Abstract: Aspects of the subject technology include a method comprising obtaining an enrollment confidence score and a validation confidence score, and determining an identity assurance score associated with the user account that indicates a level of confidence in an identity of the user. The identity assurance score is determined based at least in part on one or more of the enrollment confidence score or the validation confidence score. The method also comprises receiving, from a service provider, a request for the identity assurance score for the user account, the request corresponding to at least one of an authorization or an authentication of the user account at the service provider, and providing, responsive to the request, the identity assurance score of the user account to the service provider for at least one of the authorization or the authentication of the user account at the service provider.

Abstract: A range of Cel7 putative cellobiohydrolase genes were identified using genome mining and homologous sequence alignment to Cel7A from Trichoderma reesei. A representative subset of these genes from across a broad diversity of evolutionarily disparate sources were cloned and expressed in T. reesei using a constitutive promotor and a common secretion signal. The purified recombinant enzymes were tested for efficacy on various substrates. The top performers were subjected to structural studies and subsites likely to confer enhanced performance were predicted using homology modeling and comparisons of natural sequence diversity. Once identified, the subsites were genetically introduced individually and combinatorically into the best in class Cel7A backbone we have found to date and then expressed in T. reesei and tested. A triple mutant was determined to have the highest cellulase activity we have measured in a cellobiohydrolase to date.

Abstract: Consistent access to data objects transcending storage limitations in a non-relational data store may be provided. A data object may be stored in data chunks across separately accessible data items in a non-relational data store. Consistency indications may also be stored along with the data chunks in the data items that may be used to provide consistent access to the data object. When update to the data object is received, the data chunks and consistency indications of the data object may be retrieved and evaluated to determine if the data object is in a consistent state. If the data object is consistent, then the new versions of the data chunks and consistency indications may be generated. Authorization to update the data object may be obtained, and then the new versions stored in the data items in the non-relational data store.

Abstract: Techniques for determining an inventory level for an ordered item and offering delivery for the ordered item within a time frame may be provided. Information about a plurality of merchants may be maintained. An inventory level of the plurality of merchants for an item ordered by a customer may be determined based on the information and a threshold associated with the item. A particular merchant that is within a geographic range of the customer may be selected based on the inventory level and the merchant information. In an example, delivery instructions may be provided to a delivery service for delivering the item to the customer within the time frame.
