Abstract: A method for sealing cavities using membranes, the method including a) forming cavities arranged in a matrix, of a depth p, a characteristic dimension a, and spaced apart by a spacing b; and b) forming membranes, sealing the cavities, by transferring a sealing film. The method further includes a step a1), executed before step b), of forming a first contour on the front face and/or on the sealing face, the first contour comprising a first trench having a width L and a first depth p1, the formation of the first contour being executed such that after step b) the cavities are circumscribed by the first contour, said first contour being at a distance G from the cavities between one-fifth of b and five b.

Abstract: A nuclear reactor incorporates a fully passive decay heat removal system with a modular cold source. The decay heat removal system is configured to remove heat passively, via the outside of a primary vessel included in the nuclear reactor. The cold source has a plurality of modules grouped together in assemblies. Each module is filled with a phase change material. Each module is cooled by a monotube heat exchanger. The decay heat removal system includes a hot collector and a cold collector to ensure the distribution of a heat transfer fluid in the plurality of monotube heat exchangers.

Abstract: A Bayesian neural network including an input layer, and, an output layer, and, possibly, one or more hidden layer(s). Each neuron of a layer is connected at its input with a plurality of synapses, the synapses of the plurality being implemented as a RRAM array constituted of cells, each column of the array being associated with a synapse and each row of the array being associated with an instance of the set of synaptic coefficients, the cells of a row of the RRAM being programmed during a SET operation with respective programming current intensities, the programming intensity of a cell being derived from the median value of a Gaussian component obtained by GMM decomposition into Gaussian components of the marginal posterior probability of the corresponding synaptic coefficient, once the BNN model has been trained on a training dataset.

Abstract: A surface treatment method includes providing a substrate with a surface having areas of selective epitaxy of a first material and masses of matter of the first material; forming a protection layer, produced in a second material, on the surface of the substrate; and forming a flattening layer on the protection layer. Areas of the flattening layer facing the masses of matter and top areas of the protection layer are removed so as to expose the masses of matter. Lateral areas of the protection layer are etched by a selective wet chemical etching. The flattening layer is removed; the masses of matter are etched, the protection layer forming an etch mask; and protection layer is removed.
