Abstract: A compensator compensates for the distortions of a power amplifier circuit. A power amplifier neural network (PAN) is trained to model the power amplifier circuit using pre-determined input and output signal pairs that characterize the power amplifier circuit. Then a compensator is trained to pre-distort a signal received by the PAN. The compensator uses a neural network trained to optimize a loss between a compensator input and a PAN output, and the loss is calculated according to a multi-objective loss function that includes one or more time-domain loss function and one or more frequency-domain loss functions. The trained compensator performs signal compensation to thereby output a pre-distorted signal to the power amplifier circuit.

Abstract: Disclosed are methods for direct, rapid and sensitive detection of plastic contaminants, such as microplastics (MPs) and nanoplastics (NPs), using flame ionization mass spectrometry (FI-MS) and flame-assisted atmospheric-pressure chemical ionization mass spectrometry (FAPCI-MS).

The method achieves analysis of solid samples in under 10 seconds.

Abstract: The disclosure generally describes methods, software, and systems for interaction performance analysis. Aggregated summary reports including aggregated event-data collected are received, from application programming interfaces, by the application programming interfaces, during events corresponding to interactions with user interfaces. The aggregated event-data is aggregated using a hierarchical structure corresponding to a data type.

Operations are determined using the denoised aggregated summary reports. An instruction to activate at least one of the operations using the denoised aggregated summary reports is provided, to an asset provider system.
