Quantum mechanics. Mechanically detecting and avoiding the quantum fluctuations of a microwave field.
Quantum fluctuations of the light field used for continuous position detection produce stochastic back-action forces and ultimately limit the sensitivity. To overcome this limit, the back-action forces can be avoided by giving up complete knowledge of the motion, and these types of measurements are called "back-action evading" or "quantum nondemolition" detection. We present continuous two-tone...
متن کاملChronic urticaria merits serum vitamin D evaluation and supplementation; a randomized case control study
BACKGROUND Several studies suggest that Vitamin D (Vit-D3) supplementation reduces Chronic Urticaria (CU) symptoms. OBJECTIVES Evaluation of serum 25-hydroxyvitamin-D (25 (OH)2D) level and assessment of therapeutic effect of VitD3in CU patients. METHODS 192 subjects were stratified according to the baseline 25(OH)2D levels and subsequently randomized into three subgroups to receive Vit-D3 a...
متن کاملStress wave attenuation in shock-damaged rock
The velocity and attenuation of ultrasonic stress waves in gabbroic rock samples (San Marcos, California) subjected to shock loading in the 2 GPa range were studied. From P wave velocity measurements we determined the damage parameter Dp and crack density e of the samples and related these to the attenuation coefficient (quality factor) under dynamic strains of 2 x 10 -? and at a frequency of 2...
متن کاملInteraural correlation and the binaural summation of loudness.
The effect of interaural correlation (rho) on the loudness for noisebands was measured using a loudness-matching task in naive listeners. The task involved a sequence of loudness comparisons for which the intensity of one stimulus in a given comparison was varied using a one-up-one-down adaptive rule. The task provided an estimate of the level difference (in decibels) for which two stimulus con...
متن کاملMicrowave Spectroscopy in Oxford: The Early Years Remarks on the Occasion of Receiving the 1983 ISMAR Award
The first measurements of spectra at microwave frequencies using modern techniques were made before the end of World War II. The reason for this was that the frequency of 2k GHz (a wavelength of 12.5 mm; known as "K-band") had been picked by the Radiation Laboratory at M.I.T. for a precision radar system. Unfortunately, it turned out that this coincided with the region at which attenuation in t...
