Considering The Use Of The Terms Strain And Adaptation In Prion Research, Robert M. Zink

School of Natural Resources: Faculty Publications

Evolutionary biologists and disease biologists use the terms strain and adaptation in Chronic Wasting Disease (CWD) research in different ways. In evolutionary biology, a strain is a nascent genetic lineage that can be described by a genealogy, and a phylogenetic nomenclature constructed to reflect that genealogy. Prion strains are described as showing distinct host range, clinical presentation, disease progression, and neuropathological and PrP biochemical profiles, and lack information that would permit phylogenetic reconstruction of their history. Prion strains are alternative protein conformations, sometimes derived from the same genotype. I suggest referring to prion strains as ecotypes, because the variant phenotypic …

Deepnec: A Novel Alignment-Free Tool For The Characterization Of Nitrification-Related Enzymes Using Deep Learning, A Step Towards Comprehensive Understanding Of The Nitrogen Cycle, Naveen Duhan

Student Research Symposium

Abstract: Nitrification is an important microbial two-step transformation in the global nitrogen cycle, as it is the only natural process that produces nitrate within a system. The functional annotation of nitrification-related enzymes has a broad range of applications in metagenomics, agriculture, industrial biotechnology, etc. The time and resources needed for determining the function of enzymes experimentally are restrictively costly. Therefore, an accurate genome-scale computational prediction of the nitrification-related enzymes has become much more important.In this study, we developed an alignment-free computational approach to determine the nitrification-related enzymes from the sequence itself. We propose deepNEC, a novel end-to-end feature selection and …

Pyseqrna: An Automated Python Package For Advanced Rna Sequencing Data Analysis And Annotation, Naveen Duhan

Student Research Symposium

Abstract: With the advent of Next-Generation Sequencing (NGS) technologies, numerous data is being generated every day, however, streamlined analysis remains a big hurdle to efficiently use the technology. A large number of algorithms, statistical methods, and software tools have been developed in recent years to perform the individual analysis steps of various NGS applications. Some NGS applications data analysis procedures are therefore very complex, requiring several program tools to be downloaded for their various processing steps. There is a significant room for the development of scalable computing environments that link the individual software components to automated workflows to efficiently and …

Translating -Omics Big Data: Comprehensive Understanding Of Host-Pathogen Interactions To Control Bacterial Blight In Alfalfa Using Computational Approaches, Raghav Kataria

Student Research Symposium

Plant infectious diseases are a major threat to the crops, owing to economic losses to the agriculture industry worldwide. Molecular interactions between the host and pathogen play a critical role in understanding the basis of pathogenesis. Majority of the Pseudomonas syringae strains are known to cause frost injury in plants, amongst which, P. syringae pv. syringae ALF3 is asserted to be a causal organism of bacterial stem blight in Medicago sativa (alfalfa). We elucidated the genome-scale host-pathogen interactions (HPIs) between alfalfa and P. syringae using two intense computational approaches: interolog (homology-based) and the domain-based method (based on 3D structure of …

Examining Urban Soil Quality And Contamination Along The Wasatch Front, Frank Oliver

Student Research Symposium

Urban soil contamination has become an increasingly prevalent concern within residential developments and the expansion of urban agriculture. The purpose of this study was to establish an urban soil survey along the Wasatch Front to examine the concentrations of common contaminants and general soil quality in urban farms and community gardens during 2020-2021. Areas of concern include 1) heavy metals: lead, arsenic, cadmium, and chromium, 2) organic contaminants- petroleum hydrocarbons, polycyclic aromatic hydrocarbons, and volatile organic carbon, 3) pH, 4) soil salinity, and 5) elevated macronutrient levels. Measured contaminant concentrations will be compared to EPA regional screening levels (RSL) along …

Revegetation Of Native Plant Communities In Great Salt Lake Wetlands: The Effects Of Native Seed Mix Composition And Sowing Density, Laura Beck

Student Research Symposium

One of the threats currently facing Great Salt Lake wetlands is Phragmites australis. Its rapid expansion since 1987 has displaced native vegetation and changed the composition of plant communities. Removal is very costly and takes multiple years of different treatments like herbicide, mowing, and flooding. To ensure Phragmites australis does not return, native seeds will need to be sown. This experiment is to determine the best seed composition and sowing density. In the USU greenhouse, I will sow four different native seed mixes: 100% desirable perennial natives, 75% perennial natives and 25% fast growing natives, 50% perennial natives and 50% …

The Amungme And The Environment: Environmental Justice History And Consumerism, Kole A. Dawson

Phi Alpha Theta Pacific Northwest Regional Conference

The Amungme are one of hundreds of Papuan people groups who lived in the Indonesian province in New Guinea for thousands of years. This group subsisted in their environment by hunting, cultivation of small crops, and practicing pig husbandry. In the late 1960s, seeking foreign capital to boost the nation’s economy, the president of Indonesia signed a contract with Freeport McMoRan Copper and Gold. Freeport began mining in the early 1970s, eventually opening one of the world’s largest gold mines. Excavating sacred Amungme sites, Freeport’s massive pollution to the land and water destroyed the indigenous people’s environment both spiritually and …

Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 the International Union for Conservation of Nature (IUCN) called for development of a “Green List of Species” (now the IUCN Green Status of Species). A draft Green Status framework for assessing species’ progress toward recovery, published in 2018, proposed 2 separate but interlinked components: a standardized method (i.e., measurement against benchmarks of species’ viability, functionality, and preimpact distribution) to determine current species recovery status (herein species recovery score) and application of that method to estimate past and potential future impacts of conservation based on 4 metrics (conservation legacy, …

Can’T Bear It! Employing Culturally Sensitive Initiatives To Reduce Bear Bile Demand In Northern Vietnam, Alicia Ngo, Shannon Randolph

EnviroLab Asia

Over the past 30 years, the combination of over-hunting, habitat loss, and increased bear bile demand has caused significant declines in Asiatic black bear (aka moon bear; Ursus thibetanus) and sun bear (Helarctos malayanus) populations. In Eastern medicine, bear bile is extracted from the gallbladders of bears and is then used to treat a wide range of inflammatory, liver, and degenerative ailments. However, the use of bear bile has had significant impacts on bear populations. Given that communities in Northern Vietnam have a lengthy history of using bear bile and bear bile is easily accessible, merely advocating …

On The Third Moment Of L(½​, ΧD​) {Ii}: The Number Field Case, A. Diaconu, Ian Whitehead

Mathematics & Statistics Faculty Works

We establish a smoothed asymptotic formula for the third moment of quadratic Dirichlet L-functions at the central value. In addition to the main term, which is known, we prove the existence of a secondary term of size x^¾. The error term in the asymptotic formula is on the order of O(x^⅔+δ) for every δ > 0.

Teacher Educators Learning With Prospective Teachers: Finding Relevant Mathematics In Our (Their) Lives, Lindsay M. Keazer, Eryn Stehr Maher

Department of Mathematical Sciences Faculty Publications

Two mathematics teacher educators (MTEs) discuss the mathematical contexts generated by prospective teachers (PTs) when pushed to look for relevant mathematics in their lives and communities. Through collaborative teacher action research focused on iterations of collecting, categorizing, and discussing PTs’ mathematical contexts, and posing selected examples for PTs’ own examination, layers of learning occurred for both PTs and MTEs. PTs began to craft more personalized, story-like contexts, seemingly noticing more mathematics in their lives. MTEs were unexpectedly pushed to clarify their thinking about what it means to develop contexts that are authentic and relevant, and to contemplate how their actions …

Is Mitigation Of Drought Stress By Zinc Oxide Nanoparticles Driven By A Nano-Specific Mechanism Or Mitigation Of Micronutrient Deficiency?, Justin Deakin

Student Research Symposium

It has been reported that zinc oxide (ZnO) nanoparticles (NPs) can promote drought tolerance in crops when used as soil amendments. However, many of these experiments were conducted in Zn-deficient growth media with no comparison to currently available Zn fertilization methods, making it unclear if the benefits from adding ZnO NPs were caused by a nano-specifc mechanism or simply by the mitigation of a micronutrient deficiency. A review of the literature shows that of 12 published experiments considering the effects of ZnO NPs on plant health, 5 out of 6 studies that did not include a comparison to currently available …

Learning Sampling Policy For Faster Derivative Free Optimization, Zhou Zhai, Bin Gu, Heng Huang

Machine Learning Faculty Publications

Zeroth-order (ZO, also known as derivative-free) methods, which estimate the gradient only by two function evaluations, have attracted much attention recently because of its broad applications in machine learning community. The two function evaluations are normally generated with random perturbations from standard Gaussian distribution. To speed up ZO methods, many methods, such as variance reduced stochastic ZO gradients and learning an adaptive Gaussian distribution, have recently been proposed to reduce the variances of ZO gradients. However, it is still an open problem whether there is a space to further improve the convergence of ZO methods. To explore this problem, in …

Synthesis And Characterization Of Regioregular Cross-Conjugated Poly(Thienylene Vinylene)S, Yousef M. Katba Bader

Chemistry and Chemical Biology ETDs

Poly(thienylene vinylene)s (PTVs) is special a class of conjugated polymers (CPs) that show remarkable optoelectronic properties and promising applications. The main reason that hinders their application, is the lack of synthetic methodologies for preparing new derivatives with various functionality. Developing new PTVs with improved structures based on structure-property relationships increases the potential of utilizing this type of polymers in advanced applications. Most available preparation methods lead to regio-random PTVs (ra-PTVs) structures due to the different placement of the sidechain in the polymer backbone, which results in reduced crystallinity. In this study, we developed a novel strategy that produces a series …
