O I S E in amplifiers is now a familiar term. A n y one who has had his favorite radio hour ruined by static knows the effect of an incoherent background of noise.

The average gravitational lens distortion of background galaxy images by foreground galaxies in an independent, non-kinematical measurement of average galaxy mass distribution M(r)/r.

The Universe on Giga parsec scales appears smoother than expected, given the observed persistence of structure on all scales up to 100 Mpc.

We propose and analyze a new class of transmission line codes that dramatically increase the dispersion tolerance and spectral efficiency of dense wavelength-division multiplexing transmission.

We propose a new coverage metric for delay fault tests.

We propose a new coverage metric for delay fault tests.

A mathematical analysis of the bridge polar duplex telegraph circuit, under the condition that the bridge arms are of equal resistance, shows that there is a particular bridge arm resistance which

Open wire circuits recently have been developed for transmitting radio broadcast programs with greater naturalness and over greater distances than heretofore.

A N E W carrier telephone system for open-wire telephone lines has been described recently.

Euclid defines a line as having length but no breadth. Lines in the context of machine vision are the perceptually limiting cases of narrow contrasting strips.
