Investigating The Relationships Among Suspended Sediment Concentration, And Marsh Edge Erosion In Barataria Bay, La, Lily Vowels

LSU Master's Theses

Barataria Bay, Louisiana, USA exhibits a unique microtidal, wind-driven hydrodynamic climate where extensive levee infrastructure throughout Louisiana has starved Barataria Bay and similar interdistributary bays of the historic levels of terrigenous sediment import. This has contributed to extreme coastal wetland loss in Louisiana. This project seeks to understand how hydrodynamic and meteorological conditions are linked to sediments’ fate after erosion from the marsh edge. Specifically, this project seeks to differentiate the roles of wave resuspension and marsh edge erosion (MEE) in sediment dynamics in Barataria Bay. An acoustic wave and current profiler (AWAC) was used to capture hydrodynamic conditions, and …

From Devices To The Cloud: Digital Forensics In The Changing Social Media Landscape, Joseph Brown

LSU Master's Theses

This thesis presents a comprehensive digital forensic analysis of emerging and alternative social media platforms, including Truth Social, Threads, Bluesky, Nextdoor, and Neighbors. These platforms, which range from politically aligned alt-tech networks to hyperlocal neighborhood apps, present unique forensic challenges and security vulnerabilities. Across all case studies, established forensic techniques were applied using a hybrid methodology combining mobile device analysis, network traffic monitoring, and API interrogation. Findings include the discovery of plaintext credentials, session tokens, and other sensitive artifacts, particularly in platforms with weaker security postures such as Truth Social, Bluesky, Nextdoor, and Neighbors. Threads, by contrast, demonstrated greater resilience …

Conditional Optimal Sets And The Quantization Coefficients For Some Uniform Distributions, Evans Nyanney, Megha Pandey, Mrinal Kanti Roychowdhury

School of Mathematical & Statistical Sciences Faculty Publications

Bucklew and Wise (1982) showed that the quantization dimension of an absolutely continuous probability measure on a given Euclidean space is constant and equals the Euclidean dimension of the space, and the quantization coefficient exists as a finite positive number. By giving different examples, in this paper, we have shown that the quantization coefficients for absolutely continuous probability measures defined on the same Euclidean space can be different. We have taken uniform distribution as a prototype of an absolutely continuous probability measure. In addition, we have also calculated the conditional optimal sets of n-points and the nth conditional quantization errors …

Cloud-Assisted Multi-Channel Data Broadcasting, Debabrata Maji

Master’s Dissertations

The convergence of Internet of Things (IoT) and cloud computing has transformed technology, impacting commerce, industrial production, data management, etc. Multi- Channel Broadcast Encryption (MCBE), first introduced by Phan et al. (ASIACCS 2013), is a cryptographic encryption primitive used for both IoT and Cloud that permits a sender to e!ciently and securely encrypt several messages for di”erent groups of receivers. After thoroughly exploring the existing literature, we observe that none achieves the robust provable security within the standard model. This paper addresses this gap, aiming to achieve adaptive INDistinguishable under full-IDentity Chosen-Ciphertext Attack (IND-ID-CCA) security by constructing an e!cient identity-based …

Association Between Homelessness And Maternal Health Outcomes Among Non-Hispanic Black Women In Georgia, Miranda Weaver

Walden Dissertations and Doctoral Studies

Maternal health disparities among homeless non-Hispanic Black women in Georgia represent a critical public health concern, driven by inequitable access to care and elevated risks of adverse pregnancy outcomes. This study examined how homelessness influences perinatal care utilization (timing and frequency of prenatal visits and postpartum checkups) and pregnancy complications (gestational diabetes, hypertension, and depression), and whether these associations differ by geographic context (urban versus rural). Grounded in the Social Determinants of Health framework, the study used a quantitative cross-sectional design, analyzing secondary data (n = 1,540; weighted ≈ 203,571) from Phase 8 (2017–2021) of the Pregnancy Risk Assessment Monitoring …

The Influence Of Sociodemographic Factors On Opioid Mortalities In The U.S. State Of Georgia, Theresa Highsmith

Walden Dissertations and Doctoral Studies

Since the late 1990s, the United States has been in the midst of an opioid epidemic that continues to present significant public health challenges. Opioid-related mortality, particularly involving fentanyl, has disproportionately affected vulnerable populations. The purpose of this quantitative study was to examine the associations between educational level, homelessness, and alcohol use with opioid-related overdose deaths involving fentanyl, while controlling for age, gender, and marital status, among Black and White populations in the U.S. state of Georgia. The theoretical framework was Bronfenbrenner’s socioecological model, which recognizes that individual behavior is influenced by multiple levels of factors, including interpersonal, community, and …

Comparing Dosimetric Outcomes Of Static Imrt And Vmat In Accelerated Partial Breast Irradiation For Medially Located, Left-Sided Tumor Beds, Rani Jamil

Masters Projects

Abstract

Introduction: Accelerated partial breast irradiation (APBI) has emerged as a targeted alternative to whole-breast irradiation for early-stage breast cancer, particularly for patients with medially located, left-sided tumors. Static intensity-modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) offer advanced dose conformity, yet no direct comparisons between static IMRT and VMAT have been conducted specifically for medially located, left-sided APBI, a uniquely challenging anatomical subgroup. This study evaluates dosimetric differences between static IMRT and VMAT plans to determine which modality provides superior target coverage and organ-at-risk (OAR) sparing in left-sided APBI.

Methods: Ten patients with medially located left-sided breast …

Shock Induced Droplet Aerobreakup For Newtonian And Non-Newtonian Fluids, James Leung

LSU Doctoral Dissertations

This research investigates shock-induced aerodynamic breakup (aerobreakup) of fluids with different stress-strain behaviors. The central hypothesis is that shear stress from highspeed gas flow manifests differently depending on a fluid’s strain response, influencing droplet breakup morphology, fragment size distribution, and drag-induced acceleration. To test this, experiments and simulations were performed on μm–mm sized droplets of Newtonian (water) and shear-thinning fluids (nanofluids or xanthan gum). Two experimental setups were used: an open-ended shock tube and a closed conventional shock tube. In the openended setup, a normal shock impacts a stationary droplet held by an acoustic levitator. Droplet breakup and gas dynamics …

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

We tested if hyperoxic conditions can reduce the proportion of active myofibroblasts, which are assumed to be a major driver of head and neck radiation-induced fibrosis, as measured by expression levels of pro-fibrotic genes. Radiated, non-cancerous soft tissue from the head and neck and skin/soft tissue from non-radiated flap donor site were collected from each patient. Myofibroblast density was quantified using immunofluorescence staining with α-SMA and DAPI and visualisation under confocal microscopy and compared between baseline non-radiated and radiated tissue from the same patient. From each tissue specimen, fibroblast cell lines were cultured and exposed to either normoxic, hypoxic, or …

The Microtubule-Severing Enzyme Spastin Regulates Spindle Dynamics To Promote Chromosome Segregation In Trypanosoma Brucei, Thiago Souza Onofre, Qing Zhou, Ziyin Li

Faculty, Staff and Student Publications

Microtubule-severing enzymes play essential roles in diverse cellular processes, including mitosis and cytokinesis, by modulating microtubule dynamics. In the early branching Trypanosoma brucei, microtubule-severing enzymes are involved in cytokinesis and flagellum length control, but none of them have been found to regulate mitosis. Here we report the characterization of the microtubule-severing enzyme spastin in the procyclic form of T. brucei. We demonstrate that spastin severs microtubule in vitro and overexpression of spastin disrupts spindle microtubules in vivo in trypanosomes, leading to defective chromosome segregation. Knockdown of spastin impairs spindle integrity and disrupts chromosome alignment and segregation. We further show that …

Ai Regulation: Competition, Arbitrage & Regulatory Capture, Filippo Lancieri, Laura Edelson, Stefan Bechtold

Georgetown Law Faculty Publications and Other Works

The commercial launch of ChatGPT in November 2022 and the fast development of large language models have catapulted the regulation of artificial intelligence to the forefront of policy debates. A vast body of scholarship, white papers, and other policy analyses followed, outlining ideal regulatory regimes for AI. The European Union and other jurisdictions have moved forward by regulating AI and LLMs. One overlooked area is the political economy of these regulatory initiatives—or how countries and companies can behave strategically and use different regulatory levers to protect their interests in the international competition on how to regulate AI.

Story Forge: A Card-Based Framework For Ai-Assisted Interactive Storytelling, Yaojiong Yu, Gianni Corino, Mike Phillips

School of Art, Design and Architecture

The application of artificial intelligence has significantly advanced interactive storytelling. However, current research has predominantly concentrated on the content generation capabilities of AI, primarily following a one-way ‘input-direct generation’ model. This has led to limited practicality in AI story writing, mainly due to the absence of investigations into user-driven creative processes. Consequently, users often perceive AI-generated suggestions as unhelpful and unsatisfactory. This study introduces a novel creative tool named Story Forge, which incorporates a card-based interactive narrative approach. By utilizing interactive story element cards, the tool facilitates the integration of narrative components with artificial intelligence-generated content to establish an interactive …

Sbv_Dps: A Stacking-Bagging-Voting Nested Ensemble Based Diabetes Prediction System Using K-Fold Cross Validation, Sourabh Shastri, Sachin Kumar, Paramjit Kour, Vibhakar Mansotra

Mansoura Engineering Journal

With the advancement of machine learning techniques, the introduction of the most accurate model has become a necessity. In real-world scenarios, every model has some constraints and assimilates errors, so their performance is not always highly efficient; this sparked the development of ensemble learning. The ensemble approach aims to consolidate the strengths of existing approaches and minimize their weaknesses or decision-making risks. The proposed diabetes prediction system encases a resampling filter, applied to balance the dataset and model builder method, i.e., without the SBV ensemble and with the SBV ensemble method. The model is initially built without using the SBV …

Faculty Publications

Objectives

Movement behaviors, such as sedentary behavior (SB), light intensity physical activity (LPA), and moderate to vigorous intensity physical activity (MVPA) are mutually exclusive, in that time spent in one behavior inevitably displaces time spent in another. Yet, few studies have simultaneously considered these health behaviors and their association with health-related quality of life (HRQoL), an important indicator of health and well-being in aging populations. This study aimed to explore the role of waking movement behaviors (i.e., SB, LPA, MVPA) in prospectively predicting HRQoL in older adults. The study further aimed to cross-validate associations between movement behaviors and HRQoL using …

Rishon Le-ẒIyyon, Winepress Park: Geomorphology And Sedimentology, Joel Roskin, Yotam Asscher

Qadum: Journal of Excavation Reports from Israel

An extensive brown sandy double-unit sediment, draping large parts of the archaeological remains at the Winepress Park in Rishon Le-Ẓiyyon, is suggested to be associated with the previously reported, undated ʻEn Ha-Qore clay. Based on relative age port-OSL profiling, the depositional mechanism of this unit and the overlying sand is suggested to be related to late Holocene, dune-dammed winter ponds. These aeolian-fluvial dune-damming processes may have been partly triggered by intensive Byzantine human activity that may have led to sand mobilization.

Humanization Strategy Of The Public Urban Space In Cairo, Rania Badawy Shokry

Mansoura Engineering Journal

An accurate scientific definition of the term “humanization of cities” has not yet crystallized, which refers the term to the word from which it is derived. She is "human". Obviously, anything contrary to it is inhuman; starting from wild nature or a life entirely dependent on vehicles. If a person cannot dispense with vehicles when carrying out his daily activities, then here we know that the standard of humanization in a place is low. However, if the planning of a city or neighborhood takes into account the needs of the population and the human standard, then the city may reach …
