Analysis Of Radial Inlet Distortion On Transonic Fan Performance, Tyler M. Reedy

Theses and Dissertations

Improving fan design and performance prediction requires an understanding of the impacts of inlet distortions. Inlet distortion describes any non-uniform distribution in the flow, usually referring to deviations in pressure and temperature. Using full annulus Unsteady Reynolds-Averaged Navier Stokes (URANS) simulations, the effects of both hub and tip radial distortions on the Air Force Research Lab (AFRL) Rotor 4 fan are analyzed. Overall performance, total pressure (Pt) distortion transfer, and total temperature (Tt) distortion generation are presented and compared for three operating points: near-stall, design, and choke. Hub radial inlet distortion magnitudes of 15% and 20%, and a tip radial …

Faculty, Staff and Students Publications

A tumor cell subpopulation of tumor-initiating cells (TIC) or "cancer stem cells" is associated with therapeutic resistance, as well as both local and distant recurrences. Signal transducer and activator of transcription (STAT) activity is elevated in TICs in claudin-low models of human triple-negative breast cancer, which enables enrichment of TICs using a STAT-responsive reporter. Lineage tracing of TICs as they undergo cell state changes could enable a better understanding of the molecular phenotypes of TIC and uncover strategies to selectively target TICs. In this study, we developed a STAT-responsive lineage-tracing system and used it in conjunction with the original reporter …

Alcohol use is associated with cognitive impairment and dysregulated inflammation. Oral nitrate may benefit cognitive impairment in aging through altering the oral microbiota. Similarly, the beneficial effects of nitrate on alcohol-induced cognitive decline and the roles of the oral microbiota merit investigation. Here we found that nitrate supplementation effectively mitigated cognitive impairment induced by chronic alcohol exposure in mice, reducing both systemic and neuroinflammation. Furthermore, nitrate restored the dysbiosis of the oral microbiota caused by alcohol consumption. Notably, removing the oral microbiota led to a subsequent loss of the beneficial effects of nitrate. Oral microbiota from donor alcohol use disordered …

Using Human Computation And Harmonic Expansions For Characterization And Design Of Grain Boundary Networks, Christopher W. Adair

Theses and Dissertations

Grain Boundary Networks (GBNs) are a high-dimensional feature in polycrystalline microstructural materials that are formed from the crystallographic degrees of freedom. This feature affects multiple material properties such as diffusivity, fracture, elasticity, heat transfer, and others. The link between the crystallography and the material properties is called the structure-property linkage, and allows for simulation and design of materials. While it is possible to use the structure-property linkage to design materials for better performance, the high-dimensional nature of the interconnected grain boundaries preclude the use of many common optimization algorithms for efficiency or local minima considerations. This work shows how the …

Optimizing Epoxy Nanocomposites With Oxidized Graphene Quantum Dots For Superior Mechanical Performance: A Molecular Dynamics Approach, Prathamesh P. Deshpande, Robert Chan-Jobe, Josh Kemppainen, Gregory Odegard, Ozgur Keles

Michigan Tech Publications

Due to their excellent mechanical properties, epoxy composites are widely used in low-density applications. However, the brittle epoxy matrix often serves as the principal failure point. Matrix enhancements can be achieved by optimizing polymer combinations to maximize intermolecular interactions or by introducing fillers. While nanofillers such as clay, rubber, carbon nanotubes, and nanoplatelets enhance mechanical properties, they can lead to issues like agglomeration, voids, and poor load transfer. Quantum dots, being the smallest nanofillers, offer higher dispersion and the potential to promote intermolecular interactions, enhancing stiffness, strength, and toughness simultaneously. This study employed molecular dynamics simulations to design graphene quantum …

Leveraging Agent-Based Modeling And A Randomized Intervention To Advance Childhood Physical Activity: A Study Protocol, Matt Kasman, Adam B. Sedlak, Lydia Reader, William J. Heerman, Russell R. Pate, Amelie G. Ramirez, Evan C. Sommer, Shari L. Barkin, Ross A. Hammond

Faculty Publications

This study (1R01HD107002-01A1) protocol describes the planned creation and use of an agent-based model (ABM) of early childhood physical activity (PA). Successful early childhood PA interventions can potentially play an important role in both increasing overall population health as well as closing health disparities across subpopulations. At present, effective strategies for doing so are currently unknown. In large part, this is because PA determinants operate across levels dynamically, interact with one another, and can differ substantially across children. A complex systems approach—specifically, ABM—can be used to provide important insights about effect pathways driving child PA. Design of the proposed ABM …

Outcomes Evidence Must Keep Up With The Implementation Of The 4ms Framework To Ensure Age-Friendly Health System Transformation, James D Harrison, Stephanie E Rogers, Benjamin Rosner, Estelle Martin, Sunny C Lin, Jarmin Yeh, Julia Adler-Milstein

2020-Current year OA Pubs

The Age-Friendly Health System (AFHS) movement was conceptualized as a transformative solution to reliably deliver evidence-based care to older adults. Guided by the 4Ms framework: What Matters, Mobility, Mentation, and Medication, AFHS healthcare systems have been given the flexibility to tailor 4Ms interventions and care processes to their context, preferences and populations. This flexibility has facilitated the widespread adoption of 4Ms care. However, as our understanding of 4Ms implementation grows, evidence of the impact of 4Ms care on outcomes must keep up with implementation to ensure AFHS transformation. It is only through assessing the 4Ms as a whole and understanding …

Immunotherapeutic Strategies In Head And Neck Cancer: Challenges And Opportunities, Xia Liu, R. Alex Harbison, Mark A. Varvares, Sidharth V. Puram, Guangyong Peng

2020-Current year OA Pubs

HNSCC remains a substantial health issue, with treatment options including surgery, radiation, and platinum-based chemotherapy. Unfortunately, despite progress in research, only modest gains have been made in disease control, with existing treatments resulting in significant functional and quality-of-life issues. The introduction of immunotherapy in the treatment of HNSCC has resulted in some improvements in outlook for patients and is now standard of care for populations with both recurrent and metastatic disease. However, despite the early successes, responses to immune checkpoint inhibition (ICI) remain modest to low, approaching 14%-22% objective response rates. Challenges to the effectiveness of ICI and other immunotherapies …
