Adaptive versus non-adaptive responses to drought in a non-native riparian tree / shrub, Tamarix spp
S. E. Bush,Jessica S. Guo,Donna Dehn,Kevin C. Grady,Julia B. Hull,Emily Johnson,Dan F. Koepke,Randall W. Long,Daniel Potts,Kevin R. Hultine +9 more
TL;DR: Results indicate that the high degree of reported Tamarix hybridization since its introduction to North America has largely produced a swarm of “generalist” genotypes in terms of drought sensitivity, which may result in someTamarix populations becoming maladapted sooner to reductions in available water than others in the western US.
Proceedings ArticleDOI
Fast Poisson solvers on nonequispaced grids: Multigrid and Fourier methods compared
Gisela Poeplau,Daniel Potts +1 more
TL;DR: Two Poisson solvers for data on nonequispaced mesh points are compared and a new meshless Fourier method based on NFFT is constructed in R3, compared to the well-established multigrid method working onNonequidistant meshes.
Journal ArticleDOI
On the reconstruction of functions from values at subsampled quadrature points
TL;DR: The subsampling procedure consists of a computationally inexpensive random step followed by a deterministic procedure to further reduce the number of points while keeping its information, and regains the optimal rate since many of the lattice points are not needed.

Learning high-dimensional additive models on the torus.
Daniel Potts,Michael Schmischke +1 more
TL;DR: The integral projection operator that leads to the classical ANOVA decomposition is used and an approximation method based on the truncated decomposition with regard to a superposition dimension $d_s$ is presented.

Uniform error estimates for nonequispaced fast Fourier transforms
Daniel Potts,Manfred Tasche +1 more
TL;DR: In this paper, the error behavior of the nonequispaced fast Fourier transform (NFFT) is studied and an approximate algorithm is proposed based on the convenient choice of a compactly supported window function.
