UNLABELLED We have compared the use of two (93 and 185 keV) and three (93, 185, and 300 keV) photopeaks for Ga-67 tumor imaging and optimized the placement of each energy window. METHODS The bases for optimization and evaluation were ideal and Bayesian signal-to-noise ratios (SNR) for the detection of spheres embedded in a realistic anthropomorphic digital torso phantom and ideal SNR for the ...
I present Quillen’s proof of the fact that the K-groups KiA where A is the ring of integers in a number field F are finitely generated. This talk was given in the Algebraic K-theory seminar at Michigan during the Winter semester of 2015.
Fever of unknown origin is still a medical challenge. Ga single photon emission computed tomography/computed tomography images are commonly used to evaluate the final diagnosis of fever of unknown origin. We presented a case of fever of unknown origin undergone Ga scintigraphy and an intra-abdominal Ga avid tumor was detected which suspected to be a neoplasm. Further contrast enhanced computed ...
if both reference station (rs) and navigational device in differential global positioning system (dgps) receive signals from the same satellite, rs position components error (rpce) can be used to compensate for navigational device error. this research used hybrid method for rpce prediction which was collected by a low-cost gps receiver. it is a combination of genetic algorithm (ga) computing an...
Cubic GaN has been grown under gallium Ga -rich growth conditions using radio frequency nitrogen plasma molecular beam epitaxy on MgO 001 substrates. Reflection high energy electron diffraction patterns indicate the smoothness of the c-GaN surface and show 2 and even 8 periodicities after the growth at sample temperature Ts 200 °C and 1 1 at higher temperatures. Scanning tunneling microscopy im...
