Parental Guidance Suggested: Genetic, Epigenetic, And Environmental Factors Shape Allele-Specific Gene Regulation In Metabolic Traits, Celine Louise St. Pierre

Arts & Sciences Graduate Student Theses and Dissertations

Deciphering the “genotype to phenotype” map is a crucial goal of biology. We will not improve our ability to predict phenotypes from DNA sequences until we better incorporate epigenetic and environmental variation into our models of human health and disease. Genes are typically presumed to express both parental alleles equally, but genetic and epigenetic factors can cause one allele to function differently than the other (e.g. expressed or silenced more). These allele-specific imbalances can alter the final composition of a gene’s transcriptional product and ultimately shape phenotypes. Allele-specific effects have widespread impacts on complex traits, but how environmental signals contribute …

High-Quality Factor Phase Gradient Metasurfaces With Dynamic Reconfigurability, Lin Lin

Arts & Sciences Graduate Student Theses and Dissertations

Free-space optical communication holds immense potential for surpassing the bandwidth limitations of conventional physically defined channels. Achieving flexible and efficient communication in free space requires compact, robust optical components capable of dynamically tuning laser light without relying on bulky lenses or mechanically driven mirrors. Metasurfaces, or flat optics, have garnered significant attention due to their densely arranged subwavelength nano-resonators, which impart phase, amplitude, and polarization changes comparable to those of traditional bulky optics. However, conventional phase gradient metasurfaces are constrained by passive designs based on geometric configurations and the weak light-matter interaction inherent in most dielectric materials, limiting their applicability …

Simplicity From Complexity: Sensing High-Dimensional Fluctuations Via Regulatory Network, Optimality In Allocating Cellular Resources, And Recovering Functional Groups Via Data-Driven Methods, Fang Yu

Arts & Sciences Graduate Student Theses and Dissertations

Biological systems must navigate dynamic and complex environments while operating under constraints such as limited molecular resources, biochemical noise, and structural trade-offs. This dissertation investigates three distinct cases in which biological systems allocate resources and process information efficiently, revealing emergent simplicity from underlying complexity. The first study develops a generalized end-product inhibition model with cross-talk and an excess of regulators, providing a proof-of-principle that simple biochemical circuits could, in principle, dynamically adjust their responsiveness to high-dimensional environmental variation. This result highlights how such circuits may allow adaptive filtering of both dominant and subdominant fluctuation modes. The second study, conducted in …

California Red Hummingbird Flowers: Color Convergence Across Four Biochemical Categories, Melissa León-Osper, Victor Rossi, Katie Conrad, Josephine Hernandez Mena, Elaine Meslow, Amelia A. Fuller, Eduardo Narbona, Justen B. Whittall

Chemistry and Biochemistry

There are 129 red-flowered species in western North America that fit the hummingbird pollination syndrome. Theory predicts that these flowers should produce a specific red color that is conspicuous to hummingbirds but not to bees. In a few well-studied cases, red flowers can be produced with pelargonidin, cyanidin, or both—sometimes complemented with the addition of yellow carotenoids and sometimes not. Which pigment combinations are most common in California and whether they affect conspicuousness to hummingbirds and bees remain unknown. To determine the taxonomic distribution of the pigments responsible for red hummingbird-pollinated flowers, we quantified the color of 36 red-flowered species …

Identification Of Subtypes Of Post-Stroke And Neurotypical Gait Behaviors Using Neural Network Analysis Of Gait Cycle Kinematics, Andrian Kuch, Nicolas Schweighofer, James M. Finley, Alison Mckenzie, Yuxin Wen, Natalia Sánchez

Physical Therapy Faculty Articles and Research

Gait impairment post-stroke is highly heterogeneous. Prior studies classified heterogeneous gait patterns into subgroups using peak kinematics, kinetics, or spatiotemporal variables. A limitation of this approach is the need to select discrete features in the gait cycle. Using continuous gait cycle data, we accounted for differences in magnitude and timing of kinematics. Here, we propose a machine-learning pipeline combining supervised and unsupervised learning. We first trained a Convolutional Neural Network and a Temporal Convolutional Network to extract features that distinguish impaired from neurotypical gait. Then, we used unsupervised time-series k-means and Gaussian Mixture Models to identify gait clusters. We tested …

A Tax Friendly Approach To Agrivoltaics, Avery S. Younis

Richmond Journal of Law & Technology

The first reported agrivoltaic farm experiment was performed on lettuce crops in 2013 in Montpellier, France. Ground-mounted solar panels were co-located with either food crops or livestock to simultaneously engage in agricultural activities while producing energy. This dual purposing of land is called agrivoltaics. Agrivoltaic projects are promising because the co-location aids with food production, renewable energy production, and preservation of natural resources. In America, the agricultural industry is supported by a myriad of policies protecting and benefitting farmers. One such benefit comes from current use programs. Many states offer current use programs in which agricultural land is assessed and …

Doctors Playing Lawyers: Lessons For Professional Regulation In Crisis, Rebecca H. Allensworth

Vanderbilt Law School Faculty Publications

When someone gets in legal trouble in America, their case is almost invariably decided by a lawyer (a judge), lay people (a jury), or a combination of the two. Professional discipline, however, is a giant unexplained exception. In professional discipline matters, accusations of dangerous or incompetent practice are decided, usually in the first instance but always in the last, by state licensing boards composed of other members of the accused’s profession. These licensing boards wield immense power as labor regulatory institutions, covering ten times as many American workers as the minimum wage and more workers than private and public sector …
