Spatio-Temporal Dynamics Of Fungal Communities And Their Effects On Plants, Kel Cook

Biology ETDs

Fungi perform several critical functions in the environment. Spatiotemporal distributions of fungal communities will mediate when and where these functions happen and how they vary across the landscape. I first explored tropical tree canopy fungal community variation at small spatial scales and documented near total turnover of fungi across sub-meter distances and among adjacent substrates. The second chapter analyzed fungal turnover over the course of three years, where community stability was driven primarily by abundant fungi. In the third chapter, I tested effects of the environment, including host plant and habitat, on canopy fungal communities and found only small effects, …

From Wave Propagation To Spin Dynamics: Mathematical And Computational Aspects, Oleksii Beznosov

Mathematics & Statistics ETDs

In this work we concentrate on two separate topics which pose certain numerical challenges. The first topic is the spin dynamics of electrons in high-energy circular accelerators. We introduce a stochastic differential equation framework to study spin depolarization and spin equilibrium. This framework allows the mathematical study of known equations and new equations modelling the spin distribution of an electron bunch. A spin distribution is governed by a so-called Bloch equation, which is a linear Fokker-Planck type PDE, in general posed in six dimensions. We propose three approaches to approximate solutions, using analytical and modern numerical techniques. We also present …

Mind maps were posted online for the intervention class following each chapter lecture. Students tracked their study methods, including whether they used the mind maps. Exam scores and final grades were analyzed and compared for differences in learning and course performance between groups. There were no statistically significant differences in exam scores or …

Mucosal Immune System Of African Lungfish, Ryan D. Heimroth

Biology ETDs

Conquering land was an apex moment in the evolution of vertebrates. Physiologically, the first vertebrates to transition to life on land had to adapt in order to survive in an oxygen-rich environment where gravitational forces and limited water prevailed. Several extant vertebrates including anurans and lungfish, survive droughts by undergoing aestivation. Unfavorable environmental conditions trigger lungfish to aestivate. Aestivation is a process of metabolic torpor wherein the fish will encase itself in a mucus cocoon and not move until favorable environmental conditions (food and water) are reintroduced. Aestivation can be reproduced in laboratory settings and, thus, lungfish can be used …

Is It Time To Revisit Qualified Immunity?, Joseph A. Schremmer, Sean M. Mcgivern

Faculty Scholarship

The right to sue and defend in the courts of the several states are essential privileges of citizenship. Eight generations ago, this right was unavailable to black people, because descendants of African slaves were never intended to be citizens. Then, and for years to come, local governments failed to protect African Americans from violence and discrimination and were sometimes complicit in those violations.

Qualified immunity was born in 1982 when the Supreme Court decided Harlow v. Fitzgerald. With an outflow of questionable court decisions shielding officers solely because they act under color of state law, it is time for the …

Predictors Of Birth Center Sustainability In The United States, Melanie Cabezas Phipps

Nursing ETDs

Pregnant women from all racial and socioeconomic communities deserve safe, personalized, and affordable ways to give birth. To meet all three needs, focus is increasing on birth centers, a midwifery model that provides family-centered care before, during, and after normal pregnancy, labor, and birth. However, many U.S. birth centers face significant obstacles to financial sustainability, particularly in rural areas. A better understanding of the factors that contribute to a birth center’s operational success is needed for practitioners and groups interested in establishing or maintaining a birth center, as well as to inform policymakers seeking to improve health care equity, outcomes, …

Predictors Of Recovery In Advocacy-Based Refugee Treatment Outcome: The Role Of Prior Traumatic Experiences And Current Chronic Stressors, Meredith A. Blackwell

Psychology ETDs

Refugees are at an increased vulnerability to mental health disorders compared to citizens of wealthier nations. The present study looks at the symptom trajectories of 290 refugees in a psychosocial community-based participatory intervention. A three-level generalized linear mixed model examined the predictive impact of exposure to trauma and chronic stress at baseline on posttraumatic stress and mood symptoms over time. Results showed that only higher chronic stress at baseline was associated with a steeper decrease in both PTSD and mood scores, but these effects differed by nationality. However, with chronic stress entered as a time-varying covariate instead only African participants …

Effects Of Closed Loop Transcranial Alternating Current Stimulation Targeting Slow Oscillation Sleep On Post-Sleep Object Location Learning, Bradley M. Robert

Psychology ETDs

Modulating sleep architecture to augment memory performance can provide valuable insight into how sleep contributes to memory. Slow wave activity has been identified as an important contributor to sleeps impact on memory. While the beneficial role of SWS in offline consolidation is well established research investigating SWS’s role in post-sleep memory formation is limited. Here we investigated the relationship between SWS and post-sleep learning by modulating slow wave oscillations (SWO) with closed loop transcranial alternating current stimulation (tACS) with an aim toward enhancing learning capacity for object location associations. Thirty-six subjects were randomly assigned to either sham (21) or verum …

Comparing Deep Learning And Immunohistochemistry In Determining The Site Of Origin For Well-Differentiated Neuroendocrine Tumors, Jordan Redemann, Fred A. Schultz, Cathy Martinez, Michael Harrell, Douglas P. Clark, David R. Martin, Joshua A. Hanson

Pathology Research and Scholarship

Background: Determining the site of origin for metastatic well-differentiated neuroendocrine tumors (WDNETs) is challenging, and immunohistochemical (IHC) profiles do not always lead to a definitive diagnosis. We sought to determine if a deep-learning convolutional neural network (CNN) could improve upon established IHC profiles in predicting the site of origin in a cohort of WDNETs from the common primary sites.

Materials and methods: Hematoxylin and eosin (H&E)-stained tissue microarrays (TMAs) were created using 215 WDNETs arising from the known primary sites. A CNN trained and tested on 60% (n = 130) and 40% (n = 85) of these cases, …

A Two-Dimensional Spherical-Polar Multigroup Discrete Ordinates Code For Atmospheric Particle Transport, Daniel T. Wakeford

Nuclear Engineering ETDs

A natural coordinate system for calculating neutral particle propagation in the atmosphere due to point sources is two-dimensional spherical-polar coordinates. Deterministic methods for solving the transport equation in this coordinate system require some interesting implementation details stemming from the two angular derivatives present in this form of the equation. In this dissertation, we present a bilinear discontinuous spatial discretization of the transport equation in this coordinate system. The weighted diamond difference discretization is applied to the angular derivative term in two angular dimensions, using zero-weighted starting directions to start the differencing. To our knowledge, the only previous deterministic code that …

A First Principles Study Of Secondary Electron Yield Of Metals And Alloys: Cu, Ni, Zn, Cuni, And Cuzn, Raul Enrique Gutierrez

Electrical and Computer Engineering ETDs

This thesis discusses the material properties of metals and alloys through a Density Functional Theory (DFT) perspective. It also establishes computational procedures necessary to predict the Secondary Electron Yield (SEY) from first principles. First, DFT calculations were carried out to calculate material properties important in the secondary electron generation and emission process, such as work function, Fermi energy, density of states, and more importantly, frequency- and momentum-dependent energy loss functions. These material properties are then used in Monte Carlo simulations to produce the energy-dependent SEY for CuNi and CuZn alloys, as well for the component metals Cu, Ni, and Zn. …

Comparison Of Virulence Gene Carriage In Staphylococcus Aureus Isolates Colonizing Human Skin And Those Associated With Soft Tissue Osteoarticular Infections, Kylie Disch, Jon Femling, Parisa Mortaji, Kurt Schwalm, Aimee Yousey, Rebekkah Varjabedian, Darrell Dinwiddie, Walter Dehority

2020 Pediatric Research Forum Session

Background:

Osteoarticular infections (OAI), most commonly caused by S. aureus, cause extreme morbidity in children and may result in permanent sequelae (e.g. limb-length discrepancies). However, S. aureus is also a common colonizing bacteria of skin and a cause of soft tissue abscesses. Virulence determinants for S. aureus are likely complex, and may include the genetic composition of the isolate, the host immune response and the transcriptomic profile of the organism. A necessary first-step in characterizing these virulence factors includes assessing virulence gene carriage between S. aureus isolates from children with OAIs and from less virulent isolates.

Methods:

Introducing The Self-Cleaning Filtration For Water Quality Sensors (Sc-Flawless) System, Aashish Sanjay Khandelwal

Civil Engineering ETDs

Sensor-based, semi-continuous observations of water quality parameters have become critical to understanding how changes in land use, management, and rainfall-runoff processes impact water quality at diurnal to multi-decadal scales. While some commercially available water quality sensors function adequately under a range of turbidity conditions, other instruments, including those used to measure nutrient concentrations, cease to function in high turbidity waters (> 100 NTU) commonly found in large rivers, arid-land rivers, and coastal areas. This is particularly true during storm events, when increases in turbidity are often concurrent with increases in nutrient transport. Here, we present the development and validation of …

γ9δ2T cells play a major role in cancer immune surveillance, yet the clinical translation of their in vitro promise remains challenging. To address limitations of previous clinical attempts using expanded γ9δ2T cells, we explored the clonal diversity of γ9δ2T cell repertoires and characterized their target. We demonstrated that only a fraction of expanded γ9δ2T cells was active against cancer cells and that activity of the parental clone, or functional avidity of selected γ9δ2 T cell receptors (γ9δ2TCRs), was not associated with clonal frequency. Furthermore, we analyzed the target-receptor interface and provided a 2-receptor, 3-ligand model. We found that activation was …
