Diffusion magnetic resonance imaging (dMRI) measures the diffusion (i.e. random molecular motion) of water. Since the motion of water is inhibited by cellular membranes, dMRI provides insight into the microstructural characteristics of the tissue. However, distinguishing between small anatomical...

Structural brain changes occur in a complex manner throughout life, and understanding healthy brain development is crucial for the study of brain abnormalities in various conditions. Diffusion tensor imaging (DTI) is an advanced magnetic resonance imaging technique that provides information about...

Rankin, Robert, Tikhonchuk, Vladimir T., Samson, John C.
Dispersive effects in field line resonances (FLRs) are discussed in the context of potential structures, parallel currents, and auroral density cavities observed by the FAST satellite. Our model includes the Earth's dipole magnetic field, and accounts for electron inertia, electron thermal...

The adiabatic drift-resonant interaction between relativistic, equatorially mirroring electrons and narrowband, Pc 5 ultra low frequency (ULF) waves in the magnetosphere is investigated using a time-dependent magnetohydrodynamic (MHD) wave model. Attention is focused on the effect of a ULF wave...

Recent simulation results have revealed that energetic electron bursts are produced cyclically at the shock reformation period upstream of reforming shocks and are qualitatively very different from the continuous beam expected from time-stationary shocks (Yuan et al., 2007a). This paper extends...

A new interactive M-I coupling model that describes the dynamic interaction between magnetospheric dispersive waves, compressional modes, and auroral electron precipitations is applied to investigate the geomagnetic electromagnetic pulsations observed in Earth's magnetosphere in terms of...

Rankin, Robert, Watt, Clare E. J.
We investigate parallel electron acceleration due to inertial Alfven wave pulses in the presence of Lorentzian ( kappa) distribution functions which possess high-energy tails. A linear kinetic dispersion relation for inertial Alfven waves is derived whose solutions are used to guide the analysis...

Estimating Diffusion Coefficients And Visualizing Interactions In Propane-Heavy Oil Systems
DownloadSpring 2019
Unconventional oil (mainly heavy oil, extra heavy oil and bitumen) represents a significant share of global oil reserves. Due to their high viscosity, efficient recovery of oil from these reserves is challenging and remains an issue of ongoing global research. Thermal recovery methods are...

We use an evolutionary approach to find “most appropriate” dispersal models for ecological applications. From a random walk with locally or nonlocally defined transition probabilities we derive a family of diffusion equations. We assume a monotonic dependence of its diffusion coefficient on...

Folding of biomolecules is an important problem in structural biology. The physical folding can be projected as a diffusive search over an energy landscape whose dimensions scale by all the internal degrees of freedom which a biomolecule possesses. To explore this idea, folding is studied from...
