Abstract: The present disclosure provides a formulated pectin composition for lowering food glycemic index (GI) value. The formulated pectin composition comprises low-ester pectin and metal salt of bivalent/trivalent cation, with or without soluble polysaccharides. The formulated pectin composition may comprise the components: pectin and metal salt of bivalent or trivalent cation, in the following weight percentages: the pectin 94.3-97.1% and the metal salt of bivalent or trivalent cation 2.9-5.7%.

Abstract: The present disclosure provides a formulated pectin for reducing food GI, comprising low-ester pectin and metal salt of bivalent/trivalent cation, with or without soluble polysaccharides. The components of the formulated pectin, according to the present disclosure, are synergistic with each other and can be added to a carbohydrate-based medium and high GI food to achieve the effect of lowering the GI value of the food through a unique physical reaction in the gastrointestinal tract, thereby obtaining a corresponding low GI food. In preparing the low GI food containing said formulated pectin of the present disclosure, only a small amount of said formulated pectin is required to be added to the raw material, and then customarily cooked or baked, allowing little effect on the processing, and almost no impact on the food taste and status. The food can be effective over a wide range of cooking temperatures.

Abstract: Disclosed is a live broadcast system for assisting remote home rehabilitation. The system includes: an anchor client, a Bluetooth heart rate component, a user client, and a movement video library. The anchor client is configured to display information of a live class, create the live class, start the live class, cancel the live class, interact with a user during a live broadcast, and monitor exercise status of the user and an overview of an exercise status of all users participating in the live class after the live broadcast. The user client is configured to display information of a live class, make an appointment to participate in the live class, enter the live class, provide real-time visual feedback on an exercise mode of a user, display a real-time heart rate of the user, cancel the live class, interact with an anchor during a live broadcast, and display after-class information.

Abstract: The present disclosure relates to an apparatus and method for automatically adjusting an exercise prescription based on an exercise heart rate. The apparatus includes: a heart rate detection device, configured to detect a resting heart rate and a user's real-time exercise heart rate; an exercise movement library, configured to store various exercise instruction video and audio, and provide movement guidance for the user; an exercise guidance module, configured to retrieve and display movement video and audio from the exercise movement library to the user; and a central processing unit (CPU), configured to acquire the resting heart rate and the user's real-time exercise heart rate, calculate an effective exercise target heart rate range based on the resting heart rate, determine whether the real-time exercise heart rate falls within the effective exercise target heart rate range.

Abstract: The present disclosure relates to an apparatus for differentially calculating target heart rates of different users, including: a user client, including a health data acquisition module, a medication data acquisition module, and a user-side target heart rate display module; a heart rate detection device, worn on a user and including an exercise test data acquisition module; a server, including a data input module and a core processor; and a doctor client, including a data sending module and a doctor-side target heart rate display module.

Abstract: A honeycomb-shaped fuel assembly cooled by liquid chloride salt adopts a honeycomb-shaped structure. A fuel coolant is a mixture of liquid three-phase chloride salt NaCl—KCl—MgCl2. Fuel is U3Si2 with an enrichment of 19.75% or 16.0%. The fuel assembly includes: fuel coolant channel pipelines which vertically penetrate and laterally merge, a fuel coolant contained in the fuel coolant channel pipelines, a fuel zone, upper and lower endcap, a top gas plenum, and upper and lower endcap. A reflector assembly adopts a honeycomb-shaped structure, including: reflector coolant pipes which are vertically penetrating; a reflector coolant contained in the reflector coolant pipes; a titanium reflector; and upper and lower endcaps. A control assembly and a safety assembly adopt a rod bundle structure using B4C with a natural enrichment of 10B as absorbers.

Abstract: A mechanical motor-driven friction brake device for a rail vehicle consists of a torque motor, an electromagnetic brake (5), a screw nut transmission mechanism, and a brake friction pair (6), the torque motor and a screw (4) being coaxially mounted, the screw (4) being in non-self-locking threaded connection with a nut (3), and one end of the nut (3) being connected to the brake friction pair (6); the device drives, by means of the torque motor, the screw (4) to rotate so as to drive the nut (3) to perform linear motion and outputs a pressure or a pulling force to the brake friction pair (6), so as to brake or release the rail vehicle; in addition, this device can lock the screw by means of the electromagnetic brake (5), realizing the function of parking brake.
