Investigations On The Use Of Hyperthermia For Breast Cancer Treatment, Sreekala Suseela

Electronic Theses and Dissertations, 2020-2023

Hyperthermia using electromagnetic energy has been proven to be an effective method in the treatment of cancer. Hyperthermia is a therapeutic procedure in which the temperature in the tumor tissue is raised above 42°C without causing any damage to the surrounding healthy tissue. This method has been shown to increase the effectiveness of radiotherapy and chemotherapy. Radio frequencies, microwave frequencies or focused ultrasound can be used to deliver energy to the tumor tissue to attain higher temperatures in the tumor region for hyperthermia application. In this dissertation the use of a near field focused (NFF) microstrip antenna array for the …

The Innate Immune Response To House Dust Mite In Allergic Airway Inflammation, Madelyn Miller Jan 2020

The Innate Immune Response To House Dust Mite In Allergic Airway Inflammation, Madelyn Miller

Electronic Theses and Dissertations, 2020-2023

House dust mite (HDM) is an indoor aeroallergen which is commonly associated with the development of allergic rhinitis and allergic asthma. In fact, up to 70% of allergic asthmatic individuals have been shown to demonstrate reactivity towards HDM allergens. The downstream adaptive immune response to HDM is well characterize and is described as being largely T helper cell type 2 (Th2) and partly T helper cell type 17 (Th17) dominated. However, less is known about how resident antigen presenting cells (APCs) and structural cells such as airway epithelial cells recognize and respond to HDM. Unlike other microbial antigens, recognition of …

The Good Ol' Days: How Sociopolitical Climate Influences Motivations To Seek Historical Nostalgic Media Experiences Versus Non-Nostalgic Media Experiences And The Outcomes Of Those Experiences, Samantha Rosenthal Jan 2020

The Good Ol' Days: How Sociopolitical Climate Influences Motivations To Seek Historical Nostalgic Media Experiences Versus Non-Nostalgic Media Experiences And The Outcomes Of Those Experiences, Samantha Rosenthal

Electronic Theses and Dissertations, 2020-2023

Nostalgia is a complex cognitive and affective experience and has been described by some as a "social emotion" (Goulding, 2002; Merchant & Rose, 2013; Wildschut et al., 2006). Through nostalgic media experiences, people can develop connections to prior eras or periods in society which are accompanied by a range of emotions and feelings. Perceptions of the past are influenced by experiences in the present. Because of this, it is possible that people's perceptions of their current political climates and society play a role in how they seek and react to media experiences, including nostalgic media experiences. Considering how the political …

Identification Of Novel Antimalarials From Natural Product Inspired Libraries, David Perry

Electronic Theses and Dissertations, 2020-2023

To identify novel antimalarials from unexplored areas of chemical space, we have utilized two approaches: (a) using Torrey Pines Institute for Molecular Studies (TPIMS) proprietary high-density combinatorial libraries containing a large number of small molecule compounds residing largely in the underexplored areas of chemical space; and, (b) using novel, complexity-to-diversity/ring distortion of available natural products. The first approach involved the screening of more than 30 million compounds derived from 81 small molecule libraries, built on 81 distinct scaffolds. From this, we identified the pyrrolidine bis-cyclic guanidine library (TPI-1955) to be one of the most active and selective for antiplasmodial activity. …

A Legacy Of Community And Mourning: Aids & Hiv In Central Florida, 1983-1993, Andrew Weeks Jan 2020

A Legacy Of Community And Mourning: Aids & Hiv In Central Florida, 1983-1993, Andrew Weeks

Electronic Theses and Dissertations, 2020-2023

Given the primacy of Florida, and in particular Orlando, as an urban center with an above average rate of AIDS and HIV, this study examines how the outbreak of a deadly disease can affect a community. Complicating the response to this scourge, those who were most at-risk were marginalized groups such as those in the LGBTQ community, drug users, and often people of color. As a result, those who occupied positions of political power felt little incentive to curb the epidemic and mocked it by deeming it "the gay disease." As a result of neglect and the lack of investment …

Using The Enneagram As A Lens For Culturally Sustaining Pedagogy In The Ninth Grade English Language Arts Classroom, Catherine Caudle

Electronic Theses and Dissertations, 2020-2023

This study explores the relationship between student personality, student choice in novel selection in the high school language arts classroom, and student reading self-efficacy and enjoyment. Throughout a student's educational journey, from elementary school to high school, it is typical to see a decrease in student choice regarding the literature they read. In elementary grades, students learn about the parts of a book, are frequently read to with animated voices, and look forward to shelves of choice on library trips. Yet as students move into their middle and high school years, the excitement often dwindles. Choice is removed, for a …

Tunable Few- To Many-Cycle Source For High-Order Harmonic Generation And Time-Resolved Spectroscopy, John Beetar Jan 2020

Tunable Few- To Many-Cycle Source For High-Order Harmonic Generation And Time-Resolved Spectroscopy, John Beetar

Electronic Theses and Dissertations, 2020-2023

The temporal confinement of laser light pulses to durations approaching the optical period, and the subsequent conversion of these pulses into extreme ultraviolet and x-ray wavelengths through the process of high-order harmonic generation (HHG), has enabled measurement and control of ultrafast processes spanning picosecond to attosecond timescales. Typically achieved by nonlinear compression of multi-cycle pulses in gas-filled hollow-core fibers, compression to single-and even sub-cycle durations is now becoming routine due to the availability of state-of-the-art Ti:sapphire laser amplifiers outputting millijoule level pulses with pulse durations below ten cycles. Even so, reliance on mJ-level Ti:sapphire lasers has in most cases limited …

The Improvement Of Shewhart-Stable Time Series Processes By Applying Jensen-Shannon Complexity Measures To Characterize Emergent Structure, Blaine Lorimer Jan 2020

The Improvement Of Shewhart-Stable Time Series Processes By Applying Jensen-Shannon Complexity Measures To Characterize Emergent Structure, Blaine Lorimer

Electronic Theses and Dissertations, 2020-2023

Despite the nearly universal imperative to continuously improve processes, Shewhart-stable time series are often ignored for improvement because of various generalized assumptions and "rules", many of which are actually very context dependent. The process control literature presents widely divergent views, including the extreme position that stable processes are completely random and therefore any further compensation ("tampering") can only increase process variability. The traditional reductionist approach to process improvement characterizes underlying factors using statistical variance measures, which has been very effective for unstable processes. However, this approach, especially when it involves Shewhart control charts, is generally much less effective for directing …

Parallelized X-Ray Tracing With Gpu Ray-Tracing Engine, Joseph Ulseth Jan 2020

Parallelized X-Ray Tracing With Gpu Ray-Tracing Engine, Joseph Ulseth

Electronic Theses and Dissertations, 2020-2023

X-ray diffraction tomography (XDT) is used to probe material composition of objects, providing improved contrast between materials compared to conventional transmission based computed tomography (CT). In this work, a small angle approximation to Bragg's Equation of diffraction is coupled with parallelized computing using Graphics Processing Units (GPUs) to accelerate XDT simulations. The approximation gives rise to a simple yet useful proportionality between momentum transfer, radial distance of diffracted signal with respect to incoming beam's location, and depth of material, so that ray tracing may be parallelized. NVIDIA's OptiX ray-tracing engine, a parallelized pipeline for GPUs, is employed to perform XDT …

Fluorescence Microscopy With Tailored Illumination Light, Jialei Tang

Electronic Theses and Dissertations, 2020-2023

Fluorescence microscopy has long been a valuable tool for biological and medical imaging. Control of optical parameters such as the amplitude, phase, polarization and propagation angle of light gives fluorescence imaging great capabilities ranging from single molecule imaging to long-term observation of living organisms. While numerous fluorescence imaging techniques have been developed over the past decades, there is always an inevitable tradeoff among the spatial resolution, imaging speed, contrast, photodamage and the total cost when it comes to choose the appropriate microscope. A main goal of my dissertation research is to develop state-of-the-art microscope systems that exhibit unprecedented performance in …

Iterative Optical Diffraction Tomography For Reconstruction Of Multiply-Scattering Objects, Shengli Fan Jan 2020

Iterative Optical Diffraction Tomography For Reconstruction Of Multiply-Scattering Objects, Shengli Fan

Electronic Theses and Dissertations, 2020-2023

As a label-free, non-destructive, high-resolution, and quantitative imaging technique, optical diffraction tomography (ODT) has been widely used to image biological samples and microstructures, such as cells, tissues, and optical fibers. The refractive-index (RI) distribution of an object is reconstructed from multi-view measurements of diffracted fields emerging from the object. Typical ODT setups include the object rotating configuration (ORC) and the illumination scanning configuration (ISC). One major limitation of ODT is that it is only applicable to weakly-scattering objects. In this dissertation, novel methods have been developed to overcome the reconstruction difficulty caused by multiple scattering, so as to extend ODT …
