Assessing Petal-cutting bees (Megachile sp.) usage of Clarkia amoena (Onagraceae) petals through the lens of iNaturalist and a Garden Experiment

Creator:: Mead, Mallory
Abstract:: Farewell-to-spring (Clarkia amoena) is native to the Pacific Northwest and commonly found in gardens, due to its aesthetic value and purported benefits to pollinators. Oregon and Washington are home to five subspecies of C. amoena, yet commercially available seed is limited to C. amoena ssp. lindleyi and C. amoena cultivars....

Checking for Noise Model Consistency Between the NANOGrav 12.5- and 15-Year Data Sets

Creator:: Ashby, Andrew
Abstract:: The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) is an international collaboration that seeks to use perturbations in the time of arrivals of pulsar signals to detect gravitational waves in the nanohertz range of frequencies. The 15-year data set will be released as of June 2023. It is a...

Gene expression analysis in feline injection-site sarcoma : differential expression of the ΔNp63 and TAp63 isoforms

Creator:: Dien, Thalia
Abstract:: Background Feline injection-site sarcoma (FISS) is a rare and aggressive tumor associated with vaccines, drug injections, and skin trauma in cats. The understanding of FISS remains limited, posing challenges in its diagnosis, treatment, and prevention. In this study, we analyzed the differential expression of miRNAs and their target genes in...

Aluminum Tolerance of Winter Wheat

Creator:: Sadler, Cameron
Abstract:: Wheat is an important part of a healthy and balanced diet, requiring six servings per day to maintain a recommended 2000 Calorie intake (McRae, 2017). Because of this more land than almost any other kind of cereal is set aside for the purposes of growing wheat. To keep up with...

Computational study of the structure of indium alloys at low temperatures using ab initio methods

Creator:: Shin, Hongsik (Jay)
Abstract:: Crystals are solid materials with periodic and symmetric molecular patterns. The structure of a crystalline solid determines its properties, making it essential to study its structures. From the principle of minimum energy, a crystal will choose a structure with the lowest free energy F = U – TS. At low...

Monitoring Onion Thrips Response to Insecticide Agri-Mek SC in the Treasure Valley of Eastern Oregon and Western Idaho

Creator:: Flores Elizondo, Dennet
Abstract:: Onion thrips (Thrips tabaci) are pests found in onion fields of the Treasure Valley, which is located in Eastern Oregon and Western Idaho. Thrips cause damage to this high value crop by feeding on the onion’s extracellular fluid, making photosynthesis more difficult to occur. The feeding from the thrips can...

Using the Langevin Equation to Verify a Single-Particle Brownian Motion Simulation

Creator:: Snyder, Brendan
Abstract:: Brownian motion is the movement of a particle in a fluid resulting from collisions with surrounding molecules. It has modern applications in simulating fluid dynamics and the motion of proteins in biophysics. Brownian motion simulations generally evolve the initial state by applying Newton’s second law to every particle. These simulations...

Time resolved terahertz spectroscopy of photocarrier dynamics in WSe2

Creator:: Johnson, Nathan
Abstract:: Semiconductors serve an integral role in our technologies today. However, with new advancements in ultra-fast electronics, we are approaching the fundamental speed limits of traditional silicon-based semiconductors. Silicon-based semiconductors typically exhibit photocarrier dynamics in nanosecond timescales. Transition metal dichalcogenides (TMDs) are 2D materials shown to exhibit photocarrier dynamics in picosecond...

Utilization of structure-activity-relationship for predicting chemical toxicity in primary human lung cells

Creator:: Galbreath, Amanda
Abstract:: There is a growing need to establish alternative approaches for assessing hazard from chemical exposure compared to the traditional method of animal testing. Approaches that relate chemical structure to biological activity are gaining acceptance in the field as in silico methods for characterizing and predicting chemical toxicity. In this study,...

Development of a diagnostic assay for Phytophthora ramorum lineage detection

Creator:: Roig-Paul, Mireia
Abstract:: Phytophthora ramorum is the causal agent of Sudden Oak Death (SOD), which is an economically and environmentally important disease causing up to 80% mortality of tanoaks in Pacific Northwest coastal forests (LeBoldus et al., 2022). There are currently four clonal lineages in the United States and Europe, named North America...
