X-rays are electromagnetic waves with wavelengths of 0.1 to several 10 nm and energies of 0.1–100 keV (Fig. 1). X-rays with the shorter wavelengths are called hard X-rays and have a high transmission ability, while X-rays with the longer wavelengths are called soft X-rays. Usually, X...
Two methyl-methanesulfonate-sensitive strains have been isolated, one of which, M10, was cross-sensitive to X-rays as reported before. Sensitivities of parental L5178Y, M10, and newly isolated MS-1 cells to various mutagens were examined... T Shiomi,N Heida-Shiomi,K Sato - 《Mutation Research...
gamma rays: burstsX-rays: burstsGamma-ray bursts (GRBs) can be divided into three groups: short-, intermediate- and long-duration bursts. While the progenitors of the short and long ones are relatively known, the progenitors of the intermediate-duration bursts (IBs) are generally unknown. ...
X-rays, MRIs and CT scans have a few similarities. All three are a type of imaging scan. You can have both x-rays and CT scans completed within minutes. All three imaging tools can be used to help with the diagnosis of one or more medical conditions. You need to remain still for al...
X-Rays: StarsThe spin periods of the ten observed Anomalous X-ray Pulsars and Soft Gamma-ray Repeaters lie in the very narrow range 6-12 s. We use a point likelihood technique to assess the constraints this clustering imposes on the birth period and on the final period of such systems. ...
Chromoscope lets you explore our Galaxy (the Milky Way) and the distant Universe in a range of wavelengths from X-rays to the longest radio waves. - slowe/Chromoscope
We describe measurements of the yields and energy distributions of the K series of characteristic x rays of the fragments from fission of U by neutrons of energy 3.5 MeV. The results are compared with the well-known results for thermal-neutron fission. The similarities and differences in the pr...

Preprocessing is an essential task for the correct analysis of digital medical images. In particular, X-ray imaging might contain artifacts, low contrast, diffractions or intensity inhomogeneities. Recently, we have developed a procedure named PACE that
The classic black hole candidate Cygnus X-1 exhibits many similarities to Galactic jet sources (micro-quasars) in soft gamma and hard X-ray rays. This has fuelled suspicions that radio jets also may be present in Cygnus X-1. The lack of radio flaring in Cygnus X-1 has been associated ...
