Abstract: A method for manufacturing an acoustic device includes providing a substrate, providing a bottom electrode over the substrate, providing a sacrificial layer on the bottom electrode, patterning the bottom electrode and the sacrificial layer, polishing the sacrificial layer such that a portion of the sacrificial layer remains on the bottom electrode, and removing the remaining portion of the sacrificial layer via a cleaning process such that a surface roughness of the bottom electrode is maintained.

Abstract: Systems and methods are provided that train a machine-learned language encoding model through the use of a contrastive learning task. In particular, the present disclosure describes a contrastive learning task where the encoder learns to distinguish input tokens from plausible alternatives. In some implementations, on each training example the proposed method masks out some subset (e.g., 15%) of the original input tokens, replaces the masked tokens with samples from a “generator” (e.g., which may be a small masked language model), and then trains the encoder to predict whether each token comes from the original data or is a replacement produced by the generator.

Abstract: The rate limiter circuits in the packet processing chip of a NIC are a limited hardware resource that may limit the number of workloads that can be run on a server. Some such chips include an egress packet processing pipeline circuit and a second packet processing pipeline circuit that prepares work for the egress pipeline circuit. Some of the stages of the second pipeline circuit can be configured as a first limiter and a second limiter that implement aspects of different rate limiters such as IOPS limiters, bandwidth limiters, etc. Another pipeline stage can use the outputs of the different rate limiters to make a limiting decision that is written into one of the rate limiter circuits. The second pipeline circuit is thereby implementing virtualized rate limiters where one of the rate limiter circuits performs the rate limiting for the virtualized rate limiters.
