Abstract: A method comprises storing first transaction data for a first transaction producing a first version of a first dataset, second transaction data for a second transaction transforming a first version of the first dataset to a second version of the first dataset, and third transaction data for a third transaction transforming the second version of the first dataset to a third version of the first dataset; storing dependency information indicating a first dependency of the third transaction on the second transaction and a second dependency of the second transaction on the first transaction; receiving a first instruction to revoke a first permission of a first user to access the second version of the first dataset; automatically revoking a certain permission of the first user to access the third version of the first dataset based on the dependency information.

Abstract: At switch-on or when recovering from lack of coverage, a UE determines first frequency bands corresponding to an initial MCC of a country in which the UE currently is located (402). The frequency bands include a first set of frequency bands associated with a network carrier to which the UE is subscribed and a second set of frequency bands not associated with the network carrier (404). The UE scans the first set of frequency bands (406). In response to detecting a new MCC and determining that no service is available within the first set of frequency bands (408), the UE scans a third set of frequency bands preferred by the UE within a second plurality of frequency bands corresponding to the new MCC (410). In response to determining that no service is available within the third set of frequency bands, the UE scans the second set of frequency bands (412).

Abstract: The present invention is a unique sequential process for treating carbon and alloy steels to improve resistance to tribological stresses while reducing conventional processing time required to obtain articles having a similar hardness. This process comprises carburizing or carbonitriding the article, tempering the carburized or carbonitrided article, net-shaping (machining) the tempered article, and plasma (ion) nitriding the tempered article for a significantly reduced period of time versus conventional plasma (ion) nitriding.
