Finding Maximum Cliques in Large Networks

S. Y. Chan, K. Morgan, J. Ugon

There are many methods to find a maximum (or maximal) clique in large networks. Due to the nature of combinatorics, computation becomes exponentially expensive as the number of ver…

Exact Counts of $C_{4}$ s in Blow-Up Graphs

S. Y. Chan, K. Morgan, J. Ugon

Cycles have many interesting properties and are widely studied in many disciplines. In some areas, maximising the counts of $k$ -cycles are of particular interest. A natural candida…

Solar Wind Charge Exchange contribution to the ROSAT All Sky Survey Maps

Y. Uprety, M. Chiao, M. R. Collier +15

DXL (Diffuse X-ray emission from the Local Galaxy) is a sounding rocket mission designed to estimate the contribution of Solar Wind Charge eXchange (SWCX) to the Diffuse X-ray Back…

The Structure of the Local Hot Bubble

W. Liu, M. Chiao, M. R. Collier +14

DXL (Diffuse X-rays from the Local Galaxy) is a sounding rocket mission designed to quantify and characterize the contribution of Solar Wind Charge eXchange (SWCX) to the Diffuse X…

The origin of the 'local' 1/4 keV X-ray flux in both charge exchange and a hot bubble

M. Galeazzi, M. Chiao, M. R. Collier +14

The Solar neighborhood is the closest and most easily studied sample of the Galactic interstellar medium, an understanding of which is essential for models of star formation and ga…

X-ray emission measurements following charge exchange between C $^{6 +}$ and H $_{2}$

M. Fogle, D. Wulf, K. Morgan +4

Lyman x-ray spectra following charge exchange between C $^{6 +}$ and H $_{2}$ are presented for collision velocities between 400 and 2300 km/s (1--30 keV/amu). Spectra were measured by…

A new search for the $K_{L} \to I ¨ ^{0} I^½ I^½$ and $K_{L} \to I ¨ ^{0} X^{0}$ decays

J. K. Ahn, K. Y. Baek, S. Banno +87

We searched for the $C P$ -violating rare decay of neutral kaon, $K_{L} \to I ¨ ^{0} I^½ I^½$ , in data from the first 100 hours of physics running in 2013 of the J-PARC KOTO experi…

The Dirac equation in the Kerr-de Sitter metric

D. Batic, K. Morgan, M. Nowakowski +1

We consider a fermion in the presence of a rotating black hole immersed in a universe with positive cosmological constant. After deriving new formulae for the event, Cauchy and cos…
