Introduction: Because Genomic selection (GS) is a predictive methodology, it needs to guarantee high-prediction accuracies for practical implementations. However, since many factors affect the prediction performance of this methodology, its practical implementation still needs to be improved in many breeding programs. For this reason, many strategies have been explored to improve the prediction performance of this methodology. Methods: When environmental covariates are incorporated as inputs in the genomic prediction models, this information only sometimes helps increase prediction performance. For this reason, this investigation explores the use of feature engineering on the environmental covariates to enhance the prediction performance of genomic …


Teaching Difficult Topics: Reflections From The Undergraduate Music Classroom, Olivia R. Lucas, Laura Moore Pruett Jan 2024

Teaching Difficult Topics: Reflections From The Undergraduate Music Classroom, Olivia R. Lucas, Laura Moore Pruett

Faculty Publications

Teaching Difficult Topics provides a series of on-the-ground reflections from college music instructors working in a wide variety of institutional settings about their approaches to inclusive, supportive pedagogy in the music classroom. Although some imagine the music classroom to be an apolitical space, instructors find themselves increasingly in need of resources for incorporating issues of race and ethnicity, gender and sexuality, and historical trauma into their classrooms in ways that support student learning and safeguard their classroom communities. The teaching reflections in Teaching Difficult Topics examine difficult themes that fall into three primary categories: subjects that instructors sense to be …

Faculty Publications

A novel binary compound within the Ba–Sb phase diagram, Ba5Sb8, was synthesized by combining elements with an excess of Sb in an alumina crucible. Structural elucidation was performed using single-crystal X-ray diffraction. This compound crystallizes in the orthorhombic space group Fdd2 with unit cell parameters of a = 15.6568(13) Å, b = 35.240(3) Å, c = 6.8189(6) Å, adopting its own structure type. The most distinctive features of the structure are the eight-membered [Sb8]10− polyanionic fragments which have no known precedents among antimonides. They are separated by five Ba2+ cations, which afford the charge balance and enable adherence …


Enriched Molecular-Level View Of Saline Wetland Soil Carbon By Sensitivity-Enhanced Solid-State Nmr, Wancheng Zhao, Elizabeth C. Thomas, Debkumar Debnath, Faith J. Scott, Frederic Mentink-Vigier, John R. White, Robert L. Cook, Tuo Wang Jan 2024

Enriched Molecular-Level View Of Saline Wetland Soil Carbon By Sensitivity-Enhanced Solid-State Nmr, Wancheng Zhao, Elizabeth C. Thomas, Debkumar Debnath, Faith J. Scott, Frederic Mentink-Vigier, John R. White, Robert L. Cook, Tuo Wang

Faculty Publications

Soil organic matter (SOM) plays a major role in mitigating greenhouse gas emission and regulating earth’s climate, carbon cycle, and biodiversity. Wetland soils account for one-third of all SOM; however, globally, coastal wetland soils are eroding faster due to increasing sea-level rise. Our understanding of carbon sequestration dynamics in wetlands lags behind that of upland soils. Here, we employ solid-state nuclear magnetic resonance (ssNMR) to investigate the molecular-level structure of biopolymers in wetland soils spanning 11 centuries. High-resolution multidimensional spectra, enabled by dynamic nuclear polarization (DNP), demonstrate enduring preservation of molecular structures within herbaceous plant cores, notably condensing aromatic motifs …

Battaile, Leo Fontenot, Fabrizio Donnarumma, Scott Lovell, Mario Rivera Jan 2024

Pseudomonas Aeruginosa Gene Pa4880 Encodes A Dps-Like Protein With A Dps Fold, Bacterioferritin-Type Ferroxidase Centers, And Endonuclease Activity, Nimesha Rajapaksha, Huili Yao, Aisha Cook, Steve Seibold, Lijun Liu, Kevin P. Battaile, Leo Fontenot, Fabrizio Donnarumma, Scott Lovell, Mario Rivera

Faculty Publications

We report the biochemical, structural, and functional characterization of the protein coded by gene PA4880 in the P. aeruginosa PAO1 genome. The PA4880 gene had been annotated as coding a probable bacterioferritin. Our structural work shows that the product of gene PA4880 is a protein that adopts the Dps subunit fold, which oligomerizes into a 12-mer quaternary structure. Unlike Dps, however, the ferroxidase di-iron centers and iron coordinating ligands are buried within each subunit, in a manner identical to that observed in the ferroxidase center of P. aeruginosa bacterioferritin. Since these structural characteristics correspond to Dps-like proteins, we term the …

The Role Of Holistic Mentoring Ecosystems In Mitigating Covid-19 Pandemic Impacts On The Persistence Of Low-Income Stem Students, Raeshan D. Davis, Zakiya S. Wilson-Kennedy

Faculty Publications

Holistic mentoring ecosystems are a comprehensive approach to addressing the diverse needs of students through interconnected support networks. While mentoring has been well-documented in existing literature, more research is needed to determine the effectiveness of mentoring ecosystems in mitigating the impact of critical junctures for vulnerable, high-attrition student populations. Guided by Tinto’s model of retention, this qualitative case study investigated the role of holistic mentoring ecosystems in mitigating the impacts of the two combined critical junctures—the COVID-19 pandemic and the first year of college—on low-income STEM undergraduates. Our findings suggest that holistic mentoring ecosystems were essential in helping students adjust …


Upper Bounds For The Lagrangian Cobordism Relation On Legendrian Links, Joshua M. Sabloff, David Shea Vela-Vick, C. M.Michael Wong Jan 2024

Upper Bounds For The Lagrangian Cobordism Relation On Legendrian Links, Joshua M. Sabloff, David Shea Vela-Vick, C. M.Michael Wong

Faculty Publications

Lagrangian cobordism induces a preorder on the set of Legendrian links in any contact 3–manifold. We show that any finite collection of null-homologous Legendrian links in a contact 3–manifold with a common rotation number has an upper bound with respect to the preorder. In particular, we construct an exact Lagrangian cobordism from each element of the collection to a common Legendrian link. This construction allows us to define a notion of minimal Lagrangian genus between any two null-homologous Legendrian links with a common rotation number.

Craig, traces the circuit split on the use of two-way video communication in criminal trials, and concludes with a review of state cases where the protections of the Confrontation Clause are evaluated with the use of Zoom testimony.


Loan To Own, Robert W. Miller Jan 2024

Loan To Own, Robert W. Miller

Faculty Publications

Convertible debtor-in-possession ("DIP") financing is symptomatic of a paradigm shift in the control of large bankruptcy cases. During the prior era of lender control, distressed investors used DIP financing to shape the trajectory of bankruptcy cases and extract monopolistic rents at the expense of other constituencies. Enter the original loan-to-own: a common strategy commenced with a DIP loan, continued with a stalking-horse bid, and culminated in an acquisition of the debtor's assets. More recently, private equity sponsors ("Sponsors") and other sophisticated insiders are usurping control of bankruptcy cases. Convertible DIP financing (Loan-to-Own 2.0) is a byproduct. This Article situates convertible …


Everyone Is Talking About Bankruptcy Directors, Robert W. Miller Jan 2024

Everyone Is Talking About Bankruptcy Directors, Robert W. Miller

Faculty Publications

The proliferation of bankruptcy directors represents a controversial shift in the corporate governance landscape. Delegating corporate decision making to bankruptcy directors insulates conflicted transactions and claims from the elevated scrutiny provided by derivative standing and entire fairness. However, critics have questioned their independence and cleansing effect. Are bankruptcy directors really independent when their role includes negotiation with and/or investigation into the same parties who appoint them? Should their decisions be given deference when their appointment is associated with lower recoveries for creditors? Bankruptcy directors' salience is best illustrated by the numerous proposals for determining whether they have cleansing effect, including …

R.I.P. Rap, Thomas Simmons Jan 2024

R.I.P. Rap, Thomas Simmons

Faculty Publications

In 1983, South Dakota's Legislature confirmed that the Rule Against Perpetuities ("RAP") was neutralized: "The common-law rule against perpetuities is not in force in this state." The legislative pronouncement, essentially unnoticed at the time, proved to be the seed from which the state's trust industry grew. This article, the second of two installments, continues the life history of RAP in South Dakota. The first installment surveyed common law RAP and its obscure, labyrinthine, counter-intuitive mechanics. This installment picks up with a survey of pre-1983 caselaw and uncovers an interesting nugget-it appears that South Dakota never recognized RAP in the first …


Politicians The Founders Warned You About, Neil Fulton Jan 2024

Politicians The Founders Warned You About, Neil Fulton

Faculty Publications

Many articles have explored the Founders' intentions regarding the constitutional text. Much less attention has focused on the Founders' ideas regarding the traits needed of the leaders in a constitutional republic. The Constitution focuses on governing structures, many of which relate to the electoral process. The Constitution does not spell out the ideal traits of the leaders elected pursuant to those processes. Nonetheless, the Founders possessed clear views about the virtues and qualifications that ideal political leaders required. Indeed, the Founders issued warnings about certain archetypal political figures who, because of their flagrant disregard of the ideal virtues and qualifications, …

Legislative Oversight Of The Administrative State: The South Dakota Legislature's Review Of Agency Rules, Neil Fulton, Patrick Garry, Gabrielle Unruh

Faculty Publications

Like the federal government, the executive branch of South Dakota's government includes administrative agencies. But unlike the federal government, the South Dakota Legislature exercises greater oversight. One such example is the Legislative Interim Rules Review Committee. This article not only explains the purpose of the Committee and the rules review process, but it also describes the results of an empirical study that analyzed the Committee's level of involvement in administrative rules' promulgation. In particular, this study examined the Committee's actions during the calendar year of 2019-whether the rules were reverted, passed, or later passed with modifications, and why such actions …

Assessing A Potential Deviation In The Legislative Process: The Use Of Vehicle Bills In South Dakota, Neil Fulton, Sarah Kammer, Patrick Garry Jan 2024

Assessing A Potential Deviation In The Legislative Process: The Use Of Vehicle Bills In South Dakota, Neil Fulton, Sarah Kammer, Patrick Garry

Faculty Publications

Vehicle bills are used by many state legislatures, including the South Dakota Legislature. These bills serve as empty shells to be amended with substantive text later in the legislative session. Critics charge that such vehicles allow legislators to meet the filing deadline with an essentially meaningless bill that gets amended late in the session, thereby depriving the public and opposition legislators from adequately investigating and debating the newly amended bill. This article examines how, and to what extent, the South Dakota Legislature has used vehicle bills over the past decade. In so doing, the article may provide some insight into …

The Nondelegation Doctrine In The States: How The Doctrine Has Been Applied In South Dakota, Patrick Garry, Gabrielle Unruh Jan 2024

The Nondelegation Doctrine In The States: How The Doctrine Has Been Applied In South Dakota, Patrick Garry, Gabrielle Unruh

Faculty Publications

The United States Constitution's separation of powers doctrine is foundational to the operation of the United States government. In theory, the nondelegation doctrine exists to preserve the separation of powers amongst the three branches of government. The doctrine's purpose is to give sole lawmaking authority to Congress, while yet allowing it to delegate rulemaking authority to an administrative agency, but only if it provides an "intelligible principle" to guide and constrain the agency's rulemaking. While on the surface this appears to be a high standard, the United States Supreme Court has not struck down a law promulgated by an administrative …


Reinvigorating Congress's Role In The Administrative State: What The Major Questions Doctrine Suggests About Nondelegation, Patrick Garry, Sidney J. Hardy Jan 2024

Reinvigorating Congress's Role In The Administrative State: What The Major Questions Doctrine Suggests About Nondelegation, Patrick Garry, Sidney J. Hardy

Faculty Publications

In its recent decision in West Virginia v. EPA, the U.S. Supreme Court struck down administrative rules attempting to dramatically transform the electrical power generating industry. The Court's decision rested on its major questions doctrine, which states that on important enough matters the intent of Congress must be clearly expressed. This doctrine goes against the prevailing trend of deference toward the administrative state, as expressed through the permissive nondelegation and Chevron doctrines. While the major questions doctrine seeks to retain some congressional control over important issues, it nonetheless attracts much criticism on an array of grounds. This article proposes an …


Timing And Evolution Of Structures Within The Southeastern Greater Caucasus And Kura Fold-Thrust Belt From Multiproxy Sediment Provenance Records, Adam M. Forte, Eric S. Cowgill, Dawn Y. Sumner, Dominique I. Garello, Nathan A. Niemi, K. Colton Fowler Jan 2024

Timing And Evolution Of Structures Within The Southeastern Greater Caucasus And Kura Fold-Thrust Belt From Multiproxy Sediment Provenance Records, Adam M. Forte, Eric S. Cowgill, Dawn Y. Sumner, Dominique I. Garello, Nathan A. Niemi, K. Colton Fowler

Faculty Publications

The Greater Caucasus (GC) mountains are the locus of post-Pliocene shortening within the northcentral Arabia-Eurasia collision. Although recent low-temperature thermochronology constrains the timing of orogen formation, the evolution of major structures remains enigmatic—particularly regarding the internal kinematics within this young orogen and the associated Kura Fold-Thrust Belt (KFTB), which flanks its southeastern margin. Here we use a multiproxy provenance analysis to investigate the tectonic history of both the southeastern GC and KFTB by presenting new data from a suite of sandstone samples from the KFTB, including sandstone petrography, whole-rock geochemistry, and detrital zircon (DZ) U-Pb geochronology. To define source terranes …


Molecular And Cellular Programs Underlying The Development Of Bovine Pre-Implantation Embryos, Zongliang Jiang Jan 2024

Molecular And Cellular Programs Underlying The Development Of Bovine Pre-Implantation Embryos, Zongliang Jiang

Faculty Publications

Early embryonic mortality is a major cause of infertility in cattle, yet the underlying molecular causes remain a mystery. Over the past half century, assisted reproductive technologies such as in vitro fertilisation and somatic cell nuclear transfer have been used to improve cattle reproductive efficiency; however, reduced embryo developmental potential is seen compared to their in vivo counterparts. Recent years have seen exciting progress across bovine embryo research, including genomic profiling of embryogenesis, new methods for improving embryo competence, and experimenting on building bovine embryos from stem cell cultures. These advances are beginning to define bovine embryo molecular and cellular …

Faculty Publications

This study addresses the limitations of Transformer models in image feature extraction, particularly their lack of inductive bias for visual structures. Compared to Convolutional Neural Networks (CNNs), the Transformers are more sensitive to different hyperparameters of optimizers, which leads to a lack of stability and slow convergence. To tackle these challenges, we propose the Convolution-based Efficient Transformer Image Feature Extraction Network (CEFormer) as an enhancement of the Transformer architecture. Our model incorporates E-Attention, depthwise separable convolution, and dilated convolution to introduce crucial inductive biases, such as translation invariance, locality, and scale invariance, into the Transformer framework. Additionally, we implement a …

Faculty Publications

At present, super-resolution algorithms are employed to tackle the challenge of low image resolution, but it is difficult to extract differentiated feature details based on various inputs, resulting in poor generalization ability. Given this situation, this study first analyzes the features of some feature extraction modules of the current super-resolution algorithm and then proposes an adaptive feature fusion block (AFB) for feature extraction. This module mainly comprises dynamic convolution, attention mechanism, and pixel-based gating mechanism. Combined with dynamic convolution with scale information, the network can extract more differentiated feature information. The introduction of a channel spatial attention mechanism combined with …
