The invention is based on the finding that cells that show phosphorylation of FGF-R substrate 2, in contrast to cells that lack such phosphorylation, allow a prediction that treatment with a modulator, especially an inhibitor, of Fibroblast Growth Factor-Receptor signaling will be successful in cells e. The process allows the winding of stators in which the pole horns largely cover the rotor external diameter of collector motors, leading to a higher motor power. unwound therefrom, said carriage providing a well-tuned process with maximum compactness of the turns.
