Event rates vs. cross sections at neutrino telescopes
One of the major goals of neutrino astronomy is to explore the otherwise
unknown fluxes and interactions of ultrahigh energy neutrinos. The existing
neutrino telescopes look at three types of events: particle showers, muons, and
taus. In this paper we discuss the dependence of the event rates on the
neutrino nucleon cross-sections as we scale the cross sections, with energy, in
different scenarios beyond the standard model. Our focus will be on the IceCube
detector.Comment: 3 pages, 2 figures; proceedings of the "TeV Particle Astrophysics

Previous Messages Provide the Key to Achieve Shannon Capacity in a Wiretap Channel
We consider a wiretap channel and use previously transmitted messages to
generate a secret key which increases the secrecy capacity. This can be
bootstrapped to increase the secrecy capacity to the Shannon capacity without
using any feedback or extra channel while retaining the strong secrecy of the
wiretap channel.Comment: Accepted for IEEE International Conference on Communications Workshop
