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. ...
Micro Programmable Object Navigation Gadget (micro-PONG) for Studying Electroosmotic Flow in PDMS Microchannel
(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 ...
Dark radiation from particle decays during big bang nucleosynthesis
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-04)
Cosmic microwave background (CMB) observations suggest the possibility of an extra dark
radiation component, while the current evidence from big bang nucleosynthesis (BBN) is more
ambiguous. Dark radiation from a decaying ...
Measurement of Energy Spectrum of Electrons Field-Emitted from Diamond Field-Emitter Arrays
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)
A retarding mesh analyzer was used to measure the electron energy spectrum field emitted from a single tip of a Diamond Field Emitter Array. The emission was dominated by adsorbed gas
atoms and molecules on the surface ...
Simulations of Nano-Structures in Time Dependent External Fields
(Vanderbilt University. Department of Physics and Astronomy, 2013-04-22)
Time Dependent Density Functional Theory is used to probe the
structure of matter. Coulomb explosion of small hydrocarbons driven by
strong laser pulses and electron holography of molecules are studied
in a theoretical ...
An anomalous measurement of delta m31 squared from neutrino oscillations at the Daya Bay Reactor Neutrino Experiment
(Vanderbilt University. Department of Physics and Astronomy, 2013-04-22)
In 2012, the collaboration overseeing the Daya Bay Reactor Neutrino
Experiment announced results which determined the magnitude of the mixing
angle \theta_{13} with unprecedented precision. However, no attempt was made
in ...
Multipole mixing ratios of transitions out of high spin gamma vibrational states in neutron rich Mo, Ru isotopes
(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 ...
Investigation of Electroosmotic Flow in Various Microfluidic Structures
(Vanderbilt University. Dept. of Physics and Astronomy, 2010-04)
Enclosed microfluidic devices provide excellent systems for the study of
biological processes such as cell-cell, paracrine, and autocrine signaling
systems. By minimizing the fluid volume within the chambers, ...
Reflection and rotation for three dimensional microscopy of live cells
(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 ...
Engineering a perfusion-enabled mechanical compressor for long-duration immobilization and microscopy of cells and small organisms
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)
The study of living specimens is essential to the understanding of
organismal behavior. Unfortunately, a major difficulty in the study of
live organisms is that many move in and out of the field of view or
focal plane ...
