  • Conservation of arthropod natural enemies in broccoli with relay strip-cropping

    Creator:
    McGrath, Daniel M. (Daniel Morton)
    Abstract:
    Relay strip-cropping combines two vegetation management tactics, under-sowing and strip-management. In this study conducted from 1994 though 1997, a cover crop seed-mixture containing oats (Avena sativa L. var. "Monida"), common vetch (Vicia sativa L.), red clover (Trifolium pratense L.), annual ryegrass (Lolium multflorum Lam.), and buckwheat (Fagopyrum esculentum Moench) was...

  • Assessing the role of reactive metal species in soil organic matter cycling using chemical imaging

    Creator:
    Keiluweit, Marco
    Abstract:
    Intimate associations with reactive metal species permanently protect soil organic matter (SOM) from microbial access and oxidation, contributing to the build-up of organic carbon (C) stocks in soils. It is increasingly recognized, however, that such associations can be reversible and that reactive metal species might even facilitate the oxidation of...

  • Non-viral Vectors for Ocular Gene Delivery

    Creator:
    Herrera-Barerra, Marco, F.
    Abstract:
    Nucleic acid therapeutics has cemented itself as one of the most efficacious and robust avenues for treatment of a wide range of diseases from vaccine development to treatment of liver, retina, cancer applications. Non-viral mediated gene delivery using lipid-based nanoparticle (LNP) carriers has proven its compatibility with addressing unexpected, fast...

  • The relationship between income and food insecurity : the role of social support in rural and urban Oregonians

    Creator:
    De Marco, Molly M.
    Abstract:
    Millions of U.S. households experienced hunger in 2005 and millions more experienced food insecurity. Previous research indicates that low-wage work and little social support contribute to food insecurity. Research also suggests that individuals cope by finding alternate food sources and drawing on social support. Further, researchers have found that rural...

  • Design techniques for wideband low-power Delta-Sigma analog-to-digital converters

    Creator:
    Wang, Yan
    Abstract:
    Delta-Sigma (ΔΣ) analog-to-digital converters (ADCs) are traditionally used in high quality audio systems, instrumentation and measurement (I&M) and biomedical devices. With the continued downscaling of CMOS technology, they are becoming popular in wideband applications such as wireless and wired communication systems,high-definition television and radar systems. There are two general realizations...

  • Network Analysis and Change-point Detection

    Creator:
    Xu, Jiarui
    Abstract:
    Analysis of observations on sequential events over time is common in real life. Sequential measurements over time describing the behavior of systems are usually called time series data, which have been collected in a wide range of disciplines. Over the years there have been multiple research areas in studying stochastic...

  • Graphite intercalation compounds containing fluoroanions

    Creator:
    Katinonkul, Watcharee
    Abstract:
    New chemical synthesis strategies have been investigated for the preparation of acceptor-type graphite intercalation compounds (GIC's) with fluoroanions in order to obtain new materials and to develop a better understanding of the synthetic approaches and properties of the products. New GIC's containing borate chelate anion such as bis(oxalato)borate, CxB[OC(O)C(O)O]₂•δF, are...

  • Hybrid Multiscale Methods with Applications to Semiconductors, Porous Media, and Materials Science

    Creator:
    Costa, Timothy B.
    Abstract:
    In this work we consider two multiscale applications with tremendous computational complexity at the lower scale. First, we examine a model for charge transport in semicon- ductor structures with heterojunction interfaces. Due to the complex physical phenomena at the interface, the model at the design scale is unable to adequately...

  • Agile Bipedal Locomotion via Hierarchical Control by Incorporating Physical Principles, Learning, and Optimization

    Creator:
    Green, Kevin
    Abstract:
    Robotic Bipedal locomotion holds the potential for efficient, robust traversal of difficult terrain. The difficulty lies in the dynamics of locomotion which complicate control and motion planning. Bipedal locomotion dynamics are dimensionally large problems, extremely nonlinear, and operate on the limits of actuator capabilities, which limit the performance of generic...

  • Computational Approaches for Understanding Combinatorial Gene Regulation

    Creator:
    Ansariola, Mitra
    Abstract:
    Gene regulation is a complex mechanism that controls the spatial and temporal expression of genes in a living cell. My dissertation studies focus on two problems. First, tissue-specific gene expression prediction from DNA sequence and chromatin state, and second, the accurate discovery of small over-represented regulatory circuits in gene regulatory...
