Abstract: A method and device for storing high-concurrency data. The method comprises: receiving high-concurrency data sent from a plurality of clients (110); pushing the high-concurrency data into a primary data queue, and responding to a corresponding client (120); consuming the high-concurrency data in the primary data queue by using multithreading (130); fragmenting the high-concurrency data according to the number of local queues (140); pushing the fragmented high-concurrency data into the local queues (150); and consuming the high-concurrency data in the local queues and storing the high-concurrency data in a database (160). By means of data asynchronous storage, high-concurrency data is temporarily stored in the primary data queue and the local queues, thereby alleviating pressure on the database, avoiding the problem that the database crashed in the case of a high-concurrency storage, and improving the efficiency of storing high-concurrency data.

Abstract: A blower, including: a volute including air inlets and an air outlet; a wind wheel disposed in the volute; and air collectors. Each air collector includes a curved air guide. The air inlets are disposed at two sides of the wind wheel, respectively. The air collectors correspond to the air inlets. The curved air guide extends into the volute, and the inner diameter of the curved air guide decreases stepwise. The relationship between a minimum inner diameter D0 of the curved air guide and an inner diameter D1, an outer diameter D2 of the wind wheel fulfills the following formula: D1+?(D2?D1)?D0?D1+?(D2?D1). An exhaust fan that includes the blower is also provided.

Abstract: The present application relates to compositions comprising selenium (e.g., selenium enriched yeast) and methods of using the same to treat and inhibit obesity, diabetes and related conditions. In particular, the present application provides compositions comprising selenium enriched yeast (e.g., selenium enriched yeast comprising 2% or less inorganic selenium), and methods of using the same to enhance mitochondrial activity and function (e.g., in skeletal muscle and liver) in a subject (e.g., as a therapeutic and/or prophylactic treatment for diabetes, obesity and related conditions).

Abstract: The present application relates to compositions comprising selenium compounds, such as 5?-Methylselenoadenosine, Se-Adenosyl-L-homocysteine, Gamma-glutamyl-methylseleno-cysteine, a compound of Formula (I), Formula (II), or Formula (III), and combinations thereof, and methods of using the same for modulating glucose metabolism in a subject.

Abstract: The invention provides a radial ring rolling process for controlling strain distribution of a ring product. In the process, a ring blank is rolled by a main roll and a mandrel that are driven to rotate, while a gap between the main roll and the mandrel continuously decreases in the radial direction of the ring blank. The process includes (A) according to dimensions of the ring product and expected strain, a rolling ratio is firstly determined, dimensions of the ring blank is calculated based on the rolling ratio and the dimensions of the ring product; (B) a rotation speed curve of the mandrel is determined based on the rotation and the radial feeding speeds of the main roll; (C) the ring blank is rolled according to the rotation and radial feeding speeds of the main roll and the calculated rotation speed of mandrel in step (B).

Abstract: A swim training and buoyancy assist device for an anchoring device has a resilient element and a resilient tether. The anchoring device is located at a certain location beside a swimming pool. The resilient element has a proximal end and a distal end. The proximal end of the resilient element is connected to the anchoring device. The resilient tether has a proximal end and a distal end. The proximal end of the resilient tether is connected to the distal end of the resilient element. The distal end of the resilient tether is connected to a swimmer. When the swimmer is connected to the resilient element and the resilient tether, the swimmer can only move a short distance in a certain direction and is buoyed up at a certain depth in the water so that the swimmer, especially a beginner, can practice swimming in a small area without the fear of drowning.

Abstract: A swimming exerciser has a vertical support, an arm, a roller assembly, a resilient element, a belt, a resilient tether and a rope. The vertical support is mounted beside a swimming pool and has a pulley. The arm is hollow and is connect to and protrudes from the vertical support and has a distal end. The roller assembly is mounted moveably inside the arm. The resilient element is mounted inside the arm between the roller assembly the distal end of the arm. The belt is worn around a person's waist. The resilient tether is attached to the roller assembly and the belt and compensates for a swimmer's lack of movement through the water to hold the swimmer at a constant depth. The rope is connected to the roller assembly, reeved through the pulley and connected to the belt to hold a swimmer in a fixed position when swimming.
