Early Detection of Malignant Transformation in Resected WHO II Low-Grade Glioma Using Diffusion Tensor-Derived Quantitative Measures. [PDF]
PLoS ONE, 2016 Here, we retrospectively investigate the value of voxel-wisely plotted diffusion tensor-derived (DTI) axial, radial and mean diffusivity for the early detection of malignant transformation (MT) in WHO II glioma compared to contrast-enhanced images.Forty ...

Modeling desorption kinetics of a persistent organic pollutant from field aged sediment using a bi-disperse particle size distribution [PDF]
, 2010 Purpose With the predicted climate change, it is expected that the chances of river flooding increase. During flood events, sediments will resuspend and when sediments are polluted, contaminants can be transferred to the surrounding water.

Nonlinear aggregation-diffusion equations: radial symmetry and long time asymptotics [PDF]
Inventiones Mathematicae, 2016 We analyze under which conditions equilibration between two competing effects, repulsion modeled by nonlinear diffusion and attraction modeled by nonlocal interaction, occurs.

Macromolecular diffusion in intact, degraded and crosslinking-augmented intervertebral discs
Journal of Biomechanical Science and Engineering, 2017 Injection of macromolecular anabolic enzymes is a promising treatment for disc degeneration. However, macromolecular diffusion within the degraded or crosslinking-augmented discs remains unclear.

Radial propagation in population dynamics with density-dependent diffusion
, 2013 The population dynamics that evolves in the radial symmetric geometry is investigated. The nonlinear reaction-diffusion model, which depends on population density, is employed as the governing equation for this system. The approximate analytical solution

Characteristic times for radiation belt drift phase mixing
Frontiers in Astronomy and Space SciencesImpulsive radial transport events occurring in the radiation belts leave lasting marks in the form of drift echoes, that is, energy-dependent drift phase structures in the radiation belts that evolve at the drift frequency.

Quantifying the effect of magnetopause shadowing on electron radiation belt dropouts [PDF]
Annales Geophysicae, 2013 Energetic radiation belt electron fluxes can undergo sudden dropouts in response to different solar wind drivers. Many physical processes contribute to the electron flux dropout, but their respective roles in the net electron depletion remain a ...

Empirical comparison of diffusion kurtosis imaging and diffusion basis spectrum imaging using the same acquisition in healthy young adults [PDF]
, 2017 As diffusion tensor imaging gains widespread use, many researchers have been motivated to go beyond the tensor model and fit more complex diffusion models, to gain a more complete description of white matter microstructure and associated pathology.
