High Strain Rate Behavior Of Soft Polymeric Materials : Polymer-Bonded Explosive Simulants And Polyimide Aerogels, Benjamin Jeffrey Solomon

Theses

Soft polymeric materials exhibit strain sensitive behaviors and are used in various applications where dynamic loading conditions may be present, making understanding the responses at high rates vital to safe application. Investigation of the mechanical response of soft materials at high strain rates has proven challenging due to low forces, mismatching impedances, and longer times to obtain dynamic force equilibrium limiting the quality and accuracy of data acquisition. Two polymeric materials were evaluated in this study. The first is polymer-bonded explosive (PBX) 9501, which experiences dynamic loading during use as solid propellant and warhead explosive material. It is found that …


Discovering The Genes And Molecular Mechanisms Involved In Increasing The Expression Of The Gad Regulon In Escherichia Coli Resistant To Macrolide Antibiotics, Lea V. Freeman Jan 2026

Discovering The Genes And Molecular Mechanisms Involved In Increasing The Expression Of The Gad Regulon In Escherichia Coli Resistant To Macrolide Antibiotics, Lea V. Freeman

Theses

Various genes have been proposed to play a role in the action of indole, a bacterial hormone involved in biofilm and quorum sensing. Previous work found that E. coli strains carrying a macrolide-resistant mutation in the uL22 ribosomal protein reduce tna operon mRNA levels and, consequently, decrease indole production. This ribosomal mutation also increases expression of the gad regulon, a genetic unit involved in acid resistance at pH below 2. The gad regulon is involved in bacterial survival under environmental challenges, primarily regulating intracellular acid resistance, and its expression appears to depend on indole production. In this work, we work …

Dietary Intake Of Micro- And Nanoplastics: Potential Adverse Gi Effects On Microbiome, Inflammation, And Neoplasia, Michael Saadeh, Gordon Hong, Sana Rabeeah, Priyata Dutta, Edward C. Oldfield, Iv, David A. Johnson Jan 2026

Dietary Intake Of Micro- And Nanoplastics: Potential Adverse Gi Effects On Microbiome, Inflammation, And Neoplasia, Michael Saadeh, Gordon Hong, Sana Rabeeah, Priyata Dutta, Edward C. Oldfield, Iv, David A. Johnson

Department of Medicine Faculty Publications

Micro- and nanoplastics (MNPs) are pervasive in food-contact environments and the human diet, positioning the gastrointestinal (GI) tract as the primary portal of entry and a plausible site of early biological effects. Human exposure is supported by detection of microplastics in stool and colon tissue, and emerging clinical studies report associations between fecal microplastic burden and GI disease states, including inflammatory bowel disease (IBD) and colorectal cancer (CRC). Preclinical studies provide mechanistic plausibility, reporting that ingested MNPs can modulate microbial ecology, alter mucus membrane integrity, increase intestinal permeability through changes in cellular tight junction biology, and induce inflammatory gene expression. …

A Framework For Evaluating Riparian Climate Refugia In The Eel River Watershed, California, Farrah Tyler Jan 2026

A Framework For Evaluating Riparian Climate Refugia In The Eel River Watershed, California, Farrah Tyler

Cal Poly Humboldt theses and projects

Climate change is increasing the need to identify and protect landscapes that support biodiversity through both habitat connectivity and climate refugia. Climate refugia are areas that remain relatively buffered from regional climatic change, enabling species to persist despite shifting environmental conditions. Riparian ecosystems can function as both movement corridors and climate refugia, yet methods for identifying these features and understanding the environmental processes that sustain them remain limited. In California's North Coast region, the identification and conservation of watersheds that may serve as climate refugia for sensitive plant and animal species will be essential for long-term ecosystem management and conservation. …

Multimodal Late-Fusion Of Radiomics, Clinical Data, And Demographics Enhances Personalized Survival Prediction In Nsclc, Zarindokht Helforoush, Mohamed Jaber, Nezamoddin N. Kachouie

Mathematics and System Engineering Faculty Publications

Backgrounds/Objectives: Non-small cell lung cancer (NSCLC) exhibits substantial prognostic heterogeneity that is not fully captured by conventional anatomical staging, highlighting the need for individualized risk assessment. Radiomics enables non-invasive characterization of tumor phenotype, yet high dimensionality and inter-feature correlations often limit model stability and interpretability. Methods: To address these challenges, we developed a multimodal late-fusion framework integrating radiomic, clinical, and demographic information to predict patient-specific absolute risk in the Lung1 cohort (N = 398). Radomic features (N = 107) were extracted from primary tumor volumes and refined using a Group Lasso–penalized Cox model, preserving biological coherence and producing a parsimonious …


Aquatic Habitat Use By Western Toads And American Bullfrogs In California’S Central Valley: Effects Of Local Habitat Characteristics And Landscape Composition, Kaitlyn Breana Hernandez Jan 2026

Aquatic Habitat Use By Western Toads And American Bullfrogs In California’S Central Valley: Effects Of Local Habitat Characteristics And Landscape Composition, Kaitlyn Breana Hernandez

Cal Poly Humboldt theses and projects

Drastic losses of historic wetland habitat in the California Central Valley have caused widespread population declines and extirpations of aquatic breeding amphibians. Efforts to restore wetland habitat have included private land, which represents 70% of land tenure in the Central Valley. Management of these restored wetlands is focused on waterfowl with the assumption that they will provide habitat for native herpetofauna. This study used combined surveys to test the assumption that restored wetlands on private land provide habitat for native amphibians with the western toad (Anaxyrus boreas) as a case study. The objectives were to use environmental DNA …

Coho Salmon (Oncorhynchus Kisutch) Response To Habitat Restoration Through Space And Time: Monitoring Growth, Survival, And Movement In A Restored Habitat Network, Carter Perez Adamson

Cal Poly Humboldt theses and projects

Despite the decline of coho salmon (Oncorhynchus kisutch), Prairie Creek, a tributary of Redwood Creek in northern California, remains a coho salmon stronghold. The restoration of juvenile coho rearing habitat was identified as a recovery objective in this watershed by the National Marine Fisheries Service. Among the restoration projects addressing this objective are an ongoing project on Prairie Creek and its tributary Skunk Cabbage Creek, and a prior effort on Strawberry Creek (a tributary of Redwood Creek’s estuary). Standard monitoring methods for assessing project success have limitations and may be improved by measuring salmon use of restored habitats …


Examining The Physiological Stress-Reducing Effects Of Virtual Nature Exposure And Slow Breathing, Jesse Benefiel Jan 2026

Examining The Physiological Stress-Reducing Effects Of Virtual Nature Exposure And Slow Breathing, Jesse Benefiel

Cal Poly Humboldt theses and projects

In a time of excess stress, it is essential to examine accessible stress-reduction methods. Research has demonstrated that virtual nature exposure and slow breathing can independently reduce stress, but the literature is lacking with regard to their combined effects. The present study aimed to replicate independent effects of breathing and nature on stress and to test for potential effects, including whether their combination would produce an interaction effect. Using a 2 Environment (Natural v. Control) by 2 Breathing (Slow v. Normal) between-subjects design, 63 participants completed a modified color-word Stroop task to induce stress and were then exposed to either …


Species Boundaries Of The Rare Menzies’ Wallflower (Brassicaceae: Erysimum Menziesii), An Endemic Of The Northern California Coast, Cameron M. Jones Jan 2026

Species Boundaries Of The Rare Menzies’ Wallflower (Brassicaceae: Erysimum Menziesii), An Endemic Of The Northern California Coast, Cameron M. Jones

Cal Poly Humboldt theses and projects

Morphological similarity among geographically isolated populations can obscure deep evolutionary divergence, especially when convergent evolution under similar environmental conditions yields comparable phenotypes across independent lineages. Such cryptic diversity is likely underestimated in hotspots like the California Floristic Province (CFP), a global biodiversity hotspot, defined by its Mediterranean-like climate and encompassing most of California, southwestern Oregon, and northwest Baja California. The CFP is home to a disproportionate number of narrow endemics whose origins and evolutionary relationships remain poorly understood. Here, I investigate the evolutionary origins of Erysimum menziesii (Brassicaceae), a federally endangered California coastal dune endemic whose fragmented distribution has led …


Succession And Alpine Plant Habitat Of A Recently Deglaciated Foreland In The Trinity Alps, California, Sebastian Evans Jan 2026

Succession And Alpine Plant Habitat Of A Recently Deglaciated Foreland In The Trinity Alps, California, Sebastian Evans

Cal Poly Humboldt theses and projects

The recent extinction of the Salmon Glacier in the Trinity Alps, California, provides a rare opportunity to examine post-glacial succession in a region of high endemism experiencing climatic stress. Using a chronosequence spanning ~150 years since deglaciation, I investigated (1) vegetation successional trajectories in the foreland, (2) whether the foreland functions as a climate refugium for alpine specialists, and (3) whether facilitative interactions between the dominant vascular plant (DVP) and bryophytes occur and persist through succession. I surveyed 100 plots across 11 transects within the foreland and 40 randomized plots in adjacent ecosystems. Successional patterns and refugial potential were analyzed …


Development Of The Core Lit Apparatus For Seaweed Hatcheries (Clash) Bioreactor Using A Germplasm Approach, Phillip O. Tahimic Jan 2026

Development Of The Core Lit Apparatus For Seaweed Hatcheries (Clash) Bioreactor Using A Germplasm Approach, Phillip O. Tahimic

Cal Poly Humboldt theses and projects

In comparison to the Asian aquaculture industry, the United States has minimal seaweed production. There are several drivers of the limited industry in the US, such as regulatory constraints and limited market demand, but the ability to scale is a considerable barrier to commercialization. One possible solution is the development of land-based systems that integrate bioreactors, which utilize fewer resources and do not wholly rely on an oceanic flow-through system. This study assessed the application of a modular bioreactor, known as Core Lit Apparatus for Seaweed Hatcheries (CLASH), as a nursery system and open-source project designed to expand land-based seaweed …


Land Cover Classification Using Optimized Imagery Resolution And Machine Learning Algorithms For A Long-Term Monitoring And Restoration Project, Jessica R. Suoja Jan 2026

Land Cover Classification Using Optimized Imagery Resolution And Machine Learning Algorithms For A Long-Term Monitoring And Restoration Project, Jessica R. Suoja

Cal Poly Humboldt theses and projects

Ecosystem services and functions are prone to water resource exploitation resulting in cascading effects that include decrease of biodiversity and loss of riparian vegetation, a keystone habitat in desert riparian ecosystems. Mono Lake is a prime example of overexploitation of water resources leading to legal action and eventually a legally mandated long-term monitoring and restoration project. Monitoring and restoration projects can benefit from techniques such as remote sensing and machine learning algorithms to generate accurate land cover classification maps for calculating land cover change over time. However, the spatial resolution of remote sensing imagery and the machine learning algorithms chosen …


Supporting Risky Outdoor Play Through Professional Development: A Quasi-Experimental Study Of Tk–6 Educators’ Attitudes, Justin Ross Burrill Jan 2026

Supporting Risky Outdoor Play Through Professional Development: A Quasi-Experimental Study Of Tk–6 Educators’ Attitudes, Justin Ross Burrill

Cal Poly Humboldt theses and projects

Children’s opportunities for active outdoor risky play have declined in many educational settings, despite evidence that manageable risk supports physical activity, self-regulation, confidence, resilience, and social participation. Educator attitudes and school culture may play an important role in determining whether children are offered developmentally appropriate opportunities for challenge, exploration, and autonomy. This quasi-experimental, single-group pretest-posttest study examined whether participation in a single-session professional development workshop was associated with changes in educators’ tolerance of risk in children’s play. Thirty educators attended a workshop focused on risky play, hazard-risk differentiation, inclusion of children with disabilities, loose-parts play, environmental affordances, and practitioner-informed implementation …


Contribution Of Lagoon-Rearing Juvenile Chinook Salmon (Oncorhynchus Tshawytscha) To The Adult Spawning Population In The Mattole River, Emma Held Jan 2026

Contribution Of Lagoon-Rearing Juvenile Chinook Salmon (Oncorhynchus Tshawytscha) To The Adult Spawning Population In The Mattole River, Emma Held

Cal Poly Humboldt theses and projects

Bar-built estuaries are rivermouth confluences characterized by periods of disconnection between the river and the ocean due to a sandbar that builds across the mouth. Sandbar timing characteristics vary between years and between systems, but when closed, a lake-like lagoon forms in the estuary footprint. The Mattole River has a bar-built estuary that forms in late spring or early summer, often overlapping with juvenile Chinook salmon outmigration. Juveniles that do not leave the river before the bar closes must remain in the lagoon until the mouth opens in fall. The purpose of this thesis was to understand if lagoon-rearing is …


Factors Influencing Tree Vigor And Structural Failure Along Powerline Corridors In Northern California: A Multi-Species Analysis, David Justin Dorval Jan 2026

Factors Influencing Tree Vigor And Structural Failure Along Powerline Corridors In Northern California: A Multi-Species Analysis, David Justin Dorval

Cal Poly Humboldt theses and projects

Tree failures (e.g., stem breakage, uprooting, or branch drop) can pose significant risks to public safety, particularly along powerline corridors for the risk of power outages and wildfire ignitions. In California, tree-related powerline failures have led to severe ecological and human costs in recent years. Despite extensive research on tree failure in urban environments and post-disturbance contexts, comparatively little empirical work has examined where powerlines intersect largely unmanaged stands. This study evaluates tree failure trends across multiple forest types in Northern California by examining how tree-level characteristics influence recent growth and failure occurrence in regionally dominant tree species. Specifically, the …

Dextromethorphan And Trace Level Detections Of Dextrorphan In Post-Race Urine Samples – A Case Report And Analysis, Kimberly Brewer, Justin C. Holmes, Clara Fenger, Abelardo Morales-Briceño, Andreas F. Lehner, George A. Maylin, Robert Holland, Levent Dirikolu, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

Dextrorphan is a Phase I equine metabolite of dextromethorphan, a widely used anti-tussive / cough suppressant medication marketed and available in numerous over-the-counter formulations in the United States. Dextromethorphan is an Association of Racing Commissioners International (ARCI) drug class 4 penalty class B substance and a Horseracing Integrity and Welfare Authority (HIWU) CONTROLLED S7 B substance and is regulated as such in horse racing. In horses, dextromethorphan is metabolized to its Phase I metabolite, dextrorphan, which is next glucuronidated and the resultant dextrorphan-glucuronide conjugate then excreted at remarkably high concentrations in equine urine. Dextrorphan is therefore at times identified in …


Optimizing Control Definitions In Opioid Use Disorder Genetic Research Using Electronic Health Records, Maria Niarchou, Ellen L Tsai, Mariela V Jennings, Annika Faucon, Hyunjoon Lee, Kritika Singh, Justin D Tubbs, Panos Roussos, Tian Ge, Richard C Crist, Rachel Vickers-Smith, Howard Edenberg, Amy Moore, Bradley T Webb, Eric O Johnson, Rachel L Kember, Jordan W Smoller, Lea K Davis, Brandon J Coombes, Georgios Voloudakis, David Burstein, Travis T Mallard, Vanessa Troiani, Sandra Sanchez-Roige Jan 2026

Epidemiology and Environmental Health Faculty Publications

Amidst the opioid crisis, understanding the genetic basis of opioid use disorder (OUD) is crucial for identifying biological mechanisms and intervention points. However, genome-wide association studies (GWASs) have been hampered by inadequate sample sizes and often the use of control populations not assessed for prior opioid exposure. Because opioid exposure is a prerequisite for the development of OUD, consideration of exposure history in controls is important. Electronic health record data (EHR) paired with genomic information allow a broader sampling of patients with OUD and exposed controls. We leveraged data across two healthcare systems to evaluate the impact of using controls …


Metabolic Reprogramming Following Mitochondrial Transfer Between Idh2-Mutant Chondrosarcoma Cells And A Normal B-Cell Line, Caleb Wyckoff, Christopher Osgood, Ellen Jing, Michael Stacey Jan 2026

Metabolic Reprogramming Following Mitochondrial Transfer Between Idh2-Mutant Chondrosarcoma Cells And A Normal B-Cell Line, Caleb Wyckoff, Christopher Osgood, Ellen Jing, Michael Stacey

Bioelectrics Publications

Background/Objectives: Chondrosarcoma, glioblastoma, acute myeloid leukemia, chronic lymphocytic leukemia, and cholangiocarcinoma cancers all contain mutations in the gene isocitrate dehydrogenase 2 (IDH2). The mutant IDH2 enzyme metabolizes alpha-ketoglutarate (αKG) into the potent oncometabolite D-2-hydroxyglutarate (D2HG) in the mitochondria of these cancers, leading to altered cellular metabolism. Emerging evidence suggests that mitochondrial transfer between cancer and recipient cells represents an important form of intercellular communication that may influence cellular metabolism. The presence of intercellular TNTs between IDH2-mutant chondrosarcoma cells motivated an investigation into mitochondria-associated physiological changes occurring during an intercellular exchange with immune cells. A mitochondrial transfer is a two-way …

Establishment And Histopathological Characterization Of A Kyse-30 Subcutaneous Xenograft Model Of Esophageal Squamous Cell Carcinoma, Pavel A. Solopov, Alayna Enos, Mantas Silkunas, Giedre Silkuniene, Eleni Zivla, Andrei G. Pakhomov, Olga N. Pakhomova

Bioelectrics Publications

Background/Objectives: Esophageal squamous cell carcinoma (ESCC) is an aggressive malignancy with poor prognosis and limited treatment options, highlighting the need for reliable preclinical models for translational research. Although xenograft models are widely used in cancer biology, systematic characterization of subcutaneous ESCC models under defined implantation conditions remains limited. The objective of this study was to systematically compare implantation conditions and define histopathological and growth-related parameters that enable reproducible tumor establishment while maintaining a practical experimental window for therapeutic studies. Methods: We established and characterized a subcutaneous ESCC xenograft model using human ESCC cell line KYSE-30 implanted into immunodeficient J:NU mice. …


Targeting Ptp4a3 And Kvx-053 Mitigates Alcohol-Amplified Sars-Cov-2 Spike Protein-Induced Acute Lung Injury, Pavel A. Solopov, Ruben Manuel Luciano Colunga Biancatelli, Elizabeth R. Sharlow, John S. Lazo, John D. Catavas Jan 2026

Targeting Ptp4a3 And Kvx-053 Mitigates Alcohol-Amplified Sars-Cov-2 Spike Protein-Induced Acute Lung Injury, Pavel A. Solopov, Ruben Manuel Luciano Colunga Biancatelli, Elizabeth R. Sharlow, John S. Lazo, John D. Catavas

Bioelectrics Publications

Introduction: Chronic alcohol exposure is associated with increased vulnerability to acute respiratory distress syndrome (ARDS), and emerging evidence suggests that this susceptibility extends to the severe respiratory manifestations of COVID- 19. The SARS-CoV-2 Spike Protein S1 subunit (S1SP) can independently trigger robust inflammatory and vascular injury responses in the lung, and our prior work demonstrated that chronic alcohol consumption markedly intensifies these effects in mice. PTP4A3 phosphatase is a key regulator of inflammation and endothelial barrier function. In this study, we investigated whether the PTP4A3 inhibitor KVX-053 can counteract alcohol-enhanced S1SP-induced lung injury in K18-hACE2 mice.

Methods: Animals were maintained …

Synergistic Sensitization Of Pancreatic Cancer Cells By Nanosecond Pulsed Electric Fields And Cold Atmospheric Plasma Via Amplifying Ros And Apoptotic Signaling, Zobia Minhas, Edwin A. Oshin, Lifang Yang, Chunqi Jiang, Siqi Guo

Bioelectrics Publications

Pancreatic cancer remains a highly lethal malignancy, with standard therapies offering limited benefits in advanced stages; thus, novel strategies that exploit specific cancer cell vulnerabilities are urgently needed. Building on our previous findings that nanosecond pulsed electric fields (nsPEF) combined with cold atmospheric plasma (CAP) produce enhanced cytotoxicity, this study investigates the molecular mechanisms underlying this synergy. Pan02 pancreatic cancer cells were subjected to nsPEF, CAP, or a combination of both. We assessed cell viability, reactive oxygen species (ROS) production, and mitochondrial integrity using metabolic assays, flow cytometry, and fluorescence microscopy. Apoptotic markers were evaluated via Western blotting and caspase …


Nanosecond Electric Pulses As A Novel In Situ Vaccination Strategy For Cancer Treatment: Mechanisms, Challenges And Prospects, Siqi Guo Jan 2026

Nanosecond Electric Pulses As A Novel In Situ Vaccination Strategy For Cancer Treatment: Mechanisms, Challenges And Prospects, Siqi Guo

Bioelectrics Publications

Nanosecond electric pulses (nsEPs) are an emerging pulsed-power technology with unique bioelectric characteristics distinct from conventional long-pulse electroporation. As a tunable physical modality, nsEPs can modulate intracellular structures, membrane dynamics, and signaling pathways. Increasing evidence supports nsEPs as a promising non-thermal tumor ablation approach due to their high spatial precision, preservation of critical tissue structures, and minimal adverse effects. One of the most significant discoveries associated with nsEP tumor ablation is the induction of potent systemic antitumor immunity, particularly in situ vaccination (ISV) effects and, in some cases, abscopal effects against distant untreated tumors. Substantial evidence demonstrates that nsEPs can …


Cxcr6+ Natural Killer Cell Immunotherapy Preserves Cd4+ T Helper Cells In Humanized Mice, Naushad Khan, Kayla Frank, Silke Paust Jan 2026

Cxcr6+ Natural Killer Cell Immunotherapy Preserves Cd4+ T Helper Cells In Humanized Mice, Naushad Khan, Kayla Frank, Silke Paust

Faculty Research 2026

Human immunodeficiency virus (HIV) persists despite antiretroviral therapy because long-lived viral reservoirs are not eliminated, and ongoing or rebound infection contributes to progressive loss of CD4+ T helper cells. Natural killer (NK) cells can acquire adaptive, antigen-experienced functions, including recall responses to HIV envelope protein, suggesting that defined NK-cell subsets may be therapeutically useful against HIV. Because HIV-responsive adaptive NK-cell activity is enriched among CXC chemokine receptor 6-positive (CXCR6+) NK cells, we tested whether CXCR6+ NK cells provide enhanced antiviral activity and CD4+ T-cell protection compared with CXCR6 NK cells. In co-cultures with HIV-infected …
