As funding agencies and publishers reiterate research data sharing expectations (1), many higher-education institutions have demonstrated their commitment to the long-term stewardship of research data by connecting researchers to local infrastructure, with dedicated staffing, that eases the burden of data sharing. Institutional repositories are an example of this investment (2). They provide support for researchers in sharing data that might otherwise be lost: data without a disciplinary repository, data from projects with limited funding, or data that are too large to sustainably store elsewhere. The staffing and technical infrastructure provided by institutional repositories ensures responsible access to information while considering …

Nebraska Rural Poll

Most rural Nebraskans believe the lack of civil or respectful discourse in our political system is either a very serious or a somewhat serious problem. The responses were fairly similar to those received last year.

In addition, most rural Nebraskans think Americans are more divided over politics than they were 10 years ago. The responses are similar to those received last year.

Despite that feeling, most rural Nebraskans have friends who have political views that are very different from their own. Yet, some rural Nebraskans are no longer able to talk to friends or family members because of their views …

Dirt/Μ: Automated Extraction Of Root Hair Traits Using Combinatorial Optimization, Peter Pietrzyk, Neen Phan-Udom, Chartinun Chutoe, Lise Pingault, Ankita Roy, Marc Libault, Patompong Johns Saengwilai, Alexander Bucksch

Department of Entomology: Faculty Publications

As with phenotyping of any microscopic appendages, such as cilia or antennae, phenotyping of root hairs has been a challenge due to their complex intersecting arrangements in two-dimensional images and the technical limitations of automated measurements. Digital Imaging of Root Traits at Microscale (DIRT/μ) is a newly developed algorithm that addresses this issue by computationally resolving intersections and extracting individual root hairs from two-dimensional microscopy images. This solution enables automatic and precise trait measurements of individual root hairs. DIRT/μ rigorously defines a set of rules to resolve intersecting root hairs and minimizes a newly designed cost function to combinatorically identify …

High-Mast Tower Foundation – Phase Ii, Ammar Al Maabreh, Abdelrahman Awawdeh, Marc Maguire, Jay Puckett, Brandon Kreiling

Nebraska Department of Transportation: Research Reports

Challenge: High-mast luminaire supports used in the US transportation sector are typically steel poles that are attached to a baseplate via a butt or socket weld. Many have failed primarily due to fatigue cracking at the weld toe. Significant research in the US improved the fatigue performance of these structures; however, failures still occur due to high-cycle cracking at the weld toes, or at other fatigue-prone details. Additionally, poles are failing in moderate winds that create galloping. Galloping is an aerodynamic phenomenon where the wind excitation frequency matches the pole’s natural frequency creating resonance. The top amplitudes are many times …

Natural Killer Cell Effector Function Is Critical For Host Defense Against Alcohol-Associated Bacterial Pneumonia, Daniel Villageliu, Kelly C. Cunningham, Deandra R. Smith, Daren L. Knoell, Mason Mandolfo, Todd A. Wyatt, Derrick R. Samuelson

Food for Health: Publications

Alcohol use is an independent risk factor for the development of bacterial pneumonia due, in part, to impaired mucus-facilitated clearance, macrophage phagocytosis, and recruitment of neutrophils. Alcohol consumption is also known to reduce peripheral natural killer (NK) cell numbers and compromise NK cell cytolytic activity, especially NK cells with a mature phenotype. However, the role of innate lymphocytes, such as NK cells during host defense against alcohol-associated bacterial pneumonia is essentially unknown. We have previously shown that indole supplementation mitigates increases in pulmonary bacterial burden and improves pulmonary NK cell recruitment in alcohol-fed mice, which were dependent on aryl hydrocarbon …

Technical Note: Assessing Gps Sensor Accuracy Using Real-Time Kinematic Device For Livestock Tracking, Biquan Zhao, Rebecca Mcdermott, Galen E. Erickson, Yijie Xiong

Department of Animal Science: Faculty Publications

The technical aspects of global positioning system (GPS) sensors have been improved substantially over the years, making them valuable and popular tools for livestock tracking. Using GPS sensors allows producers and researchers to locate grazing livestock, monitor their behavior and distribution, and gather referencing information about the health status of the animals and pastures. However, interpreting the behavior of grazing livestock, such as cattle, from GPS data can be difficult due to positioning inaccuracies. Without knowing the positioning accuracy range of GPS sensors, achieving high-level confidence in determining grazing densities and identifying abnormal livestock movement patterns is challenging. …

Amphiphala, A New Genus And Its Three New Species From Eastern North America (Lepidoptera: Tortricidae: Cochylina), Michael A. Roberts, Michael Sabourin, John W. Brown

Insecta Mundi

Amphiphala Roberts and Sabourin, new genus (Lepidoptera: Tortricidae), is proposed for three new species: A. liatriana Roberts and Sabourin, new species; A. landryana Brown, new species; and A. carolana Sabourin, new species. The genus is recorded from the eastern part of North America from Ontario, Canada south to South Carolina, and west to Manitoba and Mississippi. Owing to its superficial similarity to the banded sunflower moth, Cochylichroa hospes (Walsingham, 1884), Amphiphala remained hidden in North American Lepidoptera collections. Amphiphala liatriana has been reared from northern blazing star, Liatris scariosa (L.) Willd. (Asteraceae), in Maine.

Challenges In Assessing Repellency Via The Behavioral Response By The Global Pest Tribolium Castaneum To Protect Stored Grains, Leslie Catherine Rault, William R. Morrison Iii, Alison R. Gerken, Georgina Bingham

Department of Entomology: Faculty Publications

Background: Food security is an increasingly pressing global issue, and by 2050, food production will not be sufficient to feed the growing population. Part of global food insecurity can be attributed to post-harvest losses, including quantity and quality losses caused by stored-product pests like insects. It is thus timely to find management strategies to mitigate these losses and counteract food insecurity. The red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), a global stored-product pest with a wide range of food sources, was used in this study to assess repellency to a selection of essential oils. Methods: Multiple behaviorally relevant methods …

This project aims to build a robust groundwater model to evaluate optimal scenarios for sustainable use of the groundwater resource within a section of the Ogallala aquifer located in the Middle Republican Natural Resources District (MRNRD). This study follows a comprehensive approach involving parameterization, construction, and optimization. The model is parametrized using hydraulic conductivity and recharge values obtained from a random forest-based machine learning …

Molecular Detection Of Pathogenic Bacteria In American Dog Ticks (Dermacentor Variabilis) In Brown County, Nebraska, Nicole Messbarger, Darby Carlson, Keith Geluso, Julie Shaffer

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Ticks carry and transmit disease pathogens that cause many human illnesses. Many of these diseases in humans are accompanied by a wide variety of symptoms making tick-borne illnesses often difficult to diagnose. The rate of reported tick-borne illnesses in humans has increased during the past decades in the United States, alongside a rise in concern for public health and safety. In northern Nebraska, the American dog tick (Dermacentor variabilis) is the primary tick encountered by humans and domestic animals in the region. This species is a known vector for spotted fever group (SFG) rickettsioses and tularemia (Francisella …

The Feasibility Of Utilizing The Open Dynamic Interaction Network (Odin) App To Assess Rema Data Across 30 Days Among Those Recovering From Alcoholism, Dennis E. Mcchargue, Bilal Khan, Jesscia Phelps, Patrick Duryea, Kimberly A. Tyler, Arthur Andrews, Ellie Reznicek, Lucy Napper, Mohamed Saad, Hsuan-Wee Lee

Department of Psychology: Faculty Publications

About ~4 million people with an alcohol use disorder receive treatment annually, and frequent relapse has produced a rapid revolving door between recovery and use. This paper presents preliminary data from a prospective micro-longitudinal study (30 days) that examines co-evolution of relapse risk processes of people with alcohol use disorders who entered a short-term residential substance use treatment. The primary goal of the current data was to assess the feasibility of using the open dynamic interaction network (ODIN) responsive ecological momentary assessment (rEMA). rEMA collected daily estimates on affect, urges, sober-support engagement, and use. The ODIN app administered twelve questions …

Development Of A Multidimensional Measure Of Wellbeing For Emerging Adults Utilizing A Convergent Parallel Mixed Method Design, Kelley Marie Wick

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

Attempting to conceptualize wellbeing is difficult, and the current research literature does not offer a standard definition that encapsulates the complexity of this construct, nor has there been a thorough consideration the impact of culture and societal standards of behavior on wellbeing. Additionally, the emergence of a new developmental period between adolescence and true adulthood (emerging adulthood) offers an additional layer of nuance, as many of the traditional scales currently used to measure wellbeing are inappropriate for emerging adults. A major gap in the current research literature is the reluctance in developing measures with the help of the target population. …

Conservation Decision Making And Agricultural Land Leasing - An Experimental Investigation Of The Role Of Gender, Diya Ganguly, Simanti Banerjee, Christopher Gustafson

Cornhusker Economics

This research investigated the impact of landowner gender and of the different types of contract leases offered by them to a male tenant, on the conservation (or non-conservation) choice made by the tenant. Specifically, we investigate if a) female and male landowners offer different rental contracts and b) whether tenants choose different actions based on the landowner’s gender. For this purpose, we implemented a controlled, gender-context-loaded economic experiment with university students, in which we tested contract and land use choice under different treatments for three types of rental contracts – fixed rent, fixed rent with penalty, and fixed rent with …

Fourier Transform Ion Cyclotron Resonance Mass Spectrometry Applications For Metabolomics, Darcy Cochran, Robert Powers

Robert Powers Publications

Metabolomics is an interdisciplinary field that aims to study all metabolites < 1500 Da that are ubiquitously found within all organisms. Metabolomics is experiencing exponential growth and commonly relies on high-resolution mass spectrometry (HRMS). Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) is a form of HRMS that is particularly well suited for metabolomics research due to its exceptionally high resolution (10⁵–10⁶) and sensitivity with a mass accuracy in parts per billion (ppb). In this regard, FT-ICR-MS can provide valuable insights into the metabolomics analysis of complex biological systems due to unique capabilities such as the easy separation of isobaric and isomeric species, isotopic fine structure analysis, spatial resolution of metabolites in cells and tissues, and a high confidence (error) in metabolite identification. Alternatively, the large and complex data sets, long acquisition times, high cost, and limited access mainly through national mass spectrometry facilities may impede the …

Immunological Feedback Loops Generate Parasite Persistence Thresholds That Explain Variation In Infection Duration, Clayton E. Cressler, Daniel C.G. Metz, David A. Chang Van Oordt, Andrea L. Graham

School of Biological Sciences: Faculty Publications

Infection duration affects individual host fitness and between-host transmission. Whether an infection is cleared or becomes chronic depends on the complex interaction between host immune responses and parasite growth. Empirical and theoretical studies have suggested that there are critical thresholds of parasite dose that can determine clearance versus chronicity, driven by the ability of the parasite to manipulate host immunity. However, the mammalian immune response is characterized by strong positive and negative feedback loops that could generate duration thresholds even in the absence of direct immunomodulation. Here, we derive and analyse a simple model for the interaction between T-cell subpopulations …

Homocopris Burmeister, 1846 (Coleoptera: Scarabaeidae): Lectotype Designation For Copris Torulosus Eschscholtz, 1822, And Correction On The Geographic Distribution Of The Two Chilean Species, José Mondaca, Fernando Z. Vaz-De-Mello

Insecta Mundi

Homocopris Burmeister, 1846 (Coleoptera: Scarabaeidae) is a small genus of South American dung beetles composed of four species distributed in Argentina, Brazil, and Chile. Recently, a neotype was designated for Copris torulosus Eschscholtz, 1822 (currently H. torulosus) based on the assumption that the original type series had been lost. However, this designation is invalid for failing to comply with articles 75.2, 75.3, 75.3.1, and 75.3.4. of the International Code of Zoological Nomenclature. Furthermore, even if it had been nomenclaturally valid, the neotype now loses its type status because we found a syntype in the material of the Johann …

Nebraska Rural Poll

This year, rural Nebraskans are more pessimistic about their current situation than they’ve been since this study began. The proportion believing they are worse off than they were five years ago was 33 percent, up from 27 percent last year and 21 percent in 2022. This is the highest level across all years of the study. This increase in pessimism was matched with a sharp decrease in optimism. This year, just over one-third (36%) of rural Nebraskans believe they are better off compared to five years ago, down from 45 percent last year.

This trend continued when looking to the …
