Abstract: A system may receive captured content identifying a first face of a user of a user device and media content identifying a second face of a person. The system may process the captured content and the media content, using a first machine learning model, to determine embeddings for the captured content and to identify landmarks in the media content. The system may combine the captured content with the media content, based on the landmarks and the embeddings, to generate combined content and to segment a combined face of the combined content, to replace the second face of the media content with the combined face, and to generate new media content that includes the combined face. The system may process the new media content, with a second machine learning model, to blend the combined face in the new media content and to generate final media content.

Abstract: A microhotplate comprising a membrane suspended over a substrate by a plurality of tethers connected between the substrate and the membrane. The membrane comprises a resistive heater comprising an electrically conductive material having a varying width from a peripheral portion of the membrane to a center of the membrane. The electrically conductive material comprises a first portion spiraling in a first direction and a second portion spiraling in a second direction and in electrical communication with the first portion at the center of the membrane. The microhotplate further comprises a first electrically conductive trace extending over a first tether and in electrical contact with a bond pad on the substrate and the first portion and a second electrically conductive trace extending over another tether and in electrical contact with another bond pad on the substrate and the second portion. Related chemical sensors and related methods of detecting at least one analyte are also disclosed.

Abstract: A method of controlling a rate of introduction of a NOx reducing substance or precursor to a catalyst component. The method comprises obtaining the amount of NOx entering the catalyst component, modeling the amount of NOx reducing substance or precursor in the catalyst component and controlling the rate of introduction of the NOx reducing substance or precursor to reduce NOx.
