Abstract: A method for generating samples for an anomaly detection system includes receiving events that occurred during a time series of a target metric. Each respective event includes an event attribute characterizing the respective event. The method includes generating a set of event groups for the events. Each event shares a respective attribute with one or more other events of the respective event group. For each respective event group of the set of event groups, the method includes determining an influence pattern that identifies an influence of the respective event group on the target metric. The method includes clustering the set of event groups into event clusters based on a respective influence pattern of each respective event group. Each event cluster includes one or more event groups that share a similar influence pattern. The method includes generating training samples for an anomaly detection system based on a respective event cluster.

Abstract: A method and system for executing database queries in parallel using a shared metadata store. The metadata store may reside on a master node, and the master node may distribute this metadata with query plans to worker nodes. The worker nodes may request additional metadata from the master node when necessary.

Abstract: Techniques are disclosed for handling database queries from multiple different application versions using a single database. A computer system executing a database management system (DBMS) may receive a database query for a database, where the database query is received from a particular version of an application having a plurality of versions. The database query may specify the particular version. The computer system may then identify catalog tables, where the catalog tables include version information columns storing version access information. The computer system may determine that version access information for the database query indicates that one or more database objects corresponding to the database query are accessible to the particular version of the application.

Abstract: Techniques are disclosed relating to concurrently processing transactions. A computer system may maintain a database table having a plurality of versions. Each of the versions may identify a corresponding portion of the database table that transactions associated with that version are permitted to access. The computer system may receive a first request to perform a first transaction to modify a definition of the database table. The computer system may receive a second request to perform a second transaction to modify data stored in the database table. In response to determining that the first and second transactions are associated with different versions of the plurality of versions, the computer system may concurrently process the first and second transactions.

Abstract: A method and system for executing database queries in parallel using a shared metadata store. The metadata store may reside on a master node, where the master node is the root node in a tree. The master node may distribute query plans and query metadata to other nodes in the cluster. These additional nodes may request additional metadata from each other or the master nodes as necessary.

Abstract: A recovery system and method with repeating communication functionality includes a station configured to send a first message and at least a first remote transmitting unit responsive to the central station and configured to transmit a second message to a locating unit. At least a second remote transmitting unit includes a receiver which receives the second message, a controller configured to process the second message, and a transmitter for transmitting a third message to the locating unit.

Abstract: A system includes a normal behavior characterization module configured to receive values for a first metric of a plurality of metrics and generate a baseline profile indicating normal behavior of the first metric based on the received values. The system also includes an anomaly identification module configured to identify an anomaly in response to present values of the metric deviating outside the baseline profile. The system also includes an anomaly behavior characterization module configured to analyze a plurality of prior anomalies identified by the anomaly identification module and develop a model of the anomalies of the first metric. The system also includes an anomaly scoring module configured to determine a first score for a present anomaly detected by the anomaly identification module for the first metric. The first score is based on characteristics of the present anomaly and the model of the anomalies of the first metric.

Abstract: The present disclosure relates to cellular compositions that are modified to introduce a nucleic acid or vector expressing the same. Such compositions may be used to deliver nucleic acid to a target cell and treat disease such as cancer.

Abstract: A system includes a windowing module that divides time series data for each metric into portions. Each portion corresponds to a respective window of time. A hash module calculates a hash value for each of the portions for each of the metrics. An identification module compares the hash values for each pair of metrics and, for a selected pair of metrics, counts how many windows of time in which the hash values of the selected pair of metrics are equal. A pair is identified as a candidate pair in response to the count exceeding a threshold. A metric graph module creates a first edge in a graph based on the candidate pair of metrics. Each of the metrics is a node in the graph and direct relationships between each pair of the metrics are edges in the graph. An anomaly combination module analyzes an anomaly condition based on the graph.

Abstract: Method and systems for analyzing event log elements are provided. In one example, a method includes receiving an event log element in a computer. A similarity index is calculated between the event log element and a text element. A threshold of similarity is calculated. The similarity index is compared to the threshold. If the similarity index is greater than the threshold, the event log element is grouped into a cluster with the text element to create a file of cluster assignments.
