First distributed performance-portable NUFFT scales to 1024 GPUs on heterogeneous systems and supports large particle-in-Fourier plasma simulations.
DMK extended to rectangular cuboids with arbitrary periodicity via localized octree evaluations on cubical tilings and Fourier-space root-level summation with truncated kernels for reduced periodicity.
Derives an explicit reconstruction formula for the contrast in the 2D acoustic inverse Born scattering problem by decoupling the linear system into independent triangular subsystems using Zernike decompositions solved via forward substitution.
Defines differentiable weak distance on SE(3) for surface measures via Sobolev norms and shows local optimization with trust-region methods and NUFFT gradients.
