Evaluating Spatial Variability Of Corn Yield Response To Phosphorus Fertilizer For Improved Precision Phosphorus Management, Jennifer Fridgen

Theses and Dissertations--Plant and Soil Sciences

Soil scientists did not develop soil test-based fertilizer recommendations to support precision nutrient management. Knowledge of crop responses to applied essential nutrients, such as phosphorus (P), and the processes governing these responses at high spatial resolution are necessary to improve precision agronomic recommendations. This dissertation investigates the limitations of current soil sampling methodologies and recommendation frameworks for crop response to fertilizer, with particular emphasis on P fertility in Kentucky (KY) corn production. The first study examined the relationship between the resolution of systematic grid sampling and the spatial structure of soil test variables (Mehlich-3 P (M3P), Mehlich-3 potassium (M3K), and …

Just A Slip: Cognitive Distortions Associated With Lapse And Relapse In Recovery, Matthew Karr

PCOM Psychology Dissertations

Substance use rates in the United States continue to rise despite low treatment utilization. Research has indicated the function of distorted patterns of thinking that can influence the relapse process. This study aimed to examine the relationships between relapse patterns, length of abstinence, and endorsed rates of cognitive distortions on the Cognitive Distortions Scale (CDS). This study sought participants 18 years or older with a history of problematic substance use and substance use treatment within the past 2 years. Participants were recruited through social media sites. Proposed statistical analyses included Pearson’s product-moment correlation, analysis of variance (ANOVA), and multivariate analysis …

The Devil Is In The Det[Ai]Ls: Ai Agents, Ghost Students, And The Crisis Of Verified Presence In An Agentic Ai World, Aras Bozkurt, Helen Crompton, Caroline Fell Kurban

STEMPS Faculty Publications

The transition from reactive Generative Artificial Intelligence (GenAI) to agentic AI systems marks a categorical shift in digital education, moving beyond simple content generation to goal-oriented, autonomous execution. This paper explores the emergence of the “ghost student”: a digital surrogate created by the coupling of Large Language Models (the “mind”) and agentic AI browsers (the “body”). These entities are capable of navigating Learning Management Systems (LMS), engaging with content, and completing assessments with human-like mimicry, often rendering the actual learner’s presence optional. We argue that this phenomenon creates a verification gap that traditional proctoring and detection tools are structurally unable …

The Weight Of Stigma, Rebekah A. King, Michael S. Sinha

All Faculty Scholarship

Many health care providers, both implicitly and explicitly, perpetuate stigma in their treatment of patients classified as obese. While medical professionals understand that a one-size-fits-all approach to treatment is ineffective, patients classified as obese are frequently offered limited treatment options that fail to account for their unique needs. Access to a range of effective treatment options has historically been limited, but new GLP-1 receptor agonist medicines like Wegovy (semaglutide) and Zepbound (tirzepatide), have shown incredible promise in addressing the obesity crisis. Unfortunately, these transformative drugs are costly, in high demand, and not widely covered by insurance, rendering them inaccessible for …

Data From: Complete Mitochondrial Genomes Of The Spring Pygmy Sunfish (Elassoma Alabamae), Kayla M. Fast, David Lee Pounders, Mayah P. Peterson, Michael W. Sandel

Research Data

The Spring Pygmy Sunfish, Elassoma alabamae (Mayden, 1993), is a small species of sunfish (Centrarchiformes) endemic to tributaries to the middle Tennessee River in north Alabama. Elassoma alabamae is the most geographically restricted member of Elassoma and the only species found above the fall line. This species was twice considered extinct and was listed under the Endangered Species Act (ESA) as threatened in 2013. To date, surveys for this species have been limited to traditional invasive methods using dipnets and seines. In order to reduce impacts on sensitive populations, we sequenced the mitochondrial genome with the intent of developing a …

The Underexplored Complexity Of Pancreatic Cancer: Early Dissemination And Quiescence, Nivedeta Krishna Kumar, Annant Bir Kaur, Surinder K. Batra, Moorthy P. Ponnusamy

Journal Articles: Biochemistry & Molecular Biology

Pancreatic cancer has been renowned for its aggressive nature and occasionally manifests periods of dormancy, presenting a perplexing challenge in studying disease progression. Despite surgery, many patients relapse due to dormancy and chemoresistance, resulting in recurrence and death within a few years. Studies also suggest that pancreatic cancer disseminates early on, spreading to secondary organs with no evidence of disease. The lingering question is: how, where, and when does pancreatic cancer recur and spread? Herein, we explore evidence for clinically dormant pancreatic cancer cells, examining the roles of quiescence and stemness populations and their interactions with the tumor microenvironment. Understanding …

The aims were to evaluate panel performance, to compare the panels' performance with that of cancer antigen 19-9 (CA19-9) alone, and to evaluate the performance of new combinations of the individual biomarkers.

EXPERIMENTAL DESIGN: Ten biomarkers representing eight biomarker panels and CA19-9 were evaluated using plasma, serum, and germline DNA from 140 stage I to IV pancreatic ductal adenocarcinoma (PDAC) cases and 140 controls from three tertiary care institutions, with controls frequency matched to cases on age …

Rac1 Gtpase Regulates The Scfβtrcp-Mediated Degradation Of Claspin And The Cellular Response Of Pancreatic Cancer Cells To Gamma Rays, Neha Chaudhary, Tabbatha N. Somers, Surinder K. Batra, Ying Yan, Michel M. Ouellette

Journal Articles: Biochemistry & Molecular Biology

BACKGROUND/OBJECTIVES: Pancreatic ductal adenocarcinomas (PDACs) are lethal tumors exhibiting resistance to most cancer therapeutics, particularly DNA-damaging agents. The

METHODS: Western blot analyses were used to assess the impacts of Rac1 inhibition on the components of the ATR/Chk1 cascade.

RESULTS: Here, we show that Rac1 inhibition disrupts ATR/Chk1 signaling by promoting degradation of Claspin, a key component of the fork protection complex needed for the Ser345-phosphorylation of Chk1 by ATR. In PDACs and normal pancreatic ductal cells, Rac1 inhibition (via inhibitors or siRNA) decreased Claspin protein levels without affecting its mRNA, reflecting a >3-fold reduction in Claspin's half-life. Claspin contains a …

Overcoming Radiation Resistance: Ferroptosis Induction To Sensitize Solid Tumors To Radiation Therapy, Joseph Carmicheal, Caden M. Fritson, Alexandra Seas, Heidi M. Vieira, Surinder K. Batra

Journal Articles: Biochemistry & Molecular Biology

Radiation therapy (RT) is a mainstay of treatment for a myriad of cancers, often utilized for tumors that are unable to be resected, as well as an adjunct to surgery and chemotherapy. Unfortunately, many cancers are resistant to RT-induced damage and subsequent cell death. This has spurred the pursuit of novel radiation sensitizers that could potentiate the effects of this widely used and important treatment modality. Since its discovery as a regulated cell death mechanism in 2012, ferroptosis has been studied for its connection to cancer and other known oxidative pathways. With this, the interplay between RT and ferroptosis in …

Cox, G. Talmon, Paul M. Grandgenett, Michael A. Hollingsworth, Dominick J. Dimaio, Jean L. Grem, Surinder K. Batra, Moorthy P. Ponnusamy

Journal Articles: Biochemistry & Molecular Biology

Pancreatic ductal adenocarcinoma (PDAC) is among the most lethal cancers, with over 83% of patients presenting metastases to vital organs such as the liver, lungs, and peritoneum. Although glycosylation has been established as a critical factor in PDAC development, little is known about the molecular underpinnings of organ-specific metastasis. In this study, we investigated the role of glycosyltransferases (GTs) in mediating PDAC metastatic organotropism. Through an unbiased transcriptomic screen, we identified distinct GT expression patterns in liver- and lung-tropic PDAC cells. Notably, GCNT3 and B3GNT3 were selectively upregulated in liver and lung-tropic cells, respectively. These mutually exclusive expression patterns were …

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Piglet preweaning mortality (PWM) in the United States averages ≈14–15%, with sow overlaying causing about one third proportion of these losses. This research aimed to develop and evaluate deep learning models to classify six sow postures using depth images to monitor behaviors linked to overlaying risk. Top-down depth images were captured with Kinect V2^® cameras at 10 frames min^-1 for five consecutive days (2 days before to 2 days after farrowing), yielding 26,506 training images from 18 sows, 17,901 testing images from 12 sows, and 4,697 additional images from three sows in diagonal stalls for external validation. Three …

We propose a real-time bidirectional translation framework integrating MediaPipe for hand landmark extraction, a Convolutional Neural Network (CNN) classifier built with TensorFlow/Keras for gesture recognition, OpenAI Whisper for robust multilingual speech-to-text transcription, and Google TTS for naturalistic speech synthesis. The system achieves 93% classification accuracy across 35 ISL classes (alphabets A–Z and numerals 1–9) on a dataset of 42,700 images, with macro and weighted F1-scores of 0.93. Deployed as a Flask …

Remember To Say Her Name - Addressing Black Women's Experiences Of Vicarious Police Brutality And Testing A Racial Trauma Meditation, Gabriella A. Roper

College of Graduate Studies: Theses & Dissertations

Black women and girls are disproportionately impacted by police violence, as some are victims of brutality but also as viewers of police violence videos and advocates for police reform (Williams, 2021). Yet, most media coverage centers on police brutality against Black men, rendering the suffering of Black women largely invisible. Studies indicate heightened rates of distress experienced by Black women as a result of race-based stressors, compounded by their limited access to adaptive coping mechanisms (Beauliere, 2022; Hawkins, 2022). This study investigated the psychological effects of vicarious police brutality exposure on Black women. In addition, this study evaluated the effectiveness …

A Quantitative Analysis Of Burrowing And Subterranean Locomotion In The Sand Lance Using A Transparent Sediment, Issei Fujita, Makoto Tomiyasu, Jun Yamamoto, Yasuzumi Fujimori

Journal of Marine Science and Technology–Taiwan

Sand lances (Ammodytes spp.) rely on rapid burrowing into sediment for predator avoidance. Although their sediment grain-size preferences are well documented, the biomechanics underlying burrowing success remain unclear because natural substrates are opaque. Using a transparent-sediment system, we directly visualized and quantified burrowing kinematics to: (1) test the effect of body size (total length, TL) on burrowing success; (2) examine entry mechanisms (e.g., swimming speed, entry angle); and (3) describe locomotion within sediment. Logistic regression on the full dataset (N = 28 fish) identified TL as the primary determinant of success, with larger individuals exhibiting significantly higher success …

Cruise Network Design Under Sequential Duopolistic Entry, Ta-Hui Yang, Ching-Hui Tang, Wan-Tien O

Journal of Marine Science and Technology–Taiwan

This study addresses the network design for international cruise services in a duopolistic market, where carriers enter and make decisions sequentially. The leader, who makes the first move, makes decisions as there is no competitor in the market. The follower, who makes decisions later, has to design their network considering the existing leader’s network. The leader’s model is a mixed integer linear problem while the follower’s model is a mixed integer nonlinear problem. Therefore, a heuristic is proposed to solve the problem. The commercially available general algebraic modeling system is used in conjunction with its different solvers to solve the …

Effect Of Heat Treatment On The Corrosion And Wear Behavior Of 17-4 Ph Stainless Steel For Marine Applications, Syuan Tai, I-Kon Lee, Ming-Yuan Lin, Kang-Yu Liao, Chin-Chun Chang, Hung-Bin Lee

Journal of Marine Science and Technology–Taiwan

This study explores the tribocorrosion behavior of conventionally cast 17-4 PH stainless steel under real seawater conditions, focusing on the effects of three heat treatments (Solution, H900, H1100). Electrochemical tests, tribocorrosion experiments, SEM, XPS, and quantitative analysis were used to establish a three-stage tribocorrosion mechanism. Results show that H900 exhibits superior corrosion and wear resistance, while H1100 suffers increased material loss and surface cracking at high potentials. Elemental analysis revealed NbC migration forming third-body particles, which, although briefly reducing friction, induced local stress concentration and crack initiation. The findings highlight the critical influence of microstructure, passive film stability, and third-body …

Enhancing Underwater Imagery And Organism Detection Using Reinforcement Learning, K. Arul Deepa, P. Ramya, Karpaga Vinodha, Dharmaraja C

Journal of Marine Science and Technology–Taiwan

Underwater environments pose significant challenges in assessing image quality and organism detection due to light scattering and absorption, which limits visibility and color fidelity. Existing solutions often fail to effectively address these challenges, resulting in suboptimal image quality and hindering organism identification. This paper examines the problem through a dual-focused approach: enhancing underwater images and detecting organisms using the Underwater Image Enhancement Benchmark (UIEB) dataset. The first step introduces a state-of-the-art method for image enhancement by applying reinforcement learning (RL) principles. By formulating the enhancement process as a Markov Decision Process (MDP)—where states are represented by image features and actions …
