    摘要： A method for preparing a nanoporous silica sol-gel matrix containing at least one amine reactant selected from hydroxylamine, methylhydroxylamine, tertbutylhydroxylamine, methoxyamine, tetraethylenepentamine, dicarboxylic acid dihydrazides, particularly adipic acid dihydrazide, and the salts thereof, said method including the following steps: a) synthesising a gel from tetramethoxysilane or from a mixture of tetramethoxysilane and another organosilicon precursor selected from among phenyltrimethoxysilane, phenyltriethoxysilane, a fluoroalkyltrimethoxysilane, a fluoroalkyltriethoxysilane, a chloroalkylmethoxysilane, a chloroalkylethoxysilane, an alkyltrimethoxysilane, an alkyltriethoxysilane, an aminopropyltriethoxysilane and the mixtures thereof, the synthesis being performed in an aqueous medium at a temperature ranging from 10 to 70° C. in the presence of at least one amine reactant selected from among hydroxylamine, methylhydroxylamine, tertbutylhydroxylamine, methoxyamine, dicarboxylic acid dihydrazides, particularly adipic acid dihydrazide, and the salts thereof; b) drying the gel obtained during step a) so as to obtain a sol-gel matrix containing at least one amine reactant.

    摘要： Disclosed is a method for characterising an object, comprising: emission of ultrasonic waves that enter an object by passing through an external interface, then reflect off an internal interface, then exit the object by passing through the external interface again, the ultrasonic waves comprising first waves having a mode that varies according to a first variation during their propagation in the object, and second waves having a mode that varies according to a second variation during their propagation in the object; reception of echo signals comprising first signals representing echoes of the first waves, and second signals representing echoes of the second waves, construction of a plurality of images showing the object, the plurality of images being constructed from the echo signals, under the assumption that two characteristics of the object are equal to two candidate values, and comprising a first image constructed from the first signals, and a second constructed from the second signals; construction of a composite image from the plurality of images; calculation of a focus metric in the composite image and, depending on the metric, selection or not of the two candidate values as values of the two characteristics. These characteristics can be used, in particular, to estimate a thickness of the object between the two interfaces.

    摘要： A medical analysis device with cellular impedance signal processing comprises a memory (4) arranged to receive pulse data sets, each pulse data set comprising impedance value data that are associated each time with a time marker, these data together representing a curve of cellular impedance values that are measured as a cell passes through a polarised opening. This device further comprises a classifier (6) comprising a convolutional neural network receiving the pulse data sets as input and is provided with at least one convolutional layer, which convolutional layer has a depth greater than or equal to 3, and at least two fully connected layers, in addition to an output layer rendering a cell classification from which a pulse data set is derived.
