摘要： Some variations provide a metal matrix nanocomposite composition comprising metal-containing microparticles and nanoparticles, wherein the nanoparticles are chemically and/or physically disposed on surfaces of the microparticles, and wherein the nanoparticles are consolidated in a three-dimensional architecture throughout the composition. The composition may serve as an ingot for producing a metal matrix nanocomposite. Other variations provide a functionally graded metal matrix nanocomposite comprising a metal-matrix phase and a reinforcement phase containing nanoparticles, wherein the nanocomposite contains a gradient in concentration of the nanoparticles. This nanocomposite may be or be converted into a master alloy. Other variations provide methods of making a metal matrix nanocomposite, methods of making a functionally graded metal matrix nanocomposite, and methods of making a master alloy metal matrix nanocomposite. The metal matrix nanocomposite may have a cast microstructure. The methods disclosed enable various loadings of nanoparticles in metal matrix nanocomposites with a wide variety of compositions.

摘要： A method and apparatus for enhancing the sensitivity of an oscillator circuit functioning, in use, to sense changes in the inductance of inductive elements and/or the capacitance of capacitive elements coupled to said oscillator circuit. The oscillator circuit is coupled to a nonlinear resonator for generating a comb of frequencies in response to a drive frequency generated by the oscillator circuit, the comb of frequencies having at least a portion of at least one tooth for which an absolute value of the first derivative of the drive frequency with respect to said comb frequency is less than 1.0, comparing an output of the nonlinear resonator with an output of a reference oscillator for detecting changes in the drive signal of the oscillator circuit as enhanced by the slope of the at least a portion of at least one tooth for which the absolute value of the first derivative of the drive frequency with respect to said comb frequency is less than 1.0.

摘要： A memory circuit configured to perform multiply-accumulate (MAC) operations for performance of an artificial neural network includes a series of synapse cells arranged in a cross-bar array. Each cell includes a memory transistor connected in series with a memristor. The memory circuit also includes input lines connected to the source terminal of the memory transistor in each cell, output lines connected to an output terminal of the memristor in each cell, and programming lines coupled to a gate terminal of the memory transistor in each cell. The memristor of each cell is configured to store a conductance value representative of a synaptic weight of a synapse connected to a neuron in the artificial neural network, and the memory transistor of each cell is configured to store a threshold voltage representative of a synaptic importance value of the synapse connected to the neuron in the artificial neural network.

摘要： A method of bonding a double-ended cable to a multi-tier substrate (such as a multi-tier printed circuit board) includes picking up the double-ended cable, and imaging alignment markers on a first head of the double-ended cable, a second substrate of the multi-tier substrate, a second head of the double-ended cable, and a first substrate of the multi-tier substrate. The method also includes aligning the alignment marker on the first head of the cable to the alignment marker on the second substrate of the multi-tier substrate, coupling the first head of the cable to the second substrate, and releasing the first head of the cable. The method further includes aligning the alignment marker on the second head of the cable to the alignment marker on the first substrate of the multi-tier substrate, coupling the second head of the cable to the first substrate, and releasing the second head of the cable.

摘要： Described is a system and method for accurate image and/or video scene classification. More specifically, described is a system that makes use of a specialized convolutional-neural network (hereafter CNN) based technique for the fusion of bottom-up whole-image features and top-down entity classification. When the two parallel and independent processing paths are fused, the system provides an accurate classification of the scene as depicted in the image or video.

摘要： Antimicrobial coatings that are transparent and not easily stained are disclosed. Some variations provide a transparent antimicrobial structure comprising: a discrete solid structural phase comprising a solid structural polymer with a glass-transition temperature from 25° C. to 300° C.; a continuous transport phase interspersed within the discrete solid structural phase, wherein the continuous transport phase comprises a solid transport material; and an antimicrobial agent contained within the continuous transport phase, wherein the antimicrobial agent is dissolved in a fluid and/or in a solid solution with the continuous transport phase. The discrete solid structural phase and the continuous transport phase are separated by an average phase-separation length selected from 100 nanometers to 500 microns. This invention resolves the trade-off between antifouling and fluorinated material content. This invention also resolves the trade-off between transport of absorbed molecules and transparency. The result is an improved antimicrobial structure that is both antifouling and transparent.
