The fist lynx were seen in eastern Belgium at the end of the 1990s. Since then, both sightings and tracks have been recorded there and in the Ardenne (south east Belgium). Whether this presence indicates a spontaneous return of individuals deriving from the population reintroduced in Germany or results from illicit releases, it raises the question of the suitability and the carrying capacity of habitats in an area of dense human occupation. Using two software programs, a mapping model to assess habitat characterization, drawn from relevant criteria for this species, was tested to estimate the potential host of the study area, via the determination of areas of suitable habitats, and the dispersion potential of the species, through the identification of the most viable dispersal corridors. The findings of the study (multi criteria analysis of potential host of habitats, identification of corridors of lowest cost, estimation of the potential population...), compiled on the basis mapping model and simulations, suggest that a return of the lynx in Wallonia may be sustainable if supported and managed wisly by the regional administrative services.

Light elicits robust nonvisual effects on numerous physiological and behavioral variables, such as the human sleep-wake cycle and cognitive performance. Light effects crucially rely on properties such as dose, duration, timing, and wavelength. Recently, the use of methods such as fMRI to assess light effects on nonvisual brain responses has revealed how light can optimize brain function during specific cognitive tasks, especially in tasks of sustained attention. In this chapter, we address two main issues: how light impinges on cognition via consolidation of human sleep-wake cycles; and how light directly impacts on sleep and cognition, in particular in tasks of sustained attention. A thorough understanding of how light affects sleep and cognitive performance may help to improve light settings at home and at the workplace in order to improve well-being. [less ▲]

Allogeneic hematopoietic stem cell transplantation (HSCT) following myeloablative (conventional) conditioning regimen is associated with a high incidence of transplant-related morbidity and mortality, limiting its use to younger patients without medical co-morbidities. Over the past few years, it has become more evident that the alloreactivty of transplanted donor immunocompetent cells against host tumor cells (graft-versus-tumor effects, GVT effects) plays a major role in eradicating malignancies after allogeneic HSCT. Based on these observations, several groups of investigators have developed reduced intensity conditioning (RIC) regimens allowing patients who are ineligible for conventional HSCT to benefit from the potentially curative GVT effects of allogeneic transplantation. Retrospective studies have suggested that, in comparison with myeloablative allogeneic HSCT, in patient aged 40-60 years, RIC HSCT was associated with a higher risk of relapse but a lower incidence of transplant-related mortality leading to similar progression-gree and overall survivals. Prospective studies are ongoing to define which patients might most benefit from RIC HSCT, and to increase the anti-tumoral activity of the procedure while reducing the incidence and the severity of acute graft-versus-host disease (GVHD). In this article, we review the current status and perspectives of RIC HSCT. [less ▲]

Computer models are widely used to support the development of conventional design methods based on expensive full-scale tests or trial and error methods. Nevertheless, in order to accurately model metal forming processes as well as structural behavior of load carrying elements, it is necessary to afford an accurate knowledge of the material properties. Titanium is one of the material for which various industrial sectors such as aerospace or biomedical are showing an increasing interest. This paper presents the experimental tests performed on the titanium based alloy Ti6Al4V to investigate on its mechanical behavior, especially in terms of its anisotropy and hardening. For that purpose, a classical uniaxial and a non-standard biaxial experimental equipments designed by Florès in the Materials and Structures Mechanics Laboratory of the University of Liège have been used to perform tensile, simple shear and cyclic shear tests as well as successive simple shear and plane strain tests, which provide the main contribution of this paper in the form of stress-strain curves.

This chapter describes the state of the art in molecular recognition force spectroscopy performed by AFM. The different aspects of the topic are discussed, as the appropriate techniques for the functionalization of cantilever tips and for the preparation of (biological) samples. The principles of single-molecule force spectroscopy are then explained, together with exciting and recent examples on synthetic and biological samples. Finally, the main techniques to map molecular recognition interactions are reviewed and discussed in terms of performances. Novel and interesting applications illustrate the use of these imaging methods. [less ▲]

Endoleaks represent the most common complication of endovascular aortic aneurysm repair. With the increasing use of endovascular techniques for aortic aneurysm repair, the prevalence of endoleaks has risen. While maintaining pressurization of the aneurysm sac, endoleaks expose to persistent risks of an evolution towards rupture. Long-term surveillance with imaging studies is necessary to reduce the incidence of these specific complications that may require intervention. The objective of this article is to draw the attention to the possible occurrence of these complications and to report the elements of diagnosis and treatment. [less ▲]

Stability and convergence of the interior penalty (IP) discontinuous Galerkin method are closely related to the penalty coefficient sigma_f . Whereas Shahbazi [1] has derived nearly optimal values of sigma_f for elliptic problems (assuming a constant viscosity parameter), we propose a generalisation of this definition, in order to take into account mesh anisotropy on the one hand, and strong variations of the diffusivity on the other hand, typical for Reynolds-averaged Navier-Stokes models, in particular the Spalart-Allmaras model. The adequacy of this new definition is illustrated by the application to benchmark 2D computations. Finally, a comparison with two state of the art finite volume solvers is presented for a 3D high-lift cascade flow. [less ▲]

La dysphasie, définie comme un trouble spécifique du développement du langage, demeure encore très mal comprise aujourd'hui et continue d‟être au coeur de la réflexion de nombreuses études. Plusieurs hypothèses ont tenté d‟expliquer les difficultés des enfants atteints de ce trouble. Celle de la limitation des capacités de traitement, qui suggère un déficit de la vitesse de traitement ou de la mémoire de travail comme origine des troubles langagiers, en est un exemple intéressant. Et si les troubles morphosyntaxiques de ces enfants pouvaient être expliqués en termes de limitation des capacités de traitement ? Certains auteurs vont dans ce sens et c‟est ce que nous avons voulu évaluer dans notre étude. Pour cela, une tâche de compréhension morphosyntaxique a été créée. Dans ces phrases, trois facteurs influençant les ressources de traitement utilisées ont été manipulés : la fréquence lexicale des mots utilisés, la longueur des phrases et la réalisation d'une tâche interférente. Notre hypothèse suppose une dégradation plus importante des performances des enfants dysphasiques par rapport à celles des enfants contrôles suite à l'augmentation des demandes en ressources de traitement. Or, si les résultats obtenus nous permettent d'attester de la standardisation de notre tâche ; nous ne pouvons corroborer l'hypothèse de la limitation des capacités de traitement. En effet, des différences entre les groupes sont observées mais la chute de la performance des enfants dysphasiques escomptée n'est pas mise en évidence. Et quand nous nous attachons à comprendre les différences entre les trois groupes d'enfants, c'est une explication en termes de niveau langagier qui serait privilégiée. [less ▲]
