Abstract: A method and system for acquiring a series of medical images includes receiving medical imaging data corresponding to photons emitted from a subject having received a dose of a radiotracer. Determining, from the medical imaging data, coincidence events including photon coincidence events involving two photons and photon coincidence events involving more than two photons. The photon coincidence events involving two photons and photon coincidence events involving more than two photons are processed and use to reconstruct a series of medical images of the subject.

Abstract: Procedure for obtaining a marker of objects to be identified, comprising at least one polymorphic DNA fragment and preferably a plurality of polymorphic DNA fragments, such as microsatellite or single base polymorphism, modified in their three-dimensional structure, adsorbed to metallic nanoparticles and micro encapsulated, which are active to Raman radiation. Said marker is also protected; as well as the marker detection method; the method to instantly authenticate marked objects with the said marker; the method to verify the marked objects with the said marker and the method for incorporating the said marker to the desired object to be identified.

Abstract: An NMR method is presented having enhanced sensitivity on a compound comprising hyperpolarizable nuclei, in particular applying enhanced PHIP. Polarization is thereby transferred from a prepared fluid, which is enriched with symmetric molecules of a particular spin state (e.g. para-hydrogen enriched), directly to the hyperpolarizable nuclei of a compound, without altering the chemical identity of the compound in this process. Spin transfer is achieved using a template having sites of ordered environment, and the fluid and the compound are brought together in the presence of the template. Polarization transfer to the hyperpolarizable nuclei of the compound is thereby easier to perform and can be applied to a broader scope of compounds.

Abstract: In order to give the current the quality of low sensitivity to temperature, a first MOS transistor and a second MOS transistor supplied by a current mirror have their sources connected to the ground, with the drain and the gate of the first transistor being connected to the gate of the second transistor by means of a resistor. The quotient of the dimensional ratios of the transistors is equal to the coefficient of the current mirror and the transistors are doped so that the threshold of the second transistor is greater than that of the first one. Application notably to ramp generators for the programming of EEPROM cells.
