Characterizing The Impact Of Cover Crop On Soil Microbiome Function Affecting C And N Inputs In Corn Production System, Durga Purushotham Mahesh Chinthalapudi

Theses and Dissertations

Cover cropping (CC) is a widely adopted strategy to improve soil health and microbial diversity in agroecosystems. However, its influence on microbial community dynamics and ecosystem functions remains context-dependent, particularly under variable nitrogen (N) inputs. This dissertation integrates a three-year field study (2021-2024) in corn-based systems with a meta-analysis of 473 soil samples from diverse Mississippi cropping systems to evaluate CC effects on soil microbial structure, function, and ecosystem multifunctionality. In the field study, soil bacterial and fungal communities were profiled using high-throughput amplicon sequencing (16S rRNA for bacteria, ITS2 for fungi). Seven CC treatments ryegrass, balansa, radish, red clover, …

Edna Surveillance And Population Genomics Of The Invasive Loaches Introduced To The United States, Tobin J. Davidson

Theses and Dissertations

Invasive species represent a growing threat to the ecosystems and economies of the United States. The southeastern United States is an aquatic biodiversity hotspot, and the decline of multiple native species already facing extinction is attributed to a rapidly growing number of nonindigenous freshwater fishes. Next-generation sequencing was used to analyze the population genomics of several populations of Pond Loach (Misgurnus anguillicaudatus) introduced to the United States. Three evolutionarily significant units of Misgurnus loaches were found, suggesting the invasion of multiple different species in the United States. Additionally, noninvasive environmental DNA (eDNA) protocol designed for early detection of invasive freshwater …

Investigation Of Guayule Resin As An Oil-Based Wood Treatment, Jordan Miller

Theses and Dissertations

Development of alternative treatments for wood product protection is an ongoing focus throughout the wood products industries. All manufacturers hope to increase the use life of their products, while ensuring that their products do not have a harmful impact on their surrounding environment. One way of approaching this is to source potential components from other agricultural sources. Guayule resin is produced as a by-product of rubber extraction from the guayule plant (Parthenium argentatum). The resin has been reported to have insecticidal and microbial properties, but there are numerous problems with utilization, including how to extract it and apply it due …

A Mathematical Theory Of Epitaxial Growth, Brock C. Price

Theses and Dissertations

In this dissertation we investigate several PDE models of Epitaxial growth. These models are fourth-order PDE’s featuring exponential nonlinearities as well the p-Laplacian and 1-Laplacian. The presence of the exponential nonlinearity is what provides the main mathematical difficulty. Theexponent in particular does not have enough estimates to guarantee any compactness. Because of this, one has to allow the inclusion of a singular portion to the exponent in the sense of the Lebesgue decomposition theorem. In thefirst chapter weinvestigate a related epitaxial growth, with transition rates of the Metropo lis variety and a linear exponent. The metropolis rates induce an extra …

Unraveling Quantum Properties Of Novel Two-Dimensional Systems Using A First-Principles Approach, Binod Regmi

Theses and Dissertations

We used first-principles density functional theory (DFT) to investigate the structural, electronic, and magnetic properties of an oxygen crystal in a copper slab, a ferrimagnetic electride with highly tunable magnetic anisotropy energy (MAE), and the Fermi surface analysis of different kagome metal phases. The Perdew-Burke-Ernzerhof (PBE) exchange-correlation functional was used in the Vienna ab initio simulation package (VASP) for all these calculations. Because of dimensionality reduction, the electronic properties of copper change significantly at the two-dimensional (2D) scale due to whichwe observe more reconstruction in the geometry of the Fermi surface. Dimensionality reduction also influences charge transport. Moreover, we present …

Specifically investigating how arm motion enhances performance at the muscle level and how the muscle contributions of the lower extremities differ in jumps with and without arm motion. Three male and three female participants performed three jumps with arms and three jumps without arms. The longest jumps with and …

Acute Toxicity Of Arsenate And Arsenite In Two Scleractinian Coral Species: Acropora Cervicornis And Orbicella Faveolata, Cailey Dorman

All HCAS Student Capstones, Theses, and Dissertations

Inorganic arsenic (As), specifically arsenate (As(V)) and arsenite (As(III)) are well-documented toxicants to a range of marine organisms. However, their specific impacts on coral reef species remain largely unstudied. This study is the first to assess the acute and subacute toxicity of inorganic arsenic on two threatened scleractinian coral species, Acropora cervicornis and Orbicella faveolata. Corals were exposed for 96 hours to five analytically verified concentrations and a negative control of either arsenate or arsenite. Toxicity was evaluated through three endpoints: mortality (LC50), coral condition (EC50), and photosynthetic efficiency (IC50). The lethal concentrations to result in 50% mortality (LC50) …

The Trophic Ecology Of The Snipe Eel Avocettina Infans (Anguilliformes: Nemichthyidae) In The Deep-Pelagic Gulf Of Mexico, Emma N. Schindler

All HCAS Student Capstones, Theses, and Dissertations

The Nemichthyidae (snipe eels) are ubiquitous in the deep-pelagic waters of tropical and temperate latitudes, and in some ecosystems are among the dominant fishes. In the deep waters of the Gulf of Mexico, the nemichthyid species Avocettina infans is one of the dominant large predators. This prompted the current study, where an extensive sample set was utilized to characterize the abundance of the family in total, and the vertical distribution and trophic ecology of A. infans specifically. The nemichthyid abundance from 0 – 1500 m was estimated at 1,106.58 individuals per billion cubic meters, the largest portion of which was …

Lysosomes As Gatekeepers: How Lic1-Mediated Trafficking Regulates Angiogenesis And Vascular Morphogenesis, Dymonn Johnson

Arts & Sciences Graduate Student Theses and Dissertations

Dynein cytoplasmic 1 light intermediate chain 1 (LIC1, DYNC1LI1) is a core subunit of the dynein motor complex that plays a critical role in cytoplasmic cargo trafficking, including Rab-mediated endosomal recycling and lysosomal degradation. LIC1 interacts with various cargo adaptors, such as RILPL1 and RILPL2, to regulate these processes, and defects in this gene are predicted to impair dynein motor function, Rab binding, and lysosomal trafficking. Here, we identified a dync1li1 zebrafish mutant with a premature stop codon at the exon 12/13 splice acceptor site, that exhibits increased angiogenesis. In vitro, LIC1-deficient human endothelial cells show elevated cell surface levels …

2020-Current year OA Pubs

Rapid development of memristive elements emulating biological neurons creates new opportunities for brain-like computation at low energy consumption. A first step toward mimicking complex neural computations is the analysis of single neurons and their characteristics. Here we measure and model spiking activity in artificial neurons built using diffusive memristors. We compare activity of these artificial neurons with the spiking activity of biological neurons measured in sensory, pre-motor, and motor cortical areas of the monkey (male) brain. We find that artificial neurons can operate in diverse self-sustained and noise-induced spiking regimes that correspond to the activity of different types of cortical …

A Multi-Measurement Study Of The Relation Between Deliberation And Volition, Guillaume P. Pech, Emilie A. Caspar, Elisabeth Pacherie, Axel Cleeremans, Uri Maoz

Psychology Faculty Articles and Research

Historically, voluntary action and volition more generally have been investigated through the lens of meaningless decisions. Importantly, these findings have been used in the debate about key notions like free will and moral responsibility. However, more recent claims have challenged the possibility of generalizing findings from a meaningless context to a more meaningful one. The current study investigates the markers of volition, specifically comparing meaningful and meaningless decisions. In an effort to maximize their monetary gain, 50 participants repeatedly deliberated between two options, making either rewarded choices—hard-deliberation decisions (where the options differed along two dimensions) or easy-deliberation decisions (where the …

Patient Experience Journal

Interprofessional collaboration (IPC) is considered the highest standard of practice for delivering care to patients with multiple, complex, and chronic conditions. Despite reported benefits of IPC, the voice of the care receiver and how or whether they experience IPC is underexplored. Our objective was to examine patients’ experiences with IPC in two rural primary care settings in the U.S., where the burden of multiple chronic conditions (MCCs) is coupled with lower life expectancies and reduced access to care. We used a semi-structured interview to assess patients’ experiences within 72 hours after an IPC healthcare visit. This study, conducted in two …

Role Of Patient-Reported Measures (Prms) In Addressing Ethical Challenges During Telemedicine Consultation: A Narrative Review, Asiya Attar, Kasturi Shukla

Patient Experience Journal

Introduction: Telemedicine has revolutionized medical care delivery by emphasizing on Patient-Centred Care (PCC). Patient Reported Measures (PRMs) can assist in providing PCC since it assesses the treatment outcomes and patient experience. However, using PRMs is not just limited to gauging clinical efficiency; it can also play a role in addressing the ethical challenges in telemedicine. Yet this aspect of PRMs remains underexplored. Method: Literature search was conducted using a combination of keywords from the Google Scholar, Scopus, and Web of Science databases. 126 peer-reviewed journal articles in English from 2015 to 2024 were screened, and 34 relevant full-text …
