Ueb Parallel: Distributed Snow Accumulation And Melt Modeling Using Parallel Computing, Tseganeh Z. Gichamo, David G. Tarboton

Publications

The Utah Energy Balance (UEB) model supports gridded simulation of snow processes over a watershed. To enhance computational efficiency, we developed two parallel versions of the model, one using the Message Passing Interface (MPI) and the other using NVIDIA's CUDA code on Graphics Processing Unit (GPU). Evaluation of the speed-up and efficiency of the MPI version shows that the effect of input/output (IO) operations on the parallel model performance increases as the number of processor cores increases. As a result, although the computation kernel scales well with the number of cores, the efficiency of the parallel code as a whole …

Food Availability Modulates Temperature-Dependent Effects On Growth, Reproduction, And Survival In Daphnia Magna, Gustavo S. Betini, Xueqi Wang, Tal Avgar, Matthew M. Guzzo, John M. Fryxell

Wildland Resources Faculty Publications

Reduced body size and accelerated life cycle due to warming are considered major ecological responses to climate change with fitness costs at the individual level. Surprisingly, we know little about how relevant ecological factors can alter these life history trade‐offs and their consequences for individual fitness. Here, we show that food modulates temperature‐dependent effects on body size in the water flea Daphnia magna and interacts with temperature to affect life history parameters. We exposed 412 individuals to a factorial manipulation of food abundance and temperature, tracked each reproductive event, and took daily measurements of body size from each individual. High …

Interactions With Humans Shape Coyote Responses To Hazing, Julie K. Young, Edd Hammill, Stewart W. Breck

Wildland Resources Faculty Publications

Medium and large carnivores coexist with people in urban areas globally, occasionally resulting in negative interactions that prompt questions about how to reduce human-wildlife conflict. Hazing, i.e., scaring wildlife, is frequently promoted as an important non-lethal means for urbanites to reduce conflict but there is limited scientific evidence for its efficacy. We used a population of captive coyotes (Canis latrans) to simulate urban human-coyote interactions and subsequent effects of hazing on coyote behavior. Past experiences with humans significantly affected the number of times a coyote approached a human to necessitate hazing. Coyotes that had been hand fed by …

Climate Diagnostics Of The Extreme Floods In Peru During Early 2017, Rackhun Son, Shih-Yu Simon Wang, Wan-Ling Tseng, Christian W. Barreto Schuler, Emily Becker, Jin-Ho Yoon

Plants, Soils, and Climate Faculty Publications

From January through March 2017, a series of extreme precipitation events occurred in coastal Peru, causing severe floods with hundreds of human casualties and billions of dollars in economic losses. The extreme precipitation was a result of unusually strong recurrent patterns of atmospheric and oceanic conditions, including extremely warm coastal sea surface temperatures (SST) and weakened trade winds. These climatic features and their causal relationship with the Peruvian precipitation were examined. Diagnostic analysis and model experiments suggest that an atmospheric forcing in early 2017, which was moderately linked to the Trans-Niño Index (TNI), initiated the local SST warming along coastal …

Assessment Of Groundwater Resources In Siwa Oasis, Western Desert, Egypt, Noha H. Moghazy, Jagath J. Kaluarachchi

Civil and Environmental Engineering Faculty Publications

One of the major challenges facing Egypt is limited water resources associated with rapid increase in population. In 1960s, Egyptian government started to use groundwater from the Nubian Sandstone Aquifer System (NSAS) in the Western Desert to expand agricultural sector. Siwa Oasis is the focus of this study to assess the efficiency of groundwater use and corresponding impacts from 1980 to 2012. Results show that from 1980 to 1998, withdrawal from poorly designed wells increased rapidly causing an increase in excess water about 336%. The increase of excess water with the usage of poor drainage produced lakes. Remote Sensing showed …

Potentially Electric: An E-Textiles Project As A Model For Teaching Electric Potential, Doug Ball, Colby Tofel-Grehl

Teacher Education and Leadership Faculty Publications

Electric potential is one of the most challenging concepts taught in high school physics classes due to the abstract nature of the concept.¹ When taught, electric potential is often taught using a poorly triangulated set of instructional analogies, each possessing different strengths and limitations. Within this paper we share our learning from a two-week electronic textiles (e-textiles) unit designed to help students in an AP high school physics course improve their understanding of electric potential through the construction of a project entitled “The Slouching T-shirt” (STS) (Fig. 1). The STS project was part of a larger instructional unit on …

How Adolescents Use Text Messaging Through Their High School Years, Samuel E. Ehrenreich, Kurt J. Beron, Kaitlyn Burnell, Diana J. Meter, Marion K. Underwood

Human Development and Family Studies Faculty Publications

Co‐construction theory suggests adolescents use digital communication to address developmental challenges. For a sample of 214 ethnically diverse adolescents, this research used direct observation to investigate the frequency, content, and timing of texting with parents, peers, and romantic partners through grades 9–12. Analyses showed that texting frequency follows a curvilinear trajectory, peaking in eleventh grade. Adolescents discussed a range of topics, predominantly with peers. Communication with parents was less frequent, but consistent over time. Approximately 45‐65% of adolescents communicated with romantic partners, texting heavily and about topics similar to those discussed with peers. Texting may help adolescents navigate key developmental …

Snowpack Properties Vary In Response To Burn Severity Gradients In Montane Forests, Jordan Maxwell, Samuel B. St. Clair

Aspen Bibliography

Wildfires are altering ecosystems globally as they change in frequency, size, and severity. As wildfires change vegetation structure, they also alter moisture inputs and energy fluxes which influence snowpack and hydrology. In unburned forests, snow has been shown to accumulate more in small clearings or in stands with low to moderate forest densities. Here we investigate whether peak snowpack varies with burn severity or percent overstory tree mortality post-fire in a mid-latitude, subalpine forest. We found that peak snowpack across the burn severity gradients increased 15% in snow-water equivalence (SWE) and 17% in depth for every 20% increase in overstory …

Colorants In Cheese Manufacture: Production, Chemistry, Interactions, And Regulation, Prateek Sharma, Annalisa Segat, Alan L. Kelly, Jeremiah J. Sheehan

Nutrition, Dietetics, and Food Sciences Faculty Publications

Colored Cheddar cheeses are prepared by adding an aqueous annatto extract (norbixin) to cheese milk; however, a considerable proportion (∼20%) of such colorant is transferred to whey, which can limit the end use applications of whey products. Different geographical regions have adopted various strategies for handling whey derived from colored cheeses production. For example, in the United States, whey products are treated with oxidizing agents such as hydrogen peroxide and benzoyl peroxide to obtain white and colorless spray‐dried products; however, chemical bleaching of whey is prohibited in Europe and China. Fundamental studies have focused on understanding the interactions between colorants …

Antioxidant Activity Of Sesame Seed Lignans In Sunflower And Flaxseed Oils, S. Y. Hadeel, S. A. Khalida, M. K. Walsh

Nutrition, Dietetics, and Food Sciences Faculty Publications

This study investigated the antioxidant activity of crude lignan extracts and purified lignans (sesamin, sesamolin, and sesamol) in sunflower and flaxseed oils. Lignan extracts were prepared from roasted sesame seed oil (LRSO) and unroasted sesame seed oil (LUSO). Additionally, the individual lignans were purified from both oils. The crude extracts and purified lignans were added at concentrations of 0.01, 0.02 and 0.03% to the oils and stored at 25 and 65°C over time and peroxide values and thiobarbituric acid values were measured. Each oil showed an increase in oxidation over time, with the samples stored at 65°C exhibiting accelerated oxidation. …

A 100-M-Scale Modeling Study Of A Gale Event On The Lee Side Of A Long Narrow Mountain, Halie Xue, Jian Li, Tingting Qian, Hongping Gu

Plants, Soils, and Climate Faculty Publications

In this study, a gale event that occurred on the lee side of a long narrow mountain was investigated, together with the associated mountain flows, using a realistic-case large-eddy simulation (LES) that is based on the Weather Research and Forecasting Model. The mountain is located on the southeastern Tibetan Plateau, where approximately 58 gales occur annually, mostly in the afternoons during the winter season. Benefitting from realistic topography and high horizontal resolution as fine as 111 m, the LES can replicate features similar to the wind fields observed during the gale period. Investigation of the early morning wind structure over …

Evidence For Accelerated Weathering And Sulfate Export In High Alpine Environments, John T. Crawford, Eve-Lyn S. Hinckley, M. Iggy Litaor, Janice Brahney, Jason C. Neff

Watershed Sciences Faculty Publications

High elevation alpine ecosystems—the 'water towers of the world'—provide water for human populations around the globe. Active geomorphic features such as glaciers and permafrost leave alpine ecosystems susceptible to changes in climate which could also lead to changing biogeochemistry and water quality. Here, we synthesize recent changes in high-elevation stream chemistry from multiple sites that demonstrate a consistent and widespread pattern of increasing sulfate and base cation concentrations or fluxes. This trend has occurred over the past 30 years and is consistent across multiple sites in the Rocky Mountains of the United States, western Canada, the European Alps, the Icelandic …

Zika Virus Infection Causes Temporary Paralysis In Adult Mice With Motor Neuron Synaptic Retraction And Evidence For Proximal Peripheral Neuropathy, John D. Morrey, Alexandre L. R. Oliveira, Hong Wang, Katherine Zukor, Mateus Vidigal De Castro, Venkatraman Siddharthan

Animal, Dairy, and Veterinary Science Faculty Publications

Clinical evidence is mounting that Zika virus can contribute to Guillain-Barré syndrome which causes temporary paralysis, yet the mechanism is unknown. We investigated the mechanism of temporary acute flaccid paralysis caused by Zika virus infection in aged interferon αβ-receptor knockout mice used for their susceptibility to infection. Twenty-five to thirty-five percent of mice infected subcutaneously with Zika virus developed motor deficits including acute flaccid paralysis that peaked 8-10 days after viral challenge. These mice recovered within a week. Despite Zika virus infection in the spinal cord, motor neurons were not destroyed. We examined ultrastructures of motor neurons and synapses by …

Incorporation Of Unmanned Aerial Vehicle (Uav) Point Cloud Products Into Remote Sensing Evapotranspiration Models, Mahyar Aboutalebi, Alfonso F. Torres-Rua, Mac Mckee, William P. Kustas, Héctor Nieto, Maria Mar Alsina, Alex White, John H. Prueger, Lynn Mckee, Joseph Alfieri, Lawrence E. Hipps, Calvin Coopmans, Nick Dokoozlian

Civil and Environmental Engineering Faculty Publications

In recent years, the deployment of satellites and unmanned aerial vehicles (UAVs) has led to production of enormous amounts of data and to novel data processing and analysis techniques for monitoring crop conditions. One overlooked data source amid these efforts, however, is incorporation of 3D information derived from multi-spectral imagery and photogrammetry algorithms into crop monitoring algorithms. Few studies and algorithms have taken advantage of 3D UAV information in monitoring and assessment of plant conditions. In this study, different aspects of UAV point cloud information for enhancing remote sensing evapotranspiration (ET) models, particularly the Two-Source Energy Balance Model (TSEB), over …

Lin, Christopher Pennell, Alessandro Franchin, Ann M. Middlebrook, Dorothy L. Fibiger, Caroline C. Womack, Erin E. Mcduffie, Randy S. Martin, Kori D. Moore, Munkhbayar Baasandorj, Steven S. Brown

Civil and Environmental Engineering Faculty Publications

Ammonium-containing aerosols are a major component of wintertime air pollution in many densely populated regions around the world. Especially in mountain basins, the formation of persistent cold-air pools (PCAPs) can enhance particulate matter with diameters less than 2.5 µm (PM_2.5) to levels above air quality standards. Under these conditions, PM_2.5 in the Great Salt Lake region of northern Utah has been shown to be primarily composed of ammonium nitrate; however, its formation processes and sources of its precursors are not fully understood. Hence, it is key to understanding the emission sources of its gas phase precursor, ammonia …

Reflective Practice: The Impact Of Self-Identified Learning Gaps On Professional Development, Joanna C. Weaver, Matthew Ryan Lavery, Sarah Heineken

Journal on Empowering Teaching Excellence

The ebb and flow of education creates unique challenges within educational programming. Universities are charged with the directive to offer more diverse field experiences within their course requirements. As a result of the directive, not every topic nor instructional scenario can be addressed in the program coursework, challenging the programs to bridge the pedagogical learning gaps of their candidates. The purpose of the professional development (PD) being studied was to connect pedagogical methods to candidates’ own learning by providing self-selected PD with instructional tools that candidates could directly put into practice. The self-selected PD based on self-reflection of knowledge had …

Voting And Civic Engagement Among Utah Women, Susan R. Madsen, Robbyn T. Scribner

Marketing and Strategy Faculty Publications

Utah has a strong history of women’s political and civic involvement. The state was an early leader in giving women the vote, was home to the first female state senator in the nation (MacKay, 2005), and, as recently as 1996, had the strongest women’s voter participation in the United States (Davidson, 1996). However, these factors do not give the full picture; and in 2015 the Institute for Women’s Policy Research (2015) ranked Utah dead last in the area of political participation. Much of this ranking was due to the lack of women running for and serving in public office, but …

Labor Force Participation Among Utah Women, Susan R. Madsen, Robbyn T. Scribner

Marketing and Strategy Faculty Publications

Over the past half-century or so, Utah women’s participation in the labor force has steadily increased at a rate of about 8% per decade (Utah Women & Leadership Project, 2019). According to the most recent (2017) U.S. Census Bureau estimates, women in Utah make up 45% of the state workforce, which is slightly lower than the U.S. women’s share of the national workforce, 47.8% (United States Census Bureau, 2017a). In general, Utah women are about as likely to be employed as U.S. women, but Utah women are less likely to work full-time year-round (Department of Work-force Services, 2014). Numerous factors …

Utah Women And Stem, Susan R. Madsen, Elizabeth Goryunova, Robbyn T. Scribner

Marketing and Strategy Faculty Publications

Employment opportunities in Science, Technology, Engineering, and Math (STEM) sectors in Utah are estimated to reach 101,000 by 2018 (Carnevale, Smith, & Melton, 2011). These jobs are recognized nationwide as being well-compensated and generally recession-proof. Yet Utah women continue to hold a lower percentage of STEM-sec-tor jobs than women nationally; in fact, Utah is ranked last in the United States in terms of the percent of women employed in STEM. In addition, Utah women work in STEM occupations at a rate that is less than half that of Utah men (Institute for Women’s Policy Research (IWPR), 2013). Recognizing the role …

The Status Of Women In Utah Politics: Congress, Statewide Executive Offices, And The State Legislature, Susan R. Madsen, D. Candice Pierucci

Marketing and Strategy Faculty Publications

A host of national reports and media (e.g., Chu & Posner, 2013) in the past decade have ranked Utah last or near last in terms of women being in positions of decision making and leadership, and women in Utah politics is foundational to this issue. Raising awareness of the reasons why this is the case is critical to social change efforts focused on improving the representation of women in political roles within the state. Women serving in public office within the state of Utah have positive implications for women’s health. Research shows that when more women are involved in decision-making …

The Status Of Women In Utah Politics: Counties, Mayors, City Councils, And Boards Of Education, Susan R. Madsen, D. Candice Pierucci

Marketing and Strategy Faculty Publications

Several national reports earlier in the past decade ranked Utah last or near last in terms of women being in positions of decision making and leadership, including a 2013 Center for American Progress report titled “The State of Women in America: A 50-State Analysis of How Women Are Faring Across the Nation” (Chu & Posner, 2013). These and other rankings most often use the following four criteria: 1) gender wage gap, 2) educational attainment, 3) women in management roles, and 4) women serving in state legislatures. Research released through the Utah Women & Leadership Project and the Utah Women & …

Data-Driven Multiscale Modeling Reveals The Role Of Metabolic Coupling For The Spatio-Temporal Growth Dynamics Of Yeast Colonies, Jukka Intosalmi, Adrian C. Scott, Michelle Hays, Nicholas Flann, Olli Yli-Harja, Harri Lähdesmäki, Aimée M. Dudley, Alexander Skupin

Computer Science Faculty and Staff Publications

Background: Multicellular entities like mammalian tissues or microbial biofilms typically exhibit complex spatial arrangements that are adapted to their specific functions or environments. These structures result from intercellular signaling as well as from the interaction with the environment that allow cells of the same genotype to differentiate into well-organized communities of diversified cells. Despite its importance, our understanding how this cell–cell and metabolic coupling lead to functionally optimized structures is still limited.

Results: Here, we present a data-driven spatial framework to computationally investigate the development of yeast colonies as such a multicellular structure in dependence on metabolic capacity. For this …
