Surrogates with random Fourier Phases
Christoph Raeth, Roberto A. Monetti
The method of surrogates is widely used in the field of nonlinear data analysis for testing for weak nonlinearities. The two most commonly used algorithms for generating surrogates…

Detecting non-linearities in data sets. Characterization of Fourier phase maps using the Weighted Scaling Indices
Roberto A. Monetti, Wolfram Bunk, Ferdinand Jamitzky +2
We present a methodology for detecting non-linearities in data sets based on the characterization of the structural features of the Fourier phase maps. A Fourier phase map is a 2D…

Observing the Evolution of the Universe
James Aguirre, Alexandre Amblard, Amjad Ashoorioon +172
How did the universe evolve? The fine angular scale (l>1000) temperature and polarization anisotropies in the CMB are a Rosetta stone for understanding the evolution of the univers…
