Keller-Segel Type Chemotaxis Model: Asymptotic Behavior Of The Small Data Solution, Jean D. Rugamba Jan 2021

Keller-Segel Type Chemotaxis Model: Asymptotic Behavior Of The Small Data Solution, Jean D. Rugamba

All ETDs from UAB

This dissertation’s work is on asymptotic behavior of a Keller- Segel type chemotaxismodel with logarithmic sensitivity and logistic growth. The logarithmic singularity in the system is removed via the inverse Hopf-Cole transformation. Then, for the transformed system, we study the Green’s function of the corresponding linear system, linearized around a constant equilibrium solution, and the results give us a detailed point-wise description of the Greens function, which, itself, is significant in linear theory. Next, with the results on the Green’s function, we study small data solution to the nonlinear system by making use of Duhamel’s principle. This provides a descriptive …

Tensor Completion And Total Variation Denoising And Deblurring In Tensor Spaces, Fatoumata Sanogo

All ETDs from UAB

Tensor completion is a higher-order generalization of matrix completion where the goal is to recover a low-rank tensor from a partially observed tensor. Here we work on a numerical method to reconstructs a tensor (matrix) with missing entries by finding the optimal factors through linear least squares and the singular vector through a proximal algorithm of soft thresholding. The performance of our algorithm is tested on color images and surveillance videos.In addition, we continued working on those algorithm to get an optimal way of finding the regularization parameter to improve the quality of our output. For this purpose we used …

Applications Of Longitudinal Machine Learning Methods In Multi-Study Alzheimer's Disease Datasets, Charles F. Murchison

All ETDs from UAB

Advances in statistical learning models for prediction have led to broader application across a variety of disciplines, granting generalizations and adaptations that were previ-ously intractable even with advanced computational techniques. Among these is the al-lowance of correlated data with inherent paneled structure such as longitudinal or clus-tered data; adjustments which have already begun to be applied to a variety of supervised and unsupervised machine learning methods which had previously focused on cross-sec-tional data. These modifications have seen rudimentary testing in a number of applied disciplines where correlated data is commonly observed, including medical and clinical research. One field in particular …

Studies On Nontypeable Haemophilus Influenzae Biofilm Persistence & Redox Homeostasis In Chronic Bacterial Diseases, Benjamin C. Hunt Jan 2021

Studies On Nontypeable Haemophilus Influenzae Biofilm Persistence & Redox Homeostasis In Chronic Bacterial Diseases, Benjamin C. Hunt

All ETDs from UAB

Bacterial biofilms, or surface-adherent bacterial communities surrounded by a self-produced extracellular polymeric matrix, are ubiquitous. They are found throughout Earth’s ecosystems, in the soil and waterways, and more pressingly for the medical community, they are found within humans. Bacterial biofilms are associated with a multitude of diseases and their involvement significantly complicates treatment given that bacteria growing within a biofilm are extremely more resistant to antibiotics and immune effectors. Thus, the need to better understand biofilm biology and find ways to disrupt and/or sensitize biofilms to medical treatment is significant. The goal of the research presented herein was to investigate …

Tau-Sh3 Interactions And Alzheimer's Disease, Jonathan Roth Jan 2021

Tau-Sh3 Interactions And Alzheimer's Disease, Jonathan Roth

All ETDs from UAB

Alzheimer’s disease (AD) is the most common neurodegenerative disorder worldwide, and its impact will increase with an aging population. It is characterized by dementia associated with accumulation of extracellular amyloid-β (Aβ) plaques, intracellular hyperphosphorylated Tau tangles, and neurodegeneration. Additionally, network hyperexcitability occurs early in AD and likely contributes to disease pathogenesis. Current therapies provide minor delay of disease progression at best, so it is imperative to develop novel therapeutic approaches to prevent and treat AD. As Tau pathology correlates better with cognitive function than Aβ pathology and Tau reduction prevents Aβ-induced dysfunction in preclinical models, targeting Tau is a growing …

Low Illumination Video Enhancement Based On Machine Learning, Mohsine Taarji Jan 2021

Low Illumination Video Enhancement Based On Machine Learning, Mohsine Taarji

All ETDs from UAB

ow-brightness and image noise are common problems in computer vision that prohibit useful information extraction from video sequences. This problem is caused by insufficient illumination, low-quality cameras, external disturbances, and other factors. Dark image enhancement requires improvement of intensity and saturation; the missing data could be replaced by matching image regions using image feature detector-descriptor pairs. We proposed new metrics for evaluating image descriptors with regard to their uniqueness. Also, we developed new image enhancement techniques based on HSV color space. The idea behind the first contribution of our dissertation is to find the best descriptor that match pixels from …

Functions Of Drosophila Hp1 Proteins In Transcriptional Regulation, John Schoelz Jan 2021

Functions Of Drosophila Hp1 Proteins In Transcriptional Regulation, John Schoelz

All ETDs from UAB

The Heterochromatin Protein 1 (HP1) family are a group of non-histone chromosomal proteins with functions in many essential DNA processes. The HP1 family is highly conserved, and many eukaryotic genomes contain multiple HP1 genes. Individual paralogs specialize in specific functions, although they do have overlapping roles in some processes. In Drosophila, there are three HP1 paralogs expressed in somatic cells: HP1a, HP1B and HP1C. All three of these proteins have previously been implicated in both the positive and negative regulation of transcription. Furthermore, the three proteins share binding sites and colocalize broadly throughout the Drosophila genome. Here, we investigate individual …

Effeccts Of Hiv-1 Tat On Tspo, A Biomarker Of Neuroinflammation, Nguyen Thuy Nhu Nguyen

All ETDs from UAB

HIV-associated neurocognitive disorders (HAND) produces serious neurological dysfunction for > 50% of people living with HIV (PLWH). As antiretroviral therapy (ART) has transformed HIV into a chronic disease, and since most ART does not effectively cross the blood brain barrier, HAND is predicted to further increase in prevalence in PLWH. The HIV-Trans-Activator of Transcription (Tat) is known to persist in the central nervous system (CNS) of chronically infected HIV+ individuals. In several preclinical studies, HIV-Tat has been shown to be neurotoxic and important for HIV pathogenesis. Translocator protein (TSPO), an 18 kDa mitochondrial protein, has been shown to be increased via …

Characterization Of Rna Polymerase I Trigger Loop Mutations, Collin Ainslie

All ETDs from UAB

RNA polymerases are primarily multi-subunit enzymes that synthesize RNAs from template DNA strands. RNA polymerase I (Pol I) is the eukaryotic RNA polymerase that synthesizes the majority of ribosomal RNA (rRNA) for ribosome production. These include the 5.8S, 28S, and 18S rRNAs which are synthesized from a polycistronic gene in the nucleolus. The rRNAs synthesized by Pol I, the 5S rRNA, & ribosomal proteins come together to synthesize ribosomes through ribosome biogenesis. Dysregulation of Pol I activity has been established to contribute to dysregulation of ribosome biogenesis and disease state development. These conditions include but are not limited to Cincinnati …

A Stress Process Approach To Assessing Caregiver Burden, Depressive Symptoms, And Quality Of Life: The Role Of Attachment In Adult Relationships, Ghislaine Celine Atkins

All ETDs from UAB

Aging adults (65 years and older) are projected to be the largest age group in the United States by around the year 2030. Importantly, the population of aging adults is expected to outnumber their adult children for the first time by the year 2033. The extant literature posits that the majority of carer-care-recipient relationships are between adult children/in law and their aging parent or a spouse/partner. Familial carers dealing with these multiple stressors are more likely to exhibit depressive symptoms, have higher appraisals of stress and have worse quality of life. This dissertation project utilized sociologist Pearlin’s Stress Process Model …

Characterization Of Cellular And Viral Factors That Define The Stability Of The Latent Hiv-1 Reservoir, Eric Carlin Jan 2021

Characterization Of Cellular And Viral Factors That Define The Stability Of The Latent Hiv-1 Reservoir, Eric Carlin

All ETDs from UAB

Human immunodeficiency virus (HIV) infection is a chronic viral illness that requires lifelong management due to the early formation of a latent viral reservoir within the patient’s CD4+ T cells. These latent infection events lay dormant within infected cells and reactivate stochastically or during periods of T cell activation presenting a major hurdle to the development of an HIV cure. As our understanding of the factors that contribute to HIV latency has evolved, we have started to appreciate latency as more than a chromatin regulation phenotype, due to the vast number of cellular factors that have been described to impact …

Tgfβ Provides The Backbone Of Embryogenesis: Elucidating The Role Of Tgfβ Signaling And Its Downstream Effectors On Spinal Column Development, Sade Williams Clayton Jan 2021

Tgfβ Provides The Backbone Of Embryogenesis: Elucidating The Role Of Tgfβ Signaling And Its Downstream Effectors On Spinal Column Development, Sade Williams Clayton

All ETDs from UAB

The spinal column is composed of two components, the vertebra (VB) that provide support and the intervertebral disc (IVD) that provide weight distribution. The structural integrity of IVDs is maintained by a fibrocartilaginous tissue called the annulus fibrosus (AF) which can degenerate with age or trauma and contribute to chronic back pain. There are currently no diseases modifying treatments that curb IVD degeneration. Regenerative therapies to treat IVD degeneration can be developed from identifying the signaling factors required for AF differentiation, but these factors are unknown. Previously, we showed that TGFβ signaling is required for AF formation in mice and …

Hurricanes And Heart Problems: Natural Disaster, Social Capital, And Cardiovascular Mortality, Zachary H. Mccann Jan 2021

Hurricanes And Heart Problems: Natural Disaster, Social Capital, And Cardiovascular Mortality, Zachary H. Mccann

All ETDs from UAB

Social capital refers to the social relationships and structures that provide individuals with material, financial, and emotional resources throughout their lives. Previous research has found an association between high levels of social capital and lower rates of all-cause and cardiovascular disease (CVD) mortality. Severe disasters have been linked to higher rates of all-cause and CVD mortality. In post-disaster settings social capital may be a valuable resource for protecting against both forms of mortality. Past research shows that social capital can improve access to resources, such as food, water, and medical supplies, that reduce all-cause and CVD mortality. Using previous research …

A Role For Inf-Ɣ-Inducble Transcription Factors In Antibody Secreting Cell Differentiation, Jessica N. Peel Jan 2021

A Role For Inf-Ɣ-Inducble Transcription Factors In Antibody Secreting Cell Differentiation, Jessica N. Peel

All ETDs from UAB

Viral infections remain a major cause of morbidity and mortality. Within a viral, interferon (IFN)-ɣ-driven inflammatory microenvironment, B cells may produce antibody which is critical for rapid viral clearance and continued protection from reinfection. However, the roles of IFN-ɣ and IFN-ɣ-induced transcription factors (TFs) in driving antibody secreting cell (ASC) development from their B cell precursors are poorly understood. Herein, we identify two IFN-ɣ-inducible transcription factors (TFs), T-bet and interferon regulatory factor 1 (IRF1), that are essential for the differentiation of ASCs from IFN-g-activated B cell precursors. T-bet repressed an IFN-ɣ-inducible inflammatory gene program that was incompatible with ASC formation …

Balanced Placebo Design With Varenicline: Pharmacological And Expectancy Effects On Medication Adherence, Samantha Schiavon Jan 2021

Balanced Placebo Design With Varenicline: Pharmacological And Expectancy Effects On Medication Adherence, Samantha Schiavon

All ETDs from UAB

Varenicline is one of the most efficacious smoking cessation medications. However, some individuals are unable to adhere to the 12-week medication regimen, primarily due to side effects. Although these side effect may be due to the pharmacological effects of varenicline, there may also be a psychologically rooted explanation (i.e., nocebo effects). Varenicline was once believed to cause serious adverse events and although this has been refuted, concerns regarding its use continue within the general population. This is the first study to differentiate psychological expectancies from pharmacological barriers as it relates to varenicline adherence. Varenicline naïve smokers (N=80) were randomized into …

Understanding The Role Of Biomechanics In Ovarian Cancer Biology, Alba Martinez Diaz Jan 2021

Understanding The Role Of Biomechanics In Ovarian Cancer Biology, Alba Martinez Diaz

All ETDs from UAB

Mechanical forces including compression, tension, and shear stress are increasingly implicated as instigators of tumor progression. Understanding how mechanobiology drives ovarian cancer is critical to identifying potential therapies. The effect of shear stress is beginning to be studied in ovarian cancer due to the presence of ascites in the peritoneal cavity that prompts tumor cells detachment and implantation in secondary sites. Therefore, mechanical cues are present within the peritoneal cavity. A growing ovarian tumor mass also experiences compressive and tensile forces, although their participation in tumor progression still remains unclear. Additionally, there is a specific lack of incorporation of mechanobiology …

Dynamic Biomechanical Characteristics Of The Optic Nerve Head By Oct Imaging, Jihee Kim Jan 2021

Dynamic Biomechanical Characteristics Of The Optic Nerve Head By Oct Imaging, Jihee Kim

All ETDs from UAB

Approximately 80 million people in the world were estimated to suffer from glaucoma in 2020. To date, lowering intraocular pressure (IOP) is the only clinical treatment to delay or prevent the development and progression of glaucomatous vision loss. However, many glaucoma patients have IOP in the normal range, while some people with abnormally high pressure do not develop neuropathy. This indicates that biomechanical responses of the optic nerve head (ONH) to changes in IOP can vary significantly among individuals. This study investigated acute IOP-induced compliance in the ONH via SDOCT imaging, using computer vision, and deep learning networks to improve …

Kink-Resistant Vascular Grafts With Integrated Capacitance-Based Hemodynamic Monitoring System, Kiran Raj Adhikari

All ETDs from UAB

Cardiovascular diseases (CVDs) are one of the leading causes of death in the United State and the number of cases is ever so increasing. The rises in the number of CVD patients are due to the increasingly hostile cardiovascular environments, indicated by poor diet, lack of exercise, socioeconomic and other stresses. The treatment often requires the replacement of blood vessels in the patients. For smaller diameter vascular grafts, the failure rate is high and the patency of these replaced grafts decreases significantly over the years. This failure is mostly due to a mismatch of the various properties between the native …
