Cholesterol is a molecule, which plays essential structural role in eucaryotic cells; which includes 30 – 50 mol % of cholesterol. It increases the orientational order of membrane lipid chains and decreases membrane permeability while maintaining membrane fluidity. When added to the phospholipids in model membranes at concentrations higher than 30 mol % it(More)
The acquisition of hundreds of images of a scene, each at a different wavelength, is known as hyperspectral imaging. This high amount of data allows the extraction of much more information from hyperspectral images compared with conventional color images. The forward-looking imaging approach emerged from remote sensing, but is still not very widespread in(More)
The estimation of the time delay of arrival (TDOA) or the direction of arrival (DOA) has been an important research topic within the last few decades. In several applications, e.g., acoustic source localization or source separation, the estimation of the delay or the direction is a significant processing block. Most of the available algorithms estimate the(More)
