Synthesis Of Functionalized Aromatic Heterocyclic Compounds And Its Applications In Organized Self-Assemblies, Emmanuel T. Fasusi
Synthesis Of Functionalized Aromatic Heterocyclic Compounds And Its Applications In Organized Self-Assemblies, Emmanuel T. Fasusi
Electronic Theses and Dissertations
1,2,3-triazoles due to their structure, possess good optical properties and are capable of molecular recognition by their supramolecular capabilities of utilizing weak forces of interaction (such as hydrogen bonding, dipole interaction) in establishing a close association with targets. They are easy to synthesize, which opened the opportunity for a wide pharmaceutical application, mostly as pharmacological scaffolds. However, challenges such as poor water solubility, inefficient drug delivery and increased toxicities due to frequent dosing of drugs are commonly faced which reduces the efficacy of the drugs. It is therefore important to have “delivery vehicles” which could help transport the drugs to …
Evaluation Of Tidal Fresh Forest Distributions And Tropical Storm Impacts Using Sentinel-2 Msi Imagery, Galen Costomiris
Evaluation Of Tidal Fresh Forest Distributions And Tropical Storm Impacts Using Sentinel-2 Msi Imagery, Galen Costomiris
Electronic Theses and Dissertations
Situated in the transitional zone between non-tidal forests upstream and tidal fresh marshes downstream, tidal fresh forests occupy a unique and increasingly precarious habitat. The threat of intensifying anthropogenic climate change, compounded by the effects of historical logging and drainage alterations, could reduce the extent of this valuable ecosystem. The overall goals of this project were to identify forest communities present in the Altamaha tidal fresh forest; develop satellite imagery-based classifications of tidal fresh forest and tidal marsh vegetation along the Altamaha River, Georgia; and to quantify changes in vegetation distribution in the aftermath of hurricanes Matthew and Irma. Based …

Understanding And Harnessing The Structural Features That Govern Hmg-Coa Reductase Activity, Edwin Ragwan
Understanding And Harnessing The Structural Features That Govern Hmg-Coa Reductase Activity, Edwin Ragwan
Bryn Mawr College Dissertations and Theses
The enzyme 3-hydroxy-3-methylglutaryl coenzyme-A reductase (HMGR), which catalyzes the reduction of HMG-CoA to mevalonate using two equivalents of the cofactor NAD(P)H, is part of the mevalonate pathway, found in all kingdoms of life. This pathway is at the heart of natural product biosynthesis constituting one of the obligate routes to producing the building blocks for isoprenoids, which represent the largest and most diverse class of natural products. Natural products and its derivatives continue to provide important compounds in the fields of drug development, biomedical engineering, and commercially-driven products. Therefore, HMGR, which performs the rate-limiting step of the mevalonate pathway garners …
Applying Intensity-Based Methods To Disentangle Microwave Spectra Of Complex Mixtures: Analysis Of Weakly Bound Clusters Of 1,1-Difluoroethylene/Co2, Hannah Fino
Masters Theses
Microwave spectroscopy is used to study the solvent-solute interactions between molecules of CO2 and fluoroethylenes by analyzing the formation of weakly-bound clusters in a gaseous mixture. One of the challenges to analyzing microwave spectra obtained for these weakly-bound species is that spectra for individual clusters are mixed together in an original complex spectrum. This prompts development of automated techniques that could separate complex data into subsets of related data to be more easily analyzed.
The techniques developed in this work are founded on intensity-based analyses, following the work of Dr. Robert Field on Extended Cross Correlation (XCC). The XCC …

Producers were also asked about their worldviews and values. Together, these questions help provide an understanding of the cultural state of the Ogallala aquifer, especially as it pertains to groundwater use.
U-Pb Apatite Chronometry Of Intrusions In An Accretionary Metamorphic Belt In Western Idaho, Usa, Colleen Grace Rankin
U-Pb Apatite Chronometry Of Intrusions In An Accretionary Metamorphic Belt In Western Idaho, Usa, Colleen Grace Rankin
MSU Graduate Theses
The Salmon River suture zone in west-central Idaho, USA records the tectonic processes where island arcs, similar to modern-day Japan, were accreted to the North American continent in the Jurassic and Cretaceous periods (160-90 million years ago). This suture zone contains metamorphic rocks that were buried deep within the crust at depths of 20 kilometers or more and have subsequently been brought to the surface. The exhuming processes responsible for the metamorphic rocks in the Salmon River suture zone remains unclear. Two competing hypotheses have been proposed to explain the transport of the rocks from the Salmon River suture zone …
Khovanov Homology & Uniqueness Of Surfaces In The 4-Ball, Isaac Sundberg
Khovanov Homology & Uniqueness Of Surfaces In The 4-Ball, Isaac Sundberg
Bryn Mawr College Dissertations and Theses
We use the functoriality of Khovanov homology to examine the smooth, boundary-preserving isotopy of surfaces embedded in the 4-ball. We exemplify an infinite family of prime knots that bound an arbitrarily-large number of smoothly-distinct slice disks by distinguishing the maps they induce on Khovanov homology. Similar techniques produce an infinite family of knots that each bound a pair of exotic surfaces of arbitrary genus.
Distribution Of Holonomy About Closed Geodesics On Compact Hyperbolic 3-Manifolds, Lindsay Dever
Distribution Of Holonomy About Closed Geodesics On Compact Hyperbolic 3-Manifolds, Lindsay Dever
Bryn Mawr College Dissertations and Theses
An important feature of compact hyperbolic 3-manifolds is their closed geodesics, which have both geometric and dynamical implications. These geodesics are parametrized by their length and holonomy, which describes the angle of rotation by parallel transport about the geodesic. First, we prove ambient prime geodesic theorems, which provide an asymptotic count of closed geodesics by their length and holonomy and imply e ective equidistribution of holonomy in shrinking intervals. These theorems result from a non-spherical Selberg's trace formula which relates spectral information to lengths and holonomies of closed geodesics. Then, we show that although holonomy is equidistributed, there is typically …

In this paper, we will show our findings, analyze their accuracy, and define a system capable of deriving this data with near-human accuracy in a fraction of the time. Denoising techniques applicable to this system will be discussed, as will our discoveries and findings. Finally, suggestions for further research opportunities will be provided.
Measurement Of (Alpha, Neutron) Reactions And Development Of Analysis Tools With The Majorana Demonstrator, Tupendra Kumar Oli
Measurement Of (Alpha, Neutron) Reactions And Development Of Analysis Tools With The Majorana Demonstrator, Tupendra Kumar Oli
Dissertations and Theses
Neutrinoless double-beta decay (0νββ) is a hypothetical nuclear transition which, if observed, would prove that neutrinos are Majorana particles. In addition, the decay rate could provide an effective neutrino mass scale. The decay violates lepton number conservation and could offer a potential path to explain the matter-antimatter asymmetry in the universe via leptogenesis. However, the experimental observation of this decay is very challenging and would require excellent energy resolution of detectors, low background levels, and high exposure. The MAJORANA DEMONSTRATOR experiment searches for this decay in 76Ge using P-type Point Contact (PPC) High Purity Germanium (HPGe) detectors. In addition, the …
Framework For The Evaluation Of Perturbations In The Systems Biology Landscape And Inter-Sample Similarity From Transcriptomic Datasets — A Digital Twin Perspective, Mariah Marie Hoffman
Framework For The Evaluation Of Perturbations In The Systems Biology Landscape And Inter-Sample Similarity From Transcriptomic Datasets — A Digital Twin Perspective, Mariah Marie Hoffman
Dissertations and Theses
One approach to interrogating the complexities of human systems in their well-regulated and dysregulated states is through the use of digital twins. Digital twins are virtual representations of physical systems that are descriptive of an individual's state of health, an object fundamentally related to precision medicine. A key element for building a functional digital twin type for a disease or predicting the therapeutic efficacy of a potential treatment is harmonized, machine-parsable domain knowledge. Hypothesis-driven investigations are the gold standard for representing subsystems, but their results encompass a limited knowledge of the full biosystem. Multi-omics data is one rich source of …
Assessing The Effects Of Instream Large Wood On Floodplain Aquifer Recharge And Storage At Indian Creek, Kittitas County, Washington, Usa, Stephen Bartlett
Assessing The Effects Of Instream Large Wood On Floodplain Aquifer Recharge And Storage At Indian Creek, Kittitas County, Washington, Usa, Stephen Bartlett
All Master's Theses
Numerous stream restoration projects in the Yakima River Basin in Washington have placed large wood (LW) into tributary channels. One intended effect is to divert water onto floodplains to increase groundwater (GW) recharge and seasonal storage in shallow alluvial aquifers during spring high flows with the intention of releasing GW into streams during the drier summer months. Large wood was emplaced in the Indian Creek tributary of the Teanaway River in Kittitas County, Washington beginning in 2016. Potential changes in the groundwater recharge in the adjacent floodplain before and after the LW installation were investigated through stratigraphic analysis, stream-flow modeling, …
Assessing The Mechanics Of Two Earthquake Clusters In The Basin And Range Province, Jamie Hansen
Assessing The Mechanics Of Two Earthquake Clusters In The Basin And Range Province, Jamie Hansen
All Master's Theses
The seismicity in the Basin and Range Province of the western United States often manifests as clusters of earthquakes occurring over brief windows of time, lasting from months to years. Two different earthquake clusters occurring between 2014 and 2018, near Challis, Idaho and northwestern Nevada, were assessed in this study. The seismic activity in the southeastern section of the Challis cluster began with a M5.2 earthquake that was likely the main-shock earthquake in an aftershock sequence. The northwestern section of the Challis cluster does have several potential candidates for a main-shock earthquake, but none have been identified as a start …

Privacy Concerns With Using Public Data For Suicide Risk Prediction Algorithms: A Public Opinion Survey Of Contextual Appropriateness, Michael Zimmer, Sarah Logan
Computer Science Faculty Research and Publications
Purpose
Existing algorithms for predicting suicide risk rely solely on data from electronic health records, but such models could be improved through the incorporation of publicly available socioeconomic data – such as financial, legal, life event and sociodemographic data. The purpose of this study is to understand the complex ethical and privacy implications of incorporating sociodemographic data within the health context. This paper presents results from a survey exploring what the general public’s knowledge and concerns are about such publicly available data and the appropriateness of using it in suicide risk prediction algorithms.

Exploration Of Light-Driven, Zirconium Catalyzed Hydrophosphination And Progress Towards Asymmetric Hydrophosphination, Bryan Teixeira Novas
Exploration Of Light-Driven, Zirconium Catalyzed Hydrophosphination And Progress Towards Asymmetric Hydrophosphination, Bryan Teixeira Novas
Graduate College Dissertations and Theses
Direct irradiation of UV or visible light on zirconium catalyzed hydrophosphination reactions have shown to improve relative reaction rate and unlock new reactivity in contrast to reactions run in ambient light or the exclusion of light. The fist compound observed to receive this benefit was a triamidoamine-supported zirconium complex abbreviated (N3N)Zr that has been extensively studied by our group. UV-vis spectroscopy and TD-DFT calculations of early experiments revealed the nature of this improved reactivity being the population of an excited state that exhibits significant Zr–P σ* character in the active catalyst upon photon absorbance. This nd charge transfer elongates the …
