In the field of nuclear medicine, single photon emission tomography and positron emission tomography are the two most common techniques in molecular imaging, but the available radioactive tracers have been limited either by energy range or difficulties in production and delivery. Thus, the use of a Compton camera, which features gamma-ray imaging of(More)
A clock and data recovery circuit is a key element in communication systems for realizing high speed signal transfers. In passive optical transmission systems, a data recovery circuit for burst data is indispensable. A burst-mode clock and data recovery circuit using gated VCOs has been reported. We have proposed data recovery circuits for a continuous bit(More)
The optimum conditions for the extractive-spectrophotometric determination of trace iron(II) with di-2-pyridylmethanone 2-(5-nitro)pyridylhydrazone have been established. Iron(II) reacts with this reagent at pH 2.0-7.5 to form an uncharged 1:2 (metal-to-ligand) complex, which can be extracted with toluene. Beer's law is obeyed over the range up to 0.84(More)
