Abstract: A memory sub-system configured to encode data using an error correcting code and an erasure code for storing data into memory cells and to decode data retrieved from the memory cells. For example, the data units of a predetermined size are separately encoded using the error correcting code (e.g., a low-density parity-check (LDPC) code) to generate parity data of a first layer. Symbols within the data units are cross encoded using the erasure code. Parity symbols of a second layer are calculated according to the erasure code. A collection of parity symbols having a total size equal to the predetermined size can be further encoded using the error correcting code to generate parity data for the parity symbols.

Abstract: A memory log retrieval and provisioning system includes a server device that is coupled to a support system via a network. The server device includes a memory device having at least one memory log. A memory log retrieval and provisioning subsystem is coupled to the memory device, and determines that a memory log retrieval event has occurred in the server device. In response to determining that the memory log retrieval event has occurred, the memory log retrieval and provisioning subsystem automatically retrieves the at least one memory log from the memory device without receiving user instructions subsequent to detecting the memory log retrieval event. The memory log retrieval and provisioning subsystem then automatically transmits the at least one memory log through the network to the support system without receiving user instructions subsequent to automatically retrieving the at least one memory log.

Abstract: Techniques for dynamic contact ingestion are described. A system may interpret a voice command received from a first device based on contact data or other information associated with a second device connected to the first device. For example, when a data connection is made between the first device and the second device, the first device may receive the contact data and send the contact data to a remote system. The remote system may temporarily associate the contact data with the first device, enabling the remote system to interpret a voice command received from the first device using the contact data. The remote system may use the contact data to perform disambiguation, enabling the remote system to initiate outbound calls, announce inbound calls, and/or the like. When the second device is disconnected from the first device, the remote system may remove the association between the contact data and the first device.

Abstract: In some examples, continuous learning-based application related trade-off resolution and implementation may include generating, based on a plurality of historical tradeoff instances, an application feature matrix. Further, association rules for historical tradeoff instances for which decisions are not known, and a decision tree for historical tradeoff instances for which decisions are known may be generated. Decision rules may be induced, and default rules may be applied to a cold start scenario. The decision rules and the default rules may be refined to generate refined rules, and a confidence level may be determined for the refined rules. The refined rules may be prioritized based on the confidence level and applied to a new tradeoff instance to generate a resolution associated with the new tradeoff instance. The resolution may be implemented with respect to the new tradeoff instance.

Abstract: Introduced here are computer programs and computer-implemented techniques for detecting instances of external fraud by monitoring digital activities that are performed with accounts associated with an enterprise. A threat detection platform may determine the likelihood that an incoming email is indicative of external fraud based on the context and content of the incoming email. For example, to understand the risk posed by an incoming email, the threat detection platform may seek to determine not only whether the sender normally communicates with the recipient, but also whether the topic is one normally discussed by the sender and recipient. In this way, the threat detection platform can establish whether the incoming email deviates from past emails exchanged between the sender and recipient.

Abstract: Instructions stored on a computer-readable medium include, in response to receiving a new message for transmission, generating a candidate message by attempting recovery of a previous message from the new message and recovery bits of the previous message. The instructions include, in response to an indicator indicating that the attempted recovery was successful, computing a delta between the new message and the candidate message and generating a delivery message based on the computed delta. The instructions include, in response to the indicator indicating that the attempted recovery was unsuccessful, generating the delivery message based on the new message exclusive of the computed delta. The instructions include calculating new recovery bits from the new message. The instructions include storing the new recovery bits as the recovery bits of the previous message. The instructions include transmitting the delivery message to a destination over a communications channel.

A single-catheter system with integrated multiple lumens may have a first lumen terminating near the distal end of the catheter and a separate second lumen terminating proximally at a point spaced from the distal end of the first lumen.

The proximal end of at least one lumen includes a connector configured to electrically interconnect an electrode at the distal end of that lumen with a nerve stimulator, such as an electrical pulse generator. At least one of the lumens is also configured to receive liquid medications.
