Analog Artificial Neurons And Digital Amplifiers: Challenging The Roles Of Analog And Digital Circuit Architectures In Modern Cmos Processes, Taylor S. Barton

Theses and Dissertations

As complimentary metal-oxide semiconductor (CMOS) technologies scale and field-effect transistor (FET) architectures change, the factors in deciding to utilize analog or digital transistor behaviors evolve. This thesis examines three case studies where traditionally analog or digital circuitry has dominated published works but I show that the opposite regime has significant benefits in scaled CMOS technologies. I present a highly digital operational amplifier (traditionally analog) and two artificial neurons (traditionally digital). In Chapters 2 and 3 I present a highly-digital five-stage zero-crossing-based amplifier which breaks the trade-off between slew rate and settling accuracy. I investigate the optimal charge pump design by …

Dynamic Regulation Of Store-Operated Calcium Entry By Protein S-Acylation, Goutham Kodakandla

Theses and Dissertations

Calcium plays a pivotal role in many physiological functions in cells. Cytosolic calcium levels are finely tuned by calcium ion channels, pumps, and intracellular organelles. Store-operated calcium entry (SOCE) is when depletion of endoplasmic reticulum (ER) calcium stores activates a calcium sensor known as stromal interaction molecule 1 (STIM1). Activation of STIM1 leads to a conformational change from a compact state to an extended state. This extended state of STIM1 allows it to bind to a calcium channel in the plasma membrane (PM) known as Orai1. The binding of Orai1 and STIM1 leads to opening of Orai1 channels and calcium …

A Definition Of Reliable Water Supply For Public Water Systems, Easton Hopkins

Theses and Dissertations

"Reliable water supply" does not have a universal definition in Utah, or the Western United States, where water resources are limited and such a definition would be especially useful. Utah's three water agencies and 500 public water systems have no consistent method to define, evaluate, and report it, potentially leading to an inability to meet regulatory water demands. We propose a unified definition of reliable water supply for Utah's public water suppliers that can also be used elsewhere. The qualitative definition we propose is necessary to precede quantitative evaluations, set policy, and provide consistency to water resources management in Utah. …

Nano Composite Piezo-Responsive Foam Enabled Pressure Mapping, Jake Duane Sundet

Theses and Dissertations

Pressure injuries cause pain both physically and financially. By creating a comfortable pressure mapping system, pressure injuries can more easily be prevented, and a large expenditure avoided. Nano composite piezo-responsive foam (NCPF) is an inexpensive foam that can be used to measure a static load while still providing a comfortable interface. As NCPF compresses, the impedance changes, correlating to a change in pressure. Optimizing electrode geometry is needed to take full advantage of the impedance change NCPF incurs upon deformation. To optimize electrode geometry, a design of experiment was performed which concluded that a one square inch area of interlaced …

Towards Critical Reflexivity In Gifted Education Teacher Preparation, Inna Kruvi

Theses and Dissertations

Ever since the emergence of gifted education in the United States in the beginning of the twentieth century, the concept of giftedness has been used to marginalize, segregate, and exclude students of particular backgrounds from specialized academic programs. Among the factors that contribute to unequal access to gifted education for ethnically, culturally, linguistically, and economically diverse (ECLED) students, teacher bias, deficit thinking, and insufficient teacher preparation have been identified as especially significant (Coleman et al., 2015; DeWet & Gubbins, 2011; Mansfield, 2015). Among various approaches to mitigate underrepresentation of ECLED students, the concept of cultural humility (Tervalon and Murray-Garcia, 1998) …

Sun Protection Behaviors And Skin Cancer Risk Among Children Of Color, Williana Magloire

Theses and Dissertations

Sun protection is beneficial for children of color as it decreases the risk for sunburns, hyperpigmentation, and most importantly, skin cancer. Invasive melanoma is commonly seen in children of color due to inadequate sun protection. Parental and caregiver modeling of sun protection behaviors may decrease the likelihood of skin cancer among children of color. The American Academy of Pediatrics (AAP, 2011) has suggested that pediatricians adopt the role of informing parents about the benefits of using sun protection products for their young children. They recommended that providers discuss sun protection behaviors with both the parent/child beginning at the age of …

Development Of Optimal Cut Scores For Within-Normal-Limits Mmpi-2-Rf Profiles Of Sex Offenders, Ilona Iikhtman

Theses and Dissertations

Alleged and convicted sex offenders are generally required to undergo forensic evaluations that frequently include a psychological assessment to answer a wide range of psycho-legal questions. A critical component of the psychological assessment of sex offenders is the evaluation of personality and psychopathology. The Minnesota Multiphasic Personality Inventory (MMPI) and its subsequent editions have been the most widely used personality assessment measures in forensic evaluations, including sex offender evaluations, and in research conducted with sex offenders. The previous literature demonstrates that a subgroup of sex offenders often produce test scores reflective of the general population, which is referred to as …

A Comparison Of Defensiveness In Mmpi-2-Rf Profiles Of Male Sex Offenders And Child Custody Litigants, Kyla M. Jones

Theses and Dissertations

Clinical evaluations have had a long-standing role in criminal and civil legal proceedings due to the intersection between various legal criteria and aspects of psychological functioning. The Minnesota Multiphasic Personality Inventory (MMPI; Hathaway & McKinley, 1943) and its subsequent versions have been among the most commonly utilized and empirically supported measures of personality and psychopathology in assessing forensic populations. One application for which MMPI instruments have been particularly useful is in the evaluation of sex offenders. This is in part due to the tests’ built-in validity scales, as MMPI underreporting scales are found to be effective in assessing sex offenders’ …

The Relationship Between Parental Trauma History And Perceptions Regarding Their Child’S Healthcare And Utilization Of Healthcare Services, Krishna Patel

Theses and Dissertations

Abstract

TITLE: The Relationship Between Parental Trauma History and Perceptions Regarding Their Child’s Healthcare and Utilization of Healthcare Services

Adverse child events (ACEs) have been associated with a number of physical and mental health problems and have also been linked to increased health care utilization. While parents who have an ACE history may tend to seek healthcare services for themselves, limited studies have examined the impact of their trauma history on seeking healthcare services for their child. Healthcare utilization may also depend on the parents’ level of health anxiety, as well as their anxiety about their child’s health status. This …

Getting Straight To The Point: A Bystander Training For College Students To Address Sexuality-And Gender-Specific Microaggressions In Schools, Caroline Signa

Theses and Dissertations

Research suggests that school climate is a critical component in a student’s sense of safety within a school and is the foundation for student-staff relationships. Despite this recognition, school staff demonstrate an insufficient intention to intervene on witnessed acts of gender- and sexuality-based inequity and grapple with discerning what these inequities look like (Kitzinger, 2005; Thapa et al., 2013). Some research has begun to target this gap in what intervention looks like, showing signs of positive effects on microaggression workshops increasing participant intention to intervene (Ackerman-Barger et al., 2021; Moors et al., 2022). I recruited 31 undergraduate students to participate …

The Moderating Effect Of Volunteer Motives On The Relation Between Job Demands And Exhaustion, Aaron Whitely

Theses and Dissertations

Developments in the burnout literature have shown that concepts such as a personality can function as job resources in a framework where resources buffer the relation between job demands and burnout. The present study looked at the concept of volunteer motivation as a job resource used to buffer the relation between job demands and exhaustion. With a sample of 338 volunteers from various volunteer organizations, this research examined the relation of motivation, broken into intrinsic and extrinsic motivation, and exhaustion. Both intrinsic and extrinsic motivation were negatively associated with exhaustion. Intrinsic motivation was found to interact with job demands such …

Navigating Complexity Of Serving Displaced Communities: A Study Of Yemeni Community-Based Organizations In Egypt, Alya Mohammed Al-Mahdi

Theses and Dissertations

Forced displacement is a global crisis that poses challenges for nations like Egypt. Despite international NGO support, escalating displaced individuals have overwhelmed existing capacities.

Characterization Of The Autoinhibition Mechanism Of The Heterotrimeric Kinesin-2 Motor Protein Kif3a / Kif3 B, Caleb Ayooluwa Sawe

Theses and Dissertations

Autoinhibition is a conserved mechanism regulating the motor proteins of the kinesin superfamily, which allows active motors to switch into an inactive state after cargo unloading. This regulation is generally believed to be an ATP conservation mechanism. Autoinhibition occurs when the motor molecule assumes a folded conformation in which the non-motor portions interact with, and thereby inhibit the activity of, the motor domains. This process is incompletely characterized in the heterotrimeric kinesin-2 motor (KIF3A/KIF3B), which is essential for mammalian anterograde intraflagellar transport and ciliogenesis. Furthermore, the physiological role that kinesin autoinhibition plays in cellular processes has only recently started to …

Changes In Rna Expression Of Hut78 Cells Resulting From The Hiv-1 Viral Protein R R77q Mutation, Joshua S. Ramsey

Theses and Dissertations

Human immunodeficiency virus type 1 (HIV-1) is the causative virus for acquired immunodeficiency syndrome (AIDS). AIDS is characterized by chronic inflammation and reduction of CD4+ T-cells in the blood. This leads to the patient becoming immunocompromised and much more susceptible to disease in general. Different phenotypes in the progression of AIDS have been observed in patients in either progressing to AIDS faster as a Rapid Progressor (RP), or slower as a Long-Term Non-Progressor (LTNP). Researching elements that result in the LTNP phenotype is of interest as it has the potential to offer alternative treatments and therapies to those suffering from …

Molecular Mechanisms Underlying Host Immunity In The Drosophila-Parasitoid System And Its Application In A Course-Based Research Experience, Ashley Waring-Sparks

Theses and Dissertations

A functional immune response is essential for the survival of all living organisms. The fruit fly Drosophila melanogaster is a well-established model for studying host immunity as well as metabolic regulation during an immune response. Fruit fly larvae, in nature, are commonly infected by parasitoid wasps whose survival is dependent on the successful parasitization of their host. The immune response that the fly elicits toward the wasp egg is a primitive yet effective process. I characterized the genes induced by a host during infection, identified metabolites present in a host during infection, investigated the role of Ab in the cellular …

"Unraveling Shame": Therapy Experiences Of Religious Sexual Minority College Students, Audrey Louise Parker

Theses and Dissertations

Sexual minority adolescents and adults experience higher rates of psychological risk factors and mental health disorders than their straight peers. As theorized by the minority stress model, this increased distress may be related to both external stressors (including discrimination and violence) and internal stressors (concealment, expectation of rejection, and internalized homonegativity). For some sexual minority individuals who also hold religious beliefs, conflict between their sexual orientation and religious beliefs may act as another stressor. Sexual minority adolescents and adults present to therapy at higher rates than their straight counterparts, and clients seeking help with religious and sexual conflict make up …

Structural Design And Synthesis Of Growth Factor Receptor Binding Protein 2 (Grb2) Stabilizing Small Molecule, Mahfuzul Hasan

Theses and Dissertations

The growth factor receptor tyrosine kinase (RTK) family is a potent inducer of cellular growth. Ligand binding to cognate receptors on plasma membrane induces receptor dimerization and activation, which in turn recruits intracellular molecules for downstream signal transduction. A key signaling pathway activated by growth factor (GF) receptors is the Ras signaling cascade that ultimately leads to cell proliferation. Activation of RTKs leads to the recruitment of adapter protein Grb2, which is constitutively bound to the mammalian homolog of drosophila son of sevenless (SOS), and a guanine exchange factor (GEF) for Ras. The recruitment of the Grb2-SOS complex by activated …
