Abstract: Data that has been stored according to a DNA data storage method can be decoded using a flexible approach that supports both solitary strand mapping and cluster-based trace reconstruction. Solitary strand mapping can place strings based on integrity verification. Redundancy information can be partitioned to support error correction during the solitary strand mapping while still achieving integrity verification. Clusters with verified strands can be skipped during cluster-based trace reconstruction. Useful for increasing the accuracy of the trace reconstruction procedure.

Abstract: A method, computer program product, and a system where a processor(s) obtains a universe of social media items posted to a social media platform at a given time. The processor(s) determines a likelihood of each item of the universe of social media items becoming viral by linking each item of the universe to a breakout pattern based on predefined dimensions and bucketing each item into a defined grouping by a measure of anticipated virality of the item. The processor(s) applies a susceptible-infected-recovered (SIR) model as a differential equation to the bucketed items to determine an equilibrium and one or more breakout points. The processor(s) determines if a social media item will become viral based on whether the item matches at least one or the one or more breakout points.

Abstract: Disclosed herein are embodiments of systems, methods, and products comprises a server, which identifies optimized potential suppliers based on the client's request. The request comprises search specification and preselected bidders. The server extracts a first set of keywords from the search specification and finds web pages of potential suppliers based on the first set of keywords. The server identifies the websites of the preselected bidders, extracts a second set of keywords from the websites, and finds web pages of more potential suppliers based on the second set of keywords. The server determines the web pages are associated with real suppliers by excluding non-supplier web pages. The server determines a similarity score for each potential supplier by vectorizing keywords extracted from the supplier's web pages. The server determines a risk score for each potential supplier. The server generates a GUI comprising a list of suppliers ranked based on the similarity scores.

Abstract: Provided are mechanisms and processes for performing visual search using multi-view digital media representations, such as surround views. In one example, a process includes receiving a visual search query that includes a surround view of an object to be searched, where the surround view includes spatial information, scale information, and different viewpoint images of the object. The surround view is compared to stored surround views by comparing spatial information and scale information of the surround view to spatial information and scale information of the stored surround views. A correspondence measure is then generated indicating the degree of similarity between the surround view and a possible match. At least one search result is then transmitted with a corresponding image in response to the visual search query.

Abstract: Policy entries are provided in a policy table for respective geolocations. Audit data entries are generated in an audit table, including a retention period entry generated in response to looking up a retention period entry in the policy table for a first geolocation. In response to copying data to a second geolocation, a retention period audit data entry is generated in the audit table for the data at the second geolocation based on a synchronization policy entry in the policy table. A process causes deletion of the copy at the second geolocation based on an age indicated by the retention period audit data entry for the data at the second geolocation.

Abstract: A method and a server system for creating consistent snapshots in a distributed storage system are disclosed. The server system stores entities in databases that includes a production portion for storing current versions of entities and a backup portion for storing backup versions of modified entities, receives a request for a snapshot of a portion of the databases at a predefined snapshot time. In response to the request, the server system generates a snapshot of the databases, the snapshot including: a backup version of an entity retrieved from the backup portion and a current version of another entity retrieved from the databases and produces a response to the request based on the snapshot. When there are several backup portions, a backup portion may be used separately or in conjunction with other backup portions to provide required backup versions to generate a snapshot.

Abstract: Embodiments use a visual cue to identify a record with missing information among a plurality of hierarchical records. Each record includes a parent field and an associated records field. An entry in the parent field identifies a parent record of a given record. An entry in the associated records field identifies records that are associated with the record based on a criterion or one or more predetermined criteria. For a selected record, a first group of records are identified based on the parent field of the selected record. The entries in the associated records field of the selected record are then compared to the first group of records. A missing record missing an entry in the associated records field is identified among the first group of records. When the first record and the first group of hierarchical records are graphically represented on a target output medium, the missing record is represented using a visual cue.
