  • Computer Vision Model Selection For Real-Time Tracking of Apples

    Creator:
    Bloch, Peter J.
    Abstract:
    This paper presents a method of implementing real-time apple detection for closed-loop control to approach apples for grabbing. The approach is to train two known real-time object detection networks–the Faster R-CNN and YOLOv5–on a novel dataset to verify that it is possible to achieve maximum average precision (mAP) above 50\%...

  • Hi-C genome assembly of the ectomycorrhizal fungus Rhizopogon salebrosus

    Creator:
    Har, Skyler
    Abstract:
    Rhizopogon salebrosus is an abundant ectomycorrhizal fungus common throughout Western North America that forms mutualistic partnerships with Pinus species. Studied for its systematics, use in sapling nurseries, post-fire seedling establishment, and unique evolutionary history, R. salebrosus holds many secrets within its genome. This thesis aims to characterize the mating system,...

  • Molecular origins of peptide entrapment within polyethylene oxide brush layers

    Creator:
    Lampi, Marsha C.
    Abstract:
    Effective surface coatings for tissue-contacting medical devices should prevent both biofilm formation and infection. One method to achieve this aim is protein repellant polyethylene oxide (PEO) brush coatings loaded with antimicrobials. Previous research has demonstrated that the antimicrobial nisin adsorbs to PEO brush layers in multi-layer amounts and suggests that...

  • Machine Learning and Optimization Applications in Agriculture

    Creator:
    Molotkov, Alexander
    Abstract:
    The ever-increasing global population presents looming problems for the field of agriculture. Global food demand will, at some point, increase to the point where there is not enough crop-ready land to keep up. This creates an additional incentive, other than economics, for growers to increase their yield-per-acre and make sure...

  • Characterization and application of PEO-containing triblock copolymer surfactants

    Creator:
    Snider, Joshua L.
    Abstract:
    The action of pendant, polyethylene oxide (PEO) brush layers as nonfouling coatings for biomedical materials is well understood. However progress toward clinical application of stable, high density PEO coatings has historically been impeded by the lack of cost effective, noninvasive methods for their preparation. Triblock polymers featuring a hydrophobic, polypropylene...

  • Synthesis of gold nanoparticle surfactants and their self-assembly at oil-water interfaces

    Creator:
    Truong, Mitchell
    Abstract:
    Amphiphilic gold nanoparticle surfactants can self-assemble at oil-water interfaces to form stable Pickering emulsions. These nanoparticle surfactants have previously been synthesized by functionalizing gold nanoparticles with thiol terminated polyethylene glycol (PEG-thiol), and subsequently with an alkane-thiol. It is necessary to improve the bio-compatibility of the nanoparticles if they are to...

  • Functionalization of Surfaces with Nisin in a Polyethylene Oxide Brush Layer

    Creator:
    Ryder, Matthew P.
    Abstract:
    Infections in hospitals account for over 100,000 deaths per year. These infections occur at the hospital from complications following bacterial adhesion to intravenous catheters, coronary stents and other implanted devices. Another common problem is protein adsorption to the surface of the device and subsequent blood clotting. Methods for combating these...

  • Investigation of Glacier Dynamics During the Last Glacial Maximum at Tioga Pass, Yosemite National Park

    Creator:
    Laub, Alexander G.
    Abstract:
    Previous investigations of glacier dynamics at Tioga Pass during the Last Glacial Maximum (LGM) have produced different conclusions. A map of the LGM ice extent and flow direction (Alpha et al., 1987) illustrates a south-to-north direction of ice flow across the pass with little evidence to support this inference. Since...

  • Examining the Human Relevance of a New Mouse Model of ALS and Observations on the Incidence in Human Populations

    Creator:
    Winkenbach, Lindsay
    Abstract:
    Amyotrophic Lateral Sclerosis (ALS) is a relatively rare neurodegenerative disorder that is fatal 2-4 years after the onset of the disease. Population studies are being done in order to help reveal candidates for further studies of disease etiology, disease progression, as well as to further understand racial and ethnic variations....

  • Surfactant Effects on Adsorption of Recombinant Factor VIII (rFVIII) at the Air-Water Interface

    Creator:
    Gray, Warren D.
    Abstract:
    The primary goal was to characterize the adsorption of a recombinant therapeutic protein in the presence of selected surfactant species at the air-water interface. For this purpose, dynamic interfacial tensiometry was used to determine the surface tension kinetics exhibited by protein solutions containing either Tween 80 or the poly[ethylene oxide]-...
