... International Journal of Bifurcations and Chaos , 1998, vol. ... Impulsive synchronization of chaotic dynamic systems has some important applications to chaotic secure communication and chaotic spread-spectrum communication systems. In this paper we present some experimental results on impulsive synchronization between two Chua's circuits. ... The robustness of impulsive synchronization with respect to variations in the frequency and the width of impulses is studied. ...

... Neutral Hydrogen 21cm line emission is widely used to chart the warm and cool diffuse components of the interstellar medium. ... The ongoing Canadian Galactic Plane Survey (CGPS) meets these criteria to an unprecedented degree, permitting the comparison of HI, CO, and dust features at arcminute scales over hundreds of square of degrees of the Milky Way. We will present the first results of an investigation of neutral Hydrogen self-absorption features in the CGPS dataset. ...

... Cross-shaped galaxy ZGC 2315+03 (Fig.1) has been described by Zwicky (1971) as ``post-eruptive or the result of the crossing of a compact galaxy through an edge-on spiral'' . This object was included in the Polar-Ring Catalog (C-71) by Whitmore et al. (1990) as a possible candidate for Polar-Ring Galaxies (PRG). ... One of them is galaxy 'disk' and the other is 'polar-ring'. ... The facts against the polar-ring nature of ZGC 2315+03 can be summarized as follows: . ...

... Here we discuss our survey methods, identification procedure and first results. Our survey is found to be efficient at finding flat-spectrum radio-loud quasars (FSRQs, 59 of our first 85 IDs) and BL Lacertae objects (22 of our first 85 IDs), a figure which is comparable to or greater than that achieved by other radio and X-ray survey techniques. ... Particularly important is the identification of a large population of FSRQs ( of DXRBS FSRQs) with ratios of X-ray to radio luminosity . ... FSRQs . ...

The bulge is one of the oldest, yet very metal-rich Galactic components suggesting that it experienced early, rapid chemical enrichment. Yet, the first, metal-poor stars to have formed in the Universe are predicted to be found in this central region of the Milky Way. ... The chemical abundances of our candidates (at [Fe/H] of -1.5 to -2.6 dex) vastly overlap with those of halo stars and our sample also contains one CEMP-s and a CH-star - the first detections of such objects in the bulge. ...

... Previous: Predictive Mining of Time Series Data in Astronomy . ... This paper describes a method for determining the geometric distortion of the FUSE detectors using data from the in-orbit stimulation lamp exposures. A wavelet approach is used to smooth the image, while enhancing the shape of the shadows cast by the QE and plasma grids suspended above the detectors. ...
