X-ray reflection in a sample of X-ray bright ultraluminous X-ray sources [PDF]

Monthly Notices of the Royal Astronomical Society, 2010
We apply a reflection-based model to the best available XMM-Newton spectra of X-ray bright UltraLuminous X-ray (ULX) sources (NGC 1313 X-1, NGC 1313 X-2, M 81 X-6, Holmberg IX X-1, NGC 5408 X-1 and Holmberg II X-1). A spectral drop is apparent in the data of all the sources at energies 6-7 keV.

Disk-Jet Connection in Cygnus X-3 [PDF]

, 2001
We present the results of a detailed correlation study between the soft X-ray, hard X-ray, and radio emission (obtained from RXTE ASM, BATSE, and GBI observations, respectively) of the bright radio emitting Galactic X-ray binary Cygnus X-3.

Intra-nosological diagnosis of endometrial cancer

Опухоли женской репродуктивной системы, 2014
The study is based on the analysis of comprehensive ultrasound examinations of 158 patients with a verified diagnosis of endometrial cancer (EC). It was conducted, by taking into account the concept of 3 types of microinvasive EC growth. Echosemiotics in

Scalable and accurate multi-GPU-based image reconstruction of large-scale ptychography data

Scientific Reports, 2022
While the advances in synchrotron light sources, together with the development of focusing optics and detectors, allow nanoscale ptychographic imaging of materials and biological specimens, the corresponding experiments can yield terabyte-scale volumes ...

Magnetar-like X-ray Bursts from an Anomalous X-ray Pulsar [PDF]

, 2002
Anomalous X-ray Pulsars (AXPs) are a class of rare X-ray pulsars whose energy source has been perplexing for some 20 years. Unlike other, better understood X-ray pulsars, AXPs cannot be powered by rotation or by accretion from a binary companion, hence ...
