Two trials were conducted to evaluate the effect of rumen-degradable protein balance (OEB) deficit on voluntary intake (trial 1), microbial protein synthesis, andNmetabolism (trial 2) in growing doublemuscled Belgian Blue bulls. In trial 1, six bulls (339 ± 26 kg of initial BW) were used in a replicated 3 × 3 Latin square and received a diet of 60% corn silage and 40% concentrate with ad libitum intake (DM basis). Three concentrates were formulated by adding urea at the expense of barley to give similar dietary contents of intestinal digestible proteins, NE for fattening, and fermentable OM, but with different levels of OEB. Thus, 2 levels of OEB deficit (−23.7 and −9.2 g of OEB/kg of DM) were compared with a diet providing a slight OEB surplus (5.3 g of OEB/kg of DM). Voluntary DMI decreased linearly (P = 0.02) with decreasing rumen-degradable protein balance. This decrease in intake could explain the linear decrease in ADG observed when negative OEB diets were fed. In trial 2, six bulls (304 ± 12 kg of initial BW) with cannulas in the rumen and proximal duodenum were used in a replicated 3 × 3 Latin square and fed diets similar to those used in trial 1 at an intake level of 85 g of DM/kg of BW0.75. Diurnal variations of ruminal NH3-N and plasma urea-N concentrations were greatly influenced by the level of OEB in the diet. No differences in NDF and starch degradation in the rumen, microbial N flow at the duodenum, or efficiency of microbial protein synthesis in the rumen were noted among the levels of OEB in diets. The reductions of the OEB value from 5.3 g/kg of DM to −9.2 g/ kg of DM and −23.7 g/kg of DM were associated with reductions of 26.5 and 48.8% in urinary Noutput. Absolute amounts of N retained by the bulls increased significantly with the level of OEB in diets. Indeed, 51.4% of the incremental supply of N was excreted between −23.7 and −9.2 g of OEB/kg of DM diets, and 74.6% of the incremental supply of N was excreted between −9.2 and 5.3 g of OEB/kg of DM diets. Feeding diets characterized by an adequate intestinal digestible protein supply and a OEB close to −10 g of OEB/kg of DM could be a feeding strategy to reduce N losses from the farm with little effect on the animal performance and voluntary intake. Reduced OEB may reduce N excretion in the environment but may also result in decreased N retention. [less ▲]

The RS-PDM© model generates flows in time series on the basis of observed rainfall after self-calibration which is based on short period of observed rainfall and flow. This is done with daily or hourly data. The study highlights the capacity of the RS-PDM© model to simulate extreme flows in poorly gauged basins in Walloon region on the basis of observed rains and of a short period of observed flows. Concerning the time series, it was highlighted an important dispersion of the flows simulated for a given observed flow even for daily or hourly data. The Nash criteria varied between 0.59 and 0.92. However, the flows simulated via RS-PDM© make it possible to adjust a statistical distribution of extremes flows (Gumbel law) close to the statistic obtained with a long period of gauging. So, if the simulations realized by mean of this model present poor to acceptable performances concerning the time series simulations, they permit to obtain rapidly quite good statistics of extremes flows on the basis of a short gauging period.

Results from a regional climate simulation (1970–2006) over the Greenland ice sheet (GrIS) reveals that more than 97% of the interannual variability of the modelled Surface Mass Balance (SMB) can be explained by the GrIS summer temperature anomaly and the GrIS annual precipitation anomaly. This multiple regression is then used to empirically estimate the GrIS SMB since 1900 from climatological time series. The projected SMB changes in the 21st century are investigated with the set of simulations performed with atmosphere-ocean general circulation models (AOGCMs) of the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4). These estimates show that the high surface mass loss rates of recent years are not unprecedented in the GrIS history of the last hundred years. The minimum SMB rate seems to have occurred earlier in the 1930s and corresponds to a zero SMB rate. The AOGCMs project that the SMB rate of the 1930s would be common at the end of 2100. The temperature would be higher than in the 1930s but the increase of accumulation in the 21st century would partly offset the acceleration of surface melt due to the temperature increase. However, these assumptions are based on an empirical multiple regression only validated for recent/current climatic conditions, and the accuracy and time homogeneity of the data sets and AOGCM results used in these estimations constitute a large uncertainty.

In this paper, we study strong uniform consistency of a weighted average of artificial data points. This is especially useful when information is incomplete (censored data, missing data ...). In this case, reconstruction of the information is often achieved nonparametrically by using a local preservation of mean criterion for which the corresponding mean is estimated by a weighted average of new data points. The present approach enlarges the possible scope for applications beyond just the incomplete data context and can also be useful to treat the estimation of the conditional mean of specific functions of complete data points. As a consequence, we establish the strong uniform consistency of the Nadaraya - Watson [Nadaraya, E.A., 1964. On estimating regression. Theory Probab. Appl. 9, 141 - 142; Watson, G.S., 1964. Smooth regression analysis. Sankhya Ser. A 26, 359 - 372] estimator for general transformations of the data points. This result generalizes the one of Hardle et al. [Strong uniform consistency rates for estimators of conditional functionals. Ann. Statist. 16, 1428 - 1449]. In addition, the strong uniform consistency of a modulus of continuity will be obtained for this estimator. Applications of those two results are detailed for some popular estimators.

Because of the strong coupling between mechanical and electrical phenomena existing in electromechanical microdevices, some of them experience, above a given driving voltage, an unstable behavior called pull-in effect. The present paper investigates the application of topology optimization to electromechanical microdevices for the purpose of delaying this unstable behavior by maximizing their pull-in voltage. Within the framework of this preliminary study, the pull-in voltage maximization procedure is developed on the basis of electromechanical microbeams reinforcement topology design problem. The proposed sensitivity analysis requires only the knowledge of the microdevice pull-in state and of the first eigenmode of the tangent stiffness matrix. As the pull-in point research is a highly non-linear problem, the analysis is based on a monolithic finite element formulation combined with a normal flow algorithm (homotopy method). An application of the developed method is proposed and the result is compared to the one obtained using a linear compliance optimization. Moreover, as the results provided by the developed method do not comply with manufacturing constraints, a deposition process constraint is added to the optimization problem and its effect on the final design is also tested.

The transition towards sustainable development is tackled by the “deliberative research” approach. The involvement of researchers in the collective action, obliges them to build new relations between research and actors, making the research relevant regarding the identified stakes. The approach – in this case of an organic beef food chain – starts by an identification step of concerns and viewpoints. The analysis leads on one hand to a proposal of action, which reconfigures the relations and stabilizes intermediary objects and on the other hand to research proposals which are intended to give answers to issues related to the action. These researches are related to different models according the way they associate actors and objects. Their outcomes feed the running action and open to a new food chain "référentiel" (frame of reference) Résumé français [less ▲]

La bibliothèque imaginée par Aby Warburg est à plusieurs égards le reflet d'une pensée parmi les plus originales que l'histoire de l'art ait connu. On connaît généralement cette bibliothèque grâce au témoignage d'Ernst Cassirer qui voyait s'y déployer un "ensemble de problèmes". Le philosophe ne cache pas l'angoisse qu'il ressentit d'abord face à ce labyrinthe de livres dont l'organisation lui échappait. Warburg avait fait graver à l'entrée de sa bibliothèque le mot Mnemosyne, "mémoire" en grec. Il considérait lui-même la bibliothèque comme son oeuvre la plus importante. L'ordre de classement des livres, qu'il révisait presque chaque jour, devait sembler chaotique pour qui n'était pas familier de l'"espace de pensée" (Denkraum) warburgien. Pas de classement par discipline ou de classement chronologique, mais un classement thématique qui obéissait à la "loi de bon voisinage". La bibliothèque Warburg, immense fonds de mémoire culturelle où les savoirs se décloisonnaient, accompagnait la recherche de manière inédite. véritable laboratoire pratique où le savoir était mis à l'épreuve, la salle de lecture en ellipse constituait comme une "arène" où les chercheurs mettaient à profit les livres et leur agencement si particulier.

Cet article vise à proposer une grille de lecture pour les chapitres de l'ouvrage. Elle organise les paradigmes dont ils traitent sur un spectre, en l'occurrence épistémologique, jalonné de quelques grands courants qui ont marqué les sciences sociales au 20e Siècle. Tracer un tel spectre permet de suggérer une première porte d'entrée simplifiée dans ce champ vaste et toujours en friche des théories sociologiques sans pour autant résoudre des oppositions à l'évidence irréductibles. Il s'étend d'un pôle que nous qualifierons de «aprioriste» au pôle « constructiviste » qui égraine les « nouvelles sociologies », dont parle aussi P. Corcuff, sans pour autant regrouper sous ce dernier vocable les mêmes paradigmes. Dans une version totalement purifiée qui ne correspond pas en tant que telle à un paradigme donné, le premier pôle serait celui d'une sociologie cherchant à déterminer ce qui fonde le monde social comme étant un donné a priori, c'est à dire précédant et surtout conditionnant l'expérience que les acteurs sociaux ont du monde en général et les représentations qu'ils s'en font en déposant eu eux ses traces. Le second serait l'idéal-type d'une sociologie n'envisageant ce même monde que comme un lacis de représentations construites à partir de points de vue distincts au sujet desquels il importe peu de savoir si ce qui les a constitué en tant que point de vue résulte des influences de tel ou tel type de monde social. Ce qui importe est, pour ainsi dire, le sens a postériori que ces points de vue concèdent au monde, aux objets, aux personnes et au relations qui tentent de se stabiliser différentes entités. On peut estimer que les paradigmes aprioristes s'inscrivent dans une reprise du projet métaphysique kantien lequel cherche à définir les conditions de possibilités de la connaissance et de la pensée humaine. Mais ils le font dans un cadre et avec des objectifs considérablement renouvelés par rapport à l'humanisme du XVIIIe siècle. Dans notre hypothèse, la tâche consistant à découvrir l'a priori qui conditionne ce que nous pensons et faisons serait depuis le XXe Siècle davantage assignable aux sciences sociales qu'à la philosophie. Les sociologies de l'a priori cherchent à fonder socialement les modes de connaissances nous permettant d'appréhender le monde et ses objets là où la philosophie moderne les fondait subjectivement. Leur but ultime est d'établir les formes et les catégories sociales qui sont au principe de l'action des acteurs et qui constitueraient d'une certaine manière la paire de lunette au travers de laquelle ils percoivent le monde. Ainsi, la sociologie critique de Bourdieu, la sociologie de l'action de Touraine ou encore la sociologie de l'action publique pourraient être envisagées comme relevant d'une démarche davantage aprioriste que les autres. A l'autre bout du spectre sur lequel se placent les paradigmes abordés par cet ouvrage, se situent le pôle constructiviste et le relativisme qui en est la forme extrapolée. Les constructivistes, envisagent leur démarche comme un fine traduction de la manière dont les personnes et leurs bagages cognitifs (savoirs, stratégies, valeurs morales, etc.) s'y prennent pour construire et stabiliser un (ou des) monde(s) commun(s). Leur espace de problématisation évolue assez loin de la question de savoir quels sont les a priori sociaux qui nous conduisent à penser comme nous pensons et à agir comme nous agissons. En réalité, il s'agit de déplacer complètement le regard des conditions de l'action à l'action elle-même en la déployant sa multidimensionnalité. [less ▲]

Destruction and fragmentation of natural and semi-natural habitats are considered as major threats for plant species richness. However, the response of plant species richness to habitat alteration is sometimes delayed. This delay induces an extinction debt in plant communities that are thus prone to undergo species extinctions in the following years. Several methodologies were proposed to detect this extinction debt and estimate the mean number of species yet to disappear. In this study, we developed a new methodology for the estimation of the extinction debt extent. Moreover, we proposed a species approach aimed at determining which species are more sensitive to extinction as a consequence of habitat destruction and fragmentation. Finally, we explored the colonization ability of habitat specialist species. This aspect is of fi rst importance to counteract local species extinctions. Our model habitat is calcareous grasslands of Southeast Belgium that have suffered an important fragmentation process since the beginning of the twentieth century. We estimated that the mean extinction debt of the calcareous grassland patches was ca. 24 species, including ca. six specialist species. We showed that 16 of the 46 specialist species did not meet their area requirement anymore and were therefore considered as sensitive to extinction. However, the species composition of the more recent grasslands indicates a non-negligible recolonization potential of specialist species. There is thus a real possibility to reduce extinction risk by restoring suitable habitats. [less ▲]

Lymphangiogenesis, the formation of new lymphatic vessels, is associated to numerous pathologies1 and understanding the molecular and cellular basis of this complex process is essential for the development of novel therapeutic strategies. Studies on lymphangiogenesis have been hampered by difficulties in culturing lymphatic capillaries as three-dimensional (3D) structures in vitro that mimic the in vivo features of lymphatic vessels and lymphangiogenesis. The lymphatic ring assay described here phenocopies the different steps of lymphangiogenesis, including the spreading from a preexisting vessel, cell proliferation, migration and differentiation into capillaries. It consists on the adaptation of the aortic ring assay that has proved to be useful to investigate the molecular basis of angiogenesis2-4. The lymphatic ring model is an ideal assay for testing the activity of lymphangiogenic agonists or antagonists. The absence of inflammatory cells allows a simple interpretation of results and the determination of direct effects of compounds on lymphatic endothelial cell properties. Another advantage of the lymphatic ring assay is that cell outgrowing are primary cells which have not been modified by repeated passages or immortalization. This culture model bridges the gap between in vitro and in vivo studies and allows genetic analysis by using thoracic ducts from genetically modified mice. [less ▲]

Plasminogen activator inhibitor-1 (PAI-1) paradoxically enhances tumor progression and angiogenesis; however, the mechanism supporting this role is not known. Here we provide evidence that PAI-1 is essential to protect endothelial cells (ECs) from FasL-mediated apoptosis. In the absence of host-derived PAI-1, human neuroblastoma cells implanted in PAI-1-deficient mice form smaller and poorly vascularized tumors containing an increased number of apoptotic ECs. We observed that knockdown of PAI-1 in ECs enhances cell-associated plasmin activity and increases spontaneous apoptosis in vitro. We further demonstrate that plasmin cleaves FasL at Arg144-Lys145, releasing a soluble proapoptotic FasL fragment from the surface of ECs. The data provide a mechanism explaining the proangiogenic activity of PAI-1. [less ▲]

The increasing diversity in both substrates and functions of matrix metalloproteinases (MMPs) makes these enzymes central regulators in the complex tumor ecosystem composed of cancer cells and their microenvironment. In the majority of cancers, membrane-associated and extracellular proteases are mainly produced by host cells including inflammatory cells, endothelial cells, pericytes and fibroblasts. Recent data based on in vitro and in vivo studies have demonstrated the relevance of these enzymes in multiple processes controlling cancer growth, angiogenesis and metastatic dissemination.

This work details for the first time the sedimentology of Les Monts de Baileux section. This section, located in a quarry between Chimay and Couvin, exposes a remarkable succession of strata from the top of the Jemelle Formation to the base of the Mont d’Haurs Formation. It therefore offers the opportunity to investigate the entire Hanonet, Trois- Fontaines and Terres d’Haurs formations, biostratigraphically from Polygnathus ensensis to P. timorensis conodont zones. This large lithostratigraphic thickness of clayley and argillaceous, and also pure limestones encompasses the Eifelian/ Givetian boundary in the lower part of Hanonet Formation, allowing a better understanding of the transition between the Eifelian which corresponds to a mixed siliciclastic-carbonate detrital ramp and the lower Givetian dominated by a carbonate rimmed shelf-related sedimentation. Petrographic study leads to the definition of 21 microfacies integrated into two palaeogeographical models. The first model (13 microfacies) is proposed for the Jemelle, Hanonet and Trois-Fontaines formations, i.e. P. ensensis Zone and almost entire P. hemiansatus Zone. In this platform model, the fore-reef environment is characterized by a high influence of storm events and carbonate input coming from proximal settings. The reef is mainly composed of an accumulation of stromatoporoids, crinoids, tabulate corals and rugose corals with a peloidal matrix. The back-reef area is dominated by agitated environments and calmer lagoons. Locally, less agitated conditions allow growth of massive and laminar organisms. The second model (6 microfacies) concerns the Terres d’Haurs Formation with the end of P. hemianstus Zone and significant part of the P. timorensis Zone. This ramp model is divided into a mid-ramp characterized by open-marine sedimentation interrupted by storm-related events and an inner ramp composed of ooidal shoals, back-shoal sedimentation and storm related deposits. Two other microfacies are fragmentarily defined for the Mont d’Haurs Formation, within the main P. varcus / P. rhenanus intervals. This unit was affected by strong dolomitization processes, where scarcity of well preserved, primary sedimentary fabrics is not favourable for designing of a microfacies-based model at all. The last part of the work concerns stratigraphic variations of magnetic susceptibility (MS). Values of mass MS of rocks were plotted and juxtaposed with semi-quantitative variation curves of microfacies. According to the prevailing magnitudes of MS, the relationships with two controlling parameters are evaluated: terrigenous influence (using the thin-section data on detrital quartz contents as proxies) and wave agitation (based on microfacies interpretation). The transgressive- regressive evolution of microfacies characteristics are compared with the juxtaposed trends in decreasing-increasing MS magnitudes. Approximately two thirds of this section suggests a good matching of the trends on generalized lithological and magnetic data. It is explained by common presence of clayey/silty impurities of slightly to moderately varying compositions which are greatly evidenced by means of thin-section studies and represent a principal and abundant paramagnetic component. The overall MS magnitudes actually show decreasing trends together with vigorous, eustatically driven sealevel rises. However, the remaining third of intervals in this section shows the rather complex than simple, equivocally or negatively arranged sequence/lithologic and MS stratigraphic trends. [less ▲]
