Abstract: A computerized method determines similarities between a first image and a second image. The first image is converted into a first grayscale image, and the second image is converted into a second grayscale image, where a number of pixels of the second image is not less than a number of pixels of the first image. Each pixel of the first grayscale image is matched with a pixel of the second grayscale image to create a pixel pair sequence. A similarity value indicating the similarities between the first image and the second image is calculated according to the grayscale value of each pixel in the pixel pair sequence S.

Abstract: The invention discloses a packing bag of a liquid crystal display (LCD) and a packing method thereof. The packaging bag of a liquid crystal display includes a bag body and an opening. A sealing structure which can be repeatedly unsealed/sealed is disposed at the opening. The invention adopts the sealing structure at the opening of the packing bag to conveniently seal/unseal the opening of the packing bag. Therefore, the packing bag can be circularly reused and decrease the cost. The packing bag is sealed by the sealing structure without folding of the packing bag to decrease material of the packing bag and further decrease the cost.

Abstract: Disclosed herein are techniques for computationally designing enzymes. These techniques can be used to design variations of naturally occurring enzymes, as well as new enzymes having no natural counterparts. The techniques are based on first identifying functional reactive sites required to promote the desired reaction. Then, hashing algorithms are used to identify potential protein backbone structures (i.e., scaffolds) capable of supporting the required functional sites. These techniques were used to design 32 different protein sequences that exhibited aldol reaction catalytic function, 31 of which are defined in the Sequence Listing. Details of these 31 different synthetic aldolases are provided, including descriptions of how such synthetic aldolases can be differentiated from naturally occurring aldolases.
