Bright Lights, Single Molecules

Telerehabilitation robotics: bright lights, big future?

The potential for remote diagnosis and treatment over the Internet using robotics is now a reality. The state of the art is exemplified by several Internet applications, and we explore the current trends in developing new systems. We review the technical challenges that lie ahead, along with some potential solutions. Some promising results for a new bilateral system involving two InMotion2 robo...

How Dark Is Dark? Bright Lights, Big City, Racial Profiling

Grogger and Ridgeway (2006) develop a feasible test for racial profiling "behind a veil of darkness" that exploits the exogenous variability in the visibility of driver race caused by the daylight savings time shift. The idea is that police are less able to use race as a criteria in traffic stops when it is dark, so differences in stop rates for African-Americans between dark and light (while c...

Bright lights in dark places: physician recognition of alcoholism.

Behavioral confirmation of the "silent period" during adaptation to bright lights.

The “silent period” is an interval of time following the onset of an intense background during which there is absolute refractoriness to incremental light stimuli. The phenomenon has been reported to occur at all levels of retinal processing in the skate (Dowling and Ripps, 1970, 1971, 1972; Green, Dowling, Siegel and Ripps, 1975), in the ERG of several other elasmobranchs (Hamasaki and Bridges...

Single-mode source of bright squeezed vacuum

Bright squeezed vacuum (BSV) can be obtained at the output of a high-gain traveling-wave optical parametric amplifier with the vacuum at the input. Without any special efforts, it is multimode both spatially and temporally. This means it comes as not Fourier-limited pulses and not diffractionlimited beams. At the same time, what theory describes well and what is required for most applications i...
