Abstract: A direct current circuit breaker handcart and a direct current switch apparatus are provided. In the direct current circuit breaker handcart, the current carrying element is located on the support surface, and includes a main circuit breaker and an auxiliary circuit breaker electrically connected with each other; the commutation element is located on the support surface, is electrically connected with the current carrying element, and includes a commutation capacitor, a commutation inductor, a commutation switch assembly, and a commutation capacitor charger electrically connected with each other; the repulsive assembly is configured to control opening and breaking off of the main circuit breaker; the energy absorbing element is located on the support surface, and is electrically connected with the current carrying element and the commutation element, respectively.

Abstract: A server system receives a group operation request transmitted by a client. The group operation request is generated by the client in response to a trigger operation of a target group chat function, and includes a target identity and a target group chat function identifier. The server system determines a target group chat function use permission corresponding to the target identity. In accordance with a determination, based on the target group chat function use permission and the target group chat function identifier, that a user corresponding to the target identity has a permission to use the target group chat function, the server system transmits group operation result information to the client.

Abstract: An desk lamp includes a control main board, an alarm clock module and a light-emitting element. The alarm clock module is electrically connected to the control main board, and the alarm clock module at least includes two alarm clock modes. The light-emitting element is electrically connected to the control main board. The desk lamp can not only be used as a lighting device for emitting lighting rays, but also provide an alarm clock function. A user can set different alarm clock modes and can set two or more alarm clocks at different time according to an actual need.

Abstract: The present invention relates to a novel antibody and antibody fragment that specifically binds to TNFR2 and to a composition comprising said antibody or antibody fragment. In addition, the present invention relates to a nucleic acid encoding the antibody or an antibody fragment thereof and a host cell comprising the same, and to a related use thereof. Besides, the present invention relates to the use of the antibody and antibody fragment for treatment and diagnosis.

Abstract: A joint detection method for lymphangioleio-myomatosis and a use thereof is provided. The method includes the following steps: performing Target Sequencing based Hybridization capture: a Panel is designed for the whole coding regions of TSC1 and TSC2 genes highly related to LAM and mutation genes closely related to solid tumors to construct a gDNA library, and sequencing is performed on a machine after a hybrid capture; sorting: the above sequencing data are processed and analyzed by bioinformatics; performing a supplementary detection by CMA if the TSC1 and TSC2 genes are detected to be negative; performing a supplementary detection by MLPA if a one-hit locus is detected; and performing a supplementary detection by Sanger method if a locus is detected to be a undefined locus derived from either a somatic mutation or a germline mutation. This method improves the positive mutation detection rate of LAM patients.

Abstract: Methods of coating contacts to have a specific color. The color can be selected to match a color of a portion of a device enclosure for an electronic device housing the contacts. Examples can instead provide methods of coating contacts to have a color to contrast with a color of a portion of the device enclosure. These methods can provide electrical contacts having a low contact resistance and good corrosion and scratch resistance.
