Counting Certain Quadratic Partitions Of Zero Modulo A Prime Number, Wang Xiao, Aihua Li Jan 2021

Counting Certain Quadratic Partitions Of Zero Modulo A Prime Number, Wang Xiao, Aihua Li

Department of Mathematics Faculty Scholarship and Creative Works

Consider an odd prime number p Ξ 2 (mod 3). In this paper, the number of certain type of partitions of zero in ℤ/pℤ is calculated using a combination of elementary combinatorics and number theory. The focus is on the three-part partitions of 0 in ℤ/pℤ with all three parts chosen from the set of non-zero quadratic residues mod p. Such partitions are divided into two types. Those with exactly two of the three parts identical are classified as type I. The type II partitions are those with all three parts being distinct. The number of partitions of each type …


Zero-Forcing In Random Regular Graphs, Deepak Bal, Patrick Bennett, Sean English, Calum Macrury, Pawe̷L Pra̷Lat Jan 2021

Zero-Forcing In Random Regular Graphs, Deepak Bal, Patrick Bennett, Sean English, Calum Macrury, Pawe̷L Pra̷Lat

Department of Mathematics Faculty Scholarship and Creative Works

The zero forcing process is an iterative graph colouring process in which at each time step a coloured vertex with a single uncoloured neighbour can force this neighbour to become coloured. A zero forcing set of a graph is an initial set of coloured vertices that can eventually force the entire graph to be coloured. The zero forcing number is the size of the smallest zero forcing set. We explore the zero forcing number for random regular graphs, improving on bounds given by Kalinowski, Kam˘cev and Sudakov [15]. We also propose and analyze a degree greedy algorithm for finding small …

Wellness and wellbeing have been a national priority in the United States of American for many years. Since 1961, wellbeing models have been created and reconstructed to define our understanding of what wellbeing is as well as what it should or could potentially be. These endeavors have contributed to a body of research that serve as a foundation for this study. The aim of this study was to review current theory and design a qualitative study to determine if current theory could be expanded upon utilizing religion, spirituality, faith and centeredness as central grounding principles for the model. This was …


Upregulation Of Somatostatin Receptor 2 In Neuroendocrine Tumors Using Histone Deacetylase Inhibitors, Rachael Elizabeth Guenter Jan 2021

Upregulation Of Somatostatin Receptor 2 In Neuroendocrine Tumors Using Histone Deacetylase Inhibitors, Rachael Elizabeth Guenter

All ETDs from UAB

Neuroendocrine cancer is complex disease of the diffuse neuroendocrine system. Neuroendocrine tumors (NETs) can arise throughout the body, including the lungs and pancreas. These tumors are phenotypically and genetically heterogeneous, making accurate diagnoses difficult with current imaging standards. New diagnostic options, coupled with a better understanding of neuroendocrine cancer etiology, is urgent and necessary to provide patients with better futures. Many NETs overexpress somatostatin receptor 2 (SSTR2) on their cellular surfaces, making patients eligible for [68Ga]-DOTATATE PET/CT imaging and SSTR2-based therapies. However, patients that lack sufficient SSTR2 overexpression cannot benefit from SSTR2-targeted imaging or therapeutic options. We found that histone …

Pulsed Laser Deposition Of Iron Selenide Heterostructures Guided By Laser-Plasma Simulations And Experiments, Sumner Bently Harris

All ETDs from UAB

This dissertation reports on advances in the areas of PLD synthesis of FeSe aswell as laser-plasma simulations. We demonstrate the epitaxial growth of novel FeSe-based materials and heterostructures which is heavily guided by laser plasma simulations and experiments. We show how in-situ plasma diagnostics can be used to measure and deliberately control the plasma properties in order to improve film quality and enable unique growth configurations. A model for laser ablation has also been developed and is directly compared to experiments. The combination of plasma diagnostics and simulations can make PLD a powerful, well-controlled platform for growth of new materials …


An Exploration Of The Manifestation Of Parentification Among Young Carers Of Persons With Huntington’S Disease, Bailey Hendricks Jan 2021

An Exploration Of The Manifestation Of Parentification Among Young Carers Of Persons With Huntington’S Disease, Bailey Hendricks

All ETDs from UAB

Due to the progressive deterioration of motor, cognitive, and psychological function experienced by individuals diagnosed with Huntington’s disease, there is the potential for children in the home to adopt a caregiving role. These young carers typically serve as informal, secondary caregivers, providing multifaceted, extended care without any lessening of typical family, home, or school/work-related responsibilities. In time, this role may result in parentification, a type of role reversal with both positive and negative outcomes for the child. A secondary analysis of qualitative data of the experiences of children who have a parent with Huntington’s disease was conducted. Transcripts of qualitative …


The Effects Of A Social Skills Intervention On Neural Processing In Autism Spectrum Disorder, Abbey Jane Herringshaw Jan 2021

The Effects Of A Social Skills Intervention On Neural Processing In Autism Spectrum Disorder, Abbey Jane Herringshaw

All ETDs from UAB

Difficulties in social interaction are considered a core characteristic of autism spectrum disorders (ASD) and have significant negative effects on quality of life in this population. Such deficits may reflect alterations in key areas of the “social brain” in ASD. Many clinical interventions for ASD seek to improve social interaction abilities, including the Program for Education and Enrichment of Relational Skills (PEERS®). PEERS® has demonstrated significant benefits for participants, but little is known about: 1) generalizability of the specific social knowledge gained to broader social cognitive processes, and 2) potential neuroplastic changes within the social brain in response to social …


Identifying Novel Therapeutics And Therapeutic Entry Points For The Treatment Of Duchenne Muscular Dystrophy Through Regulation Of Gene Expression, Rylie Maria Hightower Jan 2021

Identifying Novel Therapeutics And Therapeutic Entry Points For The Treatment Of Duchenne Muscular Dystrophy Through Regulation Of Gene Expression, Rylie Maria Hightower

All ETDs from UAB

My graduate research has primarily focused on genetic and epigenetic modifiers of Duchenne muscular dystrophy and understanding how those modifiers can be used as novel therapeutic entry points for treatment. A vast array of promising therapeutic strategies is being explored outside the realm of directly targeting dystrophin deficiency. This is primarily due to the lack of successful clinical trials that have demonstrated the ability to benefit a significant number of DMD patients. Here, I have expanded the field’s understanding of using the regulation of gene expression as a way to target dystrophin-deficiency associated pathology through, 1) therapeutic treatment of a …


Stress, Inflammation, And Mood: A Role For Leptin?, Kathleen Hodgin Jan 2021

Stress, Inflammation, And Mood: A Role For Leptin?, Kathleen Hodgin

All ETDs from UAB

Prior research has suggested a possible role for the proinflammatory adipokine leptin in depression. Leptin has also been associated with stress, a known predictor of depression. The purpose of this project was to investigate associations between stress, leptin, and depressed mood. We used data from a larger observational study that collected daily levels of plasma leptin and self-reported stress and depressed mood from 55 women over 25 days. Women with and without chronic fatigue syndrome (CFS) were included. We hypothesized the following: increased stress would be associated with both worsened mood and higher leptin, and that leptin would be positively …

Undergraduate Students’ Perspectives On Mental Health Services, Resources, And Supports During Covid-19: A Qualitative Dissertation, Amy Hutson Chatham

All ETDs from UAB

During the COVID-19 pandemic, increased isolation from supportive relationships, uncertainty about the future, fear of illness, and lack of traditional life-events took a toll on university student mental health. It is important to understand undergraduate students’ mental health needs during the COVID-19 pandemic and their desires for support from their institutions of higher education. Existing studies have documented increased rates of depression, stress, and anxiety among university undergraduates; however, these studies rarely illuminate students’ perspectives on mental health services, resources, and supports that they need during and because of the COVID-19 pandemic. This phenomenological study explored the perspectives of undergraduate …

Man Enough: Exploring The Gendered Experiences Of High-Achieving Black Men In Higher Education, Christopher E. Jones Jan 2021

Man Enough: Exploring The Gendered Experiences Of High-Achieving Black Men In Higher Education, Christopher E. Jones

All ETDs from UAB

Research regarding Black males in higher education has become an important endeavor for colleges and universities seeking to increase their graduation rates. Much of the previous research and practices have used a deficit-based approach explaining Black males’ low levels of academic achievement as primarily the result of them being underprepared. This ignores the contributions of Black males who do excel academically while minimizing the role their racialized gender plays in their outcomes. This dissertation focuses on an anti-deficit approach by exploring how high-achieving Black college males’ perceptions of manhood and masculinity have contributed to their overall academic success. Even though …


On The Security And Usability Of New Paradigms Of Web Authentication, Mohammed Jubur Jan 2021

On The Security And Usability Of New Paradigms Of Web Authentication, Mohammed Jubur

All ETDs from UAB

Passwords are widely used by web services to authenticate their users. Unfortunately, passwords suffer from several well-documented security and usability issues. The two of the main techniques to address password problems are password managers and two-factor authentication (2FA), which form the central focus of this dissertation work. In particular, we explore the security and usability of newly proposed and emerging forms of password managers and 2FA systems. We first investigate a “store-less” online password manager that can prevent the leakage of the passwords from the password manager service itself. We also design and evaluate a new 2FA scheme that offers …


Viral Load Is Not A Predictor For Hearing Loss In Children With Congenital Cytomegalovirus Infection, Nazia Kabani Jan 2021

Viral Load Is Not A Predictor For Hearing Loss In Children With Congenital Cytomegalovirus Infection, Nazia Kabani

All ETDs from UAB

Background: Congenital cytomegalovirus (cCMV) infection is a leading non-genetic cause of sensorineural hearing loss (SNHL) in children. Most infants (~90%) with cCMV have no clinical abnormalities at birth (asymptomatic cCMV), but 10-15% of these children develop SNHL. Due to lack of biomarkers, it is currently not possible to identify asymptomatic infants at-risk for hearing loss.Objective: To determine whether newborn viral load (VL) levels are predictive of hearing loss in children with asymptomatic cCMV. Methods: As part of the NIDCD CHIMES study, newborns at seven U.S. medical centers were screened for CMV by saliva PCR and enrolled in a follow-up study …

Laser Spectroscopy, Amplification, And Laser Properties Of Fe:Znse Mid-Ir Gain Media Under Er:Yag Laser Excitation, Krishna Karki

All ETDs from UAB

Many organic molecules exhibit strong and narrow absorption in the middle infrared (mid-IR) 2-8 μm and long-wavelength-infrared (LWIR) 8-20 μm spectral ranges. Hence, this infrared laser radiation is of interest for spectroscopy, remote sensing of atmospheric constituents, oil prospecting, as well as the number of applications such as free-space optical communication, laser surgical and dental treatment, and many defense-related applications. Transition metal (TM) doped II-VI semiconductors exhibit highly favorable spectroscopic properties for many mid-IR laser applications. Among these materials the most significant results have been obtained with the use of Fe:ZnSe crystals because of their unique properties such as broad …

Service Profiles In Substance Use Disorder Treatment: The Role Of Institutional And Organizational Factors, Reena Joseph Kelly

All ETDs from UAB

Substance use disorders (SUDs) are a growing crisis globally and in the US, and place an enormous health, social, and financial burden on the nation. To address the complex nature of SUDs, treatment typically involves a combination of different types of services to address the medical, behavioral and social needs of the patient and care is often delivered by specialized SUD treatment facilities. Despite recommendations for a broad suite of services, individual facilities vary in the specific services that they offer. This study examined whether and why systematic differences exist between treatment facilities based on their service mix and whether …


Understanding And Improving The Police Response To Suspected Cases Of Human Trafficking, Lekendra Kidd Jan 2021

Understanding And Improving The Police Response To Suspected Cases Of Human Trafficking, Lekendra Kidd

All ETDs from UAB

Human trafficking has been on the rise since slavery was abolished in the 19th century. As the prevalence of human trafficking continues to rise, the criminals involved continue to develop more sophisticated ways to hide their crimes from the police. Accordingly, countless victims remain unidentified. Research shows there is a critical need for local law enforcement officers to be trained in how to identify and investigate cases of human trafficking, as well as to interact compassionately with and effectively help its victims. The purpose of the current study was to qualitatively investigate the human trafficking training currently provided to local …


Destiny In The Details: Jacopo Zucchi's Ages As Ferdinando I De' Medici's Astrological Natal Chart, Molly Claire Kinstler Jan 2021

Destiny In The Details: Jacopo Zucchi's Ages As Ferdinando I De' Medici's Astrological Natal Chart, Molly Claire Kinstler

All ETDs from UAB

Jacopo Zucchi’s Age of Silver and Age of Gold, painted for Cardinal Ferdinando I de’ Medici in 1575, have been taken at face value as representations of two of the Ages of Man as described in Hesiod’s Theogony, Ovid’s Metamorphoses and Virgil’s Eclogues IV. In this thesis I argue that while these paintings utilize a traditional theme of the “Ages of Man,” long iterated by the Medici, they hold a deeper, inordinately complex narrative of Ferdinando I de’ Medici’s destined ascent to power as predicted by his astrological natal chart. Natal charts of the position of the planets at the …

Actual And Perceived Balance Abilities While Performing Tasks That Challenge Balance In Older Adults And Individuals With Parkinson's Disease., Jutaluk Kongsuk

All ETDs from UAB

Walking is a fundamental activity for one to interact effectively with one’s environment. Walking in the community often requires both a wide range and constant modification of walking speed. Decreased walking capacity, that is the maximum speed that a person can physically achieve, results in a decline in both functional mobility and personal independence, contributing to decreased community participation among individuals whose walking is impaired. The most common test of walking speed (i.e., overground comfortable and maximum walking speed) may not reflect the full capacity of individuals to regulate gait control. Whereas walking with progressively increasing treadmill speeds allows researchers …


Heads Or Tails? Structural Studies Of Host Interaction And Molecular Piracy In Bacteriophages, James Lewis Kizziah Jan 2021

Heads Or Tails? Structural Studies Of Host Interaction And Molecular Piracy In Bacteriophages, James Lewis Kizziah

All ETDs from UAB

Staphylococcus aureus is an opportunistic human pathogen dependent mainly on bacteriophages (phages) for dissemination of the virulence factors that contribute to its pathogenicity. Most phages have double-stranded DNA (dsDNA) genomes which are packaged into protein capsids attached to tails of varying morphology to form their complete virion structures. S. aureus pathogenicity islands (SaPIs) are highly specialized mobile genetic elements that encode various virulence factors and have been named molecular pirates for their ability to parasitize certain helper phages. SaPI1 is capable of hijacking virions constructed by the helper phage 80α, partly by altering the size of the capsid to only …


Gait Adaptability With Healthy Aging And Parkinson’S Disease, Daniel Kuhman Jan 2021

Gait Adaptability With Healthy Aging And Parkinson’S Disease, Daniel Kuhman

All ETDs from UAB

Human locomotion often occurs through environments with complex sets of external demands (e.g., obstacles, uneven surfaces, altered terrain, etc.). Fortunately, humans have developed locomotor systems capable of rapidly adapting gait patterns to navigate these environments. Advanced age and neurological disorders such as Parkinson’s disease (PD) are associated with physiological changes that add to the complexity of locomotion – these individuals must not only adapt to changing environmental demands, but also to changes in internal function (e.g., reduced muscle strength, dysfunctional sensorimotor integration). While there is a growing body of literature indicating that healthy older adults maintain adaptability, less is known …


Inducible T Cell Costimulator Stabilizes Regulatory T Cell Phenotype And Controls Host-Microbiota Interactions To Reduce Susceptibility To Intestinal Inflammation, Ashley Elizabeth Landuyt Jan 2021

Inducible T Cell Costimulator Stabilizes Regulatory T Cell Phenotype And Controls Host-Microbiota Interactions To Reduce Susceptibility To Intestinal Inflammation, Ashley Elizabeth Landuyt

All ETDs from UAB

Genome wide association studies (GWAS) have identified a loss-of-function mutation in the gene encoding inducible T cell costimulator ligand (ICOSL) as correlating with inflammatory bowel disease (IBD). The reason for this association was largely unknown. ICOS signals have been implicated in controlling the dynamics of regulatory T (Treg) cells, which are essential to intestinal homeostasis. Compared to WT mice, ICOS-deficient mice possessed fewer Treg cells in the colonic lamina propria (cLP). The deficit in ICOS-deficient Treg cell numbers was attributable to preferential loss of Foxp3 expression. Bisulfite sequencing revealed that ICOS-deficient Treg cells did not demethylate conserved noncoding sequence 2 …


The Association Between Medicaid Expansion, Medicaid Disproportionate Share Payments And The Financial Performance Of Safety Net Hospitals, Jon Law Jan 2021

The Association Between Medicaid Expansion, Medicaid Disproportionate Share Payments And The Financial Performance Of Safety Net Hospitals, Jon Law

All ETDs from UAB

Safety Net Hospitals (SNHs) provide necessary emergency and acute care to all individuals, regardless of their ability to pay for health care. Medicaid Expansion and Disproportionate Share (DSH) payments are two Medicaid programs that may mitigate the financial vulnerability of SNH’s. Some assert that Medicaid Expansion, as part of the Patient and Affordable Care Act (ACA), may provide financial relief for SNHs. It offers payment mechanisms for millions of uninsured individuals. DSH expenditures per capita for each state vary widely. There is some likelihood that SNHs in some states may benefit greater than others. The study was framed within the …
