Using The Flexon Approach To Rnai To Identify Essential Genes That Affect Gonadal Development In C. Elegans, Joyce S. Lefevers

Undergraduate Theses

To elucidate the molecular role of essential genes in the gonadal development of Caenorhabditis elegans (C. elegans) it is necessary to utilize specialized molecular techniques such that the phenotypic effects of gene knockdown can be studied while the viability of the organism is preserved. Shaffer and Greenwald (2022) developed the floxed exon (flexon), a tool that improves upon previous approaches to spatiotemporal control of gene expression. The flexon subunit is made up of an artificial exon with a stop cassette flanked by artificial introns which, when inserted into a gene of interest, prevents the expression of that gene. …

Ar Bubble Car: A Cross-Vehicle Visual Social System For Autonomous Mobility, Bingchang Zhang

Theses

AR Bubble Car argues that in L4/L5 autonomous mobility, or high to fully automated driving, the car should be understood not only as a transportation device but also as a visible social interface in public space. As driving becomes less central, the role of the vehicle shifts from control and movement alone toward passenger experience, expression, and communication. In response, AR Bubble Car proposes a transparent visual bubble around compatible vehicles, allowing passengers to share lightweight content through window-based AR. Rather than treating the car as a private entertainment container, the system explores how vehicles might become moving social nodes …

Wavetable Modification In Frequency Domain: Fourier Analysis With Matlab Implementation, Caleb Kortens

Senior Honors Theses

One of the challenges in creating computer generated music is producing life-like sounds. Music produced through computer synthesis can often sound thin and synthetic rather than vibrant and energetic. Wavetable synthesis is a method of waveform generation that uses a wavetable, which is a set of single period waves, or frames, that have varying characteristics. This method allows a synthesizer to transition between waveforms to produce a sound with time varying tone and harmonic characteristics. This adds life and movement to computer generated sounds. Wavetable synthesis is often used to imitate actual instruments, but unique wavetables can be created that …

The Many Philosophies Of Happiness: A Close Reading Into The Ancient And Contemporary Theories Of Happiness, Georgia M. Thompson

Undergraduate Theses and Capstone Projects

Happiness is a concept that many people claim to identify, but is perhaps only known in theory by few. Often, happiness is described as an emotion, dependent on many factors in a person's life rather than a continuous state of their being. The majority of people who are asked, “What is happiness?”, respond with examples that are subjective, meaning they are based on feeling in a given moment. Examples of this include, financial stability, a spike in emotion at a pleasant birthday party, or the feeling of being well liked by one's peers. Ancient philosophers, such as Plato and Aristotle, …

Yap Induces A Prorenewal Metabolic State In Cardiomyocytes, Lin Liu, Jeffrey D Steimle, Chang-Ru Tsai, Fansen Meng, Yuka Morikawa, Yi Zhao, Sandra Carmichael, Xiao Li, James F Martin

Faculty, Staff and Students Publications

BACKGROUND: Cardiomyocytes, as highly specialized and differentiated somatic cells, possess a limited capacity for renewal. Neonatal rodents possess the ability to regenerate cardiomyocytes after injury; however, this regenerative capacity declines rapidly with cardiomyocyte maturation, suggesting an inhibitory network between cellular maturation and cardiomyocyte proliferation. Maturing cardiomyocytes undergo a metabolic shift from predominantly glycolysis in the neonatal state to increased fatty acid oxidation in the mature state, which poses a barrier to cardiomyocyte proliferation and cardiac regenerative repair. YAP, a transcriptional cofactor regulated by the Hippo signaling pathway, promotes cardiac regenerative repair. We investigated the role of YAP in mediating metabolic …
