Approximately achieving Gaussian relay network capacity with lattice codes
Abstract--Recently, it has been shown that a quantize-mapand-forward scheme approximately achieves (within a constant number of bits) the Gaussian relay network capacity for arbitr...

MR Image Reconstruction from Pseudo-Hex Lattice Sampling Patterns Using Separable FFT
Abstract— Common MRI sampling patterns in kspace, such as spiral trajectories, have nonuniform density and do not lie on a rectangular grid. We propose mapping the sampled data t...

Three-dimensional Random Voronoi Tessellations: From Cubic Crystal Lattices to Poisson Point Processes
We perturb the simple cubic (SC), body-centered cubic (BCC), and face-centered cubic (FCC) structures with a spatial Gaussian noise whose adimensional strength is controlled by th...
