Abstract: Methods, systems, and computer-readable media are described in which WAL records are replayed serially at the database sub-object level, thereby enabling parallelism for processes affecting a single database object without interfering with the consistency required to maintain ROS capability. WAL records are replayed serially at the B-Tree branch level, instead of existing approaches which serialize WAL record replay at the object or block level. Described examples may thereby enable multi-block operations (e.g., SPLIT) within the same B-Tree branch to be replayed in the correct sequence, thereby maintaining consistent reads during ROS. Multi-level dispatching at the object and sub-object levels may be used to minimize delays caused by operations affecting multiple branches of a database object.

Abstract: The invention relates to the discovery of a previously unknown population of adipocytes marked by active intracellular Wnt/?-catenin signaling. The present invention provides methods of making populations of adipocytes in which the proportion of these “Wnt+ adipocytes” is much higher than those in naturally occurring populations. Wnt+ adipocytes can be used to improve blood glucose control and exosomes secreted by Wnt+ adipocytes can be administered to reduce blood glucose levels in subjects in need thereof.

A delegate blockchain transaction may be broadcasted to a blockchain network that encodes: a delegator blockchain user, a delegate blockchain user; information that indicates one or more permissions that the delegate blockchain user is authorized to perform, and an attestation that the delegator blockchain user authorizes the delegation. A delegate blockchain user may generate a blockchain transaction which is digitally signed using a delegate's private key in place of a delegator's private key.

Abstract: Systems and methods are provided for detecting discrepancies in information that is displayed to a user across different webpages of an online shopping system. User interaction with the online shopping system is simulated in one example to collect data relating to webpages of the online shopping system.
