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 …

“It Didn’T Hurt Me”: Patients’ And Providers’ Perspectives On Unsupervised Take‑Home Doses, Drug Diversion, And Overdose Risks In The Provision Of Medication For Opioid Use Disorder During Covid‑19 In San Juan, Puerto Rico, Roberto Abadie, Celia B. Fisher

School of Global Integrative Studies: Faculty Publications

Background During the COVID−19 pandemic, clinics offering medication for opioid use disorder (MOUD) needed to rapidly introduce unsupervised take−home dosing, while relapsing patients and patients unable to enter treatment faced increased risks of fentanyl−related overdose deaths and other drug−related harms. Based on a qualitative study of people who inject drugs (PWID) receiving MOUD treatment and MOUD staff in Puerto Rico, this paper documents the lived experiences of patients and providers during this period and the risk perceptions and management strategies to address substance misuse and drug diversion attributable to unsupervised take−home−dose delivery

Assessment Of Satellite-Based Water Requirements For A Drip-Irrigated Apple Orchard In Mediterranean Agroclimatic Conditions, Daniel De La Fuente-Saiz, Samuel Ortega-Farias, Marcos Carrasco-Benavides, Samuel Ortega-Salazar, Fei Tian, Sufen Wang, Yi Liu

Department of Civil and Environmental Engineering: Faculty Publications

Accurate assessment of evapotranspiration (ETa) and crop coefficient (Kc) is crucial for optimizing irrigation practices in water-scarce regions. While satellite-based surface energy balance models offer a promising solution, their application to sparse canopies like apple orchards requires specific validation. This study investigated the spatial and temporal dynamics of ETa and Kc in a drip-irrigated ‘Pink Lady’ apple orchard under Mediterranean conditions over three growing seasons (2012/13, 2013/14, 2014/15). The METRIC model, incorporating calibrated sub-models for leaf area index (LAI), surface roughness (Z_om), and soil heat flux (G), was employed to estimate ETa and Kc. These estimates were validated …

A sanitary challenge was carried out to induce suboptimal herd health while investigating the effect of amino acids supplementation on piglet responses. Weaned piglets of high sanitary status (6.33 ± 0.91 kg of BW) were distributed in a 2 × 2 factorial arrangement into two similar facilities with contrasting sanitary conditions and two different diets. Our results suggest that increased Trp, Thr, and Met dietary supplementation could support the immune systems of piglets under a sanitary challenge. In this manner, AA+ supplementation improved the performance and metabolism of piglets under mixed management and poor sanitary conditions. No major temporal microbiome …

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 …

Predicting The Potential Distribution Of Pseudococcus Longispinus (Targioni-Tozzetti) (Hemiptera: Pseudococcidae) In South Korea Using A Climex Model, Su Bin Kim, Soo-Jung Suh

Insecta Mundi

Pseudococcus longispinus (Targioni-Tozzetti) (Hemiptera: Pseudococcidae) is a widely-distributed pest that feeds on many economically important hosts, particularly tropical fruits and ornamentals. The potential distribution of this mealybug pest in South Korea remains a primary concern because of its high incidence of interceptions screened during inspection. Hence, this species prompted a modelling effort to assess its potential risk of introduction. Potential risk maps were developed for this pest with a CLIMEX model based on occurrence records under environmental data. The potential distribution of these pests in South Korea in the 2020s, 2050s and 2090s was projected based on the RCP 8.5 …

Department of Agronomy and Horticulture: Faculty Publications

Soil health is pivotal to agricultural sustainability. Promoting and sustaining soil health management is challenging since it involves many interdependent components and steps and is an iterative process. Herein, the soil health cycle (SHC) is proposed as a soil health management cycle encompassing human dimensions, management practices, and their effects on soil health indicators (SHIs), leading to subsequent impacts on soil functions. The SHC provides a structure for an iterative testing of changes to improve soil health. A systematic review of research publications was also conducted using the Web of Science database supplemented by Elicit AI and Scopus API searches …

Sex Differences And Sex‑Specific Regulation Of Motivated Behavior By Melanin‑Concentrating Hormone: A Short Review, Isabel R. K. Kuebler, Mauricio Suárez, Ken T. Wakabayashi

Department of Psychology: Faculty Publications

Recent preclinical research exploring how neuropeptide transmitter systems regulate motivated behavior reveal the increasing importance of sex as a critical biological variable. Neuropeptide systems and their central circuits both contribute to sex differences in a range of motivated behaviors and regulate sex-specific behaviors. In this short review, we explore the current research of how sex as a biological variable influences several distinct motivated behaviors that are modulated by the melanin-concentrating hormone (MCH) neuropeptide system. First, we review how MCH regulates feeding behavior within the context of energy homeostasis differently between male and female rodents. Then, we focus on MCH’s role …

Women’S Communities And Landscapes In Deadwood, South Dakota In The 1870s–1880s, Jessica Kaye Long

Department of Geography: Dissertations, Theses, and Student Research

This research focuses on the lives, experiences, and contributions of Deadwood women from 1875 to 1889. This range represents a defining period in Deadwood’s history stretching from its inception to the arrival of the railroad. Through this research, I seek to better understand the women living in a relatively isolated city during the gold rush. While previous research has focused on the city’s most famous women and sex workers of the Badlands, the lives of average citizens have been neglected. This research does not want to ignore the impacts of famous women or sex workers. Instead, this thesis attempts to …

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 …

Characterizing And Developing Chemistry Students’ Data Analysis And Interpretation Of Chemical Data, Stephanie A. Berg

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

All chemistry students must develop competency in analyzing and making sense of data. However, there are many difficulties that chemistry students may experience while analyzing data. Many students may not use relevant prior knowledge to aid in making sense of data, or they may not form conclusions using all the data provided. Additionally, prior knowledge seems to influence one’s data analysis, but little is known about how students use it to make sense of data. Thus, I interviewed undergraduate students as they analyzed graphical data for a task and characterized how they used their prior knowledge throughout. My findings suggest …

Las Aztecas: Gender, Nationalism, And Sport In Mexico And The World In The Early 1970s, Madelina Marie Homberger Cordia

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

In 1970, a Mexican women’s national fútbol (soccer) team participated in the first-ever women’s World Cup, held in Italy. Organized by private business interests, Mexico competed as the sole representative from outside of Europe. The Mexican media and State officials, such as Mexico City regent Alfonso Corona del Rosal, used this opportunity to frame the team’s travel abroad as defending not only the honor of the Mexican nation, but the entire Western Hemisphere against more developed and wealthier European teams. The following year, in 1971, Mexico hosted the second women’s World Cup and, in the same way that the State …

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 …
