Abstract: A persistent connection is used for real-time or near real-time data transfer from a push platform on a network to a mobile station. To establish and maintain the persistent connection between the mobile station and push platform on the network, various protocols are defined over a packet connection between the mobile station and push platform. The real-time or near real-time data is pushed or sent by the push platform to the mobile station, as the data becomes available from a data source. In particular, heartbeat messages are used to determine whether or not the persistent connection is alive and available for real-time or near real-time data transfer. When the persistent connection is lost, the mobile station uses a retry connection scheme based on the number of connection attempts made by the mobile station for establishing a new persistent connection to the push platform.

Abstract: To provide a system by which evaluation of circumstances of contamination by microparticles having nucleic acid can be performed rapidly and accurately. The theme is achieved by a system for measuring microparticles that includes: (1) a microparticle adhesion step of adhering the microparticles having nucleic acid to a microparticle adhesion member; (2) a membrane breakage step of breaking membranes of the adhered microparticles by electrical discharge; (3) an electrophoresis step of electrophoresing the microparticles in a thickness direction of a gel to make the nucleic acid in the microparticles migrate from a negative electrode side toward a positive electrode side and adhere the nucleic acid on a surface of a nucleic acid detection member; and (4) a nucleic acid measurement step of fluorescently staining the surface of the nucleic acid detection member to measure a concentration of the nucleic acid.
