Abstract: An electronic device is provided, including a housing, a screen, a deformation drive part, and a camera. The screen and the housing form an inner cavity in which the camera and the deformation drive part are disposed. The deformation drive part drives a second area located at an edge of the screen to switch between a flattened state and a curved state through deformation. When the second area is in the flattened state, the second area is a flat second plane area, and the second plane area is located in the same plane as a first plane area of a first area of the screen. A light-transmitting area is disposed in the second area. In the case that the second area is in the flattened state, ambient light passing through the light-transmitting area is projected onto the camera.

Abstract: The present disclosure belongs to the field of livestock molecular biotechnology, and provides kits and methods for pedigree division and paternity testing of domestic pigs. The kits and methods specifically select 14 SSR loci of domestic pigs, especially Anqing six-end-white pigs, and synthesize primers for corresponding loci. Through capillary electrophoresis detection of the ear tissue DNA of 98 Anqing six-end-white pigs, the count of effective alleles, heterozygosity, polymorphism information content, and genetic distance, and exclusion probability at each locus are calculated, the pedigree division of domestic pigs, especially Anqing six-end-white pigs, and paternity testing are conducted. The cumulative exclusion probability of 14 microsatellite loci is 99%.

Abstract: The present invention relates to a low-sugar or sugar-free type pectin soft candy and a preparation method thereof. The soft candy comprises sugar alcohol, glycerin and pectin, wherein the sugar alcohol comprises maltitol, a soluble sugar alcohol selected from erythritol, isomalt, xylitol, lactitol and mannitol, as well as sorbitol, which is characterized in that the weight ratio of the maltitol, the soluble sugar alcohol and the sorbitol is 1:(0.10-0.65):(0.03-0.26), and the weight ratio of the maltitol to the glycerol is 1:(0.04-0.52).

Abstract: An electronic device includes a housing, a display screen and a deformation driving component. The second region of the display screen is connected to the first region of the display screen which is a first plane region. The deformation driving component is connected to an inner side of the second region, and deforms to drive the second region to switch between a flattened state and a bent state. The electronic device further includes a support mechanism which includes a flat plate support body and a motion driving component; in a case that the flat plate support body is in the support state, the flat plate support body is supported on an inner side of the deformation driving component; and in a case that the flat plate support body is in the avoidance state, the flat plate support body avoids the second region that is in the bent state.
