  • Patent number: 11302856
    Abstract: The present invention relates to an inductive dipole element for a superconducting microwave quantum circuit. The dipole element comprises a DC-SQUID formed by a pair of Josephson junctions shunted by an inductance, wherein the Josephson junctions have equal energy, and the Josephson junctions and the inductance are arranged such that each of the junctions forms a loop with the inductance. The two loops are asymmetrically threaded with external magnetic DC fluxes ?ext1 and ?ext2, respectively, such that ?ext1=? and ?ext2=0, wherein parametric pumping is enabled by modulating the total flux ??=?ext,1+?ext,2 threading the dipole element, thereby allowing even-wave mixing between modes that participate in the dipole element with no Kerr-like interactions.

  • Publication number: 20200386695
    Abstract: A method for controlling the crystallographic orientation of at least one grain of a turbo engine part. The method includes emitting a beam of electromagnetic radiation through an elementary volume of the part and record diffraction information on the electromagnetic radiation passing through the part. This step is repeated on a given area of the part. The method further includes determining the crystal spatial orientation of each of said elementary volumes and deducting the presence of at least one first crystallographic grain for which the elementary volumes are oriented according to the same crystallographic orientation. The method further includes calculating the angular difference between the crystal spatial orientation of said first grain and a predetermined direction taken from the part and comparing it to a first predetermined threshold value and determining a state of use of the part.

  • Patent number: 10301602
    Abstract: Production of virus occlusion bodies that occlude virions comprising genomes of different species of baculoviruses that can be used to combat insect pests. A method is presented for the production of occlusion derived virions (ODVs) that simultaneously comprise genomes of different baculovirus species, occluded in a viral occlusion body (OB) with the structural and morphological features characteristic of baculoviruses. Mixed genome ODVs and OBs can be produced by co-infecting insect cells or insect hosts using two or more different baculoviruses species. Co-infection may be achieved by simultaneous inoculation of the different baculoviruses or with a time interval between inoculations, which results in different proportions of each species' genomes in the ODVs and OBs that are produced. The produced OBs can be used either directly for preparing an insecticide, or to infect susceptible insects to produce larger quantities of mixed genome ODVs and OBs, also useful for combating pest insects.
