摘要:
A method and apparatus for migrating the session state of an original session from a first node to a second node, such that a process, executing in the migrated session, may enqueue and dequeue messages from a queue of messages and experience the same behavior from the queue of messages as if the process was enqueuing and dequeuing messages in the original session. Advantageously, all the benefits of migrating a session from one node to another node may be realized, even when the session contains queuing state information that describes the state of a queue of messages. Data that indicates how many messages one or more subscribers have removed from the queue of messages may also be stored to preserve proper behavior of the queue of messages for multiple subscribers when sessions are migrated.

A vaporization system and control method are provided. Liquid cryogen is provided to first ambient air vaporizer (AAV) units. When an output superheated vapor temperature is less than a threshold, the liquid cryogen is provided to second AAV units. When greater than or equal to the threshold, it is determined whether the second AAV units are defrosted. When defrosted, the liquid cryogen is provided to the second AAV units. When not defrosted, it is determined whether ice has formed on the first AAV units. When not formed, it is again determined whether the superheated vapor temperature is less than the threshold. When formed, it is determined whether a current ambient condition is favorable to defrosting the second AAV units. When not favorable, the liquid cryogen is provided to the second bank of AAV units. When favorable, it is again determined whether the superheated vapor temperature is less than the threshold.

The invention belongs to the field of medical detection and discloses a method and device for fast detecting nucleic acid. The pathogenic microorganism nucleic acid is carried out with amplification reaction by LAMP technology in a temperature-controlled reaction tube comprising at least a sealing layer, and after the reaction is completed, the temperature of the reaction tube is raised without opening the tube to dissolve the sealing layer to release the fluorescent dye for the fluorescence detection. The method can carry out the amplification reaction and fluorescence detection directly in the instrument without taking out the reaction tube. The device has advantages of simple structure, low cost and simple operation, and can be used as a fast detecting device for the pathogenic microorganism nucleic acid.

An exemplary backlight module (300) includes a frame (350) and a bottom plate (370). One of the frame and the bottom plate includes a plurality of elastically deformable buckling structures (358), and the other of the frame and the bottom plate includes a plurality of protrusions (204, 374) corresponding to the buckling structures. When the bottom plate is attached to the frame, the bottom plate and the frame are pressed together along a first axis, and the buckling structures elastically deform and then elastically rebound such that the buckling structures are engaged with the protrusions and the bottom plate is fixed to the frame.

摘要:
Techniques for migrating duration trees from a source database server (or instance) to a destination database server (or instance) are provided. A duration is a memory management construct that allows database components to group related areas of memory together. A source duration tree is captured at the source database server and combined with a destination duration tree at the destination database server. Any duration identifiers in the source duration tree that conflict with (i.e., are the same as) a duration identifier in the destination duration tree are mapped to new duration identifiers.

A cryogenic vaporization system and a method for controlling the system are provided. The system includes a first vaporizer arrangement and a second vaporizer arrangement configured for receiving a liquid cryogen and outputting a superheated vapor. The second vaporizer arrangement is connected in parallel with the first vaporizer arrangement, and includes one or more banks of ambient air vaporizer (AAV) units or loose fill media with a high heat capacity. The second vaporizer arrangement has a different configuration than that of the first vaporizer arrangement. The system further includes at least one control valve controlling provision of the liquid cryogen to at least one of the first vaporizer arrangement and the second vaporizer arrangement.

A HCPS (hierarchically clustered P2P streaming system) comprising peers grouped into clusters and hierarchies. The HCPS actively balances the uploading capabilities among clusters and executes an optimal scheduling algorithm within each cluster to ensure that system resources are optimally utilized. The HCPS comprises an architecture which can be used in practical applications, yet can achieve the streaming rate close to the theoretical upper bound.
