Abstract: To simultaneously acquire spectroscopic signals from two MRS voxels using a multi‐banded 2 spin‐echo, full‐intensity acquired localized (2SPECIAL) sequence, and to decompose the signal to their respective regions by a novel voxel‐GRAPPA (vGRAPPA) decomposition approach…

Abstract: The time-variant quantum communication channel affected by uncontrollable environmental factors induces an unrepeatable evolution of Bell states, which calls for a universal method of evolution reconstruction. The novel Fourier-based method proposed recently is extended and…

Abstract: The Fourier-based gradient field integration method can efficiently reconstruct transparent surfaces from the measured gradient data in the Shape-from-polarization method. However, for the differentiation operator having large truncation errors and lacking constraints on adjacent heights,…

Abstract: A fundamental challenge in learning is the presence of nonlinear redundancies and dependencies in the data. To address this, we propose a Fourier-based approach to characterize feature redundancies, in unsupervised learning, and feature-label dependencies, in…

Abstract: Abstract. Wavefront sensors (WFSs) encode phase information of an incoming wavefront into an intensity pattern that can be measured on a camera. Several kinds of WFSs are used in astronomical adaptive optics. Among them, Fourier-based…
