Abstract: A display panel is provided. The display panel includes a first substrate, a second substrate, and a liquid crystal layer. The liquid crystal layer includes multiple liquid crystal molecules. The display panel includes multiple primary spacer assemblies, and each of the multiple the primary spacer assemblies includes a first primary spacer, a second primary spacer, and a piezoelectric element. The first primary spacer is adjacent to the second primary spacer, and two opposite ends of the piezoelectric element are respectively connected to the first primary spacer and the second primary spacer.

Abstract: A method for determining a compensation value for a local display region, a screen display method, and a terminal device are disclosed. The method for determining a compensation value includes turning on the screen to be compensated, wherein the screen to be compensated includes an aperture region and a non-aperture region; obtaining a first display data of the aperture region and a second display data of the non-aperture region when the screen to be compensated is turned on; determining display ratio between the aperture region and the non-aperture region, based on the first display data and the second display data; and calculating a compensation value for performing display compensation on the aperture region based on the display ratio.

Abstract: A cooking device includes: a box body provided with a buckle; a door body rotatably connected to the box body, and wherein the door body is provided with a door hook that is snap-fitted with the buckle, the door hook is movable relative to the door body, and has a first position and a second position, wherein when the door hook is snap-fitted with the buckle, the door hook is in the first position; and a switch assembly arranged on the box body and including a first button, a second button, and a blocking member. The blocking member is capable of being moved relative to the first button and/or the second button, and has a blocking position and an avoiding position. The first button is configured to drive the blocking member to move from the blocking position to the avoiding position.

Abstract: Compositions relating to a combination of two types of separation matrix; and to variant host cells which contain at least one essential host protein that is fused to an affinity binding tag or has been mutated to replace at least two of a plurality of histidines or basic amino acids are provided. Methods are also provided that relate to isolating a recombinant protein from a lysate.

Abstract: Methods and compositions are provided for producing membrane proteins or toxic proteins from recombinant DNA introduced into a prokaryotic host cell by targeting the expressed proteins to the envelope of the host cell. The methods and compositions utilize a protein vehicle fused to a protein of interest. The fusion protein may contain one or more protease cleavage sites to separate the protein of interest from the protein vehicle either in vivo or in vitro. The protein vehicle is characterized by a membrane-tar peptide and a trans-membrane segment separated by a cytoplasmic amino acid sequence that includes a cytoplasmic affinity-binding domain.

Abstract: Ligase detection reaction is utilized to distinguish minority template in the presence of an excess of normal template with a thermostable ligase. This process can be carried out with a mutant ligase, thermostable ligase, or a modified oligonucleotide probe. This procedure is particularly useful for the detection of cancer-associated mutations. It has the advantage of providing a quantitative measure of the amount or ratio of minority template.
