New spectral classification technique for X-ray sources: quantile analysis
, 2004 We present a new technique called "quantile analysis" to classify spectral properties of X-ray sources with limited statistics. The quantile analysis is superior to the conventional approaches such as X-ray hardness ratio or X-ray color analysis to study

X-RAY PHASE ANALYSIS OF DASHNOBAD POMEGRANATE REPROCESSED EXTRACT
, 2023 Human beings have cultivated pomegranate (Punica granatum L.) for its medicinal and nutritious properties for over 4000 years. Pomegranate fruit with 2.5–three million tons of annual global production is used to manufacture a wide range of food products such as fruit juice, concentrate, anardana, jam, candies, toppings, and canned arils besides its ...

Phase-resolved spectral analysis of 4U 1901+03 during its outburst [PDF]
, 2009 The high mass X-ray binary 4U 1901+03 was reported to have the pulse profile evolving with the X-ray luminosity and energy during its outburst in February-July 2003: the pulse peak changed from double to single along with the decreasing luminosity.

EXOSAT X-ray Light Curves of SS ARI [PDF]
Journal of Astronomy and Space Sciences, 1998 We construct the X-ray light curves of the W UMa type contact binary SS Arietis (HD12929) from the EXOSAT data in HEASARC data archive. The phase dependent X-ray light curves obtained by using the ephemeris of Kaluzny & Pojmanski (1984) have been ...

Multi-wavelength spatially resolved analysis of quasi-periodic pulsations in a solar flare [PDF]
, 2008 Aims. We aim to perform a spatially resolved analysis of a quasi-periodic pulsation event from 8th May 1998 using microwave data from the Nobeyama Radioheliograph and Radiopolarimeter, and X-ray data from the Yohkoh satellite. Methods.

, 2015 Context: Be/X-ray binaries show outbursts with peak luminosities up to a few times $10^{37}\,$erg/s, during which they can be observed and studied in detail. Most (if not all) Be/X-ray binaries harbour accreting pulsars, whose X-ray spectra in many cases

Hard X-ray variability of the black-hole candidate GRO J0422+32 during its 1992 outburst [PDF]
, 1998 We have studied the hard X-ray variability of the soft X-ray transient GRO J0422+32 with BATSE in the 20-100 keV energy band. Our analysis covers 180 days following the first X-ray detection of the source on 1992 August 5, fully covering its primary and ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.
