Host-Microbiome Interactions In The Teleost Brain, Amir Mani Varnoosfaderani

Biology ETDs

This dissertation investigates host-microbial interactions within the teleost brain, previously considered sterile. Reviewing current literature highlights significant gaps in understanding teleost brain immunity, despite prevalent neurotropic diseases. We mapped the immune profiles of rainbow trout brains and meninges, revealing the olfactory bulbs as the immune effector part of the brain and the optic tectum as a nod2 expression hub. High il6 and il10 levels were noted in the telencephalon. A persistent bacterial community within healthy salmonid brains shares diversity with gut and blood microbiota. Brain bacterial isolates exhibit genomic signatures for brain colonization and polyamine biosynthesis. The microbiota shifts across …

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 …

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 …

Earth and Planetary Sciences ETDs

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 …

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 …

This dissertation demonstrates the feasibility of semiconductor-based LGS systems using the membrane external-cavity surface-emitting laser (MECSEL) platform, employing multiple quantum wells. Various laser cavity configurations were analyzed through simulations and experiments. The in-well pumping method was explored to reduce the quantum defect and address thermal limitations. Multi-pass pumping schemes were designed with Zemax modeling and demonstrated experimentally. To simplify multi-pass pumping, the hybrid-MECSEL (H-MECSEL) design was introduced. COMSOL modeling studied thermal management and thermal lensing effect.

The H-MECSEL achieved approximately 30 W of output power at …

The Borders Of Embodiment: Transgression, Transformation, And Corporeality In Chicanx Speculative Fiction, Chrysta Carson Wilson

English Language and Literature ETDs

This dissertation develops a clearer vision of Chicanx Speculative Fiction (SF) as its own genre anchored to the experiences and histories of the Chicanx community, with a particular interest in the avenues through which race and gender shape the experience of embodiment. SF resists hegemonic narratives that justify racial hierarchies and reveals both the cultural and concrete pressures exerted on Chicanx bodies in the United States as a minoritized and often exploited community. Furthermore, my analysis illustrates that Chicanx writers utilize elements of SF to defamiliarize traditional notions of race, class, and nationality. Through the use of defamiliarization, Chicanx SF …

Carbonate And Organic Proxies And The Impacts Of Climate On Lake Systems: Paleoclimate Interpretations From Lake Chalco, Mexico, Aria Holmes

Earth and Planetary Sciences ETDs

This project incorporates several lines of evidence to better understand the climate at Lake Chalco. Chapter 1 utilizes oxygen isotopes from carbonates and show that the Inter Tropical Convergence Zone varies on primarily glacial and millennial timescales; precession is not observed. These data indicate glacials periods were shallower and interglacials were wetter periods at Lake Chalco. Chapter 2 studies carbon, nitrogen, C/N, and TOC proxies and finds that the lake conditions during the glacials and interglacials are primarily a mixed algal-macrophyte-terrestrial organic matter. Deviations show that the lake during the interglacials had more algal organic matter- reflecting influxes of nutrients …

Through in-depth interviews with six out of eight team members, I explored IEP team members’ perceptions of their and others’ responsibilities and contributions to the development of an annual IEP. Qualitative coding revealed four key decision-making themes: Unspoken norms, privileging professional knowledge, avoiding conflict and responding to disagreements, and identifying your place at the …

On The Surface Topography Of Local Overheating And Plasma Formation Due To Initial Condition Perturbations Sourcing The Electrothermal Instability On High-Current-Density Conductors, Maren Whiting Hatch

Electrical and Computer Engineering ETDs

The electrothermal instability (ETI) is a Joule heating-driven instability that instigates runaway heating on conductors driven to high current density, altering the 3D evolution of the expansion and phase state. Most metals include complex distributions of imperfections (voids, resistive inclusions) which seed ETI. To simplify comparison with modeling and theory, experiments examined growth of ETI from various alloys of stainless steel as well as relatively void/inclusion free, 99.999% pure, diamond-turned, 1 mm-diameter aluminum rods. Aluminum surfaces included a variety of deliberately machined and well-characterized perturbations, including 10-micron-scale quasi-hemispherical voids, or “engineered” defects (ED), and sinusoidal patterns of varying wavelength and …

Pulsed Secondary Electron Yield Measurements Of Metallic And Dielectric Materials Of Interest For High Power Vacuum Electron Devices, Bilal Ahmed Malik

Electrical and Computer Engineering ETDs

Secondary electron emission (SEE) from conductors is thought to play an important role in the initiation of Multipactor breakdown in vacuum electron devices. The SEE of dielectric materials plays a crucial role in numerous scientific and technological applications, including particle accelerators, spacecraft charging, and plasma diagnostics. Additionally, the SEE of an insulator may depend on its electrical stress history. In both cases, SEE strongly depends on any conditioning of the material surface. We present measurements on both conducting and insulating materials of interest in these applications. Measurements are being made in an existing test stand, recently modified to enable measurements …
