Abstract: Described apparatuses and methods track access metadata pertaining to activity within respective address ranges. The access metadata can be used to inform prefetch operations within the respective address ranges. The prefetch operations may involve deriving access patterns from access metadata covering the respective ranges. Suitable address range sizes for accurate pattern detection, however, can vary significantly from region to region of the address space based on, inter alia, workloads produced by programs utilizing the regions. Advantageously, the described apparatuses and methods can adapt the address ranges covered by the access metadata for improved prefetch performance. A data structure may be used to manage the address ranges in which access metadata are tracked. The address ranges can be adapted to improve prefetch performance through low-overhead operations implemented within the data structure.

Abstract: The present technology relates to surgical drilling devices, and associated systems and methods. In some embodiments, a surgical drilling device includes a drill bit and a retraction mechanism. The retraction mechanism can include a housing, a slide assembly within the housing and operably coupled to the drill bit, a spring element engaging the slide assembly, and a locking element coupled to the slide assembly. The locking element can be movable between a locked configuration and an unlocked configuration based on an amount of force applied by the drill bit to the slide assembly. When in the locked configuration, the locking element can secure the slide assembly to the housing. When in the unlocked configuration, the locking element can allow the spring element to displace the slide assembly proximally within the housing to retract the drill bit.

Abstract: Embodiments of the present disclosure relate to techniques for neuromodulation delivery. Based on image data acquired from the subject, control parameters controlling energy application of neuromodulating energy may be dynamically changed during the course of the delivery to maintain desired characteristics of the neuromodulating energy. For example, the beam of the neuromodulating energy may be dynamically adjusted to account for movement of an organ during breathing. In another embodiment, a desired region of interest is identified within the subject based on a trained neural network and the acquired image data.

Abstract: Disclosed in some examples are methods, systems, memory devices, and machine-readable mediums that allows an application thread to indicate an undo logging operation when calculations are beginning that may need to be rolled back if a crash or other failure occurs. During the undo logging operation, memory writes an identified memory are done to a copy and the original value is preserved. If the undo logging operation is committed, then the copy becomes the correct value and may then be subsequently used in place of the original, or the value stored in the copy is copied to the original. If the undo logging operation is abandoned, the copy is not preserved and the value goes back to the original.

Abstract: The present invention provides methods and systems for determining the weight of a vehicle.

Abstract: Described apparatuses and methods order memory address portions advantageously for cache-memory addressing. An address bus can have a smaller width than a memory address. The multiple bits of the memory address can be separated into most-significant bits (MSB) and least-significant bits (LSB) portions. The LSB portion is provided to a cache first. The cache can process the LSB portion before the MSB portion is received. The cache can use index bits of the LSB portion to index into an array of memory cells and identify multiple corresponding tags. The cache can also check the corresponding tags against lower tag bits of the LSB portion. A partial match may be labeled as a predicted hit, and a partial miss may be labeled as an actual miss, which can initiate a data fetch. With the remaining tag bits from the MSB portion, the cache can confirm or refute the predicted hit.

Abstract: Methods and systems for providing content are disclosed. One method can comprise receiving a request for content comprising at least a first segment. The method can also comprise determining an expiration condition of the first segment, and replacing the first segment with a second segment based on the expiration condition. The method can also comprise providing the second segment to a user or a device.

Abstract: An electronic trading system is configured to trade credit default swap (CDS) futures contracts on an open exchange. The CDS futures contract allows the buyer and seller isolate and trade the credit risk of a third party. The third pay may be a corporation, sovereign government, or any entity that issues bonds or notes. The CDS futures contract seller effectively pays the premium over time in increments determined by market rates and through the natural operation of the open market. The CDS futures contract buyer makes a contingency payment if the CDS futures contract goes in-the-money (ITM). Both sides of the contract are guaranteed by the exchange as a counterparty.

Also disclosed are compositions containing the compounds of Formula 1 and methods for controlling undesired vegetation comprising contacting the undesired vegetation or its environment with an effective amount of a compound or a composition of the invention.

Abstract: Systems and methods are disclosed for providing voice and noise activity detection with audio automixers that can reject errant non-voice or non-human noises while maximizing signal-to-noise ratio and minimizing audio latency.

Abstract: A cache memory can maintain multiple cache lines and each cache line can include a data field, an encryption status attribute, and an encryption key attribute. The encryption status attribute can indicate whether the data field in the corresponding cache line includes encrypted or unencrypted data and the encryption key attribute can include an encryption key identifier for the corresponding cache line. In an example, a cryptographic controller can access keys from a key table to selectively encrypt or unencrypt cache data. Infrequently accessed cache data can be maintained as encrypted data, and more frequently accessed cache data can be maintained as unencrypted data. In some examples, different cache lines in the same cache memory can be maintained as encrypted or unencrypted data, and different cache lines can use respective different encryption keys.

Abstract: A filtration system can include a loading member configured to receive a plurality of filtration members which can be sequentially moved from a non-active position in which a respective one of the plurality of filtration members is not in fluid communication with a sample flow path of the cell removal system, to an active position in which the respective filtration member is in fluid communication with the sample flow path, and to a discarded position in which the respective filtration member has been removed from fluid communication with the sample flow path.

Abstract: Described apparatuses and methods control a voltage or a temperature of a memory domain to balance memory performance and energy use. In some aspects, an adaptive controller monitors memory performance metrics of a host processor that correspond to commands made to a memory domain of a memory system, including one operating at cryogenic temperatures. Based on the memory performance metrics, the adaptive controller can determine memory performance demand of the host processor, such as latency demand or bandwidth demand, for the memory domain. The adaptive controller may alter, using the determined performance demand, a voltage or a temperature of the memory domain to enable memory access performance that is tailored to meet the demand of the host processor. By so doing, the adaptive controller can manage various settings of the memory domain to address short- or long-term changes in memory performance demand.
