six entretiens ont été réalisés pour atteindre une suffisance des données. Les participants devaient se souvenir une situation palliative récente avec leur rôle associé. Les résultats indiquent une prise de conscience laborieuse malgré un rôle pourtant concret de prises en charge de patients. Les cancers sont les maladies les plus souvent identifiées comme nécessitant un accompagnement conséquent.

We study a particular case of vortex collapses called "mono-scale collapses" and this study gives the hölder regularity for the 3-vortex problem under standard non-degeneracy assumption. In a last part, we improve a previous result concerning the improbability of vortex collapses for the quasi-geostrophic model., Dans cet article nous étudions les systèmes de points-vortex quasi-géostrophiques dans un cadre très général appelé les points-vortex alpha. Nous étudions un cas particulier de collisions de vortex appelées "collisions mono-échelles" et cette étude nous donne la régularité Höldérienne du problème à 3 vortex sous des hypothèses standards de non-dégénérescence. Dans une dernière partie, nous améliorons un précédent résultat sur l'improbabilité des collisions de vortex pour le modèle quasi-géostrophique.

Abstract: International audience; With an operating Atacama Large Millimeter Array telescope and the recently launchedJames Webb Space Telescope, astronomy enters its golden age. Physical conditions of the interstellar medium (ISM) are derived from molecular spectra. The interpretation of these spectra requires to know the population of energy levels of the chemical species. However, most of the astrophysical media do not fulfill local thermodynamic equilibrium conditions. are determined by taking into account both radiative, characterized by Einstein coefficients, and collisonal, characterized by rate coefficients, transitions. Nowadays, the rate coefficients, which are system-specific, can only be computed for ”small” molecules colliding with light partners. However, in media like cometary or planetary atmospheres, the dominant colliders are ”big” molecules, such as H2O, CO, etc. Our understanding of the chemical composition of the universe is limited by computer power. Therefore, numerical strategies need to be elaborated to compute accurate rate coefficients for ”big” collisional systems. In this work, limitations and strategies that can be put into place to treat colliding systems involving H2O will be presented through the example of CS-H2O and HCN-H2O. This study starts by quantum calculations in order to reach convergence for as many transitions as possible. The approaches used are the ”exact” Close-Coupling method, that will be then supported with Coupled-State or infinite order sudden approximations. In a second part, collisional data are computed with statistical methods. The accuracy of the results obtained with the different methods will be evaluated by a comparison with the results obtained with quantum calculations

Abstract: Citation suggérée : Anses. (2022). Fibres courtes d’amiante et autres particules minérales allongées de moins de 5 micromètres de longueur. Mises à jour des données sanitaires et d’exposition. (saisine 2019-SA-0044). Maisons-Alfort : Anses, 124 p.; L’Anses a été saisie en mars 2019 par la Direction Générale de la Santé (DGS) pour réaliser une mise à jour des données sanitaires (épidémiologiques et toxicologiques) et d’exposition aux fibres courtes d’amiante (FCA). Cette demande fait suite à la publication en 2009 d’une première expertise sur le sujet, concluant, sur la base des données disponibles, qu’il n’était pas possible d’écarter avec certitude l’existence de propriétés cancérogènes des FCA (Anses, 2009a). Dans l’hypothèse d’une toxicité des FCA, elle serait certainement inférieure à celle des fibres longues. Les données acquises lors de cette expertise concernant la distribution granulométrique des fibres d’amiante, que ce soit pour l’environnement général, professionnel ou à proximité d’affleurements naturels, soulignent la prépondérance des FCA associées à des concentrations élevées. Ces conclusions étaient fondées sur une analyse documentaireapprofondie et une collecte de données sur la distribution granulométrique des fibres d’amiante dans divers environnements, tels que les espaces intérieurs et extérieurs, et dans le milieu professionnel. Depuis la publication de ce rapport, la toxicité des FCA est encore en discussion dans la communauté scientifique et de nouvelles études visant à renforcer les connaissances ont été conduites. Sur le volet « exposition » en particulier, la DGS a commandé en 2011 au Laboratoire Amiante Fibres et Particules (LAFP) de la Ville de Paris une étude dont l’objectif était d’évaluer les empoussièrements en fibres d’amiante générés lors de la mise en œuvre de nettoyage de dalles de sol en vinyle amiante (DVA) dans un collègeet un hôpital. Des niveaux significatifs ayant été relevés sur certains points de mesure, une étude complémentaire a été engagée pour confirmer les résultats dans d’autres locaux. Les concentrations en FCA mesurées dans cette seconde étude sont moins élevées et hétérogènes (entre 1 et 75 FCA/L), sans qu’aucune corrélation avec des fibres d’amiante de longueur supérieure à 5 μm n’ait pu être établie.

Abstract: International audience; In this paper we present the results of the national French project SolDuGri dealing with pavement reinforcement by glass fiber grids. In this project, an accelerated pavements test (APT) was performed on 6 pavement sections to evaluate the in situ performance of the reinforcement on their lifetime. The tests consisted in building test sections with four different types of grids, and two different compacted asphalt con-crete layers above (hot mix asphalt and warm mix asphalt). A total number of 2.2 mil-lion of 65 kN dual wheel loads was applied on these pavement sections and their per-formance was evaluated using in situ instrumentation, pavement monitoring tests and laboratory tests on recovered specimens. In parallel and in addition to static debond-ing tests, four points bending (4PB) fatigue tests were carried out in the laboratory on reinforced and non-reinforced beams. Two reference glass fiber grids were used, one with a high tensile strength of 100 kN/m and one with a lower tensile strength of 50 kN/m. Laboratory fatigue tests were performed with 2 positions of the rein-forcement in the beams to evaluate the effect of reinforcement for any position of the grid in the beam. Based on the results of the 4PB fatigue tests, a methodology is proposed to evaluate the lifetime of the full-scale test sections, and the predictions are compared with the results of the APT experiment showing good agreement.

Abstract: International audience; Controlling the stoichiometry of supported bimetallic nanoparticles is essential in many catalytic reactions, notably selective CO2 hydrogenation. Thus, a new strategy to ensure the preferred stoichiometry (1:1) of supported bimetallic PdZn nanoparticles is presented, involving the deposition of a heterobimetallic precursor, [PdZn(μ-OOCMe)4]2 on a CeZrOx support. After calcination and reduction, the material contained mainly a PdZn alloy, as revealed by powder XRD and XAFS, and further supported by XPS, TEM-EDX, elemental analysis and in-situ IR at low temperature using CO as probe molecule. Moreover, a minor phase of oxidized Zn was determined by XAFS. This PdZn/CeZrOx reduced catalyst was combined with SAPO-34 to form a tandem catalytic system for CO2 conversion to hydrocarbons. This system could readily convert CO2 and H2 at high temperature (380 °C) into hydrocarbons with a conversion of 24% and high relative selectivity in light hydrocarbons (C2-C3: 82%) with virtually no deactivation of the catalyst after 16 hours on stream. Controlled experiments were performed with Pd/CeZrOx and Zn/CeZrOx in order to gain supplementary insights on this system: Pd/CeZrOx gave only methane and Zn/CeZrOx gave mainly CO under the same conditions. The latter clearly shows that the control of the formation of PdZn phase has great impact for the selective production of hydrocarbons.

Abstract: International audience; Reduction of the specific consumption of aircraft would lead to substantial economic and environmental benefits. A promising technique consists in reducing skin friction drag by delaying the laminar-turbulent transition point as far aft as possible, particularly on the wings, in order to obtain lower friction coefficient in the presence of laminar flow. This can be achieved by Hybrid Laminar Flow Control (HLFC) technology. This paper presents the aerodynamic design of a largescale HLFC wing model for experiments that will be conducted in ONERA's S1MA wind-tunnel. The wing model is designed to investigate the major aerodynamic challenges that must be tackled to enable the development of HLFC airfoils: assessment in transonic flow conditions of the wing drag reduction due to HLFC suction, surface tolerance requirements on a HLFC wing and investigation of Attachment Line Contamination.

Abstract: International audience; Terrestrial laser scanners (TLS) are well known for providing an efficient means to monitor coastal cliff erosion. Cliffs along micro-tidal coasts, however, have often escaped quantification because the narrow or absent coastal platforms do not offer stable and embracing vantage points. To circumvent this issue, mobile laser scanning surveys from a boat can be used. We present a case study from Provence-Alpes-Côte-d'Azur (Mediterranean coast-southern France) to quantify cliff erosion in such micro-tidal environments. Three surveys were subcontracted over a period of 17 months to monitor a 3.5-km-long cliff of Carry-le-Rouet (15 km west of Marseille). Data quality was checked independently using man-made planar walls positioned above the cliff face, to retrieve survey precision and change detection thresholds. A boat-borne mobile LiDAR system was capable of describing planar features with a precision of 3–4 cm (epoch 1 and 2) and improved to 2.6 cm (epoch 3) with point densities around 100 points/m 2 . Absolute positioning accuracy varied between 0.1 cm and 0.3 cm. Because the coastline is very sinuous, we describe a method to unfold the point clouds using a continuous analytical surface made of vertical planes joined by arcs of cylinders and perform the analysis in 2.5D. Change was detected using a unique, conservative, threshold of 14 cm (99% quantile estimated on the plane change) on grids of 10 × 10 cm pixels. Integrated over the entire cliff face, the average annual cliff recession rate at Carry-le-Rouet is 1.1 cm/year. In 17 months, erosion was three times more effective in sandstone and marl layers than in calcarenites and conglomerates. Erosion varies vertically with erosion three times more effectively in the lower 25 m of the cliffs than above. Despite imperfections, boat-borne laser scanning systems are capable of delivering meaningful erosion data even in this low erosion context.

Abstract: The CO2 molecule is of great interest for astrophysical studies since it can be found in a large variety of astrophysical media where it interacts with the dominant neutral species, such as He, H2, or H2O. The CO2–He collisional system was intensively studied over the last two decades. However, collisional data appear to be very sensitive to the potential energy surface (PES) quality. Thus, we provide, in this study, a new PES of the CO2–He van der Waals complex calculated with the coupled-cluster method and a complete basis set extrapolation in order to provide rotational rate coefficients that are as accurate as possible. The PES accuracy was tested through the calculations of bound state transition frequencies and pressure broadening coefficients that were compared to experimental data. An excellent agreement was globally found. Then, revised collisional data were provided for the 10–300 K temperature range. Rate coefficients were compared to previously computed ones and are found to be up to 50% greater than previously provided ones. These differences can induce non-negligible consequences for the modeling of CO2 abundance in astrophysical media.

Abstract: International audience; Background and aims: One-third of hepatocellular carcinomas (HCCs) harbor mutations activating the β-catenin pathway predominantly via mutations in CTNNB1 gene itself. Mouse models of Apc loss-of-function are widely used to mimic β-catenin-dependent tumorigenesis. Given the low prevalence of APC mutations in human HCCs we aimed to generate liver tumors through CTNNB1 exon 3 deletion (βcatΔex3). We then compared βcatΔex3 liver tumors with liver tumors generated via frameshift in exon 15 of Apc (Apcfs-ex15).Methods: We used hepatocyte-specific and inducible mouse models generated through either a Cre-Lox or a CRISPR/Cas9 approach using AAV vectors. Tumors generated by the Cre-Lox models were phenotypically analyzed using immunohistochemistry and were selected for transcriptomic analysis by RNA-sequencing. Mouse RNAseq data were compared to human RNAseq data (8 normal tissues, 48 HCCs, 9 hepatoblastomas) in an integrative analysis. Tumors generated via CRISPR were analyzed using DNA sequencing and immunohistochemistry.Results: Mice with CTNNB1 exon 3 deletion in hepatocytes developed liver tumors indistinguishable from Apcfs-ex15 liver tumors. Both Apcfs-ex15 and βcatΔex3 mouse models induced growth of two phenotypically distinct tumors (differentiated or undifferentiated). Integrative analysis of human and mouse tumors showed that differentiated mouse tumors cluster with well-differentiated human CTNNB1-mutated tumors. Conversely, undifferentiated mouse tumors cluster with human mesenchymal hepatoblastomas and harbor activated YAP signaling.Conclusion: Apcfs-ex15 and βcatΔex3 mouse models both induce growth of tumors that are transcriptionally similar to either well-differentiated and β-catenin-activated human HCCs or mesenchymal hepatoblastomas.Lay summary: New and easy-to-use transgenic mouse models of liver primary cancers have been generated, with mutations in the gene coding beta-catenin, frequent in both adult and pediatric liver primary cancers. The mice develop both types of cancer, constituting a strong preclinical model.

Abstract: International audience; We carry out a theoretical investigation of the backward interaction optical parametric oscillator (OPO), in which one of the generated waves is counterpropagating with respect to the pump. We derive simple, self-consistent analytical formulas for the continuous-wave and pulsed regimes. While consistent with previous works on the continuous-wave regime, our study enables us to extend the analysis to the pulsed regime. In particular, we derive simple expressions of the oscillation build-up time, pulsed threshold, and efficiency, for the first time, to our knowledge. We also investigate the peculiar spectral features of the backward OPO when pumped with a narrow-linewidth pulsed radiation, in particular, the absence of tolerance to phase mismatch and the natural ability to emit two waves with a Fourier-transform-limited spectrum. A comparison with the conventional forward OPO is also carried out to emphasize the unique properties of the backward OPO.

Abstract: International audience; A highly efficient mirrorless OPO tunable in the mid-infrared around 2 µm has been developed and characterized in an original pumping configuration comprising a tunable high power hybrid Ytterbium laser MOPA (Master Oscillator Power Amplifier) in the nanosecond regime. The hybrid pump laser is based on a fiber laser seeder continuously tunable over several GHz at 1030 nm, which is shaped in the time domain with acousto-optic modulators (AOM), and power amplified in a dual stage Ytterbium doped fiber amplifiers, followed by two Yb:YAG bulk amplifiers. The pump delivers up to 3.5 mJ of energy within narrowband 15 ns pulses with a 5 kHz repetition rate. The output was focused into Periodically Poled KTP (PPKTP) crystals with a quasi-Phase Matching (QPM) period of 580 nm, producing Backward Optical Parametric Oscillation (BWOPO), with a forward signal wave at 1981 nm and a backward traveling idler at 2145 nm. We report significant optical to optical efficiencies exceeding 70 % depending on crystal length and input power. As theoretically expected, the forward wave could be continuously tuned over 10 GHz following the pump frequency sweep, while the backward wave remains almost stable, both being free from mode hops. These properties obtained from an optical arrangement without free-space cavities are attractive for future space Integrated Path Differential Absorption (IPDA) Lidar applications, which require robust and efficient tunable frequency converters in the mid-infrared.

Abstract: International audience; ObjectivesWhilst euthanasia and assisted suicide are forbidden by French Law, patients at the end of their life, hospitalized in Palliative Care Units (PCU) sometimes express such requests. The “DESA study” focused on the expression of patients’ requests for euthanasia and assisted suicide, i.e. how patients worded their wishes. The aim is to identify, from the “raw wording” of these requests, their common features, specificities and evolution.Patients/materials and methodsThis qualitative study took place in 11 French PCU during one year. It included adult patients who had made an explicit request for euthanasia or physician-assisted suicide to a health professional. According to the principles of grounded theory, semi-structured interviews were conducted within 48 hours of the initial request (D0), and then a week after this request (D7).ResultsEighteen Patients were initially interviewed. Only 9 were interviewed at D7. At D0, the initial request is a request for euthanasia. This request is expressing physical and psychological suffering, trauma and representations of death. At D7, we observe a semantic change: the request is less explicit and requires less intervention by a third party. It remains centred on death without suffering.ConclusionHealthcare providers need to actively listen to the request being made to be able to understand the meaning of the words and their function. It is their nuance, variety and evolution that help to better identify patients’ needs.

Abstract: Viscoelastic fluids are currently used for a wide variety of applications in food, chemical, cosmetics and pharmaceutical industries. They are dilute or semi-dilute solutions of high-molecular-weight polymers. For some concentrations, the controlled stretching of the fluid leads to the formation of beads-on-string structures which are characterized by drops connected by a filament. In our case, the controlled extension of the viscoelastic fluid is achieved thanks to an in-house filament stretching device. In order to analyse the 3D dynamic of the beads-on-string structure, i.e. to measure the displacement and the velocity of the bead-like drops during and after the stretching process, we use double exposure Holographic imaging. Holography allows us to choose a 3D volume of space to capture the entire phenomenon. Thanks to Holography, we can focus on one or several planes along the optical axis in order to estimate the 2D coordinates of beads in each plane. The computation of these planes leads to a reconstructed volume where the 3D displacements of beads along the x, y and z axes can be extracted. The dynamic of beads-on-string structures may depend on several factors which are linked to the fluid properties but also to the initial state and elongation parameters. The aim of this work is to experimentally identify the factors which are appropriate to observe a repeatable beads-on-string structure before studying the influence of an orthogonal air current.

Abstract: International audience; Aza-boron-dipyrromethenes (Aza-BODIPYs) are an increasingly studied class of fluorophores. They can be seen as an azadipyrromethene ("aza-DIPY") ligand rigidified by a metalloid, a boron atom. Based on this idea, a series of complexes of group 13 metals (aluminum and gallium) have been synthesized and characterized. The impact of the metal and of the nature of the substituents of aza-DIPY core were investigated. The photophysical and electrochemical properties were determined, and an X-ray structure of an azaGaDIPY was obtained. These data reveal that azaGaDIPY and azaAlDIPY exhibit significant red-shifted fluorescence compared to their analogue aza-BODIPY. Their emission can go up to 800 nm for the maximum emission length and up to NIR-II for the emission tail. This, associated with their electrochemical stability (no metal release whether oxidized or reduced) makes them a promising class of fluorophores for optical medical imaging. Moreover, X-ray structure and molecular modeling studies have shown that this redshift seems to be more due to the geometry around the boron/metal than to the nature of the metal.

Abstract: We study, both theoretically and numerically, qualitative and quantitative properties of the solutions a Vlasov-Poisson system modeling the interaction between a plasma and a cylindrical Langmuir probe. In particular, we exhibit a class of radial solutions for which the electrostatic potential is increasing concave with a strong variation in the vicinity of the probe which scales as the inverse of the Debye length. These solutions are proven to exist provided the incoming distributions of particles from the plasma verify the so called generalized Bohm condition of plasma physics. It extends the study [1]. Small perturbations of the radial semi-Maxwellian incoming distributions are then investigated numerically. We notably observe potential barriers that lead to the existence of unpopulated trapped orbits and to the presence of particles that by bypass the probe. Curves of the collected current versus its applied voltage are also presented. This work is the continuity of the previous work [2] where the existence of solutions has been proven.

33. 3D chemical structure of the diffuse turbulent ISM II - Origin of CH+, new solution to an 80 years mystery

Abstract: Aims: The large abundances of CH$^+$ in the diffuse interstellar medium (ISM) are a long standing issue of our understanding of the thermodynamical and chemical states of the gas. We investigate, here, the formation of CH+ in turbulent and multiphase environments, where the heating of the gas is almost solely driven by the photoelectric effect. Methods: The diffuse ISM is simulated using the magnetohydrodynamic (MHD) code RAMSES which self-consistently computes the dynamical and thermal evolution of the gas along with the time-dependent evolutions of the abundances of H$^+$, H, and H$_2$. The rest of the chemistry, including the abundance of CH$^+$, is computed in post-processing, at equilibrium, under the constraint of out-ofequilibrium of H$^+$, H, and H$_2$. The comparison with the observations is performed taking into account an often neglected, yet paramount, piece of information, namely the length of the intercepted diffuse matter along the observed lines of sight. Results: The quasi totality of the mass of CH$^+$ originates from the unstable gas, in environments where the kinetic temperature is larger than 600 K, the density ranges between 0.6 and 10 cm$^{-3}$, the electronic fraction ranges between 3 x 10$^{-4}$ and 6 x 10$^{-3}$, and the molecular fraction is smaller than 0.4. Its formation is driven by warm and out-of-equilibrium H$_2$ initially formed in the cold neutral medium (CNM) and injected in more diffuse environments and even the warm neutral medium (WNM) through a combination of advection and thermal instability. The simulation which displays the tightest agreement with the HI-to-H$_2$ transition and the thermal pressure distribution observed in the Solar Neighborhood is found to naturally reproduce the observed abundances of CH$^+$, the dispersion of observations, the probability of occurrence of most of the lines of sight, the fraction of non-detections of CH$^+$, and the distribution of its line profiles. The amount of CH$^+$ and the statistical properties of the simulated lines of sight are set by the fraction of unstable gas rich in H$_2$ which is controlled, on Galactic scales, by the mean density of the diffuse ISM (or, equivalently, its total mass), the amplitude of the mean UV radiation field, and the strength of the turbulent forcing. Conclusions: This work offers a new and natural solution to an 80 years old chemical riddle. The almost ubiquitous presence of CH$^+$ in the diffuse ISM likely results from the exchanges of matter between the CNM and the WNM induced by the combination of turbulent advection and thermal instability, without the need to invoke ambipolar diffusion or regions of intermittent turbulent dissipation. Through two phase turbulent mixing, CH$^+$ might thus be a tracer of the H$_2$ mass loss rate of CNM clouds., Astronomy and Astrophysics, EDP Sciences, In press

34. On the relationship between H2 addition, local extinction and hydrodynamic instability in non-premixed bluff-body stabilized flames

Abstract: We examined the effect of hydrogen (H2) enrichment to methane (CH4) in a non-premixed bluff-body stabilized burner operating under typical central jet dominated flame mode. In the chosen mode of operation, globally, the flow field and flame feature three important successive spatial regions, namely, recirculation zone, neck zone and jet-like flame zone. In such configuration, the flame is exposed to a higher stretch rate in the neck zone and eventually undergoes local extinction. Such local extinction and subsequent re-ignition of broken flame branches have strong implications over the hydrodynamic instability of the coaxial annular air shear layer. It is well known that H2 addition increases the flame extinction strain rate and thus alters the local extinction phenomenon. To understand this phenomenon, we performed experiments at 10%, 20 %, 30% and 50 % hydrogen proportion in (H2-CH4) blend. High repetition rate (5 KHz) PIV and OH PLIF measurements are performed simultaneously to perceive the quantitative insights. The results obtained from POD and 1D wavelet transform indicated the suppression of vortex shedding at the annular air shear layer for H2 addition greater than 20 %, and thus quantified the beneficial effect of H2 addition in turbulent flame stabilization.

Abstract: International audience; Investigating landscapes evolution and their responses to tectonic or climatic perturbation requires accurate representations and models of surfaces processes. Rivers are keys agents of the transmission of external forcing through landscape and the main drivers of continental denudation. For these reasons the mechanisms of fluvial incision have been a key focus of geomorphological research over the last decades.Long-term river incision is usually modeled with the Stream Power Model (Howard et al. 1997; Whipple & Tucker 1999) based on the along-stream evolution of drainage area and channel elevation gradient. More complex development of the SPM (Tucker 2004; Lague et al. 2005) combine instantaneous river incision with the probability for discharge occurrence and take into account incision threshold and discharge variability. These models have been confronted with fields data in a limited number of cases (DiBiase et al. 2011, Scherler et al. 2017, Campforts et al. 2020).Our objective is to investigate the behavior of stochastic-threshold incision models across the south-eastern margin of the Massif Central (France) where a strong gradient in discharge variability is reported. We present a new dataset combining measurements of discharge variability from gauging stations, denudation rates on 34 basins from 10Be cosmogenic nuclides and morphometric parameters from river long-profile analysis.Our results show a complex relationship between denudation rates and steepness index which cannot be explain only by the regional discharge variability gradient. When compared with measured erosion rates, we observe that the predictions of a stochastic-threshold incision model are not better than simpler versions of the SPM and require to take into account spatial variations in incision thresholds.

Abstract: Mid-latitude mountain glaciers sensitively respond to local summer temperature changes. Chronologies of past glacier fluctuations based on the investigation of glacial landforms therefore allows for a better understanding of warm-season climate variability at local scale. In this study, we focus on the Holocene, the current interglacial of the last 11,700 years, which remains matter of dispute regarding its temperature evolution and underlying driving mechanisms. In particular, the nature and significance of the transition from the early to mid-Holocene and of the Holocene Thermal Maximum (HTM) are still debated. Here, we apply a new approach by combining in situ cosmogenic 10Be moraine and 10Be-14C bedrock dating from the same site, the forefield of Steingletscher (European Alps), and reconstruct the glacier’s millennial recession and advance periods. The results suggest that subsequent to the final deglaciation at ~10 ka, the glacier was mostly smaller than its 2000 CE extent until ~3 ka, followed by the predominant occurrence of glacier advances until the end of the Little Ice Age in the 19th century. These findings agree with existing proxy records of Holocene summer temperature and glacier evolution in the Alps, showing that glaciers throughout the region retreated beyond modern extents for most of the Early and mid-Holocene. This implies that at least the summer climate of the HTM was warmer than that of the end of the 20th century for several millennia. Further investigations are necessary to refine the magnitude of warming and the potential HTM seasonality.

Subjects: [SCCO.PSYC]Cognitive science/Psychology, General Psychology
Abstract: International audience; Introduction. – Implicit theories of intelligence are beliefs that people form regarding the malleability of intelligence. The so-called“growth” and “fixed” mindsets respectively view intelligence as a characteristic that can or cannot be changed. Psychology, as ascience, also offers diverging responses. The developmental and differential traditions in the study of intelligence merely provide different answers because they do not focus on the same sources of variability nor on the same dimensions of intelligence.Objectives. – The research question that guided the present studies was: Are people’s naïve theories influenced by the same factors that drive developmental and differential psychologists to different conclusions?Method. – In Study 1, we first assessed participants’ (n = 509) reference norm orientation (i.e. whether they tend to focus on individual or social comparison), using a task in which they had to predict the school results of an hypothetical child. Then we administered a French version of Dweck’s (2007) mindset scale. In study2, we first asked participants (n = 530) to choose between two definitions of intelligence focusing either on its fluid or crystalized dimensions. Then we administered the French Mindset Scale andasked participants to justify their conclusion.Results. – Both variables of interest (reference norm orientation and preferred definition of intelligence) had a significant effect on the participant’s incremental beliefs.Conclusion. – The results of the two studies as well as the qualitative analysis of participants’ arguments suggest that mindsets, like scientific theories, partly stem from the fact that the same question regarding intelligence malleability can be approached with two different perspectives.; Introduction. – Les théories implicites de l’intelligence désignent des croyances concernant la modifiabilité de l’intelligence. Les états d’esprit « de développement » et « fixiste » considèrent respectivement l’intelligence comme une caractéristique qui peut ou ne peut pas être modifiée. La psychologie en tant que science offre, elle aussi, des réponses contrastées à cette question. Les approches développementales et différentielles fournissent des réponses divergentes parce qu’elles ne se concentrent pas sur les mêmes sources de variabilité ni sur les mêmes dimensions de l’intelligence.Objectifs. – La question de recherche était la suivante : les théories naïves des individus sont-elles influencées par les mêmes facteurs qui conduisent les psychologies développementale et différentielle à des conclusions différentes ?Méthode. – Dans l’étude 1, nous avons d’abord évalué l’orientation de la norme de référence des participants (n = 509) (centrée sur les progrès individuels ou la comparaison sociale), en utilisant une tâche de prédiction de note d’un enfant imaginaire. Ensuite,nous avons administré une version franc¸ aise de l’échelle de théorie implicite (Dweck, 2007). Dans l’étude 2, nous avons d’abord demandé aux participants (n = 530) de choisir entre deux définitions possibles de l’intelligence centrées sur ses dimensions fluide ou cristallisée, puis nous avons administré l’échelle de théorie implicite et demandé aux participants de justifier leur conclusion.Résultats. – Les deux variables investiguées ont un effet significatif sur les croyances incrémentielles exprimées par les participants.Conclusion. – Les résultats de même que l’analyse qualitative des arguments suggèrent que deux perspectives différentes orientent les théories naïves comme les théories scientifiques.

Abstract: International audience; We construct a stationary gyrokinetic variational model for sheaths close to the metallic wall of a magnetized plasma, following a physical extremalization principle for the natural energy. By considering a reduced set of parameters we show that our model has a unique minimal solution, and that the resulting electric potential has an infinite number of oscillations as it propagates towards the core of the plasma. We prove this result for the non linear problem and also provide a simpler analysis for a linearized problem, based on the construction of exact solutions. Some numerical illustrations show the well-posedness of the model after numerical discretization. They also exhibit the oscillating behavior.

Abstract: This article studies point-vortex models for the Euler and surface quasi-geostrophic equations. In the case of an inviscid fluid with planar motion, the point-vortex model gives account of dynamics where the vorticity profile is sharply concentrated around some points and approximated by Dirac masses. This article contains three main results with several links between each other. In the first part, we provide two uniform bounds on the trajectories for Euler and quasi-geostrophic vortices related to the non-neutral cluster hypothesis. In a second part we focus on the Euler point-vortex model and under the non-neutral cluster hypothesis we prove a convergence result. The third part is devoted to the generalization of a classical result by Marchioro and Pulvirenti concerning the improbability of collapses and the extension of this result to the quasi-geostrophic case.

Abstract: (IF 4.45: Q1); International audience; The emerged coral reef terrace sequence at Cape Laundi, on the north coast of Sumba Island (Indonesia), with at least 18 successive strandlines, remains poorly dated in spite of numerous previous data. The age discrepancies within these coral reef terraces (CRTs) were previously explained by their polycyclic nature, triggered by marine erosion and reoccupation of old coral colonies by new ones. This study aims at highlighting these processes, as well as the continental denudation that participates in the partial stripping of the thin superficial coral reef layer overlying the pre-existing surface, exhuming older coral colonies. For this purpose, we use a combined analysis of 36Cl cosmogenic concentrations, new 230Th/U ages, and previous dating in order to quantify denudation rates affecting the sequence and to highlight the role of marine erosion in reworking the lowest CRT surface. Our results demonstrate that 1) the lowermost CRT is composite, i.e., formed by different reefal limestone units constructed and eroded during successive highstands of the last interglacial, 2) following the last deglaciation, this CRT has been subjected again to coastal erosion and reoccupation during the Mid Holocene highstand, 3) its distal edge is affected by the current marine erosion and shows denudation rates higher by one to two orders of magnitude (from 279 ± 0.4 to 581 ± 0.4 mm ka−1) than the continental denudation values of higher CRTs (14.7 ± 8.3 mm ka−1 on average), 4) at the scale of a single CRT surface, variations in continental denudation rates are caused by epikarstification roughness, and 5) the distal edges have the highest continental denudation rate due to diffusion and regressive erosion produced by the runoff occurring along the steep downward cliff.
