Our Working Group (WG) studies massive, luminous stars, both individually and in resolved and unresolved populations, with historical focus on early-type (OB) stars, A-supergiants, and Wolf-Rayet stars. Our group also studies lower mass stars (e.g., central stars of planetary nebulae and their winds) which display features similar or related to those present in massive stars, and thus may improve our understanding of the physical processes occurring in massive stars. In recent years, massive red supergiants that evolve from hot stars have been included into our activities as well. We emphasize the role of massive stars in other branches of astrophysics, particularly regarding the First Stars, long duration Gamma-Ray bursts, formation of massive stars and their feedback on star formation in general, pulsations of massive stars, and starburst galaxies.

This paper presents an overview of court practice in relation to Regulation 1346/2000. The focus is on cases decided by the ECJ, Belgian and French courts. Reference is also made to the most important cases decided by English courts. Cases are presented and discussed in relation to the various provisions of the Regulation to which they relate. For each case, an abstract is included, followed by (critical) comments. This overview appeared in a book presenting the main European regulations dealing with European procedural law (jurisdiction of courts, recognition and enforcement of foreign judgments). The book is part of a series edited by Prof. Georges de Leval (University of Liège), which collects court practice in relation to procedural law. [less ▲]

Nowadays, image processing and GIS tools are more accessible and available to all. Most of diachronical or historical studies use the image geometric correction with several documents like old maps, plans or aerial photographs. They are usually based on low-order polynomial equation to perfom these kinds of simplistic uses. Most of commercial softwares provide us a total or by ground control points RMSE but they don’t offer a overview of the spatial error distribution. More this does not guarantee that its significance for the other points of the image. Do not consider these errors can lead to erroneous observations and misinterpretations like historical moving streams or bank erosion rate. Using a least square adjustment (LSA), allow to recalculate the transformation equation from the pairs of control points coordinates. Assuming that residuals are spatially auto-correlated, we can build error vectors whose direction and magnitude symbolize the error at each point of the image. By another way, LSA manage the precision during transformation process by using a stochastic model in addition of the mathematical model during the transformation. This gives us variance on parameters of the transformation. Knowing the precision of all elements and variance/covariance matrix on transformation parameters, we apply variance propagation on the model. As an output, we obtain confidence ellipses on each transformed points, thus a spatial distribution of error for the entire image. Moreover, this leads us to determine statistically if observed movement are significant or not. The represent error is a complex problem that cannot be solved with a quick fix. In this work, we present an interesting example of using well-known topographic methods to solve image processing problems. [less ▲]

The role of active vs. passive ERP paradigms in disorders of consciousness is assessed in this case study of a LIS patient. Results show that despite absent P3 in a passive auditory task, the patient displayed significant differences in the active task. This study shows the importance of using a large battery of tests when assessing DOC patients. [less ▲]

Background: Motor fatigue and ambulation impairment are prominent clinical features of people with multiple sclerosis (pMS). We hypothesized that a multimodal and comparative assessment of walking speed on short and long distance would allow a better delineation and quantification of gait fatigability in pMS. Objectives: To compare 4 walking paradigms: the timed 25-foot walk (T25FW), a corrected version of the T25FW with dynamic start (T25FW+), the timed 100-meter walk (T100MW) and the timed 500-meter walk (T500MW). Methods: Thirty controls and 81 pMS performed the 4 walking tests in a single study visit. Results: The 4 walking tests were performed with a slower WS in pMS compared to controls even in subgroups with minimal disability. The finishing speed of the last 100-meter of the T500MW was the slowest measurable WS whereas the T25FW+ provided the fastest measurable WS. The ratio between such slowest and fastest WS (Deceleration Index, DI) was significantly lower only in pMS with EDSS 4.0-6.0, a pyramidal or cerebellar functional system score reaching 3 or a maximum reported walking distance !4000m. Conclusion: The motor fatigue which triggers gait deceleration over a sustained effort in pMS can be measured by the WS ratio between performances on a very short distance and the finishing pace on a longer more demanding task. The absolute walking speed is abnormal early in MS whatever the distance of effort when patients are unaware of ambulation impairment. In contrast, the DI-measured ambulation fatigability appears to take place later in the disease course. [less ▲]

In this paper we trace some of the key points in the history of Science and Technology Studies (STS). In particular we outline the inherently political dynamics of the field. Against We underline two emerging patterns in the curse of STS: the one of “depoliticisation” and the one of increasing “engagement”. We address the case study nanotechnologies and discuss their intertwined history with the STS. This allows us to point at the risk that the increasing institutionalisation of STS and the political mandate that frames and stabilizes the field’s relationship to the technological developments would create a political void. We conclude that STS research is at a crossroads. It is facing an important empirical turn, which may deprive it from its political significance, and constantly redefine its institutional constraints. STS has to continuously question its underlying political assumptions (as it occurs more and more regarding public participation) and to make it explicit. [less ▲]

What will be the European ecosystem responses to future climate? With unprecedented speed and extent, the projected climate change might lead to a disruption of terrestrial plants functioning in many regions. In the framework of the EcoChange project, transient projections over the 1901-2100 period have been performed with a process-based dynamic vegetation model, CARAIB DVM (Dury et al., 2011, iForest 4: 82, 99). The vegetation model was driven by the outputs of four climate models under the SRES A1B scenario: the ARPEGE/Climate model and three regional climate models (KNMI-RACMO2 , DMI-HIRHAM5 and HC-HadRM3Q0 RCMs) from the European Union project ENSEMBLES. DVMs are appropriate tools to apprehend potential climate change impacts on ecosystems and identify threatened regions over Europe. CARAIB outputs (soil moisture, runoff, net primary productivity, fire, etc.) were used to characterize the ecosystem evolution. To assess consequences on biodiversity, the evolution of 100 natural common European species (47 herbs, 12 shrubs and 41 trees) has been studied year-to-year over the 1901-2100 period. Under the combined effects of projected changes particularly in temperature and precipitations, CARAIB simulates important reductions in the annual soil water content. The species productivities vary strongly from year to year reaching during the driest years values much lower than present-day average productivity. According to CARAIB, a lot of species might go beyond their water tolerance very frequently, particularly after 2050, due to more intense summer droughts. In the northern part of Europe and in the Alps, with reduced temperature variability and positive soil water anomalies, NPP variability tends to decrease. Regions with more severe droughts might also be affected by an increase of the frequency and intensity of wildfires. With this background, the species distributions might be strongly modified. 15% of tree species and 30% of herb and shrub species (respectively 30% and 60% if the CO2 fertilization effect on species is not taken into account) might experience a loss of 30% or more of their current distribution. Proportions of new species appearance at the end of the century were also studied. Southern Europe might suffer important species extinction while the more suitable climate conditions in northern Europe might lead to a gain in species diversity. [less ▲]

L’efficience des rations alimentaires à base de feuilles séchées de manioc doux a été évaluée en alimentation des poulettes pendant seize semaines. Trois rations contenant 0% (R0), 5% (R5) et 10% (R10) de feuilles séchées de manioc ont été utilisées pour nourrir 225 poussins d’un jour de souche ISA Brown répartis en groupe de 25 poussins avec trois répétitions par ration. Les gains de poids moyen quotidien (8,5 à 9,2 g/j) et les indices de consommation (IC = 7,0 à 7,58) sont similaires (P > 0,05) pour toutes les rations alimentaires. L’incorporation des feuilles, n’a pas empêché d’atteindre les besoins nutritionnels recommandés aux poulettes. Ainsi, les rations à base de feuilles séchées de manioc, n’ont pas influé sur le taux de mortalité des poulettes. Mais, elles ont permis de réduire significativement (P < 0,05) le coût alimentaire. Par rapport à la ration R0, le coût alimentaire global a baissé de 11,5% et 7,4% respectivement pour les rations R5 et R10. Sur les deux phases expérimentales, les meilleures performances bioéconomiques ont été enregistrées chez les poulettes ayant reçu la ration contenant 5% de feuilles. [less ▲]
