Investigating Smooth Muscle Myosin Dynamics And Assembly In Physiology And Pathology, Maggie Bennett

Dissertations

Vascular smooth muscle cells (SMCs) surround many blood vessels throughout the body,where they dynamically alter vessel diameter to regulate blood pressure, provide structural integrity, and absorb shock on a beat-to-beat timescale. As smooth muscle function fails, profound vascular disease ensues, often with tragic results- even death. Smooth muscle myosin 2 (SM2) is the dominant motor protein that actuates contractility and allows SMCs to perform these vital functions. To function, SM2 monomers dynamically assemble into filaments, which upon SMC activation, associate with filamentous actin to drive contractility. Despite the critical contribution of SM2 to SMC function, foundational aspects of SM2 assembly …

Semantic Deduplication Of Redundant And Non-Conformant Data In Temporal Domains, Jon C. Rogers

Dissertations

Semantic deduplication is the process of identifying records that describe or are derivative of the same entity and is a crucial task when merging data pulled at different times and/or from multiple sources. Failure to resolve these duplicates may bias the data and the applications and models that use them. Duplicates may range in nature from exact matches to more interesting cases where the data differs due to syntactic representation, missing or updated information, or adversarial transforms. The implications of duplication may go beyond redundancy to include recognizing critical information updates, error detection, and identifying similar behaviors. This task is …

Fermi-Gbm : The 10 Year Spectral Catalog And Exploring Physically-Motivated Models To Fit Gamma-Ray Burst Spectra, Suraj Poolakkil

Dissertations

Gamma-ray Bursts (GRBs) are ultra-relativistic jets of plasma and radiation formed by two known progenitors: core-collapse supernovae (a.k.a. “collapsars”) and binary mergers of compact objects, especially neutron stars. They have been studied extensively since their discovery in the 1960s, but many aspects of their prompt emission remain a mystery. In the first part of this dissertation I present the systematic spectral analyses of GRBs detected by the Fermi Gamma-ray Burst Monitor during its first ten years of operation. It consists of spectral fits from 2297 GRBs, resulting in a compendium of over 18,000 spectra. In the second part, I explore …

Mammalian Dihydropyrimidine Dehydrogenase: Employing Transient State Kinetic Methods To Determine Catalytic And Inhibitory Mechanisms, Dariush Forouzesh

Dissertations

Dihydropyrimidine dehydrogenase (DPD) catalyzes the two-electron reduction of pyrimidine bases uracil and thymine as the first step in pyrimidine catabolism. The enzyme achieves this simple chemistry using a complex cofactor set including two flavins and four Fe4S4 centers. The flavins, FAD and FMN, interact with respective NADPH and pyrimidine substrates and the iron-sulfur centers form an electron transfer wire that links the two active sites that are separated by 56 Å. DPD accepts the common antineoplastic agent 5-fluorouracil (5FU) as a substrate and so undermines the establishment of efficacious toxicity. Though studied for multiple decades, a precise description of the …

A Computational Model Of Trust Based On Dynamic Interaction In The Stack Overflow Community, Patrick O’Neill

Dissertations

A member’s reputation in an online community is a quantified representation of their trustworthiness within the community. Reputation is calculated using rules-based algorithms which are primarily tied to the upvotes or downvotes a member receives on posts. The main drawback of this form of reputation calculation is the inability to consider dynamic factors such as a member’s activity (or inactivity) within the community. The research involves the construction of dynamic mathematical models to calculate reputation and then determine to what extent these results compare with rules-based models. This research begins with exploratory research of the existing corpus of knowledge. Constructive …

The Use Of Data Balancing Algorithms To Correct For The Under-Representation Of Female Patients In A Cardiovascular Dataset, Sian Miller

Dissertations

Given that women are under-represented in medical datasets, and that machine learning classification algorithms are known to exhibit bias towards the majority class, the growing application of machine learning in the medical field risks resulting in worse medical outcomes for female patients. The Heart Failure Prediction (HFP) dataset is a historical dataset used for the training of models for the prediction of heart disease. This dataset contains significantly fewer female patients than male patients, and as such it is expected that models trained using this data will inherit a gender bias to favour male patients. This dissertation explores the use …

Probability Expressions In Ai Decision Support: Impacts On Human+Ai Team Performance, Elias Spinn

Dissertations

AI decision support systems aim to assist people in highly complex and consequential domains to make efficient, effective, and high-quality decisions. AI alone cannot be guaranteed to be correct in these complex decision tasks, and a human is often needed to ensure decision accuracy. The ambition is for these human+ AI teams to perform better together than either would individually. To realise this, decision makers must trust their AI partners appropriately, knowing when to rely on their recommendations and when to be sceptical. However, research has shown that decision makers often either mistrust and underutilise these systems, or trust them …

Shallow Subsurface Seismic Velocity And Event Location At The Apollo 17 Landing Site, Deanna Phillips

Dissertations

The origins of thermal moonquakes reveal insight into the evolution of the lunar surface through cyclic thermal stresses. While thermal moonquakes were observed during the passive Apollo 17 Lunar Seismic Profiling Experiment (LSPE), they have never conclusively been located. Using a shallow surface velocity model, thermal moonquakes can be located by minimizing the residual between the observed and theoretical travel times. The purpose of this study is to determine the source mechanism of thermal moonquakes to understand cyclic thermal stresses impacting lunar boulder breakdown. This study develops a location algorithm and explores the affects of various shallow surface velocity models. …

Understanding The Sequence Specificity Of Ribosome Arresting Peptides, Heather Nicole Gentle

Dissertations

Regulatory arrest peptides (RAPs) fine-tune gene expression based on physiological cues from internal and external environments. These peptides, generated from upstream open reading frames in bacteria and eukaryotes, function by conditionally arresting the ribosome to control the fate of associated messenger RNAs (mRNA). Commonly, RAPs contain two functional domains composed of conserved residues that are critical for ribosome arrest called the sensor and stalling domains. The sensor domain allows the peptide to monitor outside or within the ribosome for its inducer molecule by folding into secondary structures that produce a binding site. The stalling domain slows the rate of translation …
