The present invention relates to solid salt forms of the 3-pyrrole substituted 2-indolinone compound 5-5-fluoro-2-oxo-1,2-dihydro-indol–ylidenemethyl-2,4-dimethyl-1H-pyrrole-3-carboxylic acid -amide. A request to edit a source document comprising text using a first markup language may be received. Feature vectors, including the mean heart rate of the photoplenthysmogram and its standard deviation, the very low frequency, low frequency, and high frequency components of heart rate variability, the frequency and mean amplitude of skin conductance responses, and the mean and maximum skin temperatures, are extracted from the detected biological signals. In another aspect, a method of forming a hookstrip screen assembly for use in a shaker. Another aspect of the present invention is an integrated system for depositing a copper layer onto a barrier layer for semiconductor device metallization.
