Enhanced Neural Network-Based Cell Identification Through Vectorized Phase Information In Reconstructed Holograms, Tyler Daynes, Jeremy Tait, Rylee Russell, Harrison Welch, Vern Hart

Utah Space Grant Consortium

Survival rates for most cancers have increased steadily over the past few decades as new technologies have led to better treatment outcomes. However, this process often relies heavily on the detection of cancer in its earliest stages, before symptoms occur or a tumor is visible in a CT or MR image. This is particularly true for diseases such as pancreatic cancer that exhibit almost no symptoms until very late stages and have extremely low survival rates as a result. Even some commonly treatable diseases, such as breast cancer, become far more problematic in later stages. As such, any efforts to …

Urine Oxygen Partial Pressure Monitoring To Assess Acute Kidney Injury Risk, Lars Lofgren, Kai Kück, Natalie Silverton

Utah Space Grant Consortium

Acute kidney injury (AKI) is a common complication associated with cardiac surgery. AKI is associated with increased hospital costs, hospital length of stay (LOS), and mortality risk. The KDIGO criteria are the most common diagnostic criteria and are based on changes in serum creatinine and decreased urine output. While useful for estimating renal function, serum creatinine and urine output are not renal specific, can be influenced by factors other than kidney injury and lead to delayed AKI diagnosis which precludes injury prevention. To overcome these limitations, researchers have primarily focused on chemical biomarkers. The use of these tests is limited …

Investigating The Effects Of Radiation And Microgravity On Human Brain Organoids, Bailey Mcfarland, Chen Cheng, Yu Huang

Utah Space Grant Consortium

The brain is arguably the most important and complex component of any crewed mission. New technological developments must be made to gauge the damage of space to the brain, especially in complex and long-term missions. While it is understood that microgravity and radiation cause changes in the brain of astronauts, the nature and effects of these changes are largely unknown. To aid in elucidating these effects, we conducted experiments using a rotary cell culture system (RCCS) and are working actively with NASA to implement a chronic low-dose gamma radiation system. Initial trends in the effects of microgravity on brain organoids …

Making The Old New: The Recontextualization And Traditionalization Of Tree Spirits In Video Games, Alexandria Ziegler

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Folklorists study the active rituals between humans and deities, as well as the inactive participation between them in narrative. However, they do not study the active participation that comes in the form of video games between them, though with shifts in society, this new way of engaging through digital forms is widespread and accessible. In my research, I studied Russian and Japanese tree spirits in a variety of video games to understand this new form of engagement with ancient deities. These video games are Okami, The Legend of Zelda: Breath of the Wild, Black Book, and The Witcher 3: The …

Religious Sexual Minorities, Belongingness, And Suicide Risk: Does It Matter Where Belongingness Comes From?, Samuel J. Skidmore, G. Tyler Lefevor, Rachel M. Golightly, Eric R. Larsen

Psychology Faculty Publications

Sexual minorities (SMs) experience a unique set of stressors as a result of their minority status that can lead to adverse mental health outcomes, including increased suicidal ideation (SI). A sense of belongingness—particularly in sexual minority communities—has been shown to buffer these outcomes. It is less clear, however, how belongingness in communities that hold heteronormative values may relate to SI. The present study fills this gap through an analysis of data from 602 SM members of the Church of Jesus Christ of Latter-day Saints (CJCLDS; “Mormon” church). We examine how minority stressors and religiousness are related to SI for SMs …

Wolf-elk-aspen interactions: Trophic cascade or trickle?

Elaine Brice

Dan MacNulty

As one of the world’s first National Parks, Yellowstone is renowned for a dynamic landscape that is home to many charismatic species. As one of the few deciduous trees in the Park, aspen is a valuable member of the ecosystem. A century of decline is mostly attributed to elk herbivory of aspen recruitment, while climatic factors are often regarded as unimportant.

Oystershell Scale: An Invasive Threat To Aspen Conservation, Amanda M. Grady, Connor D. Crouch, Nicholas P. Wilhelmi, Richard W. Hofstetter, Kristen M. Waring

Aspen Bibliography

Aspen decline is an acute and chronic problem in Arizona, where high levels of overstory mortality and a lack of recruitment continue to be observed. Oystershell scale (Lepidosaphes ulmi; OSS), an invasive sapsucking insect, has recently become widespread in native aspen stands in the southwestern U.S., further contributing to aspen mortality. Damage is severe in lower elevation stands and within ungulate exclosures created to conserve aspen. Young recruiting aspen that are rare on the landscape incur high levels of OSS-caused mortality when infested (Fig. 1). OSS has only recently become a pest of concern in the Southwest and …

Evaluating Short Term Effects Of Opportunity Zone Designation, Sarah M. Bennett

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Tax Cuts and Jobs Act of 2017 included a substantial economic development effort known as Opportunity Zones. These Zones cover 12% of the census tracts in the United States and are estimated to cost $1.6 billion in lost capital gains tax revenue. Our paper seeks to find whether this program has had an impact four years after going into effect, using an econometric analysis on changes in housing prices.

Minority Stress: A Model For Understanding Sexual Minority Adolescents’ Mental Health, Sean N. Weeks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Taken together, the three papers included in this dissertation offer an investigation of sexual minority adolescents’ stress as a predictor of adverse mental health outcomes (Paper 1), as being influenced by school and home climates (Paper 2), and as a measurable model for stress across levels (Paper 3). Results from this series of studies generally support theory and findings from other studies in that minority stress was found to be a meaningful predictor of mental health in sexual minority youth and that school and home climates were found to be important for understanding sexual minority youth wellbeing. However, the current …

Standardization Of A Protocol To Propagate Gateway Vectors, Kayla Suisse

Undergraduate Honors Capstone Projects

Cloning is an important technique in functional genomics, particularly genetics and molecular biology. Cloned genes can be used to facilitate protein expression; this is an essential step in understanding gene function. In traditional cloning, the gene of interest is amplified and tagged with a restriction enzyme sequence and ligated to the digested open vector. However, the GATEWAY™ Cloning Technology provides a speedy and more efficient route to insert the gene of interest in the desired vector, known as Destination vectors or Expression vectors, using site-specific recombination sites and recombinase enzymes.¹ Once DNA segments from the gene of interest are …

Bridging The Divide Between Upper And Lower Classmen: Resources For Mentors And Freshmen In The Choral Education Program, Tanner Hancock Pruett

Undergraduate Honors Capstone Projects

The recent decline in student retention in the choral education program at Utah State University should be cause for concern. Students who are excited and passionate about choir are leaving choral education and/or dropping out of college entirely. However, research into college retention rates and the experiences of choral education students at USU has helped explain this decline in student retention.

My review of research about college retention rates indicates that some of the biggest reasons that students drop out of college are academic difficulty, interpersonal difficulties, and mental health. It also indicates students with a strong sense of support …

Language Revitalization: Strategies To Reverse Language Shift, Jessica Jamiel Martin
