Parental Influence On Adolescent Perfectionism, Jenet Erickson, Olivia Forsberg, Mckenna Schmidt Jan 2024

Parental Influence On Adolescent Perfectionism, Jenet Erickson, Olivia Forsberg, Mckenna Schmidt

BYU Studies

I (primary author) will never forget a poignant moment in the mother’s lounge at church when our first child was about nine months old. Two other mothers with younger babies were in the lounge at the same time, and we talked as our babies nursed, then played. As I watched the two younger children crawl around, I became acutely aware that our daughter, who had not yet started to crawl, was clearly behind these other children. A panicky feeling overtook me as I wrestled with what it meant to me that these children appeared to be ahead of mine. I …

Response To Grant Wacker, Richard Lyman Bushman Jan 2024

Response To Grant Wacker, Richard Lyman Bushman

BYU Studies

As so often happens when Latter-day Saint historians discuss Joseph Smith with their non-LDS compatriots, Grant Wacker wants to welcome Joseph Smith into the company of American prophets, while I insist that Smith is bizarre, strange, and other. Wacker sees Smith as a recognizable figure on the American religious landscape; I see him as an outlander notably because he presented himself initially as a translator. I admit it had never occurred to me to think of Pentecostal speakers in tongues as translators, but of course they were. It seemed a natural connection to Wacker, who is deeply conversant in Pentecostal …

Love Is A Law, Not A Reward, Adam S. Miller Jan 2024

Love Is A Law, Not A Reward, Adam S. Miller

BYU Studies

1. Love is the substance of God’s law. As Paul puts it: “If there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself ” (Rom. 13:9). Or, as Jesus summarizes the law: “On these two commandments”—love of God and love of neighbor—“hang all the law and the prophets” (Matt. 22:40). What’s more, this love can’t be treated as a special reward. “Ye have heard that it hath been said,” Jesus acknowledges, “thou shalt love thy neighbour, and hate thine enemy. But I say unto you, Love your enemies” (Matt. 5:43–44). …

Diagnostics Development For And Study Of Energetic Materials Subject To Shock Loading, Robert Ichiyama Jan 2024

Diagnostics Development For And Study Of Energetic Materials Subject To Shock Loading, Robert Ichiyama

Open Access Dissertations

A wide range of shock physics experiments require a high pressure, 2D-planar shock with pressure and temporal uniformity. Researchers, traditionally, would utilize a gas gun facility or high explosive plane wave lens. These techniques have several limitations. Gun facilities have high facility cost and long experiment times. Legacy fast-slow explosive lenses require labor intensive and high risk, high precision pressed or casted and, subsequently, machined explosives. Any design changes made with the explosives in such traditional lenses leads to significant increases in cost and time. Previous groups demonstrated that inert waveguides can generate a planar shock using only a single …

Interactions Of Caffeine With Anticancer Drugs Studied By Nuclear Magnetic Resonance, Baylee Parish Jan 2024

Interactions Of Caffeine With Anticancer Drugs Studied By Nuclear Magnetic Resonance, Baylee Parish

Theses

Caffeine can form stacking through pi-pi interactions with aromatic anticancer drugs. While caffeine can reduce the toxicity of the anticancer drugs, caffeine can also reduce the efficacy of the anticancer drugs. Aromatic anticancer drugs, such as daunorubicin and irinotecan, work by intercalating into DNA. When caffeine binds to an anticancer drug, the new complex formed cannot easily intercalate into DNA strands. Through Nuclear Magnetic Resonance (NMR) spectroscopy, chemical shift values for pure caffeine, daunorubicin, and irinotecan, as well as, caffeine mixed with daunorubicin and irinotecan were analyzed. Different concentrations for the pure compounds and the mixtures were analyzed by NMR. …

Small Molecule Modulation Of The P75 Neurotrophin Receptor Attenuates Neurodegeneration In An In Vitro Model Of Parkinson’S Disease, Poshan Pokharel Jan 2024

Small Molecule Modulation Of The P75 Neurotrophin Receptor Attenuates Neurodegeneration In An In Vitro Model Of Parkinson’S Disease, Poshan Pokharel

Theses

The p75 Neurotrophin Receptor (p75NTR) is a multifunctional transmembrane protein expressed in distinct regions of the adult nervous system. p75NTR regulates various functions, including neuronal survival or apoptosis interacting with coreceptors Trk receptors or sortilin. Activation of p75NTR occurs through proteolytic processing, and we previously demonstrated that oxidative stress induces activation of p75NTR in LUHMES cells, a neuronal cell line derived from the human ventral mesencephalon. Dopaminergic neurons of the ventral mesencephalon are vulnerable to oxidative stress and neurodegeneration associated with Parkinson’s disease (PD). Thus, we evaluated the mechanisms behind p75NTR activation and its physiological implications in a PD model. …

Spectral Deconvolution Using Machine Learning For Determining Material Compositions In Mixed Samples, Prakash Chaudhary Jan 2024

Spectral Deconvolution Using Machine Learning For Determining Material Compositions In Mixed Samples, Prakash Chaudhary

Theses

Hyperspectral unmixing is essential in determining material compositions in mixed samples with a larger number of endmembers, but achieving precise decom- position remains challenging due to the limited work done, the presence of spectral variability, and endmember complexities. This study proposes many machine learning methods and techniques to identify the material composition in mixed samples (composites). Other methods to solve this problem mainly focus on a very small number of endmembers; our approach works with many end members, improving the model’s robustness. The proposed methods effectively tackle spectral variability, high dimensionality, and the presence of similar endmembers by integrating a …

Data Remanence Vulnerabilities In Embedded Sram At Low Temperature, Farzana Hoque Jan 2024

Data Remanence Vulnerabilities In Embedded Sram At Low Temperature, Farzana Hoque

Theses

Static Random Access Memory (SRAM) memory is prevalent as cache memory in computing platforms and embedded systems. SRAM frequently stores essential information such as cryptographic keys, passwords, and other confidential data. Consequently, a data remanence-based attack on SRAM can result in significant damage. When power is removed, SRAM gradually loses data rather than immediately, especially at lower temperatures. This phenomenon, known as data remanence, poses a significant security risk, as it can be exploited through cold boot attacks targeting encryption keys and other sensitive data. Understanding temperature-induced vulnerabilities in embedded SRAM is crucial for enhancing the security and reliability of …
