Abstract: A train signal system includes a first subsystem, a second subsystem, built by an LUA framework, and a control platform configured to perform communication with the first subsystem by using a first interface, perform communication with the second subsystem by using a second interface, and transmit an LUA script instruction to the second subsystem by using the second interface, so that the second subsystem executes the LUA script instruction.

Abstract: A nail gun having a driving and controlling mechanism. The driving and controlling mechanism comprises a driving assembly disposed inside a casing of the nail gun for striking nails in a striking direction; and a control assembly controlling the driving assembly. The driving assembly comprises a piston movably disposed inside the casing and attached to a striking member for striking the nails; at least one power spring in contact with the piston; a pushing component for pushing the piston towards the power spring; and a motor for rotating the pushing component. The control assembly comprises a main switch configured to produce a first electronic signal; and a safety switch configured to produce a second electronic signal. The main switch and the safety switch are in communication with the motor such that the motor is configured to operate when it receives both the first electronic signal and the second electronic signal.

Abstract: A nail gun having an energy storage mechanism for storing energy used for striking nails out of the nail gun, the energy storage mechanism comprises a guiding rod attached to a fixed plate assembly; a piston disposed on the guiding rod; a striking member mounted on the piston for striking the nails; at least one power spring disposed around an outer periphery of the guiding rod; a guide sleeve moveably disposed around the outer periphery of the guiding rod and between the power spring and the guiding rod; wherein a first end of the power spring abuts against the piston and is configured to be compressed to store energy.

Abstract: Provided is a model for evaluating the degree of liver fibrosis constructed based on bile acids. A plurality of bile acids are simultaneously detected by a liquid chromatography-tandem mass spectrometer to further improve the accuracy in combination with other liver indicators; moreover, a multiple regression analysis method is applied to establish a grading diagnosis model for the degree of liver fibrosis caused by a chronic liver disease, which can significantly improve the sensitivity and specificity of the existing non-invasive diagnosis of liver fibrosis. When the model is used to evaluate the degree of liver fibrosis of a patient, the highest AUC is up to 0.9278; the sensitivity is up to 86.79%; and the specificity is up to 89.01%. The detection results are completely consistent with the pathological results of clinical liver biopsy. Therefore, patients need not receive a liver biopsy.

Abstract: The present invention provides a system and a method for managing an expanded service characteristic bundle, which solve the problem that the WAB of a Web layer lacks the capabilities of modularization.

Abstract: The present disclosure relates to the field of computers, provides a data processing method, a device, and an ESB system such that information is transferred in an ESB system more flexibly. The method includes receiving service information, sent by a console, of a to-be-deployed first service, where the service information includes a definition of the first service and a service identifier of the first service, generating a first service instance according to the definition of the first service, where the first service instance is a service instance, deployed on a first deployment node, in service instances of the first service, and sending first address information to service instances in an enterprise service bus ESB system except the first service instance using the first service instance such that a second deployment node invokes the first service instance according to the first address information using a second service instance.

Abstract: The present invention provides a system and a method for managing an expanded service characteristic packet, which solve the problem that the WAB of a Web layer lacks the capabilities of modularization. The method comprises: obtaining a basic characteristic packet identifier and a resource request path according to a Web resource request, wherein, the resource request path is the path of a resource required to be obtained in a service characteristic packet; obtaining existing basic characteristic packets and service characteristic packets, and screening out the service characteristic packet having a mounting identifier identical to the basic characteristic packet identifier obtained from the Web resource request; storing the mounting identifier in the service characteristic packet for designating a basic characteristic packet to be mounted; and loading the screened service characteristic packet according to the resource request path, and returning the obtained resource.
