A Stacking-Based Misbehavior Detection System In Vehicular Communication Networks, Troy Green

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Over the past few decades communication systems for vehicles have continued to advance. Communications between these vehicles can be classified into safety related and non safety related messages. An example of a safety related message would be one vehicle warning others of an icy road it encountered, where a non safety related communication would be a passenger streaming a movie. In either case it's important to secure the communications so that the system continues to behave as expected. In this thesis we propose a Misbehavior Detection System (MDS), which is a system that monitors messages sent between vehicles, and detects …

Low Power Multi-Channel Interface For Charge Based Tactile Sensors, Samuel Hansen

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Analog front end electronics are designed in 65 nm CMOS technology to process charge pulses arriving from a tactile sensor array. This is accomplished through the use of charge sensitive amplifiers and discrete time filters with tunable clock signals located in each of the analog front ends. Sensors were emulated using Gaussian pulses during simulation. The digital side of the system uses SAR (successive approximation register) ADCs for sampling of the processed sensor signals.

Department of Agronomy and Horticulture: Faculty Publications

Background: Pathogens have evolved diverse lifestyles and adopted pivotal new roles in both natural ecosystems and human environments. However, the molecular mechanisms underlying their adaptation to new lifestyles are obscure. Comparative genomics was adopted to determine distinct strategies of plant ascomycete fungal pathogens with different lifestyles and to elucidate their distinctive virulence strategies. Results: We found that plant ascomycete biotrophs exhibited lower gene gain and loss events and loss of CAZyme-encoding genes involved in plant cell wall degradation and biosynthesis gene clusters for the production of secondary metabolites in the genome. Comparison with the candidate effectome detected distinctive variations between …

Comparative Genomics Of Five Valsa Species Gives Insights On Their Pathogenicity Evolution, Guangchao Sun, Shichang Xie, Lin Tang, Chao Zhao, Mian Zhang, Lili Huang

Department of Agronomy and Horticulture: Faculty Publications

Valsa is a genus of ascomycetes within the Valsaceae family. This family includes many wood destructive pathogens such as the well known Valsa mali and Valsa pyri which cause canker diseases in fruit trees and threaten the global fruit production. Lack of genomic information of this family is impeding our understandings about their evolution and genetic basis of their pathogenicity divergence. Here, we report genome assemblies of Valsa malicola, Valsa persoonii, and Valsa sordida which represent close relatives of Valsa mali and Valsa pyri with different host preferences. Comparative genomics analysis revealed that segmental rearrangements, inversions, and translocations …

Importance Of Good Communications For Generational Ag Business Transfers, Allan Vyhnalek

Cornhusker Economics

Adapted from Right Risk, volume 10, Issue 10, October 2022.

Effective communication within a farm or ranch family, especially when multiple generations are operating and managing the business, is the underpinning of all other decisions made in a family business. It is critical that farm and ranch families identify areas of contention and develop communication skills that will allow them to negotiate satisfying outcomes. This may involve basic skills training, including communication, problem solving, and decision making.

Room-Temperature Polariton Quantum Fluids In Halide Perovskites, Kai Peng, Renjie Tao, Louis Haeberlé, Quanwei Li, Dafei Jin, Graham R. Fleming, Stéphane Kéna-Cohen, Xiang Zhang, Wei Bao

School of Computing: Faculty Publications

Quantum fluids exhibit quantum mechanical effects at the macroscopic level, which contrast strongly with classical fluids. Gain-dissipative solid-state exciton-polaritons systems are promising emulation platforms for complex quantum fluid studies at elevated temperatures. Recently, halide perovskite polariton systems have emerged as materials with distinctive advantages over other room-temperature systems for future studies of topological physics, non-Abelian gauge fields, and spin-orbit interactions. However, the demonstration of nonlinear quantum hydrodynamics, such as superfluidity and Čerenkov flow, which is a consequence of the renormalized elementary excitation spectrum, remains elusive in halide perovskites. Here, using homogenous halide perovskites single crystals, we report, in both one- …

Department of Mechanical and Materials Engineering: Faculty Publications

Peripheral nerve regeneration remains a significant clinical challenge due to the unsatisfactory functional recovery and public health burden. Exosomes, especially those derived from mesenchymal stem cells (MSCs), are promising as potential cell-free therapeutics and gene therapy vehicles for promoting neural regeneration. In this study, we reported the differentiation of human adipose derived MSCs (hADMSCs) towards the Schwann cell (SC) phenotype (hADMSC-SCs) and then isolated exosomes from hADMSCs with and without differentiation (i.e., dExo vs uExo). We assessed and compared the effects of uExo and dExo on antioxidative, angiogenic, antiinflammatory, and axon growth promoting properties by using various peripheral nerve-related cells. …

Epidemiological Aspects Of Equid Herpesvirus-Associated Myeloencephalopathy (Ehm) Outbreaks, Eva Klouth, Yury Zablotski, Jessica L. Petersen, Marco De Bruijin, Gittan Gröndahl, Susanne Müller, Lutz S. Goehring

Department of Animal Science: Faculty Publications

: Equid Herpesvirus Myeloencephalopathy (EHM) is a multifactorial disease following an EHV-1 infection in Equidae. We investigated a total of 589 horses on 13 premises in Europe in search of risk factors for the development of EHM. We found that fever (p < 0.001), increasing age (p = 0.032), and female sex (p = 0.042) were risk factors for EHM in a logistic mixed model. Some breeds had a decreased risk to develop EHM compared to others (Shetland and Welsh ponies; p = 0.017; p = 0.031), and fewer EHV-1-vaccinated horses were affected by EHM compared to unvaccinated horses (p = …

Genetic Code Expansion In Pseudomonas Putida Kt2440, Xinyuan He, Tian Gao, Yan Chen, Kun Liu, Jiantao Guo, Wei Niu

Department of Chemical and Biomolecular Engineering: Faculty Publications

Pseudomonas putida KT2440 is an emerging microbial chassis for bio-based chemical production from renewable feedstocks and environmental bioremediation. However, tools for studying, engineering, and modulating protein complexes and biosynthetic enzymes in this organism are largely underdeveloped. Genetic code expansion for the incorporation of unnatural amino acids (unAAs) into proteins can advance such efforts and, furthermore, enable additional controls of biological processes of the strain. In this work, we established the orthogonality of two widely used archaeal tRNA synthetase and tRNA pairs in KT2440. Following the optimization of decoding systems, four unAAs were incorporated into proteins in response to a UAG …

Life History And Ecology Of The San Emigdio Blue Butterfly (Lepidoptera: Lycaenidae), Gregory R. Ballmer

The Taxonomic Report of the International Lepidoptera Survey

The San Emigdio blue butterfly, Plebulina emigdionis (Grinnell, 1905), occurs in small, scattered colonies in and near the southwestern Mojave Desert of California. Colonies depend on a symbiotic relationship with the ant Formica francoueri (Bolton), and occur only where the ant’s range (primarily in more mesic cis-montane habitats) narrowly overlaps that of the butterfly’s more widely distributed Atriplex larval hosts in more xeric habitats. Colonies of P. emigdionis are often localized around a few host plants and, therefore, sensitive to habitat changes due to anthropocentric causes and environmental stochasticity. The biology, ecology, and status of known colonies of P emigdionis …

The Impact Of Library Publishing Through The Lens Of The United Nations Sustainable Development Goals, Marie O'Neill

Copyright, Fair Use, Scholarly Communication, etc.

Abstract

As library publishing programmes expand around the world, reports and research pertaining to standards and workflows have proliferated. This paper calls for library publishing programmes to explore the impact of their pogrammes at local, national and international level in relation to their contribution to open access publishing, EDI agendas and the United Nations Sustainable Development Goals. The presentation highlights the UN's SDG Publishers Compact and argues that the SDGs are an ideal lens through which library publishers could examine their impact as library publishers have a strong publishing record in areas such as gender, education and climate as examples.

Department of Agronomy and Horticulture: Faculty Publications

Orychophragmus violaceus, referred to as ‘‘eryuelan’’ (February orchid) in China, is an early-flowering ornamental plant. The high oil content and abundance of unsaturated fatty acids in O. violaceus seeds make it a potential high-quality oilseed crop. Here, we generated a whole-genome assembly for O. violaceus using Nanopore and Hi-C sequencing technologies. The assembled genome of O. violaceus was ~1.3 Gb in size, with 12 pairs of chromosomes. Through investigation of ancestral genome evolution, we determined that the genome of O. violaceus experienced a tetraploidization event from a diploid progenitor with the translocated proto-Calepineae karyotype. Comparisons between the reconstructed subgenomes …

The Evolution Of Wildland Fire Risk Management, Matthew Holte

Department of Environmental Studies: Undergraduate Student Theses

Wildland Fire risk management has long been a topic of much discussion. In the past we have focused on immediate danger and how to mitigate it, recently we have started to look at risk with a long-term view. Throughout this paper we will discuss the history of wildland fire, wildland fire policy, and how we got to where we are today. We will also look at how the two different styles of risk management and how we need to use them in a complementary fashion to provide safety to our firefighters, public, and the natural resources that we are protecting.

Canopycam – An Edge-Computing Sensing Unit For Continuous Measurement Of Canopy Cover Percentage Of Dry Edible Beans, Wei-Zhen Liang, Joseph Oboamah, Xin Qiao, Yufeng Ge, Robert M. Harveson, Daran Rudnick, Jun Wang, Haishun Yang, Angie Gradiz

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Canopy cover (CC) is an important indicator for crop development. Currently, CC can be estimated indirectly by measuring leaf area index (LAI) using commercially available hand-held meters. However, it does not capture the dynamics of CC. Continuous CC monitoring is essential for dry edible beans production since it can affect crop water use, weed, and disease control. It also helps growers to closely monitor “yellowness”, or senescence of dry beans to decide proper irrigation cutoff timing to allow the crop to dry down for harvest. Therefore, the goal of this study was to develop a device – CanopyCAM, containing software …

A Review Of Radiation-Induced Alterations Of Multi-Omic Profiles, Radiation Injury Biomarkers, And Countermeasures, Sushil K. Shakyawar, Nitish K. Mishra, Neetha N. Vellichirammal, Lynnette Cary, Tomáš Helikar, Robert Powers, Rebecca E. Oberley-Deegan, David B. Berkowitz, Kenneth W. Bayles, Vijay K. Singh, Chittibabu Guda

Department of Biochemistry: Faculty Publications

Increasing utilization of nuclear power enhances the risks associated with industrial accidents, occupational hazards, and the threat of nuclear terrorism. Exposure to ionizing radiation interferes with genomic stability and gene expression resulting in the disruption of normal metabolic processes in cells and organs by inducing complex biological responses. Exposure to high-dose radiation causes acute radiation syndrome, which leads to hematopoietic, gastrointestinal, cerebrovascular, and many other organ-specific injuries. Altered genomic variations, gene expression, metabolite concentrations, and microbiota profiles in blood plasma or tissue samples reflect the whole-body radiation injuries. Hence, multi-omic profiles obtained from high-resolution omics platforms offer a holistic approach …

Department of Civil and Environmental Engineering: Faculty Publications

Groundwater overuse in different domains will eventually lead to global freshwater scarcity. To meet the anticipated demands, many governments worldwide are employing innovative and traditional techniques for forecasting groundwater availability by conducting research and studies. One challenging step for this type of study is collecting groundwater data from different sites and securely sending it to the nearby edges without exposure to hacking and data tampering. In the current paper, we send raw data formats from the Internet of Things to the Distributed Data Storage (DDS) and Blockchain (BC) edges. We use a distributed and decentralized architecture to store the statistics, …

The Vine Street Irregulars: A Chronicle Of Graduate Student Life And Politics At The University Of Nebraska-Lincoln 1975–1976, Michael R. Hill

Zea E-Books Collection

The memories recalled in the twenty-seven essays in the volume are anchored in sometimes intense and sometimes admittedly naive graduate student experiences at the University of Nebraska-Lincoln during the 1970’s. Master’s degree in hand, I returned to graduate study at Nebraska in 1972 after four years in the military, benefitting not only from the G.I. Bill, but also from a National Defense Education Act Fellowship. I was increasingly wise to the ways of administrative bureaucrats who were sometimes enlightened, sometimes punitive, draconian, and exploitive, or — far more often — simply moribund. As adult students, we wanted fair play and …

Inactivation Of Salmonella In Nonintact Beef During Low-Temperature Sous Vide Cooking, Heather B. Hunt, Samuel C. Watson, Byron D. Chaves, Gary Sullivan

Department of Animal Science: Faculty Publications

Sous vide cooking is a method of food preparation in which food is vacuum sealed and cooked in a water bath that is set to a precise temperature and circulated by a sous vide device. Due to ease of use and affordability, this cooking method has grown increasingly popular in food service kitchens and domestic settings. However, low‐temperature, long holding time sous vide cooking recommendations from manufacturers and chefs in popular press raise food safety concerns – specifically those for the preparation of nonintact beef products. The objective of this experiment was to address these concerns by validating a 5 …

Warning: The Nfl Claims Copyright Ownership Of …. Everything?, Lauren Bruning

Nebraska Law Bulletin (Selected Issues)

The issue of overreaching copyright warnings is not one to be ignored. This Note suggests three potential ways to prevent the issue. First, all copyright warnings should acknowledge the doctrine of fair use. Fair use is essential to copyright law–to business, to progress, to innovation. Second, we must strengthen the copyright misuse doctrine. The NFL is one of potentially many copyright owners flying under the radar due to this underdeveloped, incomplete defense. Copyright misuse is a doctrine that has the potential to play an important role in protecting the public policy underlying copyright law, plus it is uniquely positioned to …

The “Big Six”: Hidden Emerging Foodborne Bacterial Pathogens, Mona G. Alharbi, Rashad R. Al-Hindi, Ahmed Esmael, Ibrahim A. Alotibi, Sheren A. Azhari, Mazen S. Alseghayer, Addisu D. Teklemariam

Nebraska Center for Virology: Faculty Publications

Non-O157 Shiga toxin-producing Escherichia coli (STEC) are emerging serogroups that often result in diseases ranging from diarrhea to severe hemorrhagic colitis in humans. The most common non-O157 STEC are O26, O45, O103, O111, O121, and O145. These serogroups are known by the name “big six” because they cause severe illness and death in humans and the United States Department of Agriculture declared these serogroups as food contaminants. The lack of fast and efficient diagnostic methods exacerbates the public impact of the disease caused by these serogroups. Numerous outbreaks have been reported globally and most of these outbreaks were caused by …
