Abstract: Systems and methods are described for generating record clusters. The methods comprise receiving a plurality of records from data sources and providing at least a subset of the records to a scoring model that determines scores for various pairings of the records, a score for a given pair of the records representing a probability that the given pair of records contain data elements about the same entity. The method further comprises generating a graph data structure that includes a plurality of nodes, individual nodes representing a different record from the records. The method also comprises assigning a different unique identifier to individual clusters of the final clusters and responding to a request for data regarding a given entity by providing aggregated data elements from those records of the records associated with a cluster of the final clusters having an identifier that represents the given entity.

Abstract: An active material useful in an oxidative dehydrogenation reactor system has an active phase, and a mixed metal oxide support phase. The active phase includes a transition metal oxide such as manganese oxide, which is reversibly oxidizable and/or reducible between oxidized and reduced states. The support phase includes a mixed metal oxide of a two or more IUPAC Group 2-14 elements. The active phase can also include a promoter such as Na-WO4 and/or a selectivity modifier such as Al or ceria. Also, a reactor including the active material in a reactor, a method of making the active material, and a method of using the active material in a regenerative reaction process.

Abstract: Systems and methods are provided for using a reverse flow reactor (or another reactor with flows in opposing directions at different parts of a process cycle) for pyrolysis of hydrocarbons. The systems and methods can include a reactor that includes a combustion catalyst to initiate and/or maintain combustion within the reactor in a controlled manner during the heating and/or regeneration portion(s) of the reaction cycle. A fuel can also be used that has a greater resistance to auto-combustion, such as a fuel that is composed primarily of methane and/or other hydrocarbons. During operation, the temperature in at least an initial portion of the reactor can be maintained at a temperature so that auto-ignition of the auto-combustion resistant fuel injected during the heating step(s) is reduced or minimized. This can allow combustion to be initiated when the auto-combustion resistant fuel comes into contact with the catalyst.

Abstract: An active material useful in an oxidative dehydrogenation reactor system has an active phase, a support phase, and an intermediate composite phase. The active phase includes a transition metal oxide such as manganese oxide, which is reversibly oxidizable and/or reducible between oxidized and reduced states. The support phase includes an oxide of a IUPAC Group 2-14 element. The composite phase is a mixed metal oxide of the transition metal and the Group 2-14 element. The active phase can also include a promoter such as Na-W04 and/or a selectivity modifier such as A1 or ceria. Also, a reactor including the active material in a reactor, a method of making the active material, and a method of using the active material in a regenerative reaction process.

Abstract: A reverse flow reactor (RFR) and process having a forward reaction feed cycle, a reverse reaction feed cycle, and a reverse regeneration cycle. The heat convected in the forward feed cycle matches the heat convected in the reverse flow cycles. Compared to an RFR without the reverse feed cycle, the three-cycle RPR substantially reduces the regeneration air flow rate, associated compression requirements, and the overall reactor volume, that are required.

Abstract: Systems and methods are provided for implementing machine learning techniques to distinguish a real identity, such as a set of identity information representing a real person, from a synthetic identity that may include portions of real identity information. Attributes regarding a target identity derived from a variety of retrieved data records may be provided as input to multiple machine learning models that generate scores associated with the potential of the target identity being synthetic. The scores may be combined and compared to a threshold to generate a determination of whether the target identity is a synthetic identity.
