Models for gramicidin channels
To the Editor: In several recent papers, NMR results for gramicidin A have been compared with predictions based on various models for a right-handed channel. In particular, 2H quadrupolar splittings (Hing et al., 1990a,b; Prosser et al., 1991) or '5N chemical shifts (Chiu et al., 1991) from solid-state NMR spectra of labeled gramicidin A in oriented ...

A Model for Adversarial Wiretap Channels
In wiretap model of secure communication the goal is to provide (asymptotic) perfect secrecy and reliable communication over a noisy channel that is eavesdropped by an adversary with unlimited computational power. This goal is achieved by taking advantage of the channel noise and without requiring a shared key.
