Vanishing white matter (VWM) is a rare disorder, characterized by degeneration of CNS white matter, clinically often exacerbated by stressors such as fever and minor head trauma. VWM is caused by biallelic pathogenic variants in the EIF2B1-5 genes, causing reduced activity of eukaryotic initiation of translation factor 2B, resulting in dysregulation of the integrated stress response (ISR). New scientific insights and increased clinical trials in experimental therapies highlight the need for clinical guidelines to improve and standardize care for patients with VWM worldwide. Standardized care is important for therapy development, as it lessens clinical variability of trial participants at study …

Modeling Private Debt Using U.S. Consumer Expenditure Data, Stsiapan Dziamentsyeu

Honors Capstones

This project models private household debt among U.S. consumers using data from the Consumer Expenditure Survey (CES) between 2013 and 2023. The analysis focuses on identifying how demographic and economic characteristics, such as income, housing expenditures, education, and occupation, relate to non-mortgage “other” loan balances. After initial model development produced poor residual behavior due to zero-inflation from imputed debt values, the analysis was refined to include only households reporting verifiable debt. Multiple modeling techniques, including AIC-based variable selection and Lasso regularization, were compared under a five-fold cross-validation framework. The Lasso model achieved superior predictive accuracy (RMSE = 1.55, MAE = …

The Association Between Loneliness And Mental Health In Underserved Communities, Ameemah Khan, Yu-Ping Chang

Biennial Convention (CONV)

Background: Loneliness is a distressing emotional state that arises when an individual's actual social relationships do not align with their desired social connections. As loneliness becomes increasingly prevalent among adults, its adverse effects on mental health have grown more evident. Research links loneliness to poor sleep quality, suicidal ideation, severe depressive symptoms, and heightened stress. These effects are particularly pronounced in underserved communities, where social determinants of health disproportionately impact African Americans, contributing to poorer health outcomes. However, limited research explores the relationship between loneliness, sleep, and depression specifically within African American populations.

Purpose: This study aims to determine whether …

The Patient Violence Framework, Laura Graham, Jennifer Bail

Biennial Convention (CONV)

Patient Violence against nurses is a widespread problem resulting in both emotional and physical injury to the nurse. Emergency Department (ED) nurses are at an increased risk due to the volume and variety of the patients they serve, and the general chaotic environment of the ED; however, little research has been done examining the characteristics of patients who offend and the physical environment of the ED where the event happened. The aim of this three-article dissertation was to develop a more thorough understanding of the personal attributes (endogenous) of the individual patient and external (exogenous) factors of the ED setting …

Orbital Reliable Printed Circuit Boards, Thomas Maxwell Starnes, Keegan Blake Jordan, Ian Griffith, Grant Monroe Pesqueira, Vishal Navin Patel

Senior Design Project For Engineers

Deep Interstellar Solutions is proposing a device to produce custom, serviceable printed circuit boards (PCBs) in low Earth orbit. This technology uses blank PCBs that are laser-etched and prepared for electrical components, then stored in the module. This method of PCB production allows for rapid repairs or prototyping without the need for subsequent resupply missions. By implementing this technique, future missions will achieve greater autonomy, sustainability, and resource efficiency. The goal of this development is to pioneer the creation of custom circuitry for use in deep-space missions where resupply is neither cost-effective nor timely.

Data For "Large Projected Increases In Area Burned And Wildfire Frequency By 2050 In Utah, Usa", Joseph D. Birch, Yoshimitsu Chikamoto, James A. Lutz

Browse all Datasets

Changes in wildfire regimes may disrupt ecosystem processes as wildfires burn larger areas or burn more frequently than the recent natural range of variability. The climatic drivers of wildfire behavior may change in strength but these effects are not likely to be uniform across space and between different vegetation types. Increased understanding of how weather and climate influence patterns of burn area and frequency across vegetation types may assist in better predicting and managing future wildfire regimes. We examined a dataset of all 1469 wildfires ≥40 ha from 1984 – 2021 in Utah, USA and used antecedent daily weather data …

Electrochemical Sensors For In Situ Monitoring Of Reactive Species During Cold Atmospheric Plasma-Based Therapies, Jonathan Thomas, Suneel Kumar, Gagana Karkada, Julia Sutter, Kristina Pattison, Jason Rainone, Dhruv Patel, Shashank Madhavan, Fred Krebs, Francois Berthiaume, Vandana Miller, Katharina Stapelmann

Kimmel Cancer Center Faculty Papers

Cold atmospheric pressure plasma (CAP) is emerging as a clinically relevant therapy for dermatological conditions such as actinic keratosis, warts, and chronic wounds. However, these therapies lack strategies to monitor CAP delivery in situ and to ensure delivery of an effective CAP dose without unwanted toxicity. CAP acts as a therapeutic agent in these biomedical applications primarily (but not solely) through reactive oxygen and nitrogen species (RONS) generated at transiently high local concentrations. Here we demonstrate the use of bio-electrochemical sensors capable of real-time measurements of key CAP RONS: hydrogen peroxide and oxidation-reduction-potential (ORP). In in vitro scratch assays and …

Tree species preference is an understudied yet crucial component of sustainable forest management, as unsustainable harvesting can lead to non-random loss of functional traits. We examine wood resource preference across five regions of Madagascar's biodiverse eastern humid forests. We asked forest users in 19 men's and 19 women's focus groups to list their preferred tree species for common short- (charcoal, firewood) and long-term (house construction, furniture, tools) uses. We then measured functional traits of 260 preferred and common tree species: height, DBH, bark thickness, specific leaf area, wood specific gravity, and seed dispersal syndrome in the surrounding landscape. Using household …

I Can’T Believe It’S Not Social: Investigating The Relationship Between Loneliness, Parasocial Relationships, And Potential Moderators, Hannah I. Suozzi

Master's Theses

Increased loneliness trends coincide with increased media use. Media is turned to as a source of comfort and distraction from the real world. There is cause to believe that people also use media as a way to form parasocial relationships (PSRs), one-sided relationships audiences form with media figures (i.e., celebrities, influencers, and fictional characters). The connection between loneliness and PSR is thought to be moderated by social vulnerability, particularly the need to belong (NTB) and ethnicity. The medium from which PSRs originate lacks empirical study. To address the limitations, this study analyzed data collected from San Jose State University students …

Conceptions Of Indigenous Child Development: Perspective Of Families And Health Professionals, Francisca Marquez-Doren, Camila Lucchini-Raies, Marcela Gonzalez-Aguero, Angelica Farías-Cancino

Biennial Convention (CONV)

Introduction. The factors that deprive children of their rights are well known, and one of them is their belonging to indigenous peoples. Indigenous children in their early childhood are exposed to greater social inequalities, as they are born and develop in more unfavorable living conditions (Alarcón Muñoz et al., 2021; Pyerín & Weinstein, 2015). The percentage of poverty, deficits in education, social security and work is higher in indigenous early childhood (Pyerín & Weinstein, 2015). In Chile, children belonging to indigenous peoples account for around 14% of the population between 0 and 9 years of age, with the Mapuche, Aymara …

Military Ai And The Specter Of The Limitless War, Yuval Shany, Yahli Shereshevsky

International Law Studies

Legal and extra-legal factors related to the development of international humanitarian law (IHL) support the exercise of strategic restraint during armed conflicts. We claim, however, that technological developments in the area of military artificial intelligence (AI) fundamentally do away with many of the technological constraints that limited the capacity of militaries to fully utilize the “license to kill” afforded to them by IHL. Such a violence-enhancing effect can become even more dramatic in cases where other restraining factors are less effective. The upshot of our analysis is that the implicit assumption that IHL would be applied in a context of …
