Research Objective:
Determine if disparities in the allocation of lifesaving organs, specifically the kidney and liver, exist between low and non-low socioeconomic status (SES) groups in the US.
Study Design:
A literature review will be conducted to examine anticipated inequalities between patients of different SES. Potential causes of the disparity...
Hepatocellular carcinoma (HCC) is one of the leading causes of cancer death in the United States. Patients with cirrhosis are more likely to develop HCC. More than 80% of HCC patients are found have preexisting cirrhosis. The prevalence of cirrhosis increased from 0.26% to 0.3.% between 1999 to 2010 and...
The enactment of the Patient Protection and Affordable Care Act (ACA) can be considered an important policy intervention in the context of the U.S. health care. The ACA supported non-elderly adults to obtain health insurance coverage. While Medicare provided health insurance to almost all elderly-adults (persons over 65), the ACA...
The purpose of this dissertation was to examine the effects of war stressors and psychosocial factors on negative and positive mental health outcomes among Korean Vietnam War veterans. The sample consisted of 367 male veterans who completed a self-reported survey conducted in 2017 (Mage = 72, SD = 2.66, range...
The overall focus of this thesis is on the distribution of specific lipids and membrane proteins of the external and internal membranes of plant cells, in the context of the roles that those lipids and proteins may play in microbe-plant interactions. The work includes the development of several new tools,...
Multiple-input multiple-output wireless systems promise significant capacity gain
and/or diversity gain over single antenna systems. If channel state information (CSI)
is available at both the transmitter and the receiver, the performance can be further
improved. In this thesis, first, we study binary index feedback problem in beamforming
systems when the...
This thesis describes compensation techniques for cascaded delta-sigma A/D
converters (ADCs) and high-performance switched-capacitor (SC) circuits. Various
correlated-double-sampling (CDS) techniques are presented to reduce the effects of the
nonidealities, such as clock feedthrough, charge injection, opamp input-referred noise and
offset, and finite opamp gain, in SC circuits. A CDS technique...
This dissertation presents a low-power high-resolution delta-sigma ADC. Two new architectural design techniques are proposed to reduce the power dissipation of the ADC. Compared to the conventional active adder, the direct charge transfer (DCT) adder greatly saves power by keeping the feedback factor of the active adder unity. However, the...
The purpose of this research is to hydraulically characterize an engineered wetland in Albany, Oregon. The wetland receives treated wastewater from both Albany Millersburg Water Reclamation Facility (AMWRF) and ATI Wah Chang. AMWRF's water is municipal waste water. ATI Wah Chang's water comes from its nearby metal processing plant. The...
