Identifying Potential Antibiotic Uptake Mechanisms Of Streptococcus Pneumoniae, Yuri Laguna Terai
Identifying Potential Antibiotic Uptake Mechanisms Of Streptococcus Pneumoniae, Yuri Laguna Terai
Theses and Dissertations
Streptococcus pneumoniae (pneumococcus) is a commensal gram-positive colonizer of the human nasopharynx capable of causing diseases including otitis media, pneumonia, bacteremia, and meningitis. Although it is often a harmless colonizer, there is a high rate of mortality and morbidity among the immunocompromised, elderly, and young children. While these infections can often be treated with antibiotics, resistance to numerous antibiotics is increasing. Antibiotic resistance is a well-studied dilemma; however, little information is known of how bacteria take up certain antibiotics. Because most antibiotics cannot diffuse freely across the bacterial cell wall, we hypothesize that metabolite transport proteins participate in the uptake …

Common Mode Electromagnetic Interference Attenuation For Dc/Ac Inverters Using Enhanced Sinusoidal Frequency Modulation Technique, Dinh Le
Theses and Dissertations
Common mode (CM) electromagnetic interference (EMI) can compromise electronics systems, interfere with communication systems, and degrade mechanical systems. Multiple inverters can also generate excessive CM EMI that often exceeds individual inverter EMI standards. Due to their weight, volume, cost, and suboptimal performance, active and passive filters and chokes are inefficient as EMI mitigation options. By utilizing frequency modulation (FM) or spread spectrum frequency modulation (SSFM), EMI energy is dispersed. In spite of not requiring expensive, bulky, and heavy filters, these techniques produce significant ripples in output voltages and currents. This dissertation uses enhanced sinusoidal frequency modulation to reduce CM EMI …

Uncertainty-Aware Path Planning On Aerial Imagery And Unknown Environments, Charles Alan Moore
Uncertainty-Aware Path Planning On Aerial Imagery And Unknown Environments, Charles Alan Moore
Theses and Dissertations
Off-road autonomous navigation faces a significant challenge due to the lack of maps or road markings for planning paths. Classical path planning methods assume a perfectly known envi- ronment, neglecting the inherent perception and sensing uncertainty from detecting terrain and obstacles in off-road environments. This research proposes an uncertainty-aware path planning method, URA*, using aerial images for autonomous navigation in off-road environments. An ensemble convolutional neural network model is used to perform pixel-level traversability estima- tion from aerial images of the region of interest. Traversability predictions are represented as a grid of traversal probability values. An uncertainty-aware planner is applied …

Collectors Versus Non-Collectors With Hoarding Symptoms, Caitlyn A. Nix
Collectors Versus Non-Collectors With Hoarding Symptoms, Caitlyn A. Nix
Theses and Dissertations
Research assessing the diagnostic criteria for hoarding disorder has firmly differentiated hoarding disorder from normative collecting. However, there has been no examination of non-normative collecting – that is, collectors that experience elevated hoarding symptoms. The current study utilized an online survey to explore differences between self-identified collectors (n = 140) and non-collectors (n = 169) in externalized hoarding symptoms, saving cognitions, and psychosocial functioning. Collectors reported higher general self-efficacy and higher need for control of items than non-collectors. Hoarding symptoms were not significantly different between collectors and non-collectors. These results suggest that identifying as a collector does not significantly change …
