Radiation therapy is a sophisticated complex process. Systematic methods are needed to quantitatively evaluate the quality of a complex process and hence radiation therapy treatments. An ideal result for a complex process must be established to determine if the complex process is completed acceptably. For radiation therapy, this can be...
Radiation therapy treatment planning and optimization requires accurate, precise,
and fast computation of absorbed dose to all critical and target volumes in a patient. A
new method for speeding up the computational costs of Monte Carlo dose calculations is
described that employs a hybrid classical-quantum computing architecture.
Representative results are...
We present the results of our experiments designed to extend the clinical applications of commercially available Optically Stimulated Luminescence (OSL) Dosimeters. Our initial experiments demonstrate the linear response of the OSL dosimeters for doses under 200 cGy and the non-linear response of the device after 200 cGy. Our experiments show...
A detailed biographical sketch of Ralph W. Spitzer (b. 1918), a graduate student of Linus Pauling's and promising academic who joined the Oregon State College chemistry department in 1946. Promoted to Assistant Professor in 1947, Spitzer was nonetheless fired from the OSC faculty in 1949 by President August L. Strand,...
The purpose of this study is aimed at developing a simple bioeconomic model of the Namibian rock lobster fishery, with the main objective being to incorporate economics into fisheries management in order to estimate the potential economic benefits that could accrue to the fishery given efficient management. The complex nature...
Mammalian cysteine dioxygenase (CDO) is a mononuclear non-heme iron protein that catalyzes 2 the conversion of cysteine (Cys) to cysteine sulfinic acid (CSA) by an unclarified mechanism. 3 One structural study revealed a Cys-persulfenate (or Cys-persulfenic acid) formed in the active 4 site, but quantum mechanical calculations have been used...

Deoxyribonucleoside triphosphate pools in mammalian mitochondria are highly
asymmetric, and this asymmetry probably contributes toward the elevated
mutation rate for the mitochondrial genome as compared with the nuclear
genome. To understand this asymmetry, we must identify pathways for synthesis
and accumulation of dNTPs within mitochondria. We have identified
ribonucleotide reductase...
