(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 ...
-
(2007-09-13)Department: PhysicsMicrocalorimetry is an established technique in the biological sciences for determining energy generation and consumption. With recent developments in microfabrication techniques, nanocalorimeters or even picocalorimeters ...
-
(2013-04-09)Department: PhysicsMagnetic Resonance Spectroscopy (MRS) is a powerful technique that can potentially be used to measure metabolite concentrations in the brain non-invasively. However, the available signal-to-noise ratios (SNR) of MR spectra ...
-
(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 ...
-
(2019-04-03)Department: PhysicsIn continuation of nuclear structure studies in the neutron-rich rare earth region the isotopes of 157Sm, 163Gd and 163Tb have been investigated to establish, or expand, the ground state and low energy bands. Investigations ...
-
(2017-07-31)Department: PhysicsGraphene is the simplest crystalline membrane and therefore the ideal material to test mechanics at the ultimate, atomic thickness limit. It is well known from experiments performed at high stress that graphene is one of ...
-
(2016-12-01)Department: PhysicsWe present three experiments designed to explore the physics of nanostructured materials in nonlinear optics. We utilize both photon and electron-beam excitations on systems with local densities of states specifically ...
-
(2014-04-08)Department: PhysicsFramework for ab initio calculation of nonlinear optical susceptibilities on the level of Real Time Time Dependent Density Functional Theory was developed and implemented in high performance numerical codes. Methodology ...
-
(2008-07-21)Department: PhysicsTraditional particle sensing schemes are based on the resistive-pulse sensing technique. A non-conducting particle displaces a volume of electrolyte, equal to its own volume, from a sensing channel when it flows through. ...
-
(2018-08-29)Department: PhysicsIdentified particle spectra provide an important tool for understanding the particle production mechanism and the dynamical evolution of the quark-gluon plasma (QGP) created in relativistic heavy ion collisions. Studies ...
-
(2010-08-19)Department: PhysicsThis dissertation was completed by analyzing gamma-gamma-gamma coincidence data of 252Cf obtained with Gammasphere. A few neutron-rich nuclei in three different mass regions have been studied by establishing their level ...
-
Observation of Collective Behavior in High-Multiplicity Proton-Gold Collisions with PHENIX at RHIC (2018-03-19)Department: PhysicsQuark Gluon Plasma (QGP) is an extremely hot and dense state of nuclear matter in which the quarks and gluons are not confined into hadrons. QGP existed in the first microsecond of the Universe and presently, it is produced ...
-
(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 ...
-
(2010-03-25)Department: PhysicsThis thesis addresses the origin of the High Velocity Clouds (HVCs) observed around the Milky Way and other nearby galaxies. Such clouds are likely created through a combination of galactic fountains, galaxy interactions, ...
-
(2012-04-19)Department: PhysicsI studied the effectiveness of the MultiTrack Validator to determine whether or not it could distinguish between primary and secondary vertexes in the Phase 1 Tracker Upgrade of the Super Large Hadron Collider, as finding ...
-
(2015-07-21)Department: PhysicsThe administration of open radioactive sources to systemically target malignant cells has become a desirable treatment option for several types of cancer. However, patients receiving this form of radiation therapy often ...
-
(2015-06-29)Department: PhysicsRadiation dose calculations are essential to understanding the balance between the benefits and risks of diagnostic imaging procedures. Red marrow is also a highly radiosensitive organ and of great interest especially for ...
