Controlling The Broadband Enhanced Light Chirality With L-Shaped Dielectric Metamaterials, Ufuk Kilic, Matthew Hilfiker, Shawn Wimer, Alexander Ruder, Eva Schubert, Mathias Schubert, Christos Argyropoulos

Department of Electrical and Computer Engineering: Faculty Publications

The inherently weak chiroptical responses of natural materials limit their usage for controlling and enhancing chiral light-matter interactions. Recently, several nanostructures with subwavelength scale dimensions were demonstrated, mainly due to the advent of nanofabrication technologies, as a potential alternative to efficiently enhance chirality. However, the intrinsic lossy nature of metals and the inherent narrowband response of dielectric planar thin films or metasurface structures pose severe limitations toward the practical realization of broadband and tailorable chiral systems. Here, we tackle these problems by designing all-dielectric silicon-based L-shaped optical metamaterials based on tilted nanopillars that exhibit broadband and enhanced chiroptical response in …

Mental Healthcare Differences Between The United States, Costa Rica, And Sweden, Michaela Diehm

Honors Program: Senior Projects (Public)

Countries such as the United States, Costa Rica, and Sweden differ in the ways that they approach treatment of mental health disorders, which is due to the structure of their healthcare as well as the culture, affordability, accessibility, and type of treatment that is available to the people of that country. A literature review did not reveal a comparison of the three countries related to the topic of mental healthcare, nor use of the three selected countries to review their structures to determine the best approach to combating mental disorders before. Costa Rica and Sweden are both countries with universal …

A Guide For The Breeding Of The Blue Death Feigning Beetle, Joe Maloney

Department of Entomology: Distance Master of Science Projects

Purpose

Asbolus verrucosus, often referred to as the Blue Death Feigning beetle (BDFB) is a species commonly exhibited by zoos, museums, and private individuals due to its beautiful blue color, long life, and fascinating death-feigning behavior. Despite being a very popular species, it is difficult to find specific information regarding breeding requirements and larval care. This is largely due to relatively little being known about the various stages of the BDFB life cycle. My intention in doing this project was to document verified information about the BDFB life cycle from reputable sources and use that information to develop a …

The Bloodless Period: A Transfeminine Experience, Rin Nguyen

College of Education and Human Sciences: Dissertations, Theses, and Student Research

There is limited research exploring menstruation in transgender and gender diverse (TGD) populations, and studies have primarily examined the relationship between menstruation and gender congruence. Findings revealed menstruating TGD people experienced distress related to decreased gender congruence (Eisenberg et al., 2021), and 88% of TGD people expressed interest in menstrual suppression to manage the distress (Schwartz et al., 2022). By contrast, Lowik (2020) highlighted a transfeminine person who wished to menstruate to achieve womanhood and commented on the “bloodless period” (i.e., menstrual-like symptoms in the absence of bleeding) upon receiving gender-affirming hormone therapy. To the author’s knowledge, there is no …

Hilling As A Management Tactic And Tool For Understanding Soybean Gall Midge (Resseliella Maxima Gagné), Pragya Gupta

Department of Entomology: Dissertations, Theses, and Student Research

Soybean gall midge (Resseliella maxima Gagné, SGM) emerged as a new species in the United States Midwest in 2019, causing injury to soybean (Glycine max L.) Infestation of R. maxima starts with females laying eggs in the fissures or cracks that develop at the base of soybean during the V2-V3 growth stage. The emerged larvae feed on the stem internally, leading to wilting and death of the plants. With knowledge gaps in biology and behavior, management strategies for this pest are challenging. Hilling is a cultural practice causing soil to cover the base of stems and is …

Between Pages And Politics: An Interdisciplinary Exploration Of Book Bans, Hannah Morrison

Department of English: Dissertations, Theses, and Student Research

Across the United States, school boards are being inundated with requests to ban books. While these conversations are often localized, what the rise in censorship across the country suggests is that there is a fierce movement behind censoring young adult literature. What is frequently erased in these campaigns are stories of people of color and queer communities, alongside topics such as sexuality, drugs, or violence. The presiding conclusion within childhood studies on how we have reached a point where censorship is abundantly common in American schools is that public discourse views children as less than or not fully formed, thus …

Discrete Macaulay-Steiner Geometry, Nikola Kuzmanovski

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This thesis is concerned with discrete isoperimetric inequalities and Hilbert functions. Two generalizations of the Ahlswede-Cai local global principle are presented. These results give positive answers to two questions posed by Harper. One of these results is achieved by proving uniqueness of the lexicographic and colexicographic orders in two dimensions. The other result generalizes the technique which is commonly known as compression and includes almost all previously published results in this direction. The Ahlswede-Cai local global principle is a direct corollary of this result. Optimal downsets are studied in rectangles and triangles. All optimal downsets are found. The main result …

"It's Profound To Be Understood": Negotiations Of Household Labor In Trans Families, Eliza Thor

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The gendered division of household labor has long been of interest to family scholars. For heterosexual couples, labor is often unequally divided, with women normatively taking on more labor than their partners. This inequality is often justified through time availability, resource dependency, and gender ideology. However, less studied is the division of household labor in relationships in which at least one partner is transgender or gender diverse (TGD). Drawing on the framework of “doing gender,” I explore how performing labor that aligns with traditional gender expectations affirms the gender identities of TGD individuals, making the division of labor in the …

Constructing Refugee Identity: A Heuristic Inquiry Into Experiences Of Ukrainian Refugees, Deana Tsabak

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Besides the despicable atrocities and devastation, Russia’s war in Ukraine caused the emergence of a group of refugees previously unknown in the U.S. and the world. The phenomenon of “Ukrainian refugees” is new to the immigration and resettlement agencies, host communities, employers, and educators. This research explores how five Ukrainians who left their homeland after the beginning of Russia’s war construct their refugee identity in the United States. Furthermore, this study aims to discover in what ways learning English in the English Language Learning (ELL) program at a community college in Nebraska influences refugee identity construction in resettlement.

Using Bandura’s (2000) collective efficacy theory, this study was guided by the following questions: (1) How does a campus police department use a community policing model to build partnerships with students, faculty, and staff? (2) How do police officers, students, faculty, and staff perceive these partnership-building efforts, particularly as it relates to fostering collective efficacy within the campus community? (3) Through what processes have campus police partnerships with students, faculty, and staff contributed …

Novel Insights Into The Autoimmune Mechanisms In Coxsackievirus B Infections And Their Prevention By Vaccination, Mahima Theresa Rasquinha

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Coxsackievirus Bs (CVBs) are RNA viruses of the genus Enterovirus belonging to the Picornaviridae family. CVBs commonly infect humans, and multiple CVB types can induce similar diseases such as myocarditis, pancreatitis, and type 1 diabetes (T1D). Although CVB infections can lead to the generation of autoantibodies, their role in disease is poorly defined, and vaccines are not available to prevent or minimize these infections. To fill these gaps, we first analyzed the autoantibody repertoire in mice infected with CVB3 by Phage ImmunoPrecipitation Sequencing (PhIP-Seq) and identified autoantibodies for several novel antigens not previously reported. The data were validated using enzyme-linked …

The Effect Of Sample Grinding On Color-Based Predictions Of Soil Organic Carbon, Mason Rutgers

Honors Program: Senior Projects (Public)

Measurements of soil color are widely accessible and can be used as indirect measures of soil organic carbon (SOC). Sensor-based soil color measurements, frequently used in quantitative studies to predict SOC, often use ground and sieved soil samples for color analysis. However, it is unknown whether the extra steps of drying, crushing, and sieving a sample improve the quantitative relationship between color and SOC. This study was conducted to evaluate color-based predictions of SOC using intact, sieved (<2 mm), and fine-ground soil samples from northwest Oklahoma. Moist soil color was measured using Munsell color charts (MCCs) and a Nix Mini 3™ portable color sensor (PCS). The color of the soil samples was measured before processing, after crushing to pass through a 2-mm sieve, and after mechanical grinding to less than 0.25-mm. Using Munsell value (from the MCC) and CIEL* (from the PCS) as predictor variables, regression analyses were conducted to develop SOC predictive functions for each physical state. The resulting coefficients of determination (R2) and root mean squared errors (RMSE) were used to assess model fits for predicting SOC. Model contrasts were calculated to evaluate significant differences between each predictive model. All models exhibited strong relationships (0.56 < R2 < 0.70, 0.20 < RMSE < 0.25) between soil lightness and predicted SOC. Models built using aggregated samples measured with both MCCs (R2= 0.70, RMSE= 0.20) and the PCS (R2= 0.69, RMSE= 0.21) produced the best results. Models built using intact samples measured using the PCS did perform significantly better on samples dark in color (CIEL* < 30). These results suggest that grinding soil samples does not improve color-based predictions of SOC using MCCs and the PCS.
