  • Total synthesis of phorboxazole A

    Creator:
    Lee, Tae Hee
    Abstract:
    The total synthesis of a highly potent cytotoxic marine natural product, phorboxazole A, is described. Both a palladium(II)-mediated and a palladium(II)-catalyzed intramolecular alkoxycarbonylation were used as key steps for the preparation of the two cis-2,6-disubstituted tetrahydropyran rings (C22-C26 and C11-C15) of phorboxazole A. The synthesis used a convergent approach involving...

  • Generation and manipulation of THz waves

    Creator:
    Amer, Naaman
    Abstract:
    In this thesis I studied several THz components that can be used for potential THz technology. THz waves were generated in nonlinear medium via optical rectification of femtosecond optical pulses. Utilizing the phase matching condition between the optical and THz waves in a ZnTe crystal, single-cycle broad-band THz pulses were...

  • Biology of chlamydospores of Phytophthora ramorum

    Creator:
    Smith, Aaron Lee
    Abstract:
    The chlamydospore is a survival spore produced by 35 of the 75 described species of Phytophthora. Phytophthora ramorum Werres, de Cock & Man in't Veld, the causal agent of Sudden Oak Death (SOD), produces abundant chlamydospores in artificial culture and plant tissue. The chlamydospore is likely the most important survival...

  • Multi-dimensional parametric estimation: two-dimensional sharpening by predictive bandwidth extrapolation and fast algorithms for three dimensional autoregressive estimation

    Creator:
    Liew, Ji Seok
    Abstract:
    Achieving sharpened (enhanced detail) features of a multi-dimensional data source using the linear prediction (LP) bandwidth extrapolation (BWE) technique in the transform domain is the main objective of this research. The evolution of sensor technology has provided acquisition scenarios in which the data format is inherently multi-dimensional, including hyperspectral imaging...

  • Low-power design techniques for low-voltage analog-to-digital converters

    Creator:
    Kim, Min Gyu
    Abstract:
    The demand for portable electronic systems and the continued down-scaling of device dimensions resulted in rapid improvement in the performance of integrated systems. Several low-voltage design techniques have been proposed to operate analog circuits with sub-1V supply. However, these techniques require higher power consumption to achieve large dynamic range while...

  • Developing a system of mutagenesis in Francisella tularensis LVS

    Creator:
    Flax, Lindsay A.
    Abstract:
    Francisella tularensis is a gram-negative facultative intracellular coccobacillus that primarily infects macrophages. The causative agent of tularemia, this bacterium is considered among the most infectious organisms known, requiring fewer than ten organisms to cause disease. Although ubiquitous in nature, transmission to humans is rare but can occur via insect bites,...

  • Distribution of Ceratomyxa shasta (Myxozoa) and habitat preference of the polychaete host, Manayunkia speciosa in the Klamath River

    Creator:
    Stocking, Richard W.
    Abstract:
    Ceratomyxa shasta is a myxozoan parasite of salmonids and requires the freshwater polychaete, Manayunkia speciosa to complete its life cycle. The parasite’s distribution is currently limited to the Pacific Northwest region of North America and has been reported to cause substantial losses of both wild and hatchery salmonids. The spatial...

  • Red light ladies : settlement patterns and material culture on the frontier

    Creator:
    Simmons-Rogers, Alexandra L.
    Abstract:
    Red Light Ladies presents a perspective on prostitution in North America, within the context of the western mining frontier. A biographical profile of the frontier prostitutor is presented, along with an archaeological model of settlement patterns and material culture. Settlement patterns and demographic changes in the prostitutor population are hypothetically...

  • Identification of an aerotaxis transducer in Vibrio cholerae

    Creator:
    Boin, Markus A.
    Abstract:
    The ability to move towards favorable environmental conditions, called chemotaxis, is common among motile bacteria. In particular aerotaxis has been extensively studied in Escherichia coli. Three putative aer gene homologs were identified in the V. cholerae genome designated VCAer-1 (VC0512) VCAer-2 (VCA0658), and VCAer-3 (VCA0988). Deletion analyses indicated that only...

  • Characterization of vaccinia virus A12L protein : its proteolysis and functional analyses in virus replication

    Creator:
    Yang, Su Jung
    Abstract:
    In order to produce infectious virus progeny, vaccinia virus (VV) undergoes morphogenic proteolysis to regulate the structural rearrangements of virus particles. Several of the major structural precursor proteins of VV are cleaved at a conserved Ala-Gly-X (where X is any amino acid) motif by the VV I7L core protein proteinase...
