Atmospheric Refraction Corrections In Ground-To-Satellite Optical Time Transfer, Benjamin K. Stuhl

Space Dynamics Laboratory Publications

Free-space optical time and frequency transfer techniques can synchronize fixed ground stations at the femtosecond level, over distances of tens of kilometers. However, optical time transfer will be required to span intercontinental distances in order to truly unlock the performance of optical frequency standards and support an eventual redefinition of the SI second. Fiber dispersion and Sagnac uncertainty severely limit the performance of long-range optical time transfer over fiber networks, so satellite-based free-space time transfer is a promising solution. In pursuit of ground-to-space optical time transfer, previous work has considered a number of systematic shifts and concluded that all of …

Improving Skills In Computer Methods: Introductory Toolkit To Python For Undergraduate Physics Majors, Erin O'Donnell, Melissa Rasmussen

Physics Capstone Projects

The computer-based curriculum for undergraduate physics students before 2019 struggled to stay current and applicable. When the course was created in the early 2000s, MathCad was used daily by many physicists. As computer’s and their computational abilities have grown exponentially, so have programming languages and applications. Now in the late 2010s/early 2020s, Excel, Python, and Mathematica are some of the most common computer appliques. To address this, we created toolkits to give undergraduate physicists the experience for future classes, careers, and graduate school. This paper focuses on the process for creating the Python toolkit and overall class setup. Run on …

Revision: Overcoming A Paralyzing Fear, Kennan Thompson

Tutor's Column

Revision is a difficult task to undertake. In many cases, it is a fear that paralyzes students. There are many benefits to revision that students may not understand. This may be one reason why it is so intimidating for students to revise a paper. Tutors should help students recognize that revision allows them to see where they can improve content organization, notice grammatical errors, and be more confident in their writing. Tutors should also give students specific tips to make the revision process easier.

Prescribed Fire Alters Structure And Composition Of A Mid-Atlantic Oak Forest Up To Eight Years After Burning, Cody L. Dems, Alan H. Taylor, Erica A. H. Smithwick, Jesse K. Kreye, Margot W. Kaye

Aspen Bibliography

Background

Prescribed fire in Eastern deciduous forests has been understudied relative to other regions in the United States. In Pennsylvania, USA, prescribed fire use has increased more than five-fold since 2009, yet forest response has not been extensively studied. Due to variations in forest composition and the feedback between vegetation and fire, Pennsylvania deciduous forests may burn and respond differently than forests across the eastern US. We measured changes in forest structure and composition up to eight years after prescribed fire in a hardwood forest of the Ridge and Valley region of the Appalachian Mountains in central Pennsylvania.

Earth Day In A Year Of Reckoning., Rachel Robinson-Greene

Languages, Philosophy, and Communication Studies Faculty Publications

Last year’s Earth Day, April 22nd, 2020 was unique. The United States, the country where the now international holiday originated, had realized it was in the midst of a pandemic just a little more than a month earlier. Lockdowns and closures meant less travel and less pollution. We all got a chance to see a glimmer of what might happen if we in the West reduced our consumption, even if only for a short period of time. Carbon emissions were dramatically reduced. Animals roamed the landscape. We were provided with a poignant visual representation of exactly what we have done …

Constraining The Atmospheric Limb Of The Plastic Cycle, Janice Brahney, Natalie Mahowald, Marje Prank, Gavin Cornwell, Zbigniew Kilmont, Hitoshi Matsui, Kimberly Ann Prather

Watershed Sciences Faculty Publications

Plastic pollution is one of the most pressing environmental and social issues of the 21st century. Recent work has highlighted the atmosphere’s role in transporting microplastics to remote locations [S. Allen et al., Nat. Geosci. 12, 339 (2019) and J. Brahney, M. Hallerud, E. Heim, M. Hahnenberger, S. Sukumaran, Science 368, 1257–1260 (2020)]. Here, we use in situ observations of microplastic deposition combined with an atmospheric transport model and optimal estimation techniques to test hypotheses of the most likely sources of atmospheric plastic. Results suggest that atmospheric microplastics in the western United States are primarily derived from secondary re-emission …

Mancha Anular Necrótica Y Mancha De Verano Del Césped, Claudia Nischwitz, Kelly Kopp, Jaydee Gunnell, Kent Evans, Erin Frank, Celina Wille

All Current Publications

La mancha anular necrótica y mancha de verano del césped son enfermedades fúngicas que infectan los pastos de estación fría y causan síntomas similares. Los síntomas comienzan como un crecimiento deficiente y marchitez de las hojas, que se convierten en parches marrones obvios que varían de 1 a 3 pies de diámetro. Debido a los síntomas similares que se observan en la infección por ambos patógenos, se necesita un microscopio para diagnosticar adecuadamente cada enfermedad. El manejo de ambas enfermedades puede ser difícil y frecuentemente requiere una combinación de técnicas de control cultural, químico y varietal.

Utah Hay And Forage Grower Preferred Drought Management Strategies, Kynda R. Curtis, Tatiana Drugova, Ruby Ward

All Current Publications

This fact sheet, the third in a series of three, examines the preferred drought management strategies of hay and forage growers and how their preferences change depending on drought severity and expected yields. Severe drought in forage production causes crop damage and losses leading to decreases in yield and profitability for growers (Yost et al., 2019). Water shortages are also common, with restrictions on use commonly imposed, especially in the late summer months. Hence, extended drought poses a threat to agricultural productivity and the economies of rural and tribal areas in Utah.

Utah Livestock Producer Preferred Drought Management Strategies, Kynda R. Curtis, Tatiana Drugova, Ruby Ward

All Current Publications

This fact sheet, the second in a series of three, examines livestock producer preferred drought management strategies and how producer preferences change depending on drought severity and expected grazing efficiency. Severe drought in livestock production leads to decreases in feed availability, range or hay quality, and overall lower quality beef (Holupchinski et al., n.d.). Hence, drought increases production costs and producer dependence on imported feed. Thus, extended drought poses a threat to agricultural productivity and the economies of rural and tribal areas in Utah.
