PMID: 17282698
Conf Proc IEEE Eng Med Biol Soc. 2005;2005:2316-8. doi: 10.1109/IEMBS.2005.1616929.

A two-step method to determine the seed parameters for the planning of peripheral intravascular brachytherapy, which took the actual vessel geometry into consideration, was developed. Firstly, the characteristics of the vessel geometry was obtained by using active navigation; Then...

Reflectance spectra in the visible and near-infrared wavelength region provide a rapid and inexpensive means for determining the mineralogy of samples and obtaining information on chemical composition. Hydrocarbon microseepage theory establishes a cause-and-effect relation between oil and gas reservoirs...

Multibeam coupling in photorefractive SBN:Ce.

Optics letters

Ma J, Liu L, Wu S, Wang Z, Xu L, Shu B.
PMID: 19746112
Opt Lett. 1988 Nov 01;13(11):1020-2. doi: 10.1364/ol.13.001020.

Theoretical and experimental results are presented for simultaneous multibeam coupling in photorefractive SBN:Ce. Within a single crystal, multiple signals are amplified through a coupling process that employs a single pump. The coupling gain of each signal results from coupling...
