Covert Wireless Communication With Artificial Noise Generation
IEEE Transactions on Wireless Communications, 2018 Covert communication conceals the transmission of the message from an attentive adversary. Recent work on the limits of covert communication in additive white Gaussian noise (AWGN) channels has demonstrated that a covert transmitter (Alice) can reliably transmit a maximum of $\mathcal{O}\left(\sqrt{n}\right)$ bits to a covert receiver (Bob) without ...

The Effect of Noise Reduction Measures on the Perception of Railway Noise
, 2015 The A-weighted sound pressure level is a commonly used quantity to assess the effect of noise reduction measures. However, psychoacoustic variables, in particular loudness, are assumed to better explain perceived annoyance.

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.
