Abstract: Embodiments of this application provide a function cache method and apparatus. The method includes: A primary controller sends first indication information to a first sub-controller in a plurality of sub-controllers, where the first indication information is used to determine a cache policy for an instance on a first computing node in a cluster; the first sub-controller performs instance caching on the instance on the first computing node based on the first indication information; the primary controller sends second indication information to a second sub-controller in the plurality of sub-controllers, where the second indication information is used to determine a cache policy for an instance on a second computing node in the cluster; and the second sub-controller performs instance caching on the instance on the second computing node based on the second indication information.

Abstract: Disclosed is a sex identification specific DNA sequence and a sex identification method of Chinese mitten crab Eriocheir sinensis. The sex identification specific DNA sequence is showed as SEQ ID NO:1. The sex identification method includes following steps: S1, extracting genomic DNA of Chinese mitten crab Eriocheir sinensis; S2, PCR amplification using the genomic DNA as template; an upstream primer for PCR amplification is as shown in SEQ ID No: 2 and a downstream primer is as shown in SEQ ID No: 3; S3, examining amplified products by agarose electrophoresis, and those with specific amplified bands are females, otherwise they are males. The method has high identification accuracy, is simple and easy to operate, and is suitable for sex identification of Chinese mitten crab Eriocheir sinensis at embryonic and larval stages.

Abstract: Disclosed is a method for preparing a heterogeneous metal composite structure for medical implantation, including the steps of: step 1, preparing titanium alloy powder into a porous skeleton according to different printing strategies; step 2, filling magnesium after being melted into pores of the porous skeleton; and step 3, cooling a titanium-magnesium interpenetrating phase composite structure prepared in step 2 to room temperature, and covering a surface of the titanium-magnesium interpenetrating phase composite structure with a hydroxyapatite coating. In the present disclosure, a porous lattice dot-array structure of titanium alloy is used as a skeleton, and the skeleton pore is filled by pressureless infiltration of magnesium or hot isostatic pressure.

Abstract: A blowing-suction machine includes a casing, a suction duct arranged at the front portion of the casing. It further includes a motor and a shredder mechanism that are arranged in the casing in order from rear to front. The front end of the shredder mechanism is connected to the rear end of the suction duct. The shredder mechanism includes blades and a cutting assembly that are arranged in order from rear to front. The blades are arranged on an output shaft of the motor. The cutting assembly is arranged at a rear end of the suction duct for shredding fallen leaves. The cutter cooperates with the secondary cutter such that fallen leaves and rigid trashes can be effectively shredded by the blowing-suction machine. Fallen leaves can be effectively separated from air via the collecting cartridge and the filtering unit, such that the amount of the collected leaves is effectively increased.

Abstract: The present application relates to a method, a system, and intelligent terminal for controlling the operating range of a walking device. The present application resolves the time-consuming and laborious problem caused by installing an electronic fence or performing an artificial wiring before using a mower. In the present application, an electronic fence is not needed, the time and cost of manual installation is reduced and the use efficiency is improved.
