- Advancement of magnetic resonance poroelastography for applications in brain imaging / by Adam J. Pattison.
- Brain tissue mechanics are an important biomarker for neurological disorders, yet methods to obtain tissue information yield inconsistent conclusions. These techniques can be invasive or require excised tissue, where tissue function is altered from...

- A computational study of radio relics in galaxy cluster mergers / by Dane Patrick Owen.
- Radio relics are extended regions of synchrotron radio emission that have been found in the outskirts of a few dozen galaxy clusters. Relics are often associated with clusters undergoing merger activity. They are not associated optically with a...

- Crevasse detection in ice sheets using ground penetrating radar and machine learning / by Rebecca M. Williams.
- The purpose of this thesis is to describe methods for detecting hidden crevasses on glaciers in Polar regions. Crevasses form in ice sheets as a result of forces imposed upon the brittle ice. The crevasses are hidden from view by bridges of soft...

- Spectroscopic analyses of type Ia supernovae / by Jerod Parrent.
- After decades of searching we have yet to find the progenitor systems for type Ia supernovae. In fact most of what we know about this homogeneous class of supernovae is from spectral features associated with the incinerated remains of the C+O white...

- Determining anthropogenic and natural controls on the global mercury cycle using lake sediment and ice cores ; by Samuel Adams Beal Jr.
- While anthropogenic emissions of the toxic element mercury (Hg) to the atmosphere are currently rising, major uncertainties remain in determining the relative impacts of anthropogenic activity and natural processes on the global Hg cycle. In this...

- Nerve growth factor and the septohippocampal system / by Lan Guo.
- Nerve growth factor (NGF), the prototypic neurotrophin, is well characterized for its pro-survival and growth effects in sympathetic and sensory neurons. Acting as a target-derived factor, NGF regulates the maturation of innervating neurons, and...

- Late glacial and holocene fluctuations of local glaciers and the Greenland Ice Sheet eastern and western Greenland / by Laura B. Levy.
- The Greenland Ice Sheet (GrIS) is responding sensitively to climate change and its meltwater has the potential to influence global sea level. Recently, large changes in the GrIS have occurred including increased velocities of outlet glaciers and...

- Ground and space observations of medium frequency auroral radio emissions / by Matthew C. Broughton.
- The auroral zone is a rich source of natural radio emissions that can be observed in space and at ground-level. By studying these waves, scientists can gain insight into the plasma processes that generate them and use the near-Earth space...
