It explores the limitations of common black box IDS and the complexities of explainability methods, leading to the fundamental question of trusting explanations generated by black box …

Advancing Air Filtration Analysis: A Comprehensive Approach To Particle Loading Models, Gentry Nathaniel Berry

Theses and Dissertations

Fibrous air filters are commonly used to capture airborne particles due to their potential for a relatively high capture efficiency and low airflow resistance. Their performance characteristics make them ideal candidates in many instances, spanning a wide range from residential to sensitive industrial applications. However, as more particles are captured, the performance of the filter will evolve. This evolution of performance typically manifests as a higher capture efficiency and higher airflow resistance resulting from the additional particulate deposits. The prediction of fibrous filter performance has been the focus of research for many decades, resulting in numerous analytical, numerical, and empirical …

Design, Development, And Validation Of A Perfusion-Compression Bioreactor To Study Osteogenesis In Bone Explants, Alexis Victoria Graham

Theses and Dissertations

The current gold standard treatment for bone defects is autologous cancellous bone graft, which involves increased surgery time and donor site morbidity, and limited supply of bone and cells for regeneration. Bioreactors may aid in the generation of mechanically conditioned bone grafts with more cells compared to traditional grafts. However, the specific parameters of fluid flow and mechanical loading which contribute to osteogenesis and cell viability in bioreactors are not fully characterized. Here, a perfusion-compression bioreactor system was developed to study osteogenesis in porcine trabecular bone explants. Loading accuracy was over 88% across six bioreactors at a 0.1 s-1 strain …

Phenotyping Cotton Compactness Using Machine Learning And Uas Multispectral Imagery, Joshua Carl Waldbieser

Theses and Dissertations

Breeding compact cotton plants is desirable for many reasons, but current research for this is restricted by manual data collection. Using unmanned aircraft system imagery shows potential for high-throughput automation of this process. Using multispectral orthomosaics and ground truth measurements, I developed supervised models with a wide range of hyperparameters to predict three compactness traits. Extreme gradient boosting using a feature matrix as input was able to predict the height-related metric with R2=0.829 and RMSE=0.331. The breadth metrics require higher-detailed data and more complex models to predict accurately.

Stress-Related Biosocial Mechanisms Of Discrimination And African American Health Inequities, Bridget J. Goosby, Jacob E. Cheadle, Colter Mitchell

Department of Sociology: Faculty Publications

This review describes stress-related biological mechanisms linking interpersonal racism to life course health trajectories among African Americans. Interpersonal racism, a form of social exclusion enacted via discrimination, remains a salient issue in the lives of African Americans, and it triggers a cascade of biological processes originating as perceived social exclusion and registering as social pain. Exposure to discrimination increases sympathetic nervous system activation and upregulates the HPA axis, increasing physiological wear and tear and elevating the risks of cardiometabolic conditions. Consequently, discrimination is associated with morbidities including low birth weight, hypertension, abdominal obesity, and cardiovascular disease. Biological measures can provide …

Communication Sciences And Disorders Students’ Awareness Of The Deaf Community, Deaf Culture, And American Sign Language, Kenna Reece

Undergraduate Honors Theses

For medical professionals in any field, it is vastly important to be culturally sensitive to one’s clients and patients. The history of audiologists, speech-language pathologists (SLPs), and the Deaf community is complicated and painful, causing distrust towards medical professionals among many Deaf people. There is little research looking into the area of awareness of Deaf culture among practicing audiologists and SLPs. Select studies into this area, that focused on other medical professionals, have shown that many clinicians have had experience with American Sign Language (ASL) and the Deaf community, but there is still a lack of important knowledge and discomfort …

With the San Antonio Statement from 2010 banning halogenated FRs, there has been a push in research towards safer and better alternatives. The synthesis of a novel disulfide triazole organophosphate fire retardant (DSTP) would aid in NSF EPSCoR’s HDRFS research as a greener and better alternative. Therefore, our research aimed to i) develop a novel FR that harnesses the synergistic effects of phosphate-, disulfide-, and triazole-functionality that can be applied to …

Reminders Of Reconsolidation: Prediction Error Vs. Spatial Context, Mateo Marquez, Jessica Nguyen, Augustine Alvarado

Undergraduate Research Symposium Posters

Reconsolidation is the process whereby reactivating a consolidated memory can bring it into a labile state where it can be strengthened, weakened, or updated. Spatial context and prediction error (PE) are two ways that memories can be reactivated. Spatial context refers to being in the same-environmental setting during encoding and retrieval, whereas PE refers to the mismatch between expected and observed events. Both methods have successfully reactivated consolidated memories. However, it is unclear whether reconsolidation is affected by PE when it isolated in different spaces.

The Role Of Prediction Error In Episodic Memory, Natalie Chisam, Natalie Hsiao

A Timeline Of Klinefelter’S Syndrome, Xxy, Emma Chevalier, Tyler Venegas, Mary Salibi

Undergraduate Research Symposium Posters

Klinefelter Syndrome (KS) is a non-mendelian chromosomal disorder consisting of supernumerary X chromosomes in males, 80% of which manifest as the 47,XXY karyotype. The resulting gene dosage abnormalities affect both cognitive and physical development, with variable expressivity. The disease was first described by Harry Klinefelter in 1942 and was thought to be an endocrine disorder until the late 1950s, when karyotyping of affected individuals revealed an extra X chromosome.

(It is the most common sex chromosome aneuploidy (1:500 males) and the most common cause of azoospermia. The phenotype for KS is highly contested due to its extremely variable expressivity and …

Undergraduate Research Symposium Posters

In 2020, the National Highway Traffic Safety Administration (NHTSA) reported that Nevada was the 10th highest ranking in pedestrian fatality rates. According to a report by Zero Fatalities, in 2021, there were 84 pedestrian deaths. Underserved communities, the elderly, and low income individuals are more likely to use walking, biking, or public transportation as a primary means of transportation due to vehicle expenses. Older adults, racial/ethnic minorities and those with lower socioeconomic statuses (SES) may bear a disproportionate burden of auto-pedestrian crashes.

A Genetic Screen For Metabolic Modulators In Drosophila Melanogaster, Victoria Campos, Logan Kazimer, Brandon Polimeni, Katelyn Niswonger, Matthew Meiselman

Undergraduate Research Symposium Posters

When environments become unfavorable, to preserve energy, animals will attenuate reproduction and limit growth. This evolutionary strategy requires perceiving and assessing a complex environment, a long-standing role of the nervous system. However, the nervous system’s control over endocrine states remains a monumental challenge. Here, we propose to exploit the genetic accessibility and cellular resolution readily found in Drosophila melanogaster, to fully explore how the brain controls metabolic and reproductive states. This project relies on the Meiselman Lab’s established unbiased neural activation screen, which located new neural circuits that participate in metabolic control. The project proposes the use of the split …

Listener’S Judgement Of Tempo Is Influenced By Dance Speed, Carolina A. Herrera, Ryan K. Perez, Jared W. Leslie, Erin E. Hannon

Undergraduate Research Symposium Posters

The tempo of a musical composition is typically denoted by the number of beats per minute (BPM). Nevertheless, perception of tempo is inherently subjective, and it can be shaped by the listener's familiarity with both musical and dance elements [1, 2, 3, 4]. Even when songs have the same BPM, the perceived speed of the songs can differ based on the specific dance form and cultural context [1, 4]

Perceptual Learning Of Infants Across Domains, Melanie Garcia, Carolina A. Herrera, Ryan K. Perez, Rodica R. Constantine, Erin E. Hannon

Undergraduate Research Symposium Posters

Infancy is a unique developmental period in which there is rapid attunement of perceptual systems to specific environmental properties. Perceptual narrowing: By the end of the first year, infants become adept processors and develop expertise of familiar socially meaningful domains such as faces, language, and music leading to subsequent social and cognitive abilities. The mechanisms driving these perceptual changes remain debated, with contrasting accounts proposing experience-dependent or domain-general influences. Objective: This research aims to investigate whether perceptual narrowing in early development is primarily driven by domain-specific experiences or by domain-general factors such as brain maturation and information processing.
