We report on an analysis of high S/N ratio UBV multicolour photometry of the bright pulsating sdB star Balloon 090100001 gathered at the Canada-France-Hawaii Telescope with the help of the Montreal 3-channel photometer LAPOUNE. Through an application of the color-amplitude method described in Randall et al. (2005), we were able to identify the degree index ℓ of several individual pulsation modes. These identifications provide extremely useful constraints on possible seismic models for Balloon 090100001. [less ▲]

Martian basalts can be classified in at least two geochemically different families: enriched and depleted shergottites. Enriched shergottites are characterized by higher incompatible element concentrations and initial 87Sr/86Sr and lower initial 143Nd/144Nd and 176Hf/177Hf than depleted shergottites. It is now generally admitted that shergottites result from the melting of at least two distinct mantle reservoirs. Some of the olivine-phyric shergottites (either depleted or enriched), the most magnesian Martian basalts, could represent primitive melts, which are of considerable interest to constrain mantle sources. Two depleted olivine-phyric shergottites, Yamato 980459 and Nothwest Africa (NWA) 5789, are in equilibrium with their most magnesian olivine and their bulk rock compositions are inferred to represent primitive melts. Larkman Nunatak 06319 and NWA 1068, the most magnesian enriched basalts, have bulk Mg# that are too high to be in equilibrium with their olivine megacryst cores. Parental melt compositions have been estimated by subtracting the most magnesian olivine from the bulk rock composition, assuming that olivine megacrysts have partially accumulated. However, because this technique does not account for the actual petrography of these meteorites, we used image analysis to study these rocks history, reconstruct their parent magma and understand the nature of oli-vine megacrysts. Our image analysis results are supported by a series of high-pressure experiments performed on LAR 06319 bulk rock composition to test if it could represent a primitive melt, and understand its crystallization history.

As a result of a set of public policies and of the emergence of various social movements as of 1952 and especially in the years 1994 to 2006, Bolivia has known one of the most important processes of territorial restructuring and re organization of all its state structures. This article tackles the specific characteristics of the major transformations of the country in a period of more than 50 years; a period that led to the rise of what is now called the “Plurinational State of Bolivia”. This is done by analyzing the most important effects of certain public policies implemented between 1950 and 2010. [less ▲]

In this paper we introduce a fuzzy chart for variables which is used in situations when uncertainty and randomness are combined. It is showed that the Shewhart chart’s control limits must be adjusted in these situations. However, this chart is based on a fuzzy acceptance region and this method arises when a decision should be made by referring to the grade of a sample statistic belonging to the fuzzy acceptance region.

We consider here two approaches which have been proposed in the literature to obtain diabatic states from ab initio calculations. First by calculating explicitely the coupling vector g which describes the nonadiabatic interaction between the adiabatic states. Second, by some extrapolation process of the wavefunctions obtained at a particular reference point. The coupling vector is a sum of three contributions. The first two represent the the change in character of the adiabatic states in the region of nonadiabatic coupling due the variation of the CI and LCAO coefficients, whereas the third results from the translation of the atomic orbitals with the moving nuclear centers. Criteria have been given to recognize when it is possible to transform a set of CI wave functions into a pair of useful diabatic states. A particularly favorable situation is obtained when the interacting electronic states are doubly excited with respect to each other. Within the two-states approximation, the first term, depending on the CI coefficients, is strictly irrotational and never gives rise to problems. One can expect situations where it is also true for the second term depending on the LCAO coefficients. However, the third term of the coupling can never be described as a rotation of two diabatic functions. Nevertheless, the latter contribution can frequently be neglected, at least when the coupling is strong. The theory of the electron transfer factors (ETF's) provides further insight into the problem and confirm our conclusions. [less ▲]

This paper presents a tutorial introduction to the construction of finite-automata on infinite words from linear-time temporal logic formulas. After defining the source and target formalisms, it describes a first construction whose correctness is quite direct to establish, but whose behavior is always equal to the worst-case upper bound. It then turns to the techniques that can be used to improve this algorithm in order to obtain the quite effective algorithms that are now in use. [less ▲]

This article provides a discussion on the importance of knowledge in early childhood education and also the role of knowledge dissemination process in the field. From the question of giving more freedom of movement, knowledge about this topic used in a Belgian curriculum, the article illustrates the importance of considering practice not as an application of theory, but as a co-construct and complex process that combines it with other resources in context. It illustrates the importance of going further than the production of knowledge to create appropriate practice in service. [less ▲]

We describe the construction of an ovine BAC contig spanning a 4.6 centimorgan (cM) chromosome segment known to contain the callipyge (CLPG) locus. The contig comprises 21 ovine BAC clones jointly covering approximately 900 kilobases (Kb). Two gaps in the BAC contig, spanning 10 and 7.5 Kb, respectively, were bridged by long range PCR. The corresponding chromosome region was shown to be characterized by an unusually low Kb to cM ratio (164 Kb/cM) and a high density of Not1 sites (1:126 Kb) possibly reflecting a high gene density in the corresponding chromosome region. Equivalent amplification of 64 sequence tagged sites spanning the corresponding region from homozygous +/+ and CLPG/CLPG individuals disproves the hypothesis of a major deletion causing the CLPG mutation.

In this paper, we emphasize three different techniques for the growth of fractal trees with a desired fractal dimension D-f. The three different growths are due to the influence of (i) stretched branches, (ii) dead ends, or (iii) a variable branching rate. Several examples are given. We point out that geometrical and physical properties (skeleton dimension, percolation exponents, self-avoiding walk) of fractal tress depend strongly on their type. The most striking result is that the critical exponents at the percolation transition are nonuniversal since they depend on the tree type. The critical exponents depend on D-f for trees of types (ii) and (iii). [less ▲]

In clinical neuropsychology, different rehabilitation techniques – e.g., vanishing cues, spaced retrieval, errorless learning – developed for patients with memory impairments are considered to make use of the preserved implicit memory abilities shown by these patients, and notably the perceptual priming effects (Harrison et al., 2007). It might be therefore important for clinician neuropsychologists to determine whether these abilities are preserved or not in their patients. However, and quite surprisingly, assessment tools aimed at assessing implicit memory abilities in brain damaged patients are lacking. The aim of this study was to build and validate a new perceptual priming task – the contrasted word task – which could be used by neuropsychologists in their clinical practice. Seventy-two young healthy participants were included in this study, and were administered the contrasted word task in which 60 words counterbalanced in 2 orders and 3 types of priming (Visual; Auditory; New) emerged gradually from a white background on a computer screen. Subjects were asked to press the response key when they thought they had recognized the word. Results show a perceptual priming effect which is specific to the exposure modality (i.e., no inter-modality transfer), proving the efficacy of the contrasted word task to highlight a facilitated identification for words that were shown previously, and confirming the perceptual specificity of the priming effect (Schacter, 1992).
