The Tongue Schizochronick: Linguistic Archaism In Thomas Pynchon's Mason & Dixon, Timothy Perry O'Connor

Masters Theses

In Thomas Pynchon's novel Mason & Dixon, Reverend Wicks Cherrycoke regales his family with tales of the titular pair. The novel is written in a pastiche of late-Enlightenment-era English, which expresses an attack on modernity. Modernity, according to Pynchon, explores entropy and excludes Christ. Subjunctivity and storytelling provide a way to make contact once again with a more hopeful paradigm. The novel joins premodernity and postmodernity through its language's aurality, variability, and polysemy. The pastiche serves to undermine modernity's ambitions by satirically embracing archaic language; adopting Enlightenment parlance gestures ironically at the outmodedness the era's -theorized progress. Aurality appears in …

Conservation Genomic Investigation Of A Threatened Trout Species Endemic To The Gila River, David Thomas Camak

Biology ETDs

Climate change is a looming threat to the persistence of species, especially aquatic, imperiled species. Species native to desert streams are at a particular disadvantage, as many species already face drought, floods, wildfires, and threats from nonnative species, all of which are thought to be exacerbated by climate change. Species such as the threatened Gila Trout (Oncorhynchus gilae) already have small ranges and persist in fragmented and isolated habitats that limits gene flow between populations. Therefore, it is important to understand the current genomic status of such populations to be able to predict the future effects of climate …

The well-exposed basement transect in the Lower Granite Gorge (LGG) of western Grand Canyon provides a middle-crustal record of suturing crustal blocks during the Proterozoic accretionary history of southwestern Laurentia. Orogenic evolution included at least three stages: (1) subduction-related ~1.75-1.72 Ga volcanic arc magmatism, turbidite deposition, and suturing of arc terranes with different crustal thicknesses; (2) intense northwest-southeast crustal shortening at ca. 1.71-1.68 Ga to form the Vishnu Mountains during the Yavapai orogeny; (3) dextral strike-slip shear zones development at ~1.4 Ga during long-term crustal residence and slow cooling above ~250 °C (~10 km) until ~1.3 Ga. Final cooling from …

Theoretical And Spectroscopic Insights Into Molybdenum- And Tungsten-Sulfur Bonding, Jesse Lepluart

Chemistry and Chemical Biology ETDs

Molybdenum and tungsten chemistry in biology is dominated by bonding interactions with sulfur and the other chalcogens. The highly-conserved structures of these enzymes’ active sites suggest an early evolution in the history of life, with molybdenum and/or tungsten enzymes likely expressed by the last universal common ancestor. Despite their active site similarities, molybdenum and tungsten enzymes catalyze a diverse array of reactions via equally diverse mechanisms. A deep understanding of the electronic structures of these enzyme active sites and their catalytic intermediates is key to understanding this remarkable chemistry.

The work presented here aims to deepen the understanding of molybdenum …

Sulfur Sequestration In Anhydrite Through Alteration Of Calcic Wall Rock, Lexi Kenis

Earth and Planetary Sciences ETDs

Heterogeneous gas-solid reactions are suggested as a potential mecha-
nism for sequestering gaseous sulfur through the alteration of calcic wall
rocks. This study explores the concept of a “hierarchy of reactions” pro-
posed by Giggenbach (1987), outlining the interplay between gas components
and redox-related minerals in volcanic wall rocks. Mt. Pinatubo provides a
more felsic composition and more oxidizing conditions compared to previ-
ously studied volcanoes, Kudryavy and Erta Ale (Henley and Fischer, 2021),

thermodynamic models and synthetic melt experiments, evaluations of effi-
ciency of sulfur sequestration across …

Coupled Monte Carlo And Adjoint Depletion Sensitivity Coefficient Methods, Benjamin R. Murphy

Nuclear Engineering ETDs

Recent advances in adjoint-based, continuous-energy Monte Carlo generalized perturbation theory (GPT) sensitivity coefficients are combined with adjoint-based depletion perturbation theory (DPT) sensitivities to obtain fully coupled depletion sensitivity coefficients in OpenMC. These depletion sensitivity coefficients are compared with direct perturbation results and found to have generally good agreement, though discrepancies exist. Some shortfalls of the DPT method include the inefficient initial numeric integration scheme for calculating the DPT sensitivities and the lack of stochastic uncertainty estimates for the DPT sensitivities. However, despite these shortcomings, the methodology provides the means to obtain high fidelity depletion sensitivity coefficients. With refinements to the …

Parallel Multigrid In Time For Chaotic Dynamical Systems, David Alan Vargas

Mathematics & Statistics ETDs

Despite the fact that Parallel-in-Time (PinT) methods are predicted to become necessary to fully utilize next-generation exa- and zettascale machines, there are currently no known practical methods which scale well with the length of the time-domain for chaotic problems, due to exponential dependence of the condition number on the fastest chaotic timescale. I present modifications to the coarse-grid equations along with a novel rediscretization approach which together greatly improve convergence of the multigrid reduction in time (MGRIT) algorithm and allow the first known PinT speedup for a chaotic PDE. The novel Local Shadowing Relaxation (LSR) is presented as an alternative …

The Role Of Sexual Network Core Groups In Disease Epidemics, Jason Janeaux

LSU Doctoral Dissertations

Sexually transmitted infections (STIs) remain an economic and social burden, non-discriminately affecting sexually active individuals worldwide. The unique transmission of STIs is dependent upon host and pathogen life histories, as well as the underlying network structure of the host population. Within a population there is a group of individuals, the core group, that maintains STI presence and helps sustain ongoing transmission both within the core group and in the surrounding population. While the presence of these core groups is well documented, the criteria for inclusion into a sexual core group is not. In this dissertation, I explore common factors that …

Digital Agriculture Applications In Maize Nutrient Management And Soybean Crop Stands Assessment, Bhawana Acharya

LSU Master's Theses

High soil moisture from frequent excessive precipitation can reduce maize (Zea mays L.) yield and increase nitrogen (N) loss. Early-stage soybeans (Glycine max) are also susceptible to damage under these conditions. Traditional methods for assessing N status in maize and plant stands in soybean are labor-intensive and time-consuming. In this study, UAV remote sensing was used to assess maize N status under different N rates and excessive soil moisture. For soybeans, we compared a blob detection method with the YOLOv8 model to estimate plant density using ground images from a handheld camera. Additionally, YOLOv8 performance was evaluated …
