High Angular Resolution Diffusion Imaging (HARDI) improved many neurosurgical areas due to its ability to represent complex intra-voxel structures, but is limited for clinical use mainly due to long acquisition times, but also due to noise. To transcend these limits, our work addresses these problems by combining a state-of-the-art multi diffusion tensor model enhanced with spherical ridgelets....

The Fisher-matrix formalism is used routinely in the literature on gravitational-wave detection to characterize the parameter-estimation performance of gravitational-wave measurements, given parametrized models of the waveforms, and assuming detector noise of known colored Gaussian distribution. Unfortunately, the Fisher matrix can be a poor predictor of the amount of information obtained from ...
