Halyomorpha halys (brown marmorated stink bug, Hemiptera: Pentatomidae), an invasive insect pest, has established populations in the Willamette Valley of Oregon. Halyomorpha halys is a potential pest of many specialty crops in the Willamette Valley, including hazelnuts (Corylus avellana L.). The objectives of this study were to 1) characterize the...
Hydroacoustic tertiary (T-) waves are seismically generated acoustic waves that propagate
over great distances in the ocean sound channel with little loss in signal strength.
Hydrophone recorded T-waves can provide a lower earthquake detection threshold and an
improved epicenter location accuracy for oceanic earthquakes than land-based seismic
networks. Thus detection...
Alzheimer's disease, a chronic and irreversible form of
dementia, has been recognized as one of the most critical
medical-social-economic problems facing our country. As
Alzheimer's disease and other related dementias progress,

Every government level across the United States had differing responses to COVID-19, and politicians have been the center of attention for their role in COVID policy support or...
The topics in this dissertation are centered around the way that trees respond to environmental stress in the climates where they occur. Though forests across the planet are expected to experience change in local climate due to historic and ongoing anthropogenic greenhouse gas emissions, the effects of climate change will...
Increased automation and computerization have led to new demands and people are quickly transitioning to monitoring automated process and autonomous machines. Human oversight of automated process is important and desired, but people often require aid to navigate information from autonomous sources. An effective way to manage this information is with...
Wheat stripe rust (WSR), also called yellow rust of wheat (Tricitum spp.), causal agent Puccinia striiformis f.sp. tritici (Pst), is a foliar disease of major economic importance on wheat, especially grown in temperate locations. WSR causes major losses of wheat yield, estimated at nearly $ 1 billion per year, and...
