Bubble continuous positive airway pressure (bCPAP) is a minimally invasive respiratory support for neonates experiencing respiratory distress syndrome (RDS). It exerts continuous, oscillatory air pressure to encourage lung function and development. Neonates’ movement may cause disconnections at the nasal interface. These disconnections are characterized by the cessation of bubbling at the bCPAP respiratory circuit output and frequently go unnoticed until hypoxia develops. Common Neonatal Intensive Care Unit (NICU) bCPAP systems lack a built-in alarm or accessory device to monitor for disconnections. As a result, nursing personnel must exercise extreme caution utilizing current bCPAP procedure. If a neonate is disconnected, it …

Machine Leaming-Empowered Mode Selection For Qos Improvement In D2d-Assisted Communication Networks, Noordin Kamarul Ariffin, Dimyati Kaharudin, Hanafi Effariza, Noman Hafiz Muhammad Fahad, Mohd Ridzuan Nuha Adiba

Research Publications (2021 to 2025)

Device-to-device (D2D) communication has the potential to enhance network efficiency in upcoming sixthgeneration (6G) wireless networks by enabling direct communication between users. However, in ultra-dense network environments, severe interference can degrade D2D performance, potentially leading to suboptimal Quality of Service (QoS) for some users. To address this challenge, we propose a machine learning-based approach for dynamic mode selection between D2D and cellular communication, aiming to improve network efficiency and ensure optimal user satisfaction. The proposed framework leverages clustering algorithms, including k-means and k-medoids, to segregate users based on channel gain, Signal-to-Interference-plus-Noise Ratio (SINR), and path loss. Furthermore, we employ binary …

Religious Freedom As Freedom, Helen M. Alvaré

BYU Law Review

In recent decades, the exercise of religious freedom is increasingly associated with oppression. This is not only due to the disagreement between religions and some governments concerning sexual expression matters—contraception, abortion, same-sex relations, and transgender identity—but is also due to diverging convictions about the substance and sources of freedom. This Article will examine a current and highly visible set of convictions about the contents of human freedom, which together suggest that a thriving religious witness threatens freedom itself. These convictions often surface in the context of laws touching upon sexual expression. It will then contrast these convictions with those found …

Subseafloor in situ temperatures in a drilled hole in the Anhydros Basin, Aegean Sea, measured during International Ocean Discovery Program (IODP) Expedition 398, yielded a low heat flow (<0.023 W/m²) despite active magmatism and rifting in the region. The coldest and highest temperatures were 13.9°C at 52.5 m below seafloor (mbsf) and 15.5°C for the deepest measurement at 360.4 mbsf, respectively. Comparison of a heat transfer model with measurements suggests that sea bottom temperatures during the last glacial period were up to 10°C cooler than Holocene temperatures. The magnitude of Holocene warming co-varies with the geothermal heat flow: if …

Porous cranial lesions (cribra cranii and cribra orbitalia) are widely used by archaeologists as skeletal markers of poor child health. However, their use has not been validated with systematic data from contemporary populations, where there has been little evidence of these lesions or their health relevance. Using 375 in vivo computed tomography scans from a cohort-representative sample of adults aged 40+ years from the Bolivian Amazon, among food-limited, high-mortality forager-farmers, we identified cribra cranii on 46 (12.3%) and cribra orbitalia on 23 (6%). Cribra orbitalia was associated with several hallmarks of compromised immune function, including fewer B cells, fewer naïve …

Psychological Flexibility As A Mechanism Of Change In Online Act Among Adults Living With Chronic Health Conditions, Francesca M. Knudsen, Marissa L. Donahue, Korena S. Klimczak, Ty B. Aller, Michael E. Levin

Psychology Faculty Publications

Living with a chronic health condition (CHC) can negatively impact quality of life (QoL) through a complex interaction of mental health challenges, functional limitations, and disease management demands. Acceptance and Commitment Therapy (ACT) is a transdiagnostic approach that shows promise in addressing shared challenges across various CHCs by fostering psychological flexibility (PF). PF has been associated with improved QoL and functional outcomes and reduced psychological symptoms in individuals living with specific CHCs; yet its mediating role in these outcomes remains underexplored. This secondary analysis examined whether changes in PF mediated improvements in QoL, psychological symptoms, and functional impairment among individuals …

Correctional Psychology And Training Implications: A Mixed Analysis Of Trainee Knowledge And Application Of Ethical Dilemmas In Corrections, And A Closer Look At The Experience Of Support From Generalist Training, Alyssa A. Hoyt

Electronic Theses and Dissertations Archive

Correctional psychology, a subfield of psychology, has long been comprised of its own distinct purpose, focus, and competencies. Yet correctional psychology remains unrecognized today as a formal American Psychology Association (APA) specialization. Unlike forensic psychology, without an APA specialization, and subsequent structured training standards, scholars have argued that correctional mental health professionals may be ill-prepared to navigate unique ethical dilemmas inherent to the correctional environment. The present mixed analysis study aimed to contribute to this discussion by assessing psychology trainees’ ability to respond to hypothetical ethical dilemmas in a manner consistent with correctional environments, and whether prior correctional experience/ exposure …

Calibration Of Detectors For The Tomographic Ionized-Carbon Mapping Experiment, Tessalie A. Caze-Cortes

Theses

Observations of the intensity of the sky at millimeter (mm) wavelengths require accurate calibrations for the spectrometers to work with radio telescopes. However, calibrating is a complex and lengthy process for sensitive detectors that catch single photons. To improve efficiency in locating defective detectors and optimizing bias current, my research involves taking data from previous lab characterizations and creating an algorithm that analyzes and plots the code of all 1920 detectors. This thesis will discuss the importance of mm-wavelength intensity mapping and the questions the TIME research team aims to address. Also, a detailed description of mechanical and computational components …

The People's Rivers: Early Environmental Regulation And The Oregon State Sanitary Authority, Avery Morgan Fischer

Dissertations and Theses

The environmental movement in Oregon can trace its origins to the turn of the twentieth century, where citizen activism and initiative led to the creation of an early environmental regulatory agency, the Oregon State Sanitary Authority. This creation established that the State of Oregon had a duty to preserve, not just the navigability or usability of rivers and waterways, but the quality and purity of its water. The Oregon State Sanitary Authority played an active role in maintaining and protecting the environment as a mandate of the people, and throughout its thirty-year existence battling industrial polluters, reluctant municipalities, and disinterested …

'There Is That Of God In All Of Us': Church, State, And Restrictive Abortion Policies, Kimsey J. Stewart

LSU Master's Theses

Unsafe abortion affects millions of women around the globe every year. Unsafe abortions are more likely to occur in countries with restrictive abortion policies. Yet, these policies persist, and the worldwide trend of liberalization of abortion laws is at risk of reversal. There is a disconcerting lack of research regarding what factors cause governments to enact, retain, and enforce restrictive abortion policies. This paper is an attempt to fill in such a gap. I theorize that countries in which the government has closer ties with religious organizations will have more restrictive abortion policies. My results indicate that this is likely …

Maternal Hyperleptinemia Alters Placental Transcriptome And Progesterone Regulation Without Affecting Early Equine Fetal Growth, Lucinda L. Thorburn

LSU Master's Theses

While consequences of equine obesity are well defined, the extent to which persistent hyperleptinemia and accompanying leptin (Lep) resistance affect the fetal-maternal environment warrants further exploration. This study compared endocrine, fetal, placental, and uterine parameters during early pregnancy (through day 70) in mares with elevated leptin versus normal leptin (NL) concentrations. Fourteen mares were classified as either NL (n = 6; Lep 0.9 ± 0.3 ng/mL), moderate leptin (ML; n = 4; Lep 3.0 ± 0.3 ng/mL), or high leptin (HL; n = 4; Lep 5.8 ± 0.7 ng/mL) based on annual plasma leptin. Mares were artificially inseminated and induced …

Dose Characterization Of Galactic Cosmic Rays In The Human Brain: A Phits-Based Study With A Segmented Anatomical Phantom, Shanice N. Manning

LSU Master's Theses

Astronauts aboard the International Space Station (ISS) are chronically exposed to a complex space radiation environment composed of galactic cosmic rays (GCR), solar particles, and Earth's trapped radiation. These high-energy particles interact with spacecraft shielding, producing secondary particles that can penetrate inside and deposit energy in sensitive tissues. Although animal studies have been useful in assessing space radiation risks, anatomical and physiological differences limit their applicability to human anatomy especially neuroanatomy. To address this gap, we developed a computational framework to model radiation dose distribution within the human brain using Monte Carlo simulations in Particle and Heavy Ion Transport code …

Spase: Spatially Resolved Pathology Scores Using Optimal Transport On Spatial Transcriptomics Data, Mohammad Nuwaisir Rahman, Mohammed Abid Abrar, Vikram Rakesh Shaw, James F Martin, M Saifur Rahman, Md Abul Hassan Samee

Faculty, Staff and Students Publications

Pathological events often impact tissue regions in a spatial variable manner, making it challenging to identify therapeutic targets. Spatial transcriptomics (ST) is a powerful technology to map spatially variable molecular mechanisms, yet suitable analytical methods have been lacking. We introduce SPaSE (Spatially-resolved Pathology ScorE), an optimal transport-based algorithm to compare ST data from diseased and control tissues. SPaSE computes a “pathology score” for each spot in the diseased sample, quantifying the pathological impact at that spot. In post-MI (myocardial infarction) mouse hearts, these scores delineated zones that matched independent expert annotations. Modeling pathology scores from gene expression revealed signatures predictive …

Anxiety's Impact On Autism Spectrum Disorder Symtomology: An Investigation Into The Relationship Between Two Comorbities, Michaela Brown

LSU Doctoral Dissertations

Autism spectrum disorder (ASD) has been found to be frequently comorbid with many medical and psychological disorders, one of which is anxiety disorders. Research has shown that, when anxiety is present within ASD, various areas of the child’s functioning may be impacted, such as ASD symptom severity, emotional regulation skills, adaptability, social skills and daily living skills. The current study aimed to investigate this relationship of anxiety and ASD. First, within a sample of children and adolescents with ASD, the magnitude of the correlation between specific ASD symptoms parent-reported anxiety was compared to determine if certain ASD symptoms were more …

For Us, By Us: A Digital Ethnographic Exploration Of Black Podcasts, Intimacy, & Sexual Pleasure, Dominique C. Dillard

LSU Doctoral Dissertations

Sociological literature written about Black folks interprets their sexual behavior as unhealthy, risky, and non-normative. Black people are seldom acknowledged as humans, so it is not surprising to discover a discourse that does not portray them as sexual subjects. Studies examining Black sexual subjectivity through white and colorblind ideologies dominate the discussion, reproducing racist discourse historically ascribed to Black bodies. Guided by Audre Lorde’s concept of erotic as power, I document an alternative epistemology about Black sexuality. I argue the construction of Black sexuality must focus on sexual selfhood to grasp how this population conceptualizes and makes sense of their …

A Comparative Case Study Of Mentoring Practices By National Board Certified And Non-Certified Teacher Mentors, Bethany Mcclure

LSU Doctoral Dissertations

As preservice teacher candidates engage in field experiences that shape their development of teacher identity, it is important to examine their perceptions of the mentoring process. This study explored how preservice teacher candidates construct their own knowledge about mentoring as a process, as well as explored the perceptions of mentor teachers, both National Board Certified, and non-National Board Certified, as they facilitated the learning and growth of their mentees. Many prior studies on the mentoring process exist, however, a gap in the literature that was identified and explored through this study included the impact that National Board Certified Teachers have …

Digital Forensics (DF) is a field of forensic science focusing on the acquisition, authentication, and analysis of digital evidence while maintaining integrity of that data. DF analysts use forensic tools to parse large volumes of data for investigations and depend on them for identification of pertinent digital evidence in vast amounts of data. Keeping up with innovations and ever-expanding data volumes is a constant challenge for these investigators. The prevalence of Artificial Intelligence (AI) in everyday computing is rapidly expanding, with the use of Machine Learning (ML) and Large Language Models (LLM)s becoming increasingly commonplace. Innovations in technology bring new …

Towards Leveraging Social Media Data For Fostering Collaborations Among Non-Profits, Monazil Chowdhury

LSU Doctoral Dissertations

Nonprofit organizations serve a crucial role in tackling a wide range of significant social, environmental, and economic issues. But it is often hard to get a clear picture of their work because their information is spread out and it is difficult to see how they are collaborating. To address this issue we developed a web-based tool to collect scattered data—from a variety of sources, such as the IRS, social media, and the Census, into one easy-to-use resource. The tool begins by taking IRS records and geocoding each nonprofit’s physical address With its coordinates. It then retrieves census tract information from …

Cryo-Em Structures Of A Pentameric Ligand-Gated Ion Channel In Liposomes, Vikram Dalal, Brandon K Tan, Hanrui Xu, Wayland W L Cheng

2020-Current year OA Pubs

Detergents and lipid nanodiscs affect the cryo-EM structures of pentameric ligand-gated ion channels (pLGICs) including ELIC. To determine the structure of a pLGIC in a membrane environment that supports ion channel function, we performed single particle cryo-EM of ELIC in liposomes. ELIC activation and desensitization were confirmed in liposomes with a stopped-flow thallium flux assay. Using WT ELIC and a non-desensitizing mutant (ELIC5), we captured resting, activated, and desensitized structures at high resolution. In the desensitized structure, the ion conduction pore has a constriction at the 9' leucine of the pore-lining M2 helix, indicating that 9' is the desensitization gate …

Identification Of Functional Non-Coding Variants Associated With Orofacial Cleft, Priyanka Kumari, Ryan Z Friedman, Michael A White, Barak A Cohen, Et Al.

2020-Current year OA Pubs

Oral facial cleft (OFC) comprises cleft lip with or without cleft palate (CL/P) or cleft palate only. Genome wide association studies (GWAS) of isolated OFC have identified common single nucleotide polymorphisms (SNPs) in many genomic loci where the presumed effector gene (for example, IRF6 in the 1q32 locus) is expressed in embryonic oral epithelium. To identify candidates for functional SNPs at eight such loci we conduct a massively parallel reporter assay in a fetal oral epithelial cell line, revealing SNPs with allele-specific effects on enhancer activity. We filter these SNPs against chromatin-mark evidence of enhancers and test a subset in …
