Abstract: Systems and methods for determining position and orientation of a bone of an anatomical feature are described. These include the use of a wearable holder configured to be mounted about an outer-skin surface of the anatomical feature, such that the anatomical feature and the bone are positioned in fixed relation with respect to the wearable holder when the wearable holder is mounted about the anatomical feature. Reference marker arrays are fixedly mounted to the wearable holder, each being positioned on the wearable holder to identify a landmark of the bone within the wearable holder when the wearable holder is mounted to the anatomical feature. The position and orientation of the reference markers are trackable to determine position and orientation of the wearable holder in a reference coordinate system, thereby enabling position and orientation of the landmarks on the bone to be determined.

Abstract: Method, computer program product, and computer system are provided. Traffic is collected against a NoSQL database by an activity collector. A database transaction log is periodically extracted and analyzed. The collected traffic and the analyzed database transaction log are input to building a knowledge base of database access patterns. Current traffic is captured and used to compute an activity threshold. Traffic is directed to a workload processor based on the activity threshold. Traffic is directed to an intensive insert/update/delete (IUD) processor in response to the activity threshold exceeding a configured threshold. A plurality of temporary shards is generated along with an adaptive key and adaptive index in the plurality of temporary shards. The intensive IUD processor traffic is re-directed to the plurality of temporary shards while the activity threshold exceeds the configured threshold.

Abstract: Embodiments of this application disclose a stator, a stator manufacturing method, a motor, and an electric vehicle. The stator includes: a stator tooth part, where a plurality of stator tooth parts are arranged at intervals along a circumferential direction; and a stator yoke part, where the stator yoke part is disposed along a circumferential direction of the stator tooth part, and the circumferential direction is a circumferential direction around a central axis of the stator; where the stator tooth part and the stator yoke part are integrally formed by an oriented silicon steel sheet, and a grain direction of the formed oriented silicon steel sheet points to the central axis of the stator along a radial direction. Therefore, the stator tooth part and the stator yoke part are formed by using one material, and there is no need to splice two materials, thereby reducing process costs.

Abstract: A preparation method for and an application of a modified siloxane-based supercritical carbon dioxide thickener are disclosed. The method includes the following steps: using 1,3-diallyl-1,3,5-triazine-2,4,6-trione as a polymerization monomer, and dropwise adding 1,3,5,7-tetramethylcyclotetrasiloxane for hydrosilylation in the presence of a catalyst to obtain a modified siloxane polymer. The obtained modified siloxane polymer is directly used as a supercritical carbon dioxide thickener without purification post-treatment; when in use, the modified siloxane polymer is prepared into a solution with a concentration of 1-2%, has an excellent thickening effect with no cosolvent required, and has high solubility in carbon dioxide and high temperature resistance.

Abstract: The present invention relates to use of slow-releasing hydrogen sulfide organic donor ADT-OH drugs in the differentiation of neural precursor cells. ADT-OH can induce more directed differentiation of neural precursor cells into neurons and oligodendrocytes and less differentiation into astrocytes, promote the axon growth of neurons, and reduce the death of neural precursor cells, thereby providing a direction for the transplantation of neural precursor cells to repair damaged nerves. ADT-OH will likely become a new drug target for the clinical treatment of nervous system diseases.
