Design Of Silicon Grating Metasurfaces For Beam Deflecting In Solid-State Light Detecting And Ranging (Lidar), Matthew Baker

Honors Program Theses and Projects

My thesis begins with an overview of LiDAR (Light Detecting and Ranging) and theory for electromagnetic wave propagation. We establish problems that arise from the use of external beam steering components in LiDAR systems. As a possible solution, we introduce the concept of a metasurface with sub-wavelength dimensions. Grating metasurfaces utilize periodicity to change the phase gradient along a surface. Using a row of posts on a substrate, we can confine light towards one side of a structure, deflecting at angles towards a maximum angle determined by the structure’s geometry. These metasurfaces are small enough to be directly incorporated onto …

Intraspecific Sensory Diversity And The Decapod Claw: Patterns Of Sensillation Are Heterochelic And Sexually Dimorphic In Pagurus Bernhardus, Ari Drummond, Summer Nash, Tianna Holloway, Alexander Wilson, Lucy Turner, Mark Briffa, David T Bilton

School of Biological and Marine Sciences

Information detection affects physiological performance and behaviour and is vital to survival and fitness. Despite the recognised importance of sensory adaptations in information acquisition and manipulation, many forms of sensory variation—from within individuals to between species—remain underexplored. To better understand the role of information in evolution, it is important to examine sensory variation as part of a cohesive framework of sensory diversity. Using the decapod claw, a structure well-recognised for its morphological variation, we investigated sensory diversity at the intraspecific level by assessing heterochely and sexual dimorphism in the chelar morphologies of Pagurus bernhardus hermit crabs. We employed a novel …

Minimal Anti-Cancer Effects Of Mushroom-Derived Compounds Hispidin And Chaga Extract On Ewing Sarcoma Cells, Jordan Cosgrove, Fiona Coulbourne, Iris Reyna, Giselle Serna-Flores, Terry Jo Shackleford

Cell and Molecular Methods

Ewing sarcoma is a rare and aggressive cancer of adolescents and young adults driven by the EWSR1–FLI1 gene fusion. Standard treatments include chemotherapy, surgery, and radiation, though survival rates remain low. Natural compounds such as hispidin, derived from fungi, and Chaga mushroom extract have shown potential anti-cancer effects by disrupting cell cycle progression and promoting apoptosis in other cancer models. In this study, we tested the effects of hispidin and Chaga extract on Ewing sarcoma cells to evaluate their ability to suppress cell growth and identify potential therapeutic benefits.

The Effects Of Hispidin And Eribulin Mesylate On Cell Proliferation Of Ewing Sarcoma Cell Lines, Elena Mares, Angelina Juarrita, Sierra Munoz, Terry Jo Shackleford

Cell and Molecular Methods

Ewing sarcoma is a type of cancer that targets the cells within bones and soft tissue and is most prevalent in younger populations. It is important to look at this specific cancer because there is no cure yet, and the risks increase, even after a patient has completed their treatment. We hypothesize that if we treat Ewing sarcoma cell lines with natural compounds, specifically Hispidin and Eribulin Mesylate, then the cell lines will decrease in cell viability and there will be an increase in apoptosis of the cancerous cell lines. We performed a series of experiments, which included IC50 analysis, …

On The Use Of Nonlinear Electrophoresis For Separating Particles And Cells In Insulator-Based Electrokinetic Systems, Alaleh Vaghef-Koodehi

Theses

The increasing demand for efficient separation processes of micron-sized particles, including microorganisms, highlights the importance of developing low-cost, non-labor-intensive, and time-efficient techniques. Insulator-based electrokinetic (iEK) systems have proven to be a practical alternative to bench-scale methodologies such as centrifugation and membrane filtration. Several studies have reported the separation of microparticles by employing direct current (DC) voltages. However, all of them have overlooked the phenomenon of nonlinear electrophoresis (EPNL) and its role in the electrokinetic migration of particles. This study combines mathematical modeling and experiments to extend the capabilities of iEK systems. This dissertation has four aims: (1) to separate microparticles …

Federal And State Governments Can Help Solve The Employment Problems Of People In Distressed Places To Spur Equitable Growth, Timothy J. Bartik

Upjohn Institute Policy Papers

Places in the United States differ greatly in their residents’ access to jobs, especially good jobs. Although the federal and state governments provide about $80 billion annually to create jobs through multiple programs, these job-creation initiatives are rarely targeted to economically distressed places, where the job-creation benefits for local residents are greatest. Moreover, many of these programs take the form of business tax incentives, which are less effective at job creation than customized services for businesses and workers. I argue that the prime-age employment rate of places should be used to target job-creation programs and review which such programs are …

Identity And The Russian-Ukrainian War: Evidence From The American Community Survey, Matthew Holian, Oleh Wolowyna

Faculty Research, Scholarly, and Creative Activity

The Russian invasion of Ukraine in 2022 led to significant changes in ethnic identity and language preferences among U.S. residents. We observe an 18.9% increase in U.S.-born individuals identifying as ethnic Ukrainian from 2021 to 2022 and a 6.8% decrease for U.S.-born ethnic Russians, which cannot be attributed to prior trends or sampling variation. The changes among Ukrainians were more pronounced among college graduates and those living in Democratic-leaning counties. We document an increase in the use of the Ukrainian language among Ukrainian immigrants, which cannot be explained by prior trends or immigration patterns. We test for labor market discrimination, …

Entomology and Plant Pathology Faculty Publications and Presentations

Biochar is a charcoal-like substance made by the pyrolysis of organic material from agricultural and forestry waste. While biochar is well documented for altering soil physicochemical conditions, few studies have investigated its possible effects on the management of arthropod pests. Tobacco hornworm (Manduca sexta) and fall armyworm (Spodoptera frugiperda, FAW) are specialist and generalist insect herbivores respectively, that can cause significant defoliation in natural and agricultural ecosystems. In this study, we examined whether walnut shell biochar can affect growth and development of these herbivores. Specifically, we investigated how biochar influences parameters such as mass gain, length of pupation, pupal mass, …
