Abstract: A system for database reversion is described. The system comprises: a database engine configured to host an active database; a log engine configured to generate transaction logs for transactions affecting the active database; a backup engine configured to create a backup data structure to allow for database reversion; and a memory buffer separate from the active database. A page in the active database has an associated page timestamp indicating a most recent update of the page in the active database. The database engine is configured to flush an updated copy of a page in the memory buffer to the active database. The backup engine is configured to, prior to the flush, store an image of the page in the active database to the backup data structure when the page in the active database is older than the time value related to the creation time of the backup data structure.

Abstract: A result ranking system can include a computing device that is configured to obtain a plurality of items based on a query and a value corresponding to each item of the plurality of items. The computing system can also be configured to retrieve a value distribution corresponding to the query and generated based on customer interaction data. The computing system can also, for each item of the plurality of items, determine a feature value based on the value distribution and the corresponding value of the item. The computing system can be further configured to transmit the plurality of items to a customer device for display in an arrangement based on the corresponding feature value.

Abstract: Systems and methods including one or more processors and one or more non-transitory storage devices storing computing instructions executed by the one or more processors can perform functions comprising: storing a category classification hierarchy that classifies items into a plurality of browse categories; monitoring user engagement metrics for each of the items; using the user engagement metrics to compute shelf importance signals for the items; executing a ranking engine that generates a ranked item listing for a browse category based, at least in part, on the shelf importance signals for the items; and transmitting the ranked item listing for the browse category to a computing device. Other embodiments are disclosed herein.

Abstract: A high-speed multiplexor comprises a set of differential input pairs to receive and mix a set of differential input signals at a differential output node pair. The high-speed multiplexer further comprises an active inductive load pair driven by the input stage using the mixed set of differential input signals. Each active inductive load comprises a p-channel field effect transistor (pFET) device connected to one of the differential output node pairs and a resistor connected between a gate node and a drain node of the pFET device. The multiplexer further comprises a first cross-coupling capacitor connected between the gate node of a first inductive load and a second output node of the differential output node pair and a second cross-coupling capacitor connected between the gate node of a second inductive load and a first output node of the differential output node pair.

Abstract: According to an example, with respect to decentralized supply chain for three-dimensional printing based on distributed ledger technology, three-dimensional printing constraints may be ascertained for a three-dimensional part to be printed, and a plurality of attributes for three-dimensional printers may be ascertained. The three-dimensional printing constraints may be compared to each attribute of the plurality of attributes. A determination may be made as to whether the three-dimensional part is printable by at least one three-dimensional printer or not printable by any three-dimensional printer. Costs associated with three-dimensional printing of the three-dimensional part and non-three-dimensional printing based manufacturing of the three-dimensional part may be ascertained. A determination may be made as to whether the three-dimensional part is to be printed by the at least one three-dimensional printer.
