Influence of patient size on dose to female breast tissue during routine computed tomography scans (Vanderbilt University. Dept. of Physics & Astronomy, 2008-04-21)Monte Carlo methods are well suited to the evaluation of radiation transport phenomena. The scalable phantoms employed in this project permitted rapid creation of three models of similar geometry, but different body habitus. ...

(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)Precise control of fluid delivery in analytical devices may be achieved by harnessing electroosmotic flow (EOF) in oxidized poly(dimethylsiloxane) microfluidic channels fabricated via soft lithography. However, the ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2010-04-27)Current models of nuclear structure describe nuclear states in terms of collective vibrations and rotations of a ground state. - One such quadrupole vibrational band is the gamma-band formed by vibrations of the short ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2016-05-02)A Fano resonance is an asymmetric, resonant scattering phenomenon which occurs in a multitude of fields, such as atomic physics, nuclear physics, nonlinear optics, and nanophotonics. The Fano resonance is a many-particle ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2008-04-20)We use projected number density profiles of galaxy groups to investigate the relationship between galaxy group structure and dark matter structure within halos. We primarily study a specific model of how galaxies populate ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)I develop a perturbation theory for resonant frequency shifts caused by thin layer of material added to dielectric systems. This development can be used to effectively model photonic surface-sensing systems, which use ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2019)New massive spin-2 particles are predicted in theoretical extensions to the Standard Model (SM) attempting to solve the hierarchy problem. Such theories postulate that gravity is diluted compared to the other fundamental ...
-
(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04)While this project did not successfully produce a working photovoltaic device, significant progress has been made in the individual components of the system. This thesis describes two of those components: fabrication of ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2016-05-02)The energy of the Ps2- (three electrons and two positrons or vice versa) system and all possible fragmentations are calculated in a magnetic field in their M=0 states using the stochastic variational method with a deformed ...
-
(Vanderbilt University. Department of Physics and Astronomy, 2014-04)We examine models of quintessence in which a minimally-coupled scalar field phi evolves near a local extremum of its potential V ( phi) at phi_*. Assuming that (1/V )(dV/dphi) is small and w ~ -1, we Taylor expand the ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-05-04)Density functional theory is utilized in real-time, real-space simulations of LEED measurements and attosecond electron scattering. For LEED measurements, we find that our simulation results agree well with experimental ...
-
(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04-18)Confocal scanning laser microscopy and multiphoton microscopy provide 3D data from biological specimens, but with limited z-axis precision. Multiple microscale mirrors can be used to obtain more accurate 3D data on living ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-04)Rotation period distributions for older open clusters are difficult to obtain because of the general scarcity of clusters with ages greater than 200 Myr, as well as the challenge of measuring rotation periods for less ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2016-05-18)Using data from the Kilodegree Extremely Little Telescope (KELT) project, we performed a survey of 2028 known M Dwarf stars in the KELT footprint for M-M Dwarf eclipsing binaries (EBs). After searching 2028 Mdwarf ...
