In this dissertation, I present the results from three studies: (1) a phylogeny of Tenebrionoidea (Coleoptera) inferred from a seven-gene dataset derived from PCR and Sanger sequencing; (2) a phylogeny of Tenebrionidae, the largest family in Tenebrionoidea, inferred from a four-gene dataset also derived from PCR and Sanger sequencing; (3)...
Adults with severe and persistent mental illness (SPMI) are overrepresented in the homeless population, and Oregon’s homeless population has expanded in recent years. In the 1950s, the mentally ill were moved out of the state hospitals and into the community. However, due to a lack of support services in the...
There are numerous references in the literature concerning
the use of various Arctostaphylos species as medicinal plants.
One of the species, A. uva-ursi, was listed in the United States
official compendia from 1820 until 1946 as a urinary antiseptic.
Many species indigenous to the Pacific Northwest were employed
by the...
A pharmacognostic study was made of the root of Heracleum
mantegazzianum, an umbelliferous species which is of value as a
source of natural coumarins.
Three groups of seeds were tested to determine the presence
of a germination requirement for moist cold and the possible value
of gibberellic acid in obviating...
Natural Language Comprehension is a challenging domain of Natural Language Processing. To improve a model’s language comprehension/understanding, one approach would be to enrich the structure of the model to enhance its capability in learning the latent rules of the language.
In this dissertation, we will first introduce several deep models...
We consider three problems on simplicial complexes: the Optimal Bounded Chain Problem, the Optimal Homologous Chain Problem, and 2-Dim-Bounded-Surface. The Optimal Bounded Chain Problem asks to find the minimum weight d-chain in a simplicial complex K bounded by a given (d−1)-chain, if such a d-chain exists. The Optimal Homologous Chain...
The pyrrolizidine alkaloids (PAs) and ergot alkaloids are known natural toxicants found in livestock forage. These alkaloids contribute to large economic losses in livestock throughout the world. An understanding of the mechanisms of toxicity and development of better diagnostic tools for better management practices was investigated. Variability exists in the...
The 134-year old Frantz-Dunn House in Hoskins, Oregon is an intact, well-preserved example of rural Gothic architecture in the Willamette Valley. The old farmstead sits on a former Civil War Fort site and represents a link in the history of the region to the larger patterns of expansion in America...
