Fall 2016
Laser plasma interactions with high intensity laser pulses can produce extremely high magnetic fields in the MG range. In particular, the application of circularly polarized or orbital angular mode (OAM) laser beams can be used to generate such large fields using the Inverse Faraday Effect (IFE)....

Inverse resonance absorption in an inhomogeneous magnetized plasma
1985
Barr, H. C., Rankin, Robert. , Boyd, T. J. M., Gardner, G. A.
The linear mode conversion of a plasma wave to a light wave in a magnetized plasma has been examined theoretically and by computer simulation. This conversion is the inverse of resonance absorption exhibiting an identical dependence on magnetic field and density scale length with an optimum...

Both short and long pulse laser plasma interactions are investigated by theoreti- cal analysis and modern computational techniques. An extensive set of simulations of short pulse laser plasma based particle accelerators are performed with the aim of improving performance and diagnostics of the...

Fast ignition (FI) decouples the compression and ignition in normal Inertial Confinement Fusion schemes, and can rely on hot electron transport to ignite the compressed core. In order to study electron transport, characteristic K-alpha X-ray emission from copper tracer layers is often employed. A...

In this thesis we present Particle-in-Cell (PIC) plasma simulations designed to model large amplitude whistler waves. There are significant nonlinear effects that arise due wave-wave and wave-particle interactions. There are two related sections to this report: one investigating the evolution of...

Tikhonchuk, V. T., Frycz, P., Samson, J. C., Rankin, Robert
We present theory and numerical simulations of strong nonlinear effects in standing shear Alfven waves (SAWs) in the Earth's magnetosphere, which is modeled as a finite size box with straight magnetic lines and (partially) reflecting boundaries. In a low beta plasma it is shown that the...

Rankin, Robert, Tikhonchuk, V. T.
We describe nonlinear resonance absorption of compressional Alfven waves in a model magnetosphere. It is shown that the ponderomotive force of excited standing shear Alfven waves can lead to nonlinear saturation and spatial structuring of field line resonances and that in low-beta plasmas...

Optimization, adaptation and application of protein misfolding cyclic amplification to detection of prions in blood plasma
DownloadFall 2010
The PMCA assay was optimized for adaptation to low level detection of PrPSc in hamster plasma. Evaluation of numerous key variables of the PMCA assay led to an optimized protocol capable of ~3 log10 amplification after 32 cycles (two 16 hour rounds). When commercially purchased normal hamster...

Putative ante-mortem indicators of Alzheimer’s dementia: Analysis of fluid biomarker and neuroimaging studies
DownloadSpring 2019
Dementia is a clinical state, characterized by symptoms indicative of deterioration of memoryand cognitive functions that interferes with social or occupational functioning. According to2018 statistics, around 50 million people are living with dementia, and this number will increaseto 131.5...
