We study an optoelectronic time-delay oscillator that displays high-speed chaotic behavior with a flat, broad power spectrum. The chaotic state coexists with a linearly stable fixed point, which, when subjected to a ...

Michael Pelcovits (1979, p. 303) recently showed that with an unstable foreign excess supply curve, either a futed quota or a buffer stock program with a fixed tariff can be used to stabilize domestic price at a given ...

We report a new nonlinear optical process that occurs in a cloud of cold atoms at low-light-levels when the incident optical fields simultaneously polarize, cool, and spatially-organize the atoms. We observe an extremely ...

Smoking is an expensive habit. Smoking households spend, on average, more than $1000 annually on cigarettes. When a family member quits, in addition to the former smokers improved long term health, families benefit because ...

Applied economists are often interested in studying trends in important economic indicators, such as inequality or poverty, but comparisons over time can be made impossible by changes in data collection methodology. We ...
