Abstract: A differential amplifier having a first and second output terminals and receiving an input signal at an input terminal. The amplifier comprises a first amplifier having a first input connected to the input terminal, a second input and a first output connected together to the first output terminal, and a second output connected to the second output terminal, the first amplifier reproducing the input signal on the first output. The amplifier comprises a second amplifier having a first input receiving a reference signal and a second input connected to the output terminals by resistive elements and controlling the provision by the first amplifier on the second output of a signal such that the signals received at the first and second inputs of the second amplifier are equal.

Abstract: The present invention features formulations of indolinones. The formulation is suitable for parenteral or oral administration, wherein the formulation comprises an indolinone, and a pharmaceutically acceptable carrier therefor. The formulations and the compounds themselves are useful for the treatment of protein kinase related disorders.

Abstract: A railway vehicle having a variable trim body, comprising two bogies with respective swinging transverse members pivotally connected to the body, and a control system for controlling roll of the body about its longitudinal axis, by use of linear actuators interposed between the swinging transverse members and the opposite sides of the body and operated through a regulation electronic unit connected to a first transducer device detecting the non-compensated centrifugal acceleration acting on the body, and to a second transducer device comprising at least two angular transducers for detecting the momentary relative angle between each swinging transverse member and the body.
