X-ray lines and self-interacting dark matter [PDF]
, 2015 We study the correlation between a monochromatic signal from annihilating dark matter and its self-interacting cross section. We apply our argument to a complex scalar dark sector, where the pseudo-scalar plays the role of a warm dark matter candidate ...

Scientific Reports, 2019 Synchrotron generated monochromatic X-rays can be precisely tuned to the K-shell energy of high Z materials resulting in the release of the Auger electrons. In this work, we have employed this mechanism to destruct tumor spheroids.

Cycles and transitivity by monochromatic paths in arc-coloured digraphs
AKCE International Journal of Graphs and Combinatorics, 2015 A digraph D is an m-coloured digraph if its arcs are coloured with m colours. If D is an m-coloured digraph and a∈A(D), then colour(a) will denote the colour has been used on a.

Can AERONET data be used to accurately model the monochromatic beam and circumsolar irradiances under cloud-free conditions in desert environment? [PDF]
Atmospheric Measurement Techniques, 2015 Routine measurements of the beam irradiance at normal incidence include the irradiance originating from within the extent of the solar disc only (DNIS), whose angular extent is 0.266° ± 1.7 %, and from a larger circumsolar region, called the circumsolar

On the Evidence for Axion-like Particles from Active Galactic Nuclei [PDF]
, 2010 Burrage, Davis, and Shaw recently suggested exploiting the correlations between high and low energy luminosities of astrophysical objects to probe possible mixing between photons and axion-like particles (ALP) in magnetic field regions.

Journal of Combinatorial Theory, Series A, 1984 The author first gives a particularly simple proof of J. B. Kelly's theorem: If A and B are two finite sets in \(R^ d\) (\(d\geq 2)\) with every open segment joining two points in the same set containing a point of the other, then all the points of A and B lie on a line. Then he generalizes to: If A and B are finite disjoint sets and A contains \(2d+1\)

Optics Express, 2018 We present a reconfigurable, dynamic beam steering holographic metasurface aperture to synthesize a microwave camera at K-band frequencies. The aperture consists of a 1D printed microstrip transmission line with the front surface patterned into an array ...
