Theses and Dissertations

Cobalt(II) scorpionates possess distinct electronic and magnetic properties in comparison to other first-row transition metal complexes in this ligand class. One unique property is their significantly downfield paramagnetically shifted 11B NMR signals. The utilization of a heteroscorpionate ligand Tp’ introduces asymmetry to metal scorpionates, producing cis and trans isomers. cis- and trans-Co(Tp’)2 were synthesized and separated by column chromatography. 11B NMR data show cobalt(II) homoscorpionates resonances in a narrow 20 ppm shift range around 270 ppm while cis- and trans-Co(Tp’)2 differ with signals at 230 ppm and 140 ppm, respectively. Paramagnetic NMR studies indicate both isomers maintain the same spin …

Optimal Stopping And Related Topics, Jackson Scott Hebner

View Dependent Simplification And Tessellation For Real-Time High Quality Rendering Of 3d Meshes, Dallin M. Hagman

Theses and Dissertations

The increasing complexity of 3D meshes and growing disparity in performance between high and low-end hardware necessitates more efficient rendering techniques that do not sacrifice visual quality. To support as many hardware configurations as possible, producers of 3D content provide several resolutions of each mesh. Low-end hardware is typically restricted to low-resolution meshes to maintain performance similar to their high-end counterparts, sacrificing visual appeal. However, the presence of hardware tessellation in nearly all modern GPUs presents the opportunity to render high-resolution versions of simplified meshes on low-end hardware with little computational cost. Some research has been conducted into this opportunity, …

Wiener Index In Graphs Given Girth, Minimum, And Maximum Degrees, Fadekemi J. Osaye, Liliek Susilowati, Alex S. Alochukwu, Cadavious Jones

Theory & Applications of Graphs

Let $G$ be a connected graph of order $n$. The Wiener index $W(G)$ of $G$ is the sum of the distances between all unordered pairs of vertices of $G$. The well-known upper bound $\big( \frac{n}{\delta+1}+2\big) {n \choose 2}$ on the Wiener index of a graph of order $n$ and minimum degree $\delta$ by Kouider and Winkler \cite{Kouider} was improved significantly by Alochukwu and Dankelmann \cite{Alex} for graphs containing a vertex of large degree $\Delta$ to $W(G) \leq {n-\Delta+\delta \choose 2} \big( \frac{n+2\Delta}{\delta+1}+4 \big)$. In this paper, we give upper bounds on the Wiener index of $G$ in terms of order …

Using Quantitative And Kinetic Proteomics To Explore Proteostasis, Nathan Raul Zuniga Pina

Theses and Dissertations

Every cell consists of carefully orchestrated biomolecules such as lipids, carbohydrates, and proteins. To maintain internal stability (homeostasis), cells maintain the right amount of these molecules at the right time and at the right place. This process is especially true for proteins since they are the foundation functional units within the cell. Proteins form structures and perform chemistry that bestows cells overarching functional roles. Cells maintain protein homeostasis (proteostasis) by modulating synthesis, folding, and degradation processes (turnover) to maintain the abundance levels for all proteins. This is the foundational kinetic model of proteostasis that is covered in this work, and …

Is Your Computer Lying? Ai And Deception, Noreen L. Herzfeld

Reuter Professorship of Science and Religion Publications

Recent developments in AI, especially the spectacular success of Large Language models, have instigated renewed questioning of what remains distinctively human. As AI stands poised to take over more and more human tasks, what is left that distinguishes humans? One way we might identify a humanlike intelligence would be when we detect it telling lies. Yet AIs lack both the intention and the motivation to truly tell lies, instead producing merely bullshit. With neither emotions, embodiment, nor the social awareness that leads to a theory of mind, AIs lack the internal referents on which to judge truth or falsity. When …

A Generalized Kodaira Vanishing Theorem For Lie Algebroids And A Riemann–Roch Theorem For Singular Foliation, Tengzhou Hu

Arts & Sciences Graduate Student Theses and Dissertations

A Lie algebroid is a generalization of Lie algebra that provides a general framework to describe the symmetries of a manifold. In this thesis, we first generalize the Kodaira vanishing theorem, which is a basic result in complex geometry, to K\"{a}hler Lie algebroids. The generalization of the Kodaira vanishing theorem states that the kernel of the Lie algebroid Laplace operator on Lie algebroid positive line bundle-valued $(p,q)$-forms vanishes when $p+q$ is sufficiently large. The most difficult part of the proof of the generalized Kodaira vanishing theorem is the generalization of the K\"{a}hler identities to Lie algebroids. Secondly, we introduce Lie …
