Confirmatory Factor Analysis Of The Causal Illness Attribution Scale In Chinese Patients With Multiple Somatic Symptoms, Ling Zhang, Jeanine Schwarz, Maria Kleinstäuber, Kurt Fritzsche, Wiebke Hannig, Jing Wei, Jianzhong Yang, Lan Zhang

Psychology Faculty Publications

Causal illness attributions influence how individuals cope with somatic symptoms and illnesses. Dimensions of causal symptom attributions have been examined in Western cultures with the subscale ‘causes’ of the revised Illness Perception Questionnaire (IPQ-R). Some previous studies have identified a stronger somatic attribution style in Asian patients. In this study it was examined if the factorial structure of causal attributions identified in Western populations can be identified in a large Chinese sample of patients presenting with somatic symptoms. We recruited 665 patients aged at least 18 who were visiting the hospital for reasons of treatment from departments of traditional Chinese …

Public Safety And Unauthorized Extreme Activities At Spillways, Steven L. Barfuss, Brian M. Crookston

International Symposium on Hydraulic Structures

One very important purpose for reservoirs is the recreational opportunities they provide to the general public. Unfortunately, some people engage in highly dangerous or extreme activities at dams and spillways that occasionally result in severe injury or death. In addition, some individuals purposely choose to ignore signage and safety fencing in order to access spillways and other hydraulic structures at the dam. Social media has become a means for advertising extreme activities that often occur on the physical structures at dams and spillways like surfing, wakeboarding, sledding, snowmobiling, skating, biking, diving, sliding, climbing, skateboarding, kayaking, wading and jumping. This only …

Making Strides: State Of The Practice Of Pedestrian Forecasting In Regional Travel Models, Patrick A. Singleton, Joseph C. Totten, Jaime P. Orrego-Oñate, Robert J. Schneider, Kelly J. Clifton

Civil and Environmental Engineering Faculty Publications

Much has changed in the 30 years since non-motorized modes were first included in regional travel demand models. As interest in understanding behavioral influences on walking and policies requiring estimates of walking activity increase, it is important to consider how pedestrian travel is modeled at a regional level. This paper evaluates the state of the practice of modeling walk trips among the largest 48 metropolitan planning organizations (MPOs) and assesses changes made over the last 5 years. By reviewing model documentation and responses to a survey of MPO modelers, this paper summarizes current practices, describes six pedestrian modeling frameworks, and …

Organic Compound Emissions From A Landfarm Used For Oil And Gas Solid Waste Disposal, Seth N. Lyman, Marc L. Mansfield

Chemistry and Biochemistry Faculty Publications

Solid or sludgy hydrocarbon waste is a byproduct of oil and gas exploration and production. One commonly-used method of disposing of this waste is landfarming. Landfarming involves spreading hydrocarbon waste on soils, tilling it into the soil, and allowing it to biodegrade. We used a dynamic flux chamber to measure fluxes of methane, a suite of 54 non-methane hydrocarbons, and light alcohols from an active and a remediated landfarm in eastern Utah, U.S.A. Fluxes from the remediated landfarm were not different from a PTFE sheet or from undisturbed soils in the region. Fluxes of methane, total non-methane hydrocarbons, and alcohols …

A 10b Sar Adc With An Ultra-Low Power Supply, Alexander Petrie

Utah Space Grant Consortium

A 0.2V 10-bit 5 kS/s Successive Approximation Register ADC design is presented. This design achieves a very low power consumption due to the ultra-low power supply voltage used. Different aspects in the ADC design are optimized for 0.2V and modified to meet the speed requirements for the ADC. Preliminary Cadence simulations show a 4nW total power consumption with a peak SNDR of 57 dB and a FOM of 1.3 fJ/conversion-step.

Using Combined Microgravity And Radiation To Simulate Skeletal Muscle Damage In Space, Lori Caldwell

Utah Space Grant Consortium

Muscular atrophy, defined as the loss of muscle tissue, is a serious issue for immobilized patients on Earth and in human spaceflight, where microgravity prevents normal muscle loading. Developing countermeasures for atrophy in spaceflight will require extensive screening of pharmaceuticals for efficacy, safety, contraindications, and dosage schedule. Due to the cost of spaceflight and limited crew time aboard the International Space Station, high throughput screening of pharmaceuticals under real microgravity conditions is not feasible. While traditional ground-based atrophy studies using the rodent hind-limb unloading model are effective at inducing physiological changes similar to spaceflight, they are not suited for first …

Genome Polymorphism Detection Through Relaxed De Bruijn Graph Construction, Stanley Fujimoto

Utah Space Grant Consortium

Comparing genomes to identify polymorphisms is a difficult task, especially beyond single nucleotide polymorphisms. Polymorphism detection is important in disease association studies as well as in phylogenetic tree reconstruction. We present a method for identifying polymorphisms in genomes by using a modified version de Bruijn graphs, data structures widely used in genome assembly from Next- Generation Sequencing. Using our method, we are able to identify polymorphisms that exist within a genome as well as well as see graph structures that form in the de Bruijn graph for particular types of polymorphisms (translocations, etc.)

Emergency Landing Of Small Unmanned Aerial Systems, Parker Lusk

Utah Space Grant Consortium

An algorithm for vision-based emergency landing of a multirotor is outlined. Using a recently developed real-time visual multiple target tracker, a potential fields-based obstacle avoidance algorithm is employed to find the “safest” part of a pre-determined landing site. A sliding mode controller for image-based visual servoing is designed that allows globally asymptotic tracking of a line of sight vector and the optical axis. The presented forced landing scheme allows for quick emergency landings to be performed in populated environments with moving ground obstacles.

A Model For Determining A Patient-Specific Oxyhemoglobin Dissociation Curve, Kyle Burk

Utah Space Grant Consortium

Introduction: The oxyhemoglobin dissociation curve describes the relationship between the partial pressure of oxygen and the percent of hemoglobin saturated with oxygen. This relationship is a sigmoidal shaped curve. The oxyhemoglobin dissociation curve varies from patient to patient. If patient variability could be determined patient specific oxygen flow rates could be delivered. We have developed a model for characterizing patient specific variations in SpO2. Our model predicts saturation by generating a patient-specific oxyhemoglobin dissociation curve. The purpose of this study was to determine the effectiveness of our patient-specific model. Methods: We Probed SpO2 level at various oxygen inhalation amounts to …

Improving Technologies In Anesthesia, Patrick Kolbay

Utah Space Grant Consortium

General anesthesia is well known to offer physicians access to a broad variety of invasive procedures otherwise deemed too risky. Anesthesia machines provides the means for anesthetizing patients safely in the hospital operating room. However, these devices are increasingly unable to meet the demands and needs outside of the hospital. Developing countries struggle to purchase and maintain these costly devices, leading to a 40-fold increase in anesthesia-related deaths compared to developed countries. Small-office practices in the United States experience significantly poorer anesthesia outcomes and increased legal claims versus their larger hospital counterparts, resulting in 60% more anesthesia-related deaths. Environmental impacts …

Characterization Of An N-Terminal Non-Core Domain Of Rag1 Gene Disrupted Syrian Hamster Model Generated By Crispr Cas9, Jinxin Miao, Baoling Ying, Rong Li, Ann E. Tollefson, Jacqueline F. Spencer, William S.M. Wold, Seok-Hwan Song, Il-Keun Kong, Karoly Toth, Yaohe Wang, Zhongde Wang

Animal, Dairy, and Veterinary Science Faculty Publications

The accumulating evidence demonstrates that Syrian hamsters have advantages as models for various diseases. To develop a Syrian hamster (Mesocricetus auratus) model of human immunodeficiency caused by RAG1 gene mutations, we employed the CRISPR/Cas9 system and introduced an 86-nucleotide frameshift deletion in the hamster RAG1 gene encoding part of the N-terminal non-core domain of RAG1. Histological and immunohistochemical analyses demonstrated that these hamsters (referred herein as RAG1-86nt hamsters) had atrophic spleen and thymus, and developed significantly less white pulp and were almost completely devoid of splenic lymphoid follicles. The RAG1-nt86 hamsters had barely detectable CD3+ and CD4+ T cells. The …

Non-Linear Analysis Of Visual-Motor Tracking Pre- And Post-Heading In Collegiate Female Soccer Athletes, Sonia Delbusso

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

Context: There has been minimal examination of the long-term effects of sub-concussive events, particularly related to non-linear aspects of motor performance. Examining the structure of performance, using nonlinear techniques, following sub-concussive events may lend insight into subtle, but significant changes in motor behavior.

Objective: This study examined the effect of performing a bout of headers on visual motor control in a group of female soccer athletes. We specifically examined the amount of error during visual-motor tracking (root mean squared error; RMSE), the regularity of the movement structure (sample entropy; SampEn), and the lag present between the target signal and the …

Comparison Of Vestibular Contribution During Stair Ascent, Stair Descent, And Treadmill Locomotion, Alexander Kern

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

Stair negotiation accounts for 16% of fall related traumatic spinal cord injuries and the vestibular system plays a crucial role in fall avoidance through its role in maintaining balance during human locomotion, but its role in stair negotiation is unclear. The aim of this study was to compare the vestibular contribution to a) stair negotiation versus locomotion and b) stair ascent to stair descent in healthy young participants. It was hypothesized that, with cadence held constant, vestibular influence would increase during stair negotiation when compared to locomotion. We also expected the vestibular influence to increase during stair descent vs. ascent. …

A Review Of Impact Testing Used For The Diagnosis Of Concussion And The Influence Of Language Of Test Administration, Carley Bishop

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

The Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) battery is a widely used tool for the diagnosis and treatment of concussions. The purpose of this review was to evaluate studies that account for patient language and language of test administration when conducting ImPACT. A total of 36 articles were reviewed. The 36 articles reviewed accounted for English speaking populations and five of the articles accounted for populations representing different languages. Five of the studies were test-retest reliability studies. The results indicated that ImPACT has acceptable test-retest reliability when used in English to monolingual English-speaking participants. However, the results demonstrated ImPACT …

Linking The Medical And Educational Home To Support Children With Autism Spectrum Disorder: Practice Recommendations, Jeffrey D. Shahidullah, Gazi Azad, Katherine R. Mezher, Maryellen Brunson Mcclain, Laura Lee Mcintyre

Psychology Faculty Publications

Children with autism spectrum disorder (ASD) present with complex medical problems that are often exacerbated by a range of other intellectual and psychiatric comorbidities. These children receive care for their physical and mental health from a range of providers within numerous child-serving systems, including their primary care clinic, school, and the home and community. Given the longitudinal nature in which care is provided for this chronic disorder, it is particularly necessary for services and providers to coordinate their care to ensure optimal efficiency and effectiveness. There are 2 primary venues that serve as a “home” for coordination of service provision …

Structural Characterization Of The P1+ Intermediate State Of The P-Cluster Of Nitrogenase, Stephen M. Keable, Oleg A. Zadvornyy, Lewis E. Johnson, Bojana Ginovska, Andrew J. Rasmussen, Karamatullah Danyal, Brian J. Eilers, Gregory A. Prussia, Axl X. Levan, Simone Raugei, Lance C. Seefeldt, John W. Peters

Chemistry and Biochemistry Faculty Publications

Nitrogenase is the enzyme that reduces atmospheric dinitrogen (N₂) to ammonia (NH₃) in biological systems. It catalyzes a series of single-electron transfers from the donor iron protein (Fe protein) to the molybdenum–iron protein (MoFe protein) that contains the iron–molybdenum cofactor (FeMo-co) sites where N₂ is reduced to NH₃. The P-cluster in the MoFe protein functions in nitrogenase catalysis as an intermediate electron carrier between the external electron donor, the Fe protein, and the FeMo-co sites of the MoFe protein. Previous work has revealed that the P-cluster undergoes redox-dependent structural changes and that the …

Structure Of Frequency-Interacting Rna Helicase From Neurospora Crassa Reveals High Flexibility In A Domain Critical For Circadian Rhythm And Rna Surveillance, Yalemi Morales, Keith J. Olsen, Jacqueline M. Bulcher, Sean J. Johnson

Chemistry and Biochemistry Faculty Publications

The FRH (frequency-interacting RNA helicase) protein is the Neurospora crassa homolog of yeast Mtr4, an essential RNA helicase that plays a central role in RNA metabolism as an activator of the nuclear RNA exosome. FRH is also a required component of the circadian clock, mediating protein interactions that result in the rhythmic repression of gene expression. Here we show that FRH unwinds RNA substrates in vitro with a kinetic profile similar to Mtr4, indicating that while FRH has acquired additional functionality, its core helicase function remains intact. In contrast with the earlier FRH structures, a new crystal form of FRH …

Wyoming's High Desert: Aspen habitat presents challenges

Kevin Spence

The high elevation desert of southwest Wyoming occurs between 6,040 ft. and 9,550 ft. Isolated “high points” in the area are dryland oases supporting high aquatic and terrestrial wildlife species richness, as vegetative diversity provides essential life stage habitat needs for numerous species. Although aspen makes up the smallest percentage of all vegetation types on this landscape, I consider aspen stands and their associate understories the most ecologically important in this ecosystem. Just a few benefits these aspen stands provide include: solid dam building material for beaver pond complexes providing riparian …

Does Talker Familiarity Or Time Of Testing Facilitate Sentence Recognition When Listening In Noise?, Madison S. Buntrock

Undergraduate Honors Capstone Projects

At the most elementary level, the speech signal is comprised of two parts: linguistic information and indexical information. The linguistic information is the phonetic information of the signal and indexical information is speaker specific and is the paralinguistic information of the signal. Part of this indexical information is talker specific characteristics; which have been shown to help people understand speech. The talker specific characteristic we looked at was talker familiarity. Talker familiarity has been shown to help babies segment speech and adults listen in noise and recall stories. We looked at talker familiarity to see if it would benefit typically …

Maternal Vitamin D Deficiency And Early Childhood Health Outcomes Including Autism Development, Kelsey L. Girardelli

Undergraduate Honors Capstone Projects

Many studies have shown that vitamin D deficiency during pregnancy is associated with a variety of adverse maternal and pediatric outcomes. Disease outcomes that have been observed in pregnant women who are vitamin D deficient include increased risk of C-section, preeclampsia, bacterial vaginosis, and gestational diabetes. In children born to deficient mothers, increased rates of childhood asthma, type 1 diabetes, low birthweight, and autism spectrum disorder (ASD) have been observed. Although there is much evidence to support these correlations, much is yet to be understood regarding the etiology of these outcomes. This paper specifically examines the relationships between risk factors …
