Lepton Flavor Violating Z And Higgs Boson Decays In Left-Right Models, Mangala Hegde Nagapati

University Departments

In this work, we explore lepton flavour violating (LFV) decays of the Z and Higgs boson in Alternative Left-Right Model that extend the Standard Model field content and gauge structure. The presence of exotic fermions, additional gauge bosons, and charged scalar fields in these scenarios can induce LFV processes through I-loop and mixing effects. We evaluate the 1-loop branching ratios for decays such as Z -t et,e1and h -t etej (i -=t- j), taking into account current experimental constraints on exotic field masses, and flavour-violating observables. A random scan of the model parameters is performed to systematically examine the phenomenology …

Formation Pathways Of Complex Organic Molecules In The Interstellar Medium- A Computational Study, Sharadhi Vakuda

University Departments

Nitrile-substitutedpolycyclic aromatic hydrocarbons (CN-PAHs) are of growing astrochemical interest because they connect aromatic carbon chemistry with the rich nitrile chemistry observed in interstellar environments. Motivated by the recent detection of cyanocoronene (C24H11CN) in Taurus Molecular Cloud- I (TMC-1), this thesis investigates both the possible formation pathways of cyanocoronene and its infrared detectability in astronomical environments. In the first part of the work, several chemically plausible reaction routes were explored using density functional theory (DFT), along with higher-level multireference calculations including CASSCF and NEVPT2 for selected key structures. Geometry optimizations, vibrational frequency calculations, and transition-state searches were carried out to construct …

An Instance Segmentation Based Global Mppt Method For Pv Systems Under Partial Shading Condition, Ehab Ur Rahman, Yousef Mahmoud, Rui Bo

Electrical and Computer Engineering Faculty Research & Creative Works

Partial shading in photovoltaic (PV) systems creates multiple Local Maximum Power Points (LMPPs) on the power-voltage (P-V) curve, causing conventional Maximum Power Point Tracking (MPPT) algorithms to converge prematurely to suboptimal operating points and resulting in significant energy losses. This work proposes a novel vision-based framework that integrates computer vision with Global Maximum Power Point Tracking (GMPPT) to maximize energy harvesting in partially shaded PV systems. The proposed method captures real-time imagery of PV panels to identify cell-level shading patterns, which are subsequently mapped to module electrical characteristics to enable direct analytical estimation of the GMPP voltage. An instance segmentation …

People Who Use Opioids’ Encounters With Criminal Justice Personnel: A Qualitative Analysis, Barbara J. Costello

Sociology and Anthropology Faculty Publications

There is little research in the U.S. on the interactions of people who use opioids (PWUO) with criminal justice personnel, from their perspective. This study reports on the experiences with police and criminal justice personnel of 27 men and women in treatment for substance use disorder. In-depth interviews revealed that many respondents had had aversive experiences with the criminal justice system, including both physical and verbal abuse. Very few report receiving information on treatment from police. The evidence suggests that many police officers do not view opioid use disorder as a medical condition, and instead stigmatize PWUO. This study reveals …

The Geography Of Faces, Faith Abraham

be Still

The Geography of Faces takes its title from the idea that a face, seen across decades, becomes a kind of landscape—something you learn to read not at a glance but through accumulated return visits. For Dr. Vasquez, an older physician who has seen so much, her patients' faces are the territory she has spent a lifetime learning to navigate.

The patients are chosen to represent different dimensions of that longevity. They show affection built on years of small battles, continuity across a family, autonomy that is respected. Together, these patients make the case that primary care is less about problems …

Hiv-1 Tat-Driven Glutamate Dysregulation: Implications For Cognitive Impairment In Hand, Brenna Duffy, Michael Nonnemacher, Sandhya Kortagere

Kimmel Cancer Center Faculty Papers

PURPOSE OF REVIEW: HIV-1-associated neurocognitive disorders (HAND) manifest in 15% to 50% of people with HIV, impairing learning and memory and executive function. The chronic generation of HIV-1 Transactivator of transcription (Tat) likely contributes to HAND via direct neuronal toxicity and glial-mediated toxicity. This review summarizes our current understanding of how chronic Tat generation from microglia and astrocytes promote glutamate excitotoxicity.

RECENT FINDINGS: In recent years, the indirect effects of Tat through the activation of glial cells have gained significant interest. This review highlights microglia and astrocytes as HIV-1 reservoirs that release Tat protein in the central nervous system. Specific …

(Re)Claiming Homeplace: Dance As Embodied Resistance & Healing For Health & Spatial Justice, Preeya G. Kannan

University Honors Theses

This thesis argues that dance functions as both an upstream public health intervention and a form of radical spatial resistance; creating healing, agency, and belonging among historically marginalized communities. Drawing on bell hooks' concept of homeplace, Jasbir Puar's assemblage theory, Nancy Krieger's eco-social theory, and Katherine McKittrick's Black geographies, I position the body as both an ecological and political landscape shaped by histories of colonialism, racial capitalism, displacement, and resilience.

Through this community-based participatory research study, Homeplace, I explore dance as a form of social prescription that centers liberation rather than pathology. Movement is often reduced in public health discourse …

Alustath Journal for Human and Social Sciences

This research paper investigates the use of alliteration and assonance as major sound devices in poetry, concentrating on their stylistic and aesthetic functions in selected poetic texts. Sound patterns such as the repetition of consonant sounds (alliteration) and vowel sounds (assonance) play a vital role in shaping rhythm, musicality, and meaning in poetic language. The study aims to identify these phonological features and analyze how they contribute to the artistic structure and emotional impact of the poems. The research adopts a stylistic and statistical approach, examining the distribution and frequency of alliteration and assonance in two poems: The …

Extending Unibreak: Semantic Retrieval And Harmful-Intent Direction Suppression For Token-Level Llm Jailbreaking, Sanket Saha

Master’s Dissertations

Token-level adversarial perturbations remain one of the most efficient known attacks against the safety alignment of instruction-tuned large language models (LLMs). Among recent works, the UniBreak framework (You et al., 2026) stands out for unifying gradient-based optimization with an evolutionary perturbation repository. However, its repository relies solely on accumulated success frequency without utilizing query content, and its fitness function implicitly assumes that suppressing refusal tokens is sufficient to elicit harmful responses. In this dissertation, we extend UniBreak along both axes and re-evaluates the framework under stricter generalization and judgment protocols. Specifically, we introduce a semantic perturbation repository that replaces frequency-only …

Recently, calcined dredged sediment (CDS) has emerged as a supplementary cementitious material (SCM), offering a viable alternative to traditional SCMs, such as fly ash and slag cement. This review synthesizes current knowledge on the physical, chemical, and mineralogical characteristics of raw DS and pretreatment strategies aimed at dewatering, organic matter removal, and contaminant stabilization. The effects of calcination on the production of reactive amorphous aluminosilicates are also discussed. Emphasis is placed on physicochemical changes revealed by experimental …

Simultaneous Tumor Delineation And Report Generation From Brain Mr Images, Adish Mallik

Master’s Dissertations

Brain tumor analysis is an important application of medical image computing, where accurate segmentation and interpretation of tumor regions can support diagnosis and treatment planning. However, existing methods often address tumor segmentation and radiology report generation as separate tasks. Moreover, one of the major challenges in report generation tasks from MRI is accurate tumor localization. Most models fail to locate the lobe and hemisphere in which the tumor is located, causing incorrect report generation. In this regard, a unified 3D vision-language framework is proposed for simultaneous brain tumor segmentation and report generation from multi-modal MRI. Given T1, T2, T1C, and …

Ontology-Based Decision Support System For Improving Aquaculture Management, Thuy Thi Thu Pham, Phuong Thi Can, Nga Thi Thanh Ha

Journal of Marine Science and Technology–Taiwan

Early detection of shrimp diseases is vital for reducing losses and ensuring sustainable aquaculture. In this study, a novel ontology-driven framework for shrimp disease diagnosis that integrates environmental knowledge with machine learning-based image analysis is proposed. An ontology was constructed from a structured dataset of environmental parameters and farm conditions related to shrimp diseases, which formally represents concepts such as farm characteristics, environmental factors, symptoms, and disease types. Two public shrimp image datasets were subsequently used to train convolutional neural networks (ResNet50 and MobileNetV2) for automated disease classification. The predicted disease labels and confidence scores were mapped onto the ontology. …

Dynamic Governance Of Transboundary Fisheries Through Deep Learning And High-Frequency Vessel Tracking Data For Climate-Resilient Management: An Application To The East China Sea, Qin Lin, Yaqing Shu, Manel Grifoll, Hongxiang Feng

Journal of Marine Science and Technology–Taiwan

Transboundary fisheries governance is increasingly challenged by jurisdictional conflicts, regulatory asymmetries, and climate-induced stock shifts in fish stocks, especially in contested regions like the East China Sea (ECS). This study capitalizes on China’s high-frequency BeiDou Navigation Satellite System (BDS) data (June 2021–May 2022) to pioneer a CNN-BiLSTM deep learning model to dynamically identify fishing hotspots and evaluate policy effectiveness. By integrating vessel trajectories, environmental variables, and regulatory events, we examine spatiotemporal patterns of fishing effort relative to seasonal bans, extreme weather, and quota systems. Key findings reveal: (1) post-moratorium (September–December) concentration of fishing intensity, peaking in November; (2) significant weather-driven …

Lock Scheduling Decisions And Strategy Optimization Under Operation Interruption Scenarios, Junhe Li, Qiang Zhang, Junpeng Jiang, Jiangchao Bao

Journal of Marine Science and Technology–Taiwan

Locks are critical nodes in inland waterway transportation systems that concentrate vessel traffic between upstream and downstream reaches, making their operations highly sensitive to hydrological conditions. Therefore, disruptions caused by droughts, floods, or routine maintenance can easily trigger congestion. To address this issue, this study systematically examines the interrelationships among the number of ships awaiting passage, scheduling strategies, the trade-off between lock chamber utilization and ship waiting time, the influence of ship entry sequences on user satisfaction, and the combined effects of these factors on overall lock scheduling performance. Based on these analyses, an integrated decision-making model for two-stage ship …
