[more ▼] We present a mid-term report on a project aimed at partially identifying the main modes of pulsation in the rapidly pulsating subdwarf B star PG 1047+003. Using the unique HIT-MS mode on FORS2 at the VLT we obtained ˜3000 spectra spread over 4 consecutive half-nights with a typical sampling rate of 20 s. These will be used to extract monochromatic pulsation amplitudes and phases that can be fit to model predictions in order to determine the degree ℓ of the mode in question.

[more ▼] The flow properties of powders are mainly due to the interplay of cohesive forces and intergrain frictional forces. We have experimentally investigated a "smart granular system" for which the interparticle cohesion can be tuned by a magnetic field B. We show that the rheological features of such a system can be controlled. Indeed, the granular flow can be controlled or even stopped by the magnetic field. Depending on the orientation of B, different dynamical regimes can be obtained like a "dry liquid state" forming conical droplets as well as a "layered soft state". Scaling lows are given for the flow rate outside a funnel as a function of B and for the stopping threshold of the flow as a function of the funnel output diameter D. From this analysis, it appears that the flowing properties are related to the dimensionality of the magnetic aggregates.

[more ▼] Infantile pyknocytosis (IP) is a rare hematological entity of newborns. It is a form of hemolytic anemia with unusual red cell morphology: the red blood cells are distorted, irregular, and small with many projections. Spontaneous resolution usually occurs by 4-6months of age. OBSERVATION: We describe the clinical features and biological parameters of 5 cases of IP. The first symptoms were always early jaundice, which required phototherapy. Anemia was severe in all babies and red blood cell transfusion was needed. CONCLUSION: IP is a rare cause of neonatal anemia whose diagnosis is based on a careful peripheral blood smear examination. In our study, anemia was severe and required red blood cell transfusion. Ethnic specificity and familial occurrence are reported in our experience.

[more ▼] We address the problem of finding indirect overlay paths that reduce the latency between pairs of nodes in an overlay. To this end we propose to rely on an Internet Coordinate System (ICS), namely Vivaldi, to estimate RTTs and help find these interesting detours. We define two initial criteria to illustrate our approach and assess their true/false positive rates.

[more ▼] Most Aphidinae species produce and use (E)-ß-farnesene (Eßf) as an alarm pheromone. This sesquiterpene is released by individuals under attack by a predator, and nearby aphids exhibit a variety of alarm behaviours. This PhD thesis aims to better understand how aphids manage their production and emission of alarm pheromone (Chapter IV). We also wanted, in a second step, to improve our knowledge on the roles that Eßf could play in the relationships that aphids have with their predators (Chapter V) and tending ants (Chapter VI), in order to better pinpoint the problem in this very tough context. The aphid predators have indeed a real advantage to be able to use the odorant cues emitted by their prey, to locate them and to select an adequate oviposition site. Ants establish with certain aphid species mutualistic relationships, which occurrence could be facilitated by the use of aphids’ odours. In Chapter IV, we have highlighted that aphid colonies non subjected to attack by predators release constantly small quantities of Eßf in their headspace, which means that this molecule could have additional roles than just acting as an alarm pheromone. In a second study, we demonstrated that the release of Eßf was not contagious, and therefore that a non stressed aphid receiving the alarm signal does not release additional Eßf. Since the production of alarm pheromone is likely to entail physiological cost, we tested and validated the hypothesis that aphids regulate their Eßf production according to their social environment. In Chapter V, we studied the ability of the hoverfly predator Episyrphus balteatus (Diptera, Syrphidae) to be used as biological control agent against aphids infesting tomato plants (Lycopersicon esculentum). After identifying the odours emitted by aphid infested plants, we have demonstrated that although this Diptera is able to perceive all the odours released by the system, it mainly uses Eßf to select its oviposition site. However, the E. balteatus larvae are not adapted to the architecture of tomato plants. We also showed that the Asian ladybeetle Harmonia axyridis (Coleoptera, Coccinellidae) olfaction was adapted to the perception of Eßf and that this beetle is also attracted by this sesquiterpene. Finally, in Chapter VI, we characterized the benefits accruing to aphid populations that have established mutualistic relationships with Lasius niger (Hymenoptera, Formicidae), and have demonstrated the role of Eßf and honeydew, respectively in locating aphid colonies and in the persistence of the mutualism.

[more ▼] In an experimental design, we asked 234 French-speaking Belgian university students to “draw Belgium”. No other guidelines were given. In addition to this request, the students were asked to fill in a 19-question questionnaire about their federal perceptions and preferences as well as political and socio-demographic indicators. This experimental research is an attempt to capture the relationships between representations and perceptions of federalism in Belgium. This short preliminary report offers the first results and insight from this research. Further analyses and publications will follow.

[more ▼] This paper studies the coordinated motion of a group of agents evolving on a Lie group. Left- or right-invariance with respect to the absolute position on the group lead to two different characterizations of relative positions and two associated definitions of coordination (fixed relative positions). Conditions for each type of coordination are derived in the associated Lie algebra. This allows to formulate the coordination problem on Lie groups as consensus in a vector space. Total coordination occurs when both types of coordination hold simultaneously. The discussion in this paper provides a common geometric framework for previously published coordination control laws on SO(3), SE(2) and SE(3). The theory is illustrated on the group of planar rigid motion SE(2).

[more ▼] La cathédrale de Laon comporte le plus grand ensemble sculpté de la fin du XIIe siècle: trois portails et leurs gâbles, deux fenêtres à voussures, de nombreuses têtes dans les écoinçons des baies, des personnages sur les arcs-boutants et des boeufs énigmatiques aux sommets des tours du massif occidental. L’ouvrage révèle un programme d'ensemble selon lequel les thèmes des portails latéraux - Incarnation et Jugement dernier - sont couronnés et achevés par le Triomphe de la Vierge au portail central, symbole de l'espoir eschatologique des chrétiens. Ce programme est attribué à Gautier de Mortagne, évêque de Laon de 1155 à 1174. Il est amplifié par les thèmes novateurs des fenêtres - Arts libéraux et Arts mécaniques au nord, Création-Rédemption au sud – lesquels procèdent directement des écrits de Hugues de Saint-Victor (1096-1141), théologien majeur du XIIe siècle avec qui Gautier de Mortagne entretenait des relations suivies. La présence des boeufs en haut des tours peut alors s'interpréter comme une introduction oculaire à ce programme: rappel de l'apparition providentielle d'un boeuf auprès d'un ouvrier lors de la construction de la cathédrale et herméneutique de ce miracle comme conjugaison nécessaire des oeuvres humaines et de la grâce divine. Les analyses iconographique, stylistique et archéologique ont permis plusieurs découvertes : l’existence d’une chapelle axiale dans le choeur primitif (détruit au début du XIIIe siècle), le remploi d’un portail complet datant de la toute fin de l'épiscopat de Barthélemy de Joux (1113-1151) et achevé avant le début de la construction de la cathédrale actuelle. La richesse et l’originalité de cet ensemble sculpté sont servies par une couverture photographique inédite présentée sous forme de corpus dans le CD-ROM interactif qui accompagne l’ouvrage. La critique d’authenticité, complétée par l’analyse de chaque sculpture du corpus, met en évidence un nombre significatif de têtes du XIIe siècle et dénote le bon état général de la sculpture originale. L’étude stylistique, couplée à celle des techniques d’exécution, permet de distinguer les manières d’un nombre réduit d’artistes : celui du portail de remploi, celui du choeur primitif et des clefs de voûte de la nef, l’artiste principal de la façade (manière A) et des arcs-boutants de la nef, et enfin celui de la manière B de la façade. L’auteur montre que ce dernier ira ensuite accomplir le décor sculpté de l’abbatiale Saint-Yved de Braine. La chronologie du chantier conduit à remonter quelque peu la datation de la sculpture de la façade au cours du dernier quart du XIIe siècle. Laon s’intègre dans le style antiquisant, appelé par commodité << style 1200 >> et devient une référence déterminante pour Chartres, Lausanne et Maastricht. Plus largement, l’écho qu’en offrent les ensembles sculptés de Paris, Reims et Amiens font incontestablement de Laon un grand chantier européen.
