This synthesis presents the most important disruptions of conceptions about the thymus since its discovery in Antique Greece. For centuries, the thymus has been considered as a vestigial organ, and its role in T-lymphocyte differentiation has been proposed only in the 1960’s. Most recent studies attribute to the thymus an essential and unique role in the programming of central immunological self-tolerance. The basal mechanism implicated in this function is the transcription in thymic epithelium of genes encoding precursors of self-antigens. Processing of these latters leads to presentation of self-antigens by the major histocompatibility complex (MHC) machinery expressed by thymic epithelial and dendritic cells. During fetal life, this presentation drives negative selection of T-cell clones harboring receptors with high affinity for these complexes MHC/self-antigen. After birth, this presentation promotes the generation of regulatory T cells specific for these complexes. A number of studies, as well as the identification of Aire and Fezf2 genes, have shown that a thymus dysfunction plays a crucial role in the development of organ-specific autoimmunity. [less ▲]

Well-defined poly(lactide)-based block copolymers were synthesized by a heterogeneous solvent and metal-free green approach by using organocatalysts in supercritical carbon dioxide (scCO2). We first report on the homopolymerization of both L- and D,L- lactide by organocatalyzed Ring-Opening Polymerization (o-ROP) by using a bicomponent organocatalyst composed of a thiourea derivative and various tertiary amines as cocatalysts. Control over the molar mass and dispersity is achieved until high monomer conversion although the polylactides are insoluble in the polymerization medium. The precision synthesis of PLA-based block copolymers from various CO2-phobic hydroxyl end-capped macroinitiators such as polyethylene glycol, polycaprolactone, polybutylene succinate and polyphosphoester was then reported. Merging scCO2 with this organocatalytic system provides therefore a unique tool for the design under solvent-free conditions of poly(lactide)-based block copolymers that are insoluble in scCO2.

Au fil des siècles, le corpus latin des vitae sanctorum et des passiones martyrum s’est enrichi par l’introduction de nouveaux textes, par la réécriture et l’adaptation d’anciens remis au goût du jour, ainsi que par la traduction d’oeuvres issues du monde byzantin. Le phénomène de la réécriture hagiographique est bien connu et a fait l’objet de nombreux travaux. Celui de la traduction dans ce domaine reste en revanche peu exploité, tant il existe d’obstacles à son étude (absence de répertoire, manque d’éditions critiques, difficultés à identifier les traductions et les modèles grecs, etc.). Le présent travail propose une approche originale du phénomène, basée sur l’utilisation de la statistique linguistique. Cette approche consiste à étudier le latin utilisé par les traducteurs hagiographes pour rendre leur modèle grec et les techniques qu’ils ont adoptées pour le traduire en considérant les traductions non pas une à une, mais d’une manière comparative au moyen de l’analyse quantitative, dans le but de caractériser et de classer les traductions sur base de critères linguistiques, d’identifier et de qualifier des pratiques, des traditions localisées, des spécificités d’école ou de traducteur. La pratique de la traduction est examinée à travers un corpus de 35 textes représentatif des différentes phases de l’histoire de la traduction hagiographique latine au Moyen Âge et des différents foyers de traduction en Italie. Les analyses sont menées sur divers paramètres lexicaux et syntaxiques, en comparant d’abord le corpus, pris dans son ensemble, à un corpus de textes non traduits, puis en comparant entre eux les différents sous-corpus de traductions. Le premier type de comparaison (externe) a pour objectif de mettre en évidence les caractéristiques des traductions en général, le second (interne) de dégager les spécificités de chaque groupe de traductions.

The phase behaviour of carbon dioxide/propargylic alcohols and carbon dioxide/oxetanes mixtures has been investigated using in-situ FTIR microspectrometry that allows us determining the evolution of the concentration of each component in the liquid phase as a function of temperature and pressure. It was at the same time possible to look inside the cell and to visualize the expansion of the liquid phase during the increase of the pressure. The measurements were performed at three different temperatures (40, 70 and 100◦C) for pressures ranging between 0.1 and 15 MPa. Propargylic alcohol (PA), 2-methyl-3-butyn-2-ol (MBOL), 3-butyn-1-ol (BOL) and trimethylene oxide (TMO) were selected as these molecules are used in the synthesis of cyclic or polycarbonates by coupling with CO2. Thus, we determined the CO2 sorption and the concentration of the substrate in the liquid phase. Thanks to these measurements, we established the pressure-composition phase diagram for the liquid phase of these substrate/CO2 binary mixtures. [less ▲]

The coupling of carbon dioxide (CO2) with epoxides with the formation of cyclic carbonates is a highly attractive 100% atom economy reaction. It represents a greener and safer alternative to the conventional synthesis of cyclic carbonates from diols and toxic phosgene. Today, cyclic carbonates find many applications as intermediates for fine chemicals synthesis, as electrolytes in Li-ion batteries, and polar aprotic solvents, but also serve for the synthesis of important polymers such as polycarbonates and polyurethanes. In view of their broad scope and their strong economic potential, there is a strong need to improve their synthesis and decrease their production costs. However, CO2 is a thermodynamically stable molecule, the use of catalysts is therefore mandatory for activating and facilitating the CO2/epoxide coupling reaction in a selective manner and under mild conditions. Recently organocatalysts deserved more and more interest in this field, and are viewed as alternatives to metal-based ones. Enormous progress has been made these last years to boost their performances, and some organocatalysts are now very competitive, cheap, readily available and exhibit good chemical stability towards moisture, water and air. This review is focusing on the recent advances in the development of metal-free organocatalysts for the synthesis of cyclic carbonates by CO2/epoxide coupling. Most of the state-of-the art organocatalysts used for this reaction are discussed, with a special emphasis to highlight the various routes employed to boost their performances. Their mode of action is also reported based on mechanistic considerations, supported by density functional theory (DFT) calculations that are becoming essential tools for modern catalysts design. Such detailed understanding of the mechanisms involving CO2 transformation should pave the way towards the definition of new modes of activation for converting CO2 with a large scope of substrates into various chemicals, monomers and polymers.

This paper proposes a novel control scheme for frequency support among asynchronous AC areas through HVDC grids. It is based on local controllers, each acting on a voltage source converter, using locally available measurements only, and supporting frequency of the adjacent AC area after a significant disturbance. The controller is combined with the existing DC voltage droop technique and is inspired of Model Predictive Control, taking into account various constraints. The coordination of the proposed control scheme with the existing secondary frequency control of an AC area is also discussed. Examples obtained from a test system with a five-terminal DC network connecting two asynchronous areas demonstrate the effectiveness of the proposed control scheme. [less ▲]

We propose a new method for automatic 3D multimodal registration based on anatomical landmark detection. Landmark detectors are learned independantly in the two imaging modalities using Extremely Randomized Trees and multi-resolution voxel windows. A least-squares fitting algorithm is then used for rigid registration based on the landmark positions as predicted by these detectors in the two imaging modalities. Experiments are carried out with this method on a dataset of pelvis CT and CBCT scans related to 45 patients. On this dataset, our fully automatic approach yields results very competitive with respect to a manually assisted state-of-the-art rigid registration algorithm. [less ▲]

Contrairement à la seconde reconstruction qui reste aujourd’hui largement inexplorée, la première reconstruction en Belgique a fait l’objet de nombreuses recherches et publications. Et pourtant, une figure essentielle n’a que très peu retenu l’attention des chercheurs : le chanoine Raymond A.G. Lemaire. Professeur d’archéologie et de restauration à l’université de Louvain, chantre du néogothique dans le sillage de Joris Helleputte, il participe activement aux débats de la reconstruction, non seulement à Louvain, où il est membre de la Commissie voor Stedenschoon, mais dans tout le pays, en tant que membre correspondant de la Commission royale des monuments et des sites et conseiller de l’archevêché de Malines. Auteur de nombreux articles, il synthétise les débats dans “La restauration des monuments anciens”, publiée à Anvers en 1938, tout en développant une approche personnelle se nourrissant de la théorie des valeurs d’Aloïs Riegl et s’approchant de la théorie du “cas par cas” développée à la même époque, en Italie, par Ambroggio Annoni. Bien que les rapports entre les deux hommes ne soient pas documentés dans les archives belges, les nombreux parallèles entre leurs approches, ainsi que le fait que le chanoine Lemaire enverra son neveu, Raymond M. Lemaire, se former chez Annoni en 1943, laissent entendre qu’ils devaient exister. A travers notre participation à la conférence, nous espérons découvrir des éléments susceptibles d’alimenter la poursuite des recherches en ce sens. [less ▲]

In Celsus' and Rogatianus' libraries – respectively at Ephesus and Timgad and the function of which is attested by inscriptions — bookcases are usually reconstructed in the niches. These examples have been used to identify other buildings which contained niches as libraries. However, Lora Johnson, in her 1984 Ph.D. thesis, rightfully questioned such an interpretation of the niches. The reconstruction of bookcases seems implausible, since the access to them would have been either impossible, or at least very difficult. The niches were more likely used for the display of statues. Similar arrangements can be found in various buildings, such as nymphaea or the scaenae frontes of theatres. Thus, the mere presence of niches inside a building does not allow to speculate about its function. This article aims at drawing attention to Lora Johnson’s work, the conclusions of which seem to be confirmed by new archaeological studies. [less ▲]
