Abstract: An experimental seven digit pulse code modulation (PCM) system has been built for the ... A beam coding tube converts the signal to seven parallel digits of a binary Gray code at a 10 mc ...

Abstract: A novel modulation format is proposed for time-hopping pulse ... particular TH code, selected by log 2 M-bit data, modulates the basic pulses (i.e., determines the location of the pulses), ...

An international team of astronomers reports the discovery of a new ultracompact binary of the AM CVn type exhibiting ...

This is a potentially valuable modeling study on sequence generation in the hippocampus in a variety of behavioral contexts. While the scope of the model is ambitious, its presentation is incomplete ...

The derived masses and radii of the components are consistent with the empirical mass-radius relationship established recently for lower main sequence stars in binary systems; in particular we find ...

Chemically inducible gene expression systems have been an integral part of the advanced synthetic genetic circuit design and are employed for precise dynamic control over genetically engineered traits ...
