Phase transitions occur in such diverse and important systems as ferromagnets, liquid crystals and the early Universe. The dynamics of phase transitions such as these have been studied for decades, but the analytical models still need a great deal...
This thesis focuses on the emergence of universal dynamical scaling in quantum critical spin systems driven out of equilibrium, with emphasis on quench dynamics which involves isolated standard critical points, multi-critical points, and...
Magneto-spectroscopy is used to characterize the confinement properties of strain-induced quantum wires and dots. The wires and dots are low energy regions in an ordinary GaAs/AlGaAs quantum well that are formed when microscopic...
Many alkaloids of biological importance have the 11H-pyrido (4,3,2-mn) acridine ring structure such as cystodytin and amphimedine. It would be desirable to find an effective way to synthesize a wide variety of these compounds using a single...
While Cherenkov emission was discovered more than eighty years ago, the potential applications of imaging this during radiation therapy have just recently been explored. With approximately half of all cancer patients being treated by radiation at...
Across mammalian species, adolescence is characterized by a unique combination of cognitive, behavioral and neurobiological changes. Behavioral tendencies observed during this period promote a variety of flexible interactions with the surrounding...
Visual pigments. ; Cellular signal transduction. ; Rhodopsin. ; G proteins. ; Phosphorylation. ; Photoreceptors. ; Retinal degeneration.
Arrestins are regulatory proteins that participate in the termination of G protein-mediated signal transduction. The major arrestin in the Drosophila visual system, Arrestin 2 (Arr2), has been demonstrated to be essential for the termination of the...
Nitric oxide -- Analysis. ; Dithiocarbamates. ; Iron compounds. ; Organonitrogen compounds. ; Electron paramagnetic resonance spectroscopy.
Nitric oxide is synthesized by living organisms and plays important roles in circulatory, neurological, and immune function. Nitric oxide can also play pathophysiological roles, depending on the amount of the molecule, the presence of other species...
CYP3A has the highest affinity for oxidation of Acetaminophen (APAP) with a Km close to the concentration observed in human serum after administration of therapeutic doses of APAP. CYP3A may be induced by numerous drugs as well as alcohols. We...
The processes by which nonlinear physical systems approach thermal equilibrium is of great importance in many areas of science. Central to this is the mechanism by which energy is transferred between the many degrees of freedom comprising these...
Epilepsy is the most common neurological disorder in children, with an incidence of 100 per 100,000 children per year. Recurrent seizures during this period in life are often distressing to the individual and the family, but arguably the most...
