Abstract: Data base performance is improved using write-behind optimization of covering cache. Non-volatile memory data cache includes a full copy of stored data file(s). Data cache and storage writes, checkpoints, and recovery may be decoupled (e.g., with separate writes, checkpoints and recoveries). A covering data cache supports improved performance by supporting database operation during storage delays or outages and/or by supporting reduced I/O operations using aggregate writes of contiguous data pages (e.g., clean and dirty pages) to stored data file(s). Aggregate writes reduce data file fragmentation and reduce the cost of snapshots. Performing write-behind operations in a background process with optimistic concurrency control may support improved database performance, for example, by not interfering with write operations to data cache. Data cache may store (e.g., in metadata) data cache checkpoint information and storage checkpoint information. A stored data file may store storage checkpoint information (e.g.

Abstract: An analytics system receives, from a client computing device, a request to generate a presentation. The analytics system accesses one or more feedback datasets of feedback data. The feedback data comprises unstructured data available from multiple data stores. The analytics system generates, for each feedback dataset, a respective feedback text and a respective sentiment score indicating a degree of negativity associated with the respective feedback text. For a combination of a plurality of generated feedback texts, the analytics system selects a set of themes based at least on a plurality of generated sentiment scores. Each sentiment score of the plurality of generated sentiment scores is associated with one of the plurality of generated feedback texts. The analytics system generates a presentation file that indicates the set of themes. The analytics system causes the presentation file to be transmitted to the client computing device.

Abstract: Techniques are disclosed for monitoring a patient for the occurrence of cardiac arrhythmias. A computing system obtains a cardiac electrogram (EGM) strip for a current patient. Additionally, the computing system may apply a first cardiac rhythm classifier (CRC) with a segment of the cardiac EGM strip as input. The first CRC is trained on training cardiac EGM strips from a first population. The first CRC generates first data regarding an aspect of a cardiac rhythm of the current patient. The computing system may also apply a second CRC with the segment of the cardiac EGM strip as input. The second CRC is trained on training cardiac EGM strips from a smaller, second population. The second CRC generates second data regarding the aspect of the cardiac rhythm of the current patient. The computing system may generate output data based on the first and/or second data.

Abstract: In some examples, an individually-pruned neural network can estimate blood pressure from a seismocardiogram (SCG). In some examples, a baseline model can be constructed by training the model with SCG data and blood pressure measurement from a plurality of subjects. One or more filters (e.g., the filters in the top layer of the network) can be ranked by separability, which can be used to prune the model for each unseen user that uses the model thereafter, for example. In some examples, individuals can use individually-pruned models to calculate blood pressure using SCG data without corresponding blood pressure measurements.

Abstract: A network node stores connection data required for remote devices to connect with it and to share content data with it. The network node shares the connection data with other network nodes that are capable of communicating with the remote device and retrieves connection data for a remote device from another network node if the connection data is not stored in the first node. The network node also communicates with a remote server that is communication with a trusted vault via a private network to retrieve the connection data if it is not present in one of the other network nodes. The network node securely communicates content data received from the remote devices to a remote data store.

Abstract: A user equipment (UE) employing different radio access technologies (RATs) concurrently provides the UE the opportunity to connect with different RAT-based base stations and concurrently transmit data thereto. A power-sharing control mechanism provides for sharing and allocating transmit power to multiple active RATs at the UE based on a priority designation of the data type associated with transmissions scheduled for each of the multiple active RATs. The power-sharing control mechanism provides efficient transmit power sharing between multiple transmit active RATs such that allocation of power to one RAT does not adversely affect the performance or coverage of the remaining RATs.

The network device also determines that no identifier from the pool of identifiers has been allocated for the packet flow and determines an identifier available to allocate for the packet flow from the pool of identifiers. The network device performs a NAT operation on the packet based on the identifier.

Abstract: A process circularity optimization system improves the circularity of industrial processes via a non-linear analysis of process attributes. A process input provides one or more target attributes to be optimized along with an objective function for improving the circularity of a manufacturing process.
