The β Cephei pulsating stars present a unique opportunity to test and probe our knowledge of the interior of massive stars. The information that we can get depends on the quality and number of observational constraints, both seismic and classical ones. The asteroseismology of β Cephei stars proceeds by a forward approach, which can result in multiple solutions, without clear indication on the level of confidence. We seek a method to derive confidence intervals on stellar parameters and investigate how these latter behave depending on the seismic data accessible to the observer. We realise forward modelling with the help of a grid of pre-computed models. We also use Monte-Carlo simulations to build confidence intervals on the inferred stellar parameters. We apply and test this method in a series of hare and hound exercises on a subset of theoretical models simulating observed stars. Results show that a set of 5 frequencies (with knowledge of their associated angular degree) yields precise seismic constraints. Significant errors on the determination of the extent of the central mixed region may result when the theoretical models do not present the same chemical mixture as the observed star. [less ▲]

The knowledge of the tridimensional structure of a protein is essential to study its interactions and understand its mode of action. The Purpose of our work is to quickly and easily determine the structure of proteins using the backbone chemical shifts. Backbone chemical shifts data are NMR parameters that can be rapidly, easily and accurately measured. This parameter is very sensitive to the conformation of amino acids and is used to deduct the secondary structure (TALOS, RCI,...). We therefore plan to use backbone chemical shifts as constraints on dihedral angles to quickly and easily determine protein structure. Several « de novo » methods like CS-Rosetta , CS23D et CHESHIRE have been recently developed in this purpose. We will use proteins of different sizes for which, the structure (X-ray or NMR structure) and chemical shifts backbone are available for testing the three softwares. Knowing that each of these softwares predicted a large number of low energy models on the one hand, and that the deployment and use of these tools constitutes obstacles for users who are not experts in computer science on the other hand, our goal will be to develop a platform that can easily compare these three methods based on quality of the structure produced.

To date, only a few studies have applied metagenomics to investigate the influence of different tillage regimes and types of crop residue management on soil microbial communities. These studies were conducted under specific climates on soils characterized by particular land-use histories. A very different ecological context is to be found in certain areas of Western Europe, such as central Belgium, whose loess-derived soils are among the most fertile in the world and have long been used for intensive agriculture. Specific objectives were to determine diversity levels and changes in microbial community composition under different combinations of tillage regime (conventional vs. reduced) and crop residue fate (residue removal R- vs. residues left R+ on the field). As reduced tillage results in two contrasting zones (the first centimeters of soil are mixed each year, while the soil below remains unperturbed), we chose to perform the analysis at two depths: 0 to 5 cm and 15 to 20 cm.

Tree species influence biogeochemical cycling through element deposition (throughfall, litterfall), root decomposition and exudates, and through their influence on the microbial activities in the soil. Yet, the effect of mixing tree species on soil functioning is unclear, in particular concerning the microbial diversity and activity in soils. Here we synthesize results from the Exploratory Platform of the FunDivEUROPE project (http://www.fundiveurope.eu/). This network of 209 comparative plots covering tree diversity levels of 1 to 5 species was established in existing mature forests in 6 European regions. These six focal regions represent a gradient of major European forest types from boreal to Mediterranean forests. The aims of this study were to determine the soil microbial biomass and metabolic diversity of soil bacteria for these 6 European forest regions, presenting each a tree species richness gradient and to analyse the impact of tree species richness and the role of other controlling factors. We analysed the relation between tree species diversity, the proportion of coniferous tree species and soil factors (pH, soil organic carbon, water soluble carbon and nitrogen) and the carbon substrate utilisation pattern of soil bacteria (BIOLOG Ecoplate), soil microbial biomass (fumigation-extraction), hot water carbon and nitrogen in the forest floor and the upper mineral soil horizon (linear mixed models, GLM for multivariate abundance data, discriminant correspondence analysis). Mean values of microbial biomass carbon ranged from 3264 (Italy) to 8717 (Finland) mg kg-1 in the forest floor and from 465 (Italy) to 3748 (Finland) mg kg-1 in the mineral soil. Statistical models predicted microbial biomass to increase in both soil layers by 7-8% with each step increase in tree diversity. Increased proportion of conifers was linked to a decrease in the number of carbon substrates used by soil bacteria. The types of carbon sources used were dependent on region, proportion of conifers, soil pH and water-soluble carbon and nitrogen. [less ▲]

Using deep neural nets as function approximator for reinforcement learning tasks have recently been shown to be very powerful for solving problems approaching real-world complexity. Using these results as a benchmark, we discuss the role that the discount factor may play in the quality of the learning process of a deep Q-network (DQN). When the discount factor progressively increases up to its final value, we empirically show that it is possible to significantly reduce the number of learning steps. When used in conjunction with a varying learning rate, we empirically show that it outperforms original DQN on several experiments. We relate this phenomenon with the instabilities of neural networks when they are used in an approximate Dynamic Programming setting. We also describe the possibility to fall within a local optimum during the learning process, thus connecting our discussion with the exploration/exploitation dilemma. [less ▲]

The bottlenose dolphin (Tursiops truncatus) is an abundant top predator found in nearshore waters of South Florida including heavily developed and remote coastal waters. The objective of this study was to quantify total mercury (T-Hg) and persistent organic pollutant (POPs: NDL-PCBs, PBDEs, DDT, HCH, HCB, PCDD/Fs and DL-PCBs) levels in bottlenose dolphins found off the highly populated island of Key West (n = 27) and from the undeveloped Florida Coastal Everglades (FCE; n = 20). T-Hg and POPs were analyzed in skin and blubber tissues, respectively, using a Direct Mercury analyzer (for T-Hg), GC-ECD (POPs) and GC-HRMS (DLCs). The 7 ICES PCBs were the main compounds found in bottlenose dolphins from Key West (8229 ng.g-1 lipids) and the FCE (2289 ng.g-1 lipids), while the concentrations of PCDD/Fs remained low (Key West: 104 pg.g-1 lipids, FCE: 102 pg.g-1 lipids). POP concentrations were higher in individuals from Key West compared to those from the FCE. However, POP concentrations in Key West dolphins were lower than those from other locations in Florida and around the world. Unlike organic pollutants, T-Hg concentrations were significantly higher in FCE dolphins (Key West: 2941 ng.g-1 dw versus, FCE: 9314 ng.g-1 dw), with the highest concentrations reported from the southeastern US. PCB concentrations remained under previously suggested threshold for adverse health effects (including immunosuppression) in marine mammals of 17 000 ng/kg lipid. To conclude, sources of T-Hg and POPs differed between Key West and the FCE as reflected by their concentrations in skin and blubber of free-ranging bottlenose dolphins highlighting their role as sentinels of their environment.

In this paper, we model the severity distribution of operational losses data, condi- tional on some covariates. Indeed, previous studies [Chernobai et al., 2011, Cope et al., 2012, Chavez-Demoulin et al., 2014a] suggest that this distribution might be in uenced by macroeconomic and rm-speci c factors. We introduce a conditional Generalized Pareto model, where the shape parameter is an unknown function of a linear combina- tion of the covariates. More precisely, we rely on a single-index assumption to perform a dimension reduction that enables to use univariate nonparametric techniques. Hence, we su er neither from too strong parametric assumption nor from the curse of dimen- sionality. Then, we develop an iterative approach to estimate this model, based on the maximisation of a semiparametric likelihood function. Finally, we apply this method- ology on a novel database provided by the bank UniCredit. We use rm-speci c factors to estimate the conditional shape parameter of the severity distribution. Our analysis suggests that the leverage ratio of the company, the proportion of the revenue coming from fees as well as the risk category have an important impact on the tail thickness of this distribution and thus on the probability of su ering from large operational losses.

For more than 25 years now, traceroute has demonstrated its supremacy for network-path measurement, becoming the most widely used Internet path diagnosis tool today. A major limitation of traceroute when the destination is not controllable by the user is its inability to measure reverse paths, i.e., the path from a destination back to the source. Proposed techniques to address this issue rely on IP address spoofing, which might lead to security concerns. In this paper we introduce and evaluate DisNETPerf, a new tool for locating probes that are the closest to a distant server. Those probes are then used to collect data from the server point-of-view to the service user for path performance monitoring and troubleshooting purposes. We propose two techniques for probe location, and demonstrate that the reverse path can be measured with very high accuracy in certain scenarios. [less ▲]

Pour appuyer les efforts de conservation de la biodiversité, des processus de transfert de gestion (TG) des ressources naturelles aux communautés locales de base ont été promus à Madagascar depuis 1996 avec un important financement étranger. Ce p’rocessus était censé stimuler une forte responsabilisation des acteurs en plaçant la prise de décisions dans la sphère locale, ce qui améliorerait l’efficacité. Le transfert de fonds et de capacité ainsi que l’appui des partenaires sont également requis pour rendre la décentralisation effective. Pourtant, un désintérêt et une déresponsabilisation croissants quant à la gestion des ressources par les populations locales ont été souvent constatés et le taux de déforestation est resté élevé. C’est le cas de la zone forestière de Mariarano où nous avons eu l’occasion d’observer la mise en œuvre d’un TG. A travers les perceptions des acteurs clés dans le TG : la communauté locale et l’administration forestière, ce travail consiste à dévoiler les enjeux du processus participatif, les impacts de la dépendance à l’aide, les stratégies de contournement des règles par la population locale et l’évolution des rapports entre l’administration et ses partenaires dans le cadre de l’Etat local. A travers des actions déterminées par des prescriptions légales et des délais, les agents d’appuis activent le processus, négligent les clivages au sein de la population locale et cadrent les décisions résultants des négociations vers l’objectif de conservation. Cette procédure fait naître un sentiment d’imposition et aggrave l’illégitimité des normes promues. Par ailleurs, la population locale adopte un comportement opportuniste. Leur participation au processus fonctionne plus comme un mode de contrôle et d’accès aux ressources qu’un mode de préservation de celles-ci. Pour la réalisation des tâches attribuées à la population locale et des activités alternatives des usages, dont l’accès est désormais réglementé, l’appui des partenaires est nécessaire vu leurs faibles capacités financières et techniques. Toutefois, les appuis restent ponctuels et limités selon la priorité et la disponibilité budgétaire des bailleurs de fonds. La loi n’engage pas non plus les partenaires pour faire l’accompagnement sur le moyen terme, bien que ceci soit important pour provoquer des changements. Ceux qui n’ont pas ressenti les avantages concrets sont allés vers des pratiques illégales. Clandestinité et dissimulation sont les stratégies adoptées pour faire valoir leurs droits. Une amplification de la complicité au sein de la communauté gestionnaire est constatée pour contourner les règles. Quant au rapport de l’administration avec ses partenaires, il s’est détérioré. Dans un contexte marqué par la dépendance financière de l’Etat envers les bailleurs de fonds, l’administration est limitée dans ses fonctions et travaille comme consultant de ces derniers. Aux yeux des paysans, l’administration apparaît comme étant inapte à honorer ses engagements, ce qui nuit à sa crédibilité. Ainsi, elle rencontre des difficultés pour obtenir la confiance et la coopération de la population. Or celle-ci constitue le fondement de la gestion participative. La persistance des activités de déforestation résulte donc de l’illégitimité des normes résultantes du processus participatif, du recours des acteurs aux pratiques informelles et enfin de la paralysie de l’administration.

Rationale: Juvenile myoclonic epilepsies (JME) are one of the most common forms of genetic generalized epilepsy. Genetic studies have shown that heterozygous mutations in EFHC1/Myoclonin1 are responsible for 3-22% of JME cases worldwide. The Myoclonin1 protein contains three DM10 domains of unknown function and an EF-hand domain. We have previously demonstrated that Myoclonin1 is a microtubule-associated protein involved in cell division and radial migration during neocortex development. In cells, this protein co-localized with specific structures rich in microtubules (MTs) such as the centrosome, the poles of the mitotic spindle or the motile cilia but not with cytoplasmic MTs. This suggests post-translational modifications (PTM) of MTs may be important for the interaction between Myoclonin1 and MTs Methods: We co-expressed the different enzymes catalyzing PTM of MTs with Myoclonin1 in U2OS cell line, and then performed immunocytochemistry and western blot analysis. We next performed pulldown and luciferase complementation assays to test protein interaction Results: With one of these enzymes, we observed a strong increase in PTM in the presence of Myoclonin- 1.Interestingly, the effect is observed even when a DM10 domain alone is co-expressed with the enzyme, suggesting for the first time a role for this domain. This suggests that Myoclonin1 may interact with and modulate the activity of this enzyme. By using luciferase complementation assay and pull down experiments, we could demonstrate that both proteins interact. Conclusions: Our data suggest Myoclonin-1 modulates specific PTM of MTs. This is of prime importance for microtubule dynamic and notably for neuroblast precursor migration during neocortex development. This could be the mechanism that explains why pathological forms of myoclonin-1 may affect brain development. [less ▲]

Les nouvelles techniques LiDAR (Light Detection and Ranging) et photogrammétriques permettent d’acquérir rapidement un volume important de données 3D. Le terme LiDAR désigne tout instrument de mesure (terrestre, aéroporté) basé sur l’analyse des propriétés d’un faisceau renvoyé vers un émetteur (Poux et al. 2014). Conscient de l’énorme potentiel de ces techniques, l’Unité de Géomatique de l’Université de Liège a réalisé la numérisation de la Cathédrale Saint‐Paul de Liège. Ce projet a été initié via une collaboration avec le Matthieu Piavaux (FUNDP) et financée par le FNRS. Au‐delà des aspects de conservation et d’analyse du bâti, cette numérisation nous a permis de mettre en lumière les principes et limitations de la technique même d’acquisition de données 3D via LiDAR ainsi que ses limitations tant matérielles (sur terrain) que logicielles (traitement des données). Le jeu de donnée obtenu de la numérisation sert également de base fondamentale à un ensemble de projets de recherches (notamment via la réalisation de thèses de doctorats) visant à la segmentation automatique de nuages de points, de reconstruction d’objets tridimensionnelles, d’analyse de qualité d’ajustements. Par la suite, nous détaillons la méthodologie utilisée pour l’acquisition du nuage de points 3D ainsi que les différents principes de calage de nuages. Le chapitre suivant sera consacré à la présentation de résultats ainsi que de premiers développements en termes de segmentation automatique. Finalement, nous dresserons quelques perspectives de représentations. [less ▲]

Quantifying the biomass and carbon stocks contained in tropical forests has become an international priority for the implementation of the REDD+ mechanism. Forest biomass is estimated through three successive levels: the tree, the stand and the region level. This study reviews the state of the art on the estimation of biomass and carbon stocks contained in tropical African forests. This review highlights that only few allometric equations, equations used for estimating biomass of the tree from non-destructive measurements (diameter, height), have been established for tropical African forests. At the stand level, this synthesis highlights the spatial and temporal variations in biomass between forests types in Central and Eastern Africa. While biomass recovery after disturbance (logging for instance) is rather quick, there is still a lot of uncertainity on the spatial variation in biomass, and there is no consensus on a regional biomass map. The quality of biomass mapping in tropical Africa stronly depends on the various sensors used (optical, RADAR or LIDAR), the allometric equation used to convert forest inventory data and sampling design. Based on the lack of precision of available allometric equations and forest inventory data a large spatial scale, many uncertainties persist on estimating the biomass and carbon stocks contained in the African tropical forests. It is important to develop reference sites (both allometry and forest inventory) to provide accurate biomass estimates for an effective implementation of the REDD+. [less ▲]

Dans ce cas, il est naturel d'étudier la distribution des exposants de Hölder: cette information est donnée par le spectre de singularités de la fonction. En général, ce spectre est assez difficile à calculer et on utilise des méthodes pour l'estimer.

Hydrogeophysics has become a major field of research in the past two decades and time-lapse electrical resistivity tomography (ERT) is one of the most popular techniques to monitor passive and active processes in subsurface reservoirs. Time-lapse inversion schemes have been developed to refine inversion results; but, in contrast with static inversion, they mostly still rely on the spatial regularization procedure based on the standard smoothness constraint. In this contribution, we propose to apply a variogram-based regularization operator in the time-lapse ERT inverse problem, using the model difference covariance matrix to replace the standard smoothing operator. The variogram of resistivity variations can be computed through independent borehole data, such as electromagnetic logs or hydrogeological monitoring, which is often available during monitoring experiments. We first illustrate the method for surface ERT with a synthetic case and compare the results with the standard smoothness constraint solution. This example shows that the variogram-based constraint images better the assumed anomaly both in terms of shape and amplitude. The improvement is largely higher than the one obtained with more classical anisotropic smoothness constraint. This synthetic example also shows that an error made in the range of the variogram has a limited impact on the resulting image, which still remains better than the smoothness constraint result. Anomalies located in various part of the tomograms were tested. Although more crucial in low-sensitivity zones, improvements are observed everywhere in the tomograms. The method is then applied to cross-borehole ERT field data from a heat tracing experiment, where the comparison with direct temperature measurements shows a strong improvement of the breakthrough curves retrieved from ERT. Using the variogram-based regularization, it is possible to reduce the smoothing of resistivity variations in low sensitivity zones and therefore to avoid overestimation of temperatures. The proposed method could be extended to the time dimension which would allow the use of variogram-based constraints in 4D inversion schemes. [less ▲]

This paper proposes a network proximity service based on the neighborhood models used in recommender systems. Unlike previous approaches, our service infers network proximity without trying to recover the latency between network nodes. By asking each node to probe a number of landmark nodes which can be servers at Google, Yahoo and Facebook, etc., a simple proximity measure is computed and allows the direct ranking and rating of network nodes by their proximity to a target node. The service is thus lightweight and can be easily deployed in e.g. P2P and CDN applications. Simulations on existing datasets and experiments with a deployment over PlanetLab showed that our service achieves an accurate proximity inference that is comparable to state-of-the-art latency prediction approaches, while being much simpler.

La détermination des propriétés hydrauliques du sol est une préoccupation majeure dans différents domaines d’études. Bien que les sols caillouteux soient répandus dans le monde entier, la plupart des études ne caractérisent que la fraction fine des sols, si bien que la littérature décrivant l’impact des cailloux sur les propriétés hydrauliques du sol est encore rare. Certains modèles ayant pour but de caractériser ces propriétés hydrauliques reposent sur la même hypothèse simplificatrice, qui stipule que le seul effet des cailloux est de diminuer le volume disponible pour l’écoulement de l’eau. L’objectif de cette étude est de vérifier cette hypothèse et, le cas échéant, d’identifier les facteurs déterminant ou non son respect. L’effet des cailloux sur la conductivité hydraulique à saturation effective du sol a été testé au moyen d’expériences de laboratoire et d’expériences numériques, impliquant différentes quantités et types de fragments grossiers. Nos résultats montrent que plusieurs facteurs supplémentaires, non considérés par ces modèles, peuvent affecter significativement la conductivité hydraulique à saturation. D’une part, la forme et la taille des inclusions altèrent de manière substantielle la conductivité hydraulique. D’autre part, la présence de cailloux peut contrer -voire dominer- les effets liés à la réduction du volume disponible pour l’écoulement en conditions saturantes. Nous attribuons cela à la création de macropores à l’interface entre la terre fine et les cailloux. [less ▲]

L’activisme associatif dans le domaine de la déficience intellectuelle a connu des évolutions significatives depuis quelques décennies. Suivant les principes fondateurs de la Convention des Nations Unies relative aux droits des personnes handicapées (2006), les associations de personnes concernées revendiquent leur légitimité à s’impliquer activement dans la gouvernance des questions qui les concernent.

The direct measurement of loads with force balance can become challenging when the forces are small or when the body is moving. An alternative is the use of Particle Image Velocimetry (PIV) velocity fields to indirectly obtain the aerodynamic coefficients. This can be done by the use of control volume approaches which lead to the integration of velocities, and other fields deriving from them, on a contour surrounding the studied body and its supporting surface. This work exposes and discusses results obtained with two different methods: the direct use of the integral formulation of the Navier-Stokes equations and the so-called Noca's method. The latter is a reformulation of the integral Navier-Stokes equations in order to get rid of the pressure. Results obtained using the two methods are compared and the influence of different parameters is discussed. The methods are applied to PIV data obtained from water channel testing for the flow around a 16:1 plate. Two cases are considered: a static plate at high angle of attack and a large amplitude imposed pitching motion. Two-dimensional PIV velocity fields are used to compute the aerodynamic forces. Direct measurements of dynamic loads are also carried out in order to assess the quality of the indirectly calculated coefficients. [less ▲]

Activity recommendation systems aims at providing relevant information depending on targeted users' groups. For instance in a city, it makes sense to differentiate local residents from tourists. This research investigates to what extent the anonymized data collected from social networks can be used as a basis for making activity recommendations associated with local residents versus tourists when visiting a public place, such as a museum or gallery. Using rules based on the spatial, temporal and semantics of visited places, we are able to infer if a user is likely to be local or a tourist, based on anonymous sample Foursquare data and place-based semantics retrieved using Google Places API. Using semantics of visited places, it becomes possible to infer additional information about a user based on their movements over space and time. Depending on the kind and frequency of visited places, inferences about the aim of a visit to a location are possible. This analysis could provide information to users in the form of recommendations based on their movements while travelling around an area. This study has been performed using Foursquare check-ins for visitors to the Art Institute of Chicago between March 2010 and January 2011. [less ▲]

La diversité des sources relatives aux horoi – limites, frontières, bornes – dans le monde grec antique est sans doute révélatrice de l'importance de la délimitation et du bornage de la terre aux yeux des anciens Grecs. C'est la retranscription de cet enjeu multiforme – tant symbolique que matériel, politique qu'économique – dans le champ du polythéisme qui fera l'objet de cette présentation. Si l'on se borne aux puissances divines explicitement invoquées comme garantes de ces horoi, on constate qu'au sein d'un ensemble où l'on rencontre Apollon, Athéna, Héra, émerge incontestablement la figure du Zeus Horios. La mise en contexte et en série des données relatives au culte de ce dernier, ainsi que l'examen des logiques théologiques qui les soutiennent et les procédés rituels qui les accompagnent, formeront par conséquent le cœur de cette étude. Au-delà des possibilités d'expérimentation sur le fonctionnement du polythéisme hellénique qu'elle offre, cette étude de cas permettra, on l'espère, d'éclairer la manière grecque d'investir symboliquement la terre, en l'occurrence de justifier sur le plan religieux les délimitations appliquées à celle-ci.

In microfluidics flow focusing is widely used to produce water-in-oil droplets in microchannels at high frequency. Nevertheless, the scaling laws associated to droplet length, speed and frequency could not be identified yet, owing to the large number of parameters involved (incl. complex geometry). We here present an experimental study of droplet formation in a microfluidic cross-junction with a minimum number of geometrical parameters. We mostly focus on the dripping regime. The formation sequence is decomposed in two steps, inflation and squeezing, that vary differently according to both water and oil flow rates. These variations reveal several insights about the fluid flows in both phases. From there we infer the scaling law that relates droplet volume and frequency to the Capillary number associated to each inlet flow rate. This law involves a minimum of fitting parameters. We finally discuss the influence of inlet control (flow rate vs. pressure) and surfactants on the formation dynamics. [less ▲]

Coptic, as it comes down to us in written texts, is massively influenced by Greek in the domain of lexicon. The Leipzig-Berlin Dictionary and Database of Greek Loanwords in Coptic project has already recorded c. 5000 loan word types and c. 60.000 loan word tokens. On this basis, linguists, philologists, and historians often make assumptions about the nature and extent of bilingualism. Some linguists have even proposed that Coptic is a case of ‘code-mixing’ of Egyptian and Greek, which assumes extensive bilingualism among Egyptians in Late Antiquity. In this paper, we tackle this question from another angle, by determining the extent to which Greek influenced Coptic in terms of its *basic vocabulary*. It may be that we can learn more about bilingualism in Late Antique Egypt this way, since overall lexical borrowing need not correlate with lexical borrowing in the domain of basic vocabulary. As a (significant) side effect of this study, we can also describe the rate of replacement of basic vocabulary in Egyptian-Coptic across its 4000 years of attestation, as well as the semantic domains and periods in which lexical replacement was faster or slower.

Objectif Les tests isocinétiques contribuent régulièrement à l'évaluation de la performance musculaire et en sont considérés comme un gold standard [1]. Les tests de fatigabilité peuvent s'avérer complémentaires des épreuves courtes de force notamment pour évaluer un athlète sollicitant particulièrement la filière anaérobie lactique ou dans des contextes pathologiques spécifiques [2]. Bien que Bosquet et al. [3] aient démontré la reproductibilité d'un protocole de fatigabilité pour le genou, à notre connaissance, aucune étude, ayant pour objectif d'être exhaustive dans son analyse, n'a été menée sur la reproductibilité des paramètres mesurés (meilleure répétition, cumuls total et partiels) et index de fatigue (quotient des n dernières répétitions par les x premières, du cumul des répétitions par la meilleure,…). Ces index et paramètres mesurés sont néanmoins proposés directement par les dynamomètres, sans en connaître systématiquement la méthode de calcul, et/ou utilisés en clinique et dans la littérature pour caractériser la fatigabilité musculaire du genou [4]. Sont-ils cependant suffisamment reproductibles pour que leur utilisation soit scientifiquement validée? Matériel & méthode Dix-huit sujets, modérément actifs, ont réalisé trente extensions-flexions maximales du genou à trois occasions, avec sept à dix jours de repos entre chaque session. Le moment de force maximum (MFM) et le travail maximal (Wmax) de chaque répétition ont été enregistrés pour compiler onze paramètres mesurés et construire quarante-quatre index. La reproductibilité de chaque paramètre et index a été évaluée via leur ICC (2,1), SEM et MD respectifs. Résultats Les valeurs d'ICC des paramètres mesurés pour les extenseurs du genou sont quasi-systématiquement supérieures à 0.8 tandis que celles pour les fléchisseurs oscillent entre 0.7 et 0.8. Les valeurs d'ICC pour les "index de fatigue" construits sont inférieures à 0.7 et 0.5 respectivement pour les extenseurs et fléchisseurs. Aucune différence notable n'est observée entre la reproductibilité du MFM et celle du Wmax (que ce soit pour les extenseurs ou les fléchisseurs ou pour les paramètres mesurés et les "index de fatigue"). Discussion Au vu des valeurs obtenues sur notre population, il apparait qu'aucun index de fatigue calculé ne semble suffisamment reproductible pour une utilisation clinique ou scientifique! Seuls les paramètres mesurés tels que la meilleure répétition, le cumul total ou partiel présentent une reproductibilité qui peut être qualifiée de (très) haute voire excellente et sont donc utilisables en clinique ou en recherche pour caractériser la fatigabilité musculaire du genou.

French-speaking Belgian opinion on Nazi Germany can be seen through multiple lenses and very different focuses. We will analyze the main Catholic intellectual periodicals published between 1933 and 1939, explaining our selection by a description of the weight of political Catholicism in the interbellum (("La Revue Générale", "La Revue Belge", "La Revue Catholique des Idées et des Faits", "La Cité Chrétienne", "La Terre Wallonne", "La Revue de l'Ordre Corporatif"). After reading six years of rather copious and often verbose articles, can we summarize and better define themes in their approach of Nazism? Are the articles studies in depth or are they merely floating on the surface, in spite of the amount of printed space occupied by them? Was Nazism seen as a new phenomenon, a form of New Order, or simply as a mere link in a continuous German history? Why is Hitler’s regime seen as perpetuating the Prussian State (and “Prussian” state of mind) or frowned upon as a conquering mystical or religious force applied to political expansion such as Islam had been? Which place is given to racist and völkisch views, to their contradiction with Christian ideals, to antisemitism? To which extent was Nazism rational or irrational, using empiricism or applying a spirit of system? Were the writers of 1933-1939 taking into account the social and economic reforms, the “progresses” accomplished, were they paying more than lip-service to the communitarian spirit of Volksgemeinschaft?

Qu’elle soit appréhendée comme un symptôme ou un remède, la médiation apparaît dans un contexte où les liens sociaux se recomposent, où les institutions traditionnelles (état, église, école, justice, etc.) sont questionnées et où la prise en compte des singularités devient la norme. Depuis près de quarante ans, de multiples fonctions et dispositifs dits « de médiation » prolifèrent dans le but affirmé de créer ou renouer des liens entre les individus. Pour ce faire, les processus communicationnels sont privilégiés, alternativement ou parallèlement à une approche autoritaire. « La » médiation, pratiquée dans différents champs (notre entrée empirique étant celle de la médiation scolaire), fait l’objet de nombreux discours (politiques, managériaux, professionnels, scientifiques, etc.) mais sa définition et sa mise en œuvre entraînent plusieurs difficultés. Son caractère indéfini ou multidéfini, flexible et malléable ouvre certes à une utilisation contextualisée, adaptée aux situations et aux individus. Mais ceci ouvre également à des interprétations et à des usages hétérogènes, parfois paradoxaux, et à des « débordements » pouvant menacer la légitimité des médiateurs et des dispositifs de médiation. Notre contribution vise par conséquent à rendre compte de l’ambiguïté constitutive des discours, des dispositifs et des pratiques de médiation scolaire, ceci afin d’en éclairer les ressources et les limites.

Background: The common sense model of self-regulation (CSM) provides a framework for understanding the connection between emotions, thoughts and behaviors in people experiencing illness. However, most of model in health psychology, including the CSM, were initially addressed to adult patients. Objective: This study examines the traditional conceptualization of the CSM where coping act as a mediator of the relation between illness perception and emotional distress in a pediatric population with chronic disease, namely Cystic Fibrosis (CF). Method: Using a cross-sectional design, 38 children with CF aged between 8 and 12 years participated in the study. All children were asked to complete: the State-Trait Anxiety Inventory for Children (STAIC), the Children’s Depression Inventory (CDI), the Kidcope and the Children’s Illness Perception Questionnaire (CIPQ). A composite score labelled “emotional distress” including scores of anxiety and depressive symptoms were created. Results: Illness perception predicted emotional distress (Timeline: β = .43; t = 2.835; p = .007; Consequences: β = .50; t = 3.429; p = .002; Control: β = .18; t = 1.088; p = .284). As regard with coping strategies, only emotional outburst and distraction predicted emotional distress (emotional outburst: β = .48; t = 3.241; p = .003; distraction: β = .32; t = 2.038; p = .049). However, there were no relation of illness perception subscales with emotional outburst and distraction. Therefore, the mediational role of coping strategies between illness perception and emotional distress could not be tested. Conclusion: Findings did not confirm the original conceptualization of coping as a mediator suggesting that the CSM needs to be adapted when applied with a pediatric population. Even though young children are able to think before acting (i.e. Piaget’s work), future research should explore the possibility that cognitions and actions exist at the same level and can independently impact adjustment outcomes.

Introduction: Graft-versus-host disease (GVHD) has remained a major complication of allogeneic hematopoietic stem cell transplantation (HSCT) for the last decades. Following unmanipulated peripheral-blood stem cell transplantation, 60% of the patients experience chronic GVHD while approximately 15% of them develop a sclerodermic form of chronic GVHD characterized by multiple organ fibrosis and loss of skin elasticity. Regulatory T cells (Tregs) play a pivotal protective role in the pathogenesis of chronic GVHD by inhibiting alloreactive conventional T cells (Tconvs). Several studies have shown that hypomethylating agents such as azacytidine (Aza) can demethylate the master transcription factor of Treg (Forkhead box protein 3 factor, FoxP3), thus promoting Treg differentiation from Tconvs. This work investigates the impact of Aza in a classical murine model of sclerodermic chronic GVHD (B10.D2  BALB/cJ). Methods: In vitro analyses have been performed to determine the impact of Aza on collagen production. NIH-3T3 fibroblastic cells were plated and stimulated with 50 ng of PDGF or 10 ng of TGF-beta. Cells were then cultured with various concentrations of Aza for 48 hours. After culture, cells were stained with Sirius Red before quantification of collagen amount by absorbance at 490 nm. For in vivo experiments, lethally irradiated (7 Gy) BALB/cJ recipient mice were injected with 107 bone marrow cells + 7.107splenocytes from B10.D2 donor mice to induce scl-cGVHD. Recipients were injected with either 0,5 or 2 mg/kg of Aza every 48 hours from day 10 to 30 following transplantation. GVHD was scored using a five criteria scale (weight loss, activity, fibrosis, hair loss and mice posture; 0-1-2 points/criteria). Mice were sacrificed at a score of 8/10 (or > 20% weight loss) or at day 52 after transplantation (end of experiment). Results: Concerning in vitro analyses, results suggest a decreased production of collagen at higher concentration of Aza with both stimulations (seen by a gradual diminution of absorbance). For in vivo experiments, mice treated with Aza 0.5 mg/kg (n = 14) or 2 mg/kg (n = 25) had significant lower clinical scores of GVHD compared to control ones (n = 23) after treatment. FACS analysis showed a higher proportion of Treg among CD4+ T cells in the blood of Aza 2 mg/kg mice than in control mice at day 35 following transplantation (P = 0.047), as well as a higher percentage of Tregs expressing the KI67 proliferative marker on the same time point (P = 0.0005). Finally, analyses of the cellular blood components with Cell-dyn demonstrated that Aza 2 mg/kg treated mice were significantly lymphopenic as compared to control mice at day 35 after transplantation (P = 0.05). Conclusion : Aza prevented sclerodermic GVHD in this classical murine model of chronic GVHD. [less ▲]

The speech aims at delineating a proper ethical and legal response to the ‘dual-use dilemma’ of nuclear science and technologies. After assessing the different models of governance proposed so far in nuclear field for addressing the ‘dual-use’ feature of nuclear technologies, and based on precautionary, proactionary or cost/benefit approaches, it suggests the adoption of a framework based on the notion of ‘responsible stewardship’. This model entails: (a) a constant analysis of nuclear technology, both on the side of risks and of benefits, through the involvement and cooperation of all the stakeholders in the field (the involvement of both ‘top down’ and ‘bottom up’ actors, i.e. governments and scientific community); (b) the adoption of policies through ‘hard law’ and ‘soft law’ sources, which should be periodically revised, and based on the proportionality principle and the reasonableness one (with a balance among rights and freedom, from a constitutional viewpoint); (c) an ongoing communication, dialogue and interaction between actors in the nuclear area. A specific attention is devoted to the balance between the freedom to research and the security needs. Then, the concrete ways for applying such model are explained, in particular with regards to the issue of control of materials, education of people, and control of information. Finally, the historical steps in the governance of nuclear technologies and the positions of different religions addressing the issue have been explored, in order to provide some examples of the suggested approach.

Molecular biology techniques are widely used in mycology. First of all they are used for confirmation of difficult or uncertain identifications. In this case PCR followed by ITS sequencing is generally used. For diagnostic purposes, PCR is mostly applied for the detection of invasive infections such as pneumocystosis, candidosis or aspergillosis. However these techniques (Candida and Aspergillus detection) are still not included in the recommandations given by EORTC by lack of standardisation. However, the development of new commercially available techniques, will probably change the diagnostic algorithm. New commercial PCR kits applied to the detection of dermatophytes are also recently available to the laboratories and they will be a good complement to culture-based diagnostic methods. [less ▲]

Certains étudiants peuvent répondre au hasard ou être inattentifs dans une situation de testing. Plusieurs approches ont déjà été développées pour détecter ce type de réponse (Zickar et Drasgow, 1996). Parmi celles-ci, l’utilisation d’indices de détection de patrons de réponses inappropriés (person-fit indices) est l’approche qui est la plus étudiée et qui semble la plus prometteuse (Karabatsos, 2003; Meijer et Sijtsma, 2001). Dans le cadre de cette étude, nous nous concentrerons sur trois indices de détection populaires qui présentent des caractéristiques permettant d’en faciliter l’interprétation : lz (Drasgow, Levine et Williams, 1985), ZU (Wright et Masters, 1982) et ZW (Wright et Masters, 1982). Toutefois, il s’est avéré qu’ils sont tous fortement affectés par le fait que l’habileté d’un étudiant est estimée plutôt que réelle (Li et Olejnik, 1997; Molenaar et Hoijtink, 1990). Voilà pourquoi Snijders (2001) a proposé une version corrigée de l’indice lz (nommée lz*) qui prend en considération ce problème important. Nous avons déjà appliqué la correction de Snijders aux indices U et W en créant les indices ZU* et ZW* (Magis, Béland et Raîche, 2014). L’objectif de cette étude sera d’examiner le comportement des indices corrigés lz*, ZU* et ZW* et de leur version standardisée. Pour ce faire, nous effectuerons trois études différentes : une analyse descriptive des scores des indices, une analyse des erreurs de type I et une analyse de leur puissance de détection. Les analyses ont démontré que ce sont les indices corrigés lz* et ZW* qui sont les plus intéressants à utiliser puisque leurs scores suivent approximativement la loi N(0,1) et puisqu’ils permettent de bien détecter les réponses qui s’apparentent au hasard et à l’inattention.

BACKGROUND: Natural T regulatory cells (Treg) are challenging to expand ex vivo, and this has severely hindered in vivo evaluation of their therapeutic potential. 5-Azacytidine (5-azaC) and Rapamycin (RAPA) are immunosuppressive drugs that promote selectively the expansion of CD4+CD25highFoxp3+ regulatory T cells OBJECTIVE: We investigated whether 5-azaC and RAPA could be used together to promote the ex vivo expansion of Tregs purified from adult human peripheral blood. METHODS: CD4+CD25+ and CD4+CD25- T cells were isolated from PBMC of normal controls using Miltenyi beads and FACS ARIA sorting. These cells subsets were cultured in the presence of anti-CD3/CD28 antibodies and 200 IU/ml of IL2 for 2 weeks. RAPA (100nM) and 5-azaC (1µM) were added to half of the cultures. We monitored cell expansion and after harvest, the cell phenotype, gene expression, T suppression activity and Annexin V binding were determined and compared to values obtained with control cell culture and with freshly-separated CD4+CD25+ and CD4+CD25- T cells. Also we tested the absolute number of Treg in the several culture conditions during the time of expansion. RESULTS: We found that 5-azaC helped maintain FOXP3 expression during the expansion process probably by promoting the conversion of T conventional (Tconv) in Treg, instead Rapa induces selectively apoptosis in Tconv cells and expansion in Treg. The addition of 5-azaC to RAPA treated cultures improved gene expression of FOXP3, CD25, STAT5 and TGF-B resulted in enhanced Treg expansion and suppressive activity. Also Rapa and 5-AzaC combination sustain Bcl-2 protein expression in Treg conferring resistance to apoptosis process. CONCLUSION: 5-azaC may have utility in ex vivo expansion of human Tregs, not as a single agent, but in combination with RAPA. These data may considerably accelerate the development of immunotherapeutic approaches for the treatment of autoimmune disease or posttransplant alloreactions by the adoptive transfer of nTreg cells.

Bien caractériser la phénologie des essences forestières dans un contexte climatique changeant est indispensable. Dans cette optique, confronter les différentes sources d’informations phénologiques (relevé de terrain, modélisation, capteurs de rayonnement, caméra phénologique, satellite, eddy covariance…) est une démarche essentielle. Les différences et la complémentarité de ces sources d’informations ont été mises en évidence en utilisant les données provenant d’une forêt mixte de l’Est de la Belgique, principalement composée de hêtres. Par ailleurs, ces informations ont été utilisées pour étudier l’influence de la phénologie des hêtres sur les échanges annuels de CO2 de ces derniers. [less ▲]

As the use of models is increasing within regulatory bodies, it is important to grasp both the empirical practices of producing and using them, and their political meaning. At stake here is the possibility of identifying the characteristics of a way of governing anticipations that would be based on models. In this paper, we engage in such an exploration by focusing on models developed to predict the potential risks of chemicals. These models, called “Quantitative Structure-Activities Relationship” (QSAR), are based on statistical correlations between a set of descriptors (e.g. chemical composition, crystalline structures…) and a set of physicochemical properties, including potential toxicity. They are developed using a limited number of substances that serve as reference points, so that the properties of other chemicals could later be predicted by the model, according to their proximities to the reference points. QSAR models have been promoted by regulatory agencies for over twenty years, but have been recently gaining momentum in Europe, in the wake of the REACH regulation. As the regulation on chemicals is becoming more constraining on private companies, usual experimental approaches raise many concerns (which are lengthy, costly and often requires animal testing). Based on the analysis of the relevant documentation, interviews with scientists and regulators, as well as the ethnographic observation of a recent research project attempting to developed QSAR models for nanomaterials, this paper provides the preliminary elements for describing the mode of governing anticipation that emerges from the use of such models. We contend that QSAR approaches offer empirical examples to identify a mode of governing anticipation based on flexibility, understood at the epistemic and political levels. [less ▲]

Lorsque le diagnostic de maladie d’Alzheimer est posé, les atteintes au niveau du cerveau et l’ampleur des difficultés dans la vie quotidienne ont atteint un seuil critique. Actuellement, les chercheurs et les cliniciens pensent que pour tenter de retarder l’apparition d’une démence, voire même l’empêcher, il faut agir bien avant que les premiers symptômes majeurs apparaissent. Le défi actuel est de trouver les meilleurs outils permettant de détecter le plus tôt possible les premiers signes de la maladie. Etant donné que des changements cognitifs peuvent être détectés très tôt, les neuropsychologues tentent d’identifier parmi les tests qui forment le bilan neuropsychologique ceux qui permettent de prédire au mieux le développement futur d’une maladie d’Alzheimer. Les recherches ont suggéré que les mesures ayant le meilleur pouvoir de prédiction semblent être celles de mémoire épisodique (qui est la capacité à se souvenir d’événements vécus dans un contexte bien précis) et les mesures de fluence verbale (qui est la capacité à citer un grand nombre de mots appartenant à une catégorie ou commençant par une lettre donnée). Le groupe Vieillissement et Mémoire, au sein du Centre de Recherches du Cyclotron (Université de Liège), poursuit actuellement deux lignes de recherche en lien avec la question de la détection précoce de la maladie d’Alzheimer : Premièrement, nous tentons de déterminer si nous pouvons encore mieux détecter les personnes à risque de développer une maladie d’Alzheimer en affinant les mesures de la mémoire. Le point de départ de cette recherche doit être une compréhension approfondie des mécanismes qui régissent le fonctionnement de la mémoire ainsi que de leurs bases cérébrales. Nos premiers résultats ont montré une perte précoce de la capacité à réactiver tous les détails d’un épisode vécu, associée à une déconnexion entre les régions d’un réseau cérébral incluant le cortex cingulaire postérieur et l’hippocampe. Deuxièmement, nous étudions les facteurs protecteurs qui permettent à certaines personnes de mieux résister que d’autres aux effets négatifs du vieillissement et de la pathologie cérébrale. Une étude non encore publiée menée auprès de personnes âgées sans trouble cognitif a montré que plus les personnes avaient étudié longtemps et avaient pratiqué une activité physique au cours de leur vie, meilleure était leur capacité à se souvenir des détails des événements vécus. Enfin, une approche idéale pour Identifier le plus tôt possible qui risque de développer des symptômes de déclin cognitif est l’approche multidisciplinaire. Plutôt que d’évaluer l’intérêt d’une mesure seule, nous proposons de tenir compte de manière combinée des différents éléments qui semblent contribuer à la détection précoce de la maladie d’Alzheimer : modifications neuropathologiques, mesures neuropsychologiques, mesures de la structure et du fonctionnement cérébral, habitudes de vie, changements physiologiques et modification du sommeil.

The course of “Introduction to Human Anatomy” is part of the curriculum delivered to the undergraduated students (Freshman year) at the Faculty of Medecine of the University of Liege. The course is taught in a blending learning mode combining traditional intructor-led and e-learning activities. The MCQ 2 test is one of the three components of the final written exam (which consists of 3 MCQ tests). This test requires students to recognize and identify the organ’s orientation in cross-sections represented in different spatial views. In our study, we tried to evaluate how the online training exercises provided by the instructors team for that particular ability was appreciated by students and if students benefited from this type of online activities to improve their examination results for MCQ 2 test. Further in our research, we asked student about their perceptions of coherence between the aims, methods and evaluation of our entire system. Then this perception has been compared with the overall score of the exam to look for the present of correlation elements. We observed that the MCQ 2 test results are significantly better for students who practiced the new online exercises and for students having seen the value of this activity. The perception of consistency or coherence between the objectives, methods and assessment is not correlated to the overall score of the student. As conclusion, we can declare that the new learning scenario proposed positively enriches the learning environment for students. It can be easily scaled up for important groups and accessed at any time by users. It focusses on specific objectives, is directly linked to the examination system of the course (MCQ 2) and also allows developing a competence expertise related to their future medical profession.

En février 2013, les Bibliothèques de l'Université de Liège ont mis en production la solution discovery Primo, hébergée en local. Le projet s’est étalé sur une dizaine de mois, offrant ainsi aux professionnels des Bibliothèques la possibilité de se familiariser avec le nouvel outil avant le lancement officiel. Moins d’un an plus tard, les Bibliothèques décidaient de passer au système de gestion de bibliothèque Alma, ce qui impliquait à nouveau le déploiement d’un Primo, cette fois-ci dans le cloud. En six mois, la migration vers Alma et le lancement de la nouvelle interface discovery étaient réalisés. Cette présentation balaye les moments clés des deux projets de déploiement Primo, en mettant l'accent sur la composante organisationnelle, la formation des équipes et la gestion du changement.

This study investigated the determinants of financial inclusion for small scale farmers by focusing on the access to formal and informal agricultural credits in the Southern Province of Rwanda. Data were collected from 310 farmers from Huye and Nyamagabe districts through an open-ended structured questionnaire and analysed using the binary logistic regression method. The major findings, on one hand, showed that among the requested and approved agricultural loans, 87.2% and 12.7% were from informal and formal financial institutions respectively. Among those who accessed agricultural credits, 59.7% were from Huye and 40.3% from Nyamagabe. On the other hand, it was revealed that the household characteristics and the community attributes are the most important determinants. Those household characteristics include household income and expenditure, Ubudehe socio-economic category of the household, off-farm employment and the size of the land owned by the household whereas community attributes involve residence area, transport and informal financial services availability. Regarding farmer characteristics, the education level was found to be the only factor affecting the smallholder farmers' access to agricultural credit. In light of the findings, it was recommended to conduct sensitization sessions focusing on the importance of agricultural credits for smallholder farmers especially in the areas with high level of poverty. In addition, there is need to work on alleviating the formal agricultural credits access barriers, and to conduct a study on the dynamics of informal and formal agricultural credits up take and usage by smallholder farmers to explore all dimensions of financial inclusion in the study area.

Aim Coding abstracts of communications of GPs during congress allows more efficient exchange of information through a specific indexing process. Coding with Core Content Classification in General Practice/Family Medicine (3CGP/FM), an association of ICPC and of a new tool called Q-Codes means identifying the main concepts the writer is willing to share in his/her contribution. This is called ‘text classification’ or ‘topic list building’ in computer sciences and ‘qualitative data analysis’ in cognitive sciences. The GP is dealing with issues concerning the patient and with issues concerning the management of the job. Symptoms, diagnosis and process are up to what we will call clinical activities. General management as well as ethical or quality related issues are up to what we will call non-clinical or managerial activities. Clinical activities will be identified in the abstracts by the use of the International Classification of Primary Care second edition, electronic, version 5 (ICPC-2 e ver5). Managerial activities will be identified in the abstracts by the use of the Q-Codes, version 2.1, 2015 which we are explaining now in detail. Method The European cross-lingual portal of health terminologies for indexing and searching Web resources (www.hetop.eu) is using the OWL 2 Web Ontology Language, relying for instance to Bioportal and connected to the world of the Internet of data. We have developed the terminological content of 183 items called Q-codes using a graphic Interface, filling the knowledge base with relevant information about the concept studied, linking them to professional terminologies like MeSH, or to lay ones like Babelnet and DBpedia, if any, and relying them to top bibliographic free full text citations of the domain. Results 183 Q-Codes have been designed and 177 extensive terminological records are available online, for now for beta testers. The whole process is described on http://docpatient.net/3CGP. The ongoing version of the Q-codes is available here in 6 languages http://docpatient.net/3CGP/Q-Codes_ver_2_2.pdf The poster present a general overview of the terminological development. [less ▲]
