Distribution And Trends Of Endemic Hawaiian Waterbirds, Eben H. Paxton, Kevin Brinck, Adonia Henry, Afsheen Siddiqi, Rachel Rounds, Jennifer Chutz

United States Geological Survey: Staff Publications

Four endemic species of wetland-dependent waterbirds occur on the main Hawaiian Islands, all of which have experienced sharp population declines and are listed as endangered species. Twice per year, state-wide surveys are conducted to count waterbirds, but these surveys are evaluated only infrequently. We used a state-space approach to evaluate long-term (1986–2016) and short-term (2006–2016) trends and current distribution and abundance of endemic Hawaiian waterbirds. The most numerous species was the Ae‘o, or Hawaiian Stilt (Himantopus mexicanus knudseni), with a 5-year estimated average abundance of 1,932 individuals, followed by ‘Alae Ke‘oke‘o, or Hawaiian Coot (Fulica alai), …

Structure Of Clostridium Perfringens Type Iv Pili, Alexander R. Meyer

Honors Program: Senior Projects (Public)

Type IV pili (T4P) are thin, hair-like bacterial appendages composed of protein subunits polymerized into a helical fiber. T4P perform diverse functions such as host cell adhesion, biofilm formation, natural competence, and twitching motility. While T4P are well characterized in Gram-negative bacteria, they have more recently been found in Gram-positive bacteria as well. In this work we aimed to solve the crystal structure of the type IV major pilin protein PilA2 from Clostridium perfringens, the predominant pilus subunit which makes up about 99% of the pilus fiber. We report expression, purification, and crystallization conditions which are sufficient for X-ray …

Perceptions Of Black Lives Matter: An Analysis Of The Movement And Its Impact On The Relationship Between The Lincoln Police Department, The Media And The Public, Paige Heinemann

Honors Program: Senior Projects (Public)

This study examines the relationships between the Lincoln Police Department (LPD), the Lincoln Journal Star (LJS), and the public as they interacted during the Black Lives Matter protests in Lincoln, Nebraska, during June 2020. In order to analyze the relationships between the three actors, I utilized previous research that examined the role of the media on perceptions of police, how media framing of police brutality influences perceptions, and how the four models of public relations function in communities. This led me to pose the following research question: How do the relationships between the Lincoln Police Department, the media and the …

Conservation Management Improves Agroecosystem Function And Resilience Of Soil Nitrogen Cycling In Response To Seasonal Changes In Climate, Lidong Li, Julie Konkel, Virginia L. Jin, Sean M. Schaeffer

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Understanding how conservation agricultural management improves soil nitrogen (N) stability in the face of climate change can help increase agroecosystem productivity and mitigate runoff, leaching and downstream water quality issues. We conducted a 2-year field study in a 36-year-old rain-fed cotton production system to evaluate the impacts of changing climatic factors (temperature and precipitation) on soil N under conservation management, including moderate inorganic N fertilizer application (0 and 67 kg N ha⁻¹ ), winter cover crops (fallow; winter wheat, Triticum aestivum L.; hairy vetch, Vicia villosa Roth), and reduced tillage (no-till; disk tillage). Structural equation modeling (SEM) was used …

De Novo Assembly And Annotation Of The North American Bison (Bison Bison) Reference Genome And Subsequent Variant Identification, L K. Dobson, A Zimin, D Bayles, E Fritz-Waters, D Alt, S Olsen, J Blanchong, J Reecy, T Pl Smith, J N. Derr

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Genomic tools have improved the ability to manage bison populations and enhanced efforts to conserve this iconic species. These tools have been particularly useful for detecting introgression of cattle genome within bison herds but are limited by the need to use the cattle genome as a surrogate for mapping reads. This complicates efforts to distinguish the species of origin of chromosomal segments in individual bison at the genomic level. An assembly (Bison_UMD1.0) based on 75X genome coverage by Illumina and 454 reads was generated using the MaSuRCA assembler, generating a 2.81 Gigbases de novo reference genome from American bison. Comparison …

The Influence Of Childhood Socioeconomic Status And Community Type On Visuospatial Attention Scores In Young Adulthood, Sophia C. Menting

Honors Program: Senior Projects (Public)

The purpose of this study was to investigate the relationship between various childhood experiences and young adult visuospatial attention scores. In particular, this study investigated factors such as where participants grew up (rural or urban community), childhood socio- economic status (SES) and how these factors relate to cognitive control, i.e., control of attention and impulsivity, in young adulthood. The sample consisted of 84 college students. There was no direct relationship between SES and visuospatial attention; however, there was a significant interaction with type of community such that young adults raised in low-SES families in rural communities had lower scores than …

Microbial Community Field Surveys Reveal Abundant Pseudomonas Population In Sorghum Rhizosphere Composed Of Many Closely Related Phylotypes, Dawn Chiniquy, Elle M. Barnes, Jinglie Zhou, Kyle Hartman, Xiaohui Li, Amy Sheflin, Ellen Marsh, Jessica Prenni, Adam M. Deutschbauer, Daniel P. Schachtman, Susannah G. Tringe

Department of Agronomy and Horticulture: Faculty Publications

While the root-associated microbiome is typically less diverse than the surrounding soil due to both plant selection and microbial competition for plant derived resources, it typically retains considerable complexity, harboring many hundreds of distinct bacterial species. Here, we report a time-dependent deviation from this trend in the rhizospheres of field grown sorghum. In this study, 16S rRNA amplicon sequencing was used to determine the impact of nitrogen fertilization on the development of the root-associated microbiomes of 10 sorghum genotypes grown in eastern Nebraska. We observed that early rhizosphere samples exhibit a significant reduction in overall diversity due to a high …

Evaluating Person-Centered Factors Associated With Brain–Computer Interface Access To A Commercial Augmentative And Alternative Communication Paradigm, Kevin Pitt, Jonathan S. Brumberg

Department of Special Education and Communication Disorders: Faculty Publications

Current BCI-AAC systems largely utilize custom-made software and displays that may be unfamiliar to AAC stakeholders. Further, there is limited information available exploring the heterogenous profiles of individuals who may use BCI-AAC. Therefore, in this study, we aimed to evaluate how individuals with amyotrophic lateral sclerosis (ALS) learned to control a motor-based BCI switch in a row-column AAC scanning pattern, and person-centered factors associated with BCI-AAC performance. Four individuals with ALS completed 12 BCI-AAC training sessions, and three individuals without neurological impairment completed 3 BCI-AAC training sessions. To assess person-centered factors associated with BCI-AAC performance, participants completed both initial and …

Exploiting Pull-In/Pull-Out Hysteresis In Electrostatic Mems Sensor Networks To Realize A Novel Sensing Continuous-Time Recurrent Neural Network, Mohammad H. Hasan, Amin Abbasalipour, Hamed Nikfarjam, Siavash Pourkamali, Muhammad Emad-Un-Din, Roozbeh Jafari, Fadi Alsaleem

Durham School of Architectural Engineering and Construction: Faculty Publications

The goal of this paper is to provide a novel computing approach that can be used to reduce the power consumption, size, and cost of wearable electronics. To achieve this goal, the use of microelectromechanical systems (MEMS) sensors for simultaneous sensing and computing is introduced. Specifically, by enabling sensing and computing locally at the MEMS sensor node and utilizing the usually unwanted pull in/out hysteresis, we may eliminate the need for cloud computing and reduce the use of analog-to-digital converters, sampling circuits, and digital processors. As a proof of concept, we show that a simulation model of a network of …

A Kinesiological Analysis Of Dancers At The University Of Nebraska-Lincoln, Vanessa Reiser

Honors Program: Senior Projects (Public)

Supplemental conditioning can improve a dancer’s performance of important skills without taking away from class and rehearsal time. To investigate this further, an individualized conditioning plan based on a specific skill was created for eight student dancers, and the effects were analyzed using a survey and rating scale by a trained dance professor. The results showed improvement of skills for the majority of dancers, along with improved fitness in qualities such as strength and balance. In conclusion, individualized conditioning plans based on a specific skill may benefit student dancers who are juggling intense class and rehearsal schedules.

Deep-Learning-Based Multivariate Pattern Analysis (Dmvpa): A Tutorial And A Toolbox, Karl M. Kuntzelman, Jacob M. Williams, Phui Cheng Lim, Ashtok Samal, Prahalada K. Rao, Matthew R. Johnson

Center for Brain, Biology, and Behavior: Faculty Publications

In recent years, multivariate pattern analysis (MVPA) has been hugely beneficial for cognitive neuroscience by making new experiment designs possible and by increasing the inferential power of functional magnetic resonance imaging (fMRI), electroencephalography (EEG), and other neuroimaging methodologies. In a similar time frame, “deep learning” (a term for the use of artificial neural networks with convolutional, recurrent, or similarly sophisticated architectures) has produced a parallel revolution in the field of machine learning and has been employed across a wide variety of applications. Traditional MVPA also uses a form of machine learning, but most commonly with much simpler techniques based on …

Nonvolatile Voltage Controlled Molecular Spin‐State Switching For Memory Applications, Thilini K. Ekanayaka, Guanhua Hao, Aaron Mosey, Ashley S. Dale, Xuanyuan Jiang, Andrew J. Yost, Keshab R.

Nonvolatile, molecular multiferroic devices have now been demonstrated, but it is worth giving some consideration to the issue of whether such devices could be a competitive alternative for solid-state nonvolatile memory. For the Fe (II) spin crossover complex [Fe{H₂B(pz)₂}₂(bipy)], where pz = tris(pyrazol-1-yl)-borohydride and bipy = 2,20-bipyridine, voltage-controlled isothermal changes in the electronic structure and spin state have been demonstrated and are accompanied by changes in conductance. Higher conductance is seen with [Fe{H₂B(pz)₂}₂(bipy)] in the high spin state, while lower conductance occurs for the low spin state. Plausibly, …

A Reference Genome Assembly Of Simmental Cattle, Bos Taurus Taurus, Michael P. Heaton, Timothy P.L. Smith, Derek M. Bickhart, Brian L. Vander Ley, Larry A. Kuehn, Jonas Oppenheimer, Wade R. Shafer, Fred T. Schuetze, Brad Stroud, Jennifer C. Mcclure, Jennifer P. Barfield, Harvey D. Blackburn, Theodore S. Kalbfleisch, Kimberly M. Davenport, Kristen L. Kuhn, Richard E. Green, Beth Shapiro, Benjamin D. Rosen

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Genomics research has relied principally on the establishment and curation of a reference genome for the species. However, it is increasingly recognized that a single reference genome cannot fully describe the extent of genetic variation within many widely distributed species. Pangenome representations are based on high-quality genome assemblies of multiple individuals and intended to represent the broadest possible diversity within a species. A Bovine Pangenome Consortium (BPC) has recently been established to begin assembling genomes from more than 600 recognized breeds of cattle, together with other related species to provide information on ancestral alleles and haplotypes. Previously reported de novo …

Kuehn, Jennifer C. Mcclure, Jennifer P. Barfield, Harvey D. Blackburn, Theodore S. Kalbfleisch, Derek M. Bickhart, Kimberly M. Davenport, Kristen L. Kuhn, Richard E. Green, Beth Shapiro, Timothy P.L. Smith

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Bison are an icon of the American West and an ecologically, commercially, and culturally important species. Despite numbering in the hundreds of thousands today, conservation concerns remain for the species, including the impact on genetic diversity of a severe bottleneck around the turn of the 20th century and genetic introgression from domestic cattle. Genetic diversity and admixture are best evaluated at genome-wide scale, for which a high-quality reference is necessary. Here, we use trio binning of long reads from a bison-Simmental cattle (Bos taurus taurus) male F1 hybrid to sequence and assemble the genome of the American plains bison (Bison …

Leaf-level gas exchange data support the mechanistic understanding of plant fluxes of carbon and water. These fluxes inform our understanding of ecosystem function, are an important constraint on parameterization of terrestrial biosphere models, are necessary to understand the response of plants to global environmental change, and are integral to efforts to improve crop production. Collection of these data using gas analyzers can be both technically challenging and time consuming, and individual studies generally focus on a small range of species, restricted time periods, or limited geographic regions. The high value of these data is exemplified by the many publications that …

Part-Scale Thermal Simulation Of Laser Powder Bed Fusion Using Graph Theory: Effect Of Thermal History On Porosity, Microstructure Evolution, And Recoater Crash, Reza Yavari, Ziyad Smoqi, Alex Riensche, Ben Bevans, Humaun Kobir, Heimdall Mendoza, Hyeyun Song, Kevin Cole, Prahalada Rao

Department of Mechanical and Materials Engineering: Faculty Publications

Flaw formation in laser powder bed fusion (LPBF) is influenced by the spatiotemporal temperature distribution – thermal history – of the part during the process. Therefore, to prevent flaw formation there is a need for fast and accurate models that can predict the thermal history as a function of the part shape and processing parameters. In previous work, a thermal modeling approach based on graph theory was used to predict the thermal history in LPBF parts in less-than 20% of the time required by finite element-based models with error within 10% of experimental measurements. The present work transitions toward the …

On Road Coordinates For Autonomous Vehicle Guidance, Ricardo Jacome

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

A new roadmap framework is proposed to improve the guidance and trajectory prediction capabilities of connected and automated vehicles (CAVs). Independent of road shape determination through external sensors, the system serves as a backup for challenging conditions, such as low sensor visibility and adverse environmental effects (e.g., rain, fog, snow). Based on the fusion of vehicle dynamics principles, differential geometry, and road design standards, the roadmap framework provides a consolidated collection of critical reference points of roadway centerlines and information about the shape of the roadway in the vicinity of a vehicle, including curvature, optimal travel velocity, and road alignment …

Development Of An Internet Of Things (Iot) Enabled Novel Wireless Multi Sensor Network For Infield Crop Monitoring, Nipuna Chamara

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Multispectral imaging systems on satellite, aerial, and ground platforms are used commonly to monitor in-field crops in precision agriculture by farmers and researchers. Limited spatial and temporal resolution and weather dependence of the data collection are two main disadvantages of these methods. In-field sensor networks can continuously monitor environmental and plant physiological parameters by leveraging low-power computation and long-range communication technologies. We built and tested a novel sensor network equipped with soil moisture, multispectral and RGB imaging sensors in an experimental soybean field at Eastern Nebraska Research and Extension Center, NE, USA. 10 down-looking and 1 up-looking sensor node were …

Avoiding The Basilisk: An Evaluation Of Top-Down, Bottom-Up, And Hybrid Ethical Approaches To Artificial Intelligence, Cole Shardelow

Honors Program: Senior Projects (Public)

This thesis focuses on three specific approaches to implementing morality into artificial superintelligence (ASI) systems: top-down, bottom-up, and hybrid approaches. Each approach defines both the mechanical and moral functions an AI would attain if implemented. While research on machine ethics is already scarce, even less attention has been directed to which of these three prominent approaches would be most optimal in producing a moral ASI and avoiding a malevolent AI. Thus, this paper argues of the three machine ethics approaches, a hybrid model would best avoid the problems of superintelligent AI because it minimizes the problems of bottom-up and top-down …

Oxygen Binding Thermodynamics Of Human Hemoglobin In The Red Blood Cell, Kyle K. Hill

Department of Chemistry: Dissertations, Theses, and Student Research

We report for the first time the binding constants and Hill numbers for oxygen in the red blood cell under physiological conditions. When compared to our results for hemoglobin in solution, our results show conclusively that hemoglobin binds oxygen more tightly and with lower co-operativity when packed in the red blood cell. At 18°C, these differences are striking: the respective half-saturation values are 15.57 µM (in red blood cells) and 18.83 µM (in solution), with corresponding Hill numbers of 2.475 (in red blood cells) and 2.949 (in solution). The optical complications that arise from high turbidity of red blood cell …

Ecosystem-Scale Biogeochemical Fluxes From Three Bioenergy Crop Candidates: How Energy Sorghum Compares To Maize And Miscanthus, Caitlin E. Moore, Adam C. Von Haden, Mark B. Burnham, Ilsa B. Kantola, Christy D. Gibson, Bethany J. Blakely, Evan C. Dracup, Michael D. Masters, Wendy H. Yang, Evan H. Delucia, Carl J. Bernacchi

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Perennial crops have been the focus of bioenergy research and development for their sustainability benefits associated with high soil carbon (C) and reduced nitrogen (N) requirements. However, perennial crops mature over several years and their sustainability benefits can be negated through land reversion. A photoperiod-sensitive energy sorghum (Sorghum bicolor) may provide an annual crop alternative more ecologically sustainable than maize (Zea mays) that can more easily integrate into crop rotations than perennials, such as miscanthus (Miscanthus × giganteus). This study presents an ecosystem-scale comparison of C, N, water and energy fluxes from energy sorghum, maize and miscanthus during a typical …

Interring The Immigration Rule Of Lenity, Patrick J. Glen

Nebraska Law Review

The immigration rule of lenity has haunted immigration jurisprudence since its initial iteration in 1947. But as with any spectral entity, its existence is more ephemeral than real. The rule was meant to be a tiebreaker of sorts: a canon that where a provision of the immigration laws was ambiguous, the courts should impose the more lenient construction. It has never, however, been the dispositive basis for a holding of the Supreme Court. Rather, to the extent it has been referenced, it has been trotted out only as a rhetorical device to sanction a decision reached on other grounds. Even …

Sulfur Anions: Comments Upon Structure, Charles A. Kingsbury

Department of Chemistry: Faculty Publications

This work emphasizes the need for solvent simulation as well as a counterion in calculations concerning anions, although optimization may be difficult. Solvent and counterion both play a large role in conformation of the ion. Part of the reason for the success of sulfur anions in chemical reactions may be the ability of sulfone oxygen(s) to coordinate with the counterion (usually lithium). The “solvent” partially dissociates lithium from the carbanion center.

Apparent Townsend’S X Black-Throated Green Warbler (Setophaga Townsendi X Virens) Hybrids In Kansas And Nebraska, Jon C. King, Terry Swope, Kevin Groeneweg, Pete Janzen, Mark A. Brogie

Nebraska Bird Review

The Townsend’s Warbler (Setophaga townsendi), Hermit Warbler (Setophaga occidentalis), Golden-cheeked Warbler (Setophaga chrysoparia), and Black-throated Green Warbler (Setophaga virens) are similar in appearance and vocalizations. Evaluation of mtDNA suggests that these four species diverged about 1 million years ago during the mid-Pleistocene (Lovette et al. 2010), at which time glaciation separated ancestral forms thus allowing for speciation (Morse and Poole 2020). Under the environmental conditions prevalent today, however, the breeding distribution of Townsend’s Warbler now overlaps to a limited extent with those of the Hermit and Black-throated Green Warblers, and hybridization occurs …

Cultivating Hops For Cone Production In Nebraska, Stacy A. Adams

Department of Agronomy and Horticulture: Faculty Publications

The hop cone is the primary product of agronomic value when growing Humulus lupulus L. (common hop). Cones are modified stem and leaf structures that protect the female flower cluster that forms chemical compounds important for flavoring beer and other uses. The majority of hops in the United States (~96%) is grown in the states of Washington, Oregon, and Idaho. Hops can be grown in very diverse climates, but it is the climatic consistency of the Pacific NW that provides product consistency and reasoning commercial hops production is prevalent in the region. Hops is a niche crop outside of the …

Toxicity Of Sodium Nitrite-Based Vertebrate Pesticides For European Starlings (Sturnus Vulgaris), Scott J. Werner, Shelagh T. Deliberto, Hailey E. Mclean, Katherine E. Horak, Kirt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

In the 21st century, invasive animals rank second only to habitat destruction as the greatest threat to global biodiversity. Socially-acceptable and cost-effective strategies are needed to reduce the negative economic and environmental impacts of invasive animals. We investigated the potential for sodium nitrite (SN; CAS 7632-00-0) to serve as an avian toxicant for European starlings (Sturnus vulgaris L.). We also assessed the non-target hazard of an experimental formulation of SN that is being developed as a toxicant for invasive wild pigs (Sus scrofa L.). In gavage experiments with European starlings, we identified a lowest observed adverse effect level …
