Shimming is an essential process for most NMR experiments, and time saving in this process is desired. Here we propose a fast 3D gradient shimming with a low resolution of only 2×2 pixels in the XY plane, and the number of pixels in the Z direction remains unchanged. The proposed pulse sequences employ the selective excitation and the convection compensation. Consequently, the fast 3D gradient ...

abstract the present article will discuss the issue of compensation in cases of expropriation and nationalization in the light of the iran-united states claims tribunal. it is a well recognized rule in international law that the property of alien cannot be taken without appropriate compensation. but, the standard of compensation for expropriated private property has been the subject of controv...

In this paper, we consider a mmWave massive multiple-input multiple-output (MIMO) communication system with one static base station (BS) serving fast-moving user, both equipped very large array. The transmitted signal arrives at the user through multiple paths, each different angle-of-arrival (AoA) and hence Doppler frequency offset (DFO), thus resulting in fast time-varying multipath fading MI...
