On Separation for Multiple Access Channels [PDF]

open access: yes, 2007
We examine the issue of separation for multiple access channels. We demonstrate that source-channel separation holds for noisy multiple access channels, when the channel operates over a common finite field.

Size of Sets with Small Sensitivity: a Generalization of Simon's Lemma

open access: yes, 2016
We study the structure of sets $S\subseteq\{0, 1\}^n$ with small sensitivity. The well-known Simon's lemma says that any $S\subseteq\{0, 1\}^n$ of sensitivity $s$ must be of size at least $2^{n-s}$. This result has been useful for proving lower bounds on

Neutrino emissivities and bulk viscosity in neutral two-flavor quark matter [PDF]

open access: yes, 2016
We study thermodynamic and transport properties for the isotropic color-spin-locking (iso-CSL) phase of two-flavor superconducting quark matter under compact star constraints within a NJL-type chiral quark model.
