Background: Rodents are recognized as hosts for at least 60 zoonotic diseases and may represent a serious threat for human health. In the context of global environmental changes and increasing mobility of humans and animals, contacts between pathogens and potential animal hosts and vectors are modified, amplifying the risk of disease emergence. An accurate identification of each rodent at a specific level is needed to understand their implications in the transmission of diseases. Among Muridae, the Rattini tribe encompasses 167 species inhabiting South East Asia, a hotspot of both biodiversity and, emerging and re-emerging diseases. The region faces growing economical development that affects habitats, biodiversity and health. Rat species have been demonstrated as main hosts of pathogens but are still difficult to recognize at a specific level using morphological criteria. DNA-barcoding methods appear as the only tool for accurate rat species identifications but their usefulness is hampered by the need of reliable identifications of reference specimens. To provide a rigorous systematic framework for epidemiological surveys, we used DNA data to explore the limits of the current taxonomy of the Rattini tribe. Results: As morphological characters are often misleading, we decided to use the DNA sequence information itself as the primary information source to establish group membership and estimate putative species boundaries. We sequenced two mitochondrial and one nuclear genes from 122 rat samples to perform phylogenetic reconstructions and applied the method developed by Pons and colleagues (2006) that determines with no a prior expectations, the locations of ancestral nodes defining putative species. To give an appropriate name to each cluster recognized as a valid species, we reviewed information from the literature and obtained sequences from a museum holotype specimen following all the ancient DNA criteria. One of the most striking results is that at least 6 putative species including a new cryptic one could exist among the Rattus rattus species group. Conclusions: Using a suitable methodology, this study succeeds in refining the taxonomy of one of the most difficult groups of mammals and lays the foundations to better investigate rodent-born diseases in South East Asia. Recognition of a new cryptic Rattus species in Southeast Asia could have serious implications for human health since each species is expected to have its own ecological traits and to carry its own set of diseases. To finish, first results based on independent nuclear DNA data (microsatellite loci) will be briefly exposed to demonstrate that defining species is not an easy task. [less ▲]

The Hybrid Finite Element Mixing Cell (HFEMC) method is a flexible modelling technique particularly suited to mining context (Brouyère et al., 2009). The principle of this method is to subdivide the modelled zone into several subdomains and to select a specific equation, ranging from the simple linear reservoir equation to the groundwater flow in porous media equation, to model groundwater flow in each subdomain. The model can be run in transient conditions, which makes it a useful tool for managing mine closure post-issues such as groundwater rebound and water inrushes. An application of the HFEMC method to an abandoned underground coal mine near the city of Liège (Belgium) is presented. The case study zone has been discretized taking advantage of the flexibility of the method. Then, the model has been calibrated in both steady-state and transient flow regimes based on hydraulic head and water discharge rate observations. Finally, the calibrated model has been used to run several scenarios in order to assess the impacts of possible future phenomena on the hydraulic heads and the water discharge rates. Among others, the simulation of a strong rainfall event shows a quick and strong increase in hydraulic heads in some exploited zones coupled with a strong increase in associated water discharge rates. This could lead to stability problems in the hill slopes near the exploited zones. This kind of predictions can greatly help managing and predicting mine water problems in this particularly complex mining system. [less ▲]

Type 1 diabetes was associated with an increase in both PP and PWV as compared to a nondiabetic population. In the diabetic population, a close correlation between the two indirect markers of arterial stiffness was found and also between each of them and age (or diabetes duration), but not in controls. These observations support the concept of an earier arterial stiffness in type 1 diabetes with rather poor glycemic control. [less ▲]

Which theoretical categories can we use to talk about an artist’s drawing? The quality of the line, the specific rhythm, the relationship between line and color, the degree of realism or the aesthetic influence of past masters: these are not easy to describe in an original way. The difficulties encountered in the traditional field of the fine arts also present themselves when considering comics because the drawing is specific and implicates a different temporality. The artists themselves regret the lack of a real aesthetic approach to their works, but we cannot simply transpose the usual discourse to the study of comics: as a young medium, this art form deserves relevant categories of analysis. My research will investigate what Aesthetics, as formal approach, could add to comics studies. I propose to read Joan Sfar’s auto-biographical notebooks published by L’association between 2002 and 2005 – in particular: Harmonica, Ukulélé, Parapluie, Piano, Caravan. These notebooks contain precious insight into his work method and his drawing. I would like to highlight several recurring themes. Sfar first criticizes the “academic drawing” he learned at school as being too “realist,” “anatomical,” and devoid of life. He explains that it took him a long time to depart from this kind of drawing. By contrast, he heartily advocates drawing directly from the perception of movement, situation, and expression, implying rapid and freehand drawing. In this context, Sfar refers to the famous illustrator Quentin Blake, who describes his career path, accompanied by relevant drawings, in La vie de la page (1995). I propose to compare Joan Sfar’s ideas on drawing with this principal influence on his work. Finally, the theory of color and light shows – in another way – the importance of the accidental and the uncalculated in his art. My arguments will be supported by various examples of Sfar’s work.

External Quality Assessment (EQA) schemes are national programmes designed to control the analytical performance of clinical laboratories and to maintain inter-laboratory variability within acceptable limits. In this context, the type of assay technique or equipment used by the participants is an important factor to take into account. The coefficient of variation (CV) is widely used in EQA to compare the reproducibility of techniques and equipments: the lower the CV, the better the analytical performance. The recent introduction of protein electrophoresis, a laboratory test profile consisting of five fractions (albumin, α1, α2, β and γ globulins) summing up to 100%, in the EQA programme (Zhang et. al. 2008) prompted us to revisit an old problem (Reyment 1960), namely the multivariate extension of the univariate CV concept, and to suggest some amendments to existing solutions. Further, the application of the multivariate CV to techniques and methods used in the assay of protein electrophoresis raises concomitant statistical problems. First, the compositional nature of electrophoretic data requires a log-ratio one-to-one transformation from the simplex to the real space (Aitchison 1982). Next, robust estimations of the mean and the covariance matrix (Rousseeuw and Van Driessen 1999) are needed to avoid the effect of outliers. The resulting robust multivariate CVs are illustrated on electrophoretic EQA material from the Belgian and French national EQA programmes to assess the analytical variability of the electrophoretic techniques used.

Consider the location-scale regression model Y=m(X) + σ(X) Ɛ where the error Ɛ is independent of the covariate X and where m and σ are unknown smooth functions. The pair (X; Y ) is subject to generalized bias selection and the response to right censoring. We construct an estimator for the cumulative distribution function of the error Ɛ, and develop a bootstrap procedure to select the smoothing parameter involved in the procedure. This method is studied via extension simulations and applied to real unemployment data. [less ▲]

Cluster analysis may be performed when one wishes to group similar objects into a given number of clusters. Several algorithms are available in order to construct these clusters. In this talk, focus will be on the generalized k-means algorithm, while the data of interest are assumed to come from an underlying population consisting of a mixture of two groups. Among the outputs of this clustering technique, a classi cation rule is provided in order to classify the objects into one of the clusters. When classi cation is the main objective of the statistical analysis, performance is often measured by means of an error rate ER(F; Fm) where F is the distribution of the training sample used to set up the classi cation rule and Fm (model distribution) is the distribution under which the quality of the rule is assessed (via a test sample). Under contamination, one has to replace the distribution F of the training sample by a contaminated one, F(eps) say (where eps corresponds to the fraction of contamination). In that case, the error rate will be corrupted since it relies on a contaminated rule, while the test sample may still be considered as being distributed according to the model distribution. To measure the robustness of classification based on this clustering proce- dure, influence functions of the error rate may be computed. The idea has already been exploited by Croux et al. (2008) and Croux et al. (2008) in the context of linear and logistic discrimination. In this setup, the contaminated distribution takes the form F(eps)= (1-eps)*Fm + eps*Dx, where Dx is the Dirac distribution putting all its mass at x: After studying the influence function of the error rate of the generalized k- means procedure, which depends on the influence functions of the generalized k-means centers derived by Garcia-Escudero and Gordaliza (1999), a diagnostic tool based on its value will be presented. The aim is to detect observations in the training sample which can be influential for the error rate. [less ▲]

Durant les dernières décennies, le domaine pharmaceutique s’est intéressé aux micelles et nanoparticules polymères celles-ci pouvant être utilisées comme vecteurs à libération contrôlée. Dans ce domaine, des copolymères amphiphiles combinant le poly(oxyde d’éthylène) (POE), polymère possédant des propriétés répulsives vis-à-vis des protéines plasmiques, et la poly-epsilon-caprolactone (PCL), un polyester aliphatique, polymère hydrophobe biocompatible et biodégradable permettant l’incorporation d’un principe actif hydrophobe, sont d’excellents candidats pour cette d’application. Jusqu’à présent, ce type de copolymère amphiphile principalement étudié est d’architecture linéaire. Récemment, notre laboratoire a développé une stratégie permettant la préparation de nouveaux copolymères greffés, composés d’un squelette principal de PCL et de greffons de POE. De plus, des agents de ciblage peuvent être introduits à l’extrémité du POE de ces copolymères amphiphiles, faisant de ceux-ci des candidats idéaux comme vecteur de troisième génération, permettant un ciblage spécifique au sein même de l’organisme. Le mannose est un agent intéressant, car il est reconnu à la surface des cellules dendritiques. Dans ce travail, la préparation de copolymères greffés fonctionnalisés par du mannose est décrite. La présence de mannose à la surface des micelles a d’abord été mise en évidence par test ELLA (Enzyme Linked Lectin Assay). Ensuite une étude plus approfondie a été réalisée par QCM-D (Microbalance à Cristal de Quartz avec Dissipation). Cette technique originale permet de mettre en évidence l’interaction entre la lectine immobilisée sur la surface du cristal de la microbalance et le mannose exposés à la périphérie des micelles du copolymère.

In September 2005, the Walloon Government decided to adopt “the Walloon Marshall Plan”, one of the priorities of which is the setting up of competitiveness clusters bringing together different contributors (businesses, private & public research centres and training centres). In this context, our aim is to understand how the businesses and the research and training centres are managing to put in place partnership dynamics in order to create innovative projects. To achieve this, we have chosen to focus primarily on the dynamics of inter-organizational learning. Consequently, within the five competitiveness clusters set up in mid-2006, we have opted to focus in particular on 4 projects which have emerged from them. The conceptual model upon which we have based our initiative is structured around this aim and makes use of various analytical benchmarks. Inspired in particular by the work of Holmqvist (2003), this model constitutes our reading and analysis framework for the projects selected from the four competitiveness clusters selected. [less ▲]

In this paper, an implementation of a model for room-acoustic predictions in COMSOL Multiphysics is presented. The model (called diffusion model) is based on the solving of diffusion equations instead of classical wave equations and allows simulating the sound propagation in complex geometries at high frequency. Instead of using COMSOL Multiplysics to solve directly the problem, a specific tool has been developed. It is composed of a user-friendly interface (I-Simpa) which manipulates all the physical data of the problem (geometries, acoustic properties and elements…) and generates an interoperability script to execute COMSOL Multiplysics via the generation of .m file scripts. Then, numerical results are processed by I-Simpa for the acoustic post-treatment and results display, like sound levels, reverberation times… [less ▲]

The proposed methodology aims at identifying a region in the space of factors that will likely provide satisfactory results during the future use of an analytical method or process in routine, through an optimization process. First, in a Bayesian framework, DS is derived from the joint predictive posterior distribution of the responses in a multivariate multiple regression problem using non-informative as well as informative prior distribution of the parameters. The case of DS in presence of highly correlated responses will be covered. Second, a multi-criteria decision is taken with respect to the pre-defined acceptance limits, aiming to identify the DS of any analytical methods or other processes. A strong link is made between acceptance limits and objective functions to optimize, using desirability functions and index. Examples based on high-performance liquid chromatography (HPLC) methods will be given, illustrating the applicability of the methodology with highly correlated and constrained responses. [less ▲]

This paper presents the heat flow model and the experimental test bench developed to optimize a new kind of heating floor. In the first part of the text is described the new kind of high reactivity emitting device for building heating and cooling. A second part illustrates the numerical model developed to evaluate the device efficiency. Finally experimental test bench implementation and results are presented. Both computational and experimental results support the use of colder water in comparison to other heating devices. This implies energy savings for building heating. [less ▲]

At high frequencies, the sound propagation can be approximated by the propagation of sound particles which are reflected and absorbed at the boundaries. This propagation follows then a transport process. In urban canyons, this transport process can be reduced to a diffusion process. The resultant model allows one to obtain the spatial distribution of the acoustical energy in a street in a few seconds using a classical finite elements program. This diffusion model has been previously validated in rectilinear streets for different geometrical and acoustical parameters. In this paper, more complex geometries such as varying cross-sections, bents and streets crossings are dealt with. As the diffusion model only models the reverberated sound field, diffraction effects on the direct sound field at streets corners are added. The obtained results are then compared to scale model experiments. [less ▲]

Impaired memory performance does not constitute the prominent deficit in frontotemporal dementia (FTD). Nevertheless, it has been suggested that some specific aspects of memory may be disrupted in FTD patients, in particular, the ability to consciously recollect the context in which information has been learned (Simons et al., 2002). The aims of the current study was to investigate the states of awareness accompanying recognition memory by asking participants to make Remember/Know/Guess judgments. Concretely, 12 FDT patients and 12 matched healthy participants studied 20 word pairs. During cued recall, each trial consisted of one word from a pair and participants had to try to recall the associated word. Finally, a 5-alternative forced-choice recognition task was given and participants had to say whether they chose a word because they recollected the study context (Remember), they knew they saw the word, without recalling anything else (Know) or they guessed (Guess). Results from the cued recall and recognition parts indicated that FTD recalled less word pairs than the controls, but had similar levels of recognition performance. Nevertheless, FTD patients gave less Remember responses than the controls, and tended to give more Guess responses. To conclude, episodic memory performance in FTD was characterised by impaired self-initiated memory retrieval processes. Although global recognition memory performance was preserved, FTD patients’ memories lacked of autonoetic consciousness and were mainly based on familiarity judgments and guessing. This pattern of results is similar to that found in patients with focal frontal lobe lesions (e.g., Wheeler et al., 1995; Wheeler & Stuss, 2003) and is consistent with the idea that the memory dysfunctions observed in FTD may stem from damage to the prefrontal cortex.
