We present the SVOM (Space-based multi-band astronomical Variable Objects Monitor) mission that the Chinese National Space Agency and the French Space Agency have decided to jointly implement. SVOM has been designed to detect all known types of gamma-ray bursts (GRBs), to provide fast and reliable GRB positions, to measure the broadband spectral shape and temporal properties of the GRB prompt emission, and to quickly identify the optical/near-infrared afterglows of detected GRBs, including high-redshift ones. Scheduled to be in orbit in the second half of the present decade, the SVOM satellite will carry a very innovative scientific payload combining for the first time a wide field X- and gamma-ray coded mask imager for GRB real-time localizations to few arcmin, a non-imaging gamma-ray monitor, and two narrow-field instruments for the study of the GRB early afterglow emission in the X-ray and visible bands. The SVOM payload is complemented by ground-based instruments including a wide-field camera to catch the GRB prompt emission in the visible band and two robotic telescopes to measure the photometric properties of the early afterglow. A particular attention is paid to the GRB follow-up in facilitating the observation of the SVOM detected GRB by the largest ground based telescopes., Comment: 13 pages, 3 figures.

Astrophysics - Abstract
According to recent analyses of the type-Ia supernova rate as a function of redshift, delayed and prompt type-Ia supernovae (SN Ia) should explode respectively in the Galactic bulge and in the nuclear bulge, a gas rich structure with ongoing star formation, located in the central region of the Milky Way. We estimate the rate of type-Ia supernovae in the Galactic bulge and nuclear bulge. We show that this rate is insufficient by an order of magnitude to explain by positron escape from type-Ia supernovae envelopes alone the large positron injection rate into the Galactic central region, as re-observed recently by the Spectrometer on INTEGRAL, which amounts to 1.25 10^{43} e+ s^{-1} and would require 0.5 SN Ia explosions per century., Comment: 5 pages, 3 figures.

Astrophysics - Abstract
Aims. We report the INTEGRAL/IBIS observations of the Coma Cluster in the hard X-ray/soft-ray domain. Methods. Since the Coma Cluster appears as an extended source, its global intensity and significance cannot be directly extracted with standard coded mask analysis. We used the method of imaging the extended sources with a coded mask telescope developed by Renaud et al. (2006). Results. The imaging capabilities and the sensitivity of the IBIS/ISGRI coded mask instrument allows us to identify for the first time the site of the emission above ~ 15 keV. We have studied the Coma Cluster morphology in the 18-30keV band and found that it follows the prediction based on X-ray observations.We also bring constraints on the non-thermal mechanism contribution at higher energies., Comment: 4 pages, 4 figures, Accepted for publication in A&A Letters

Astrophysics - Abstract
The Ibis/Isgri imager on Integral detected for the first time a hard X-ray source, IGR J17456-2901, located within 1' of Sgr A* over the energy range 20-100 keV. Here we present the results of a detailed analysis of ~7 Ms of Integral observations of the GC. With an effective exposure of 4.7 Ms we have obtained more stringent positional constraints on this HE source and constructed its spectrum in the range 20-400 keV. Furthermore, by combining the Isgri spectrum with the total X-ray spectrum corresponding to the same physical region around SgrA* from XMM data, and collected during part of the Integral observations, we constructed and present the first accurate wide band HE spectrum for the central arcmins of the Galaxy. Our complete analysis of the emission properties of IGR shows that it is faint but persistent with no variability above 3 sigma contrary to what was alluded to in our first paper. This result, in conjunction with the spectral characteristics of the X-ray emission from this region, suggests that the source is most likely not point-like but, rather, that it is a compact, yet diffuse, non-thermal emission region. The centroid of IGR is estimated to be R.A.=17h45m42.5, decl.=-28deg59'28'', offset by 1' from the radio position of Sgr A* and with a positional uncertainty of 1'. Its 20-400 keV luminosity at 8 kpc is L=5.4x10^35 erg/sec. Very recently, Hess detected of a source of ~TeV g-rays also located within 1' of Sgr A*. We present arguments in favor of an interpretation according to which the photons detected by Integral and Hess arise from the same compact region of diffuse emission near the central BH and that the supernova remnant Sgr A East could play an important role as a contributor of very HE g-rays to the overall spectrum from this region., Comment: 14 pages, 11 figures, Accepted for publication in ApJ

Astrophysics ,High Energy Physics - Phenomenology - Abstract
The bulk of the extragalactic background between 10 keV and 10 GeV is likely to be explained by the emission of Seyfert galaxies, type Ia supernovae, and blazars. However, as revealed by the INTEGRAL satellite, the bulge of our galaxy is an intense source of a 511 keV gamma-ray line, indicating the production of a large number of positrons that annihilate. The origin of the latter is debated, and they could be produced, in particular, by the (S- or P-wave) annihilation of light Dark Matter particles into e+e-. In any case, the cumulated effect of similar sources at all redshifts could lead to a new background of hard X-ray and soft gamma-ray photons. On the basis of the hierarchical model of galaxy formation, we compute analytically the SNIa contribution to the background, and add it to Seyfert and blazars emission models. We find that any extra contribution to this unresolved background at 511 keV should be lower than about 4 keV/cm^2/s/sr. We also estimate analytically the extragalactic background due to Dark Matter annihilation, increasing the accuracy of the earlier computations. Indeed, we take into account the large positron escape fraction from low mass dark matter halos, unable to confine a dense and magnetized interstellar medium. Our new background estimate turns out to be one order of magnitude lower, so that the hypothesis of a light Dark Matter candidate remains compatible with the observed extragalactic background for a wider range of particle masses and cross-sections., Comment: 10 pages, 8 figures, 1 table, accepted for publication in Physical Review D, improved with 4 new figures, 1 new table and 1 new part

7. Hypernovae as possible sources of Galactic positrons

Astrophysics - Abstract
INTEGRAL/SPI has recently observed a strong and extended emission resulting from electron-positron annihilation located in the Galactic center region, consistent with the Galactic bulge geometry, without any counterpart at high gamma-ray energies, nor in the 1809 keV $^{26}$Al decay line. In order to explain the rate of positron injection in the Galactic bulge, estimated to more than 10$^{43}$ s$^{-1}$, the most commonly considered positron injection sources are type Ia supernovae. However, SN Ia rate estimations show that those sources fall short to explain the observed positron production rate, raising a challenging question about the nature of the Galactic positron source. In this context, a possible source of Galactic positrons could be supernova events of a new type, as the recently observed SN2003dh/GRB030329, an exploding Wolf-Rayet star (type Ic supernova) associated with a hypernova/gamma-ray burst; the question about the rate of this kind of events remains open, but could be problematically low. In this paper, we explore the possibility of positron production and escape by such an event in the framework of an asymmetric model, in which a huge amount of $^{56}$Ni is ejected in a cone with a very high velocity; the ejected material becomes quickly transparent to positrons, which spread out in the interstellar medium., Comment: 8 pages, 2 figures.

Astrophysics - Abstract
It has been recently proposed that the observed 511 keV emission from the Galactic bulge could be the product of very light (1-100 MeV) annihilating dark matter particles. Other possible explanations for this signal are associated with stellar objects, such as hypernovae. In order to distinguish between annihilating light dark matter scenario and more conventional astrophysical sources for the bulge emission, we here propose the study of dwarf spheroidals such as Sagittarius. These galaxies have typical luminosities of $10^5 L_\odot$ but mass-to-light ratios of $\sim 100$. As there are comparatively few stars, the prospects for 511 keV emission from standard astrophysical scenarios are minimal. The dwarf spheroidals do, however, contain copious amounts of dark matter. INTEGRAL/SPI has observed the Sagittarius region. Analysis of this data for 511 keV emission will provide a test of MeV dark matter which can distinguish between annihilating dark matter and more standard astrophysics. The observation of such a signal from Sagittarius should be a ``smoking gun'' for MeV dark matter., Comment: 4 pages, no figures. Version accepted by Physical Review Letters

High Energy Physics - Phenomenology ,Astrophysics ,General Relativity and Quantum Cosmology ,High Energy Physics - Theory - Abstract
An intriguing feature of extra dimensions is the possible production of Kaluza--Klein gravitons by nucleon-nucleon bremsstrahlung in the course of core collapse of massive stars, as pointed out by Hannestad and Raffelt. In this event Kaluza--Klein gravitons are copiously produced and a significant fraction of them remains trapped around the newly born neutron stars. They slowly decay into 2 gamma rays, making neutron stars gamma-ray sources. In this letter, we strengthen considerably the limits on the radius of compactification of extra-dimensions for small number $n$ of them, or alternatively the fundamental scale of quantum gravity, considering the gamma-ray emission of the whole population of neutron stars sitting in the Galactic bulge, instead of the closest member of this category. For $n=1$ the constraint on the compactification radius is $R<400\mu$m, overlapping with the distance ($180\mu$m) at which Newtons law is directly measured. In addition, for n=1 and n=2, the fundamental energy scale of quantum gravity is far beyond the collider technology. These results imply that if $n\lesssim4$ and if strong gravity is around a TeV, the compactification topology is to be more complex than that of a torus., Comment: 4 pages, minor changes to text, matches published version

Astrophysics - Abstract
We briefly review the fundamentals of nuclear gamma-ray line astronomy (radioactive astronomy), focusing on its role to decipher the intimate physics of supernovae, either immediatly (via $^{56}Co)$ or after a time delay (via $^{44}Ti$). All kinds of supernovae can be in principle tested through their radioactivities and their associated gamma-ray lines. Dedicated to the spectroscopy and imaging of celestial sources in the 15 keV to 10 MeV band, the ESA scientific observatory INTEGRAL will open a golden age of nuclear astrophysics in Europe, Comment: Invited review, "Cosmic Evolution", meeting in honor of the 60th birthday of Jean Audouze and Jim Truran, to be published by World Scientific, 6 pages, 1 figure

Background Epigenome‐wide association studies for cardiometabolic risk factors have discovered multiple loci associated with incident cardiovascular disease (CVD). However, few studies have sought to directly optimize a predictor of CVD risk. Furthermore, it is challenging to train multivariate models across multiple studies in the presence of study‐ or batch effects. Methods and Results Here, we analyzed existing DNA methylation data collected using the Illumina HumanMethylation450 microarray to create a predictor of CVD risk across 3 cohorts: Women's Health Initiative, Framingham Heart Study Offspring Cohort, and Lothian Birth Cohorts. We trained Cox proportional hazards‐based elastic net regressions for incident CVD separately in each cohort and used a recently introduced cross‐study learning approach to integrate these individual scores into an ensemble predictor. The methylation‐based risk score was associated with CVD time‐to‐event in a held‐out fraction of the Framingham data set (hazard ratio per SD=1.28, 95% CI, 1.10–1.50) and predicted myocardial infarction status in the independent REGICOR (Girona Heart Registry) data set (odds ratio per SD=2.14, 95% CI, 1.58–2.89). These associations remained after adjustment for traditional cardiovascular risk factors and were similar to those from elastic net models trained on a directly merged data set. Additionally, we investigated interactions between the methylation‐based risk score and both genetic and biochemical CVD risk, showing preliminary evidence of an enhanced performance in those with less traditional risk factor elevation. Conclusions This investigation provides proof‐of‐concept for a genome‐wide, CVD‐specific epigenomic risk score and suggests that DNA methylation data may enable the discovery of high‐risk individuals who would be missed by alternative risk metrics.

- Abstract
Cet ouvrage traite de l’une des décisions les plus importantes dans la vie d’une entreprise ayant atteint une taille respectable : son introduction en bourse. Il s’agit d’un thème particulièrement intéressant et clivant dans la mesure où il conditionne le développement de la société concernée, mais où il donne lieu à des controverses acharnées. En effet, il arrive un moment où ses capitaux s’avérent insuffisants pour lui permettre d’assurer sa croissance. Il lui faut donc trouver des fonds supplémentaires. Elle dispose pour ce faire de plusieurs moyens, dont réaliser un prêt à très long terme, une augmentation de capital soit auprès de ses actionnaires historiques soit auprès de nouveaux actionnaires. C’est à cette question que cet ouvrage est consacré, en expliquant les avantages, les inconvénients et les risques de chacune des modalités envisageables.Écrit par deux spécialistes du financement d’entreprises, à la fois patriciens et théoriciens, ce sujet fait l’objet de changements constants au gré de l’évolution des pratiques financières. S’appuyant sur les dernières statistiques connues, il permet de comprendre l’enjeu pour une jeune entreprise ou pour une entreprise mature d’une cotation en bourse ou, même, parfois, pour l’ensemble de la population d’un pays.

Introduction: Dietary modification that reflects healthy eating is a notable strategy for CVD prevention on a population level. The cardioprotective role diet plays in hemostasis and thrombosis, particularly in respect to platelet function remains unclear. Hypothesis: Healthier Alternative Healthy Eating Index (AHEI) scores associate with attenuated platelet reactivity in a large-scale population cohort. Methods: Cross-sectional data was obtained from Framingham Heart Study participants (N=3,429). AHEI scores were derived from self-reported Harvard semi-quantitative food frequency questionnaires. Ranging from 0 to 110, higher AHEI scores reflect healthier overall diet quality. Five bioassays measured platelet reactivity traits across several agonists in whole blood and platelet-rich plasma samples. Linear mixed effects models adjusted for age, sex, aspirin use, family relatedness, daily energy intake, and BMI evaluated associations between platelet reactivity and AHEI scores and components. Results: Higher AHEI scores associated with attenuated platelet reactivity among 16 different traits (P Conclusions: We report that higher AHEI scores associate with decreased platelet reactivity. Effects appear strongest for EPA & DHA intake consistent with several small randomized controlled trials. However, we found that a holistic AHEI score reflects a better interpretation of diet as a modulator of platelet function compared to individual components. Our results conclude that the impact of a healthier diet in preventing thrombosis may be partially mediated through a decline in platelet reactivity through multiple independent activation pathways.

Cognitive decline, anxiety, and depression are significant contributors to human ill health and decreased quality of life. Intake of fruits including 100% juice is associated with beneficial effects on several health outcomes. The current study explored the potential associations between consumption of 100% fruit juice and neurocognitive markers in adults. Twenty-four-hour dietary recall data from the National Health and Nutrition Examination Survey (NHANES) 1988–1994, 1999–2018 for adults 20+ years (N = 62,606) were used to assess 100% fruit juice intake, and NHANES questionnaire data were used for the assessment of neurocognition. Association of usual intake of 100% fruit juice with neurocognitive outcomes were assessed by regression analysis after adjusting for demographic, lifestyle, dietary, and health-related covariates. About 21% of adults were fruit juice consumers and the intake was a little over 2 oz per day. Consumers of 100% fruit juice had 16.3% fewer days per month of feeling anxious compared to non-consumers. There were no significant associations of 100% fruit juice usual intake with other neurocognitive measures. A large number of potential confounding variables have been identified to be associated with one or more neurocognitive measures suggesting that these may be important parameters to include in future studies.

Soil fertility, growth, nutrient uptake and yield traits of peanut (Arachis hypogaea L. var. JL24) were investigated under two organic fertilizers (indigenous microorganisms (IMO) or effective microorganisms (EM) with three replications. Application of IMO or EM fertilizers had significant effects on soils fertility compared to untreated soils. Total nitrogen, organic carbon, total phosphorus, calcium and magnesium led to a significant increase under organic fertilizers. IMO fertilizer supply at 20 g significantly increased the shoot length and the number of leaves compared to the EM fertilizer and untreated plants. In contrast, the highest values of stem diameter and leaf area were recorded at 40 g of EM supply. The highest values of pod (1.25 and 1.18 t/ha) and grain yield (0.96 and 0.98 t/ha) were recorded at 10 and 20 g for IMO and EM, respectively. Application of EM and IMO at 10 or 20 g led to a significant increase in nitrogen and phosphorus contents in leaves and roots with the highest accumulation of nitrogen at the roots level of treated plants. Nitrogen and proteins contents of peanut seeds were positively influenced by IMO and EM supply at 10 and 20 g, respectively. The use of IMO and EM fertilizers could enhance peanut growth performance in sandy ferralitic soils. Key words: Field performance, plant growth, fertilizers, yield traits, Arachis hypogaea.

The aim of this study was to propose a methodology for the assessment of non-inferiority with meta-analysis. Assessment of hypofractionated RT in prostate and breast cancers is used as an illustrative example. Non-inferiority assessment of an experimental treatment versus an active comparator should rely on two elements: (1) an estimation of experimental treatment’s effect versus the active comparator based on a meta-analysis of randomized controlled trials and (2) the value of an objective non-inferiority margin. This margin can be defined using the reported effect of active comparator and the percentage of the active comparator’s effect that is desired to be preserved. Non-inferiority can then be assessed by comparing the upper bound of the 95% confidence interval of experimental treatment’s effect to the value of the objective non-inferiority margin. Application to hypofractionated RT in breast cancer showed that hypofractionated whole breast irradiation (HWBI) appeared to be non-inferior to conventionally fractionated RT for local recurrence. This was not the case for accelerated partial breast irradiation (APBI). Concerning overall survival, non-inferiority could not be claimed for either HWBI or APBI. For prostate cancer, the lack of demonstrated significant superiority of conventional RT versus no RT precluded any conclusion regarding non-inferiority of hypofractionated RT.

27. Foi et doctrines chez les croyants des hérétiques

Paul, Jacques
- Abstract
The hope of salvation, a dominant preoccupation of the Cathar believers, seems to leave little place for heretical theses. Many of the depositions made before the Inquisition show them ignorant of the most fundamental doctrines. One must take care in drawing radical conclusions, because it only takes one simple believer to have a serious knowledge of heresy to invalidate this opinion. In the middle of the XIIIth century, the dossier compiled against Pierre Garcias du Bourget Nau is a brilliant proof of this. He often deploys a subtle argument to give the texts from Scripture a meaning consistent with his convictions. All these propositions find precise echoes in the Traité cathare anonyme, in the Summa quadripartite of Alain de Lille, and equally in the treatise of Moneta of Cremona. A simple believer, he is probably of oral culture, and his knowledge comes from long frequenting of heretical circles. He gives the name of those he holds responsible for his education, which leads one to believe that, as a believer who has a good knowledge of heresy, he is not alone., L’espérance du salut, préoccupation dominante des croyants cathares semble laisser peu de place aux thèses hérétiques. Bien des dépositions devant l’Inquisition les montrent ignorants des doctrines les plus fondamentales. Il faut se garder d’en tirer des conclusions radicales car il suffit qu’un simple croyant ait une connaissance sérieuse de l’hérésie pour infirmer cette opinion. Au milieu du XIIIe siècle le dossier réuni contre Pierre Garcias du Bourget Nau en apporte la preuve éclatante. Il use d’une argumentation souvent subtile pour donner aux textes de l’Écriture un sens conforme à ses convictions. Tous ses propos trouvent des échos précis dans le Traité cathare anonyme, dans la Summa quadripartita d’Alain de Lille et également dans le traité de Moneta de Crémone. Simple croyant, il est vraisemblablement de culture orale et son savoir vient d’une longue fréquentation des cercles hérétiques. Il donne le nom de ceux dont il tient sa formation ce qui laisse entendre qu’un croyant qui a une bonne connaissance de l’hérésie n’est pas seul., Paul Jacques.

Background: Identifying circulating proteins associated with healthy dietary patterns may offer novel insights into the key biological processes underlying diet-related chronic disease. As a first step toward achieving this goal, we examined the relations between a proteomic score of healthy dietary patterns and the risk of cardiovascular disease (CVD). Methods: We evaluated up to 1713 Framingham Offspring Study participants (1991-1995, mean age 54yr, 55% women) who had plasma proteins assayed using the SomaLogic platform and diet assessed using a validated food frequency questionnaire. We regressed three healthy dietary pattern indices (Alternative Healthy Eating Index, Dietary Approaches to Stop Hypertension [DASH], and Mediterranean-style diet) on 103 diet-related proteins using elastic net regression (separate model for each diet index) with a 10-fold cross-validation (CV). Protein selection was based on the minimum mean CV error. A proteomic score was created by summing (concentration*β coefficient) of selected proteins, and validated in 862 Framingham Third Generation Cohort participants (2008-2011, mean age 46yr, 56% women). We used multivariable Cox proportional hazard models to relate the proteomic score and dietary pattern indices (separate models) to CVD in participants free of CVD (n=2459). All models adjusted for age, sex, smoking, and lipid medication use. Additional models adjusted for 1) both the proteomic score and dietary pattern indices and 2) body mass index, total cholesterol to high-density lipoprotein cholesterol ratio, triglycerides, diabetes mellitus, and hypertension. Results: Across three dietary patterns, 11 proteins characterized the proteomic score. Partial correlations of the proteomic score with the healthy dietary patterns ranged from r=0.33-0.36 (adjusted for age, sex, and total energy) in the validation sample, with the strongest correlation for the DASH index. Over a mean follow-up of 20 years, 510 participants developed CVD. Adjusting for age, sex, smoking, and lipid medication, a 1-SD unit increase in the proteomic score was associated with a 22% lower risk of CVD (hazard ratio [95% CI] 0.78 [0.72, 0.84]) and a 1-SD unit increase in the DASH index was associated with a 15% lower risk of CVD (hazard ratio 0.85 [0.77, 0.93). In mutually-adjusted models, relations of the proteomic score with CVD (0.80 [0.73, 0.87]), and of the DASH index with CVD were maintained (0.89 [0.82, 0.97]). Upon further adjustment for metabolic risk factors, relations of the proteomic score and CVD were attenuated (0.96 [0.87, 1.05]), but relations of the DASH index with CVD were unchanged (0.89 [0.80, 0.98]). Conclusion: We characterized a distinct proteomic score of healthy dietary patterns in a community-based cohort of adults. A healthy diet proteomic score may represent variation in the proteome that influences CVD risk.

Based on the Cloude/van Zyl decomposition of reflection symmetric polarimetric SAR data we present a version for full/quad polarisation data. We demonstrate both versions on X-band F-SAR data over Vejers, Denmark. Differences between the original and our version of the decomposition occur especially for very bright man-made targets. These differences come with lower entropy for our version giving an improved focus on a more pronounced dominant scattering mechanism for these objects. Interpretation of the scattering mechanism related to the full/quad pol version of the decomposition is facilitated by means of the Cloude/Pottier ¯α angle.

Genetics ,QH426-470 - Abstract
Circulating homocysteine levels (tHcy), a product of the folate one carbon metabolism pathway (FOCM) through the demethylation of methionine, are heritable and are associated with an increased risk of common diseases such as stroke, cardiovascular disease (CVD), cancer and dementia. The FOCM is the sole source of de novo methyl group synthesis, impacting many biological and epigenetic pathways. However, the genetic determinants of elevated tHcy (hyperhomocysteinemia), dysregulation of methionine metabolism and the underlying biological processes remain unclear. We conducted independent genome-wide association studies and a meta-analysis of methionine metabolism, characterized by post-methionine load test tHcy, in 2,710 participants from the Framingham Heart Study (FHS) and 2,100 participants from the Vitamin Intervention for Stroke Prevention (VISP) clinical trial, and then examined the association of the identified loci with incident stroke in FHS. Five genes in the FOCM pathway (GNMT [p = 1.60 × 10(-63)], CBS [p = 3.15 × 10(-26)], CPS1 [p = 9.10 × 10(-13)], ALDH1L1 [p = 7.3 × 10(-13)] and PSPH [p = 1.17 × 10(-16)]) were strongly associated with the difference between pre- and post-methionine load test tHcy levels (ΔPOST). Of these, one variant in the ALDH1L1 locus, rs2364368, was associated with incident ischemic stroke. Promoter analyses reveal genetic and epigenetic differences that may explain a direct effect on GNMT transcription and a downstream affect on methionine metabolism. Additionally, a genetic-score consisting of the five significant loci explains 13% of the variance of ΔPOST in FHS and 6% of the variance in VISP. Association between variants in FOCM genes with ΔPOST suggest novel mechanisms that lead to differences in methionine metabolism, and possibly the epigenome, impacting disease risk. These data emphasize the importance of a concerted effort to understand regulators of one carbon metabolism as potential therapeutic targets.

- Abstract
The research in this thesis shows that enol carbamates react with hyper-reactive cysteine and serine residues within proteins. By equipping the scaffold with a reporter group, chemical probes can be obtained that label enzyme containing these residues. The reactivity of the scaffold can be tuned to increase the potency and to generate selectivity for proteins of interest.

Religion ,Moyen Âge ,History ,christianisme - Abstract
À l’occasion du départ à la retraite de Michelle Fournie, ses collègues historiens et historiens de l’Art de l’Université de Toulouse II le Mirail ont souhaité réunir en son honneur un volume de Mélanges. Bien plus qu’un volume disparate, nous avons voulu construire un ouvrage cohérent organisé autour de ses thèmes de recherche. Le dialogue établi entre le Ciel et la Terre à la fin du Moyen Âge fut notre guide. En effet, l’œuvre majeure de Michelle Fournie, Le ciel peut-il attendre ? Le culte du Purgatoire dans le Midi de la France, publié aux Éditions du Cerf en 1997 a marqué nombre d’historiens de la religion et des mentalités. Les premiers temps de cette conversation sacrée prennent ici la forme d’une interrogation sur les modalités des suppliques adressées aux reliques des saints et à leurs images en Europe à la fin du Moyen Âge. Le colloque pacifique ou tendu entre le Ciel et la Terre se poursuit au travers d’une série de contributions consacrées aux Églises méridionales et à leurs rapports aux pouvoirs terrestres. Enfin, la relation se conclut en donnant la parole aux dévotions collectives et aux différentes formes de la piété ordinaire. Ce volume constitue, certes, un hommage, mais il est aussi, nous l’espérons, une pérégrination sur les chantiers actuels de l’histoire religieuse et des mentalités médiévales.

Enseigner la foi aux chrétiens est de la compétence de l’évêque. À ce titre il doit prêcher, en personne si possible ou déléguer éventuellement son pouvoir. Il lui incombe de faire revenir de leurs erreurs ceux qui se seraient égarés loin de la bonne doctrine. Il doit les convaincre. Leur rétractation peut s’accompagner d’une pénitence, car il est juge de la foi. S’il estime l’hérétique endurci, il peut faire appel aux pouvoirs civils.

We describe the use of P-band data from DLR’s F-SAR system to change detection between three time points. Change detection on data in the covariance matrix representation is performed by means of test statistics in the complex Wishart distribution on both multi- and single-look data. We successfully detect objects including humans buried under snow in Disko Island, Greenland.

- Abstract
Fully polarimetric SAR gives valuable information on the nature of scattering mechanisms, which can be used for vehicle detection. This project aims at comparing the contrast between vehicles and background offered by different polarimetric features, at different wavelengths and under different orientation angles. The study is based on data acquired with DLR’s FSAR, in Oksbøl, Denmark, at X, S and L bands. This work can lead to further improvements in target detection by selecting individual features or a combination of features optimizing contrast between vehicles and their surroundings.

Background: It is unclear whether high-dose regimens of tranexamic acid in cardiac surgery (total dose, 80 to 100 mg/kg) confer a clinical advantage over low-dose regimens (total dose, approximately 20 mg/kg), particularly as tranexamic acid-associated seizure may be dose-related. The authors' aim was to characterize the exposure-response relationship of this drug.Methods: Databases were searched for randomized controlled trials of intravenous tranexamic acid in adult patients undergoing cardiopulmonary bypass surgery. Observational studies were added for seizure assessment. Tranexamic acid concentrations were predicted in each arm of each study using a population pharmacokinetic model. The exposure-response relationship was evaluated by performing a model-based meta-analysis using nonlinear mixed-effect models.Results: Sixty-four randomized controlled trials and 18 observational studies (49,817 patients) were included. Seventy-three different regimens of tranexamic acid were identified, with the total dose administered ranging from 5.5 mg/kg to 20 g. The maximum effect of tranexamic acid for postoperative blood loss reduction was 40% (95% credible interval, 34 to 47%), and the EC50 was 5.6 mg/l (95% credible interval, 0.7 to 11 mg/l). Exposure values with low-dose regimens approached the 80% effective concentration, whereas with high-dose regimens, they exceeded the 90% effective concentration. The predicted cumulative blood loss up to 48 h postsurgery differed by 58 ml between the two regimens, and the absolute difference in erythrocyte transfusion rate was 2%. Compared to no tranexamic acid, low-dose and high-dose regimens increased the risk of seizure by 1.2-fold and 2-fold, respectively. However, the absolute risk increase was only clinically meaningful in the context of prolonged open-chamber surgery.Conclusions: In cardiopulmonary bypass surgery, low-dose tranexamic acid seems to be an appropriate regimen for reducing bleeding outcomes. This meta-analysis has to be interpreted with caution because the results are observational and dependent on the lack of bias of the predicted tranexamic acid exposures and the quality of the included studies.Editor’s Perspective: [ABSTRACT FROM AUTHOR]- Published

Les onze articles de Jacques Paul rassemblés dans ce volume, dont l'édition est offerte à l'auteur par le Centre de Recherche SICMA (Sociétés, Idéologies, Croyances au Moyen Âge) de l'Université de Provence, témoignent d'un univers intellectuel dans lequel le lecteur est invité à s'engager, comme le voyageur sur une route nouvelle. Chacun d'eux constitue une approche phénoménologique d'une partie du vécu des hommes du Moyen Âge et de leur perception du monde, fondée sur la critique d'œuvres littéraires ou artistiques. Miracles et mentalité religieuse, dévotion populaire, symbolique d'une tapisserie de la Création, d'un manteau impérial, d'une représentation de la Rome éternelle, interrogations sur les « schémas imaginatifs », les « attitudes mentales », sur le caractère polyvalent des gestes et des paroles, autant de domaines parfaitement maîtrisés par l'auteur, et l'occasion pour le lecteur de faire, dans la relecture de ces articles dont certains ont été réécrits, de nouvelles découvertes.
