The corrected apparent diffusion coefficient (Dapp), kurtosis coefficient (Kapp), distributed diffusion coefficient (DDC), and intravoxel water molecular diffusion heterogeneity (α) were calculated from the corresponding non‐Gaussian diffusion model. The T1rho value was calculated using a monoexponential...
Intravoxel Incoherent Motion model; BE, Biexponential model; SE, Stretched Exponential model; DKI, Diffusion Kurtosis Imaging; BPH, benign prostatic hypertropia; SD, standard deviation; GS, Gleason Score; ROI, region of interest.
Five non-Gaussian diffusion models were implemented in the application: diffusion kurtosis imaging, intravoxel incoherent motion, gamma distribution, truncated and stretched-exponential. Parametric maps and region-of interest (ROI) parametric values were obtained for each model. In order to fit the ...
Brownian yet non-Gaussian diffusion has been recently reported in a huge number of biological and soft matter systems. Meanwhile, an archetypal theoretical model called 'diffusing diffusivities' is proposed to interpret it. Based on this spirit of diffusing diffusivities, we extend the original diffusi...

Because of the artificial heating time, heating temperature and particularities of the standard sample in the laboratory, some differences could exist between the He thermodynamic model established by the thermal diffusion experiments and the actual geological conditions. The most significant differences ...
From the transient confinement to a random walk It is natural to suspect that the diffusion dominated by the transient confinement is a type of random walk, which is even suggested by the term "hop diffusion". We will derive the random walk which corresponds to the model of the ...

In the original model of membrane diffusion5, the cell membrane was considered as a continuum fluid layer, which is true only if the membrane is homogenous and the diffusing particle is much larger than the surrounding membrane molecules. For AChRs, however, their size is comparable to that ...
