Microfabrication Of Sic Using Femtosecond Lasers, Jared Eldon Payne

Theses and Dissertations

Silicon carbide (SiC) is a desirable material in a wide variety of semiconductor fields. The impressive thermal, chemical, and mechanical properties that make SiC an attractive material also make it very difficult to machine. New fabrication techniques are required to take full advantage of the potential of SiC. First, a new 3-dimensional (3D) non-line-of-sight (NLOS) fabrication technique using two-photon absorption is demonstrated in SiC. NLOS microchannels are shown with aspect ratios higher than 100:1. The process is the only method known, at this time, that can create truly 3D subsurface structures in SiC without direct line of sight to the …

Interfacial Phenomena In Molten Salt Systems And Wetting Transitions In Microcavities, Aaron Essilfie

Theses and Dissertations

Interfacial phenomena are the processes that occur at the interface between two phases of matter: solid-liquid, solid-gas, liquid-liquid, and liquid-gas. Wetting, spreading, adsorption, and capillarity are some features of interfacial phenomena. This research explores two areas of interfacial phenomena: the interfacial tension between a liquid and gas, and wetting transitions in microcavities. Surface tension has been a widely studied topic in surface chemistry. Many techniques have been employed to study the surface tension of liquids in various studies and research areas, but the interfacial tension between a liquid and gas has not been extensively researched. For this reason, part of …

Adapting Biological Mechanisms Into Machine Learning Structures And Gradient Propagation, Hao Yu

Theses and Dissertations

As neuromorphic computing gains traction, researchers look for learning schemes that are more suitable for brain-like structures. Although many algorithms have been discovered, such as surrogate gradient or Spike Timing Dependent Plasticity, those algorithms are either unsuitable for on-chip training or not biologically aligned. The goal of this thesis is to discover a learning algorithm which is biologically aligned and suitable for on-chip training. Through the discoveries of our two papers, we are able to introduce the concepts of synaptic clefts and neurotransmitters into a common spiking neuron network. We also designed an error propagation method aligning with biology. With …

Parental Strategies For Modifying Behavior: The Positives Of Positive Reinforcement, Benjamin D. Rasmussen

Intuition: The BYU Undergraduate Journal of Psychology

This research investigates the effectiveness of positive reinforcement as a central parenting strategy for modifying children’s behavior, grounded in B.F. Skinner’s operant conditioning theory. Using factor analysis, two key factors emerged: the impact of positive reinforcement on behavior change and its influence on parent-child dynamics. Positive reinforcement, which involves rewarding desirable behaviors with positive stimuli, has been found to promote the repetition of those behaviors and yield beneficial long-term outcomes. The evidence indicates that this approach not only strengthens desirable behaviors but also enhances the quality of relationships between parents and children, and teachers and students. Although some argue that …

Streamlined Production, Protection, And Purification Of Enzyme Biocatalysts Using Virus-Like Particles And A Cell-Free Protein Synthesis System, Seung O. Yang, Joseph P. Talley, Gregory H. Nielsen, Kristen M. Wilding, Bradley Charles Bundy

Faculty Publications

Enzymes play an essential role in many different industries; however, their operating conditions are limited due to the loss of enzyme activity in the presence of proteases and at temperatures significantly above physiological conditions. One way to improve the stability of these enzymes against high temperatures and proteases is to encapsulate them in protective shells or virus-like particles. This work presents a streamlined, three-step, cell-free protein synthesis (CFPS) procedure that enables rapid in vitro enzyme production, targeted encapsulation in protective virus-like particles (VLPs), and facile purification using a 6× His-tag fused to the VLP coat protein. This process is performed …

Using Unmanned Aerial Vehicles To Facilitate Traffic Incident Management, Adam William Hill

Theses and Dissertations

Incident management teams (IMTs) minimize crash impacts and create a safer highway network for people and communities. Research has shown that optimizing the IMT fleet has strong benefits to the roadway network, but future models indicate that increasing IMT presence may have diminishing returns after excessive roadway saturation. The Utah Department of Transportation (UDOT) would like to improve situational awareness in areas of poor or limited camera coverage, where situational awareness is typically poor. UDOT is considering the use of unmanned aerial systems (UAS) to provide live camera coverage of traffic conditions in these instances. This thesis synthesizes practice from …

The Connection Between Zermatt And Vail: How A Swiss Alpine Village Influenced The Creation Of A Colorado Village And Ski Resort In The Rocky Mountains, Thomas Quinn Marabello

Swiss American Historical Society Review

When one hears the places “Zermatt” and “Vail” we tend to think of skiing. Both are known worldwide for great skiing and beautiful mountains. While Zermatt has existed for centuries, Vail only became permanently inhabited by people after World War II. Zermatt did not become a well known place until the nineteenth century when adventurers sought to climb the Matterhorn, and then it became a popular tourist destination. However, Zermatt influenced the creation of the village of Vail, thanks to a man named Peter Seibert who spent time there and wanted to create a European Alpine style ski village in …

Literary Executor Of The Estate Of Christopher Dawson, Julian Scott

Comparative Civilizations Review

Christopher Dawson was a historian of religion and culture who wrote and lectured in England and America between the 1920s and his death in 1970. The author of this review, Dawson’s grandson and literary executor, argues not only that Dawson is very interesting to read as a historian, but also that many of his insights and proposals — such as his writing on European unity, nationalism, the consequences of a secularized culture and the conflict between humane individualism and state totalitarianism — remain highly relevant today. This article highlights some of Dawson’s most interesting and insightful ideas and aims to …

The Uses And Challenges Of Teaching Writing With Artificial Intelligence, Tom Henry

The Utah English Journal

Computers and Composition recently noted: “In less than a year, ChatGPT hit 100 million weekly users which made it the fastest-growing consumer Internet application to date. The ease, practicality, and ability to compose both in text and multimedia has made generative AI technology (like ChatGPT) ubiquitous” (Ranade and Eyman, 2024). Popularity aside, the question should be asked: Can students use AI ethically? A white paper from UNESCO puts forth the proposition that “Technology is never ideologically neutral… New generative AI models and utilities are no exception” (Giannini, 2023, p.3). Collating these claims, there are tasks where AI is ethical and …

How Companies Heal And Maintain Health: A Unique Function Of Corporate Museums In Japan, Aki Kinjo

Comparative Civilizations Review

Capitalism is embedded in our civilization. Despite its faults, weaknesses, and sins, modern civilization cannot prosper without capitalism. Companies are the engine of capitalism. Yet, just like humans, companies make mistakes, sometimes gross. How do companies overcome unforgivable mistakes? This paper argues that corporate museums in Japan play an important role in helping companies heal from their sufferings, recover, and maintain organizational health.

I deploy a cultural approach to management, analyzing corporate museums as a platform for conveying explicit and hidden narratives. A cultural approach to Japanese management helps us understand why Japan has so many corporate museums, well …

From Sonvilier To Canada To Illinois: A Remarkable Swiss Emigration Story, Jeanette Bowman Borich

Swiss American Historical Society Review

Author and genealogist Laurence Overmire stated, “History remembers only the celebrated, genealogy remembers them all.”¹ His words resonate as we consider the 1821 Swiss emigration to the Red River Settlement (in today’s Manitoba, Canada) followed by their subsequent emigration to the Galena, Illinois, area. Three recently published books on the history of Galena’s earliest days as a city² make no mention of the Swiss Red River families as early pioneers.³ A fourth book,⁴ Le Canada et les Suisses by E. H. Bovay, also relatively recently written, tells a different story. Genealogical research about one’s ancestors and …

Plants, Protests, Pachakuti: How Trees March And How People Tree, Ashley A. Lundquist

Theses and Dissertations

This thesis explores the multi-faceted role of plants, specifically Wituk and Manduru, in Amazonian protests and environmental advocacy. By examining the communicative and relational ontologies inherent in Runa culture, the study elucidates how plants influence social movements and contribute to environmental protection. Wituk and Manduru create paint. Paint facilitates good communication which creates good relationality. Good relationality allows for increased capacities and inhibits greedy consumption allowing for a balanced world order. Through the use and agency of Wituk and Manduru, movements become multi-species phenomena in which ecological entities combine with Runa bodies. The relationships shared between Runa, Wituk, and Manduru …

The Design And Cell-Free Protein Synthesis Of A Pembrolizumab Single-Chain Variable Fragment, Landon E. Ebbert, Tyler J. Free, Mehran Soltani, Bradley Charles Bundy

Pembrolizumab, a cancer immunotherapy drug, enables a strong T-cell response specifically targeting cancer cells to improve patient outcomes in more than 16 types of cancer. The increasing demand for pembrolizumab, the highest selling drug in 2023, increases global dependence on drug production, which can be vulnerable to supply chain disruptions. Methods: Cell-free protein synthesis (CFPS) is a rapid in vitro protein production method that could provide the production of an immunotherapy drug in an emergency and …

Transfer Learning For Thickener Control, Samuel Arce Munoz, John Hedengren

Faculty Publications

Thickener control is a key area of focus in the minerals processing industry, particularly due to its crucial role in water recovery, which is essential for sustainable resource management. The highly nonlinear nature of thickener dynamics presents significant challenges in modeling and optimization, making it a strong candidate for advanced surrogate modeling techniques. However, traditional data-driven approaches often require extensive datasets, which are frequently unavailable, especially in new plants or unexplored operational domains. Developing data-driven models without enough data representative of the dynamics of the system could result in incorrect predictions and consequently, unstable response of the controller. This paper …

Memory In Haruki Murakami's 'Norwegian Wood', Merry Ling

Theses and Dissertations

This thesis explores how Haruki Murakami's Norwegian Wood challenges conventional perceptions of memory as a linear process tied to self-understanding and reconciliation. Through the protagonist Toru Watanabe's struggle to confront his traumatic past, Murakami presents memory not as a straightforward tool for resolving the present but as an elusive, fragmented phenomenon. Toru's hesitance to release his attachment to the past, alongside his interactions with characters who embody different approaches to memory and trauma, underscores the complexity--and often the impossibility--of achieving closure. While the novel appears overwhelmed with tragedy, trauma, and loss, and offers no clear resolution for Toru, Murakami's subtle …

Origami Without Paper: Surrogate Folds For Origami-Inspired Mechanisms, Ivyann Oveson Running

Theses and Dissertations

Origami is a useful tool for generating novel spatial mechanisms that can address needs in a variety of fields. However, replicating paper folding in other materials requires surrogate folds---some way to approximate folding in otherwise rigid materials. This work presents a collection of potential surrogate fold designs suitable for use in origami-inspired applications. The designs are sorted into families and rated against several design characteristics of interest to engineers and designers to create the Surrogate Fold Catalog. The catalog is formatted to be searchable and filterable based on manufacturability, kinematic motion, and additional utility. Using this collection of surrogate folds …

Library/Life Sciences Undergraduate Poster Competition 2025

• Graves’ Disease (GD) is the 4th most common autoimmune disease in the United States.
• GD is characterized by autoreactive B cells releasing anti-thyroid stimulating hormone receptor (TSHR) Ab that bind to TSHR, causing an overexpression of hormones.
• Excessive hormonal release leads to hyperthyroidism, causing a variety of metabolic issues.
• No cure exists, only limited effectiveness of treatments, including chemotherapy, radiation, or thyroidectomy.
• Chimeric antigen receptors (CAR) T cell therapy has been effective in treating blood cancers.
• Modifying this therapy by engineering T cells that replace the antigen as the T cell receptor will selectively target autoreactive B cells, namely chimeric …

Laying Framework For A Novel System To Test Effects Of Histone Modifications, Taryn Evans, Luke Ramirez M.S, Aaron Bohn, Jacob Hunter, Sarah Hodson, Sarah Ricks, David Bates Ph.D, Steven M. Johnson Ph.D.

Library/Life Sciences Undergraduate Poster Competition 2025

Chromatin structure and composition play a significant role in regulating gene expression within eukaryotic cells. The fundamental organizational unit of chromatin is the nucleosome, which is composed of ~147 base pairs of DNA wrapped around a histone protein core. Post-translational modifications (PTM’s) to the protruding tails of histone proteins are known to regulate nucleosome occupancy and positioning, which influence chromatin architecture and thus gene expression. However, relatively little is known about the residual effects of histone PTM’s on transcription rate, especially in nucleosomes along the gene body. Here, we demonstrate a method for measuring transcription rate in real-time with a …

Fishing For Neurocircuitry: Identifying Multi-Sensory Integrating Neurons In The Optic Tectum Of Zebrafish, Logan Carson, Arminda Suli, Adeline Hamilton, Logan Carson, Karianne Jex, Erika C. Marks, Jordan T. Yorgason, Tracianne B. Neilsen

Library/Life Sciences Undergraduate Poster Competition 2025

The superior colliculus (SC) is a mammalian midbrain structure involved in multimodal sensory integration and is implicated to have a role in neurodevelopmental disorders. Although the presence of multisensory integrating neurons (MINs) in the SC has been well documented by electrophysiology techniques, little is known about their morphological or molecular characterization. To identify and study MINs, we utilized SC’s non-mammalian homologous structure–the optic tectum (OT)–in the genetically tractable model organism zebrafish. In this process, we generated transgenic lines that allowed for fluorescent detection of neuronal activity by expressing the genetically engineered calcium indicators: cytoRGECO and H2B-jRGECO1a, respectively in mechanosensory hair …

The Lamb Of God: A Note On The Significance Of Meir Bar-Ilan’S Paper For Latter-Day Saints, Jeff Lindsay

Interpreter: A Journal of Latter-day Saint Faith and Scholarship

Dr. Meir Bar-Ilan’s paper, “The Heavenly Lamb, Sacrifices on the Heavenly Altar, and the Song of the Lamb,” appearing concurrently in Interpreter, is a welcome contribution from a noted Jewish scholar. Bar-Ilan has called the world’s attention to a remarkable Hebrew manuscript with origins in antiquity, Words of Gad the Seer. Those interested in the relationship between Jewish texts and Latter-day Saint scriptures may also wish to compare the findings in Bar-Ilan’s paper with treatments of the Lamb of God in the Book of Mormon and the Book of Moses.

Customer Service Operations: A Gatekeeper Framework, Maqbool Dada, Brett A. Hathaway, Evgeny Kagan

Faculty Publications

Customer service has evolved beyond in-person visits and phone calls to include live chat, AI chatbots and social media, among other contact options. Service providers typically refer to these contact modalities as “channels”. Within each channel, customer service agents are tasked with managing and resolving a stream of inbound service requests. Each request involves milestones where the agent must decide whether to keep assisting the customer or to transfer them to a more skilled – and often costlier – provider. To understand how this request resolution process should be managed, we develop a model in which each channel is represented …
