diffusion weighted imaging uses the signal loss associated with the random thermal motion of water molecules in the presence of magnetic field gradients to derive a number of parameters that reflect the translational mobility of the water molecules in tissues. with a suitable experimental set-up, it is possible to calculate all the elements of the local diffusion tensor (dt) and derived paramet...

We demonstrate the level crossing phenomenon for fermions in the background field of the sphaleron barrier, by numerically determining the fermion eigenvalues along the minimal energy path from one vacuum to another. We assume that the fermions of a doublet are degenerate in mass, allowing for spherically symmetric ansätze for all of the fields, when the mixing angle dependence is neglected.

Abstract Modeling and predicting the information diffusion process on social platforms is a critical task in many real-world applications. Recent studies generally model graph using neural networks to capture implicit dependencies among users. However, existing construct way which cannot fully describe global of users due their narrow definition user relationship. Meanwhile, these methods are n...
