Abstract: Substrates may include a useful layer affixed to a support substrate. A surface of the useful layer located on a side of the useful layer opposite the support substrate may include a first region and a second region. The first region may have a first surface roughness, may be located proximate to a geometric center of the surface, and may occupy a majority of an area of the surface. The second region may have a second, higher surface roughness, may be located proximate to a periphery of the surface, and may occupy a minority of the area of the surface.

Abstract: A method and system for detecting and characterizing weak signals of risk exposure of a patient, a weak signal being representative of an incubation of a pathology, from patient data collected over a given time interval. The system includes a module for calculating a predictive risk signature, a module for detecting the presence of at least one weak risk exposure signal by comparing the calculated predictive risk signature to predetermined reference risk signatures, and in case of a positive detection, application of a module for determining a predictive reference signature associated with the calculated predictive risk signature and for characterizing the risk associated with the reference risk signature, including a module for displaying a previously determined and recorded threat scenario in association with the predictive reference signature.

Abstract: Method for learning synaptic weight values of a neural network, related data processing method, computer program, calculator and processing system
The invention relates to a method for training synaptic weight values of at least one layer of an artificial neural network.
The method is computer-implemented, and comprises training the weight values from training data, each weight value from said training being a quantized weight value belonging to a set of quantized values.
The set of quantized values consists of values encoded with a predefined number B of bits, and with a quantization step P between two successive quantized values that satisfies:




P
=

1

⌊



2
B

-
1

2

⌋






where └.┘ represents the integer part function; the quantized values also being included in a predefined interval chosen from the interval [−1−P; 1] and the interval [−1; 1].

Abstract: An artificial neuron for a neuromorphic chip comprises a synapse with resistive memory representative of a synaptic weight. The artificial neuron comprises a read circuit, an integration circuit and a logic circuit interposed between the read circuit and the integration circuit. The read circuit is configured to impose on the synapse a read voltage independent of the membrane voltage and to provide an analogue value representative of the synaptic weight. The logic circuit is configured to generate from the analogue value a pulse having a duration. The integration circuit comprises an accumulator of synaptic weights at the terminals of which a membrane voltage is established and a comparator configured to emit a postsynaptic pulse if a threshold is exceeded by the membrane voltage. Moreover, it comprises a source of current controlled by the pulse to inject a current into the accumulator of synaptic weights during this duration.

Abstract: An electromagnetic device for converting energy comprises: a ferromagnetic core of essentially planar shape and delimited by a peripheral contour; a primary winding and a secondary winding formed by primary turns and secondary turns, respectively. The device includes, arranged against the peripheral contour, a first block and a second block and a ferromagnetic material, and has a magnetic permeability lower than that of the ferromagnetic core. At least one primary turn and/or at least one secondary turn is formed around or passing through the first block and/or the second block to form, respectively, a first leakage inductance and/or a second leakage inductance.
