Simulations Of Perpendicular Electron Holes, James Patrick Mcclung

Doctoral Dissertations

Bernstein–Greene–Kruskal modes commonly manifest as electron holes and electrostatic solitary waves in space plasmas. These Debye-scale structures are nonlinear solutions to the steady-state Vlasov–Poisson system. Solutions in one dimension are highly tractable mathematically, observationally, and computationally, and are relatively well-understood. Higher-dimensional, magnetized plasmas are less amenable to study, however. Following a 20-year history of theoretical developments in two-dimensional BGK modes, this thesis presents the first high-resolution 2D and 3D simulations thereof. Stability conditions and phase-space dynamics are discovered and discussed. The simulated modes are ultimately compared to observed electron holes and modern width-amplitude relations. In addition, a significant portion of …

Computational String Theory Using Machine Learning, Giorgi Butbaia

Doctoral Dissertations

Low-energy couplings of certain superstring theories are related to the masses of the particles. One of the most promising superstring theories is $\mathcal{N}=1$ supersymmetric $E_8\times E_8$ heterotic string theory. In a certain embedding of the standard model into $E_8\times E_8$ gauge group of the heterotic string, the particle spectrum consists of $(\mathbf{27})^3$, $(\overline{\mathbf{27}})^3$, $(\mathbf{1})^3$ and $\mathbf{1}\cdot \mathbf{27}\cdot\overline{\mathbf{27}}$ couplings. While the $(\overline{\mathbf{27}})^3$ couplings are quasi-topological, the $(\mathbf{27})^3$ explicitly depend on the Ricci-flat metric on Calabi-Yau.

In this dissertation, we explore recently developed techniques for calculating the normalized Yukawa couplings on various Calabi-Yau manifolds. In Chapter 2, we describe a novel architecture, …

Counting Kelp: Development And Assessment Of Modelling Approaches To Improve Understanding Of Kelp Bed Abundance And Resilience In The Gulf Of Maine, Constance N. Tyler

Doctoral Dissertations

Kelp habitats in the Gulf of Maine are threatened by rising ocean temperatures and marine invasions. The replacement of kelps with red turf macroalgae fundamentally alters these habitats and disrupts the ecosystem services they provide. Thorough assessment and monitoring of kelp habitats is needed for proper conservation of these habitats, but most long-term monitoring is performed using traditional survey methods that are restricted in the amount of space they can cover. Habitat modelling approaches are required to expand our knowledge of Gulf of Maine kelp habitats, and to better understand the interactions between kelp and red turf habitats across the …

The Assessment Of Language, The Language Of Assessment: Understanding How Language Teachers Support Dynamic, Communicative Language Learning Through Assessment, Rebecca Kelley

Doctoral Dissertations

As language classrooms in K-12 schools in the United States seek to promote students’ proficiency in the language they teach and to prepare students for a multilingual world, the role of assessment in these classrooms is often overlooked. This study draws from theories of formative and dynamic assessment, as well as a socially-constructed view of language and language learning, in order to examine the way in which secondary language teachers plan for, elicit, interpret, and use evidence from classroom assessments in such a way that promotes and supports the language learning happening in the classroom. Through a series of three …

Resolving The Role Of Wave-Induced Pressure Gradients On The Movement Of Sediments In Nearshore Environments, Melissa Marry

Doctoral Dissertations

Characterizing the hydrodynamic forces responsible for the initiation of sediment motion is fundamental for improved understanding of large-scale sediment transport processes in nearshore environments. Traditional sediment transport models assume incipient sediment motion is only driven by the force applied by bed stress (Bagnold, 1966; Shields, 1936) while more recent work has shown that incipient motion is influenced by the forcing of the horizontal pressure gradient due to surface gravity waves (Foster et al., 2006; Frank et al., 2015; Sleath, 1999). Wave-induced vertical pressure gradients can also destabilize the sediment bed through the process of momentary liquefaction (Florence et al., 2022b; …

Technologies To Support Remote Work For Collaborative Groups, Alberta Ansah

Doctoral Dissertations

The nature of work continues to evolve, particularly in the aftermath of the COVID-19 pandemic. While a substantial number of employees have returned to traditional, in-person work environments, many continue to engage in remote or hybrid work arrangements. Online meetings are a significant aspect of remote work, and while there has been a significant increase in this area, there are still aspects of these meetings that are not fully understood. Existing research in this area has primarily focused on the development of tools to facilitate meeting execution and content management. In contrast, relatively few studies have explored the social dynamics …

Eastern Oyster, Crassostrea Virginica, Genomics In A Well-Mixed Estuarine System: Examining Population Structure, Viability, And Response To Stressors, Alyssa Strickland

Doctoral Dissertations

Eastern oysters, Crassostrea virginica, are foundational estuarine species that contribute to a variety of ecosystem services including water filtration, nutrient cycling, habitat creation, and shoreline protection. However, populations have declined due to disease, overharvesting, habitat loss, and climate change, especially in northern systems such as New Hampshire’s Great Bay Estuary (GBE), located in the Gulf of Maine, one of the world’s fastest warming waters. This dissertation uses genomic and transcriptomic approaches to understand the drivers of population structure, decline, and resilience in GBE oyster populations, aiming to aid restoration and aquaculture. Chapter 1 used low-coverage whole-genome sequencing to understand population …

Uncovering The Plant-Microbe-Permafrost Paradigm As It Relates To Soil Priming And Arctic Carbon Cycles, Sean Robert Schaefer

Doctoral Dissertations

Permafrost, or perennially frozen soil, covers approximately 25% of the northern hemisphere and contains over half of the world’s soil organic carbon stocks. Permafrost-affected regions are rapidly warming, resulting in ecosystem changes including permafrost thaw and a shift from sedge-dominated to shrub-dominated plant communities. As permafrost thaws, it releases previously unavailable compounds to plants and microorganisms. Plant root inputs can then stimulate the decomposition of thawed permafrost, increasing greenhouse gas emissions in a process called priming. Permafrost thaw increases the decomposition of previously frozen soil organic matter (SOM); however, the extent of decomposition is highly dependent on plants and their …

Addressing Economic Valuation Issues Of Outdoor Recreation: Case Studies Of Lake Michigan Invasive Carp And Plum Island Visits, Iris Tryfoni

Doctoral Dissertations

Environmental valuation is the process of assigning monetary value on environmental goods and services, which do not easily have market prices. It is, however, possible to over- or underestimate the economic valuation of outdoor recreation issues, specifically (1) recreational fishing and (2) beach recreation. Despite their different focuses, both case studies share a common objective of refining methodologies to better understand and address complex environmental issues from an economic perspective. Traditional recreation valuation techniques often lack explicit connection to ecology, which can be impacted by various factors. Addressing this gap, in the first part of my dissertation, I propose a …

Long-Term Patterns In The Relative Abundance Of Common Snook As A Factor Of Shifting Environmental Conditions In The Florida Coastal Everglades, Jordan A. Massie, Ryan J. Rezek, Rolando O. Santos, W. Ryan James, Natasha M. Viadero, Ross E. Boucek, Jennifer S. Rehage

Marine Science

Objective Environmental variability as a factor of climate change and water management can result in fluctuations in the abundance and distribution of fish populations from year to year, with either negative or positive effects depending on behavioral and physiological requirements and the ability to adapt to changing conditions. Variability in water levels can also influence prey availability, affecting predator abundance in seasonal foraging areas. In this study, our objective was to better understand how environmental variation has affected the relative abundance of Common Snook Centropomus undecimalis in the freshwater/estuarine habitats of Everglades National Park. Methods Electrofishing data over 17 years …

Linking Hydrology, Temperature, And Energetics: Global Change Implications For The Foraging Ecology Of A Generalist Predator, Mack White, W. Ryan James, Justin S. Lesser, Ryan J. Rezek, Jonathan R. Rodemann, Ross E. Boucek, Rolando O. Santos, Jennifer S. Rehage

Marine Science

Objective: The objective of this study was to quantify the effects of temperature, hydrology, and body size on the diet and energy requirements of a generalist predator, Common Snook Centropomus undecimalis (hereafter, “snook”), to gain a better understanding of predator–prey dynamics in the wake of global change. We first ask how temperature, hydrology, and body size influence the occurrence of fish, invertebrates, and empty stomachs in the diet of snook. Next, we model the energetic requirements of snook as a function of body size and temperature. Last, we use predation simulations to test how changes in prey quality, together with …

Phishing Hunter: Phishing Domain Detection System, Connor Tess

Master's Theses and Capstones

Phishing domains are a common and effective attack vector that malicious actors use to fool users into believing that they are going to a trusted website in the hopes of compromising users. These attacks can also be referred to as phishing attacks because the domain in which malicious attackers act has a hook to trick users into going to the domain that users believe is legitimate. These malicious actors mislead users into believing they are visiting the intended site, when in reality they have been led to a website hosted by the actors. The purpose of this paper is to …

Applications Of Urban Forestry: Advancing Environmental Justice Via Tree Planting In New York City, Newell Alexandra Blanton

Student Theses 2015-Present

NYC’s urban forest is composed of 7 million trees and the infrastructure which supports them. These trees have incredible value in almost every sense of the word; they provide essential ecosystem services such as climate modification and air purification that are otherwise impossible or enormously costly to manage. Contrarily, a lack of tree coverage in an urbanized area can contribute negatively to the health, economics, and overall quality of life for a neighborhood’s residents. This paper analyzes the impact trees have in New York City through a socioeconomic lens by comparing tree metrics and their collective influence in various neighborhoods, …

Intellectual Risk-Taking And Emotional Intelligence In Educational Systems: A Comparative Study Of The Usa, Finland, Japan, And Singapore, Peter Hecht

Comparative Civilizations Review

This paper examines how intellectual risk-taking (IRT) and emotional intelligence (EI) are integrated into educational systems in the United States, Finland, Japan, and Singapore, arguing that these factors are essential for fostering creativity, resilience, and academic success. In modern pedagogy, IRT is defined as the willingness of students to engage in challenging academic tasks despite potential failure, thereby promoting innovative problem-solving and critical thinking (Beghetto 210; Dweck 6). Complementarily, EI — an individual’s capacity to recognize, understand, and manage emotions — plays a crucial role in classroom dynamics by enhancing self-regulation and interpersonal relationships (Goleman 43; Mayer et al. 197). …
