Minimal Error Functions On Irregular Subsets Of The Real Line, Robert Michael Dukes

Mathematics & Statistics ETDs

Chebyshev Polynomials, those that minimize the maximal error on a compact set, are one of the most practical tools for approximating smooth functions. The classical results are on the set [-1, 1]; in this paper, we extend to more complicated subsets of the real line. We demonstrate some classical results and then take the result from [2] on regular Parreau-Widom Sets and extend it to semi-regular sets, defined as sets whose regular part is closed. We introduce the Regularity Coefficient as a series formed by evaluating the Green’s Function at irregular points. This new machinery is applied to the lower …

Derivation Of Adjoint Based Error Estimates For Nonlinear Ordinary Differential Equations With Application To Multistage Sir Models With Demographics, Daniel Alcala

Mathematics & Statistics ETDs

Ordinary Differential Equations (ODEs) are central to the mathematical modeling of various real-world phenomena, from mechanical systems governed by Newton’s laws to epidemic dynamics described by SIR-type ODEs. Since many ODEs do not admit closed-form analytic solutions, we approximate them numerically (e.g., with Euler’s, Runge–Kutta, or other such methods). This raises the key question: How accurate are these numerical solutions? In particular, reliably estimating the error in some quantity of interest (QoI) at time T without having an exact solution is of great scientific interest.

The first main contribution of this thesis is the development and analysis of adjoint-based error …

Toward Simulating 2d Cell Surfaces In A Disk, Myriam Allred

Mathematics & Statistics ETDs

Certain evolution models of cell surfaces (treated in two-dimensions) involve the solution of the Helmholtz equation with jump conditions enforced on an immersed closed curve. This thesis presents a sparse, modal spectral method for solving such Helmholtz problems. The solution is required to be continuous across the curve, but with a jump discontinuity in the normal derivative proportional to the planar curvature. The method relies on classical Fourier-Chebyshev basis functions, with the application of modal Chebyshev integration matrices to achieve sparse, banded approximations of the Helmholtz equation. The method achieves spectral convergence, despite the inherent low regularity of the relevant …

Assessing The Ecological Drivers And Consequences Of Partial Migration In Hudson River Striped Bass Over Three Decades, Caitlin Egan Zimmer

Biology ETDs

Climate change and shifts in human land use have caused extensive impacts to the connectivity, structure, and resilience of aquatic populations. Partial migration (PM), where only some individuals from a population migrate while the rest remain resident, can mitigate population-level responses to environmental stressors. However, little is known of the underlying mechanisms promoting variation in migration and whether these shift over time. In the Hudson River Estuary, striped bass (Morone saxatilis) are known to exhibit anadromous PM behavior. Here, I measured carbon isotopes (δ¹³C) of essential amino acids in striped bass scales to determine variation in …

The Island Biogeography Of Mangrove-Dwelling Vertebrates: Isolation, Specialisation, And Extinction, Jian Xiong David Tan

Biology ETDs

Mangroves are highly dynamic ecosystems that are widely distributed across the coastlines of the tropics and subtropics. Despite their low plant diversity, mangroves host a disproportionately high number of terrestrial vertebrate taxa. However, mangrove specialists — taxa that only occur in mangrove habitats — exhibit a global distribution that is incongruous with the broader background distribution patterns of mangrove-associated fauna, exhibiting higher diversity in Australia and Southeast Asia. This dissertation therefore aims to assess how the diversity and distribution of mangrove specialist fauna may have been shaped by the historical biogeography of mangroves, and the effects of mangrove specialisation on …

Plant Reproductive Strategies Shift In Response To Restoration Using Beaver Dam Analogs, Laurel F. Martinez

Biology ETDs

As riparian communities become increasingly degraded, restoration treatments are being implemented in streams to recover ecosystem functions. In the Jemez Mountains, beaver dam analogs (BDAs) are used to restore degraded streams by connecting the floodplain and increasing the extent of anoxic soil conditions. These environmental disturbances are expected to alter how riparian plants recruit, particularly their allocation to seed-based and vegetative regeneration strategies. We investigated whether BDAs and associated changes in soil water filled pore space (WFPS) affected riparian plant recruitment. We investigated the number of flowering stems as a proxy for seed-based regeneration and rhizome length and mass as …

Ecoimmunology Of Dirty Physella Acuta Snails, Kevin Arthur Mcquirk

Biology ETDs

Research on Physella acuta, an invasive freshwater snail, reveals insights into its parasitology, fitness, and molecular biology. Morphological and molecular analyses revealed two distinct mitogenomic lineages, local (B) and invasive (A) strains of native P. acuta, both having comparable trematode infection rates, suggesting that the low infection rates observed from A in invaded regions result from "enemy release" rather than immune incompatibility. Fitness assessments showed that while lineages A and B performed similarly under laboratory conditions, rewilding experiments revealed significantly higher fitness in lineage A. Transcriptomic profiling supported these differences, with A snails showing greater immune-related gene expression and …

Single-Nuclei Multiomics Analysis Identifies Abnormal Cardiomyocytes In A Murine Model Of Cardiac Development., Riley Leonard, Yi Zhao, Steven Eliason, Kathy Zimmerman, Ariana Batz, Cathy J. Hatcher, Robert M Weiss, Mason Sweat, Xiao Li, Brad A Amendt

PCOM Scholarly Works

Transcription factors such as Tbx5, Gata4, Mef2c and Pitx2 are required during cardiac development, and in adult cardiac homeostasis. We demonstrate that the gene dosage and modulation of these factors are mediated in vivo by the miR-200 family. Inhibition of a single miR-200 family member within the cluster results in defects of the left ventricle and cardiomyocyte maturation during development. Inhibition of the entire miR-200 family results in a ventricular septal defect and embryonic lethality by embryonic day (E)16.5. Inhibition of each miR-200 family has distinct heart phenotypes in cell specific differentiation and maturation. snRNA-sequencing reveals an immature cardiomyocyte cell …

Nitrogen Fixation In Pampinifervens, A New Species-Rich Genus Of Aquificaceae That Inhabits A Wide Ph Range In Terrestrial Hot Springs., Marike Palmer, Nancy O. Nou, Lara A. Turello, Carolyn E. Power, John C. Ong, Jonathan K. Covington, Dengxun Lai, Xavier Mayali, Anna-Louise Reysenbach, Yan-Ling Qi, Jeremy A. Dodsworth, Yitai Liu, Multiple Additional Authors

Center for Life in Extreme Environments Publications

Members of the Aquificota play important roles in hydrogen, sulfur, and carbon cycles in geothermal systems as ubiquitous and abundant chemolithoautotrophs; however, their roles in the nitrogen cycle are poorly defined. Here, we show that Aquificaceae isolate T-2 from Tengchong, China, fixes nitrogen based on growth with dinitrogen as the sole nitrogen source and incorporation of N atoms when grown with N. We further show evidence that suggests its nitrogen fixation (nif) genes are transcribed in situ in a nearby spring. We propose the name Pampinifervens diazotrophicum gen. et sp. nov., with strain T-2 (= JCM 35475 = DSM 116324) …

A Data-Driven Approach To Time Series Forecasting And Clustering Of U.S. Regional Drug Overdose Mortality, Koshali Hamy Muthunama Gonnage

Mathematics & Statistics ETDs

The increasing rate of drug overdose deaths in the United States poses a critical public health challenge, particularly due to the surge in synthetic opioids and other high-risk substances. This study presents a data-driven framework that integrates time series forecasting and clustering techniques. Monthly mortality data for five key drug types: cocaine, fentanyl, heroin, methamphetamine, and oxycodone were analyzed using four time series forecasting models: ARIMA, ETS, TBATS, and NNAR. These models were evaluated using standard accuracy metrics RMSE, MAPE, and MAE to assess predictive performance. Signal decomposition approach based on Singular Value Decomposition and subspace modeling was employed to …

Improved Rational Approximations Of Pi, Nelson Carella

Publications and Research

The irrationality exponent of a real number α is defined by maximal value μ(α) ≥ 1 such that the inequality |p/q − α| < 1/qμ(α) is true for finitely many rational approxi- mations by relatively prime pairs p/q. The earliest result introduced the upper bound μ(π) ≤ 42 for the irrationality exponent of π. Subsequently, it was improved by many authors. The more recent result introduced the improved upper bound μ(π) ≤ 7.6063. This note introduces an improved irrationality exponent μ(π) ≤ 3. The optimal value is expected to be μ(π) = 2.

Spatial Ecology And Habitat Selection Of Eastern Pinesnakes: Case Study On The Importance Of Scale In Conservation Biology, Matthew Grisnik, Alan Jones, Rachel Brubaker, Andrew M. Grosse, Scott L. Parker

Biology

Species are in decline world-wide, driven by multiple factors including habitat fragmentation. Understanding the habitat selection processes of species in these fragmented landscapes has become a focus of ecological studies and is a major component of conservation plan development. However, understanding how landscape level processes influence patterns of habitat selection is often ignored. Here we assessed the influence of landscape level processes in the habitat selection of Eastern Pinesnakes, a species in decline, within a protected area in South Carolina, USA. Over the course of a year, we tracked 8 Eastern Pinesnakes within a small protected area. Snakes exhibited seasonal …

Investigating The Determinants Of Influenza Entry And Spread In Human Airway Cells Using Fluorescence Microscopy, Zijian Guo

McKelvey School of Engineering Graduate Student Theses & Dissertations

Influenza A virus (IAV) remains a significant global health challenge. IAV utilizes the receptor binding protein hemagglutinin (HA) and the receptor destroying protein neuraminidase (NA) to facilitate infection. The activities of these proteins affect multiple steps in IAV life cycle. However, it remains unclear how these IAV factors influence infection dynamics in the context of a complex cellular environment encountered in the respiratory tract. In this work, we use fluorescence microscopy and human airway epithelial cells to study influenza biology at the single-cell and single-virion level, revealing key insights into viral binding, entry, and spread. First, we focused on the …

• Social Media Use Among Undergraduate Women: Associations With Body Image, Disordered Eating, And Well-Being, Kirsten P. Peterson

Psychology ETDs

Though prior research has identified a range of negative impacts associated with social networking site/app (SNS) use, these effects vary and are often attributed to specific aspects of SNSs rather than time spent on them. The current study examined relations between SNS use and various psychological outcomes (i.e., body appreciation, body dissatisfaction, eating pathology, depression, and self-esteem) and how these may differ by platform, proportion of image-based content, image subjects, and passive (relative to active) use. Worse outcomes were anticipated for individuals who primarily used appearance-focused platforms and those with greater exposure to image-based content, self or celebrity images, and …

Cultural Risk And Protective Factors Associated With Sexual Assault Among Hispanic And Non-Hispanic White Women, Daisy Ramos

Psychology ETDs

There is a paucity of research on sexual assault among Hispanic college women. Existing studies indicate that Hispanic college women report similar mental health sequelae as non-Hispanic White women following a sexual assault; thus, factors that protect or increase their risk is an area worthy of further investigation. Latino cultural values, such as familism, may serve as a protective factor for sexual assault among Hispanic college women, while acculturation with mainstream culture may function as a risk factor. This study examined whether ethnicity moderated the effects of cultural protective and risk factors on sexual assault experiences among Hispanic and non-Hispanic …

Staff Education To Increase The Number Of Continuous Glucose Monitors (Cgms) Prescribed At An Adult Primary Care Clinic For Individuals With Type 2 Diabetes., Josephine Opara

Walden Dissertations and Doctoral Studies

This quality improvement project focused on increasing the use of continuous glucose monitors (CGMs) in primary care for patients with type 2 diabetes. Its goal was to enhance providers' ability to prescribe and manage CGMs effectively. A review of existing literature and a provider survey identified key barriers, such as limited time and insufficient provider education on CGMs. The survey emphasized educational needs related to initiating and prescribing CGMs. Educational materials, including a PowerPoint presentation on prescribing, monitoring, and management, were developed and shared with clinic staff. Consequently, CGM prescriptions increased over the three-month period. The project aimed to improve …

Some Corrections To The Record On Lemkin’S Early Years: The Evidence From Poland, Zachary Mazur

Genocide Studies and Prevention: An International Journal

This piece addresses some misunderstandings regarding Raphael Lemkin's early years in Poland, his influences and the development of his ideas. While discussing some of the extent published information, I point out what other archival documents from Poland and the League of Nations have to say about Lemkin's past. One of the main points is that Lemkin was an unreliable narrator on his own life, and this has caused confusion.

Arts & Literature: A Personal Reckoning: Taking Responsibility As A Perpetrator, Henry C. Theriault

Genocide Studies and Prevention: An International Journal

This autobiographical essay identifies three forces that shaped the author’s participation in the scholarly and political struggle against genocide and other mass violence and oppression. These include his status as the grandson of Armenian Genocide survivors, the fact that his father was killed in action in the US War of Aggression against Vietnam, and the bullying he experienced as a child and adolescent. It then pushes back against any sense of victimhood that has resulted from the combination of these forces, to recognize the author’s implication in perpetration of the US War of Aggression against Vietnam, which the author has …
