Abstract: Methods, apparatus, and computer readable media related to determining that no resources responsive to a query of a user at a first time satisfy one or more criteria (e.g., one or more quality criteria) and, in response to such a determination: providing for presentation to the user at a later time, content that is based on a given resource that is responsive to the query at the later time and that satisfies the criteria. The given resource that is responsive to the query at the later time may be a resource that is in addition to any resources responsive to the query at the first time or may be a refined version of a resource that was responsive to the query at the first time.

Abstract: A data catalog system is disclosed that provides capabilities for uniquely identifying and retrieving data entities stored in diverse data sources managed by an organization. The data catalog system includes capabilities for generating a unique external identifier for a data entity (e.g., a data asset or a data object) by identifying a set of immutable configuration parameters associated with the data asset and identifying a set of data object attributes that uniquely identify data objects within the data asset. The generated unique external identifiers are stored as part of the metadata harvested by the data catalog system. The external identifiers are used to enforce a single representation of the data assets and the data objects in the data catalog system. The external object identifiers are used to perform data lookups and reconcile states of data entities during the metadata harvesting process.

Abstract: A calculation engine of a database management system is described that determines a multiprovider includes a first data source and a second data source that each require different approaches for operation optimization. The calculation engine can split the multiprovider into a first node corresponding to a first operation compatible with the first data source and a second node corresponding to a second operation compatible with the second data source. The calculation engine can perform the first operation at the first data source to produce a first result and perform the second operation at the second data source to produce a second result. The calculation engine can then merge the first result and the second result according to a third operation, and perform such third operation at the first data source.

Abstract: The present disclosure relates to a method for data synchronization between a source database system and target database system, wherein execution of a database transaction of the source database system is complete if a processing step followed by an application step of the database transaction is performed.

As described, the ingestion system includes an ingestion module, a flat file module, a compliance module, and a deduplication module wherein the modules together ingest a flat file data object, parse and process a renderable data object from the flat file data object, and store the renderable data object in a renderable object database.

Abstract: The detection of a risky edge in a lateral movement path is detected by determining the weakest point in the configuration of the user accounts, groups, and devices having access to the resources of a tenant of the cloud service. A lateral movement graph having nodes of user accounts, devices, and groups and edges representing relationships between the nodes is used to compute a risk score for each edge in the graph. The risk score of an edge is used to identify a weak connection and potential target for a lateral movement attack.

Abstract: The present disclosure is directed to a leader-based partially synchronous BFT SMR protocol that improves upon existing protocols by exhibiting two rounds of communication latency, linear authenticator complexity, and optimistic responsiveness. This is achieved through the novel use of an aggregate signature scheme as part of the protocol's view-change procedure.

Abstract: In some examples, a first storage system receives a transfer of a synchronous replication role and an asynchronous replication role of a second storage system to the first storage system, where in the synchronous replication role the second storage system is to synchronously replicate data to the first storage system, and in the asynchronous replication role the second storage system is to asynchronously replicate a first data storage object to a third storage system. The first storage system uses, at the first storage system, translation information to identify a second data storage object that the second storage system is to asynchronously replicate to the third storage system following the transfer.

Abstract: A unified framework for healthcare workflows to introduce multiple integrated approaches to error analysis.

A second approach uses process mining to extract maximum information about process diagrams and process bottlenecks.

Abstract: Methods and apparatus related to determining additional features for a user task entry of a user based on a user habit of the user. For example, one or more aspects of a user task entry of a user may be compared to one or more aspects of a user habit of the user to determine a correlation measure between the task entry and the user habit. If the correlation measure satisfies a threshold, one or more additional features of the user task entry may be determined based on the user habit. For example, the user habit may include one or more trigger indicators that indicate an actual entry or anticipated entry of the user into the user habit, and one or more of the trigger indicators may be utilized to determine task trigger indicators for the user task entry.

Abstract: Embodiments of the present invention relate to synchronously replicating data in a distributed computing environment. To achieve synchronous replication both an eventual consistency approach and a strong consistency approach are contemplated. Received data may be written to a log of a primary data store for eventual committal. The data may then be annotated with a record, such as a unique identifier, which facilitates the replay of the data at a secondary data store. Upon receiving an acknowledgment that the secondary data store has written the data to a log, the primary data store may commit the data and communicate an acknowledgment of success back to the client. In a strong consistency approach, the primary data store may wait to send an acknowledgement of success to the client until it receives an acknowledgment that the secondary has not only written, but also committed, the data.

Abstract: Methods and systems for execution of data operations in a queue are described. One method includes loading a pointer to a record in a lock-free ring buffer by an executing thread, as well as calculating an index from the pointer to a record to be processed and obtaining a header of the record to be processed. Based on the header, a state of the record to be processed is determined from among: a filled state, a filling state, a drained state, and a draining state. A candidate header is created which includes an updated state indicating that the record is in use by the executing thread. An atomic operation is performed to update the header of the record to the candidate header. Upon successful completion of the atomic operation to update the header of the record to the candidate header, a data operation is performed on the record.

Abstract: A screen reader application traverses each node in a document object model (DOM) for the text stylization. Properties for foreground color, background color, font type, font size and font stylization are algorithmically reduced to an identifier. Each node in the DOM with the same identifier has the same text stylization. Unique and infrequent text stylizations by a webpage author signal a point of interest. The screen reader application locates and navigates to that node in the DOM on behalf or in response to the end user. Points of interest are further identified by a number of additional factors. A first includes percentage of text of having the text stylization versus total text in the DOM. A second includes excluding candidate point of interest nodes having more than 250 characters. Others include imposing minimum font sizes and text contrast ratios to qualify as a point of interest.

Abstract: A spreadsheet supports formulas in cells that trigger queries of a data source. The parameters for queries can include or depend on values in other cells in the spreadsheet. Thus, the precise query submitted to the data source is dynamic, being dependent on the data and formulas in the spreadsheet. Furthermore, on receiving the query results, they are added to cells in the spreadsheet, which can be parameters for other queries defined in other cells. Changing the value of a single cell can automatically trigger an update of an arbitrarily deep hierarchy of calculations that can include an arbitrary number of data source queries.
