Comparative Analysis Of Time Series Models On U.S. Stock And Exchange Rates: Bayesian Estimation Of Time Series Error Term Model Versus Machine Learning Approaches, Young Keun Yang

USF Tampa Graduate Theses and Dissertations

This study presents a comparative analysis of contemporary applications of time series models, focusing on the Bayesian approach. In contrast to many nonparametric studies, the Bayesian approach circumvents the common issue of bandwidth selection by offering systematic estimation and avoiding ad hoc methods. Specifically, we delve into the Bayesian approach for estimating the autocovariance function of a time series model’s error term. Traditional time series models often make the unrealistic assumption of a constant error term. Furthermore, models such as autoregressive conditional heteroskedasticity (ARCH) and general autoregressive conditional heteroskedasticity (GARCH) address the limitation of constant variance by assuming an autoregressive …

Study Of Hybrid Nanofluid Flow In A Stationary Cone-Disk System With Temperature-Dependent Fluid Properties, A. S. John, Mahanthesh Basavarajappa, G. Lorenzini

School of Mathematical & Statistical Sciences Faculty Publications

Cone-disk systems find frequent use such as conical diffusers, medical devices, various rheometric, and viscosimetry applications. In this study, we investigate the three-dimensional flow of a water-based Ag-MgO hybrid nanofluid in a static cone-disk system while considering temperature-dependent fluid properties. How the variable fluid properties affect the dynamics and heat transfer features is studied by Reynolds’s linearized model for variable viscosity and Chiam’s model for variable thermal conductivity. The single-phase nanofluid model is utilized to describe convective heat transfer in hybrid nanofluids, incorporating the experimental data. This model is developed as a coupled system of convective-diffusion equations, encompassing the conservation …

The Sacred And The Supernatural: Christianity And Teutonic Folklore In The Grimms’ Briar Rose, Amelia Stefanescu

Honors Theses

During the nineteenth century, the Brothers Grimm undertook the task of preserving German folklore during a time of cultural upheaval and struggle for national identity. One such tale, Briar Rose, emerges as a site of ideological interplay between Christian themes and Teutonic traditions. By analyzing the Grimms’ 1812 (first) and 1857 (last) editions, this thesis investigates how the text reflects and synthesizes these distinct belief systems into a coherent narrative.

The research explores how Christian and pagan elements co-exist within Briar Rose and what these interactions reveal about the cultural and religious dynamics within the folktale. The study argues that …

The Modular Generalized Springer Correspondence For The Symplectic Group, Joseph Dorta

LSU Doctoral Dissertations

The Modular Generalized Springer Correspondence (MGSC), as developed by Achar, Juteau, Henderson, and Riche, stands as a significant extension of the early groundwork laid by Lusztig's Springer Correspondence in characteristic zero which provided crucial insights into the representation theory of finite groups of Lie type. Building upon Lusztig's work, a generalized version of the Springer Correspondence was later formulated to encompass broader contexts.

In the realm of modular representation theory, Juteau's efforts gave rise to the Modular Springer Correspondence, offering a framework to explore the interplay between algebraic geometry and representation theory in positive characteristic. Achar, Juteau, Henderson, and Riche …

Profiling Of Voltage-Gated Sodium Channel Subtype Expression And Resulting Susceptibility To Targeted Osmotic Lysis In Cancer, Spencer Gerard Lemoine

LSU Doctoral Dissertations

Cancer is a disease characterized by a wide array of dysregulated cellular function, activity, and growth. At times, specific dysregulations associated with cancer can be exploited as avenues of potential treatment. The sodium handling mechanisms and their associated proteins in cancer have received closer attention recently closely as such a potential mechanism to exploit for treating advanced cancer. Some novel treatments aim to inhibit the expression or activity of these sodium handling proteins in an attempt to prevent the cancer from advancing or becoming more aggressive; however, such approaches have had limited success. Targeted osmotic lysis (TOL) is a new …

Threatened shark species are caught in large numbers by artisanal and commercial fisheries and traded globally. Monitoring both which shark species are caught and sold in fisheries, and the export of CITES-restricted products, are essential in reducing illegal fishing. Current methods for species identification rely on visual examination by experts or DNA barcoding techniques requiring specialist laboratory facilities and trained personnel. The need for specialist equipment and/or input from experts means many markets are currently not monitored. We have developed a paper-based Lab-on-A-Chip (LOC) to facilitate identification of three threatened and CITES-listed sharks, bigeye thresher (Alopias superciliosus), pelagic thresher (A. …

FRY-like transcription coactivator (FRYL) belongs to a Furry protein family that is evolutionarily conserved from yeast to humans. The functions of FRYL in mammals are largely unknown, and variants in FRYL have not previously been associated with a Mendelian disease. Here, we report fourteen individuals with heterozygous variants in FRYL who present with developmental delay, intellectual disability, dysmorphic features, and other congenital anomalies in multiple systems. The variants are confirmed de novo in all individuals except one. Human genetic data suggest that FRYL is intolerant to loss of function (LoF). We find that the fly FRYL ortholog, furry (fry), is …

Metabolic Potentation Of Antibiotic Lethality From Carbon Source Preference In P. Aeruginosa And S. Aureus, Pooja Parikh, Trent Moudler

Undergraduate Student Symposium

Antimicrobial resistance (AMR) is a growing public health concern with a dire need for new solutions. This problem has only been exacerbated in recent years due to the misuse of antibiotics and globalization. As new antibiotic drugs are costly and time-intensive, it is imperative to understand and study creative new ways to combat AMR. In both natural ecosystems and clinical infections, microorganisms seldom exist in isolation. Rather, they flourish within polymicrobial communities, presenting unique challenges for therapeutic interventions owing to elaborate inter-species interactions. Two such pathogens are Pseudomonas aeruginosa (PA) and Staphylococcus aureus (SA); bacteria commonly found in patients with …

Toxoplasma Gondii Seropositivity And Risky Behaviors In College-Age Adults, Roohika Rastogi

Undergraduate Student Symposium

Toxoplasma gondii is a prevalent parasite that has infected more than 40 million people in the USA. House cats and other felids serve as definitive hosts and acquire Toxoplasma by consuming infected prey and intermediate hosts (e.g. rodents). Toxoplasma is known to manipulate prey neurophysiology to enhance its transmission. For example, infected rodents exhibit changes in testosterone, vasopressin, and dopamine. These neurophysiological changes elicit remarkable changes in host behavior: Toxoplasma-infected rodents are more likely to frequent open spaces and are less responsive to normally aversive stimuli (e.g. cat urine). The manipulation of intermediate host neurophysiology and behavior observed in …
