Abstract: A method for manufacturing a superconducting LC-type resonator of the type including at least one high-resistivity substrate on which are printed an inductive meander, a first so-called lower electrode and a second so-called upper electrode arranged opposite the first so as to form together a capacitor connected in parallel with the inductive meander, as well as inductive coupling means dedicated to the resonator, in which a sacrificial aluminium layer is deposited between the first and second electrodes. Also disclosed is the superconducting LC-type resonator thus obtained and the use of such a resonator for detecting the noise of a millimetre photon.

Abstract: A method for the preparation of an electrode comprising a substrate made of an aluminium based material, vertically aligned carbon nanotubes and an electrically conductive polymer matrix, the method comprising the following successive steps: (a) synthesising, on a substrate made of an aluminium based material, a carpet of vertically aligned carbon nanotubes according to the technique of CVD (Chemical Vapour Deposition) at a temperature less than or equal to 650° C.; (b) electrochemically depositing the polymer matrix on the carbon nanotubes from an electrolyte solution including at least one precursor monomer of the matrix, at least one ionic liquid and at least one protic or aprotic solvent. Further disclosed is the prepared electrode and a device for storing and returning electricity such as a supercapacitor comprising the electrode.

Abstract: The present invention relates to a method for producing a support at least micrometric in size, photocatalytically active and at least in the visible range, containing nanocrystals each composed of from 80 to 100 mol % of TiO2 and from 0 to 20 mol % of at least one other metal or semi-metallic oxide, comprising the following steps, from an acidic aqueous reaction medium, at a heating temperature of between 20 and 60° C.

Abstract: The invention relates to a method for producing an image numerical classifier, to automatically determine the visualization quality of endoscopy videocapsule images of segments of the digestive tract, comprising a step of acquiring a video in the digestive tract by a videocapsule; a step of extracting images from the video; a so-called “ground truth” step of clinically evaluating the visualization quality of the images based on medical criteria, a step of selecting an initial set of “adequate” visualization images and “inadequate” visualization images, a step of calculating at least one numerical parameter relating to at least one of the medical criteria, a statistical machine learning step to produce the numerical classifier.

Abstract: A polar code decoding method in which a first decoding attempt by successive cancellation is performed and in the case where the decoded frame is erroneous, an ordered list of bit positions to be tested in the frame is generated, the order relation being given by a metric of first error, the value of this metric depending on the reliability of the decision about the bit as well as on the reliability of the decisions about the bits preceding it in the frame. For each of the positions of the list, an inversion of the bit and a decoding of the subsequent bits are undertaken, doing so as long as the list has not been exhausted or the frame has not been decoded without error. In case of failure, a new decoding attempt based on a double-inversion of bits can be envisaged.

Abstract: The present invention concerns a method for preparing a composite material comprising electrically conductive or semiconductive nano-objects of elongate shape and an electrically conductive polymer matrix, said method comprising a step consisting in electrochemically deposing said matrix on said nano-objects using a pulsed galvanostatic technique. The present invention also concerns the composite material thus obtained and uses thereof.

Abstract: An in-between layer partial syndrome stopping (IBL-PS) criterion for a layered LDPC decoder. The IBL-PS syndrome is obtained by applying the parity checks (Hr,r+1) of a couple of a first layer (r) and a second layer (r+1) on the variables after the first layer has been processed and before the second layer is processed by the decoder, the decoding being stopped if said in-between layer syndrome (sr,r+1) is satisfied for at least a couple of consecutive layers.
