Numerical Studies Of Entanglement Entropy In The Fredkin Spin Chain, Joshua Tyler Moore

Electronic Theses and Dissertations

In this dissertation, we present work on the entanglement properties of the Fredkin spin chain, a spin one-half chain with local three-body interactions. We focus on the development and use of Monte Carlo techniques to measure the entanglement entropy for bipartitions of the Fredkin spin chain.

In the first chapter, we formally develop an extension to existing Monte Carlo techniques to allow for the calculation of higher-order Rényi entanglement entropies using the replica trick. The method clarifies how multiple systems can be simulated in parallel to calculate the Rényi entanglement entropy at any order.

In the next chapter, we apply …

Postprocessing Gan-Generated Synthetic Time Series Using Dynamic Time Warping, Md Raisul Islam Roni

Electronic Theses and Dissertations

Generative Adversarial Networks (GANs) are a class of deep learning models capable of producing realistic synthetic data that preserve the statistical and temporal characteristics of real datasets. The DoppelGANger (DGAN) framework extends this approach to time series data by jointly modeling temporal dependencies and contextual metadata. However, synthetic sequences generated by GAN may show temporal misalignment, resulting in inconsistencies when compared with real data. This study presents a postprocessing framework based on Dynamic Time Warping (DTW) and its differentiable extension Soft-DTW to improve the temporal alignment of synthetic time series. The framework is evaluated using quantitative measures of alignment and …

Learning To Be Trauma-Informed: An Examination Of Individual-Level Factors Predicting Perceptions Of And Response To Trauma-Informed Practice Trainings, Kelly Daniel

Electronic Theses and Dissertations

Trauma is a substantial threat to public health. As such, significant effort has been exerted into developing interventions which mitigate the consequences of trauma. Trauma-informed practice (TIP) aims to alleviate the effects of trauma by building policies and practices focused on safety, trust, transparency, support, collaboration, and empowerment. This study investigated how individual-level factors, including readiness for organizational change, perceived benefit of TIP training, and personal trauma history affect one’s ability to apply a TIP lens in a sample (n =100) of members of a graduate-level college. Further, it explored if one’s perceptions of and response to trauma-informed practice training …

Assessing Post-Pandemic Engagement In The Supplemental Nutrition Program For Women, Infants, And Children (Wic) In Northeast Tennessee, Christen Minnick

Electronic Theses and Dissertations

Since 1974, the federal Supplemental Nutrition Program for Women, Infants, and Children (WIC) has provided healthy food resources, nutrition education, and provider referrals for families at risk for poor nutrition. Public health professionals have consistently presented evidence that WIC engagement reduces premature births and infant mortality, improves child health and development, and increases specialized care access for participants. While average monthly participation in WIC has increased since the program’s inception, trends indicate that only around half of eligible families have consistently engaged with the program since 2011. Research has linked declining WIC participation to administrative burden, citing learning, psychological, compliance, …

Educator Perceptions Of Mindfulness Education In Rural Elementary Schools In Tennessee, Mary C. Shepherd-Mcgown

Electronic Theses and Dissertations

The purpose of this phenomenological study was to examine educator perceptions of mindfulness instruction and the alignment of school policies in rural elementary schools in Tennessee. Despite growing interest in mindfulness in education, few studies have investigated how these practices are experienced and implemented within under-resourced, rural contexts.

Guided by Bandura’s Social Learning Theory (SLT) and framed conceptually by the Whole-School Mindfulness (WSM) model, the study explored how social, organizational, and policy factors influence the adoption of mindfulness practices. SLT provided a theoretical lens for understanding how educator behaviors are shaped through observation, modeling, and reinforcement, while the WSM framework …

Bud On The Ballot: A County-Level Analysis Of Citizen Support For Cannabis Legalization, Amelia G. Jennings

Electronic Theses and Dissertations

Cannabis research has often emphasized usage rates among certain groups of citizens, focusing mostly on demographic factors. A less studied topic within the cannabis literature pertains to the predictors of voting patterns of legalization referendums. Past research on this topic has examined states with similar characteristics, which calls into question the generalizability of results. The current study attempts to broaden the scope of knowledge in this area by partially replicating a previous study that explored county-level voting patterns, while also exploring the potential influence of the declining agricultural industry in predicting support for cannabis legalization. This was accomplished by analyzing …

Bias And The Writing Process In Adaptations And Retellings Of Mythology, Haley Sanderson

Electronic Theses and Dissertations

My thesis is an examination of how adaptations and retellings of mythology are written and affected by readership and reception of mythology. I compare American Gods by Neil Gaiman and The Penelopiad by Margaret Atwood and how they are written as adaptations and retellings of mythology. As seen in both novels, the presence of the mythological source material in adaptations and retellings of mythology is equally influenced by authors’ perception and the influence of readership. Approaching the ideological positions of Atwood and Gaiman through the similarities and differences of The Penelopiad and American Gods provides a deeper insight on the …

A Leslie System For A Demographic Simulation: From An Actuarial Point Of View, David Kings

Electronic Theses and Dissertations

This thesis develops a discrete stochastic linear systems interpretation of age–stage demographic evolution grounded in Leslie operators and realized in a discrete-event simulation implemented with salabim. The central claim is that one annual cycle of the simulation constitutes a cone-preserving, stochastic affine transformation on a high- dimensional population state vector indexed by age, sex, marital status, household type, employment, and education, and that the composition of yearly operators yields a random matrix product whose top Lyapunov exponent is the stochastic counterpart of the Perron–Frobenius growth rate (Caswell, 2001; Tuljapurkar, 1997)[1, 2]. The actuarial bridge is constructed by mapping simulated survival …

An Income Subsystem As A Discrete Stochastic Leslie System: A Simulation-Based Approach, Fahd Nii Okantah Cobblah

Electronic Theses and Dissertations

This thesis formulates the household-income engine of an integrated population sim- ulator as a Discrete Stochastic Leslie System (DSLS). The nonnegative state vector nt ∈ Rk + aggregates income, savings, debt, employment, and transfers. (Here, the subscript + denotes the positive cone, i.e., vectors with nonnegative components). Annual evolution is linear in state, stochastic in coefficients: nt+1 = Ttnt + εt, with Tt : Rk + → Rk + cone-preserving. Exogenous macro drivers (inflation, employment, tax, salary inflation, mortgage) are forecast via ARIMA; forecasts multiply entries of Tt, preserving linearity in expectation while introducing realistic temporal correlation. The discrete-event implemented …

Divergent Responses Of Branched-Chain And Straight-Chain Lipid Membranes To Butanol Stress Revealed By All-Atom Molecular Dynamics Simulations, Joshua Olaf Aggrey

Electronic Theses and Dissertations

Membrane integrity under chemical stress is critical to cellular survival and industrial microbial bioproduction, yet the molecular basis of bilayer resilience remains poorly understood. Using all-atom molecular dynamics simulation, we compare the effect of increasing concentrations of 1‑butanol on membranes composed of straight-chain (1,2-dipalmitoyl-sn-glycero-3-phosphocholine, DPPC) and branched-chain (1-anteiso-palmitoyl-2-palmitoyl-sn-glycero-3-phosphocholine, APPC) lipids, which differ in the point of attachment of a single methyl group. In the absence of butanol, both membranes exhibit well-ordered architectures consistent with experimental benchmarks; however, under increasing solvent stress, their behaviors diverge markedly. DPPC membranes display gradual thinning, modest area per lipid …

Exploring The Impacts Of Medical Invalidation On Postpartum Parents With Pcos, Shalini Venkat

Electronic Theses and Dissertations

Individuals with polycystic ovary syndrome (PCOS) face an increased risk of poor perinatal health, yet little is known about whether negative healthcare experiences contribute toward these outcomes. Patients with PCOS have reported experiencing invalidation by healthcare providers; however, the effects of these encounters in postpartum populations remain unclear. Using data from an online survey, the current study investigated whether PCOS status moderated the relationships between invalidating communication by healthcare providers, pregnancy and birth complications, postpartum depression, and postpartum anxiety. While experiences of invalidating communication by healthcare providers predicted worse perinatal health, those with PCOS solely experienced an increased risk of …

“War Is God” And “Unguessed Kinships”: Blood Meridian And Cormac Mccarthy’S “Border Tetralogy”, Seth Reeves

Electronic Theses and Dissertations

This thesis applies the metaphysics of philosopher Gilles Deleuze to Cormac McCarthy’s novel Blood Meridian, arguing that the novel initiates a thread of immanent subjectivity that unfolds throughout the Border Trilogy that follows it. Against a hierarchical metaphysics of transcendence, specifically an inverted Platonic Idealism, Blood Meridian dramatizes an immanent world of “optical democracy,” a prose style that levels the human and nonhuman and eludes subject and object categories. The kid’s autonomy from Judge Holden’s violent domination marks the truncated beginning of a Deleuzian subjectivity of becoming-other and immanent kinship. This incomplete gesture continues in the Border Trilogy, where …

Stars And Shapes: An Investigation Of Stripped Envelope Supernovae Structures Using Spectropolarimetry Observations And Hydrodynamic Models, Sabrina Desoto

Electronic Theses and Dissertations

Supernovae (SNe) are the energetic deaths of massive stars, dispersing heavy elements throughout the galaxies and shaping cosmic evolution across the universe. However, understanding the connections between the evolution of massive stars, their catastrophic demises, and the myriad of observed SNe, remains a fundamental challenge in astrophysics. My work aims to narrow this gap by integrating extensive observational data with advanced hydrodynamical simulations to better interpret SNe observations and understand the origin of their geometry. The observational component utilizes the largest spectropolarimetry dataset of stripped-envelope (SE) core-collapse supernovae (CCSNe) gathered by the SNSPOL project. Analyzing nine Type Ib and eleven …

Islamic Political Anti-Theology: A Discursive Practice Of Contingency Beyond Sovereign Politics, Jason Andrus

Electronic Theses and Dissertations

Contributing to the field of political theology from outside the European Christian tradition, this dissertation develops a description of the distinct logics that Islamic theology generates from its metaphysical assumptions. These logics in turn make possible a discourse of political anti-theology where politics operates through contingency rather than sovereignty. Political theology scholarship has excavated how modern politics derives from secularized Christian theological concepts—particularly transcendent sovereignty. This study demonstrates that Islamic theology's absolute insistence on divine transcendence (tawhid) produces something fundamentally different: a politics that renders sovereign authority conceptually impossible. I identify this discursive practice of political anti-theology through …

Mechanisms Of Correlated Neuronal Activity In The Globus Pallidus, Hamza Albawaliz

Electronic Theses and Dissertations

This thesis investigates the mechanisms of correlated neuronal activity in the globus pallidus externus (GPe), a key structure in the basal ganglia. Neuronal activity in the GPe is reportedly decorrelated in healthy subjects but can become highly correlated in Parkinson’s disease. However, high-density neuronal recordings in the GPe of healthy rats reveal a surprising degree of correlated activity. This raises the question of whether intrinsic properties or network connectivity alone can account for such patterns. To explore this, a computational model was developed in which GPe neurons are represented as coupled phase oscillators influenced by experimentally derived phase-response curves and …
