摘要： A method for measuring pollution that includes providing a plurality of analyte sensors arranged in a grid over a sensing area, wherein the analyte sensors measure a pollutant, and positioning at least one current sensor in the sensing area. A pollution source is localized using a pollution source locator including a dispersion model and at least one hardware processor to interpolate a location of a pollution source from variations in current measured from the current sensors and measurements of pollutants from the analyte sensors.

摘要： A method of fabricating a symmetric element of a resistive processing unit (RPU) includes forming a substrate with a channel region connecting two doped regions, and forming a source above one of the two doped regions and a drain above the other of the two doped regions. A gate is formed above the channel region, and a bar ferroelectric is disposed above the channel region and below the gate.

摘要： A private key of a public-private key pair with a corresponding identity is written to an integrated circuit including a processor, a non-volatile memory, and a cryptographic engine coupled to the processor and the non-volatile memory. The private key is written to the non-volatile memory. The integrated circuit is implemented in complementary metal-oxide semiconductor 14 nm or smaller technology. The integrated circuit is permanently modified, subsequent to the writing, such that further writing to the non-volatile memory is disabled and such that the private key can be read only by the cryptographic engine and not off-chip. Corresponding integrated circuits and wafers are also disclosed.

摘要： A method is presented for incorporating a metal-ferroelectric-metal (MFM) structure in a cross-bar array in back end of the line (BEOL) processing. The method includes forming a first electrode, forming a ferroelectric layer in direct contact with the first electrode, forming a second electrode in direct contact with the ferroelectric layer, such that the first electrode and the ferroelectric layer are perpendicular to the second electrode to form the cross-bar array, and biasing the second electrode to adjust domain wall movement within the ferroelectric layer.

摘要： A sensor including a surface plasmon resonance detector with a reservoir for containing a liquid sample. The sensor further includes a sensing metallic film positioned within the reservoir so that at least a majority of a surface of the sensing metallic film is to be in contact with the liquid sample being housed within the reservoir. The sensory also includes a semiconductor device having a contact in electrical communication with the sensing metal containing film that is positioned within the reservoir. The semiconductor device measures the net charges of molecules within the liquid sample within a Debye length from the sensing metallic film.

摘要： Techniques for facilitating event driven gas sensing and source attribution are provided. In one example, a computer-implemented method comprises generating, by a device operatively coupled to a processor, a gas sensor signal indicative of sensing a gas based on the sensing the gas by one or more sensors. Additionally, the computer-implemented method can comprise converting, by the device, the gas sensor signal from an analog signal to a digital signal to identify one or more peak events based on the digital signal being determined to have satisfied a condition.

摘要： Atmospheric particle detectors having a hybrid measurement cavity and light baffle are provided. In one aspect, an atmospheric particle detector includes: an optical measurement cavity; a light baffle attached to the optical measurement cavity, wherein the light baffle is configured to i) permit unobstructed airflow into the optical measurement cavity and ii) block ambient light from entering the optical measurement cavity; a photodetector on a first side of the optical measurement cavity; a retro reflector on a second side of the optical measurement cavity opposite the photodetector, and a light source configured to produce a light beam that passes through the optical measurement cavity without illuminating the photodetector. A method for particle detection using the atmospheric particle detector is also provided.
