A survey of molecular gas content of galaxies at 0 . 08 < z < 1 . 06

The study of high redshift galaxies has made tremendous progress in the last few years. In order to understand their evolution, it is important to probe the gas content of distant “normal” galaxies beyond z ∼ 0.3. We searched for CO emission from a sample of galaxies in the redshift range of 0.35 to 1.06. Given the current limited sensitivity, we can only place upper limits to the gas content o...

Design of LDPC Codes: A Survey and New Results

This survey paper provides fundamentals in the design of LDPC codes. To provide a target for the code designer, we first summarize the EXIT chart technique for determining (near-)optimal degree distributions for LDPC code ensembles. We also demonstrate the simplicity of representing codes by protographs and how this naturally leads to quasi-cyclic LDPC codes. The EXIT chart technique is then ex...

In this note we have considered a relativistic Nambu-Goto model for a particle in AdS metric. With appropriate gauge choice to fix the reparameterization invariance, we recover the previously discussed [7] " Exotic Oscillator ". The Snyder algebra and subsequently the κ-Minkowski spacetime are also derived. Lastly we comment on the impossibility of constructing a noncom-mutative spacetime in th...
