The utilization of hydrofluoric acid for the preparation of silver vanadium oxide fluorides has been advanced for the synthesis of Ag<sub>4</sub>V<sub>2</sub>O<sub>6</sub>F<sub>2</sub> and Ag<sub>3</sub>VO<sub>2</sub>F<sub>4</sub>. Silver-rich metal oxide fluorides are important battery cathode materials due to the high reduction potential of silver vs. Li, which is made even higher by the incorporation...
Most organisms use rhythms of sunlight to synchronize their activity to the environment. These rhythms of activity are called circadian rhythms. The rhythms persist with near 24 hour periods when external synchronizing cues are absent. In mammals, the circadian clock is generated at the molecular level by a transcriptional/translational feedback...
This thesis contributes in two ways. First it describes a new framework for the systematic design of collective behaviors and solves a key stability issue under this design framework. In this thesis we apply this framework to solve three tasks in the swarm robotics field: connectivity maintenance, formation control and...
Sufficient vocal fold superficial hydration is indispensable to maintain normal vocal function and protect vocal fold epithelium against invasion of pathogenic agents. Vocal fold surface hydration is probably regulated by its electrophysiological properties. We hypothesized that the tight junction (TJ)-related paracellular barrier contributes to the maintenance of those properties. Therefore,...
Solder joint integrity is recognized as a key issue in the reliability of flip chip and ball grid arrays in integrated circuit packages. Significant reductions in the solder-joint interconnect size results in both the increased volume fraction of brittle intermetallics in the joint and joule heating and electromigration failure due...
T-cell activation is an essential step of the immune response, yet the cellular and molecular events underlying this complex process are not fully understood. Significantly, a comparative genome-scale transcriptional analysis of two T-cell subsets and the natural-mixed CD3+ population remains unexplored. Using microarrays, we investigated the temporal global transcriptional profile...
In this thesis we investigate the orbital evolution of planets in binaries.Unlike our own Solar System, at least one out of five planetary systems known to date is associated with additional stellar companions. Despite their large distances from the planetary systems, these stellar companions play an important role in significantly...
Research in cognitive and developmental psychology typically focuses on urban middle-class, European American populations. Although there has been a recent surge in psychological research that focuses on cultural variation (Cohen & Kitayam, 2007), little is known about the practices that support this variation. Knowledge about these practices is critical for...
Although chronic stress has been shown to be significantly associated with depression, this relationship has not received adequate attention, particularly in adolescent samples. One gap lies in the examination of whether particular domains of chronic interpersonal stress are uniquely related to risk for depression. Furthermore, the degree to which chronic...
Microarrays are powerful tools in gene expression assessment, protein profiling, and protein function screening, as well as cell and tissue analysis. With thousands of small array spots assembled in an ordered array, these small devices makes it possible to screen for multiple targets in a fast, parallel, high-throughput manner. The...
