Also, in case [gamma] < 0 we have normal dispersion and in case [gamma] > 0 anomalous dispersion.
Third, we plan to demonstrate mid IR frequency combs using crystalline resonator and quantum cascade lasers: Crystalline resonators can due to their anomalous dispersion and large transparency generate low phase noise combs in the mid IR.
Then they used X-ray crystallography, including a technique called molecular replacement with single-wavelength anomalous dispersion, to determine the structure and interaction of the two parts.
To start with, the pulse alters the properties of each section of the pathway so that it exhibits what's known as anomalous dispersion.
Chymosin is many times larger than any molecule whose structure had previously been determined without the use of isomorphous replacement, molecular replacement or anomalous dispersion, and the map demonstrates the potential of maximum-entropy methods in macromolecular structure determination.
The phases for structure determination were obtained using a combination of three experiments: Pt multi wavelength anomalous dispersion (MAD), BR MAD, and Xe single wavelength anomalous dispersion (SAD).
The effect of anomalous dispersion on the wavelengths of the components of light, however, is to modify them.
Employing anomalous dispersion glass, effective in eliminating chromatic aberration, and large-diameter aspherical lenses, the zoom lenses achieve high-resolution imaging from the center of the frame to the outer edges.
The influence of normal and anomalous dispersion on the character of solution is demonstrated by solving system (3) in its linear form (N = M = 0) under a sinusoidal boundary condition for the material initially at rest (see [17] for details).
The company is planning a summer till sampling program designed to increase the sample density where required on the property and to better define the head of the known anomalous dispersion trains.
If [GAMMA] is positive, we have the normal dispersion case, if [GAMMA] is negative, we have the anomalous dispersion case, and if [GAMMA] is equal to zero, we have the dispersionless case.
5 7x optical zoom lens features an advanced apochromatic (APO) lens design employing anomalous dispersion (AD) glass to minimize chromatic aberration at all focal lengths and produce sharp, contrasty images.
