  • Analyses of noncanonical DNA structures

    Creator:
    Khuu, Patricia A.
    Abstract:
    The structural polymorphic nature of DNA has been long been recognized since the model of the right-handed B-DNA duplex proposed by James Watson and Francis Crick was accepted. Its malleability is thought to be critical in protein recognition and manipulation. In particular, it can form Holliday junctions, four-way DNA structural...

  • Dynamic response of an offshore structure to measured and simulated stochastic wave forces

    Creator:
    Grecco, Michael G.
    Abstract:
    The dynamic response of an offshore structure to measured and simulated stochastic wave forces is investigated. The theoretical nondeterministic analysis is performed in the frequency domain for a two-dimensional model. The ocean wave system is assumed to be a zero mean, stationary, ergodic Gaussian process described by a one-dimensional wave...

  • Syntheses and structures of new inorganic borates

    Creator:
    Sun, Hongxing
    Abstract:
    Several new solid-state inorganic borates have been prepared and characterized. Single crystals of the simple orthoborate ScB0₃ were grown and its structure was determined by single-crystal X-ray methods. The new borates Li₃Sc(B0₃)₂, LaSc₃(B0₃)₄, NdSc₃(B0₃)₄, SrNaB0₃, and Li4Ln4MB90₂₃ (Ln = Y, Er, and Gd; M = Al and Ga) were identified...

  • The analysis and prediction of DNA structure

    Creator:
    Basham, Beth E.
    Abstract:
    As genome sequencing projects begin to come to completion, the challenge becomes one of determining how to understand the information contained within the DNA. DNA is a polymorphic macromolecule; the A- B- and Z-DNA conformations have been observed by a variety of physical techniques. The magnitude of the energetic differences...

  • View based, global design of access structures for relational databases

    Creator:
    Gündem, Taflan İmre
    Abstract:
    In this dissertation we consider the problem of automating the design of access structures for relational database systems. The main considerations are effective and rigorous utilization of the users' usage patterns, global treatment of the whole design and utilizing most of the commonly known access structures. We represent the usage...

  • The effect of cytosine methylation on DNA structure

    Creator:
    Vargason, Jeffrey M.
    Abstract:
    DNA methylation is common in prokaryotes and eukaryotes and has been implicated in various biological roles including gene silencing, X-chromosome inactivation, and genomic imprinting. 5-methylcytosine the "fifth base" of the genetic code comprises 1-3% of the human genome and is primarily found on cytosines within the context of the CpG...

  • Vortex structures and microfronts

    Creator:
    Gerz, Thomas, Howell, Jim, and Mahrt, Larry
    Abstract:
    This study addresses the relationship between thermal microfronts and coherent vortex structures in homogeneous turbulence. The turbulence is created by mean shear in a weakly stratified flow. The data set is generated by direct numerical simulation providing highly resolved instantaneous three‐dimensional fields of fluctuating velocity and temperature (1603 data points...

  • Nucleoprotein structure of adenovirus

    Creator:
    Corden, Jeffry Lynn
    Abstract:
    The structure of the nucleoprotein core of adenovirus has been investigated. Using a combination of biophysical techniques and nuclease digestion I have determined that the adenovirus core, as isolated with pyridine, shares several physical properties with cellular chromatin. The most notable difference is the lack of a nucleosome repeat in...

  • Structure of offshore flow

    Creator:
    Vickers, Dean, Mahrt, L., Sun, Jielun, and Crawford, Tim
    Abstract:
    The horizontal and vertical structure of the mean flow and turbulent fluxes are examined using aircraft observations taken near a barrier island on the east coast of the United States during offshore flow periods. The spatial structure is strongly influenced by the surface roughness and surface temperature discontinuities at the...

  • The structure of E6

    Creator:
    Wangberg, Aaron D.
    Abstract:
    A fundamental question related to any Lie algebra is to know its subalgebras. This is particularly true in the case of E6, an algebra which seems just large enough to contain the algebras which describe the fundamental forces in the Standard Model of particle physics. In this situation, the question...
