Abstract: A method for repairing a damaged aircraft fuselage outer skin part, the damaged skin part comprising a static pressure port around which is arranged a stopper fastened to a structure of the fuselage at which a pipe of the static pressure port opens, the method including removing the stopper from the static port, fitting a patch including an opening for housing the stopper, and re-fitting the stopper on an adjustable-thickness spacer. A repair assembly configured to apply the repair method is also provided. Advantageously, it is thus possible to recreate an aerodynamic profile in accordance with the requirements for taking static pressure of the aircraft, with a reduced down-time of the aircraft.

Abstract: Methods for fragmentation of large molecular ions, including proteins, nucleic acids, dendromers, and nanomaterials, compatible with several mass spectrometric techniques. The methods involve providing a gas-phase ion and allowing the gas phase ion to undergo collisions with metastable states of noble gases or nitrogen gas.

Abstract: A analog-to-digital converter includes: an analog signal input, a reference voltage source, a portion for the combined processing of the analog signal and reference voltage, and a coding portion for supplying a digital output signal which is a function of the results of this processing. The processing portion includes at least one level of processing operators suitable for carrying out a non-linear calculation from their inputs; the coding portion include one level of output operators, each having as many inputs as there are outputs in the last level of operators in the processing portion. The transfer functions of the processing operators and output operators are chosen so as to allow an optimum analog-to-digital conversion over a given range of input signals.
