Tang, Lin (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 ...
-
Zhang, Na (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 ...
-
Semmineh, Natenael Berhanu (2014-04-27)Department: PhysicsThe systematic investigation of susceptibility-induced contrast in MRI is important to improve our understanding of the influence of tissue microstructure on dynamic susceptibility contrast (DSC)-MRI derived perfusion data. ...
-
Colvin, Daniel Christopher (2009-11-09)Department: PhysicsDiffusion-weighted magnetic resonance imaging (DW-MRI) is a noninvasive imaging technique that can be used to quantify the rate of self-diffusion of water molecules. In biological tissues the mobility of water molecules ...
-
Teran Balbuena, Edgar (2003-04-14)Department: PhysicsThe description of the properties of nuclei far from stability presents a big challenge in Nuclear Physics theory. It demands the development of sophisticated algorithms suitable for describing the complex many-body ...
-
Fong de los Santos, Luis E (2005-04-06)Department: PhysicsDevelopment of a scanning superconducting quantum interference device (SQUID) microscope system with interchangeable sensor configurations for imaging magnetic fields of room-temperature (RT) samples with sub-millimeter ...
-
Escamilla Roa, Jesus (2009-01-02)Department: PhysicsA new quantitative and numerically efficient model of the most recent, more finely binned in energy, Super Kamiokande experiment is developed. By reproducing an analysis of this data performed by the experimentalist, ...
-
Janve, Vaibhav Anil (2015-04-17)Department: PhysicsConventional MRI is sensitive to detect brain abnormalities non-invasively through excellent contrast generated by variation in relaxation times and water proton density. However, conventional MRI lacks the specificity and ...
-
Song, Liguo (2004-04-05)Department: PhysicsWith improved Z-Burst model for the new cosmology and reasonable distribution of the neutrino cosmic ray sources, the signatures of the Z-Burst absorption dip and the contributing parameters are investigated through numerical ...
-
Gomez Maqueo Chew, Yilen (2010-08-05)Department: PhysicsThis thesis presents the analysis of two double-lined, detached, eclipsing binary systems associated with the young Orion Nebula Cluster, 2MASS J05352184–0546085 and Parenago 1802. We present a multi-band, multi-epoch ...
-
Rodriguez, Joseph Enrique, Jr. (2016-03-29)Department: PhysicsThe circumstellar environments of young stellar objects (YSOs) involve complex dynamical interactions between dust and gas that directly influence the formation of planets. However, our understanding of the evolution from ...
-
Guo, Lei (2004-04-14)Department: Physics<font size=+1> The reaction γ p → π<sup>+</sup> K<sup>-</sup>K<sup>+</sup>n has been investigated at Jefferson Lab using a tagged photon beam with an energy range of 3-5.47 GeV. A narrow baryon state with strangeness ...
-
Monsue, Teresa Antoinette (2018-11-27)Department: PhysicsActive regions on the Sun are abundant with a variety of waves that are both acoustically helioseismic and magnetohydrodynamic in nature. The occurrence of a solar flare can disrupt these waves, by excitation of these waves ...
-
Cogswell, Bernadette Kafwimbi (2014-10-28)Department: PhysicsWe conducted an updated global analysis of neutrino oscillation data using alternative bounds on the mixing angle theta-13 to determine the best fit mixing angles theta-13 and theta-23, the mass- squared difference ∆m_32^2, ...
-
Holmes, Martha J (2009-04-22)Department: PhysicsThis thesis summarizes the research I have done during my graduate tenure at Vanderbilt University. The core of the thesis is a model of glueballs as tightly knotted or linked chromoelectric flux tubes. The model is based ...
-
Bodnarik, Julia Gates (2013-04-17)Department: PhysicsAsteroids are remnants of the formation of the Solar System and provide insight into its formation, evolution and how life may have begun. An important issue is determining which meteorite composition is representative ...
