This thesis describes fundamental photophysical studies of quantum dot (QD)-molecule complexes, aimed at discovering strategies for enhancing the efficiency of QD-photocatalyzed and QD-sensitized multi-electron catalytic reactions, for the purpose of solar fuels production. Photosensitization of molecular catalysts that are active for reactions such as the reduction of carbon dioxide or...
Store-operated Ca2+ entry (SOCE) is a principal mechanism for generating cellular Ca2+ signals. Store-operated Ca2+ release-activated Ca2+ (CRAC) channels serve an essential role in generating Ca2+ elevations needed for transcriptional, enzymatic, and secretory effector cascades in many cell types. CRAC channels, comprised of the ER Ca2+ sensor STIM and the...
In monolayer materials with a honeycomb-like lattice an emergent degree of freedom arises for charge carriers corresponding to their valley index. Due to spatial inversion asymmetry and the presence of strong spin-orbit coupling, this valley degree of freedom strongly affects the optoelectronic properties of carriers in monolayer transition metal dichalcogenides...
Platelets are circulating anucleate discs derived from megakaryocytes, and play major roles in hemostasis, inflammation, thrombosis, and vascular biology. Multi-phase culture systems for inducing in vitro platelet production from mature megakaryocytes have been explored to allow progenitor expansion, megakaryocyte maturation, and promotion of platelet formation and shedding. In this thesis,...
Abstract The overall purpose of this paper is to reconsider the narrative usage and function of a literary phenomenon like ‘opposition/tension/contradiction.’ Throughout my analysis of Alain-Robbe Grillet’s La jalousie, Chloé Delaume’s J’habite dans la television and Jean Genet’s Le Balcon I was focused on investigating the use of this phenomenon...
This dissertation traces the rise and the demise of the Amerasian in the years roughly set by the Amerasian Immigration Act (1950-1982). I argue that an Amerasian is not simply an individual fathered by a US servicemen in Asia, nor is it just a racial descriptor used to term mixed...
Transcription is tightly regulated to ensure genes are appropriately expressed both temporally and spatially. This tight regulation governs various processes within the cell, such as differentiation and cell identity, cellular maintenance, and dynamic responses to external signals. Transcription factors (TFs) coordinate these various gene programs and in particular, are key...
This dissertation presents two projects with the goal of understanding how to quantitatively describe biological data, particularly data that is highly dynamic. The first study presents an improved quantitative tool for the analysis of particulate trajectories. Particulate trajectory data appears in several different biological contexts, and the majority of analyses...
Endothelial cells (ECs) require glycolysis for proliferation and migration during angiogenesis; however, the necessity for the mitochondrial respiratory chain during angiogenesis is not known. In this study, we report that inhibition of respiratory chain complex III impairs proliferation, but not migration of ECs in vitro by decreasing the NAD+/NADH ratio....
Herpes simplex encephalitis (HSE) is a rare and severely debilitating life-threatening disease caused by herpes simplex virus type 1 (HSV-1) infection of the human central nervous system (CNS). The severe and often fatal outcomes of HSE contrast starkly with the more frequent and largely benign consequences of herpes labialis. Whole...
