  • Characterization of a Novel Metalloprotease Secreted by the Type II Secretion System in Vibrio cholerae

    Creator:
    Park, Bo R.
    Abstract:
    Vibrio cholerae, a Gram-negative bacterium, is the etiological agent of cholera. V. cholerae shuttles between the human host and the aquatic reservoir, where it associates with marine organisms such as copepods and vertebrate fish. The bacteria use the Type II Secretion System (T2SS) to release proteins that facilitate V. cholerae...

  • 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...

  • Encounters, norms, crowding, management, and behavioral responses of visitors at coastal state parks in Oregon

    Creator:
    Mouw, Wesley J.
    Abstract:
    With the baby boomer cohort retiring and arguably having more time for outdoor recreation, coupled with population increases and government agencies encouraging people to recreate outdoors, areas such as state and national parks will likely continue seeing high visitation. It is imperative, therefore, for outdoor recreation managers and researchers to...

  • Evaluating Methods for Measuring Visitor Perceptions of Ecological Impacts at Wilderness Campsites

    Creator:
    Harris, Richard Lee
    Abstract:
    The objective of this study was to determine whether visitor perceptions of ecological impacts at wilderness campsites could be accurately measured using photographs or written descriptions rather than actual site evaluations. Photographs and written site descriptions of 20 campsites were used to measure perceptions of two forms of campsite impacts...

  • Mechanics Controls Collective Cancer Invasion

    Creator:
    Alobaidi, Amani A.
    Abstract:
    Cancer cell migration in three-dimensional extracellular matrix is a major cause of death for cancer patients. Although extensive studies have elucidated detailed mechanism of single cell 3D invasion and cell-ECM interaction, 3D collective cancer invasion is still poorly understood. 3D collective migration models have unveiled unexpected degrees of diversity and...

  • Multi-scale Investigation of Bidirectional Feedback Mechanism Between Breast Cancer Cells and Extracellular Matrix

    Creator:
    Kim, Jihan
    Abstract:
    Cell migration is fundamental for physiological processes such as immune re-sponses, wound healing and development. It is also a critical characteristic of metastatic cancer cells. An extensive amount of studies have focused on 2D sub-strates in order to understand the mechanism of cancer metastasis. However, much less is known about...

  • Directing Cell Migration via Environmental Anisotropy

    Creator:
    Sheetz, Justin
    Abstract:
    Type I collagen fibers, the connective tissue that makes up the human breast, can be easily manipulated by cells or other outside factors. In previous studies, the alignment of collagen has been associated with the beginning of metastatic cancer, possibly influencing cancerous cells to migrate from the tumor. In this...

  • Multicellular monolayer’s self-organization under external stimuli

    Creator:
    Li, Guanyu
    Abstract:
    Cell signaling under external stimulation is a critical mechanism that governs many biological processes such as cell proliferation, cell migration, and cell apoptosis, etc. For multicellular organisms, the ability to synchronize heterogeneous individual cellular responses through intercellular communication is crucial to maintain normal functionality. However, even though the biological pathways...

  • Sputter Deposition and Characterization of Transparent Conductive Oxide Thin Films and Applications in Photonics

    Creator:
    Bo, Yunfei
    Abstract:
    Transparent conductive oxides (TCOs), combining the optical transparency and electrical conducting properties, have attracted escalating research interests in recent years due to their potential for various photonic applications. The electrical and optical properties, such as carrier concentration, mobility, will strongly affect the performance of TCO-based photonic devices. In this dissertation,...

  • Non-enzymatic electrochemical sensors based on functionalized nanomaterials

    Creator:
    Wu, Bo
    Abstract:
    Unlike other biosensing, electrochemical biosensor has the advantages of robustness, easy miniaturization, excellent detection limits, and capability in handling small analyte volumes. The detection selectivity of the electrochemical biosensors is mainly supported by bioreceptors. However, these receptors always suffer from the performance variation caused by the environment and the thermal-...
