Lecomte (Prog Theor Phys Suppl 144:125–132, 2001) conjectured the existence of a natural and conformally invariant quantization. In Mathonet and Radoux (Existence of natural and conformally invariant quantizations of arbitrary symbols, math.DG 0811.3710), we gave a proof of this theorem thanks to the theory of Cartan connections. In this paper, we give an explicit formula for the natural and conformally invariant quantization of trace-free symbols thanks to the method used in Mathonet and Radoux and to tools already used in Radoux [Lett Math Phys 78(2):173–188, 2006] in the projective setting. This formula is extremely similar to the one giving the natural and projectively invariant quantization in Radoux. [less ▲]

In [Prog Theor Phys Suppl 49(3):173–196, 1999], Lecomte conjectured the existence of a natural and projectively equivariant quantization. In [math.DG/0208171, Submitted], Bordemann proved this existence using the framework of Thomas–Whitehead connections. In [Lett Math Phys 72(3):183–196, 2005], we gave a new proof of the same theorem thanks to the Cartan connections. After these works, there was no explicit formula for the quantization. In this paper, we give this formula using the formula in terms of Cartan connections given in [Lett Math Phys 72(3):183–196, 2005]. This explicit formula constitutes the generalization to any order of the formulae at second and third orders soon published by Bouarroudj in [Lett Math Phys 51(4):265–274, 2000] and [C R Acad Sci Paris Sér I Math 333(4):343–346, 2001].

Population differentiation of alien invasive plants within their non-native range has received increasingly more attention. Common gardens are typically used to assess the levels of genotypic differentiation among populations. However, in such experiments, environmental maternal effects can influence phenotypic variation among individuals if seed sources are collected from field populations under variable environmental regimes. In the present study, we investigated the causes of an altitudinal cline in an invasive plant. Seeds were collected from Senecio inaequidens (Asteraceae) populations along an altitudinal gradient in southern France. In addition, seeds from the same populations were generated by intra-population crossings in a climatic chamber. The two seed lots were grown in a common garden in Central Belgium to identify any evidence of environmentally induced maternal effects and/or an altitudinal cline in a suite of life-history traits. Results failed to detect any environmental maternal effects. However, an altitudinal cline in plant height and above-ground biomass was found to be independent of the maternal environment. [less ▲]

Gas turbine design, development, monitoring and maintenance are widely based on numerical simulations of the steady and transient engine performance. Most of the equations that are solved in the simulation programs involve the thermodynamic properties of the fluid flowing through the engine. These properties depend on temperature, pressure, humidity and fuel dosage. As the solution of chemical equilibrium is not compatible with real-time computations, a chemical solver is used off-line to generate a large database which neural networks are trained on. These networks are built on radial basis functions such as multiquadrics. A forward selection approach is used to select data points from the training set as the centers of the transfer functions. The selection stops when the prediction error starts growing. The resulting networks for specific heat and enthalpy of the gas mixture are 3 orders of magnitude faster than the chemical solver. In order to further increase the efficiency and the generalization capabilities of the model, an external optimization solver has been used to tune the shape of the transfer functions. Several solutions are proposed and preliminary results are presented. [less ▲]

In order to build a digital edition of the upcoming volumes of the Atlas Linguistique de la Wallonie, we have decided to make use of the Ontology Web Language as described by the World Wide Web Consortium. We aim to develop a software meant to help the writing of onomasiological articles. It should allow us to describe located dialectal forms and progressively define groups of them, according to the way they resemble each other (e. g., from an etymological, morphological or phonetic point of view). The software-assisted process would then conform to methodological requirements of traditional scientific work, as it has thus far. OWL provides an easy way of defining form lists and grouping them afterwards. [less ▲]

L'article traite de l'évolution dans le temps des formes d’exploitation de l'arganier par les populations locales au niveau de la région d'Essaouira (Maroc). Les principaux résultats montrent que la découverte de la valeur marchande de l’arganier, par les locaux, a entrainé un changement au niveau de leurs représentations vis-à-vis de cet arbre. En conséquence, de nouvelles formes d’exploitation de cette ressource sont en train de prendre place engendrant de nouvelles relations à l’arbre et à ses produits. Dans de nombreux cas, ces nouvelles formes d’exploitation risquent de porter préjudices à ces ressources et même à leur gestion communautaire si cette exploitation n’est pas repensée dans le cadre d’une gestion et utilisation durable de l’écosystème en entier.

Introduction : Le dossier de santé informatisé (DSI), utilisé quotidiennement en soins primaires, peut constituer un instrument de récolte de données utilisables localement pour l’amélioration de la qualité des soins et, à une plus grande échelle, une base de données épidémiologiques. Malgré une politique de promotion du DSI de la Fédération des Maisons médicales belges francophones, son utilisation reste très marginale. Méthodes : Huit maisons médicales motivées par l’informatisation de leur dossier ont été rencontrées. Des indicateurs quantitatifs d’utilisation du DSI ont été mesurés. Une évaluation qualitative des résistances à l’informatisation et des solutions pouvant y être apportées a été réalisée par la technique du groupe nominal. Résultats : L’utilisation du DSI reste faible, sauf exception. Les solutions proposées ont pu être regroupées en 5 catégories : éthique (confidentialité, relation avec le patient, relation du thérapeute avec la machine), formation (à l’informatique, à la logique classificatoire, formation accessible), recherche de sens (envie d’utiliser les outputs locaux dans des projets d’amélioration de la qualité des soins, comparaison avec d’autres praticiens, encadrement local), pratique (amélioration du logiciel, amélioration de l’organisation interne des équipes, gestion du temps passé à l’encodage des données) et pluridisciplinarité (coordination entre secteurs, effort soutenu par l’ensemble de l’équipe, projets communs). Discussion : Les praticiens sont prêts à s’informatiser s’ils en retirent des bénéfices immédiats (connaissance de leur patientèle et de leur fonctionnement d’équipe). Ils ont exprimé le besoin de disposer d’un outil simple à utiliser, qui ne leur fasse pas perdre de temps et qui respecte leurs spécificités de travail et d’organisation (équipe pluridisciplinaires et autogérées). Ils ont exprimé le besoin d’un soutien extérieur, sous forme de formations adaptées et d’encadrement pour la gestion des données. Les préoccupations de type éthique (sécurité, transfert de données, place de l’ordinateur dans la relation avec le patient) sont étonnamment peu présentes. [less ▲]
