The entire dataset of the GRANAT/SIGMA observations of Cyg X-1 and 1E1740.7-2942 in 1990–1994 was analyzed in order to search for correlations between primary observational characteristics of the hard X-ray (40–200 keV) emission – the hard X-ray luminosity L X , the hardness of the spectrum (quantified in terms of the best-fit thermal bremsstrahlung temperature kT) and the rms of short-term flu...
We present C-Sibelia, a highly accurate and easy-to-use software tool for comparing two closely related bacterial genomes, which can be presented as either finished sequences or fragmented assemblies. C-Sibelia takes as input two FASTA files and produces: (1) a VCF file containing all identified single nucleotide variations and indels; (2) an XMFA file containing alignment information. The soft...
The superficial L1 layer of Mycobacterium intracellulare serovar 20 was detected by immunocytochemical procedures based on C-mycoside glycopeptidolipid (GPL) antigens. Specific immune serum was produced by injecting a GPL-methylated bovine serum albumin complex into rabbits with Freund incomplete adjuvant. The resulting antibodies were used to label serovar 20 with goat anti-rabbit immunoglobul...
The presence of a polar species of glycopeptidolipid (GPL) in carbon-starved Mycobacterium smegmatis has been reported previously. In this study, the complete structure of this GPL is established with the help of MALDI-TOF (matrix assisted laser desorption/ionization time of flight) and ESI (electrospray ionization) -MS, (13)C-SEFT (spin echo Fourier transform) -NMR spectroscopy, and HPLC analy...
We present an analysis of long term X-ray monitoring observations of Circinus X-1 (Cir X-1) made with four different instruments: Vela 5B, Ariel V ASM, Ginga ASM, and RXTE ASM, over the course of more than 30 years. We use Lomb-Scargle periodograms to search for the ∼16.5 day orbital period of Cir X-1 in each of these data sets and from this derive a new orbital ephemeris based solely on X-ray ...
We study theoretical interpretations of the ∼150-d (superorbital) modulation observed in Xray and radio emission of Cyg X-1 in the framework of models connecting this phenomenon to precession. Precession changes the orientation of the emission source (either disc or jet) relative to the observer. This leads to emission modulation due to an anisotropic emission pattern of the source or orientati...
