Simulations Of Langmuir-Wave Emission By Magnetic Holes In The Solar Wind, Jingting Liu, Daniel Verscharen, Jesse Coburn, Jeffersson Agudelo, Kai Germaschewski, Hamish Reid, Georgios Nicolaou, Christopher Owen Mar 2024

Simulations Of Langmuir-Wave Emission By Magnetic Holes In The Solar Wind, Jingting Liu, Daniel Verscharen, Jesse Coburn, Jeffersson Agudelo, Kai Germaschewski, Hamish Reid, Georgios Nicolaou, Christopher Owen

Faculty Publications

Langmuir waves are frequently detected in the solar wind and affect the energetics of the plasma electrons. Previous observational studies have found Langmuir waves associated with magnetic holes in the solar wind. In our work, we aim to understand the connection between magnetic holes and these waves. The Langmuir instability is a well-known consequence of electron beams in plasmas. We use particle-in-cell (PIC) simulations of a collisionless electron-ion plasma in a magnetic hole structure. We study the triggering of Langmuir waves by inhomogeneous beam instabilities in this configuration. Our simulations reveal patterns that suggest that injecting a beam into the …

Examining The Impact Of Stream Permanence On Headwater Stream Carbon Emissions, Hannah D. Conroy, Erin R. Hotchkiss, Kaelin M. Cawley, Keli Goodman, Jeremy B. Jones, Wilfred M. Wollheim, David Butman

Faculty Publications

Quantifying headwater stream carbon emissions is important for our understanding of the global carbon cycle because these emissions (an estimated 0.93-1.15 Pg C year) can be substantial compared to the terrestrial flux. Headwater stream networks can have high emissions due to their coupling with the terrestrial environment and high turbulence with some estimates predicting headwater stream networks can contribute 70% of the global riverine stream emissions. These carbon emissions are challenging to predict, especially with regards to headwater stream network spatiotemporal heterogeneity. The majority of headwater streams exhibit changes in stream network area on a seasonal basis, and these locations …

The Myth Of Tightening Credit Rating Standards In The Market For Corporate Debt, Karolina Krystyniak, Viktoriya Staneva Mar 2024

The Myth Of Tightening Credit Rating Standards In The Market For Corporate Debt, Karolina Krystyniak, Viktoriya Staneva

Faculty Publications

This study revisits the existing evidence of a downward trend in credit rating standards indicating that CRAs have become more conservative over time. We find that the time-series variation in the proxy for rating standards is mostly driven by the market-based variables in the model, specifically market capitalization and idiosyncratic volatility. We examine an alternative specification of the model, incorporating risk characteristics of rated firms relative to those of the average firm in the economy, and find it to have a higher explanatory power. Most importantly, we find little evidence of increased conservatism over time, in contrast to prior studies.

Interactions Between Soil Mineral Composition And Particulate Organic Matter Mediate Bioavailable Nitrogen, Andrea Jilling, Marian Carrell, A Stuart Grandy, Rachel Hestrin, Marco Keiluweit, Erik Knatvold, Andrew Whitaker Mar 2024

Interactions Between Soil Mineral Composition And Particulate Organic Matter Mediate Bioavailable Nitrogen, Andrea Jilling, Marian Carrell, A Stuart Grandy, Rachel Hestrin, Marco Keiluweit, Erik Knatvold, Andrew Whitaker

Faculty Publications

Soil organic matter (SOM) can supply critical quantities of nitrogen (N) to plants, but fundamental questions remain regarding from what pools and by which processes plants and microbes obtain N. The source of bioavailable N is generally assigned to polymeric or particulate organic matter (POM), but in mineral soils, POM is often a minor pool of N and can be a poor predictor of bioavailable N or plant N uptake. Mounting evidence suggests mineral-associated organic matter (MAOM) is significantly more dynamic than previously assumed and may serve as an important source of N for plants and microbes. The abundance and …

Energy Transfer In The Solar Wind: The Interplay Between Turbulence And Kinetic Instabilities., Simon Opie, Daniel Verscharen, Christopher Chen, Christopher Owen, Philip A. Isenberg, Luca Sorriso-Valvo, Luca Franci, Lorenzo Matteini

Faculty Publications

Precisely how and where energy transfer between scales in the Solar Wind takes place remains an open question. We use the occurrence of conditions predicted by linear theory to promote the growth of kinetic instabilities, to infer how turbulence drives temperature anisotropies. We analyse Solar Orbiter data by applying the measure of local energy transfer (LET) derived from the Politano and Pouquet exact law to identify the relative distributions of energy transfer processes in the solar wind. We quantify these processes with the application of a radial rate of strain computed from single spacecraft data, a measure that we define …

Sub-L1 monitors are currently being researched in mission concepts for small satellites and may be deployed on distant retrograde orbits around the Earth in the future. Depending on the location of the sub-L1 monitor, the lead time for the arrival of coronal mass ejections (CMEs) and for determining their geo-effectiveness could be prolonged. If the sub-L1 monitor was to orbit the Earth at a distance of 0.05 AU, as is proposed for the MIIST mission, for example, Dst predictions could be made up to 5 hours in advance. The close encounter of STEREO-A and Wind from April 2023 to November …

In-situ measurements from the Sun-Earth Lagrangian L1 point typically provide a 20-minute to 1-hour advanced warning of incoming interplanetary (IP) shocks, magnetic clouds before impact at the nose of Earth's magnetopause. Sub-L1 monitors may provide measurements sunward of the L1 point to improve the lead times for such transients to several hours, and various mission architecture have been proposed for more than 25 years. Because CMEs and shocks do not propagate exactly radially, the location of such a monitor with respect to the Sun-Earth line is a key parameter to take into account when designing such missions. Here, we highlight …

The viability of organic dairy operations in the United States (US) relies on forage production. The objectives of this study were to (1) assess producer and farm information regarding current forage production practices and producer knowledge gaps and (2) identify forage research and educational needs of organic dairy producers across the US. A survey was distributed to 643 organic dairy producers across the US, with 165 respondents (26% response rate). A focus group consisting of extension professionals, university researchers and staff, consultants, dairy industry representatives and organic dairy producers was also consulted for forage research needs. Results showed that approximately …

M.S. in Leadership

The purpose of this paper is to delve into the challenges faced by virtual leaders and provide recommendations for overcoming those challenges in order to enhance team performance and engagement in a remote work setting. I selected this research because I started a new job at the height of covid-19 and I was sent home to do a job I had no idea how to do. My research aims to contribute to the development of practical guidelines for virtual leaders and organizations. The challenges include communication and collaboration, trust, rapport and information sharing, managing conflicts, a sense of belonging and …
