Abstract: A system can receive a request, and identify an attribute-based access control policy comprising a permission policy and a condition policy that is associated with performing an operation with respect to a group of computing resources with a first scope of the operation. The system can determine whether the account satisfies the permission policy for the operation, wherein determining whether the account satisfies the condition policy evaluates to true based on account attributes of the account and resource attributes of the group of computing resources in the first scope of the query operation. The system can, in response to determining that the account satisfies the condition policy, send an indication of the request as constrained by the first scope and a second scope that is based on the condition policy to a service, the service performing the operation to produce a result, and responding to the request with the result.

Abstract: A data management method, a system, and a device are provided. An example method includes: A data storage entity receives a data access request and sends an access permission verification request to a distributed ledger node storing a data access policy of the client and/or a data access policy of the user. The distributed ledger node verifies, based on an identifier of a client and/or an identifier of a user in the access permission verification request and a distributed ledger, whether the client has data access permission, and sends a first access permission verification response to the data storage entity if the client has the data access permission, where the first access permission verification response indicates that the client has the data access permission. After receiving the first access permission verification response sent from the distributed ledger node, the data storage entity sends corresponding data to the client.

Abstract: The present disclosure provides compositions and methods of inactivating a lipid enveloped virus in a product feedstream in a manufacturing process of a therapeutic protein using environmentally compatible detergents. The present disclosure provides a detergent mixture comprising two environmentally sustainable detergents: n-Octyl-?-D-Glucopyranoside (OG) and n-Dodecyl-?-D-Maltopyranoside (DDM). The performance of this OG:DDM detergent combination is superior to that of Lauryldimethylamine Oxide (LDAO), ECOSURF™ EH9, or Triton X-100 in the purification of therapeutic proteins such as abatacept and belatacept. OG:DDM combinations are highly effective for viral inactivation, while having essentially no impact on protein stability, protein charge distribution (e.g., sialic acid levels), impurity clearance, protein deamination, or protein oxidation. Accordingly, combinations of OG and DDM can be used as substitutes of Triton X-100 for viral inactivation steps in the production of biologics.

Abstract: Apparatuses and techniques for controlling usage-based disturbance mitigation are described. In an example aspect, usage-based disturbance mitigation is performed between activation and precharging of a row. More specifically, usage-based disturbance circuitry performs an array counter update procedure while the row is active. The techniques for controlling usage-based disturbance mitigation control timing of the array counter update procedure at a multi-bank level or a local-bank level. Additionally, the techniques for controlling usage-based disturbance mitigation control a timing of a precharging operation to ensure completion of the array counter update procedure. The techniques for controlling usage-based disturbance mitigation are not limited to the array counter update procedure and can generally be applied to other aspects of usage-based disturbance mitigation, such as bit-error detection and/or correction.
