A method for testing the cosmic homogeneity with Shannon entropy
We propose a method for testing cosmic homogeneity based on the Shannon
entropy in Information theory and test the potentials and limitations of the
method on Monte Carlo simulations of some homogeneous and inhomogeneous 3D
point process in a finite region of space. We analyze a set of N-body
simulations to investigate the prospect of determining the scale of homogeneity
with the proposed method and show that the method could serve as an efficient
tool for the study of homogeneity.Comment: 7 pages, 3 figures, Accepted for publication in MNRA

Proposal to Encode the Pau Cin Hau Alphabet in ISO/IEC 10646
This is a proposal to encode the Pau Cin Hau script in the international character encoding standard Unicode. This script was published in Unicode Standard version 7.0 in June 2014. Pau Cin Hau is a liturgical script for the Laipian religion. It was originally designed to write the Tedim language, a Chin language in western Myanmar, but the script also includes characters for representing sounds of other Chin languages
Unparticle Decay of Neutrinos and its Possible Signatures at a Detector for (3+1) Flavour Framework
We consider a scenario where ultra high energy neutrinos undergo unparticle
decay during its passage from its cosmological source to Earth. The idea of
unparticle had been first proposed by Georgi by considering the possible
existence of an unknown scale invariant sector at high energies and the
unparticles in this sector manifest itself below a dimensional transmutation
scale . We then explore the possible signature of such
decaying neutrinos to unparticles at a square kilometer detector such as
IceCube.Comment: 20 pages LaTeX, 5 eps figure
