Perturbative Generalization Of Nonparaxial Ultrashort Tightly-Focused Elegant Laguerre–Gaussian Beams, Andrew M. Vikartofsky

Department of Physics and Astronomy: Dissertations, Theses, and Student Research

An analytical method for calculating the electromagnetic fields of a nonparaxial elegant Laguerre-Gaussian (eLG) vortex beam is presented for arbitrary pulse duration, spot size, and LG mode. This perturbative approach provides a numerically tractable model for the calculation of arbitrarily high radial and azimuthal LG modes in the nonparaxial regime, without requiring integral representations of the fields. A key feature of this perturbative model is its use of a Poisson-like frequency spectrum, which allows for the proper description of pulses of arbitrarily short duration. The time-domain representation of this model is presented as a non-recursive closed-form expression to any order …

The Ecological Niche Of Echinococcus Multilocularis In North America: Understanding Biotic And Abiotic Determinants Of Parasite Distribution With New Records In New Mexico And Maryland, United States, Sebastian Botero-Cañola, Altangerel Tsogtsaikhan Dursahinhan, Sara E. Rácz, Parker V. Lowe, John E. Ubelaker, Scott Lyell Gardner

Scott L. Gardner Publications

English abstract: Understanding the factors shaping the niche of parasites and its expression over geographical space and through time continues to be a modern scientific challenge with the results of research in this area directly influencing both theoretical and applied biology. This is especially important for proactive management of zoonotic parasites such as Echinococcus multilocularis, the etiologic agent of alveolar echinococcosis. Echinococcus multilocularis has a Holarctic distribution; with its geographic range and prevalence increasing recently in areas of the western Palearctic, while its distribution dynamics are poorly understood in the Nearctic. In this paper, we use an ecological niche …

Comparative Summary by Peter Roudik, Director of Legal Research

This report examines the legal approaches of fifteen countries, representing all regions of the world, to the emerging problem of manipulation with “fake news” using mass and social media, especially the impact of fake news on ongoing political processes and elections, and the legislative measures undertaken to counteract the dissemination of false information. Fake news as a phenomenon is not new and has been known since ancient times, but the present-day proliferation of digital and social media platforms, which allow for much broader distribution of information to a global audience, makes …

Regulation Of Vaccinia Virus Replication: A Story Of Viral Mimicry And A Novel Antagonistic Relationship Between Vaccinia Kinase And Pseudokinase, Annabel T. Olson

School of Biological Sciences: Dissertations, Theses, and Student Research

Poxviruses employ sophisticated signaling pathways that thwart cellular defense mechanisms and simultaneously ensure viral factors are modulated properly. Yet, our understanding of these complex signaling networks are incomplete. For example, the vaccinia B1 kinase plays a vital role in inactivating the cellular antiviral factor BAF, and is suggested to orchestrate other pathways. B1 is highly conserved among poxviruses and exhibits a remarkable degree of similarity to VRKs, a family of cellular kinases, suggesting that the viral enzyme has evolved to mimic VRK activity. Indeed, B1 and VRKs have been demonstrated to target a shared substrate, the DNA binding protein BAF, …

The Role Of Inflammatory Pathways In Development, Growth, And Metabolism Of Skeletal Muscle In Iugr Offspring: Blood Gene Expression Of Inflammatory Factors As Novel Biomarkers For Assessing Stress And Wellbeing In Exotic Species, Robert J. Posont

Department of Animal Science: Dissertations, Theses, and Student Research

Our first study identified the effects of maternal inflammation-induced intrauterine growth restriction (MI-IUGR) on growth and muscle glucose metabolism in offspring supplemented with curcumin. MI-IUGR lambs exhibited asymmetric growth restriction at birth and 30d of age, but normal glucose-stimulated insulin secretion. Hindlimb glucose oxidation was reduced by MI-IUGR and not improved by curcumin supplementation. Ex vivo muscle glucose oxidation was reduced by MI-IUGR but improved somewhat by curcumin. These finding indicate that fetal programming responses to MI contribute to neonatal growth and metabolic deficits. Neonatal curcumin supplementation had minimal effect on growth deficits but may improve glucose metabolism. …

Genome-Wide Association Studies In Maize And Sorghum, Preston Hurst

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Genome-wide association studies are used to identify genetic variants associated with a particular phenotype. GWAS has been used in a variety of taxa, from humans, to fish to plants . The present analysis is focused on two species important to the human species: maize and sorghum. A GWAS in maize was carried out on the modification of the Ga1-s allele. The Ga1 locus has long been studied as being involved in a unilateral crossing barrier . However, it has long been suspected that the locus is modified by background genetic factors . GWAS was used to observe candidates for this …

Examining The Capacity Of Nebraska Rangelands For Cattle Production And Evaluating Drought Management Strategies, Kaitlyn L. Cumming

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This thesis has two chapters focusing on the grazing capacity of Nebraska rangelands, and drought management strategies. The first chapter conducts a gap analysis comparing forage supplied by perennial grasslands to the animal unit months (AUMs) required by the cattle. The purpose of this research was to quantify potential AUM supply (i.e., carrying capacity) of grazing lands dominated by perennial grasses on a regional basis in Nebraska to the AUM demand based on cattle inventories and standard production practices in each region of Nebraska. The results suggest that Nebraska is operating at 100% of potential carrying capacity. Harvest efficiency for …

As a result of this study, three themes emerged regarding students’ learning experiences: Changes in Intercultural Development Inventory Assessment Results Indicated Positive Growth in Intercultural Competence, Intercultural Leadership Development Broadened Students’ Understanding of Culture and Leadership and Intercultural Leadership Development Requires Intentional Opportunities to Make Meaning. The corresponding subthemes helped clarify the learning experience of the participants, which aligned with the transformative intercultural learning model. In addition …

Crushing Caution, Lindsey Day

School of Art, Art History, and Design: Theses and Student Creative Work

I am preoccupied with the nuances of ordinary risk. I view this not as paranoia, but as prudence. To live without fear is a privilege, to be arrested by it is paralyzing. I often encounter two competing ideologies, two lenses, through which risk is evaluated. The first lens is for the victim, the person being crushed by, or blinded from, cautiousness. They see life as something happening to them, and avoid active risk-taking. The second lens is held by the person dominating apprehension, taking action in spite of consequence. I am inclined to find and maintain a balance of these …

Malleable Perspectives, Erik White

School of Art, Art History, and Design: Theses and Student Creative Work

I attentively paint hastily formed figures, symbols, objects, and scenes that were modeled with never-dry clay onto stretched canvases of various sizes. I paint the malleable character of the clay by depicting its bumps, marks and dents, which emphasizes the fragility, impermanence, and the physical construction of the forms. Those visual attributes serve as a metaphor for the social construction of the concepts within the chosen imagery. To create my images I build clay up and physically move it around—in a similar way, ideas and concepts get built up, manipulated, and changed over time. These paintings serve as a cultural …

Restorative, Mallory Trecaso

School of Art, Art History, and Design: Theses and Student Creative Work

The series of photographs in Restorative examines intimate views of home interiors that metaphorically embody my physical self. Emergency surgery left me with new marks, scars, and a patchwork of temporary solutions, and a heightened understanding of my own physicality. I use the familiar subject of the home to talk about my body. Looking through the lens of the home as a metaphor gives the viewer a different framework to view, rather confronting one’s self directly. Like a home, a body records time through markings, imperfections, discoloration, and cracks. Some, like a broken window or a scratch, happen suddenly while …

Development Of Nanomaterial Supports For The Study Of Affinity-Based Analytes Using Ultra-Thin Layer Chromatography, Allegra Pekarek

Department of Chemistry: Dissertations, Theses, and Student Research

Ultra-thin layer chromatography (UTLC) is a growing field in analytical separations. UTLC is a branch of planar and liquid chromatography that is related to thin layer chromatography. The main advantage of UTLC compared to other techniques is it uses much less material, allowing for faster and more sensitive separations to take place. The UTLC devices fabricated in this project used either silicon oxide or silicon nanopillars deposited on a glass slide using glancing angle deposition (GLAD). Even a thin layer of these nanopillars deposited on a glass slide provide a large surface area for the analyte to be separated. GLAD …

Peers Matter: Links Between Classmates’ And Individual Students’ Executive Functions In Elementary School, Jenna E. Finch, Elisa B. Garcia, Michael J. Sulik, Jelena Obradović

Department of Psychology: Faculty Publications

Students’ executive functions (EFs) are linked to school success. Although school-age children spend much of their time interacting with peers, few studies have explored how children’s classmates may promote EF development in elementary school. In this study, we test whether mean levels and variability in classmates’ EF skills are associated with growth in individual students’ accuracy and speed on EF tasks among third, fourth, and fifth graders (N = 806). We find that classmates’ speed, but not accuracy, on EF tasks is linked to significant improvements in individual students’ EFs over the school year. Classmates’ average EFs, as indexed by …

Lithic Analysis Of An Early Archaic Assemblage On The Great Plains: The Spring Creek Site (25ft31), Andrea Elizabeth Kruse

Department of Anthropology: Theses and Student Research

Early Archaic sites on the Great Plains are few in number and often little studied and poorly reported, as they are almost always found via salvage or compliance archaeology. Of those Early Archaic sites that have been studied, rarely has the recovered debitage been analyzed in detail nor have tools been fully evaluated for use-wear. This thesis describes the lithic assemblage from the Spring Creek (25FT31) site located in southwestern Nebraska. As one of two important early sites in the state, detailed lithic analysis will complement the thorough analysis of faunal remains conducted in the 2000s. This thesis presents the …

Norming In Administrative Law, Jonathan S. Masur, Eric A. Posner

Duke Law Journal

How do regulatory agencies decide how strictly to regulate an industry? They sometimes use cost-benefit analysis or claim to, but more often the standards they invoke are so vague as to be meaningless. This raises the question whether the agencies use an implicit standard or instead regulate in an ad hoc fashion. We argue that agencies frequently use an approach that we call “norming.” They survey the practices of firms in a regulated industry and choose a standard somewhere within the distribution of existing practices, often no higher than the median. Such a standard burdens only the firms whose practices …

Strange Bedfellows: Native American Tribes, Big Pharma, And The Legitimacy Of Their Alliance, Daniel C. Kennedy

Duke Law Journal

Lost in the cacophony surrounding the debate about high drug prices is the fundamental principle that pharmaceutical innovation will not occur without the prospect of outsized returns enabled through market exclusivity. Biopharmaceutical patents are currently under siege, subject to challenge both in inter partes review (“IPR”) proceedings and in Hatch-Waxman actions. These twin assaults threaten to eliminate the incentives necessary for biotechnological innovation—particularly for discoveries made upstream in the innovation pipeline—thus imperiling the development of new drug therapies. But a fascinating solution has emerged: invoking tribal immunity to shield pharmaceutical patents from IPR before the Patent Trial and Appeal Board …

Using Theoretical And Experimental Particle Packing For Aggregate Gradation Optimization To Reduce Cement Content In Pavement Concrete Mixtures, Miras Mamirov

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

The main objective of this study was to evaluate the effect of aggregate particle packing optimization and cement reduction on Nebraska slip-form pavement concrete performance. A literature review was conducted to examine different aggregate optimization tools, quality control tests, and historical data of Nebraska Department of Transportation (NDOT) mixtures. It was found that the Modified Toufar Model has good potential in optimizing particle packing and predicting packing degrees. The combined void content test was found to be useful to experimentally justify optimized aggregate gradations. Two specific pavement concrete workability tests, i.e., the Box Test and the VKelly Test, were used …

Proportion And Evaluation Of Ultra-High Performance Concrete Using Local Materials, Flavia Ribeiro Furtado De Mendonca

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Ultra-high performance concrete (UHPC) is a new class of concrete that has superior workability, as well as mechanical and durability properties that far exceed those of conventional concrete. To achieve these properties, a very dense internal structure and the very low water-to-binder ratio (w/b) generally are necessary. While particle packing models are typically used to design UHPC, due to the complexity of the composition interaction and characteristics of UHPC, these models might not necessarily provide the best design, which leads to the need of experimental study to justify UHPC performance. The evaluation of the impact of various design parameters on …

Department of Paediatrics and Child Health

Translating the Nurturing Care Framework and unprecedented global policy support for early child development (ECD) into action requires evidence-informed guidance about how to implement ECD programmes at national and regional scale. We completed a literature review and participatory mixed-method evaluation of projects in Saving Brains®, Grand Challenges Canada® funded ECD portfolio across 23 low- and middle-income countries (LMIC). Using an adapted programme cycle, findings from evaluation related to partnerships and leadership, situational analyses, and design for scaling ECD were considered. 39 projects (5 'Transition to Scale' and 34 'Seed') were evaluated. 63% were delivered through health and 84% focused on …

A Gis-Based Synthesis Of Relict Shorelines In Pennsular Florida, Justin O. Hardin

Ocean Engineering and Marine Sciences Student Publications

A literature review as well as a consultation with a geomorphologist, Dr. Christopher P. Williams, at the Florida Geological Survey (FGS) were both performed in order to understand the state of knowledge on relict shorelines in peninsular Florida. This knowledge was compiled into a map, Figure 1, that shows the locations and relative ages of geologically confirmed relict shorelines in the Florida peninsula. A number of additional required areas of research in order to “complete” the map are then discussed. The project highlights both the rapidity of Florida’s Pliocene-Pleistocene coastal evolution and the relatively high amount of incompleteness still present …

Evolving Narratives About College: Immigrant Community College Students’ Perceptions Of The Four-Year Degree In The Great Plains, Moises Padilla, Justin Chase Brown, Elvira Abrica

Department of Educational Administration: Faculty Publications

A significant percentage of the enrollment growth in higher education can be attributed to the recruitment of more diverse students, including those from immigrant households. Although research on immigrant students is growing in light of changing U.S. demographic shifts, this literature is inchoate. This paper examines evolving perspectives of the value of a four-year degree among immigrants and children of immigrants. Thus, in this paper article we synthesize current dominant narratives of immigrant students about the utility and viability of a four-year degree (and the changing impact on community college enrollment) and how they have shifted over time. We observe …

A Deep Learning Approach To Detect Diabetic Retinopathy In Fundus Images., Winston R. Furtado

Electronic Theses and Dissertations

Background: Diabetic retinopathy is a disease caused due by complications of diabetes mellitus which can lead to blindness. About 33% of the US population with diabetes also show symptoms for diabetes retinopathy. If not treated, diabetic retinopathy worsens over time by progressing through two main pathological stages of non-proliferative and proliferative and four clinical stages. While the diagnostic accuracy of detecting diabetic retinopathy through machine learning have shown to be successful for OCT images, the accuracy of ultra-widefield fundus images have yet to be fully reported. This paper describes a method to non-invasively detect and diagnose diabetic retinopathy from ultra-widefield …

Experimental Investigation Of The Manufacture Of Tunable Graphene Oxide Filter Membranes Using Intense Pulse Light, Joshua H Kotter

Electronic Theses and Dissertations

Reduced graphene oxide is a thin, strong, and inexpensive material with a channel and pore structure that make it a promising candidate for a filtration material. Reduced graphene oxide has been produced and tested in the laboratory, but a lack of scalable manufacturing techniques have limited its commercial use.

This thesis has shown that graphene oxide can be rapidly manufactured with an industrially scalable flash reduction process. The flash reduction process uses 0.58 millisecond pulses from a xenon lamp to reduce the graphene oxide film in less than a minute. Results for partially reduced graphene oxide membranes tuned by the …
