Statistical properties of sampled networks by random walks
Sooyeon Yoon, Sungmin Lee, Soon-Hyung Yook +1
We study the statistical properties of the sampled networks by a random walker. We compare topological properties of the sampled networks such as degree distribution, degree-degree…
Dirac Quantization of Restricted QCD
Y. M. Cho, Soon-Tae Hong, J. H. Kim +1
We discuss the quantization of the restricted gauge theory of SU(2) QCD regarding it as a second-class constraint system, and construct the BRST symmetry of the constrained system…
Blending in Future Space-based Microlensing Surveys
Cheongho Han, Byeong-Gon Park, Ho-Il Kim +1
We investigate the effect of blending in future gravitational microlensing surveys by carrying out simulation of Galactic bulge microlensing events to be detected from a proposed s…
Isospin particle on with arbitrary number of supersymmetries
Soon-Tae Hong, Joohan Lee, Tae Hoon Lee +1
We study the supersymmetric quantum mechanics of an isospin particle in the background of spherically symmetric Yang-Mills gauge field. We show that on the number of supers…
Diffusive Capture Process on Complex Networks
Sungmin Lee, Soon-Hyung Yook, Yup Kim
We study the dynamical properties of a diffusing lamb captured by a diffusing lion on the complex networks with various sizes of . We find that the life time <T>$ of a lamb scal…
Microlens OGLE-2005-BLG-169 Implies Cool Neptune-Like Planets are Common
A. Gould, A. Udalski, D. An +33
We detect a Neptune mass-ratio (q~8e-5) planetary companion to the lens star in the extremely high-magnification (A~800) microlensing event OGLE-2005-BLG-169. If the parent is a ma…
