DIR and RIR methods were used to quantify the MAM. The registration accuracy was compared using Dice similarity coefficient (DSC). …

Peat Fires And Legacy Toxic Metal Release: An Integrative Biogeochemical And Ecohydrological Conceptual Framework, Colin P.R. Mccarter, Gareth D. Clay, Sophie L. Wilkinson, Gabriel Sigmund, Scott J. Davidson, Muh Taufik, Susan Page, Emma L. Shuttleworth, David Mclagan, Grant Chenier, Alexandra Clark, James M. Waddington

School of Geography, Earth and Environmental Sciences

Peatlands are potent landscape sinks of natural and industrial toxic metals and metalloids (TMMs) but the long-term sequestration of TMMs in peatlands is at increasing risk due to climate change enhanced peatland fires. The ability of peatlands to retain TMMs results from a host of interacting hydrological, biological, geomorphological, and chemical feedbacks, which underpin peatland functionality in general. Fire is a transformative force that often disrupts these interactions and feedbacks, leading to the potential release of TMMs to our air, land, and water. Given that wildfire burned area and severity are increasing there is a need for a conceptual understanding …

Predicting Gypsy Moth Population Size In Porcupine Mountains Wilderness State Park Using A Satellite Disturbance Index, Jonathan B. Thayn, Courtney M. Ballard, Emily L. Eichholzer, Michael J. Genard, Jordan A. Hawks, John P. Richard

The Geographical Bulletin

The pattern of gypsy moth defoliation in the Apostle Islands suggests that moths arrived first to the most isolated islands, not those that are nearest the mainland or the most visited by tourists. Gypsy moths are primarily wind-dispersed, so at least some of the moths may have been blown across Lake Superior. The Porcupine Mountains, about 55 km away, are a potential source for these moths. We used a satellite image-based disturbance index to map the extent of defoliation in and around Porcupine Mountains Wilderness State Park. Using these data and moth trap data provided by the Slow the Spread …

Relationship Of Flood Peaks To 24-Hour Rainfall In The Eastern Texas Hill Country, South-Central Texas, Richard A. Earl, Jeanett Bosarge, Heather Wooten, Sarita Hedgepeth, Joel Sherrouse

The Geographical Bulletin

The eastern Texas Hill Country is noted for its extreme storm rainfall amounts and the resulting flood discharges. The resulting flash f loods contribute to Texas leading the U.S. in automobile-related, flood fatalities. These f loods produce considerable groundwater recharge to the Edwards Aquifer. A better knowledge of relations between precipitation and peak flood discharges can improve f lood hazard warning and provide estimates of groundwater recharge from ungauged ephemeral streams. The purpose of this study was to analyze the relationship between 24-hour precipitation amounts and peak discharge for four ephemeral streams, with drainage areas between 0.3 to 18.8 mi.2 …

Exotic Construction Of An Ancient Oriental Sappho: On Rexroth’S Creative Translation Of Li Ch’Ing-Chao’S Ci-Poems And Its Influences, Yuqun Fu

CLCWeb: Comparative Literature and Culture

In her article “Exotic Construction of an Ancient Oriental Sappho: On Rexroth’s Creative Translation of Li Ch’ing-Chao’s Ci-Poems and its Influences,” Yuqun Fu discusses Li Ch’ing-Chao’s Ci-poems and her identity as a woman intellect in the patriarchal and feudal Song Dynasty of China. Due to Kenneth Rexroth’s feminist perspective and Sappho complex as well as his own pursuit to excel in the hipster stylistics of the newly prospering Beat writers, Rexroth turns to the Eastern women poets to fuel his own cause, especially in his idiosyncratic way of interpreting and translating Li Ch’ing-Chao. His translation focuses on gender identity and …

The Female Best-Friend Novel: Narration And The Reconsideration Of The Political Act, Neta Stahl

CLCWeb: Comparative Literature and Culture

In her article “The Female Best-Friend Novel: Narration and the Reconsideration of the Political Act,” Neta Stahl argues that twentieth- and twenty-first-century women novelists borrowed the eighteenth- and nineteenth-century best-friend narrative, reintroducing it for the purpose of challenging the very concept of the political act, namely, what modern, liberal society considers as a political action and what stands behind it. The article focuses on four novels written by novelists from four different countries: the American novelist Toni Morrison’s Sula (1973); the Israeli novelist Ronit Matalon’s Sarah, Sarah (2000); the Italian novelist Elena Ferrante’s L’amica geniale: Storia di chi fugge e …

Multi-Label Classification Using Conformal Prediction, Chhavi Tyagi

Dissertations

In many machine learning applications, such as image tagging, document classi-fication, and medical diagnosis, a data instance can be associated with multiple classes in parallel so that each instance is associated with multiple response variables simultaneously defining multi-label classification. Standard multi-label classification methods that provide point predictions have been developed. They lack in quantifying the uncertainty of predictions. These methods also lack in accounting for label dependencies and are very computationally expensive. This dissertation develops two methods of multi-label classification using conformal prediction that quantify the uncertainty of predictions. Chapter 1 introduces notations and tools that have been used in …

Investigating The Neurovascular Correlates Of Cognitive Function In Individuals With Spinal Cord Injury Using Functional Near-Infrared Spectroscopy, Donna Yali Chen

Dissertations

Individuals with spinal cord injury (SCI) have a 13 times greater risk of cognitive impairment than able-bodied individuals and commonly report symptoms of depression and anxiety. The reports of cognitive impairment in individuals with SCI are independent of concomitant brain injury. Although the direct cause of cognitive impairment in individuals with SCI is unknown, key contributors may include comorbid depression, chronic pain, anxiety, fatigue, brain injury, or cardiovascular dysfunction. Previous studies have focused on SCI at the level of the spinal cord but have under-investigated the supraspinal levels. Due to the lack of neuroimaging studies on SCI rehabilitation, it is …

Certifying Stability In Runge-Kutta Schemes: Algebraic Conditions And Semidefinite Programming, Austin Juhl

Dissertations

Numerical stability is a critical property for a time-integration scheme. In the context of Runge-Kutta methods applied to stiff differential equations, A-stability is one of the most basic and practically important notions of stability. Dating back to the work of Dahlquist, it has been known that A-stability is equivalent to the Runge-Kutta stability function satisfying a particular convex feasibility problem. Specifically, up to a transformation, the stability function lies in the convex cone of positive functions. In recent years, sum-of-squares optimization and semidefinite programming have become valuable tools in developing rigorous certificates of stability in dynamical systems. Therefore, it is …

Electrified membrane filtration presents a robust alternative, utilizing minimal or no chemical additives and harnessing electrical power to directly reduce contaminants or produce reactive oxidants or reductants on-site.

This dissertation is dedicated to the development of innovative electrochemically reactive membranes designed to address three major challenges: (1) the engineering of electrocatalysts with …

A Methodological Framework For Ontology Development, Enrichment, And Application In Natural Language Processing Tasks, Navya Martin Kollapally

Dissertations

Electronic Health Records (EHRs) have been widely used in healthcare to record demographics, vital signs, test results, immunizations, medical imaging reports, differential diagnoses, etc. It is now accepted that non-clinical (e.g., social) factors have a substantial influence on health outcomes. Hence, it is desirable to record these Social and Commercial Determinants of Health (SDoH & CDoH) in an EHR. The "non-text parts" of EHR notes (e.g., data tables) rely on coded terms from underlying ontologies or terminologies to facilitate semantic interoperability. Ontologies help define concepts, the relationships between them, and instances that can be utilized in research.

The first accomplishment …

Large Deviation Theory In Stochastic Processes: Applications To Biological Modeling, Moshe C. Silverstein

Dissertations

This dissertation delves into developing and applying stochastic models to analyze complex biological systems. It leverages Large Deviation Theory (LDT) to gain insights into these systems, focusing on two key examples: neural networks and calcium signaling dynamics. Traditional deterministic methods frequently fail to capture biological processes' randomness and inherent variability. Meanwhile, many stochastic approaches struggle to be mathematically tractable or provide accessible insights. The approach introduced in this study provides rigorous mathematical frameworks to enhance understanding of these stochastic behaviors while remaining tractable and insightful.

A stochastic model for a random biological neural network is constructed that addresses the dependencies …

Settling Dust, Unsettling Ground, Olivia Newroz

Masters Theses

Understanding dust as a material system that blurs the line between ground and atmosphere, I developed a dust machine as a tool for making dust legible at the human scale. While the blurriness of ground is visualized at both particle and planetary scales, at the human scale, it becomes less evident. Drawing from Lisa’s Moffitt’s discussion of “environmental models”–that is, models that don’t merely simulate phenomena, in this case dust, but rather produce the underlying force itself––I produced visualizations of how dust, as both a grounded and atmospheric element, intertwines ground and weather across scales, through a cyclical process of …
