A Biophysical Approach to the Design of Networks of Communication Systems
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT Inspired by the growth dynamics of the protist Physarum polycephalum, we employ a formalism that describes adaptive, incompressible Hagen‐Poiseuille flows on channel networks to identify graphs connecting different nodes within Euclidean space. These graphs are either suboptimal or optimal relative to their length.

Velocity Spectrum Imaging Using Velocity Encoding Preparation Pulses
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose The goal of this article is to introduce a technique to measure the velocity distribution of water inside each voxel of an MR image. The method is based on the use of motion sensitizing gradients with changing first moment to encode velocity. As such, it is completely non‐invasive and requires no contrast injections.

Time‐Division Multiplexing for Parallel Transmission at Ultra‐High Field With Limited RF Channels
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Investigating time‐division multiplexing for parallel transmission in ultra high‐field imaging, striving for homogeneous whole brain excitation with a limited number of RF channels. Methods A fast RF switch was built to alternately route 8 transmit channels to each row of a double‐row 16‐element transmit coil array at a 9.4 T human MRI

Calibration‐Free GRAPE pTx Pulses for Homogeneous Spatial‐Selective Excitation at 7T
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Extend the universal pulse GRAPE formalism to pulses with a defined spectral response, and apply the concept to spatial selection. Methods We added Bloch simulations at several frequencies for each voxel to the pulse calculation to create universal spectrally‐selective GRAPE pulses.
