Community and Regional Planning Program: Professional Projects

To assist the city of Concord in achieving its housing goals as presented in its general plan, while still meeting the stormwater discharge requirements laid out in the city’s municipal discharge permit, I worked with local developers and consultants to create a spreadsheet modeling tool that allows housing developers to estimate the total cost of green stormwater infrastructure needed to comply with local regulations.

This report contains a summary of the conditions leading to the necessity of this tool, the steps the tool takes that go beyond existing models, a description of how the model operates, instructions on how to …

The Early Years Of The Nebraska Ornithologists’ Union: People And Publications, Daniel W. Leger

Nebraska Bird Review

Nebraska once boasted that it had the greatest avian biodiversity of any state. Today, such a claim seems preposterous, but when it was made, back in 1899, it was serious. The antecedents of that claim underlie the objective of this article, namely to describe the early history of the Nebraska Ornithologists’ Union (NOU), its founding members, and its publications, one of which, the Nebraska Bird Review, you are reading today.

. . .

To say that many changes have occurred in ornithology and birding since the NOU started in 1899 would be a severe understatement. Most of these changes have …

Spring Field Report, March–May 2024, W. Ross Silcock

Nebraska Bird Review

A major concern this spring was the widely lamented shortfall in numbers of migrant warblers and the shortened duration of the migration, with most sightings relatively early. Numbers of migrant warblers east of the 100th meridian were investigated by Joel Jorgensen and Stephen Brenner and the scarcity was indeed found to be supported by eBird data; see the “News and Updates” section in Birds of Nebraska-Online (BONO). At Oliver Reservoir in the Panhandle, however, Steven Mlodinow found that migration was at least normal for a range of common migrants, with some migrants above the levels of the last four years. …

Neuropsychological Intra-Individual Variability In Traumatic Brain Injury: Clinical Utility, Classification, And Associations With Outcomes, Jeremy A. Feiger

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

Traumatic brain injury (TBI) survivors experience a range of sequelae including neurobiological brain changes, cognitive impairment, psychological difficulties, and functional changes. Neuropsychological assessment after injury is used to characterize current strengths and weaknesses to inform prognosis and interventions. There is currently no reliable and consistent method of assessing and classifying injuries in the post-acute and chronic phases of moderate to severe TBI (msTBI) that is associated with long term psychosocial outcomes. This study aimed to combine the use of within-person variability on neuropsychological test batteries and in cognitive response latency, known as intra-individual variability (IIV), with a novel cognitive phenotyping …

A Mixed Method Examination Of Bipositivity As A Factor Protecting Cis, Trans, And Gender Expansive Plurisexual Women Against Harmful Sexual Violence Outcomes, Allison E. Cipriano

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

Plurisexual women are more likely to experience sexual violence, post-traumatic stress (PTS), and alcohol use problems compared to women with single gender attraction. Disproportionately high rates of sexual violence may partially explain the prevalence of PTS and alcohol problems experienced by plurisexual women. Yet, research on sexual violence, PTS, and alcohol use problems have rarely specifically investigated these phenomena among plurisexual women. Researchers have identified a positive association between binegative experiences and risk of sexual violence among plurisexual women, suggesting that sexuality-based experiences may be connected to sexual violence victimization for this population. While identifying factors predicting risk of sexual …

The Mental Health Experience Of Transgender And Gender Diverse Colombians: Que La Diversidad No Cueste La Vida, María Natalia Acosta Canchila

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

Experiences of TGD people in various countries reflect difficulties accessing mental health services and significant mental health needs. In Colombia, experiences in broader healthcare systems suggest various barriers to care that include experiences of discrimination. However, specific experiences in mental health services have not been thoroughly examined. The current study aimed to understand the experiences, perceptions, and needs of TGD people in Colombia in mental health systems. Qualitative data was collected via 40 semi-structured interviews with TGD people in Colombia, data was analyzed via reflexive thematic analysis.

Modeling And Design Parameter Optimization To Improve The Sensitivity Of A Bimorph Polysilicon-Based Mems Sensor For Helium Detection, Sulaiman Mohaidat, F. M. Alsaleem

Durham School of Architectural Engineering and Construction: Faculty Publications

Helium is integral in several industries, including nuclear waste management and semiconductors. Thus, developing a sensing method for detecting helium is essential to ensure the proper operation of such facilities. Several approaches can be used for helium detection, including based on the high thermal conductivity of helium, which is several times higher than air. This work utilizes the high thermal conductivity of helium to design and analyze a bimorph MEMS sensor for helium sensing applications. COMSOL Multiphysics software (version 6.2) is used to carry out this investigation. The sensor is constructed from poly-silicon and SiO₂ materials with a trenched …

Harassment, Stalking, And Violence On Campus: An Examination Of Persistent Cases, Madeline M. Eyer

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

Stalking, harassment, dating violence, physical assault, and sexual assault continue to occur at elevated frequencies on college campuses. Most subjects cease engagement in these behaviors within a short period; however, a subset of individuals will engage in these intrusive behaviors over an extended length of time. While persistence has been examined in the stalking literature, only one study has examined risk factors of persistence in a college sample, and no studies have examined persistence for adverse behaviors outside of stalking (i.e., harassment, dating violence, physical assault, and sexual assault). Given the risk for physical and psychological harm toward targets as …

An Inaugural Forum On Epidemiological Modeling For Public Health Stakeholders In Arizona, Joseph R. Mihalijevic, Carmenlita Chief, Mehreen Malik, Kayode Oshinubi, Eck Doerry, Esma Gel, Crystal Hepp, Tim Lant, Sanjay Mehrotra, Samantha Sabo

Department of Supply Chain Management and Analytics: Faculty Publications

Epidemiological models—which help us understand and forecast the spread of infectious disease—can be valuable tools for public health. However, barriers exist that can make it difficult to employ epidemiological models routinely within the repertoire of public health planning. These barriers include technical challenges associated with constructing the models, challenges in obtaining appropriate data for model parameterization, and problems with clear communication of modeling outputs and uncertainty. To learn about the unique barriers and opportunities within the state of Arizona, we gathered a diverse set of 48 public health stakeholders for a day-and-a-half forum. Our research group was motivated specifically by …

Morphometric Analysis And Taxonomic Re-Evaluation Of Pepsis Cerberus Lucas And P. Elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae: Pepsini), Frank E. Kurczewski, Akira Shimizu, Diane H. Kiernan

Insecta Mundi

Hurd (1952) separated Pepsis cerberus Lucas from P. elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae: Pepsini) based on external morphology and biogeography. Vardy (2005) synonymized the familiar and historically well-documented P. cerberus and P. elegans, combining these Nearctic taxa with several Neotropical variants in an extremely broad definition of P. menechma Lepeletier. In doing so, Vardy (2005) breached the principle of nomenclatural stability. He ignored the prevailing usage and clearly violated articles 23.2, 23.3 and 23.9.1.2 of the ICZN (1999). Morphological differences, ecological divergence, and narrow sympatric geographic distribution of P. cerberus and P. elegans …

A New Species Of Paranthrene Hübner (Lepidoptera: Sesiidae) From The Northern Midwest United States, William H. Smith Iii, William H. Taft Jr., Anthony I. Cognato

Insecta Mundi

A clearwing moth species, Paranthrene sogaardi Taft and Smith, 2024, new species, is described from Michigan and Minnesota. The recognition of this new species is based on a phylogeny estimated from mitochondrial cytochrome oxidase I and wingless DNA sequences of 25 specimens representing all Paranthrene Hübner species including individuals from various locations. Paranthrene sogaardi new species was monophyletic and differed from Paranthrene tabaniformis Rottenburg, 1775 by a mean of 7.6% COI pairwise “p” distance, coloration, and genitalic morphology.

Internet-Based Data Platforms Re-Define The Distributions Of Some Large Crabronid Wasps In Arkansas (Hymenoptera: Crabronidae), David E. Bowles

Insecta Mundi

The geographic distributions of three large wasps, Sphecius speciosus (Drury), Stictia carolina Fabricius, and Stizus brevipennis Walsh (Hymenoptera: Crabronidae), occurring in Arkansas are defined using museum specimens and three internet-based data platforms. The internet-based data platforms generally provided more county location records than museum records. Using data from internet sources for easily identified species can better serve to illustrate the known distributions for some species thus making for a powerful tool elucidating distributional patterns and conservation planning.

Effect Of Antioxidant Additives And Recycling Agents On Performance Of Asphalt Binders And Mixtures, Phase I, Nitish R. Bastola, Mahdieh Khedmati, Hamzeh Haghshenas, Jamilla Teixeira

Nebraska Department of Transportation: Research Reports

The use of reclaimed asphalt pavement (RAP) in asphalt mixtures has notably increased in recent times. Nevertheless, the inherent stiff and aged characteristics of RAP materials have consistently raised concerns regarding cracking performance. The use of recycling agents (RAs) has gained popularity in recent years since they can effectively modify the engineering properties of the aged asphalt binder. Besides that, the combination of RA with antioxidant (AO) additives has shown promise in enhancing the long-term performance of RAP mixtures. This research aims to investigate the effect of various RAs and one AO additive on performance of asphalt binders and high-RAP …

Development Of The Nebraska Department Of Transportation Winter Severity Index – Phase Ii, Mark Anderson, Curtis L. Walker, Thomas Kauzlarich

Nebraska Department of Transportation: Research Reports

For the Nebraska Department of Transportation (NDOT), the Nebraska Winter Severity Index (NEWINS) provided an independent framework to calculate a winter season’s severity by categorizing individual winter storms. However, one of the greatest limitations of NEWINS is that it is not predictive. Thus, this study builds on the previously developed NEWINS by creating a predictive winter storm severity index known as NEWINS-Predictive (NEWINS-P). The quantitative precipitation forecast, snow accumulation, ice accumulation, and surface wind speed parameters from the National Digital Forecast Database (NDFD) are used to develop the five components composing the NEWINS-P framework. These components consist of snow severity …

Nonlinear Classifiers For Wet-Neuromorphic Computing Using Gene Regulatory Neural Network, Adrian Ratwatte, Samitha Somathilaka, Sasitharan Balasubramaniam, Assaf A. Gilad

School of Computing: Faculty Publications

The gene regulatory network (GRN) of biological cells governs a number of key functionalities that enable them to adapt and survive through different environmental conditions. Close observation of the GRN shows that the structure and operational principles resemble an artificial neural network (ANN), which can pave the way for the development of wet-neuromorphic computing systems. Genes are integrated into gene-perceptrons with transcription factors (TFs) as input, where the TF concentration relative to half-maximal RNA concentration and gene product copy number influences transcription and translation via weighted multiplication before undergoing a nonlinear activation function. This process yields protein concentration as the …

What Climate Change Means For Nebraska

United States Environmental Protection Agency: Publications

Nebraska’s climate is changing. In the past century, most of the state has warmed by at least one degree (F). The soil is becoming drier, and rainstorms are becoming more intense. In the coming decades, flooding is likely to increase, yet summers are likely to become increasingly hot and dry, which would reduce yields of some crops, require farmers to use more water, and amplify some risks to human health.

Our climate is changing because the earth is warming. People have increased the amount of carbon dioxide in the air by 40 percent since the late 1700s. Other heat-trapping greenhouse …

Measurement Of Simplified Template Cross Sections Of The Higgs Boson Produced In Association With W Or Z Bosons In The H → B[] Decay Channel In Proton-Proton Collisions At √S =13 Tev, A. Tumasyan

Kenneth Bloom Publications

Differential cross sections are measured for the standard model Higgs boson produced in association with vector bosons (W, Z) and decaying to a pair of b quarks. Measurements are performed within the framework of the simplified template cross sections. The analysis relies on the leptonic decays of the W and Z bosons, resulting in final states with 0, 1, or 2 electrons or muons. The Higgs boson candidates are either reconstructed from pairs of resolved b-tagged jets, or from single large-radius jets containing the particles arising from two b quarks. Proton-proton collision data at √s = …

Mitigating Identity-Related Anxiety Through Humor And Immersive Storytelling With 360-Degree Video In Virtual Reality: A Study On Microaggressions’ Mental Health Effects, Changmin Yan, Alan Eno, Adam Wagler

College of Journalism and Mass Communications: Faculty Publications

Background: Microaggressions are subtle slights that can cause significant psychological distress among marginalized groups. Few studies have explored interventions that might mitigate these effects. Objective: This study aimed to investigate if and how humor-infused immersive storytelling via virtual reality (VR) could reduce identity-related psychological distress caused by microaggressions. Methods: Using a community-based participatory research approach, we developed a 7-min 360-degree VR film depicting scenarios of microaggressions across various identities. Fortysix college students participated in a controlled study where they were exposed to this immersive VR experience. We measured identity-related psychological anxiety, character identification, perceived humor, and perceived …

Adaptation To Tolerate High Doses Of Arabinoxylan Is Associated With Fecal Levels Of Bifidobacterium Longum, Edward C. Deehan, Zhengxiao Zhang, Nguyen K. Nguyen, Maria Elisa Perez-Muñoz, Janis Cole, Alessandra Riva, David Berry, Carla M. Prado, Jens Walter

Department of Food Science and Technology: Faculty Publications

Dietary fiber supplements are a strategy to close the ‘fiber gap’ and induce targeted modulations of the gut microbiota. However, higher doses of fiber supplements cause gastrointestinal (GI) symptoms that differ among individuals. What determines these inter-individual differences is insufficiently understood. Here we analyzed findings from a six-week randomized controlled trial that evaluated GI symptoms to corn bran arabinoxylan (AX; n = 15) relative to non-fermentable microcrystalline cellulose (MCC; n = 16) at efficacious supplement doses of 25 g/day (females) or 35 g/day (males) in adults with excess weight. Self-reported flatulence, bloating, and stomach aches were evaluated weekly. Bacterial taxa …

Bagging Improves The Performance Of Deep Learning-Based Semantic Segmentation With Limited Labeled Images: A Case Study Of Crop Segmentation For High-Throughput Plant Phenotyping, Yinglun Zhan, Yuzhen Zhou, Geng Bai, Yufeng Ge

Department of Statistics: Faculty Publications

Advancements in imaging, computer vision, and automation have revolutionized various fields, including field-based high-throughput plant phenotyping (FHTPP). This integration allows for the rapid and accurate measurement of plant traits. Deep Convolutional Neural Networks (DCNNs) have emerged as a powerful tool in FHTPP, particularly in crop segmentation—identifying crops from the background—crucial for trait analysis. However, the effectiveness of DCNNs often hinges on the availability of large, labeled datasets, which poses a challenge due to the high cost of labeling. In this study, a deep learning with bagging approach is introduced to enhance crop segmentation using high-resolution RGB images, tested on the …
