We present a study of the spectral variability of the Seyfert I galaxy MCG–6-3015 based on the two long XMM-Newton observations from 2000 and 2001. The X– ray spectrum and variability properties of the 2001 data have previously been well described with a two-component model consisting of a variable power law and a much less variable reflection component, containing a broad relativistic iron lin...

Six glitches have been recently observed in the rotational frequency of the young pulsar PSR B1737−30 (J1740−3015) using the 25-m Nanshan telescope of Urumqi Observatory. With a total of 20 glitches in 20 years, it is one of the most frequently glitching pulsars of the ∼1750 known pulsars. Glitch amplitudes are very variable with fractional increases in rotation rate ranging from 10 to 10. Inte...

We investigate the electronic, magnetic, and orbital properties of La0.5Ca0.5MnO3 perovskite by means of an ab initio electronic structure calculation within the Hartree-Fock approximation. Using the experimental crystal structure reported by Radaelli et al. [Phys. Rev. B 55, 3015 (1997)]], we find a charge-ordering stripelike ground state. The periodicity of the stripes, and the insulating mag...

The linguistic annotation of noun-verb complex predicates (also termed as light verb constructions) is challenging as these predicates are highly productive in Hindi. For semantic role labelling, each argument of the noun-verb complex predicate must be given a role label. For complex predicates, frame files need to be created specifying the role labels for each noun-verb complex predicate. The ...

There is a growing body of evidence in support of sleep-dependent memory consolidation and plasticity. However, there are also examples of memory development and plasticity in the absence of sleep, casting doubt on an exclusive sleep-dependent memory hypothesis. As CMLS, Cell. Mol. Life Sci. 61 (2004) 3009–3015 1420-682X/04/243009-07 DOI 10.1007/s00018-004-4351-1 © Birkhäuser Verlag, Basel, 200...

The X-ray spectrum obtained by Tanaka et al from a long observation of the active galaxy MCG63015 shows a broad iron K line skewed to low energies. The simplest interpretation of the shape of the line is that it is due to doppler and gravitational redshifts from the inner parts of a disk about a massive black hole. Similarly broad lines are evident in shorter observations of several other activ...
