The work presented in this dissertation examines the interplay between electron transfer reactions and electron spin in photoactive organic molecules. Organic compounds that undergo electron transfer reactions after absorbing light are important in natural photosynthesis, photobiology, and synthetic photovoltaics. These electron transfer reactions depend on the spin states of the...
Microkinetic modeling is a powerful tool for creating dynamic and quantitative descriptions of complex systems. These detailed mechanistic models compliment experimental techniques and provide an ability to achieve deeper insights into chemical processes where numerous intermediates are highly reactive and difficult to quantify in the laboratory. This thesis discusses the...
Humans possess the ability to infer and track mental states, which allows for successful interaction in the social world. The collection of processes and representations that makes this possible is referred to as a theory-of-mind (ToM). A large body of work has examined how these abilities develop from infancy to...
Ions dissolved in solution are known to interact in remarkable ways with charged Langmuir monolayers. The organic monolayer can be used as a molecular template for ordered nucleation of inorganic crystals (biomineralization) and functional nanoparticles. However, the clear majority of experiments demonstrating these behaviors have been performed with divalent ions....
The goal of science education is to prepare students to make decisions about the complicated socioscientific issues that are an inescapable part of modern life, from personal medical decisions to evaluating a political candidate's environmental platform. We cannot expect adults to maintain a deep conceptual understanding of the current state...
Large projection neurons of the cerebellar nuclei (CbN cells), whose activity generates movement, are inhibited by Purkinje cells and excited by mossy fibers. The high convergence, firing rates, and strength of Purkinje inputs predict powerful suppression of CbN cell spiking, raising the question of what activity patterns favor excitation over...
This project examines how early modern writers mobilize race as a vehicle for investigating far-reaching epistemological questions about the limits and parameters of human knowledge. While dominant trends in early modern race studies have focused on racial knowledges or particular identifications or formulations of human difference, I break new ground...
This dissertation explores how the environment shapes energy expenditure and cardio-metabolic disease risk by investigating multiple timescales of adaptation to cold stress among the Yakut, an indigenous circumpolar population. This study pursues three main objectives. First, the adaptive and health significance of brown adipose tissue (BAT) is explored by examining...
In fish, caudally propagating waves of neural activity produce muscle bending moments. These moments, coupled with forces due to the body's elastic properties and forces due to fluid-body interactions, determine the deformation kinematics for swimming. Fully resolved simulations of neurally-activated swimming can be used to decode activation patterns underlying observed...
Bacterial biofilms are aggregates of cells that adhere to nearly any solid-fluid interface. While many have harmful effects, such as industrial damage and nosocomial infections, certain biofilm species are now generating renewable energy as the fundamental components of Microbial Fuel Cells (MFCs). In an MFC, bacteria consume organic waste and,...
