Perturbation Formulas For Gross-Pitaevskii Equation With Periodic Potential, Seonguk Kim Jan 2016

Perturbation Formulas For Gross-Pitaevskii Equation With Periodic Potential, Seonguk Kim

All ETDs from UAB

Gross-Pitaevskii equation (GPE), which was introduced in early 1960s, is widely used in several areas, such as condensed matter physics, and nonlinear optics. The purpose of this thesis is to carry out mathematical studies for GPE. We concentrate on extended solutions of GPE. This thesis mainly contains three parts. The first part is to investigate explicit perturbation formulas for stationary solutions close to a plane wave and their corresponding energies for the nonlinear polyharmonic equation when 2l > n, where n is dimension and l is a power of the Laplacian. The main idea is to consider a non-linear term as …

Detection And Str Profiling Of Saliva Remaining In Water Bottles, Brittany Kriz Jan 2016

Detection And Str Profiling Of Saliva Remaining In Water Bottles, Brittany Kriz

All ETDs from UAB

As instruments for detecting DNA have become more sensitive and reagents for amplifying DNA become more effective, forensic DNA analysts have obtained short tandem repeat (STR) profiles from evidence containing a small amount of DNA. Sources, such as dandruff, sweat, and saliva, which were once thought to be inadequate for STR profiling, can now be analyzed to effectively establish a profile. These low quantities of DNA can be recovered from liquid samples, such as saliva, or extracted and concentrated from large volumes of buffer, then amplified to give a DNA profile. This study focused on recovering saliva from drinking containers. …

Non-Violent Resistance Vs. Passivity: A Look Into Percy Shelley's Politics In Prometheus Unbound, The Mask, And The Cenci, Kayla Lashae Light Jan 2016

Non-Violent Resistance Vs. Passivity: A Look Into Percy Shelley's Politics In Prometheus Unbound, The Mask, And The Cenci, Kayla Lashae Light

All ETDs from UAB

This thesis explores the differences between passiveness in Percy Shelley and Martin Luther King Jr.’s works by sectioning it off into types of passiveness: positive and negative passivity. Positive passivity is equated with a non-violent resistance, and negative passivity is the refusal or fear of acknowledging evil. Shelley and King agree that this type of evil is the most prominent among common people. In Shelley’s, Cenci, Mask of Anarchy, and Prometheus Unbound, readers can see how he is using minor characters and some major characters to illustrate oppression. King’s works, however, use personal examples and a more direct narrative. Even …

Understanding Protein-Protein Interactions In Plantae In Network Biology Utilizing A Novel Y2h Liquid Assay Approach, Jessica Lopez Lopez Jan 2016

Understanding Protein-Protein Interactions In Plantae In Network Biology Utilizing A Novel Y2h Liquid Assay Approach, Jessica Lopez Lopez

All ETDs from UAB

The Yeast-2-Hybrid (Y2H) assay is a heterologous system that is expanding network biology knowledge via in vivo investigations of binary protein-protein interactions. Traditionally, the Y2H protocol entails the mating or co-transformation of yeast in solid agar media followed by visual analysis for diploid selection. Having played a key role in identifying protein-protein interactions for nearly three decades, the Y2H system includes the interaction between two proteins of interest which result in a reconstituted transcription factor allowing a reporter gene to be transcribed. In this thesis, two primary objectives were pursued to expand the knowledge of protein-protein interactions. The primary objective …

Hard/Soft Metal Binding To Phosphorus-Donor Functionalized Transition Metal Complexes, Justin R. Martin Jan 2016

Hard/Soft Metal Binding To Phosphorus-Donor Functionalized Transition Metal Complexes, Justin R. Martin

All ETDs from UAB

The synthesis, characterization, and hard/soft metal binding abilities of a series of novel phosphite- and phosphinite-functionalized transition metal complexes are reported. Many of these compounds have applications as molecular sensors or as alkene hydro-formylation catalysts. The first chapter investigates a series of cis-tetracarbonylmolybdenum(0) com-plexes prepared from α,ω-bis(phosphite)-polythioether ligands. Their syntheses have been optimized, and solid-state structures of the complexes, as well as one of the synthet-ic by-products, are reported. The abilities of the metallathiacrown ethers to bind MCl2 (M = Hg, Pt, Pd) have been assessed using 31P{1H} NMR spectroscopy and X-ray crystallog-raphy. These studies show that the compounds do …

Changes In Intrinsic Local Functional Connectivity In Children With Autism Followed By A Visualizing/Verbalizing Reading Intervention, Jose Omar Maximo Jan 2016

Changes In Intrinsic Local Functional Connectivity In Children With Autism Followed By A Visualizing/Verbalizing Reading Intervention, Jose Omar Maximo

All ETDs from UAB

Deficits in language are a major clinical feature of autism spectrum disorders (ASD). Previous studies suggest that individuals with ASD may rely on visuospatial skills to compensate for these deficits. Existing intervention programs in autism have not been tested at the neural level, thus falling short of quantifiable neurobiological changes underlying behavioral improvement. The current study takes a translational neuroimaging approach to test the impact of a structured visual imagery-based reading intervention on improving reading comprehension and its underlying neural circuitry. Changes in connectivity of a set of brain regions commonly known as the “reading network” were examined in children …

Improving The Scalability Of Directed Model Checking Of Concurrent Java Code Through Hybrid And Distributed Analysis, Reed Morgan Milewicz Jan 2016

Improving The Scalability Of Directed Model Checking Of Concurrent Java Code Through Hybrid And Distributed Analysis, Reed Morgan Milewicz

All ETDs from UAB

Since the widespread adoption of multi-core architectures at the turn of the millennium, parallel and concurrent programming paradigms, such as multi-threaded programming, have been advanced to enable programmers to take advantage of this abundance of computational resources. However, the need for speed has also given new life to ancient evils, namely concurrency bugs. The term concurrency bug, broadly speaking, refers to any bug that arises due to improper or inadequate synchronization of threads in their use of shared resources. These include deadlocks, race conditions, and atomicity violations. Model checking has proven to be a powerful and versatile approach to the …

A Comprehensive Investigation Of Hp1b, A Chromatin Protein, And Its Role In Aging, Benjamin Mills Mills Jan 2016

A Comprehensive Investigation Of Hp1b, A Chromatin Protein, And Its Role In Aging, Benjamin Mills Mills

All ETDs from UAB

Genetic regulation determines which genes are expressed, in which tissues, at which time, and to which level. This regulation is necessary for proper organismal development, and loss of gene regulation can result in phenotypic consequences. As organisms grow older, gene regulation often begins to fail, resulting in negative phenotypic outcomes associated with aging. The exact reason for this failure of gene regulation remains unknown, but current models suggest that chromatin, and its associated proteins, plays a large role. The structure of chromatin impacts gene expression, directly affecting several phenotypes including aging. In this study, we investigate HP1B, a chromatin protein, …

Machine Learning Of Composite Concepts And The Alleviation Of The Content Completeness Problem In Text Mention Normalization, John David Osborne Jan 2016

Machine Learning Of Composite Concepts And The Alleviation Of The Content Completeness Problem In Text Mention Normalization, John David Osborne

All ETDs from UAB

A critical area in the field of information extraction is the assignment of ontological categories (meaning) to fragments of natural language. These fragments are termed ``utterances'' when referring to a continuous fragment or ``mentions'' when the fragment may be discontinuous. In text, most approaches to ontological assignment use named entity recognition (NER) to first discover mention boundaries. This can then be followed by a concept recognition or normalization process to assign a more precise conceptual category to the NER discovered mention. Typically this semantic assignment is represented by only a single identifier from an ontology. If the provided semantic categories …

Joint Intervention In Opposing Pathways, Pi3k/Akt And Tgf-Beta, With Px-866 And Raloxifene, To Alter Gene Expression And Suppress Estrogen Receptor-Positive Breast Cancer Cell Proliferation, Gregory William Peek Jan 2016

Joint Intervention In Opposing Pathways, Pi3k/Akt And Tgf-Beta, With Px-866 And Raloxifene, To Alter Gene Expression And Suppress Estrogen Receptor-Positive Breast Cancer Cell Proliferation, Gregory William Peek

All ETDs from UAB

For each regulatory pathway implementing environmental or internal messages, there is at least one additional pathway to relay a message to override or modify the original message, in the event of new or conflicting input. The opposing pathway may also be an instrument for negative feedback or redundancy as well as for transmission of additional encountered conditions or considerations. Because the multiple disease conditions based on aberrant cell cycle proliferation often require a level of correction independent of opposing feedback, selection of opposing pathways for complementary joint input is a practical approach to cancer and related proliferation-associated diseases. Accordingly, I …

Study Of Cobalt, Cobalt-Iron, And Chromium Doped Ii-Vi Media For Laser Applications, Jeremy M. Peppers

All ETDs from UAB

The middle infrared (mid-IR) spectral range of 2-15 μm possesses characteristics that make it interesting for a number of applications such as spectroscopy, free-space communication, remote detection of organic compounds, materials processing and medical diagnosis. Many organic molecules exhibit strong absorption in this spectral range, rendering their detection and identification possible. There also exist bands of atmospheric transmission which can allow free-space propagation of mid-IR light over considerable distances within the atmosphere. Because of these, there is an increasing demand for broadly tunable laser sources operating in this spectral range. II-VI wide bandgap semiconductor hosts doped with transition metal (TM) …

Neural Network Associated With The Psychobiological Response To Stress, Muriah Wheelock Jan 2016

Neural Network Associated With The Psychobiological Response To Stress, Muriah Wheelock

All ETDs from UAB

The biobehavioral response to acute stress is an allostatic process. Dysregulation of the stress response has been implicated in allostatic load and the pathophysiology of a wide range of physical and psychological disorders. There have been considerable advances within the last two decades in the field’s understanding of allostatic load and a consistent finding across studies has been that individual differences are the norm rather than the exception. That is, exposure to stress seems to have minimal negative consequences for some, but substantial negative consequences for others. Determining the neural processes associated with individual differences in stress reactivity may advance …

Temporal Co-Expression Network Construction, Leading Sub-Network Identification, And Time Point Alignment In The Integration Of Phase Transition Theory And Systems Biology And The Application To Human Type 1 Diabetes, Nathaniel Wolanyk

All ETDs from UAB

Systems biology is a rapidly expanding field used to tackle a wide range of biological problems. Systems biology arose to explain areas that detailed biological analysis, such as genetics and biopsies, struggled with. Systems biology is the study of the complexity within a biological system of multiple units that is due to the interaction among the units. In this dissertation systems biology will be combined with phase transition theory from physics to create a new analysis method for complex diseases and apply this new method to a longitudinal dataset on Type 1 Diabetes (T1D) to identify the key contributing molecules …

All ETDs from UAB

Treatment in this case of motor complete high tetraplegia began 22 months after injury. Electromyographic biofeedback was used to strengthen weak muscle contractions in the right upper arm to obtain limb movement. The newly emerging movement was trained by shaping to enable functional movements: controlling a wheelchair with a joystick, using a computer mouse for typing, and bringing the hand to mouth for self-feeding and facial hygiene with the aid of a Swedish Help Arm counterweight system. Some individuals with high tetraplegia may have heretofore unexplored capacity for late motor recovery with appropriate noninvasive training.

Trustworthy And Efficient Digital Forensics In The Cloud, D M Shams Zawoad Jan 2016

Trustworthy And Efficient Digital Forensics In The Cloud, D M Shams Zawoad

All ETDs from UAB

The rise of cloud computing has changed the way of using computing services and resources. However, the black-box nature of clouds and the multi-tenant cloud models have brought new security risks, especially in terms of digital forensics. Current cloud computing architectures often lack support for digital forensic investigations since many of the assumptions that are valid for traditional computing environment are invalid in clouds. Current digital forensics tools and procedures rely on the physical access to the evidence. In clouds, computing and storage resources are no longer local and these resources are also shared between multiple cloud users. Hence, even …

Writing Centers Across The Curriculum: Reimagining Writing Centers Through Writing Across The Curriculum And Human Resource Management, Adele Leon

All ETDs from UAB

Current research in Writing across the Curriculum theory and writing center assessment shows concerns for students being able to connect their writing to their disciplines. However, little is being said about connecting writing centers to WAC programs, and less is being said about having writing centers take on the role of a WAC program. This thesis addresses the possibility of the latter, and creating a Writing Centers Across the Curriculum program to better help students across the disciplines connect their writing to their majors. In the creation of a WCAC program, a strong focus on training writing center tutors through …

Changes In Quality Of Life Following Substance Use Disorder Treatment For Mentally Ill Homeless Individuals, Lauren Hayes Jan 2016

Changes In Quality Of Life Following Substance Use Disorder Treatment For Mentally Ill Homeless Individuals, Lauren Hayes

All ETDs from UAB

Quality of life (QOL) is a treatment outcome for substance use disorders that has largely been overlooked. Research suggests QOL is poor among persons with substance use disorders, even following treatment, but is unclear if this is primarily attributable to substance abuse itself or other life areas. Some evidence suggests other factors are responsible for low QOL, such as psychiatric distress. This paper examined QOL, its changes following treatment, and its contributors in two substance use disorder treatment studies (Homeless IV and EARTH) among persons who are homeless with co-occurring disorders. The purpose was to evaluate whether psychiatric distress should …

Racial Disparities In Cognitive Performance In Older Adults With Diabetes, Samantha Kaytana Henry Jan 2016

Racial Disparities In Cognitive Performance In Older Adults With Diabetes, Samantha Kaytana Henry

All ETDs from UAB

ABSTRACT Racial disparities on measures of cognitive performance are well-documented. The purpose of the current study was to examine education quality and health factors in explaining racial differences in cognitive performance. It was hypothesized that significant differences in test performance between African Americans and Caucasians would remain robust despite controlling for demographics. However, accounting for education quality and diabetes-related factors was expected to reduce racial differences to nonsignificance. Additionally, racial differences between objective test performance and subjective memory ratings were anticipated. The sample consisted of 247 older African American and Caucasian adults with diabetes in the Birmingham area. Participants completed …

"Sleep Tight, Don't Let The Dysfunction Bite!" The Relationship Between Sleep Problems And Behavioral And Emotional Problems In Adolescence, Meredith Ashley Henry Jan 2016

"Sleep Tight, Don't Let The Dysfunction Bite!" The Relationship Between Sleep Problems And Behavioral And Emotional Problems In Adolescence, Meredith Ashley Henry

All ETDs from UAB

The effects of sleep on behavioral and emotional functioning in a low income, urban sample of 84 African American adolescents was investigated over 3 years (mean ages: 13.36, 14.76, and 16.14 years) of parent and child interviews. Results suggest child-reported sleep duration decreased while all other sleep variables remained stable. Substance use increased over time. Physical aggression and conduct problems decreased; depression, emotional problems, and hyperactivity/inattention remained stable until late adolescence and then decreased. Lower duration of sleep and more sleep problems at age 13 predicted more conduct problems at age 15 which, in turn, predicted less sleep duration and …

Andy Loves Richard: The Revelations Of Vote Mcgovern (1972), Amelia Hobson

All ETDs from UAB

In 1972, Pop artist Andy Warhol was asked by the Democratic National Convention to design a poster for the campaign of George McGovern in his race against presidential incumbent Richard Nixon. The final print was produced in an edition of 250 prints and sold at auction with the proceeds donated to McGovern’s campaign. The work commands almost immediate attention as it depicts not George McGovern, as might be expected, but his opponent President Richard Nixon. Nixon’s head consumes the greater portion of the print and looms over the scrawled text, “VOTE MCGOVERN.” Nixon’s eyes are yellow and his face green …

Race Effects Of Perceived Weight Status And Its Relationship With Unmet Health Care Need, Sarah B. Rutland Jan 2016

Race Effects Of Perceived Weight Status And Its Relationship With Unmet Health Care Need, Sarah B. Rutland

All ETDs from UAB

This study (n=9,630) evaluates the influence of race on the relationship between perceived weight status (PWS) and obtaining health care when a respondent thought care was needed (unmet need) among young adults (age 24-34) using Wave IV of the National Longitudinal Study of Adolescent to Adult Health. Using the framework of fundamental cause, I assume that health disparities between groups is due to unequal distribution of resources between those groups that enables a group with more resources, such as wealth or race privilege, to access and support better health outcomes. I focus on race, and specifically racism, as a resource …
