Underdetermined Blind Audio Source Separation Using Modal Decomposition

EURASIP Journal on Audio, Speech, and Music Processing, 2007
This paper introduces new algorithms for the blind separation of audio sources using modal decomposition. Indeed, audio signals and, in particular, musical signals can be well approximated by a sum of damped sinusoidal (modal) components.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Exploring the Potential of Unsupervised Image Synthesis for SAR-Optical Image Matching

IEEE Access, 2021
We consider SAR-optical image matching problems, where correspondences are acquired from a pair of SAR and optical images. Recent methods for such a problem typically simplify the SAR-optical image matching to the SAR-SAR or optical-optical image ...
