Abstract: The present invention proposes a dynamic resources allocation method and system for guaranteeing tail latency SLO of latency-sensitive applications. A plurality of request queues is created in a storage server node of a distributed storage system with different types of requests located in different queues, and thread groups are allocated to the request queues according to logical thread resources of the service node and target tail latency requirements, and thread resources are dynamically allocated in real time, and the thread group of each request queue is bound to physical CPU resources of the storage server node. The client sends an application's requests to the storage server node; the storage server node stores the request in a request queue corresponding to its type, uses the thread group allocated for the current queue to process the application's requests, and sends responses to the client.

Abstract: A fly ash-based fire-prevention and extinguishing material with carbon dioxide mineralized and stored, and a preparation method thereof are provided. The preparation method includes: separately weighing 100 parts to 120 parts of water, 1 part to 3 parts of a solid strong alkali, and 20 parts to 40 parts of a fly ash as raw materials, pouring the raw materials into a reactor successively to obtain a resulting mixture, and stirring the resulting mixture at a high rotational speed; adding 10 parts to 20 parts of a solubilizing agent to the reactor, sealing the reactor, introducing carbon dioxide to the reactor at room temperature to maintain a carbon dioxide pressure to obtain a resulting slurry, and stirring the resulting slurry at a high rotational speed; and further introducing carbon dioxide into the reactor to increase the carbon dioxide pressure, and stirring the resulting slurry at a low rotational speed.

Abstract: Disclosed is a new medicinal use of anionic clay, and particularly to a use of anionic clay in preparing a lead-removing medicine. The described medicinal use of the anionic clay is capable of effectively preventing and treating lead poisoning and excessive lead, has significant lead-removing effects and little side effects, and has positive clinical significance.

Abstract: A method and apparatus of determining an elastic modulus of a material having a Poisson's ratio v by a Berkovich indenter having an elastic modulus E; a Poisson's ratio v, and a cross sectional area A(h) as a function of depth are provided. The method and apparatus model the Berkovich indenter with a conical shape and a spherical cap.

Abstract: Errors in current methods of determining elastic modulus through depth-sensing indentation may be resulted from three major factors: 1. error in estimating the projected contact area A(hc) by indirect means such as from the unloading curve, especially in the cases where “piling-up” occurs; 2. reliance on the use of the initial unloading slope Su, which in some cases is not easily determined reliably; and 3. insufficient consideration on the influences due to indenter bluntness in some important models based on numerical treatments. This invention provides a new method of determining elastic modulus of an indented material, which overcomes the above deficiencies. The maximum load and the total displacement of the indenter (to give a nominal hardness defined in this invention), elastic work and total work are measured.
