    Textualité et intertextualité des contes. Perrault, Apulée, La Fontaine, Lhéritier… de Ute Heidmann et Jean-Michel Adam se situe aux confins de deux disciplines, la littérature comparée et la linguistique. Le livre s’articule autour de deux parties, une première sous la plume de U. Heidmann et une seconde sous celle de J.-M. Adam. Les approches méthodologiques et théoriques de ces deux parties sont à la fois différentes et complémentaires. L’originalité de ce livre est, comme le souligne Del..

    Investigation of galaxies from Vorontsov-Vel'yaminov's second Atla

    No full text
    Large-scale photographs and low-dispersion spectra obtained for 43 galaxies from Part II of Vorontsov-Vel'yaminov's (1977) Atlas of Interacting Galaxies are studied in order to search for examples of clumpy irregular galaxies and to perform a morphological and spectroscopic investigation of a sample from the cited Atlas. It is found that nearly half the galaxies have a normal Hubble morphological type, that one-sixth are morphologically peculiar, that more than half the galaxies exhibit emission lines, and that the presence of emission lines is apparently independent of morphology. Interesting objects noted include two possible cases of clumpy irregular galaxies, a possible very sinous chain, two spirals with 'blown up' arms, two cases of condensations located nearly symmetrically with respect to the nucleus, and one peculiar spiral with one very bright arc or arm

    Observation of a kilogram-scale oscillator near its quantum ground state

    We introduce a novel cooling technique capable of approaching the quantum ground state of a kilogram-scale system—an interferometric gravitational wave detector. The detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO) operate within a factor of 10 of the standard quantum limit (SQL), providing a displacement sensitivity of 10<sup>−18</sup> m in a 100 Hz band centered on 150 Hz. With a new feedback strategy, we dynamically shift the resonant frequency of a 2.7 kg pendulum mode to lie within this optimal band, where its effective temperature falls as low as 1.4 μK, and its occupation number reaches about 200 quanta. This work shows how the exquisite sensitivity necessary to detect gravitational waves can be made available to probe the validity of quantum mechanics on an enormous mass scale

    Incorporation of Drosophila CID/CENP-A and CENP-C into centromeres during early embryonic anaphase.

    The centromere/kinetochore complex is indispensable for accurate segregation of chromosomes during cell divisions when it serves as the attachment site for spindle microtubules. Centromere identity in metazoans is believed to be governed by epigenetic mechanisms, because the highly repetitive centromeric DNA is neither sufficient nor required for specifying the assembly site of the kinetochore. A candidate for an epigenetic mark is the centromere-specific histone H3 variant CENP-A that replaces H3 in alternating blocks of chromatin exclusively in active centromeres. CENP-A acts as an initiator of kinetochore assembly, but the detailed dynamics of the deposition of metazoan CENP-A and of other constitutive kinetochore components are largely unknown. Here we show by quantitative fluorescence measurements in living early embryos that functional fluorescent fusion proteins of the Drosophila CENP-A and CENP-C homologs are rapidly incorporated into centromeres during anaphase. This incorporation is independent of ongoing DNA synthesis and pulling forces generated by the mitotic spindle, but strictly coupled to mitotic progression. Thus, our findings uncover a strikingly dynamic behavior of centromere components in anaphase
