Cancer Cell Detection with Mask R-CNN

Creator:: Wong, Ryan
Abstract:: Instance segmentation, the classification and localization of objects in an image, is a problem in cellular biophysics due to the physiological relevance of cell morphology. Particularly, cancer cells migrate in tissue space by changing their body shape similarly to how humans extend their limbs to swim through water. Monitoring such...

Music Generation and Evaluation Using R

Creator:: Lanz, Andrea L.
Abstract:: The main goal of this project is to implement an algorithmic music composition procedure and present all procedures and results in a reproducible fashion by creating a web application produced by R. To approach the implementation of the algorithmic composition of music, we start by exploring various models, but ultimately...

Measuring Past Networks of Cultural Transmission: The Haskett Projectile Point

Creator:: Stone, Samantha R.
Abstract:: Advances in technology such as 3D digital scanning and spatial analysis software have provided archaeologists with novel data. Specifically, these methods increase the researcher's ability to measure artifact morphology and past networks of cultural transmission, to potentially track the movement of past peoples and ideas through space and time. This...

Fungal endophytes as source to combat bacterial infections

Creator:: Green, Jaimie R
Abstract:: Endophytes, foliage inhabiting fungi, are an unexplored source of fungal biodiversity and a potential resource for the production of bioactive natural products. In this research, leaf tissues from the species Arbutus menziesii, Rhododendron macrophyllum and the genus, Ilex and Salix were collected for the isolation of endophytic fungi. Fungal extracts...

Abiotic and biotic predictors of coastal giant salamander (Dicamptodon tenebrosus) in headwaters of the Oregon Coast Range

Creator:: Neal, Nathaniel G.
Abstract:: From British Columbia to northern California, coastal giant salamanders (Dicamptodon tenebrosus) are a dominant vertebrate predator in headwater streams. Though widespread, salamander health and abundance levels differ greatly between locations, provoking the question as to what factors may influence this variation and whether habitat features or biotic variables play a...

Monitoring Resistance in Onion Thrips to Insecticides, Lannate® and Exirel®, in the Treasure Valley of Eastern Oregon and Southwestern Idaho

Creator:: Sanchez, Kevin
Abstract:: To evaluate and monitor insecticide resistance in onion thrips Thrips tabaci on onion (Allium cepa), we conducted a study using three field populations in the Treasure Valley of eastern Oregon and southwestern Idaho using the insecticides Lannate (methomyl) and Exirel (cyantraniliprole). To evaluate these two insecticides, biological assays were conducted...

Characterization of a Sporulation-Specific Kinase in Clostridium perfringens

Creator:: Danielson, Bryan
Abstract:: Clostridium perfringens type A isolates produce the spore-specific enterotoxin, CPE, upon sporulation in the gastrointestinal tract of humans and animals. Spo0A is a response regulator representing the major transcription factor for sporulation initiation in C. perfringens. In Bacillus subtilis, a multicomponent phosphorelay involving five histidine kinases (KinA-KinE), the intermediate response...

Genetic variation of Renibacterium salmoninarum genes in infected salmonids

Creator:: Burnett, Jeffrey R.
Abstract:: Renibacterium salmoninarum is the causative agent of bacterial kidney disease in both wild and farmed salmonid species worldwide. The genome of this pathogen has significant synteny to the ubiquitous, soil-dwelling Arthrobacter spp. though it is 1.9 Mb smaller, suggesting that reductive evolution has occurred. Recently, our group finished sequencing and...

Trailing Edge Flap Optimization for an Upper-Surface Blown Aircraft Wing

Creator:: Kelly, Bryan R.
Abstract:: Integrated Distributed Electric Augmented Lift (IDEAL) applies upper surface blowing in a novel way to achieve electric short take-off and landing to meet the growing need for urban air transportation. Additional research on propulsion airframe interaction (PAI) with trailing edge flaps at low Reynolds numbers was necessary to advance the...

Automated annotation of Caenorhabditis mitochondrial genomes and phylogenetic analysis

Creator:: Campbell, Jessica L.
Abstract:: Motivation Relatively little is known about the evolution of mitochondrial genomes between Caenorhabditis species despite decades of research. Both the worldwide search for new nematode species and the effort to increase sequencing speeds require automated tools to quickly characterize and categorize large amounts of data. Results We developed an automated...
