Kyle ML Jones, Kristin Briney, Abigail Goben, Dorothea Salo, Andrew Asher & Michael Perry
Universities are pursuing learning analytics practices to improve returns from their investments, develop behavioral and academic interventions to improve student success, and address political and financial pressures. Academic libraries are additionally undertaking learning analytics to demonstrate value to stakeholders, assess learning gains from instruction, and analyze student-library usage, among other things. The adoption of these techniques leads to many professional ethics issues and practical concerns related to privacy. In this narrative literature review, we provide...

Glycosylation and Sialylation During Wound Healing

Veronica A Haywood
Chronic wounds significantly increase morbidity and mortality and are a consequence of disease including diabetes. Previous studies have demonstrated that glycosylation, a post- translational protein modification whereby carbohydrates are added to proteins, is altered during corneal wound healing and in diabetes. However, no studies have examined whether differential glycosylation occurs during wound healing between different tissue types, in diabetic skin wound healing, and/ or among tissues with different healing potentials. Since the skin exhibits impaired...

Improving Accuracy of In-SRAM Binary Precision Neural Network by Support Vector Optimization

Over the past few years, there has been an increasing demand for low power and high performance machine learning particularly, for large scale deployment of Neural Network systems on hardware platforms due to the requirement of large volumes of data and growing complexity of network architectures. Frequent off-chip memory accesses during multiply and accumulate operations cause the bottleneck in achieving high power efficiency. There have been many near-data processing techniques being proposed but they fall...

Method Validation of Methamphetamine and its Metabolites in Equine Urine

Kristen Joy Prieto
Various precision studies were performed to validate this analysis method using negative control equine urine and standards of the target compounds; methamphetamine, amphetamine, hydroxyamphetamine, hydroxymethamphetamine, and phenylpropanolamine. Initial studies also led to changing the extraction method from liquid-liquid to solid-phase. Once the precision studies were acceptable three independent sets of administered samples obtained from horses dosed with methamphetamine, hydroxyamphetamine, and phenylpropanolamine respectively, were extracted and analyzed using the method. The samples were taken over a...

Mathematical Results for Nonlinear Equations of Schrödinger Type

Jack Austin Arbunich
The content of this thesis encapsulates four results in the analysis of nonlinear partial differential equations of Schrödinger type. These mathematical models are motivated by phenomena in laser optics and quantum physics, and the works themselves demonstrate several mathematical techniques frequently employed to understand properties of such models. In the first two works, we prove global well-posedness of models for laser propagation at high intensities in which off-axis variations in the group velocity and self-steepening...

The Influence of Race and Sex on the Peak Blood Pressure Response to Exercise

Ahmad Samir Sabbahi
Hemodynamics during exercise is an important physiologic response that is associated with risk prediction and diagnosis of latent cardiovascular disease and independent of resting blood pressure (BP). Individuals who exhibit an exaggerated BP response to exercise, also known as exercise HTN (defined as a reading 90th percentile from relative normative data), have been shown to possess a 1.4 to 3.0 fold higher relative risk for cardiovascular events compared to subjects with a normal BP response...

As a result, a greater emphasis has been placed on endovascular simulation to accelerate skill acquisition at each level of training. The quality, validity and outcomes of endovascular simulation research have been poorly addressed. Aim: The aim of this study is to...

Rainfall and Turbidity as Simple Alternative Predictors of Beach Water Quality in Chicago

Kendall Wayne Anderson
Monitoring beach water quality is an essential component in protecting recreator health and preventing gastrointestinal illness at beaches. Historically, laboratory methods used for monitoring bacteria required at least 18-24 hours before the public could be notified of water quality conditions. This gap period of 18-24 hours led to inaccuracies of current water quality conditions at beaches, as these methods assessed conditions of the day prior. These methods are still used by monitoring programs across the...

Septin2 Mediated Maturation of Endothelial Podosomes is Required for Angiogenesis

Kerrie B Collins
Podosomes are compartmentalized actin-rich adhesions, defined by their ability to locally secrete proteases and remodel extracellular matrix. Matrix remodeling by endothelial podosomes facilitates invasion, and thereby vessel formation. However, the mechanisms underlying endothelial podosome formation and function remain unclear. Here we demonstrate that Septins2, 6, and 7 are required for maturation of nascent endothelial podosomes into matrix degrading organelles. We show that podosome development occurs through initial mobilization of the scaffolding protein Tks5 and F-actin...

2D/3D Heterostructure Interface Design and Property Modification

Chen Wang
2D/3D Heterostructure Solar Cells have attracted numerous attention due to its potential to be an alternative to the silicon (Si) Wafer-based photovoltaic technologies. However, most 2D/3D Heterojunction photovoltaic cells suffer from long-term instability in power conversion efficiency. This is mainly due to the interfacial charge carrier recombination owing to the low 2D/3D built-in electric field. Therefore, it is critical to overcome these challenges via interfacial engineering. Here in my thesis, I have introduced 2D thin...

Cysteine Protease Inhibitors for the Treatment of Neurodegenerative Diseases and Osteoporosis

Ammar Jastaniah
Our lab has previously synthesized peptidomimetic cysteine protease inhibitors that are efficacious in mice models of Alzheimer's Disease.9 However, because they possess the highly reactive oxirane warhead, they exhibited high off-target effect as well as poor selectivity, as evidenced by their inhibition of the promiscuous cysteine protease, papain. Hence, in addressing such issues, we shifted our focus to the synthesis of reversible inhibitors, namely those that contain nitrile and α-ketoamide warheads. For both types of...

Structural Studies on Modular Sensory Proteins

The abilities to sense, respond, and adapt to environmental changes in various physical and chemical stimuli are essential for living organisms. Signaling proteins establish an intricate signaling network to ensure prompt and precise signal transduction from point A to B within a cell or from cell to cell. The primary function for a signaling protein is to relay information gathered from the internal or external environment to promote specific cellular processes, many of which are...

School Choice Policies and Market Competition: Implications for the Public Education Sector

Rui Yan
This dissertation studies the effect of school choice policies with a focus on charter schools and school vouchers. Exploiting the time-varying charter competition driven by the Michigan 2011 cap-lifting policy, the first chapter examines the effect of charter competition on traditional public school districts’ cost efficiency in two ways. The first part estimates the effect of the cap-lifting policy on districts’ resource allocation. The second part extends the policy analysis to disentangle the separate effects...

Accurate Time Series Classification Using Deep Learning and Partial Observations

Over the past decade, there has been a significant increase in interest in classifying time series data. Typically, there are two objectives of classifying time series data, efficiency (speed) and effectiveness (accuracy). In this dissertation, we propose a framework to detect optimal partial observations to classify time series data. Further, we propose a few deep learning architectures to improve the classification accuracy of univariate and multivariate time series data. Finally, we present an architecture that...

Exploitation of Nitrone and Hydroxylamine N–O Bonds for the Construction of Functionalized Heterocycles

Tyler W Reidl
In the Anderson group at UIC, we aim to develop new transformations involving N-vinylnitrone and N,O-divinylhydroxylamine intermediates to access functionalized molecules and novel heterocyclic scaffolds by harnessing the reactivity of N–O bonds. Recently, we have expanded the scope of these methods to include the synthesis of azetidine nitrones through the 4π-electrocyclization of N-vinylnitrones, and we have also laid the foundation for asymmetric catalysis of this transformation to access stereodefined azetidine precursors. These azetidine nitrones have...

The Effects of Hypercholesterolemia on Wound Healing and Angiogenesis

Hypercholesterolemia, a nationwide problem, is excess cholesterol in the bloodstream, including both excess LDL and oxLDL. The true issue with hypercholesterolemia is the possible, adverse cardiovascular outcomes, such as myocardial infarction or stroke. This dissertation investigates how hypercholesterolemia affects endothelial cells and angiogenesis both in vitro and in vivo. These studies serve to show that exposing endothelial cells to hypercholesterolemic conditions, elevated levels of LDL similar to those seen in hypercholesterolemic patients, leads to cholesterol...

Stability of Universal Constructions for Persistent Homology

Janis Lazovskis
In this thesis I describe poset stratifications of the product of the Ran space and the nonnegative real numbers, as a universal space for the Cech construction of simplicial complexes. This leads to a cosheaf valued in diagrams of simplicial complexes for which every restriction to a finite collection recovers the persistent homology of the collection. For the stratification, I describe a partial order on isomorphism classes of abstract simplicial complexes, which allows spaces stratified...

Addressing the Gap Between Recommended Infant Care Practices and Reality Using the Ecological Framework

Hillary Louise Rowe
The Theory of Planned Behavior (TPB; Ajzen, 1991) has been applied to breastfeeding and infant safe sleep practices to understand why some parents do not follow the American Academy of Pediatrics recommendations. This theory has limited usefulness for these behaviors, however, because it does not account for the dynamic nature of these behaviors over time. The current study addressed this limitation by assessing the TPB constructs and then applying principles from the Ecological Framework (Trickett,...
