Abstract: An aqueous fire extinguishing agent and a preparation method thereof are provided, which are used for making a throw-type fire extinguisher. The aqueous fire extinguishing agent is composed of two compositions of A and B. The composition A is a fortified water added with a flame retardant (e.g., one or more of ammonium chloride, diammonium hydrogen phosphate and ammonium polyphosphate), a wetting agent (e.g., alkyl polyglycoside) and a colloid (e.g., polyacrylamide solution). The composition B is a regulator. After the composition A and the composition B are mixed, a discharge rate/speed of fire extinguishing substances is increased, so that an escape passage/route can be opened up quickly.

Abstract: The invention belongs to the field of biological medicine, and relates to use of an IgG4 detection reagent, a subclass of immunoglobulin, in preparation of a colorectal cancer diagnosis or prognosis reagent/kit. According to the present invention, IgG4, a subclass of immunoglobulin, is highly expressed in colorectal cancer with great difference and credibility. Use of IgG4 as a colorectal cancer diagnostic biomarker has advantages of being strong in specificity and high in sensitivity, which is beneficial to improving the diagnosis and treatment level of colorectal cancer, and effectively prevents and treats colorectal cancer.

Abstract: Embodiments of this application provide a near-field wireless communication service processing method performed at a first computing device associated with a social networking application. While running a social networking application, the first computing device detects a near-field wireless communication signal broadcasted by a second computing device associated with a service provider account registered with the social networking application.

Abstract: Embodiments of this application provide a near-field wireless communication service processing method performed at a first computing device. While running a social networking application, the first computing device listens to a near-field wireless communication signal broadcasted by a second computing device. After detecting the near-field wireless communication signal broadcasted by the second computing device, first computing device processes the near-field wireless communication signal to obtain identification information associated with the second computing device. The first computing device sends the identification information associated with the second computing device to a remote server supporting the social networking application and obtains a preset service page corresponding to the identification information associated with the second computing device from the server, and displays the preset service page within the social networking application on the first computing device.

Abstract: Systems and methods are provided for data migration. For example, a data packet of a first platform is acquired; the data packet is parsed to obtain one or more data structure fields of the data packet; the data structure fields of the data packet are matched with a predetermined first field mapping table; in response to the data structure fields of the data packet being matched with the predetermined first field mapping table, the data packet is associated with a second platform based at least in part on one or more predetermined association rules; the data packet is converted based at least in part on the association of the data packet and the second platform; and the converted data packet is migrated to the second platform.
