Adaptive filtering techniques for interferometric data preparation:   removal of long-term sinusoidal signals and oscillatory transients
  We propose an adaptive denoising scheme for poorly modeled non-Gaussian features in the gravitational wave interferometric data. Preliminary tests on real data show encouraging results.
