A method for magnetic resonance (MR) imaging , comprising:operating an MR data acquisition scanner in order to acquire a time series of raw MR data that represents a plurality of spatially-resolved neurophysical events in the brain of a subject;in a computer, reconstructing image data from said raw MR data depicting the brain with said spatially-resolved neurophysical events therein;in said computer, performing an independent component analysis (ICA) in order to identify a plurality of candidate correlation patterns among said plurality of neurophysical events, said plurality of candidate correlation patterns comprising actual correlation patterns of said plurality of neurophysical events and false patterns;in said computer, determining a section of the brain of the subject in the reconstructed image data;in said computer, for each correlation pattern in said plurality of candidate correlation patterns, determining a corresponding value of a predetermined metric that indicates an intensity of the respective candidate correlation pattern in the determined section of the brain;in said computer, selecting at least one candidate correlation pattern from said plurality of candidate correlation patterns dependent on the value of the predetermined metric thereof; andpresenting the at least one selected candidate correlation pattern at a display screen in communication with ...

PLATING BATH COMPOSITION AND METHOD FOR ELECTROLESS PLATING OF PALLADIUM

The invention relates to an aqueous plating bath composition and a method for depositing a palladium layer by electroless plating onto a substrate. The aqueous plating bath composition according to the invention comprises a source for palladium ions, a reducing agent for palladium ions and a cyanide group containing aromatic compound. The aqueous plating bath composition according to the invention has an improved stability against undesired decomposition due to the cyanide group containing aromatic compounds while keeping the deposition rate for palladium at the desired satisfying value. The aqueous plating bath composition has also a prolonged life time. The cyanide group containing aromatic compounds of the invention allow for adjusting the deposition rate to a satisfying range over the bath life time and for electrolessly depositing palladium layers at lower temperatures. 2.
