Record of Lufty Baptist Church, 1836-1895 (Lufty Baptist Church, Smokemont, N.C.)
No full textThis digitized microfilm consists of a single volume of minutes from Lufty Baptist Church. This volume also contains the Articles of Faith and Articles of Decorum from when the church was founded in 1836. Later versions of these articles can also be found in this volume under the name "Duties of Church Members" as well as "Rules of Decorum" and "Bylaws." The minutes deal with the period from 1836 to 1895, giving an account of the church's meetings as recorded by the church clerk. These meetings were generally held on the Saturday preceding the fourth Sunday of the month and often dealt with obtaining contributions for church projects as well as ensuring adherence to the rules. Membership lists for 1874, 1886, 1894, and 1895 can also be found in this volume. These minutes suggest that the church devoted a great deal of energy to ensuring proper conduct
Advances in Tensor Decompositions: Fast Matrix Multiplication Algorithms and Parallel Adaptive Compression Techniques
No full textTensors are essential in modern-day computational and data sciences. This work presents recent advances in tensor decompositions, which are techniques that break down complex high-dimensional arrays into smaller structured components. There are two projects presented in this thesis, each with its own abstract and chapter.
Searching For Cyclic Invariant Fast Matrix Multiply Algorithms using the CP Decomposition: Fast matrix multiplication algorithms correspond to exact CP decompositions of tensors that encode matrix multiplication of fixed dimensions. This 3-way matrix multiplication tensor has cyclic symmetry: the entry values are invariant under cyclic permutation of the indices. The CP decomposition of Strassen's original fast matrix multiplication algorithm for 2x2 matrices is cyclic invariant, which means a cyclic permutation of the CP factors results in the same CP components, just in a different order. We describe how to search for cyclic invariant solutions using the damped Gauss-Newton optimization method along with heuristic rounding techniques. We not only summarize the algorithms discovered so far but also attempt to search for further symmetries in these algorithms by describing the requirements for an algorithms to admit such symmetries
Quantum Effects in Schwarzschild-de Sitter Spacetime and the Validity of the Semiclassical Approximation to Quantum Electrodynamics
No full textSemiclassical methods, such as those related to quantum electrodynamics or quantum field theory in curved spacetime, provide a means for exploring the interplay between quantum phenomena and classical background fields in regimes where a fully quantized theory is not required. This framework has been essential for exploring phenomena such as the Schwinger effect in strong electric fields, Hawking radiation from black holes, and particle production during inflationary scenarios.
The simplest type of semiclassical method is that of a background field approach in which a quantum field evolves in the presence of a background field that is unaffected by quantum processes. This approach is used to investigate properties of the symmetric two-point correlation function for a massless minimally coupled scalar field evaluated in the Unruh state for Schwarzschild-de Sitter spacetime in 3+1 dimensions. Schwarzschild-de Sitter spacetime is a solution to Einstein's equation corresponding to a black hole immersed in an expanding universe. The Unruh state is the state for an eternal black hole spacetime which best models Hawking radiation that occurs for a black hole that forms from collapse. A notable result, in certain cases, is that the two-point function exhibits unbounded linear growth with respect to time, indicative of an instability related to the Unruh state.
When quantum effects become significant, the background field is modified through backreaction effects. This can be accounted for using the semiclassical approximation in which the classical background field couples to the quantum expectation value of quantities such as the electric current constructed from quantum fields. The accuracy of the semiclassical approximation depends on the associated quantum fluctuations of the quantities under review. The validity of the semiclassical approximation to quantum electrodynamics in 1+1 dimensions is investigated for models in which particle production occurs due to a time-dependent electric field coupled to either a massive complex scalar field or a spin 1/2 field. A necessary, but not sufficient, criterion for the validity is used in the framework of linear response theory to assess the stability of the backreaction process to perturbations. The stability of solutions to the linear response equation depends on a two-point function for the electric current, which is taken to be measure of the strength of quantum fluctuations
Fact or fiction? Investigating self-other agreement on self-reported posttraumatic growth through the lens of romantic partners
No full textThis thesis examined the construct validity of the Stress-Related Growth Scale-Revised (SRGS-R; Boals & Schuler, 2018), a bidirectional measure designed to mitigate wording biases and demand characteristics inherent in traditional posttraumatic growth (PTG) assessments. Employing the largest dyadic sample in PTG corroboration research (N = 184 romantic couples), the study investigated self–other agreement on trait-level PTG and evaluated confidence as a moderator of this agreement using hierarchical regression analyses. Data was collected via online Qualtrics surveys administered through Prolific. Results indicated moderate trait-level agreement (r = .28, p < .001) between self-reports and informant ratings, suggesting that the SRGS-R may capture genuine PTG with greater accuracy than unidirectional measures reported in comparable studies (e.g., Blackie et al., 2015; Reynolds et al., 2022). Neither target nor informant confidence significantly moderated the self–informant relationship, and exploratory analyses of additional dispositional factors (e.g., intellectual humility, thoughtfulness) revealed no significant interaction effects. These findings provide preliminary evidence that a bidirectional assessment approach, combined with informant perspectives from intimate partners, may enhance the validity of PTG measurement. Implications for refining measurement tools and guiding future longitudinal research are discussed
INVESTIGATING THE IMPACT OF EXTRACELLULAR MATRIX STIFFNESS ON BREAST CANCER BEHAVIOR USING HIGH THROUGHPUT SCREENING PLATFORM
No full textTriple-negative breast cancer (TNBC) is an aggressive and heterogeneous subtype of breast cancer that lacks estrogen, progesterone, and HER2 receptors, making it particularly challenging to treat. The extracellular matrix (ECM) plays a crucial role in TNBC progression by modulating tumor stiffness, promoting metastasis, and influencing drug response. Traditional two-dimensional (2D) in vitro models fail to capture the complexity of the tumor microenvironment, necessitating the development of advanced three-dimensional (3D) models. In this study, we employ 3D bioprinting to fabricate cancer-stromal assembloids that mimic the TNBC microenvironment for high-throughput drug screening. Methacrylated hyaluronic acid (HAMA) is synthesized and characterized to provide a physiologically relevant ECM-like matrix. The platform integrates stromal cells to investigate their roles in tumor progression, invasion, and therapeutic response. The ability to recapitulate stromal interactions in a controlled 3D setting enables the study of critical factors driving TNBC metastasis and drug resistance. This model offers a scalable and reproducible approach for high-throughput screening applications, facilitating the discovery of targeted therapies for TNBC. By advancing biomimetic 3D cancer models, this study contributes to the development of more effective treatment strategies for aggressive breast cancers
Photoacoustic Imaging Assessment of Skeletal Muscle Oxygenation and Blood Perfusion with Doxorubicin-Induced Cardiotoxicity and Exercise Intervention
No full textDoxorubicin, a commonly used cancer chemotherapeutic agent, is cardiotoxic and causes deterioration in the left ventricle ejection fraction (LVEF) and fatigue. Exercise intervention has been suggested to ameliorate doxorubicin-induced cardiac decline, but further investigation of the relationship between doxorubicin, exercise intervention, LVEF, and fatigue is necessary. We implemented a mouse model of cancer treatment-induced cardiotoxicity across four animal cohorts: saline and sedentary (SAL SED), saline and exercise (SAL EX), doxorubicin and sedentary (DOX SED), and doxorubicin and exercise (DOX EX). The DOX SED cohort demonstrated a significant LVEF decline compared to the saline cohort controls while the DOX EX cohort ameliorated this decline. We conducted photoacoustic imaging on the skeletal muscle and found that skeletal muscle oxygen saturation in the DOX SED cohort significantly decreased compared to the saline cohorts. Skeletal muscle oxygen saturation in the DOX EX cohort did not significantly improve compared to the DOX SED cohort. Skeletal muscle total hemoglobin significantly increased in the DOX EX cohort compared to all the other cohorts. This study demonstrates that exercise intervention ameliorates doxorubicin-induced cardiotoxicity, and that more needs to be investigated about exercise intervention and chemotherapy-induced skeletal muscle wasting, fatigue, and changes in blood perfusion
INDIVIDUAL-LEVEL DETERMINANTS AND CLINICAL OUTCOMES OF HEAD ACCELERATION EVENT EXPOSURE IN YOUTH ICE HOCKEY
No full textIce hockey is an increasingly popular collision sport, with almost 1 million participants under the age of 20 across the globe. Boys’ and men’s ice hockey is characterized by body checking, intentional player-to-player collisions that aim to disrupt an opponent’s control of the puck. Concussion has been a long-standing concern in ice hockey, though most player-to-player contact does not result in diagnosable injury. However, an increasing number of studies in ice hockey and other contact and collision sports have reported a relationship between repetitive head acceleration event (HAE) exposure and negative health outcomes, both acutely and later in life. A wide body of work has investigated environmental and gameplay features of ice hockey contributing to HAE exposure, but it is less well-understood how intrinsic factors influence athletes’ HAE frequency or magnitude. The limited insight into individual-level determinants of ice hockey HAE exposure and still-developing understanding of HAE exposure’s role on clinical outcomes necessitates a need for additional study. Better understanding of determinants and outcomes of HAE exposure will facilitate opportunities for interventions to reduce exposure and improve ice hockey safety. This dissertation aims to evaluate individual-level preseason physical performance as a potential determinant of HAE exposure and to characterize temporal change in measures of neurobehavioral health as outcomes of HAE exposure among a sample of boys’ youth ice hockey athletes. Findings may add to a growing body of literature on determinants and clinical outcomes of HAE exposure, driving future interventions to reduce exposure and mitigate risk of negative health outcomes associated with contact and collision sport participation.This research is comprised of three parts:
1. Part 1 investigates individual-level physical performance as a novel determinant of ice hockey HAE exposure among a sample of boys’ youth ice hockey athletes.
2. Part 2 evaluates relationships between ice hockey HAE exposure and postural control outcomes and compares postural control between ice hockey athletes and a group of age-matched non-contact sport athlete controls.
3. Part 3 assesses relationships between ice hockey HAE exposure and another measure of neurobehavioral health – neurocognition; temporal changes in neurocognition were additionally assessed between ice hockey and control groups
