The coupled transmission line includes a first transmission line, a second transmission line, and a switch configured to couple the first and second transmission lines during a first mode of operation and to decouple the first and second transmission lines during a second mode of operation. The radio frequency couple can be used in a front end module of a communications device, such as a mobile phone.

Abstract: Disclosed in some examples are methods, systems, and machine-readable mediums which determine jitter buffer delay by inputting jitter buffer and currently observed network status information to a machine learned model that is trained using a reinforcement learning (RL) method. The model maps these inputs to an action to compress, stretch, or hold the jitter buffer delay, which is used by a recipient computing device to optimize the jitter buffer delay. The model may be trained using a simulator that uses network traces of past real streaming sessions (e.g., communication sessions) of users. By training the model through reinforcement learning, the model learns to make better decisions through reinforcement in the form of reward signals that reflect the performance of each decision.

Abstract: Described herein are systems and techniques for monitoring substances that are injected into an Earth formation whether that be CO2 from a carbon capture and storage (CCS) process, or water or steam injected for an enhanced oil recovery (EOR) process. Components located on an outside of a wellbore casing may be electrically isolated from components located on the inside of the wellbore casing. Data and/or power may be transferred through the wellbore casing wirelessly in order to increase the reliability of a data collection system because the need for wires to be placed on the outside surface of a wellbore casing is eliminated. The components located on the outside of the casing may receive electromagnetic (EM) or transmit EM fields as part of a system that collects data about substances that are injected into Earth formations during a CCS or EOR process.

Abstract: Methods and systems described herein may implement operations for identification of computing issues on computing platforms using social media comments and other available data in a variety of environments. An online transaction processor may provide operations for electronic transaction processing and/or other online computing services. The online transaction processor may monitor social media posts in order to determine if context and sentiments from such posts may indicate that there is a potential issue or complaint by users with computing services provided by the online service provider. This may be done by processing the posts using a machine learning engine for sentiment analysis and correlating sentiments with corresponding computing signals occurring with computing platforms of the service provider. Thereafter, computing anomalies may be detected and output notifications may be provided to users based on the corresponding computing anomalies.

Abstract: An entry of a last level cache shadow tag array to track pending last level cache misses to private data in a previous level cache (e.g., an L2 cache), that also are misses to an exclusive last level cache (e.g., an L3 cache) and to the last level cache shadow tag array. Accordingly, last level cache miss status holding registers need not be expended to track cache misses to private data that are already being tracked by a previous level cache miss status holding register. Additionally or alternatively, up to a threshold number of last level cache pending misses to the same shared data from different processor cores are tracked in the last level cache shadow tag array, and any additional last level cache pending misses are tracked in a last level cache miss status holding register.

Abstract: Systems and methods for transforming data for a batch-based legacy software program into data suitable for processing by a streaming-based new software program. In some aspects, the system generates an information stream for multiple threads from batch information received from the legacy software program.

If there is a mismatch between outputs of the legacy and new software programs for at least one thread, the system adjusts a data model of the new software program to address the mismatch and generates an updated information stream for processing by the new software program.

Abstract: Innovations in phase quantization during speech encoding and phase reconstruction during speech decoding are described. For example, to encode a set of phase values, a speech encoder omits higher-frequency phase values and/or represents at least some of the phase values as a weighted sum of basis functions. Or, as another example, to decode a set of phase values, a speech decoder reconstructs at least some of the phase values using a weighted sum of basis functions and/or reconstructs lower-frequency phase values then uses at least some of the lower-frequency phase values to synthesize higher-frequency phase values. In many cases, the innovations improve the performance of a speech codec in low bitrate scenarios, even when encoded data is delivered over a network that suffers from insufficient bandwidth or transmission quality problems.
