In post-genocide Rwanda, in addition to gacaca courts, a truth commission is needed in order to promote justice and foster reconciliation. In the context of transitional justice, retributive justice, which seeks justice and focuses on the perpetrators, appears to be inadequate to lead a society towards reconciliation. Therefore, some forms of restorative justice, which emphasize the healing of the whole society, seem necessary. In Rwanda, gacaca courts and a truth commission are complementary. The former can bring justice, the latter can seek the truth; both crucial ingredients of a peaceful future for Rwandans. The essay opens with the discussion of the nature of the genocide and the responses to post-genocide Rwanda’s crisis. The second and third parts present the existent gacaca system and a theoretical framework for a truth commission. The combination of both approaches in view of the double goal of justice and reconciliation conclude this paper. [less ▲]

Many substances released in the aquatic environment have been reported to have disruptive effects on endocrine systems of vertebrates and invertebrates. In rotifers, some of these chemicals have been shown to depress sexual reproduction at concentrations one to two orders of magnitude below those that affect asexual reproduction. The anti-androgen flutamide impacts sexual reproduction of rotifers at particularly low concentrations. We studied the effect of different types of putative endocrine disruptors on sexual reproduction of Brachionus calyciflorus. Contaminants tested were cyproterone acetate, an anti-androgen with a steroid-like structure, the pesticides fenitrothion and linuron which both have high affinity to the androgen receptor in vertebrates, although they are nonsteroidal molecules, and lindane a widely used pesticide that binds weakly to the androgen receptor in vertebrates. A series of endpoints relative to different steps of sexual reproduction were monitored to define critical functions affected and to get information on mechanisms of action. Fenitrothion, had the strongest impact on the sexual reproduction of rotifers. We observed a decrease in the proportion of mictic females among the ovigerous individuals and in the production of fertilized eggs per female that was proportional to the dose. The most sensitive parameter was the number of males produced per mictic female which was considerably higher in treated animals even at concentrations 10 times lower than the NOEC of asexual reproduction.

Checking infinite-state systems is frequently done by encoding infinite sets of states as regular languages. Computing such a regular representation of, say, the reachable set of states of a system requires acceleration techniques that can finitely compute the effect of an unbounded number of transitions. Among the acceleration techniques that have been proposed, one finds both specific and generic techniques. Specific techniques exploit the particular type of system being analyzed, e.g. a system manipulating queues or integers, whereas generic techniques only assume that the transition relation is represented by a finite-state transducer, which has to be iterated. In this paper, we survey two generic techniques that have been presented in [B. Boigelot and A. Legay and P. Wolper, Iterating Transducers in the Large, Proc. 15th Int. Conf. on Computer Aided Verification, Boulder, USA, Lecture Notes in Computer Science, volume 2725, year 2003, pages 223–235] and [B. Boigelot and A. Legay and P. Wolper, Omega-Regular Model Checking, Proc. 10th Int. Conf. on Tools and and Algorithms for the Construction and Analysis of Systems, Barcelona, Spain, Lecture Notes in Computer Science, volume 2988, year 2004, pages 561–575]. Those techniques build on earlier work, but exploits a number of new conceptual and algorithmic ideas, often induced with the help of experiments, that give it a broad scope, as well as good performance.

Les réponses comportementales du bar, Dicentrarchus labrax, ont été examinées après exposition aux ions cadmium en conditions contrôlées de laboratoire. Le but de cette étude était de découvrir si les ions cadmium étaient capables d’inactiver les neuromastes du système latéral du poisson et de déterminer les conséquences comportementales d’un tel blocage sensoriel chez des poissons soumis à des dangers artificiels. Pour cela, le comportement de fuite des poissons en réponse à un jet d’eau artificiel a été enregistré grâce à une caméra vidéo analogique (25 images.s-1) avant et après l’exposition au cadmium. Le protocole expérimental a été testé sur des poissons dont le système latéral avait été artificiellement endommagé par des antibiotiques (gentamicine et streptomycine). Les contrôles histologiques réalisés en microscopie électronique à balayage ont montré que le traitement antibiotique avait détruit les neuromastes du système latéral. En parallèle, ces poissons ne répondaient plus aux stimulations engendrées par le jet d’eau après un tel traitement. Le comportement de fuite des poissons a ensuite été enregistré avant puis après une exposition au cadmium à deux concentrations différentes. Lorsque les bars ont été exposés à la première concentration testée (0.5 µg.l-1, ce qui représente la concentration maximale rencontrée dans des estuaires contaminés), aucune altération des tissus des neuromastes n’a été observée. De plus, avant l’exposition au cadmium, les poissons répondaient de manière positive à 98.41 ± 4.95 % (n = 42) des stimulations de leur système latéral (réponse de fuite face au jet d’eau). Après l’exposition au cadmium, aucune modification comportementale n’a été détectée : les poissons répondaient positivement à 95.16 ± 9.79 % (n = 41) des stimulations ( ² = 2.464, p = 0.116). Au contraire, la concentration la plus élevée de cadmium testée (5 µg.l-1, ce qui représente 10 fois la concentration rencontrée dans les estuaires fortement pollués) a entraîné de sévères dommages au niveau des tissus des neuromastes. Juste après une telle exposition au cadmium, les poissons présentaient seulement 41.67 ± 35.36 % (n = 2) de réponses positives aux stimulations de leur système latéral, alors qu’ils répondaient positivement à 95.93 ± 9.10 % (n = 41) des stimulations en conditions témoins ( ² = 24.562, p < 0.0001). Les neuromastes de leur système latéral ont semblé se régénérer au bout d’environ un mois après l’exposition au cadmium. Associée à cette régénération, à partir du 21ème jour suivant l’exposition au cadmium, leur comportement de fuite s’est restauré et n’était plus significativement différent de celui enregistré en conditions témoins (86.74 ± 20.82 %, n = 11, ² = 2.876, p = 0.090). Cette étude montre que si la concentration de cadmium de 5 µg.l-1 est capable d’endommager les neuromastes du système latéral et de provoquer des altérations comportementales chez les poissons, les bars exposés à 0.5 µg.l-1 de cadmium ne présentent ni dommage tissualaire de leurs neuromastes, ni modification comportementale.

Les Pomacentridae (Damselfishes), comme la plupart des poissons des récifs coralliens, possèdent un cycle de vie complexe comprenant une phase larvaire pélagique dispersive, et une phase juvénile et adulte benthique associée au milieu corallien. Le passage du stade larvaire au stade juvénile se fait au cours d’un véritable processus de métamorphose qui généralement coïncide avec la colonisation du récif. Cette transition est une phase cruciale impliquant un changement du mode de vie qui peut s’accompagner de modifications morphologiques. A l’heure actuelle, peu d’information existe sur ce qui caractérise la métamorphose des poissons récifaux d’un point de vue squelettique et leurs implications fonctionnelles. Celle-ci n’est principalement décrite que par des changements de pigmentation et des changements morphologiques telles que des modifications de proportions du corps. L’objectif de cette étude est de caractériser les changements de forme des structures céphaliques directement impliquées dans la prise de nourriture chez deux espèces de Pomacentridae : Pomacentrus pavo (Bloch, 1787) et Dascyllus aruanus (Linnaeus, 1758). Dans cette étude, la morphométrie géométrique basée sur la méthode des points repères est utilisée pour décrire les trajectoires de croissance et les changements de forme caractérisant les pièces squelettiques durant la période de colonisation du récif. Cette analyse est appliquée aux quatre unités fonctionnelles suivantes : le neurocrâne, l’ensemble « suspensorium et opercule », la mandibule et le prémaxillaire. Celles-ci sont étudiées en vue latérale. Les patrons de transformations de chaque structure durant le développement sont décrits morphologiquement au moyen de grilles de déformation. Les modifications morphologiques observées chez P. pavo et D. aruanus durant le développement vont dans le sens d’une amélioration du système de prise de nourriture par aspiration. Les principaux changements sont : un agrandissement en hauteur et en largeur du suspensorium et de l’opercule, une élévation de la crête supraoccipitale, un déplacement vers l’avant de l’articulation mandibulaire, un raccourcissement de la mandibule et un allongement du processus ascendant du prémaxillaire. Ces transformations au niveau de la tête pourraient refléter un changement de mode de prise de nourriture au cours de l’ontogénie. La comparaison des unités fonctionnelles entre les deux espèces à l’état larvaire révèle que certaines unités (mandibule par exemple) sont très similaires dans leur forme tandis que d’autres (neurocrâne, unité « suspensorium et opercule » et le prémaxillaire) présentent une forme déjà dissemblable. Cependant, la similarité observée laisse clairement supposer que ces pièces sont sujettes aux mêmes contraintes de prise de nourriture : leurs formes permettraient de les considérer comme des « ram-feeders » se nourrissant du même type de proie. Au cours de leur croissance et de la colonisation du récif, la différenciation des entités squelettiques entre chaque espèce se renforce, permettant ainsi à chacune de s’installer progressivement dans sa niche écologique. Les différences entre les larves et les adultes paraissent liées au moins aux contraintes écologiques. [less ▲]

A strongly gravity-darkened model atmosphere is in general agreement with both our interferometric data and archival spectrophotometry.

This paper describes the video and audio tools that have been implemented in a real-type system to immerse a user into a virtual scene. The video tools include motion detection, skin detection by thresholding, shadow detection and extraction, and finally the user’s head and hands detection. Once this is done, the user (who is surrounded by a matrix of loudspeakers) is able to move a sound source in the horizontal plane around him. Moreover, the sound is auralized by convolution with (directional) room impulse responses, which have been pre-computed by a ray tracing method. The different sound contributions are distributed to the individual loudspeakers by applying the VBAP technique. [less ▲]

Using the FLUOR beam-combiner at the CHARA Array, we have obtained highprecision visibility measurements of Vega, a prototypic debris-disk star. The combination of long and short baselines has allowed us to separately resolve the stellar photosphere and the close environment of the star (< 8 AU). Our observations show a significant deficit in square visibility at short baselines with respect to the expected visibility of a simple uniform disk stellar model, suggesting the presence of an extended source around Vega. We propose that the excess emission is most likely due to the presence of hot circumstellar dust in the inner part of Vega's debris disk, with a flux ratio of 1.29 ± 0.19% between the integrated dust emission and the stellar photosphere. Using this information together with archival photometric measurements in the nearand mid-infrared, we derive the expected physical properties of the circumstellar dust by modelling its infrared Spectral Energy Distribution. The inferred properties suggest that the Vega system could be currently undergoing major dynamical perturbations. [less ▲]

We have obtained high-precision interferometric measurements of the A0 V standard star Vega with the Center for High Angular Resolution Astronomy (CHARA) Array and the Fiber Linked Unit for Optical Recombination (FLUOR) beam combiner in the K' band at projected baselines between 103 m and 273 m. The measured squared visibility amplitudes beyond the first lobe are significantly weaker than expected for a slowly rotating star and provide strong evidence for the model of Vega as a rapidly rotating star viewed very nearly pole on. We have constructed a Roche-von Zeipel gravity-darkened model atmosphere which is in generally good agreement with both our interferometric data and archival spectrophotometry. Our model indicates Vega is rotating at Ë 92% of its angular break-up rate with an equatorial velocity of Ë 275 km s[SUP]-1[/SUP]. We find a polar effective temperature of Ë 10150 K and a pole-to-equator effective temperature difference of Ë 2500 K, much larger than the Ë 300 K derived by Gulliver, Hill, and Adelman. Our model suggests that Vega's cool equatorial atmosphere may have significant convective flux and predicts a significantly cooler spectral energy distribution for Vega as seen by its surrounding debris disk. This work was performed in part under contract with the Jet Propulsion Laboratory (JPL) funded by NASA through the Michelson Fellowship Program. JPL is managed for NASA by the California Institute of Technology. The CHARA Array is operated by the Center for High Angular Resolution Astronomy with support from Georgia State University and the National Science Foundation, the Keck Foundation and the Packard Foundation.

A reduction of the carbonate-carbon to organic-carbon export rain ratio during glacial times is commonly advanced to explain an important part of the observed glacial-interglacial atmospheric CO2 variation. This hypothesis was tested and side-effects on the evolution of carbonate preservation/dissolution in the surface sediment explored with a multi-box model (MBM) of the ocean carbon cycle, fully coupled to a new transient advection-diffusion-reaction model (called MEDUSA) representing early diagenesis processes of carbonate minerals in the surface sediment. MEDUSA explicitly considers the role of organic matter remineralisation in the sediment column to enhance calcite (and aragonite) dissolution. It is fully bi-directional and takes chemical erosion into account in times when carbonate dissolution makes the sediment mixed-layer collapse faster than the sediment supply to the surface is able to counterbalance. Coupled model experiments were run for 240,000 years, forced by variable sea-level, temperature and salinity histories, and variable continental weathering inputs. Various scenarios for the evolution of the rain ratio over glacial to interglacial periods were adopted. A peak reduction of the rain ratio by 40% at the Last Glacial Maximum (LGM) was found to produce a net atmospheric pCO2 reduction of about 30ppm, on top of a 60ppm reduction produced by changing continental shelf carbonate accumulation and changing continental weathering inputs. The overall 90ppm oscillation compares well with the observed data. However, the effect on the model sedimentary record is clearly at odds with actual sediment records. The changes related to continental shelf processes and variable weathering flux depress the calcite saturation horizon by about 1km at the LGM; if rain ratio variations are also considered, that depression increases by another km. An assessment of the respective contributions from various model parameters will be presented. [less ▲]

In order to face the strong competitions of globalization and internationalization, modern enterprises require high quality logistics services for their economic interests, production requisites and market changes to enhance their competitive positions. In accordance with the sustainable socio-economic developments, the enterprises should comply with the social rules and regulations that aim at reducing the society costs such as congestion, pollution, and environmental protection. Intermodal transportation is an attractive solution for modern enterprises by offering economic, environmental friendly and door-to-door transport means that can easily be integrated into modern logistic chains. Making full use of the intermodal transport has become a strategic measure for many enterprises in their logistical organization, with many successful stories. However, the tendency of implementing intermodal transport has not been recognized well by certain enterprises. Some barriers and bottlenecks block the proper integration and organization of intermodal logistical chains, which are indispensable for the logistics of enterprises. In order to optimize the structure of transport system and to help enterprises implement modern and innovative technologies, a study was carried out in Belgium, with the representative characteristics of Western Europe, to identify the potential of utilizing intermodal transport and to search for the bottlenecks that break the logistical chains. This study supplies the decision makers and the enterprises useful suggestions to improve the intermodal transport services and the intermodal traffic. This paper will introduce main concepts and methods of this important study. [less ▲]

Comprendre la façon dont le cerveau travaille et en particulier le mode de communication de ses cellules est un rêve que beaucoup de chercheurs caressent. A l’heure actuelle, une des rares certitudes à son sujet est qu’un de ses modes de transmission d’informations utilise des « messagers » chimiques appelés neurotransmetteurs. Parmi ceux-ci, la sérotonine (5-HT) revêt une importance particulière. En effet, la 5-HT est impliquée dans de nombreuses fonctions (apprentissage, locomotion, sommeil,…) et pathologies (dépressions, démences, schizophrénies,…). Dès lors, l'étude in vivo chez l'homme des neurones sérotoninergiques ainsi que la quantification de la vitesse de biosynthèse de la 5-HT sont des domaines d'études fondamentaux pour lesquels la tomographie à émission de positons (TEP) constitue un outil de choix. Pour mener à bien ces différentes expérimentations, deux stratégies sont envisageables : - L’emploi d'un traceur capable de suivre la chaîne métabolique du tryptophane conduisant à la 5-HT tout en évitant les autres voies métaboliques. - L’utilisation d'un inhibiteur de la TrpOH (enzyme limitant du processus). Dans le cadre de cette présentation, nous nous intéresserons plus particulièrement à la deuxième stratégie. [less ▲]
