Abstract: The present invention provides for a heavy truck tire tread (12) with a plurality of sipes (20) in the shoulder rib (18) that extend from the shoulder edge (14) to the shoulder groove (16). Each one of the sipes (20) has a bottom (28) with a teardrop (30) located at the bottom, and the bottom (28) does not extend the same depth in the thickness direction across the entire lateral length of the sipe (20). The bottom (28) at a middle of the sipe (20) extends for less of a depth in the thickness direction than does the bottom (28) at a shoulder edge (14) portion of the sipe (20) located outboard from the middle of the sipe (20) in the lateral direction. The bottom (28) at the middle of the sipe (20) extends for less of a depth in the thickness direction than does the bottom (28) at a shoulder groove (16) portion of the sipe (20) located inboard from the middle of the sipe (20) in the lateral direction.

Abstract: A tread for a heavy truck tire is provided that has a bottom surface (14), a shoulder rib (16), and a sacrificial rib (20) located outboard from the shoulder rib (16) in a width direction. A decoupling void (30) is located between the shoulder rib (16) and the sacrificial rib (20). First decoupling void sipes (32), second decoupling void sipes (100) and third decoupling void sipes (104) are in the shoulder rib (16), and one second decoupling void sipe (100) is between one first decoupling void sipe (32) and one third decoupling void sipe (104). The first and third decoupling void sipes (32, 104) are closer to the bottom surface (14) than is the decoupling void (30) in the thickness direction. The second decoupling void sipe (100) is not closer to the bottom surface (14) than is the decoupling void (30) to the bottom surface (14) in the thickness direction.

Abstract: According to some embodiments, a system to manage database management system backups may include a plurality of database services. For each database service, a database backup resource (e.g., a human-readable structured document) may specify desired backup state information (e.g., a buffer size, a schedule, an amount of memory, etc.). A stateless backup operator component may then compare a present backup state of each database service with the associated desired backup state information. When a mismatch is identified between the present backup state of a database service and the associated desired backup state information, that database service may be automatically reconfigured (e.g., in connection with a recover job, backup job, backup configuration job, keystore backup job, etc.) in accordance with the desired backup state information.

Abstract: A tread (12) for a heavy truck tire is provided that has a bottom surface (14), a shoulder rib (16), and a sacrificial rib (20) located outboard from the shoulder rib (16) in a width direction. A decoupling void (30) is located between the shoulder rib (16) and the sacrificial rib (20). A decoupling void sipe (32) is in the shoulder rib (16) and opens at the shoulder rib upper surface (18) and at the decoupling void (30). The decoupling void sipe (32) extends in the thickness direction and is closer to the bottom surface (14) than the decoupling void (30) in the thickness direction.

Abstract: A system and method to receive, by a database service from an encryption service of a database provider in a cloud environment, an encryption key passphrase stored in a secure storage separate and distinct from a database persistence and object store of the database service, the encryption key passphrase used as a key to encrypt and decrypt a key storage of the database service that stores one or more keys used by the database service; and to use the encryption key passphrase by a recovery service of the database provider in the cloud environment to recover the database service and its associated key storage.

Abstract: A tower for a wind turbine is disclosed, said wind turbine comprises the tower, a nacelle and a rotor having at least one rotor blade. The tower is configured for supporting the nacelle and the rotor on a support system. The tower itself may be structured as having an upper top end for supporting the nacelle and a lower support end for being placed on the support system. Electric energy generated is transported via power cables from the nacelle to an electric grid, preferably via power electronic components, switches and/or transformers. Furthermore, the nacelle may rotate around the yaw axis according to the current wind direction. Hence, the rotation of the nacelle introduces a twist into the power cables, wherein said twist causes a deviation (shortening) in the length of the power cables. Furthermore, the tower comprises at least one radial cable guiding device for receiving the cable and a cable support arrangement for supporting the cable in a beneficial manner.

Abstract: A heavy truck tire tread is provided that has a rolling direction that is in a longitudinal direction of the tread. A circumferential sipe (20) is present and extends in the longitudinal direction completely around the tread. The circumferential sipe does not bound a sacrificial rib. A plurality of micro sipes (22) engage the circumferential sipe and are located on opposite sides of the circumferential sipe in the lateral direction. The micro sipes extend from the circumferential sipe so as to terminate within rubber of the tread at a terminal end.

Abstract: Described is a system that securely recovers critical backup and data protection infrastructure such as a backup application that manages data for a backup and recovery system. Such a capability may be provided by securely storing a copy of metadata associated with a production backup application into an isolated recovery environment. By storing the metadata on the isolated recovery environment, the metadata may be secure from potential security threats such as ransomware that may attack the production infrastructure itself. Accordingly, the secure copy of metadata may then be restored to a sandboxed environment with the isolated recovery environment and used to create a recovery instance of the backup application. The system may also perform various tests on the recovered instance of the backup application in response to particular security threats before being exposed to a production system for recovery purposes.

Abstract: Described is a system that provides a mechanism to securely deliver software updates to components of an isolated recovery environment. More specifically, the system provides the ability to include (or inject) a software update as part of a secure data transmission from a production environment to an isolated recovery environment. The data transmission may use existing infrastructure for synchronizing recovery data between the production backup system and isolated recovery system thereby preventing a potential new access point (or vulnerability) to the isolated recovery environment that a cyber security threat may attempt to exploit.

Abstract: The disclosure generally describes methods, software, and systems for performing automatic backups to the cloud. Application code in a database system updates rows and columns in the database for an updated object, and automatically performs a backup of database information to the cloud. Performing the backup includes directly executing a REST call to the cloud storage solution to which the backup of the database information is performed. Performing the backup includes: sending a request, using a REST call, to create a new object in the cloud storage solution; in response to receiving an acknowledgement of a successful creation of the new object, sending, to the cloud storage solution, REST PUT calls that include contents of the object for the cloud storage solution to store into the created new object; receiving, from the cloud storage solution, a specific key identifying the backup; and locally storing the specific key.

Abstract: The present invention provides for a heavy truck tire tread having a shoulder edge, shoulder groove, and shoulder rib therebetween. A plurality of sipes are in the shoulder rib and are oriented less than 20 degrees to the lateral direction. The sipes are spaced from one another between 5 to 18 millimeters in the longitudinal direction. Additionally or alternatively, the sipes are arranged so that a reference plane extends through a sipe bottom point and a sipe top point at the average sipe line. A sipe inclination line extends from the sipe bottom point to the sipe top point, and a reference line extends through the sipe bottom point. A sipe inclination angle is defined by the reference line and the sipe inclination line and is greater than 0 degrees.
