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...

Rankin, Robert, Gardner, L. R. T., Barr, H. C., Boyd, T. J. M.
The effects of a magnetic field on the Raman and two‐plasmon decay instabilities are studied in the region of the quarter‐critical density of laser produced plasmas where both are coincident. Two‐plasmon decay of the incident extraordinary wave into two upper‐hybrid waves may now occur in the...

Watt, Clare E. J., Wright, D. M. , Rankin, Robert, Rae, I. Jonathan
We present self-consistent kinetic simulations of the electron response to finite duration shear Alfven wave pulses in a magnetized plasma. In Earth's magnetosphere, the evidence suggests that parallel electric fields in inertial scale shear Alfven waves can accelerate electrons in the...

Self‐consistent wave‐particle interactions in dispersive scale long‐period field‐line‐resonances

Rankin, Robert, Samson, John C., Watt, Clare E. J.
Using 1D Vlasov drift-kinetic computer simulations, it is shown that electron trapping in long period standing shear Alfvén waves (SAWs) provides an efficient energy sink for wave energy that is much more effective than Landau damping. It is also suggested that the plasma environment of low...

Two flybys of Mercury by the NASA MESSENGER spacecraft on January 14 and October 6, 2008 provide insight into the spatial distribution of the heavy ion exosphere around the planet. The relatively quiet solar wind conditions and interplanetary magnetic field (IMF) orientation allow us to compare...

Zank, G. P., Lu, J. Y., Rankin, Robert, Marchand, Richard
The propagating source method for solving the time-dependent Boltzmann equation describing particle propagation in a magnetically turbulent medium is extended to a more realistic case that includes focusing and adiabatic deceleration. The solutions correspond to beam propagation in the solar...

Theory and Application of Thomson Scattering to Particle Transport and Magnetic Field Measurements in Laser-Produced Plasmas
DownloadSpring 2023
The particle transport, plasma currents, and magnetic fields were investigated in laboratory plasmas, both with the Optical Thomson Scattering (OTS) diagnostic and in theory and numerical simulations. %despite the presence of hot ion tails, which would be more suppressed by collisions in real...

The effect of partial coherence of a probe on the spectrum of Thomson scattered radiation from plasma is investigated. The coherence of a probe is described in terms of the electric field Gaussian correlation function of the finite correlation time (longitudinal coherence) and the finite...
