(2008-07-31)Department: PhysicsAngular correlations of prompt gamma-rays emitted from fission fragments allow the study of a variety of properties over a wide range of neutron rich nuclei. The method for angular correlations presented in this work was ...
-
(2016-04-12)Department: PhysicsIn chapter 1, we determine the masses, radii and temperatures of the eclipsing binary V578 Mon, a detached system of two early B-type stars in the Rosette Nebula, to better than 5% accuracy. We compare these measurements ...
-
(2018-04-18)Department: PhysicsEclipsing Binary stars (EBs) have long provided essential calibrations to stellar astrophysics and distance measurements. Recently, modern space-survey missions have allowed for determining the fundamental parameters of ...
-
(2020-05-14)Department: PhysicsIntercalation, the process of inserting atoms or molecules into host materials, has been extensively researched in graphite for energy storage and reaction catalysis applications. The recent ability to isolate graphite ...
-
(2017-04-05)Department: PhysicsIn the series of morphogenetic events that are required for Drosophila development, some of the most dramatic are those that involve the coordinated movement of the germband and amnioserosa, two epithelia that remain ...
-
(2015-04-19)Department: PhysicsOLTARIS, the On-Line Tool for the Assessment of Radiation In Space, is a one-dimensional nuclear transport code developed and utilized by NASA scientists to “study the effects of space radiation on shielding materials, ...
-
(2012-12-12)Department: PhysicsDorsal closure is an important morphogenetic event in the embryogenesis of Drosophila melanogaster and serves as a useful model system for studying wound healing, palatogenesis, and neural tube closure in vertebrates. ...
-
(2007-12-05)Department: PhysicsThe aim of the research described in this thesis was to study basic mechanisms of functional magnetic resonance imaging (fMRI) and to develop an improved understanding of the Blood Oxygen Level Dependent (BOLD) effect. In ...
-
(2007-12-07)Department: PhysicsIn the research described, we developed methods and protocols for high-spatial resolution functional magnetic resonance imaging (fMRI) of cortical activity in the brains of anesthetized non-human primates with sub-millimeter ...
-
(2018-09-20)Department: PhysicsThis work applies novel inverse modeling techniques to both chemical kinetics in lab-on-chip devices and cell mechanics in developing Drosophila embryos. The aim is to describe these systems quantitatively; to compare ...
-
(2012-12-12)Department: PhysicsDisruption of the normal heart rhythm can lead to a chaotic cardiac dynamic driven by the multiple scroll waves. If ventricular fibrillation (VF) develops, the cardiac intrinsic control system is unable to terminate it, ...
-
(2002-11-03)Department: PhysicsThis dissertation describes research on the application of intense, tunable, ultrafast lasers to studies of the silicon-dielectric system. Recently developed and now commercially available ultra-fast lasers are excellent ...
-
(2022-09-09)Department: PhysicsEpithelial wound healing is a vital biological process that involves the coordination of cells across a wounded tissue. Cells must be able to integrate both physical and chemical signals resulting from a wound in order to ...
-
(2010-03-23)Department: PhysicsWe report the observation of coherent acoustic phonon oscillations in GaSb(20 nm)/GaAs near the band gap of GaAs at room temperature. A photogenerated longitudinal acoustic phonon wave travels from the top surface of GaSb ...
-
(2014-03-27)Department: PhysicsCharacterization and modeling magnetic flux transport within the surface layers of the Sun are vital to explaining the 11 year sunspot cycle. I have characterized the differential rotation (DR) and meridional flow (MF) ...
-
(2018-09-18)Department: PhysicsRelativistic Heavy Ion Collisions help us explore the broad field of Quark Gluon Plasma. At a fundamental level, the partons or the quarks and gluons are involved in producing the final state hadrons, which help understand ...
