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: The present disclosure relates to a method and system for generating an exercise prescription based on multi-label screening and difficulty classification. The method includes: obtaining movement data from a database; classifying the movement data according to different effects of different exercises on an cardiopulmonary function; obtaining results of an exercise test of a patient; determining an exercise intensity of the patient according to the results of the exercise test; matching the exercise intensity with the classified movement data to obtain a movement data level corresponding to the exercise intensity; and generating a corresponding exercise prescription according to the movement data level. The method can automatically generate the corresponding exercise prescription according to different conditions of patients.

Abstract: A space-saving locking device for a server cabinet which does not present sharp edges to a user during handling locks a first housing to a second housing and includes first and second locking members. The first locking member includes a clamping portion with one end defining a latching slot, the second locking member includes a locking portion matching the latching slot. When the first locking member is operated, the locking portion is latched to the latching slot, and the first locking member is locked to the second member. When the latching slot is detached from the latching portion in a predetermined direction, the first locking member and the second locking member are unlocked.

Abstract: A frame structure includes a first frame, a rail, a handle, a buckle, a second frame, and buffer members. The first frame includes a bottom plate and side plates. The bottom plate and the side plates define an accommodation space. The rail is located on each of the side plates. One end of the handle is movably disposed on the rails. The buckle is located on the first frame and detachably fastened with the handle. The second frame is movably received in the accommodation space. One end of each buffer member is fixed to a bottom surface of the second frame, and another end resists the bottom plate. The handle is coupled to the second frame. When the handle is separated from the buckle, the handle is pushed or pulled to remove the second frame from the accommodation space or press the second frame into the accommodation space.

Abstract: A space-saving locking structure without sharp edges for a server cabinet can lock a first housing to a second housing and includes first and second locking members. The first locking member includes a locking portion with a tail portion, the second locking member includes a blocking portion. The blocking portion has a rounded surface such that when the first housing is pressed along a first direction, the first housing approaches and closes with the second housing, the tail portion being set against a top of the blocking portion. When the first housing is further pushed in a second direction, the tail portion slides along the rounded surface of the blocking portion until the tail portion abuts against the blocking portion to lock the first housing to the second housing.
