Under the assumption that the gas mass fraction of galaxy clusters estimated out to an outer hydrostatic radius is constant, it is possible to constrain the cosmological parameters by using the angular diameter distance relation with redshift. We applied this to a sample of galaxy clusters from redshifts of 0.1 to 0.94, for which published gas and total masses are available from X-ray data. Aft...

Using HI absorption spectra taken from the recent surveys of λ21-cm line and continuum emission in the Galactic plane, the distribution of cool atomic clouds in the outer disk of the Milky Way is revealed. The warp of the midplane is clearly seen in absorption, as it is in emission, and the cool, neutral medium also shows flaring or increase in scale height with radius similar to that of the wa...

Abstract In this paper, the single event transient (SET) characteristics of advanced 16 nm SOI FinFET device are investigated. The impacts five different variables on SET response investigated, including incident position, particle LET value, characteristic radius, angle, and drain bias. It is found that 1) unlike traditional planar devices, shape changes significantly. “SET tail” caused by cha...

The central aorta acts as a compliant tube that buffers and conducts pulsatile ventricular output (7) and contributes mostly to total compliance of the arterial tree. The mathematical model introduced by O. Frank (7) describing pulse wave propagation and arterial mechanical properties assumes that the arterial tree is an elastic chamber (windkessel) in which the diastolic pressure decays expone...

The Rydberg constant is of interest due to its relation to other fundamental constants and its role in calculations of atomic energy levels. Its current relative uncertainty stands at 5.9x10^-12 [1]. However, a large discrepancy involving the proton radius and the Rydberg constant has emerged in muonic hydrogen and deuterium (“proton radius puzzle” [2]). One concern expressed by the leading aut...

Given a line segment I = [0, L], the so-called barrier, and a set of n sensors with varying ranges positioned on the line containing I, the barrier coverage problem is to move the sensors so that they cover I, while minimising the total movement. In the case when all the sensors have the same radius the problem can be solved in O(n logn) time (Andrews and Wang, Algorithmica 2017). If the sensor...

J Bone Joint Surg [Br] 2004;86-B:1047-9. Received 4 March 2003; Accepted after revision 29 August 2003 Fractures and plastic deformities of the forearm are common in children. While axial deformities are easily recognised and treated, bowing of the radius may be overlooked. Physiological bowing is essential for full rotation of the forearm. We have used the method of Schemitsch and Richards to ...

This is a technical appendix to the paper titled Cognitive Radios for Spectrum Sharing which will appear in the January issue of the IEEE Signal Processing Magazine. Due the severe space constraints the technical details had to be moved out of the paper and incorporated into this report. I.
