Faculty, Staff and Student Publications

Developers and users of artificial-intelligence-based tools for automatic contouring and treatment planning in radiotherapy are expected to assess clinical acceptability of these tools. However, what is 'clinical acceptability'? Quantitative and qualitative approaches have been used to assess this ill-defined concept, all of which have advantages and disadvantages or limitations. The approach chosen may depend on the goal of the study as well as on available resources. In this paper, we discuss various aspects of 'clinical acceptability' and how they can move us toward a standard for defining clinical acceptability of new autocontouring and planning tools.

Comparisons Of Small Unmanned Aircraft Systems And Agro-Terrestrial Surveys: Techniques To Determine Field Elevation Surfaces For Improved Crop And Water Management., Richard A. Pickett Jr

Student Theses and Dissertations

Row crop agriculture in Arkansas relies predominantly on groundwater resources for irrigation. This places great demand on the Mississippi River Valley Alluvial Aquifer (MRVAA), which is in a current state of decline. The Eastern Arkansas region produces commodity crops including soybeans, rice, corn, cotton, and peanuts, all of which utilize irrigation for optimal productivity. Conservation practices that reduce groundwater use include precision land leveling, multiple inlet rice irrigation, and computerized hole size selection for furrow irrigation. To collect elevation data to irrigate efficiently, these practices require precision agriculture technology, more specifically Real-Time Kinematic–Global Navigation Satellite Systems (RTK-GNSS). As RTK-GNSS technologies …

Evidence Of Sea Level Rise At The Peruvian Coast (1942-2019), Bismarck Jigena-Antelo, Carol Estrada-Ludeña, Stephan Howden, Wilmer Rey, Jorge Paz-Acosta, Patricia Lopez-García, Eric Salazar-Rodriguez, Nieves Endrina, Juan J. Muñoz-Pérez

Faculty Publications

The present work aims to analyze the variability of the sea level of the Peruvian coast with time series over a long observation period (Seventy-eight years, from 1942 to 2019). Data came from the Talara, Callao and Matarani tide gauge stations located at the north, center and south of the coast. Variations of sea level as well as air and seawater surface temperature were analyzed. Among the different scenarios studied, a sea level rise of 6.79, 4.21 and 5.16 mm/year for Talara, Callao and Matarani, respectively was found during the 1979–1997 nodal cycle. However, these results decreased significantly during the …

The Laminar Seabed Thermal Boundary Layer Forced By Propagating And Standing Free-Surface Waves, S. Michele, A. G.L. Borthwick, Ton S. Van Den Bremer

School of Engineering, Computing and Mathematics

A mathematical model is developed to investigate seabed heat transfer processes under long-crested ocean waves. The unsteady convection–diffusion equation for water temperature includes terms depending on the velocity field in the laminar boundary layer, analogous to mass transfer near the seabed. Here we consider regular progressive waves and standing waves reflected from a vertical structure, which complicate the convective term in the governing equation. Rectangular and Gaussian distributions of seabed temperature and heat flux are considered. Approximate analytical solutions are derived for uniform and trapezoidal currents, and compared against predictions from a numerical solver of the full equations. The effects …

Breaking The Ncaa's Two-Tiered System: Attaining Full Scholarships For Equivalency Sport Athletes, Mason Corbett

Texas A&M Law Review

In June of 2021, the Supreme Court released the Alston decision, invalidating NCAA restrictions on educational-related benefits for Division I football, men’s basketball, and women’s basketball student-athletes. Alston laid the groundwork for future challenges to NCAA rules, with Justice Kavanaugh explicitly encouraging further challenges to NCAA rules in his concurring opinion. This Comment reviews NCAA rules limiting the number of scholarships below the number of scholarship roster spots for certain sports. If these rules were challenged under the Alston framework, they likely would not stand up under the antitrust review for NCAA rules established by Alston.

Furthermore, this Comment …

Machine Learning Methods For Computational Phenotyping Using Patient Healthcare Data With Noisy Labels, Praveen Kumar

Computer Science ETDs

Positive and Unlabeled (PU) learning problems abound in many real-world applications. In healthcare informatics, diagnosed patients are considered labeled positive for a specific disease, but being undiagnosed does not mean they can be labeled negative. PU learning can improve classification performance, and estimate the positive fraction, α, among unlabeled samples. However, algorithms based on the Selected Completely At Random (SCAR) assumption are inadequate when the SCAR assumption fails (e.g., severe cases overrepresented), and when class imbalance is substantial. This dissertation presents and evaluates new algorithms to overcome these limitations. The proposed methods outperform the state-of-art for α-estimation, enhance classification performance, …

Theses and Dissertations

Online social networks have been a target of misinformation and manipulative campaigns in recent years. Although, recent literature has been developed to identify individual suspicious accounts that are connected to coordinated manipulative campaigns on platform such as Twitter, there is a need to detect and characterize large-scale coordinated efforts within other contexts. YouTube is the one of the most popular and visited websites in the world and has also been a target of misinformation and online campaigns in recent years, making analysis of suspicious behaviors within the platform vital for the research community and policymakers at large. In this research, …

Recalibrating Governance: Part Iv, Ishrat Husain Dr.

Faculty Research - Newspaper and Magazine Articles

Pakistan faces two serious problems in education. Twenty million children are out of school and learning outcomes from existing schooling are quite weak. To resolve both these problems, governance reforms are badly needed. These reforms should begin with a clear division of responsibilities between the federal, provincial and district governments in the delivery of services. While the federal government should focus on higher education financing, regulations and standards and curriculum, the provincial governments should be made responsible for college education, technical and vocational education. The district governments will have the exclusive powers to manage and operate primary and secondary education …

The Process Theology Of John Elof Boodin, Michael A. Flannery

Libraries Professional Work

Despite his impeccable academic pedigree, a protégé of Josiah Royce and a friend and student of William James, John Elof Boodin is nearly forgotten today among American philosophers; hence, an essential aspect of his thought lost to history is his contribution to process theology. The leading features of process thought demonstrate Boodin’s connections to this unique theology and show it to have been established early on, as early as 1900 and 1904. This places Boodin’s writing on process philosophy/theology well before Alfred North Whitehead, the putative pioneer in modern process metaphysics, by more than twenty years, and co-extensive with Henri …

School of Earth, Environmental, & Marine Sciences Faculty Publications

Simple Summary

Although studies have started to show that the effects of cover crops can translate into the cash cropping season, there is little information on the cascading effects of cover crops on the subsequent cash crop defenses, especially against polyphagous herbivores. To bridge this information gap, we conducted a field and laboratory study to investigate the cascading effects of different cover crop species on the subsequent cash crop defense against the polyphagous herbivore fall armyworm (Spodoptera frugiperda) across three fields in the Lower Rio Grande Valley in south Texas. Our field and laboratory results revealed that cover crop treatments …

This work presents the first measurement of the proton light yield of a water-based liquid scintillator (WbLS) formulated from 5% linear alkyl benzene (LAB), at energies below 20 MeV, as well as a measurement of the proton light yield of a pure LAB + 2 g/L 2,5-diphenyloxazole (PPO) mixture (LABPPO). The measurements were performed using a double time-of-flight method and a …

Drought Stress Prediction And Propagation Using Time Series Modeling On Multimodal Plant Image Sequences, Sruti Das Choudhury, Sinjoy Saha, Ashok Samal, Anastasios Mazis, Tala Awada

School of Natural Resources: Faculty Publications

The paper introduces two novel algorithms for predicting and propagating drought stress in plants using image sequences captured by cameras in two modalities, i.e., visible light and hyperspectral. The first algorithm, VisStressPredict, computes a time series of holistic phenotypes, e.g., height, biomass, and size, by analyzing image sequences captured by a visible light camera at discrete time intervals and then adapts dynamic time warping (DTW), a technique for measuring similarity between temporal sequences for dynamic phenotypic analysis, to predict the onset of drought stress. The second algorithm, HyperStressPropagateNet, leverages a deep neural network for temporal stress propagation using hyperspectral imagery. …

Evaluation Of Polyacrylamide (Pam) Effects On Irrigation Efficiency, Soil Conservation, And Water Quality In Midsouth Cotton Production, Brittany D. Barnes

Student Theses and Dissertations

The polymer, polyacrylamide (PAM), is a high molecular weight, chemical anionic polymer that is prescribed and used for irrigation improvement in row crops primarily in the United States. A field research study was conducted in 2014, 2015 and 2016 in Northeast Arkansas to evaluate how addition of PAM in furrow irrigation affected soil erosion, water infiltration, movement of nutrients and sediments, and crop yields in cotton (Gossypium hirsutum). Overall results from the study were mixed. Sediment loss was similar among treatments. Irrigation advancement rates were not significantly different. No differences in crop yield were observed associated with PAM. Differences in …

Evaluation Of Woodchip Bioditch Reactors As A Nutrient Reduction Conservation Strategy, Geoffrey K. Payne

Student Theses and Dissertations

Continued increases in nitrogen and phosphorus loads in waterways cause problems with water quality, impacting human health, the economy, and the environment. To reach nutrient load reduction targets, innovative conservation strategies should be evaluated. This study aimed to assess (1) the potential of using woodchip bioditch reactors for the mitigation of nitrate (NO3-) and soluble reactive phosphorus (SRP) in agricultural waterways; (2) the influence of orientation of the bioditch reactor to flow direction on NO3- and SRP concentrations and loads; and (3) the impact that differing wet/dry cycles have on NO3- and SRP concentrations and loads when bioditch reactors are …

Assessment Of Variable Rate Nitrogen Application On Rice Cultivars Using Remote Sensing, Rush Matthew Evans

Tennessee Rural Middle School Teachers' Perceptions Of Academic Goal Setting For Students, Amy Woolum

Ed.D. Dissertations

Since the 1960s, business leaders and educators used the idea of goal setting theory as a guide to success. Teachers who implemented goal setting strategies contributed to student success and achievement. During my study, I found little existing literature focused on academic goal setting implementation for students in Tennessee rural middle schools containing grades six through eight. The purpose of this qualitative interpretive study was to investigate Tennessee rural middle school teachers’ perceptions about implementing academic goal setting for students. I sent an online Google Forms questionnaire to 117 certified and licensed teachers in varying Tennessee rural middle schools. After …

Recovering The Art Of Testimony, As Embodied Within The Historical Black Church, As A Missionally Formative Practice, Christopher Cobbler

DMin Project Theses

This February 2023 Doctor of Ministry project thesis at Lipscomb University aims to consider how the art of testimony, as embodied within the traditional Black church, functions as missionally formative practice. The purpose of this project is to examine the ways testimony service can be utilized to reimagine an alternative eschatological community in a postmodern society. Testimony, in the historical Black Church, was a central component to the life of the congregation; it served as a tool to shape and navigate the theological imagination within a particular community, it cultivated and nurtured centered belonging and was a primary vehicle for …

Physics

Ecosystems constantly change, yet managers often lack information to move beyond static habitat assumptions. As human impacts and geographic information systems advance, it is important and feasible to quantify past habitat boundary shifts to inform management decisions (e.g. protective perimeters) robust to near-term habitat changes. This is the case in eelgrass (Zostera spp.), an ecosystem engineer that forms dynamic, often protected meadows. Practitioners protect areas to avoid human stress to eelgrass, but they can lack quantitative descriptions of the near-term potential for eelgrass meadows to shift into unprotected areas. Here, we quantified interannual eelgrass meadow boundary shifts within 23 sites …
