Ms-Gator: Multi-Scale Graph Attention With Topological Reasoning For Segmentation And Classification Of Prostate Cancer Based On Gleason Scores Using Histopathology Images, Sujata Patil, Mahadeva Swamy, Kavitha Sooda, Rajanikanth Vadigepalli, Khalid Nazim Abdul Sattar, Md Rafeeq

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Prostate cancer is one of the prevalent and potentially fatal malignancies, affecting men globally. Accurate segmentation and classification of prostate cancer in histopathology images remain challenging due to complex tissue architecture, staining variability, and high inter-observer differences in manual diagnosis. To address these challenges, this research proposes a Multi-Scale Graph Attention with Topological Reasoning (MS-GATOR) for segmentation and classification of prostate cancer based on Gleason Scores (GS). The MS-GATOR incorporates topological reasoning with hierarchical biological structures by constructing a graph-based representation among three spatial scales such as nuclei, glands, and tissues using Delaunay triangulation to capture both geometric and photometric …

Examination Of The Hiring Process: Bias In Selection, Conor Johanson

Honors Theses

Racial discrimination in the hiring process remains a persistent problem despite decades of anti-discrimination legislation and widespread bias-awareness training. The present study examined whether resume quality and candidate race jointly influence hiring evaluations among human resource professionals, a population with formal training in equitable selection practices. Using a 2 × 2 between-subjects design, 129 HR professionals recruited through Prolific were randomly assigned to evaluate a high- or low-quality resume attributed to either a Black or White candidate. Participant evaluations were assessed across warmth-related and competence-related dimensions derived from the Stereotype Content Model, with Aversive Racism Theory guiding predictions about when …

Tracing Microplastics From Polymer-Coated Urea: Urban To Agricultural Pathways And Environmental Fate, Caden Joseph Seely

Theses and Dissertations

Polymer-coated urea (PCU) is widely used as a slow-release nitrogen (N) fertilizer because it improves N use efficiency and reduces losses through leaching, denitrification, and volatilization. However, the polymer coating raises concerns about potential microplastic (MP) transport to surface waters following fertilizer application. This thesis evaluates the off-site transport of MPs and associated nutrient and sediment losses from PCU in both urban landscape and agricultural systems. In the urban landscape study, treatments included sod, mulched beds, and water-efficient ground cover receiving uncoated urea, PCU, or liquid slow-release N at 225 kg N ha⁻¹ (with reduced rates for beds and ground …

Bremsstrahlung Photons Emissions Measured At Different Rf Power In 28 Ghz Ecr Ion Source, Mwingereza John Kumwenda

Tanzania Journal of Engineering and Technology (TJET)

The Texture Of A Threat: Adversarial Training, Cnns, And Obfuscated Malware Detection, Kaelyn Haynie

Senior Honors Theses

Accurately detecting malicious programs is an expanding field of research for machine learning (ML), with a novel approach incorporating a bytecode-to-image pipeline that produces images representative of software. These images are provided to convolutional neural networks (CNNs) to be examined for malicious pattern indicators. However, CNNs struggle to generalize these patterns effectively while still being robust against adversarial data, an issue which this research addresses with adversarial training. In this paper, three unique CNN architectures (a DBFS-MC-inspired baseline, MIRACLE, and PSP-CNN) are trained for binary classification with 15,000 benign and malicious software samples encoded into images for Android, Windows, and …

Prompt Engineering For Lawyers: How Deep The Rabbit Hole Goes: The Chunking Technique And Few Shot Prompting, Cliff Mckinney

Arkansas Law Notes

There are many different strategies and techniques that can be applied to prompt engineering. However, there are six methods that are particularly useful for lawyers: Chunking, which involves dividing a large task into smaller, more manageable requests; Few-shot prompting, which involves giving artificial intelligence examples to guide a response; Iterative prompt refinement, which involves repeatedly rephrasing or refining questions to lead to a better response; Prompt chaining, which involves guiding the artificial intelligence through related multi-step reasoning; Flipped interaction prompting, which involves asking the artificial intelligence to ask the user questions to prompt new thoughts, like the Socratic method; and …

Glossip’S Road Map To Nowhere, Vida Johnson

Georgetown Law Faculty Publications and Other Works

The Supreme Court’s 2025 decision in Glossip v. Oklahoma was heralded as a victory for the defense. This essay argues that the 2025 Glossip decision does little to fix the myriad problems that led to Mr. Glossip’s wrongful conviction. While ultimately the Supreme Court reached the correct outcome this time, the ordinary judicial process and its purported safeguards were not what saved Mr. Glossip’s life. Rather, it was random chance that came to Mr. Glossip’s aid.

Ten years earlier, the Supreme Court, with many of the same Justices on the bench now, paved the way for Mr. Glossip’s execution. The …

Leveraging Convolutional Neural Networks For Through-The-Wall Radar Imaging: Challenges, Impacts, And Future Directions, Tumaini Edgar, Abdulla F. Ally, Abdi T. Abdalla

Tanzania Journal of Engineering and Technology (TJET)

Through-the-wall radar imaging (TWRI) is an essential technology for military and rescue applications; however, its performance in detecting and visualizing high-quality images of targets behind walls is significantly degraded by multipath reflections and signal attenuation. This paper reviews the current state of TWRI and its challenges, and explores the transformative potential of deep learning, particularly convolutional neural networks (CNNs), in addressing these challenges. Peer-reviewed articles published from 2018 to 2024 were analysed to examine CNN applications in addressing TWRI challenges. The analysis reveals that using CNNs, TWRI systems can be more effective by filtering wall distortions, reducing noise, lowering computational …

A Review Of Energy Storage Technologies With Hydro Energy System Design For Off-Grid Electricity, Daniel H. Ngoma, Banet L. Masenga

Tanzania Journal of Engineering and Technology (TJET)

Many renewable energy sources such hydropower—particularly small-scale run-of-river and micro-hydro—offers reliable, low-cost generation. However, their inherent intermittency (due to seasonal flow variations) and inability to instantly match demand necessitate integrated energy storage to ensure a stable, continuous power supply. This review synthesizes contemporary energy storage technologies in the context of their integration with off-grid hydro energy system design.

The study examine a spectrum of storage solutions, evaluating their technical characteristics, costs, and suitability for hybrid hydro applications. Pumped Hydro Storage (PHS), while highly efficient and large-scale, is often geographically constrained and capital-intensive for small off-grid projects. Battery Energy Storage Systems …

Health Awareness And Relative Energy Deficiency In Ultra-Endurance Female Athletes, Myshel Rodenbeck

Doctorate in Kinesiology

Ultra-endurance (UE) participation among female athletes has increased substantially, yet research examining health awareness and physiological risk in this population remains limited. Excessive training combined with inadequate energy intake places ultra-endurance female athletes at elevated risk for the Female Athlete Triad (FAT) and Relative Energy Deficiency in Sport (RED-S), both driven primarily by chronic low energy availability (LEA) and associated with menstrual dysfunction, impaired bone health, metabolic disturbances, and reduced performance.

This mixed-methods, cross-sectional study examined awareness of overall health, fueling behaviors, menstrual health, and recognition of FAT and RED-S among ultra-endurance female athletes over 25 years of age. Participants …

Our Stories: Black Parents’ Experiences At K-12 Predominantly White Institutions, Jason Thompson

Dissertations

Black parents of Black children attending K–12 predominantly White institutions (PWIs) often experience stress as they navigate school environments where they may be perceived as uninterested, combative, or “token” members of the school community. These deficit-based perceptions can cause Black parents to limit school interactions, question whether their perspectives will be valued, and develop distrust toward school personnel. Although research has examined Black students’ experiences in PWIs, fewer qualitative studies have centered on Black parents’ stories. Capturing these experiences in parents’ own words helps challenge harmful stereotypes and offers schools, especially school counselors, deeper insight into strengthening relationships with Black …

Developmental Underpinnings Of The Other Race Effect Using Fmri, Aquilla Denise Copeland

Electronic Theses and Dissertations 2020 - Present

It is well established that perceptual experience with own-race faces is associated with faster and more accurate recognition of own-race compared to other-race faces — a phenomenon known as the other-race effect (ORE). Previous fMRI research has shown that adults generally exhibit more robust face-sensitive responses than children in the core face-processing areas, especially to own-race versus other-race faces. Although much is known about the neural underpinnings of the ORE in adults, little is known about this phenomenon in children. The present experiment aimed to examine face-sensitive fusiform and occipital regions in 8- to 10-year-olds and adults as they engaged …

Toward A Horizonal "I": The Infinite Subject In William Wordsworth's The Prelude, Gabriella Lee Schwartz

Theses and Dissertations

In an 1805 letter to Sir George Beaumont describing his autobiographical poem The Prelude, William Wordsworth remarked that it was "a thing unprecedented in literary history that a man should talk so much about himself." Since then, critics have only affirmed Wordsworth's reputation as a poet, if not the poet, of selfhood and consciousness. Perhaps the most renowned scholarship on Wordsworthian subjectivity was produced by the so-called "Yale School" of the late twentieth century, as J. Hillis Miller, Harold Bloom, Geoffrey Hartman, and Paul de Man all published influential works on the topic. The latter two staked out stances on …
