Preventing And Managing Equine Gastric Ulcer Syndrome, Kylie Bell, Karl Hoopes

All Current Publications

Current industry trends regarding equine management practices largely contribute to the development of equine gastric ulcer syndrome (EGUS). Research on effective medical management exists; however, we lack studies on the efficacy of equine-welfare-minded solutions. This fact sheet reviews current literature, including diagnosing, treating, and preventing EGUS. It also provides a general overview of the natural equine, promoting a greater understanding of the connection between strategies to prevent and manage EGUS.

Habits And Externalities, Arthur J. Caplan

Applied Economics Faculty Publications

We develop a conceptual model characterizing two types of individuals: one myopic and the other hyperopic. A myopic individual ignores his private contributions to both a social and private negative externality, as well as the effect that his accumulation of stuff (i.e., the stock of consumption goods) has on his habit parameter. A hyperopic individual internalizes both externalities as well as his habit-formation effect. We find that the hyperopic individual consumes a greater amount of a clean good and a lesser amount of a dirty good, with the magnitude of the latter difference being greater than the magnitude of the …

Thought-Shape Fusion In Residential Eating Disorder Treatment: Cognitive Defusion As A Mediator Between Thought-Action Fusion And Treatment Outcome, Mercedes G. Woolley, Sarah E. Schwartz, Francesca M. Knudsen, Tera Lensegrav-Benson, Benita Quakenbush-Roberts, Michael P. Twohig

Psychology Faculty Publications

An understudied cognitive bias within eating disorder (ED) psychopathology is Thought-Shape Fusion (TSF), which involves irrational beliefs about the likelihood and moral implications of feared outcomes within the context of ED treatment, with little known about potential process of change to address TSF and ultimately promote ED recovery. We propose cognitive defusion as a process of change, a metacognitive process that emphasizes observing thoughts objectively rather than appraising thoughts as absolute truth. We explored whether cognitive defusion, that is, reductions in body image-related cognitive fusion, mediated the relationship between trait-level TSF and treatment outcomes in a transdiagnostic ED sample of …

Forest Defoliation By And Invasive Outbreak Insect: Catastrophic Consequences For A Charismatic Mega Moth, Richard L. Lindroth, Mark R. Zierden, Clay J. Morrow, Patricia C. Fernandez

Aspen Bibliography

Earth is now experiencing declines in insect abundance and diversity unparalleled in human history. The drivers underlying those declines are many, complex, and incompletely known. Here, using a natural experiment, we report the first test of the hypothesis that forest defoliation by an invasive outbreak insect compromises the fitness of a native insect via damage-induced increases in toxicity of the forest canopy. We demonstrate that defoliation by the invasive spongy moth (Lymantria dispar) elicits an average 8.4-fold increase in foliar defense expression among aspen (Populus tremuloides) genotypes. In turn, elevated defense dramatically reduces survivorship, feeding, and …

Signatures Of Fluid-Rock Interactions In Shallow Parts Of The San Andreas And San Gabriel Faults, Southern California, James P. Evans, Kaitlyn Crouch, Caroline Studnicky, Sharon Bone, Nicholas Edwards, Samuel M. Webb

Geosciences Faculty Publications

We examine deformed crystalline bedrock in the upper parts of the active San Andreas and ancient San Gabriel Faults, southern California, to 1) determine the nature and origin of micro-scale composition and geochemistry of fault-related rocks, 2) constrain the extent of fluid-rock interactions, and 3) determine the interactions between alteration, mineralization, and deformation. We used drill cores from a 470 m long inclined borehole through the steep-dipping San Gabriel Fault and from seven inclined northeast-plunging boreholes across the San Andreas Fault zone to 150 m deep to show that narrow fault cores 10 cm to 5 m wide lie within …

This fact sheet provides information on how Utah’s government and other entities are working to expand modes of transport that minimize harm to communities and the environment.

Electro-Optic Time Transfer With Femtosecond Stability, Joshua Olson, Robert Rockmore, Nathan D. Lemke, Sean Krzyzewski, Brian Kasch

Space Dynamics Laboratory Publications

Optical two-way time and frequency transfer is an enabling technology that has applications ranging from fundamental investigations of relativity to the operation of global navigation satellite systems. While fiber frequency combs have demonstrated the most stable optical links, they are not ideal for applications that require very low SWaP-C. Here, we demonstrate two-way time and frequency transfer using electro-optic combs that have a direct path to full chip-scale integration. This two-way electro-optic time and frequency transfer system demonstrated instabilities as low as 15 fs at 1 s of averaging time. These results show a pathway to highly stable, agile and …

Malivhu: A Comprehensive Bioinformatics Resource For Filtering Sars And Mers Virus Proteins By Their Classification, Family And Species, And Prediction Of Their Interactions Against Human Proteins, David Guevara-Barrientos, Rakesh Kaundal

Computer Science Student Research

COVID 19 pandemic is still ongoing, having taken more than 6 million human lives with it, and it seems that the world will have to learn how to live with the virus around. In consequence, there is a need to develop different treatments against it, not only with vaccines, but also new medicines. To do this, human-virus protein-protein interactions (PPIs) play a key part in drug-target discovery, but finding them experimentally can be either costly or sometimes unreliable. Therefore, computational methods arose as a powerful alternative to predict these interactions, reducing costs and helping researchers confirm only certain interactions instead …

Simulating The Long-Term Response Of Forest Succession To Climate Change In The Boreal Forest Of Northern Ontario, Canada, Guy R. Larocque, F. Wayne Bell, Eric B. Searle, Stephen J. Mayor, Thomas Schiks, Parvin Kalantari

Aspen Bibliography

The effect of climate change on forest dynamics is likely to increase in importance in the forthcoming decades. For this reason, it is essential to predict the extent to which changes in temperature, precipitation, and atmospheric CO₂ might affect the development of forest ecosystems and successional pathways. The gap model ZELIG-CFS was used to simulate the potential long-term effects of climate change on species-specific annual change in mean basal area and stand density under two scenarios of representative concentration pathways (RCP), 4.5 and 8.5, for the boreal forest region of Ontario, Canada, where mean temperature, precipitation, and atmospheric CO …

Managing Equine Metabolic Syndrome, Abigail Meldrum, Karl Hoopes

All Current Publications

Equine metabolic syndrome (EMS) is a relatively new disease that we are still learning about. There are many things to investigate when dealing with a new disease: causes, predispositions, symptoms, secondary issues, treatments, and prevention. Because changing the animal's feed regimen is currently the most effective and well-known way to manage EMS, this fact sheet focuses primarily on how diet can impact affected horses. As a newer syndrome, it is vital to learn as much as possible about it to understand, treat, and prevent this disease.

Assimilating Satellite-Derived Snow Cover And Albedo Data To Improve 3-D Weather And Photochemical Models, Colleen Jones, Huy Tran, Trang Tran, Seth Lyman

Chemistry and Biochemistry Faculty Publications

During wintertime temperature inversion episodes, ozone in the Uinta Basin sometimes exceeds the standard of 70 ppb set by the US Environmental Protection Agency. Since ozone formation depends on sunlight, and less sunlight is available during winter, wintertime ozone can only form if snow cover and albedo are high. Researchers have encountered difficulties replicating high albedo values in 3-D weather and photochemical transport model simulations for winter episodes. In this study, a process to assimilate MODIS satellite data into WRF and CAMx models was developed, streamlined, and tested to demonstrate the impacts of data assimilation on the models’ performance. Improvements …

Cognitive Reappraisal: The Bridge Between Cognitive Load And Emotion, Rebecca Brockbank, David F. Feldon

Instructional Technology and Learning Sciences Faculty Publications

Within this integrative review, cognitive load theory (CLT) is asserted as a powerful framework for conceptualizing human cognitive processes within learning. The relationship between cognition and emotion is then examined and further integrated within the scope of CLT. Emotion regulation strategies are discussed and adaptive strategies are proposed as being of particular relevance to broadening the theoretical and practical impacts of CLT. Central to the argument of this review is the use of cognitive reappraisal as a potential mitigator of cognitive load. Cognitive reappraisal involves reframing or reassessing understandings or beliefs that underlie an emotional response, which may mitigate cognitive …

Balancing Results From Ai-Based Geostatistics Versus Fuzzy Inference By Game Theory Bargaining To Improve A Groundwater Monitoring Network, Masoumeh Hashemi, Richard C. Peralta, Matt Yost

Plants, Soils and Climate Student Research

An artificial intelligence-based geostatistical optimization algorithm was developed to upgrade a test Iranian aquifer's existing groundwater monitoring network. For that aquifer, a preliminary study revealed that a Multi-Layer Perceptron Artificial Neural Network (MLP-ANN) more accurately determined temporally average water table elevations than geostatistical kriging, spline, and inverse distance weighting. Because kriging is usually used in that area for water table estimation, the developed algorithm used MLP-ANN to guide kriging, and Genetic Algorithm (GA) to determine locations for new monitoring well location(s). For possible annual fiscal budgets allowing 1-12 new wells, 12 sets of optimal new well locations are reported. Each …

Body Length Determines Flow Refuging For Rainbow Trout (Oncorhynchus Mykiss) Behind Wing Dams, Terry R. Dial, Laura A. Collins, James C. Liao, Bret W. Tobalske

Environment and Society Faculty Publications

Complex hydrodynamics abound in natural streams, yet the selective pressures these impose upon different size classes of fish are not well understood. Attached vortices are produced by relatively large objects that block freestream flow, which fish routinely utilize for flow refuging. To test how flow refuging and the potential harvesting of energy (as seen in Kármán gaiting) varies across size classes in rainbow trout (Oncorhynchus mykiss; fingerling, 8 cm; parr, 14 cm; adult, 21 cm; n = 4 per size class), we used a water flume (4,100 L; freestream flow at 65 cm s^-1) and created …

Neuromorphic Star Tracking Using Monte Carlo Localization, Connor Gisburne, Alex Warren, Steven Allen, Michael Bantel, Justin James

Small Satellite Conference

Accurate attitude determination ensures precise payload sensor alignment and optimal solar panel positioning, enhancing data collection and power efficiency while ensuring stable orbit maintenance. The most accurate method of attitude determination is star tracking. Star trackers collect an image of a star field and utilize a catalog of known star positions to calculate the orientation of the system relative to the stars. The errors present in this method of attitude determination tend to be on the order of ten arcseconds or less. Using traditional collection techniques, attitude estimates can be provided at update rates of 1 to 10 Hz and …

Equatorial Low Earth Orbit (Eleo): An Orbital Incubator And Nursery, Siegfried Janson

Small Satellite Conference

Recent research has shown that Equatorial Low Earth Orbit (ELEO) below 500 km has an exceptionally low space radiation environment that is ideal for long-term space settlements. The pressure vessel itself provides enough radiation shielding to enable decades of on-orbit habitation for an individual without exceeding radiation safety limits. My calculations using SPENVIS show that a minimum radiation "Incubator" region exists between 24° inclination at 350 km altitude, which drops linearly with increasing altitude to 0° inclination at 550 km altitude. Silicon-based spacecraft electronics inside a 1-mm thick aluminum hull would have a trapped particle dose rate ~4 orders-of-magnitude lower …
