Abstract:
A method produces a monolithic electromagnetic component containing elements including a coil with turns and a base made from a ferrite. The method includes obtaining a precursor of the ferrite, depositing a first layer of the precursor in a mold, depositing the elements including the coil on the first layer, depositing a second layer of the precursor on the coil, and co-sintering the first layer, the second layer and the elements in the mold by pressure.
Abstract:
The present invention concerns a process for creating a Carbon-Carbon bond (C—C) or a Carbon-Heteroatom bond (C—HE) by reacting a compound carrying a leaving group with a nucleophilic compound carrying a carbon atom or a heteroatom (HE) that can substitute for the leaving group, creating a C—C or C—HE bond, wherein the reaction takes place in the presence of an effective quantity of a. a catalytic system comprising a ligand and at least a metal-based catalyst, such a metal catalyst being chosen among iron or copper compounds proviso that only a single metal is present.
Abstract:
A method for in vitro obtaining human retinal progenitors, includes the steps of (i) placing an adherent culture of human pluripotent stem cells in a pro-neural medium; and (ii) maintaining this culture in the pro-neural medium until the appearance of pigmented cells and/or of neuroepithelial-like structures. Additional steps can be performed to obtain RPE cells and/or precursors of the neural retina.

The invention concerns a method for encoding a video stream, an associated method for decoding a video stream, an associated encoder, an associated decoder and associated computer programs. The encoding method is directed to encoding a video stream comprising at least one video sequence, comprising, for the encoding of a square or rectangular block of a picture of a video sequence of the video stream, selecting a motion information predictor for the block from a list of candidate motion information predictors, and entropic encoding of an index representative of a position of the selected motion information predictor in the list.
Abstract:
An electronic temperature sensor for measuring the junction temperature of an electronic power switch (4) of a static converter (8) includes an injection source of a calibrated measurement current (20) and a differential voltage measurement amplifier (76; 276). The electronic temperature sensor includes a first series connection (26) element and a second series connection (28) connected respectively to the inlet terminals (78, 80) of the differential voltage amplifier (76; 276).

Abstract:
The method comprises the following steps: injecting (100) a sample into a capillary; transporting (110) the sample along the capillary in experimental conditions suited to generate a Taylor dispersion phenomenon; generating (120) a signal characteristic of the Taylor dispersion; processing (130) the signal in order to obtain the experimental Taylor signal Ŝ(t); and analysing (200) the experimental Taylor signal Ŝ(t), The analysis step consists of seeking an amplitude distribution P(G(c)) that allows the experimental Taylor signal Ŝ(t) to be broken down into a sum of Gaussian functions by implementing a constrained regularization algorithm consisting of minimising a cost function Hα including at least one constraint term associated with a constraint that must observe the amplitude distribution P(G(c)) , whereby the minimization is carried out on an interval of interest of the values of the parameter G(c) that is characteristic of the Gaussian amplitude function P(G(c)).
