Llnl Raft Flash Pole Redesign, Jack Stangel, Evan Wolfson, Jake Borden, Alexander Meeter

Mechanical Engineering

During research exercises in the ocean, Lawrence Livermore deploys a fleet of rafts outfitted with flash modules affixed to tall poles (in tandem called flash poles) that flash while a photo is taken to act as datums for data collection. The current flash pole design that the LIDSS (Lawrence Livermore Independent Diagnostic Scoring System) team uses is too short to be visible in high seas, not mechanically suited to be made taller, too susceptible to the elements and blunt impact and too difficult to service. We aim to solve these issues.

You have built your career at a trauma hospital, so you are familiar with the stress that comes with a daily ratio of six patients to one nurse—and yet, COVID-19 brings constantly evolving challenges that no one anticipated. On a typical day, during the height of the pandemic, your consecutive twelve-hour workdays become a blur as you and …

Belowground Biomass Shifts Along A Temperate Forest Edge, Lara Holbrook Roelofs

Dartmouth College Undergraduate Theses

Anthropogenic land use change and development has caused widespread global forest fragmentation, resulting in a greater proportion of forests at or near a forest edge. Temperate forests are the most fragmented forest biome, and forests in the Northeastern U.S. are particularly fragmented due to a history of intense land use and development pressure. Nearly a quarter of these forests are now within 30 meters of a forest edge. These edge ecosystems have distinct abiotic and biotic gradients that differentiate them from forest interiors, including increased light, temperature, and exposure to wind and other disturbances, as well as decreases in humidity …

Design Principles For Robotic-Controlled 3d Printing Of Soft Tissue-Mimicking Materials, Karina Mealey

Master's Theses

Geometrically and physically accurate 3D models are emerging as essential tools for surgeons in pre-operative planning and training, but current methods of producing these models are not sufficient. Existing solutions have downsides such as high costs, long and tedious production times, high complexity resulting in a lack of scalability, or an inability to meet material requirements for accurately simulating human tissue.

The objective of this work is to develop principles for a low-cost, easy-to-use 3D printing system capable of prototyping with soft tissue-mimicking materials. To pursue this goal, a MyCobot280 robot arm was used as the mechanism to explore the …

The Application Of Lidar For Classifying Wildland Fuels, Madison Muschetto

Master's Theses

Accurate vegetation classification is critical for modeling wildfire behavior, particularly in fire-prone ecosystems where fuel type influences fire spread and intensity. This study evaluates the effectiveness of UAV-based aerial LiDAR, supplemented by multispectral imagery, for classifying grass, shrub, and tree vegetation types across a grass-dominated landscape. Using canopy height thresholds, vertical profile analysis, LiDAR predictions were compared against field-verified vegetation observations at 80 survey points. Results showed that LiDAR classified grass with high accuracy but was less reliable for detecting shrubs and trees, especially under canopy cover. Misclassifications were most common beneath tree canopies and in areas where low-stature shrubs …

Topodino: Self-Supervised Topological Representation Learning For Neuronal Morphologies, Yasser Binbisher

Master's Theses

Neuronal cell types are categorized by transcriptomic identity, yet their morphological heterogeneity defies this classification. In response, researchers have adopted unsupervised graph representation learning as a tool to reveal morphological variation within single-class transcriptomic types. However, the complex geometry of neuronal morphology—especially long axons and dense dendrites—challenges graph neural networks, which struggle with message propagation across extended structures. To mitigate this, current approaches enforce sub-sampling on neuronal graphs and omit axons entirely, sacrificing critical biological features for computational efficiency. To overcome this trade-off, this thesis introduces TopoDINO, a self-supervised, topology-aware representation learning model designed to preserve the full hierarchical organization …

"The Effect Of Methylobacterium Symbioticum On The Growth And Yield Of Dent Corn And Romaine Lettuce", Sinead Carney

Master's Theses

Nitrogen (N) is an essential nutrient for plant growth and is often a limiting nutrient in cropping systems. An estimated half of applied N fertilizers are lost from cropping systems by processes that can be environmentally destructive, such as leaching and volatilization, and cause economic loss for growers. Effective N biofertilizers offer a means to mitigate the need for high inputs of synthetic N. The objectives of this study were to determine the effects of leaf inoculation with the N-fixing bacteria, Methylobacterium symbioticum, in combination with different rates of urea-N fertilizer on the physiology and yield of dent corn …

From Tree To Shrub? The Fate Of Tanoak Through Fire And Nonnative Disease, Jacqueline Rose

Master's Theses

Invasive plant pathogens have killed an uncountable number of trees and disrupted ecosystem processes throughout the world. Newly introduced pathogens may interact with historically occurring disturbances in unexpected ways to cause amplified mortality and change to ecosystem processes. Here, I examine the a natural experiment created by three wildfires in Big Sur, a portion of the central coast of California impacted by the nonnative pathogen Phytophthora ramorum, to forecast the future of a species susceptible to the pathogen. Using a plot network which spans the length of Big Sur, I track the survival of individual tanoak (Notholithocarpus densiflorus) stems and …

Stability Insights From Modeling Chronic Myelogenous Leukemia, Giovani Thai

Master's Theses

This thesis centers around a model for chronic myelogenous leukemia (CML) as it behaves under imatinib treatment, a common medication for CML patients, and the anti-leukemia immune response. The dynamics are represented with a system of nonlinear delay-differential equations first constructed by Kim et al. in 2008, capturing population changes of T-cells and various CML growth stages. We investigate stability in both the clinical and mathematical sense. Through numerical simulations, we computationally incorporate a supplementary treatment plan to determine its effectiveness in aiding immune response and medication in achieving remission and full elimination. The primary goal is to conduct a …

Genetic Analysis Of Psychosis Biotypes: Shared Ancestry-Adjusted Polygenic Risk And Unique Genomic Associations, Cuihua Xia, Ney Alliey Rodriguez, Carol A. Tamminga, Matcheri S. Keshavan, Godfrey Pearlson

School of Medicine Publications

The Bipolar-Schizophrenia Network for Intermediate Phenotypes (B-SNIP) created psychosis Biotypes based on neurobiological measurements in a multi-ancestry sample. These Biotypes cut across DSM diagnoses of schizophrenia, schizoaffective disorder, and bipolar disorder with psychosis. Two recently developed post hoc ancestry adjustment methods of Polygenic Risk Scores (PRSs) generate Ancestry-Adjusted PRSs (AAPRSs), which allow for PRS analysis of multi-ancestry samples. Applied to schizophrenia PRS, we found the Khera AAPRS method to show superior portability and comparable prediction accuracy as compared with the Ge method. The three Biotypes of psychosis disorders had similar AAPRSs across ancestries. In genomic analysis of Biotypes, 12 genes, …

Differential Gene Expression Study In Whole Blood Identifies Candidate Genes For Psychosis In African American Individuals, Emma M. Knowles, Juan M. Peralta, A. L. Rodrigue, Samuel R. Mathias, Josephine Mollon, Ana C. Leandro, Joanne E. Curran, John Blangero, David C. Glahn

School of Medicine Publications

Genome-wide association has identified regions of the genome that mediate risk for psychosis. It is possible that variants in these regions confer risk by altering gene expression. This work has predominantly been conducted in individuals of European descent and has focused narrowly on schizophrenia rather than psychosis as a syndrome. In the present study we investigated alterations in gene expression in African American individuals with a range of psychotic diagnoses to increase understanding of the etiology in an underserved population. We performed RNA-seq in whole bloody to survey the transcriptome in 126 patients with a psychosis-spectrum disorder and 217 healthy …

Nursing Advocacy In Maternal Health For Women With Sickle Cell Disease, Jodian Lyn

Loma Linda University Electronic Theses, Dissertations & Projects

Over 80% of pregnancy-related deaths among Black women in the U.S. are preventable. Racial disparities, biases, and discrimination negatively impact maternal health, by contributing to higher stress levels, affecting pregnancy outcomes. The maternal death rate for Black women with sickle cell (SCD) is 629, Black women without SCD is 12, and the general population 6 per 100,000. The voices of these women are often missing in research.

This qualitative study, using Hermeneutic Phenomenological approach, explores the lived experiences of Black women with SCD during pregnancy. Data analysis was completed using an interpretive framework to elucidate the essence of the lived …

Religiosity And Mental Distress In U.S. Healthcare Workers During Covid-19, Jasmine Logan

Loma Linda University Electronic Theses, Dissertations & Projects

A major impact of the COVID-19 pandemic is the global increased rates of mental distress and decreased levels of resilience in healthcare workers. The development of quick, effective interventions for healthcare workers are all the more needed to maintain job performance and increase well-being. Associations between religion and health have been clearly established, and evidence suggests religious coping as an effective strategy for mental wellbeing. The current study investigated whether religious coping could predict levels of mental distress and resilience in a U.S. cohort of healthcare workers. The sample consisted of 137 healthcare workers from a large healthcare institution who …

The Role Of Swarm Intelligence Systems In Shaping Urban Development Policies, Sudaff Mohammed, Wahda Shuker Al-Hinkawi, Nada Abdulmueen Hasan

Iraqi Journal of Architecture and Planning

Swarm intelligence is a nature-inspired complex system that draws from the behaviours of social creatures such as ants and birds. This system functions through simple behavioural rules enacted by autonomous, intelligent agents. Existing literature indicates that swarm intelligence possesses a wide range of principles and characteristics derived from the theories of Biomimicry, complex adaptive systems, and parametric and generative design. While the previous studies have intensively addressed the computational aspects of intelligence, a comprehensive conceptual framework is essential for analysing complex urban forms and structures. Therefore, this research develops and applies a conceptual model of swarm intelligence by examining several …

Exonerees Working For Work's Benefits: Prison Work For Social Security And Medicare, Stephanie Hunter Mcmahon

Hofstra Law Review

Exonerated individuals are released from prison, but they cannot recover the time they were incarcerated. The time is gone, as is its potential to qualify for the nation’s social safety net. Most people earn a right to the safety net and for retirement through their employment; however, even when prisoners work, they are denied employment-related benefits that would be enjoyed by those not incarcerated. Inmate labor does not earn toward Social Security, Medicare, and Social Security Disability Insurance, and the exclusion applies even if the inmate is later exonerated of the crime for which they were imprisoned. Therefore, exonerees’ mandatory …

Perioperative Fluid Therapy Impairs Lymphatic Pump Function In Male Rats, Rebecca C Harlow-Adamek, Reetu Singh, Randolph H Stewart, Cristine L Heaps, Glen A Laine, Charles S Cox, Ranjeet M Dongaonkar

The Brown Foundation: Institute of Molecular Medicine

Because of its life-saving benefits, perioperative IV fluid therapy remains a cornerstone of medical treatment. However, it also induces sustained edemagenic stress. The resulting persistent interstitial edema-excessive fluid accumulation in the interstitium-significantly delays recovery and worsens patient outcomes. Therefore, to gain a detailed understanding of the lymphatic functional consequences of perioperative fluid therapy, this study aimed to test the hypothesis that perioperative IV fluid therapy compromises lymphatic pump function within 3 days after major surgery. Following a midline laparotomy, animals received IV fluid therapy over 48 h during recovery (FLTP). Three days post-surgery, mesenteric lymphatic vessels from FLTP and sham …

Structural Color Pigments For Waterborne Coatings, Kyle William Liston

Master's Theses

Structural colors offer unique alternatives to conventional pigments, utilizing their microstructures to produce vibrant colors. These pigments offer an alternative source for colorants without the need for less environmentally friendly conventional pigments. In keeping with the sustainability approach, the use of waterborne coatings was chosen over solvent-based coatings. Here we report the synthesis of brushite platelet, silica supraball, and inverse opal pigments. Brushite platelets were produced through a condensation reaction, while silica supraballs were synthesized via the Stöber process and assembly was attempted using an oil-in-water emulsion. Inverse opal was produced through the templating of silica on poly(methyl methacrylate) (PMMA) …

Functionalization Of A Calcium-Based Squaric Acid Metal Organic Frameworks With Amine-Based Polymers For Enhancing Post Combustion Carbon Capture, Corinne D. Watson

Master's Theses

The primary driver of climate change is the release of carbon dioxide (CO₂) from fossil fuel combustion. Global climate change has resulted in sea level rise, adverse weather patterns, and countless other negative global effects. Several carbon-reduction frameworks emphasize the transition to clean energy sources; however, other strategies must be concurrently pursued to immediately and effectively reduce atmospheric carbon dioxide point source emissions. Metal organic frameworks (MOFs) are a promising new technology for post-combustion carbon dioxide capture. The materials are synthesized using organic linker molecules and metal ion joints. Notably, there are several challenges with various types of …
