We report the discovery of a new gravitational lens system from the CLASS survey. Radio observations with the VLA, the WSRT and MERLIN show that the radio source B0850+054 is comprised of two compact components with identical spectra, a separation of 0.7 arcsec and a flux density ratio of 6:1. VLBA observations at 5 GHz reveal structures that are consistent with the gravitational lens hypothesi...
Established associative classification algorithms have shown to be very effective in handling categorical data such as text data. The learned model is a set of rules that are easy to understand and can be edited. However, they still suffer from the following limitations: first, they mostly use the support-confidence framework to mine classification association rules which require the setting of...
We present new high resolution and high sensitivity multi-frequency VLA radio continuum observations of the G9.62+0.19-F hot molecular core. We detect for the first time faint centimetric radio continuum emission at the position of the core. The centimetric continuum spectrum of the source is consistent with thermal emission from ionised gas. This is the first direct evidence that a newly born ...
We report evidence for persistent giant and rapid X-ray variability in the radio-quiet, ultrasoft, strong Fe ii, narrow-line Seyfert 1 galaxy IRAS 13224–3809. Within a 30 day ROSAT High Resolution Imager (HRI) monitoring observation at least five giant amplitude count rate variations are visible, with the maximum observed amplitude of variability being about a factor of 60. We detect a rise by ...
We present the near-Maximal Algorithm for Poisson-disk Sampling (nMAPS) to generate point distributions variable resolution Delaunay triangular and tetrahedral meshes in two three-dimensions, respectively. nMAPS consists of principal stages. In first stage, an initial distribution is produced using a cell-based rejection algorithm. second holes sample are detected efficient background grid fill...
Abstract The Polar beamline will make use of the small emittance new APS-U storage ring and offer extremely brilliant coherent beam variable polarization in hard x-ray range. Tailored optics experimental equipment enable high spatial resolution dichroic spectroscopy, reflectivity diffraction combination with extreme pressures, low temperatures magnetic fields. Dichroic direct ptychographic imag...
