The Galileo spacecraft observed energetic field-aligned electron beams very close to Io during several flybys. We apply a three-dimensional magnetohydrodynamic (MHD) model of the far-field Io-Jupiter interaction to simulate for the first time the location and spatial shape of field-aligned electron beams. Io continuously generates MHD waves by disturbing the Jovian magnetoplasm. Currents carried by Alfven waves propagate predominantly along the magnetic field lines. As the number of charge carriers decreases along the travel path, electrons are accelerated toward Jupiter. These energetic electrons precipitate into the Jovian ionosphere, visible as prominent Io footprint emission. Electrons are also accelerated toward Io and form the equatorial beams observed by the Galileo spacecraft. Unlike the beam formation, the position and spatial structure of these beams have not been addressed in detail before. We use a 3-D MHD model with initial conditions corresponding to the individual Galileo flyby and determine the spatial morphology of the beams in Io's orbital plane. Our results for the beam locations are in good agreement with the Galileo Energetic Particle Detector observations. We find that the ratio of the one-way travel time of the Alfven wave from Io to Jupiter and the convection time of the plasma past the obstacle controls the location of the beam. This leads to the conclusion that at other satellites with other plasma environments, the electrons might not be close to the satellite but can be shifted significantly downstream along its plasma wake. Thus, the future search for electron beams near a satellite should be further extended to the wake region. [less ▲]

The Galileo spacecraft measured hot field aligned electron beams near Io during three flybys. We apply our 3D MHD model of the Io-Jupiter interaction to constrain the location and shape of field aligned electron beams for the individual flyby scenarios. Io continuously generates MHD waves by disturbing the Jovian magnetoplasma. Currents carried by Alfvén waves propagate predominantly along the magnetic field lines. The waves accelerate electrons as the number of charge carriers decreases on their way to Jupiter. These energetic electrons precipitate into the Jovian ionosphere, visible as prominent Io footprint emission in the Jovian aurora. On the other hand electrons have to be accelerated upward to form the beams measured by Galileo. Unlike the beam formation, the position and spatial structure of these beams has been poorly discussed. We adopt our 3D MHD model initial conditions to the individual flyby scenario and determine the spatial morphol- ogy of beams in Io’s orbital plane. We compare our findings to Galileo observations and find very good agreement. Moreover, we use our model to further investigate in detail a recent concept which involves cross-hemisphere electron beams to explain certain auroral features of the Io footprint emission such as a leading spot and secondary spots [Bonfond et al., 2008]. Our results indicate that besides geometrical properties, such as Io’s position in the torus, the incoming plasma density controls the travel path and topology of an electron beam. [less ▲]

Consider the heteroscedastic model Y =m (X) +sigma(X)epsilon, where epsilon and X are independent, Y is subject to right censoring, m (center dot) is an unknown but smooth location function (like e.g. conditional mean, median, trimmed mean...) and sigma(center dot) an unknown but smooth scale function. In this paper we consider the estimation of m(center dot) under this model. The estimator we propose is a Nadaraya-Watson type estimator, for which the censored observations are replaced by 'synthetic' data points estimated under the above model. The estimator offers an alternative for the completely nonparametric estimator of m (center dot), which cannot be estimated consistently in a completely nonparametric way, whenever high quantiles of the conditional distribution of Y given X = x are involved. We obtain the asymptotic properties of the proposed estimator of m (x) and study its finite samplebehaviour in a simulation study. The method is also applied to a study of quasars in astronomy.

La notion de location immobilière en matière de T.V.A. s’écarte expressément des concepts traditionnels du Code civil, et reçoit désormais, pour l’application des directives européennes et des dispositions de droit interne qui en sont issues, une acception spécifique, la jurisprudence européenne l’ayant érigée en «notion autonome de droit communautaire». Dans cet ouvrage, l’auteur s’attache à cerner les contours de cette notion à la lumière du droit fiscal européen, avant de définir la portée du principe de l’exemption de T.V.A. applicable à la location immobilière. Il analyse ensuite de manière détaillée le régime des diverses formes de mise à disposition d’immeubles qui, par exception, restent néanmoins soumises à la taxe tout en conférant à l’assujetti le droit de déduire les taxes payées en amont, droit exclu en cas d’exemption. Enfin, l’auteur examine le régime de certaines opérations apparentées à la location immobilière et les incidences concrètes, en matière de T.V.A., des travaux effectués par un locataire dans l’immeuble loué, de même que les particularités relatives à la déduction de la T.V.A. par le locataire d’une partie d’immeuble en copropriété forcée. Les nombreuses circulaires et décisions administratives relatives à la matière sont relevées et analysées. Quant aux décisions de jurisprudence, parmi lesquelles un nombre appréciable de décisions inédites, elles font l’objet d’un commentaire systématique. [less ▲]

We have investigated the DNA distribution within the rat oocyte nucleolus during the early stages of follicular growth by means of the in situ terminal deoxynucleotidyl transferase method. In the fibrillogranular nucleolus, label is visualized on small clumps of peri- and intranucleolar chromatin. Such labeled clumps are frequently observed inside the interstices surrounding the fibrillar centers. Label is also consistently found in the fibrillar centers whereas the dense fibrillar component and the granular component are devoid of gold particles. These results contradict earlier data but conform with other recent immunocytochemical observations, obtained in nucleoli of a variety of somatic cell types, concerning the correlation between structure and function in the nucleolus.

The nucleolus is the morphological visualization of ribosome biogenesis. The spatial distribution of nucleolar DNA has been investigated in Ehrlich tumor cells by various immunogold labelling techniques. The DNase 1-sensitive regions within the nucleolus have been identified by in situ nick-translation at the ultrastructural level. The precise nucleolar location of rDNA and rRNA has been further specified by in situ hybridization and electron microscopy. Our results indicate that the fibrillar centers are the sole nucleolar structures where DNase 1-hypersensitive sequences, rDNA and rRNA are located together. These findings strongly suggest that rRNA gene transcription takes place within the confines of the fibrillar center, probably close to the boundary regions to the surrounding dense fibrillar component.

Eleven subjects were equipped with a cluster of 120 markers on the scapula. Forward humeral elevation was then performed. Robust estimators are used in order to eliminate high deformation. Results underline the modification of the best cluster during elevation. Markers located on the lateral posterior part of the acromion were identified. They could be the best ones to measure dynamic scapula rotation during entire elevation. [less ▲]

In location-based services (LBSs), the service is provided based on the users' locations through location determination and mobility realization. Most of the current location prediction research is focused on generalized location models, where the geographic extent is divided into regular-shaped cells. These models are not suitable for certain LBSs where the objectives are to compute and present on-road services. Such techniques are the new Markov-based mobility prediction (NMMP) and prediction location model (PLM) that deal with inner cell structure and different levels of prediction, respectively. The NMMP and PLM techniques suffer from complex computation, accuracy rate regression, and insufficient accuracy. In this paper, a novel cell splitting algorithm is proposed. Also, a new prediction technique is introduced. The cell splitting is universal so it can be applied to all types of cells. Meanwhile, this algorithm is implemented to the Micro cell in parallel with the new prediction technique. The prediction technique, compared with two classic prediction techniques and the experimental results, show the effectiveness and robustness of the new splitting algorithm and prediction technique.

Eighteen core samples from PETROBRAS well 1-JD-1-AM (Jandiatuba area. Solimoes Basin. northwestern Brazil) have been studied for miospores. Fifty-three species are identified. This assemblage is tentatively correlated with the Z Phylozone of the BZ Oppel Zone (Steemans, P., 1989. Palynostratigraphie de l'Eodevonien dans l'ouest de l'Europe. Professional Paper. Memoires Explicatifs pour les Caries Geologiques and Mineralogiques de la Belgique, 27, pp. 453.), dated late Lochkovian, This is in accordance with previous age determinations based on chitinozoans and acritarchs. Numerous representatives of the miospore genus Dictyotriletes are observed. These enable recognition of the Dictyotriletes emsiensis morphon. an informal classification unit which includes Dictyotriletes granulatus, D. emsiensis, Dictyotriletes cf. subgranifer, specimens previously misassigned to D. subgranifer and some Dictyotriletes spp. provisionally left in open nomenclature. Since all intermediate forms from typical D. granulatus to typical D. emsiensis coexist. it is currently difficult to determine the base of "F" Interval Biozone in South America as originally defined in Western Europe. It is suggested. therefore. that the base of the "Ems" Biozone defined in Brazil cannot be correlated with the base of die "E" Biozone. Instead. it be included in an interval of uncertainty ranging from the European "Si" to "E" Biozones. Indeed. the underlying "NsZ" Biozone from South America, contains species not known below the "Si" Biozone. Here, the D. emsiensis morphon Assemblage Zone is erected, which may, be coeval with the "N" through "E" Biozones of Western Europe. The PISA palynoflora from the Parana Basin is also attributed to this new biozone. However, in the absence of species observed in the "BZ" Biozone (and also in the Solimoes Basin). the PISA assemblage could be somewhat older than that of well 1-JD-1-AM. (C) 2004 Elsevier B.V.
