Aether Unleashed, Christian Armendariz-Picon, Alberto Diez-Tejedor Nov 2009

Aether Unleashed, Christian Armendariz-Picon, Alberto Diez-Tejedor

Physics - All Scholarship

We follow a low-energy effective theory approach to identify the general class of theories that describes a vector field (of unconstrained norm) coupled to gravity. The resulting set may be regarded as a generalization of the conventional vector-tensor theories, and as a high-momentum completion of aether models. We study the conditions that a viable cosmology, Newtonian limit and absence of classical and quantum instabilities impose on the parameters of our class of models, and compare these constraints with those derived in previously studied and related cases. The most stringent conditions arise from the quantum stability of the theory, which allows …


Strangers And Intimates: A Collection Of Short Stories, Kathy Marie West Nov 2009

Strangers And Intimates: A Collection Of Short Stories, Kathy Marie West

Theses and Dissertations

This creative thesis includes five short stories that explore paradoxical ways in which people can feel alone, even if they are together. Although a combination of isolation and intimacy can occur in any human relationship, the stories in this collection spend much of their time with family circles in particular, considering the way that our closest, most permanent relationships can simultaneously prove the most intimate and the most isolating. The critical introduction that precedes the collection examines each story individually, discussing strategies and subject matter in terms of the collection's guiding concept. The introduction discusses the binary of intimacy and …


Hokua – A Wavelet Method For Audio Fingerprinting, Steven S. Lutz Nov 2009

Hokua – A Wavelet Method For Audio Fingerprinting, Steven S. Lutz

Theses and Dissertations

In recent years, multimedia identification has become important as the volume of digital media has dramatically increased. With music files, one method of identification is audio fingerprinting. The underlying method for most algorithms is the Fourier transform. However, due to a lack of temporal resolution, these algorithms rely on the short-time Fourier transform. We propose an audio fingerprinting algorithm that uses a wavelet transform, which has good temporal resolution. In this thesis, we examine the basics of certain topics that are needed in understanding audio fingerprinting techniques. We also look at a brief history of work done in this field. …


An Empirical Study Of Instance Hardness, Michael Reed Smith Nov 2009

An Empirical Study Of Instance Hardness, Michael Reed Smith

Theses and Dissertations

Most widely accepted measures of performance for learning algorithms, such as accuracy and area under the ROC curve, provide information about behavior at the data set level. They say nothing about which instances are misclassified, whether two learning algorithms with the same classification accuracy on a data set misclassify the same instances, or whether there are instances misclassified by all learning algorithms. These questions about behavior at the instance level motivate our empirical analysis of instance hardness, a measure of expected classification accuracy for an instance. We analyze the classification of 57 data sets using 9 learning algorithms. Of …

The Effect Of Stress On Hedonic Capacity In Generalized Anxiety Disorder: A Prospective Experimental Study Of One Potential Pathway To Depression, Bethany H. Morris Nov 2009

The Effect Of Stress On Hedonic Capacity In Generalized Anxiety Disorder: A Prospective Experimental Study Of One Potential Pathway To Depression, Bethany H. Morris

USF Tampa Graduate Theses and Dissertations

A growing body of work links psychopathology to changes in hedonic capacity following stressors. This was the first experimental study of the effects of stress on hedonic capacity in an analog generalized anxiety disorder (GAD) sample (a high worry group). Specifically, we utilized an experimental manipulation of stress and a behavioral index of anhedonia to test the hypothesis that individuals with GAD, who are at higher risk for developing depression symptoms, exhibit greater stress-related deficits in hedonic capacity than do nonanxious controls. Further, this study assessed whether stress-induced hedonic deficits predicted future depression. Controls exhibited the expected reward learning pattern …


Dyna-Mod Constructing The Modern Adaptable Home, Sarah Deardorff Nov 2009

Dyna-Mod Constructing The Modern Adaptable Home, Sarah Deardorff

USF Tampa Graduate Theses and Dissertations

The modern home has become a static fixture in society that is not reflected in the growing populous that is becoming an ever increasing mobile society. Many are not able to stay to the same place that they call home for long periods of time. Changing jobs, markets and neighborhoods force those to continue their movement around leaving what it is that they call their home to try and reproduce it within another location. The home finds itself lost in this transition and must now function on a greater adaptability than ever before and reflect the growing demand placed upon …

Quantifying And Resolving Multiple Vector Transformants In S. Cerevisiae Plasmid Libraries, Thomas C. Scanlon, Elizabeth C. Gray, Karl E. Griswold Nov 2009

Quantifying And Resolving Multiple Vector Transformants In S. Cerevisiae Plasmid Libraries, Thomas C. Scanlon, Elizabeth C. Gray, Karl E. Griswold

Dartmouth Scholarship

In addition to providing the molecular machinery for transcription and translation, recombinant microbial expression hosts maintain the critical genotype-phenotype link that is essential for high throughput screening and recovery of proteins encoded by plasmid libraries. It is known that Escherichia coli cells can be simultaneously transformed with multiple unique plasmids and thusly complicate recombinant library screening experiments. As a result of their potential to yield misleading results, bacterial multiple vector transformants have been thoroughly characterized in previous model studies. In contrast to bacterial systems, there is little quantitative information available regarding multiple vector transformants in yeast. Saccharomyces cerevisiae is the …

Slab-Coupled Optical Fiber Sensors For Electric Field Sensing Applications, Richard S. Gibson Nov 2009

Slab-Coupled Optical Fiber Sensors For Electric Field Sensing Applications, Richard S. Gibson

Theses and Dissertations

This dissertation presents the creation of slab coupled optical sensors (SCOS) for electric field sensing applications. SCOS devices utilize the benefits of an optical fiber system for high bandwidth and low electromagnetic interference. These sensors are fabricated by means of mode coupling between a small section of D-shaped optical fiber (D-fiber) with a multi-mode electro-optic slab waveguide. Electric field detection is accomplished by monitoring the behavior of the resonances, seen as transmission dips in the D-fiber transmission, as they shift with electric fields. The novelties of SCOS devices include their small compact nature, potential for sensor multiplexing and a dielectric …

Recent comprehensive sequence analysis of the maize genome now permits detailed discovery and description of all transposable elements (TEs) in this complex nuclear environment. Reiteratively optimized structural and homology criteria were used in the computer-assisted search for retroelements, TEs that transpose by reverse transcription of an RNA intermediate, with the final results verified by manual inspection. Retroelements were found to occupy the majority (>75%) of the nuclear genome in maize inbred B73. Unprecedented genetic diversity was discovered in the long terminal repeat (LTR) retrotransposon class of retroelements, with >400 families (>350 newly discovered) contributing >31,000 intact elements. The …

Most of our understanding of plant genome structure and evolution has come from the careful annotation of small (e.g., 100 kb) sequenced genomic regions or from automated annotation of complete genome sequences. Here, we sequenced and carefully annotated a contiguous 22 Mb region of maize chromosome 4 using an improved pseudomolecule for annotation. The sequence segment was comprehensively ordered, oriented, and confirmed using the maize optical map. Nearly 84% of the sequence is composed of transposable elements (TEs) that are mostly nested within each other, of which most families are low-copy. We identified 544 gene models using multiple levels of …


Regulation Of The Alr1 Transporter By Mg Supply, Phaik Har Lim Nov 2009

Regulation Of The Alr1 Transporter By Mg Supply, Phaik Har Lim

Theses

Magnesium is required for many essential processes and pathways, including protein synthesis and energy metabolism. In the yeast Saccharomyces cerevisiae, Mg2+ uptake across the plasma membrane primarily occurs via the magnesium transporter Alr1. Preliminary data had shown that Alr1-HA accumulation was decreased by Mg. Here I show that the epitope tag was responsible for this differential accumulation of Alr1, as native or N-terminally tagged Alr1 displayed much less differential accumulation. Immunoblotting and Ni2+ uptake assays indicated that both Mg-deficiency and the mnr2 mutation increased Alr1 activity, but under conditions where native protein accumulation was little affected. Since Mg-dependent regulation of …


Modulation Of Outer Hair Cell Electromotility By Cochlear Supporting Cells And Gap Junctions, Ning Yu, Hong-Bo Zhao Nov 2009

Modulation Of Outer Hair Cell Electromotility By Cochlear Supporting Cells And Gap Junctions, Ning Yu, Hong-Bo Zhao

Surgery Faculty Publications

Outer hair cell (OHC) or prestin-based electromotility is an active cochlear amplifier in the mammalian inner ear that can increase hearing sensitivity and frequency selectivity. In situ, Deiters supporting cells are well-coupled by gap junctions and constrain OHCs standing on the basilar membrane. Here, we report that both electrical and mechanical stimulations in Deiters cells (DCs) can modulate OHC electromotility. There was no direct electrical conductance between the DCs and the OHCs. However, depolarization in DCs reduced OHC electromotility associated nonlinear capacitance (NLC) and distortion products. Increase in the turgor pressure of DCs also shifted OHC NLC to the negative …

Ethnic Effects On Biological, Psychosocial And Disease Care Factors In African-American Youth With Type 1 Diabetes, Priscilla Powell Nov 2009

Ethnic Effects On Biological, Psychosocial And Disease Care Factors In African-American Youth With Type 1 Diabetes, Priscilla Powell

Theses and Dissertations

Person-oriented and variable-oriented analyses were conducted to investigate sociodemographic differences in biological, psychosocial and disease care factors in youth with type 1 diabetes. Additionally, diabetes knowledge was evaluated as a potential mediator of SES effects on HbA1c and disease care. The sample included 349 youth, age 9-17 years (79.9% Caucasian, 71.3% lived with two biological parents, M SES = 46.24). Person-oriented t-tests confirmed commonly reported ethnic differences in HbA1c and disease care behaviors. However, variable-oriented analyses controlling for confounding sociodemographic influences showed most disease care effects attributed to ethnicity were better explained by SES. While diabetes knowledge was not a …

The Tragedy Of Nigel Rain, Jason W. Dockery Nov 2009

The Tragedy Of Nigel Rain, Jason W. Dockery

Theses

This work is a two-part collection of poems examining creative loss and gain and human dysfunction. The first part details the struggles of Nigel Rain, a persona born through an artist’s pen who finds himself abandoned by his creator. Nigel believes himself saved through the perpetuation of desire, and these poems show Nigel’s attempts at redefining his purpose in life by projecting his fortunes upon a woman he believes to be an embodiment of the Tarot card of helpful fortunes, the Star. Nigel’s tragedy is his failure to realize and ultimately survive the fragility of human connections. Language proves as …

Translated Opinions

Facts: The Knesset enacted the Prisons Ordinance Amendment Law (no. 28), 5764-2004 (‘amendment 28’), which provides that the State of Israel will establish, for the first time, a (single) prison that will be operated and managed by a private corporation rather than by the state. The constitutionality of this law was challenged by the petitioners, who argued that amendment 28 disproportionately violated the rights of prison inmates as a result of the actual transfer of imprisonment powers to a private enterprise, and as a result of the concern that human rights in a private prison would be violated to a …
