Exploring Longitudinal Stability Of Spatiotemporal Sequential Patterns By Means Of Autoencoder Schemes For Eeg Based Personal Identification, Muhammed E. Oztemel Aug 2025

Exploring Longitudinal Stability Of Spatiotemporal Sequential Patterns By Means Of Autoencoder Schemes For Eeg Based Personal Identification, Muhammed E. Oztemel

LSU Doctoral Dissertations

Robust personal identification remains a critical and challenging task in the digital era. Electroencephalography (EEG) offers a unique biometric modality that captures individual brain dynamics through complex neural signals. This dissertation proposes autoencoder (AE) based feature extraction and subject identification through these features. EEG recordings are first transformed into topographic maps to represent spatial brain activity. Consecutive topomaps are then concatenated to capture temporal transitions across frames. Convolutional autoencoders (CAEs) are used to learn spatial and temporal patterns, while domain-adaptive AEs are designed to model evoked potential based responses. Additionally, self-attention mechanism is incorporated to enhance feature representation. To analyze …

Development Of Low-Profile Wideband Microstrip Antennas For Cubesat Phased-Array Applications, Mitchell R. Hay Aug 2025

Development Of Low-Profile Wideband Microstrip Antennas For Cubesat Phased-Array Applications, Mitchell R. Hay

Engineering

CubeSat missions rely heavily on effective communication systems in order to transmit and receive large amounts of data quickly and efficiently. The total throughput is limited by the capacity of the channel - a quantity dependent upon the signal quality and bandwidth of the link. Volume and power constraints on a CubeSat impede overall capacity in a fixed bandwidth channel. Phased-array antennas provide a more power efficient solution to improving signal quality by optimizing the spatial properties of the link, rather than broadcasting higher signal power over a broader area through power amplification alone. In order to take advantage of …

Reanalysis And (Near) Real-Time Inversion Of Deformation Observations At Alaskan Volcanoes, Mario Fernando Angarita Vargas

Geosciences

Forecasting volcanic eruptions remains challenging due to the complexity and limited understand­ing of volcanic processes. However, recent studies have shown that integrating multidisciplinary data from past eruptions can improve forecasts for monitored volcanoes. The PREEVENTS project addresses this challenge identifying patterns prior, during or following volcanic eruptions on mul­tidisciplinary data. The project considers four disciplines: Geodesy, Petrology, Seismology and Gas/Geochemistry. This dissertation contributes with two novel tools to analyze geodetic data. The first tool exploits the amplitude from SAR imagery to quantify morphology changes during erup­tions. The tool has been verified with a synthetic case and validated with a dome …

Uncovering The Hidden High School Experiences Of Asian American Young Adults: A Mixed Methods Approach, Julia Shin Aug 2025

Uncovering The Hidden High School Experiences Of Asian American Young Adults: A Mixed Methods Approach, Julia Shin

Educational Specialist, 2020-current

Most research regarding Asian American adolescents’ high school experiences have been quantitative in nature, leaving out the nuances of their lived experiences. While quantitative data is important to gather measurable, objective data from a larger sample of people, qualitative data is also important to add depth and humanness to participant responses. Thirty-two Asian American young adults participated in a mixed methods study that consisted of a survey and optional focus group, aiming to explore the impact of the internalization of the model minority stereotype (MMS), ethnic identity, and representation of racially and ethnically minoritized teachers on their high school experiences. …

Considering Climate Contexts: Examining Promotive And Punitive School Characteristics Among Diverse High School Students, Ashley Bazin, Maryse Richards, Akila Raoul, Allison Lloyd, Elizabeth Rovegno, Yael Granot

Psychology: Faculty Publications

Schools are a critical developmental context for adolescents that can, depending on certain characteristics, do a better or worse job at promoting student resilience and well- being. In working to meet student needs and respond to student behaviors, schools can exhibit more punitive characteristics, like exclusionary discipline practices, or more promotive characteristics, including restorative practices and marshaling of mental health resources. While punitive factors have been associated with more negative outcomes, especially for marginalized students, and promotive factors have been associated with more positive outcomes for students, these factors have rarely been considered together. We conducted an online survey of …

Testing An In-Person Segmentation Approach To Enhance Conservation Partnerships Between Agencies And Private Landowners, Jared Messick, Christopher Serenari Dr., Jenn L. Idema, Kristy L. Daniel Aug 2025

Testing An In-Person Segmentation Approach To Enhance Conservation Partnerships Between Agencies And Private Landowners, Jared Messick, Christopher Serenari Dr., Jenn L. Idema, Kristy L. Daniel

Journal of Extension

Creating partnerships with private landowners will require agencies to identify and remove barriers to solidarity through targeted approaches to social interactions. This study provides a heuristic to segment landowners according to the decision-making the level of shared responsibility they associate with conservation outcomes on private lands. I segmented landowners at Texas Parks and Wildlife Department workshops and conducted interviews with participants to better understand the outcomes of the segmentation event. The results of the case study revealed that the segmentation heuristic effectively distinguishes between landowner types and that value alignment with landowners can supplement perceptions of interdependence.

Mathematics, Physics, and Computer Science Faculty Articles and Research

Hydroclimatic whiplash rapid shifts between drought and flood poses growing risks to U.S. communities. Here, we assess historical extremes and future projections using a normalized streamflow metric: the annual mean flow’s deviation from the 1981–2020 average, expressed as a fraction of that average. This metric is applied to United States Geological Survey records and Localized Constructed Analogs downscaled projections under Representative Concentration Pathways 4.5 and 8.5. Results reveal sharp regional disparities, with drought deficits exceeding 300% of normal flow during multi-year droughts. By linking hydrologic outcomes with the Federal Emergency Management Agency’s National Risk Index, we find that counties facing …

Receiver Function Imaging Of The Mantle Transition Zone Beneath The East Sayan Mountains And Adjacent Area In Central Asia: Implications For Lithospheric Drip And Intraplate Cenozoic Volcanism, Yangyang Liao, Kelly H. Liu, Stephen S. Gao

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

To provide constraints on the formation mechanisms of intracontinental volcanisms and intriguing lithospheric thickness variations in the East Sayan Mountains and surrounding areas, we stack P-to-s receiver functions to image the 410-km and 660-km discontinuities. Mantle transition zone (MTZ) thickening observed in a continuous area is attributable to ancient slab remnants, and Cenozoic volcanisms in the peripheral area can be explained by slab dehydration. The thinning of the MTZ in the Tuva-Mongolian Massif can be explained by mantle upwelling branches induced by slab subduction. Our results reveal an approximately circular area in the MTZ that is significantly thicker than usual, …

Modeling The Effects Of Cyclical Masticatory Forces In A 3d Oral Mucosal Model In Vitro, Samantha Robins, Vehid Salih, Alastair Lomax, Sian Crow, Zoe Brookes, Andrew Foey, Simon A. Whawell

Peninsula Dental School

This study describes the development of a three-dimensional (3D) oral mucosal model (OMM) to investigate how oral tissues respond to masticatory forces. The OMMs replicated key features of human oral mucosa, such as stratified keratinocyte telomerase-immortalized gingival keratinocytes (TIGK) layers and fibroblast-populated collagen matrices. Cyclical mechanical forces (0-10 N) for 2 h applied to the model caused force-dependent changes in the histological structure, including thinning of the epithelium and collagen matrix and cell displacement at higher forces. Lactate dehydrogenase (LDH) cytotoxicity assays revealed that 10 N forces led to significant cell damage (about 50% cell death) in TIGK monolayers, whereas …

Bovine Neutrophil Migration, Cd11a/Cd18 Expression, And Cytokine Response To Co-Culture With Mammary Gland Endothelial Cells And Epithelial Cells, David J. Mcclenahan

Faculty Publications

Movement of leukocytes from the circulatory system into a site of inflammation is a highly complex process. The migration of neutrophils into the lumen of the mammary gland during mastitis is no exception. There is information about the involvement of bacterial-produced products during this process, but less is known regarding the role of host products. Two bovine cell lines, a primary mammary gland endothelial cell line and an immortalized bovine mammary gland epithelial cell line (Mac-T), along with freshly isolated bovine neutrophils, were used to study this further. The cell lines were grown on inserts and in wells of tissue-culture …
