Telomerase is a special reverse transcriptase that extends the linear chromosome termini in eukaryotes. Telomerase is also a unique ribonucleoprotein complex which is composed of the protein component called Telomerase Reverse Transcriptase (TERT) and a telomerase RNA component (TR). The enzyme from most vertebrate species is able to utilize a short template sequence within TR to synthesize a long stretch of telomeric DNA, an ability termed "repeat addition processivity". By using human telomerase reconstituted both in vitro (Rabbit Reticulocyte Lysate) and in vivo (293FT cells), I have demonstrated that a conserved motif in the reverse transcriptase domain of the telomerase …

Contemporary theories of trauma identify the creation of a coherent trauma narrative and therapeutic exposure to trauma memories as potential recovery mechanisms. These factors are often inherent to the disclosure process, resulting in a parallel theoretical framework for experimental research that conceptualizes disclosure as a therapeutic intervention. The present investigation examined the moderational impact of disclosure following trauma on the link between trauma severity and symptoms of Posttraumatic Stress Disorder (PTSD). Disclosure status (discloser or nondiscloser), highest extent of disclosure, and length of delay to first disclosure were tested in a series of moderated regression models among a sample of …

This thesis examines the modeling, analysis, and control system design issues for scramjet powered hypersonic vehicles. A nonlinear three degrees of freedom longitudinal model which includes aero-propulsion-elasticity effects was used for all analysis. This model is based upon classical compressible flow and Euler-Bernouli structural concepts. Higher fidelity computational fluid dynamics and finite elementmethods are needed formore precise intermediate and final evaluations. The methods presented within this thesis were shown to be useful for guiding initial control relevant design. The model was used to examine the vehicles static and dynamic characteristics over the vehicles trimmable region. The vehicle has significant longitudinal …

Since scholars first turned their attention to the subject some eighty years ago, one major area of contention in the study of Anglo-Saxon wills has been the function of the written will within Anglo-Saxon culture. Verbal agreements, formalized through oral ceremonies and symbolic actions, were recognized as legally binding; however, many of these agreements were also recorded in writing. Many scholars argue that the written document was superfluous;oral ceremonies were written down only in the case of memory failure and the documents themselves had no real performative function. Others see the existence of the written will to be evidence of …

"Globesity," as defined by the World Health Organization, describes obesity as a pandemic affecting at least 400 million people worldwide. The prevalence of obesity is higher among women than men; and in non-Hispanic black and Hispanic populations. Obesity has been significantly associated with increased all-cause mortality, and mortality from cardiovascular disease, obesity-related cancers, diabetes and kidney disease. Current strategies to curb obesity rates often use an ecological approach, suggesting three main factors: biological, behavioral, and environmental. This approach was used to develop four studies of obesity. The first study assessed dietary quality, using the Healthy Eating Index (HEI)-2005, among premenopausal …

Prognostics and health management (PHM) is a method that permits the reliability of a system to be evaluated in its actual application conditions. This work involved developing a robust system to determine the advent of failure. Using the data from the PHM experiment, a model was developed to estimate the prognostic features and build a condition based system based on measured prognostics. To enable prognostics, a framework was developed to extract load parameters required for damage assessment from irregular time-load data. As a part of the methodology, a database engine was built to maintain and monitor the experimental data. This …

To establish reliable wireless communication links it is critical to devise schemes to mitigate the effects of the fading channel. In this regard, this dissertation analyzes two types of systems: point-to-point, and multiuser systems. For point-to-point systems with multiple antennas, switch and stay diversity combining offers a substantial complexity reduction for a modest loss in performance as compared to systems that implement selection diversity. For the first time, the design and performance of space-time coded multiple antenna systems that employ switch and stay combining at the receiver is considered. Novel switching algorithms are proposed and upper bounds on the pairwise …

The music of Johann Sebastian Bach has long been used for keyboard percussion pedagogy and performance. The cello suites (BWV 1007-1012), in particular, are popular choices for marimbists. As with many transcriptions for marimba, performers are challenged to transfer Bach's musical genius onto an instrument whose timbre, range, mode of execution and acoustic properties are distinctly different from the original. To date, there is no concise and relevant edition of the suites for study and performance at the marimba. The edition contained herein solves most, if not all, of the problems normally confronted by marimbists. In addition to synthesizing the …

Many methods have been proposed to estimate power system small signal stability, for either analysis or control, through identification of modal frequencies and their damping levels. Generally, estimation methods have been employed to assess small signal stability from collected field measurements. However, the challenge to using these methods in assessing field measurements is their ability to accurately estimate stability in the presence of noise. In this thesis a new method is developed which estimates the modal content of simulated and actual field measurements using orthogonal polynomials and the results are compared to other commonly used estimators. This new method estimates …

The existing compact models can reproduce the characteristics of MOSFETs in the temperature range of -40oC to 125oC. Some applications require circuits to operate over a wide temperature range consisting of temperatures below the specified range of existing compact models, requiring wide temperature range compact models for the design of such circuits. In order to develop wide temperature range compact models, fourteen different geometries of n-channel and p-channel MOSFETs manufactured in a 0.18μm mixed-signal process were electrically characterized over a temperature range of 40 K to 298 K. Electrical characterization included ID-VG and ID-VD under different drain, body and gate …

The fields of pattern recognition and machine learning are on a fundamental quest to design systems that can learn the way humans do. One important aspect of human intelligence that has so far not been given sufficient attention is the capability of humans to express when they are certain about a decision, or when they are not. Machine learning techniques today are not yet fully equipped to be trusted with this critical task. This work seeks to address this fundamental knowledge gap.

The global transport and deposition of anthropogenic nitrogen (N) to downwind ecosystems are significant and continue to increase. Indeed, atmospheric deposition can be a significant source of N to many watersheds, including those in remote, unpopulated areas. Bacterial denitrification in lake sediments may ameliorate the effects of N loading by converting nitrate (NO3-) to N2 gas. Denitrification also produces nitrous oxide (N2O), a potent greenhouse gas. The ecological effects of atmospheric N inputs in terrestrial ecosystems and the pelagic zone of lakes have been well documented; however, similar research in lake sediments is lacking. This project investigates the effects N …

The bony pelvis is a pivotal component of the locomotor system, as it links the hindlimb with the trunk and serves as anchorage for the primary propulsive musculature. Its shape is therefore expected to be adapted to the biomechanical demands of habitual locomotor behavior. However, because the relationship between locomotor mechanics and pelvic morphology is not well understood, the adaptive significance of particular pelvic traits and overall pelvic shape remains unclear. This study used an integrative, dual approach to elucidate the relationship between form and function in the primate pelvis. A biomechanical cylinder model of pelvic stress resistance was tested …

The Resource Description Framework (RDF) is a specification that aims to support the conceptual modeling of metadata or information about resources in the form of a directed graph composed of triples of knowledge (facts). RDF also provides mechanisms to encode meta-information (such as source, trust, and certainty) about facts already existing in a knowledge base through a process called reification. In this thesis, an extension to the current RDF specification is proposed in order to enhance RDF triples with an application specific weight (cost). Unlike reification, this extension treats these additional weights as first class knowledge attributes in the RDF …

ABSTRACT Forgiveness is a response to moral wrongdoing motivated by moral reasons. Long thought to be the overcoming of resentment, I will present T.M. Scanlon's view that it is best understood as the decision to blame no longer, i.e. to give up the judgment that one's relationship with another is impaired. Forgiveness has been traditionally thought of as having its locus in the forgiver. However, this has led to a number of accounts in which forgiveness has been presented as a one-sided undertaking, compromising the interpersonal character of the act. I propose a different way of viewing forgiveness, namely as …

The impact of urbanization on wildlife is becoming an important topic in conservation. However little is known concerning the proximate mechanisms involved which enable some species to persist in cities, while others perish. Adapting to novel city environments requires individuals to maintain a functional physiological response to stressful stimuli, while concurrently using the necessary resources (food) needed to persist. A primary function of the stress response is the mobilization of intrinsic energy resources, and thus both requirements (energy and stress) are explicably linked.

Receiver Operating Characteristic (ROC) analyses were computed to determine the utility of GAI-CPI difference scores to identify children with ADHD. …

Thermal modeling and investigation into heat extraction methods for building-applied photovoltaic (BAPV) systems have become important for the industry in order to predict energy production and lower the cost per kilowatt-hour (kWh) of generating electricity from these types of systems. High operating temperatures have a direct impact on the performance of BAPV systems and can reduce power output by as much as 10 to 20%. The traditional method of minimizing the operating temperature of BAPV modules has been to include a suitable air gap for ventilation between the rooftop and the modules. There has been research done at Arizona State …
