Radiation From An Oscillating Dipole In The Presence Of Photon-Sector Cpt And Lorentz Violation, Joshua O'Connor, Brett Altschul Feb 2024

Radiation From An Oscillating Dipole In The Presence Of Photon-Sector Cpt And Lorentz Violation, Joshua O'Connor, Brett Altschul

Faculty Publications

We examine one of the standard loci for studying electromagnetic wave emission - the radiation from an oscillating electric dipole - in a model in which the electromagnetic sector is modified to include novel CPT- and Lorentz-violating propagation effects involving a preferred axial vector background. We evaluate the vacuum-birefringent radiation fields, including nonperturbative terms where appropriate. In general, the energy momentum carried by the fields in this model is known to have a complicated nonperturbative structure, which cannot be captured by naive power-series expansions in the components of the preferred background vector. However, we nevertheless find that at the lowest …

Gauss Circle Problem Over Smooth Integers, Ankush Goswami Feb 2024

Gauss Circle Problem Over Smooth Integers, Ankush Goswami

School of Mathematical & Statistical Sciences Faculty Publications

For a positive integer 𝑛, let 𝑟2(𝑛) be the number of representations of 𝑛 as sums of two squares (of integers), where the convention is that different signs and different orders of the summands yield distinct representations. A famous result of Gauss shows that 𝑅(𝑥) ∶= ∑ 𝑛≤𝑥 𝑟2(𝑛) ∼ 𝜋𝑥. Let 𝑃(𝑛) denote the largest prime factor of 𝑛 and let 𝑆(𝑥, 𝑦) ∶= {𝑛 ≤ 𝑥 ∶ 𝑃(𝑛) ≤ 𝑦}. In this paper, we study the asymptotic behavior of 𝑅(𝑥, 𝑦) ∶= ∑ 𝑛∈𝑆(𝑥,𝑦) 𝑟2(𝑛) for various ranges of 2 ≤ 𝑦 ≤ 𝑥. For 𝑦 in a …

The Combined Role Of Microbes And Forages In Animal Productivity, K. Panke-Buisse Feb 2024

The Combined Role Of Microbes And Forages In Animal Productivity, K. Panke-Buisse

IGC Proceedings (1977-2023)

Agricultural systems, particularly ruminant systems, are underpinned by diverse, functional microbial communities—in the soil, forage, silo, and rumen. We have relied on the jobs they perform on our behalf, but only recently have we been able to look “under the hood” at the membership and mechanisms within these microbiomes and begin to think about optimization. Ensiling is a common method of forage preservation globally and represents a highly intensive intersection between forage and microbiology, which has been shown to have beneficial effects on forage quality and dairy animal performance. However, observations of enhanced productivity, especially in the context of inoculated …

Ruminant Agriculture: A Tool For Climate Change Mitigation, B. L. Peterson Munks, M. Rellaford, J. Shanahan, S. Urbanowitz, F. Wang, S. Wang, Y. Zhao, E. Bender

IGC Proceedings (1977-2023)

The quest to address and mitigate climate change has been dubbed a “wicked problem” as it involves many interconnected processes requiring a multifaceted, comprehensive approach. Animal agriculture contributes roughly 15% to CO2 equivalent (CO2e) emissions; as a result, a concerted effort is being made to develop and promote more climate-friendly production practices. These practices include species diversification in grasslands, improving grazing rotation, adding nitrogen amendments, and the use of feed additives to reduce enteric fermentation. Successful inter-seeding of legumes and deep-rooted native grasses increases soil organic carbon (SOC) pools in many systems by increasing the biological carbon inputs to the …

Birkinshaw, W. Truter

IGC Proceedings (1977-2023)

Poverty in the Central Highlands of Madagascar is partly driven by inefficient exploitation of native forages and poor livestock nutrition. Zebus are of importance as cultural symbols, but this tradition has grown disconnected from agricultural policy. This project is working with three central highland communities near the protected areas of Itremo, Ibity and Ankafobe, to boost rangeland productivity and trial management methods which will support key forage grasses and improve livestock nutrition. A severe nitrogen deficiency compounded by extremely acidic soil conditions and low phosphorus is observed across the three sites. The lowest grazing capacity of an estimated 0.7 livestock …

Economic Value Of Improving Feed Efficiency Of Beef Cows On Pasture, J. T. Biermacher, J. K. Rogers, D. Lalman, A. Holder, R. S. Walker Feb 2024

Economic Value Of Improving Feed Efficiency Of Beef Cows On Pasture, J. T. Biermacher, J. K. Rogers, D. Lalman, A. Holder, R. S. Walker

IGC Proceedings (1977-2023)

Dry matter intake of beef cows is based on a percentage of body weight, so as mature cow size increases, intake increases. Feed efficiency, or the amount of feed required to produce gain or maintain production, has a direct impact to the producer. That is, as mature cow weight increases, yearly maintenance costs increases due to higher feed costs. However, variation in feed efficiency exists within population. Some large cows consume the same or less dry matter as a smaller cow, but produce a larger calf. Conversly, some smaller cows consume the same or more as a large cow but …
