Long term evolution of planetary systems with a terrestrial planet and a giant planet

open access: yes, 2016
We study the long term orbital evolution of a terrestrial planet under the gravitational perturbations of a giant planet. In particular, we are interested in situations where the two planets are in the same plane and are relatively close. We examine both

The time behavior and spectra of relaxation oscillations in a high-gain laser [PDF]

open access: yes, 1972
It is found that under appropriate conditions the high-gain 3.51-μ xenon laser may exhibit relaxation oscillations in the frequency range of 1 to 10 MHz. Experimental investigations have been conducted in both the time and frequency domains.
