The removal of atmospheric components, a key factor that controls all subsequent image processing, is
usually dealt through statistical or physical models. However, noise components may not be comple...
SPECTRA OF MIXED PIXELS: DO THEY REPRESENT THE ACTUAL LAND COVER ON THE GROUND? - A CASE STUDY FOR A WET SAVANNA ECOSYSTEM IN UGANDA
Wet Savanna Ecosystem Wood-Grass Mixtures Mixed Pixels

a method for accurate determination of monoisotopic peaks in high-resolution mass spectra
monoisotopic high-resolution
2013/7/24
Determining the monoisotopic peak of a precursor is a first step in interpreting mass spectra, which is basic but non-trivial. The reason is that in the isolation window of a precursor, other peaks in...
