Advancing Brain Tumor Segmentation With Spectral–Spatial Graph Neural Networks, Sina Mohammadi, Mohamed Allali

Engineering Faculty Articles and Research

In the field of brain tumor segmentation, accurately capturing the complexities of tumor sub-regions poses significant challenges. Traditional segmentation methods usually fail to accurately segment tumor subregions. This research introduces a novel solution employing Graph Neural Networks (GNNs), enriched with spectral and spatial insight. In the supervoxel creation phase, we explored methods like VCCS, SLIC, Watershed, Meanshift, and Felzenszwalb–Huttenlocher, evaluating their performance based on homogeneity, moment of inertia, and uniformity in shape and size. After creating supervoxels, we represented 3D MRI images as a graph structure. In this study, we combined Spatial and Spectral GNNs to capture both local and …

The Lowest Discriminant Ideal Of Cayley-Hamilton Hopf Algebras, Zhongkai Mi

LSU Doctoral Dissertations

Discriminant ideals are defined for an algebra R with central subalgebra C and trace tr : R → C. They are indexed by positive integers and more general than discriminants. Usually R is required to be a finite module over C. Unlike the abundace of work on discriminants, there is hardly any literature on discriminant ideals. The levels of discriminant ideals relate to the sums of squares of dimensions of irreducible modules over maximal ideals of C containing these discriminant ideals. We study the lowest level when R is a Cayley-Hamilton Hopf algebra, i.e. C is also a Hopf subalgebra, …

Ethanol-Induced Alterations To Astrocytic Glutamate Transporter Mrna Expression In The Mpfc Of Adult Mice, Zachary Evans

Undergraduate Honors Theses

The medial prefrontal cortex (mPFC) is one of several brain structures that is contained in the mesolimbocortical pathway and controls many processes involved in alcohol use disorder (AUD). There is vast glutamatergic output from the mPFC to other mesolimbocortical regions; neuroplastic changes to this system are believed to be closely tied to the development and maintenance of AUD. Astrocytes are key regulators of glutamatergic transmission through their uptake of excess glutamate from the synapse and recycling back into neurons. Ethanol (EtOH) alters the expression of astrocytic genes that encode for transporters that control glutamate homeostasis; these include the glutamate transporter-1 …

Faculty, Staff and Students Publications

Potassium-competitive acid blockers (P-CABs) provide potent acid inhibition, yet studies on P-CAB-based quadruple therapy for H. pylori eradication are limited. We theorized that integrating bismuth subsalicylate into a quadruple therapy regimen could enhance eradication rates. However, data on the efficacy of vonoprazan bismuth quadruple therapy are notably scarce. Therefore, the aim of this study was to evaluate the efficacy of vonoprazan-based bismuth quadruple therapy in areas with high clarithromycin and levofloxacin resistance. This was a prospective, single-center, randomized trial conducted to compare the efficacy of 7-day and 14-day vonoprazan-based bismuth quadruple therapy for H. pylori eradication between June 1, 2021, …

Family Medicine’S Role In Addressing The Intersections Of Redlining And Climate Change, Daryl O. Traylor, Eboni E. Anderson, Brianna Clark, Alex M. Smith, Cooper K. Allenbrand

Journal of Sustainable Social Impact

Redlining, the practice of discriminating against specific neighborhoods based on race and socioeconomic status, leads to persistent environmental hazards and socioeconomic inequalities that have lasting adverse health effects on their populations. Health disparities are further exacerbated through the concentration of environmental hazards, as well as the escalating impact of climate change, which poses an increased risk of respiratory illness, cardiovascular disease, mental health issues, heat-related illness, infectious diseases, food insecurity, and socioeconomic difficulties in redline neighborhoods.

This paper examines the interplay of redlining, climate change, and health disparities, with an emphasis on the enduring consequences for these marginalized communities. Through …

Radiative Cooling For Energy-Efficient Power Generation, Rickia Hanna

Celebrating Scholarship and Creativity Day (2018-)

This thesis examined radiative cooling on a small scale using a hybrid photovoltaic/radiative cooling model system, to determine its efficiency for large-scale power generation. Radiative cooling is concerned with heat transfer and this thesis’s main goal is to harness that heat energy to produce electricity. The efficiency of the system was tested using various light sources at different angles and total power output. The testing was done several times and there proved to be a proportional relationship between light intensity and current output. However, due to the performance threshold of the PTEC module, the component of the system used to …

Relations Between Prior Racial Microaggressions, Expat Motivation, And Life Satisfaction Among African American Expat Women In Mexico, Patricia Keller

Dissertations

Microaggressions refer to subtle forms of racism that occur in everyday interactions, often conveying hostile or demeaning messages. These experiences can have a negative impact on the psychological well-being and life satisfaction of African Americans. However, there is a lack of research that explores the relationship between microaggressions and the life satisfaction of African American women who have relocated abroad. Additionally, little is known of the contemporary motivations for expatriation of African American women. A review of African American historical migration, study abroad participation, and tourism lays the framework for examining recent expatriation. The purpose of this study was to …

The Chagos Archipelago: A Failure Of International Law To Protect Powerless Peoples, Cali Smith

Cardozo International & Comparative Law Review (CICLR) Blog

The opening act of 2024 featured David Cameron, the United Kingdom’s (UK) latest Foreign Secretary, dashing the hopes of a displaced people; the island natives of the Chagos Archipelago. The Chagos islanders (Chagossians) have waged a decades long battle for the right to return to their homeland, from which they were forcibly removed in the 1960’s and 70’s. The former Foreign Secretary, James Cleverly, indicated that the UK was in negotiation regarding the resettlement of the Chagossians to their native islands. However, on January 9, 2024 Cameron stated that the return of the Chagossians to their islands was “not possible.” …

A Data-Driven Framework To Inform Sustainable Management Of Animal Manure In Rural Agricultural Regions Using Emerging Resource Recovery Technologies, Mohammed T. Zaki, Lewis Stetson Rowles, Jeff Hallowell, Kevin D. Orner

Civil Engineering & Construction: Faculty Publications

Thermochemical conversion technologies are emerging as preferred resource recovery practices for managing animal manure in agricultural regions. Although the implementation of such technologies has been previously studied, difficulties exist in maintaining balance between high rate of resource recovery and low environmental, economic, and social impacts, particularly in rural regions with limited resources. We developed a data-driven framework by integrating machine learning with life cycle thinking that can be used as an open-source tool to help overcome these barriers. The framework was applied to compare two emerging technologies: pyrolysis versus hydrothermal carbonization for managing the excess poultry litter in a rural …
