Emission Spectroscopy Of Ingaas Quantum Dots Via High-Resolution Fabry-Perot Interferometer, Raju Bhai Kc

Graduate Theses, Dissertations, and Problem Reports (ETD)

Single photons emitted from self-assembled quantum dots have been widely studied to use as a promising qubit for quantum information processing. Therefore, it is critical to fully understand the emission spectra from the quantum dot's excitation if we want to use a single photon as a quantum bit. It is almost impossible to produce rotationally symmetric quantum dots due to various growth conditions and restrictions. So the real quantum dots do not have a perfectly symmetric structure. A broken rotational symmetry causes an asymmetric exchange interaction between electron and hole, leading to a fine structure splitting between two excited states. …

How Do College Student-Athletes’ Understanding And Expectations Of Mindfulness And Self-Compassion Change Through An Intervention?, Blake Costalupes

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the last two decades, mindfulness has permeated sport, exercise, and performance psychology (SEPP). Mindfulness research in SEPP primarily focuses on the efficacy of manualized protocols on various outcomes related to performance and wellbeing; how athletes understand this complex construct, though, is largely unexplored in the literature. Additionally, some researchers suggest that the potentially paradoxical adoption of mindfulness in Western psychology may be contributing to limited outcomes, low engagement in, and poor adherence to mindfulness-based interventions (MBIs). In addition, the exploration of self-compassion as a mechanism for change through mindfulness practice has increased in recent years, making it an important …

Generative Adversarial Network And Its Application In Aerial Vehicle Detection And Biometric Identification System, Moktari Mostofa

Graduate Theses, Dissertations, and Problem Reports (ETD)

In recent years, generative adversarial networks (GANs) have shown great potential in advancing the state-of-the-art in many areas of computer vision, most notably in image synthesis and manipulation tasks. GAN is a generative model which simultaneously trains a generator and a discriminator in an adversarial manner to produce real-looking synthetic data by capturing the underlying data distribution. Due to its powerful ability to generate high-quality and visually pleasing
results, we apply it to super-resolution and image-to-image translation techniques to address vehicle detection in low-resolution aerial images and cross-spectral cross-resolution iris recognition. First, we develop a Multi-scale GAN (MsGAN) with multiple …

Three Essays On Emotional Cues, Clay Collins

Graduate Theses, Dissertations, and Problem Reports (ETD)

The first paper investigates the relationship between intimate partner violence (IPV) and United States presidential elections. There exists a sizeable literature studying IPV that occurs during or after stressful events (such as a sports team loss), and a considerable non-economics literature examining election-related stress. However, very limited research has been done studying potential negative outcomes after a political loss (when one’s candidate loses), and these findings in other fields have not been synthesized into the economics lexicon. By interacting with the margin of victory for each state, I find large and significant decreases in IPV in states that vote for …

Specialized Metabolism In Retina, Retinal Pigmented Epithelium, And Testis, Siyan Zhu

Graduate Theses, Dissertations, and Problem Reports (ETD)

The retina and its neighboring retinal pigmented epithelium (RPE) are high energy-demanding and metabolically active tissues with specialized and complementary metabolism. They are metabolically interdependent and impact each other’s viability. Interestingly, many of the metabolic features in the retina and RPE are shared with the testis. For example, testis is also energy costly due to continuous sperm differentiation and it has similar metabolic inter-dependence between different testis cells. Both the retina and testis are vulnerable to mitochondrial metabolic impairments.

We conducted three research projects to understand 1) the nutrient utilization and communication in retina and RPE; 2) The profiling of …

Effects Of Invasive Species On Ohio River Zooplankton, Samuel John Johnston

Graduate Theses, Dissertations, and Problem Reports (ETD)

Invasive species have the potential to dramatically change both aquatic and terrestrial ecosystems with rates of introduction only expected to increase across the Globe. In the Mississippi River basin filter feeding silver (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis) collectively known as invasive carp were introduced into aquaculture ponds where they subsequently escaped and spread to interconnected basins. Invasive carp have not yet completely established throughout the entire Ohio River. Managers recognize three distinct phases of carp invasion: establishment front, invasion front and presence front. In the Illinois River invasive carp are very well established and …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis (TB), a predominantly respiratory pathogen responsible for over ten million infections and one million deaths last year. Despite it being a primary objective of the World Health Organization (WHO) for several decades to irradicate TB, progress toward this objective has fallen short of the 2020 target to end TB by 2035. Meeting this goal will require advancements in diagnostic tools, education, healthcare access, and treatments and preventatives. Regarding prevention, the primary tool for this strategy is through vaccination. Currently, the only licensed vaccine for protection against TB is the century old …

An Assessment Of The Forensic Aspects Of Genetic Genealogy, Sarah Hester

Graduate Theses, Dissertations, and Problem Reports (ETD)

Forensic genetic genealogy has grown in both popularity and controversy in recent years. The genetic information comes from large numbers of single nucleotide polymorphism (SNP) markers. Polymorphism variations can be traced through familial lineage, determining how closely individuals are related to each other based on the similarities and differences in SNPs within their DNA. Polymorphisms account for approximately 85% of human variation. Genealogy and ancestry determination companies trace the lineage of a person back through multiple generations using polymorphisms. As more individuals submit their DNA for analysis the genealogical profile databases continue to grow in size. Law enforcement uses genealogical …

The Investigation Of Novel Bovine Oocyte-Specific Long Non-Coding Rnas And Their Roles In Oocyte Maturation And Early Embryonic Development, Jaelyn Zoe Current

Graduate Theses, Dissertations, and Problem Reports (ETD)

Early embryonic loss is a significant factor in livestock species' infertility, resulting in an economic deficit. In cattle, the in vivo fertilization rate is ~90%, with an average calving rate of about 55%, indicating an embryonic-fetal mortality rate of roughly 35%. Further, 70-80% of total embryonic loss in cattle occurs during the first three weeks after insemination, particularly between days 7-16. Growing evidence indicates that the oocyte plays an active role in regulating critical aspects of the reproductive process required for successful fertilization, embryo development, and pregnancy. However, defining oocyte quality remains enigmatic. Recently, many have abandoned the notion that …

Rare earth elements (REEs) are critical in emerging clean energy, advanced technologies, and military defense applications due to their unique physical, chemical, optical, and luminescent properties. Given the potential supply chain restrictions imposed by one country's dominance in the global REE market and the consistently growing demand for REEs, developing the US domestic REE supply chain is imperative. Thus, alternative sources are crucial to supply the demand and prevent interruption in manufacturing products that consume REEs. Concurrently, acid mine drainage (AMD) is a long-standing and widespread global challenge the mining industry encounters. AMD is generated in large volumes and continuously …

Expansion On The Use Of The Novel Compound, Elp-004, Using A Mycobacterium Tuberculosis Experimentation Model, Kendyl Marie Berry

Graduate Theses, Dissertations, and Problem Reports (ETD)

Osteoarticular tuberculosis (OAT) is a bone degenerative disease that results in bone erosion, joint effusion, joint swelling, and sometimes, nerve compression. OAT occurs from the hematogenous dissemination of Mycobacterium tuberculosis (Mtb) bacilli spreading from the primary site of infection to the bones and joints; the primary site of infection tends to be the lungs as pulmonary tuberculosis infections are the most common. OAT can occur as the result of an active or latent infection. Latent infections result in OAT when bacilli are able to escape granulomas. The incidence of OAT is not as high as pulmonary infections, making up about …

A Study Of Accidental Daughter Crystals In Fluid Inclusions In Bedded Halite From The Permian Opeche Shale And Cedar Hills Sandstone Of The Midcontinental United States, Ryan James Prchlik

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ancient acid-saline lakes of the midcontinental United States deposited bedded halite during Permian time. These deposits are not typically preserved at the surface, but drill cores of the Opeche Shale of North Dakota and Cedar Hills Sandstone of Kansas contain preserved beds of halite. Halite from these ancient lakes have primary fluid inclusions that contain Permian lake water. Also included are accidental daughter crystals that were trapped inside the fluid inclusions at time of halite precipitation. Both the fluid and daughter crystals inside bedded halite can tell us about the geochemistry of original lake waters of Pangea.

Multimodal Neuron Classification Based On Morphology And Electrophysiology, Aqib Ahmad

Graduate Theses, Dissertations, and Problem Reports (ETD)

Categorizing neurons into different types to understand neural circuits and ultimately brain function is a major challenge in neuroscience. While electrical properties are critical in defining a neuron, its morphology is equally important. Advancements in single-cell analysis methods have allowed neuroscientists to simultaneously capture multiple data modalities from a neuron. We propose a method to classify neurons using both morphological structure and electrophysiology. Current approaches are based on a limited analysis of morphological features. We propose to use a new graph neural network to learn representations that more comprehensively account for the complexity of the shape of neuronal structures. In …

Graduate Theses, Dissertations, and Problem Reports (ETD)

With the introduction of a larger portion of renewable sources of power coming onto the U.S. power grid in recent decades, the operational strategy of coal-fired power plants has changed significantly to focus more on flexibility in response to the changing energy market. This has naturally led to different operational challenges. Many of these challenges are focused on the boilers within these plants, as they are producing more emissions and experiencing increased damage during load-following, which in turn leads to increased costs from penalties for not achieving emission standards or maintenance costs as boilers accumulate damage from the cycling behavior. …

Optimal Path Planning For Aerial Robots Using Genetic Algorithm, Anna Puigvert I Juan

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis presents a path optimization solution for a robot in two different constrained 3-dimensional (3D) environments. The robot is required to travel from its current position to a goal position following minimum cost paths (optimal paths). The first environment has 3D obstacles that interfere with the robot’s path. The path cost for this environment accounts for the minimum distance traveled by the robot from the start to the goal position while avoiding obstacles. The second environment is the atmosphere of Venus, specifically a flyable region of this atmosphere with characteristics similar to Earth’s. This environment has strong westward winds …
