Abstract: Provided are an intra prediction method and apparatus, and a computer-readable storage medium. The method includes: acquiring a first reference sample set corresponding to the current processing block, wherein the first reference sample set includes at least one of a reference row adjacent to the current processing block and a reference column adjacent to the current processing block; selecting, based on a pre-set selection method, a second reference sample set from the first reference sample set, wherein the second reference sample set includes at least one reference sample in the reference row adjacent to the current processing block or the reference column adjacent to the current processing block; obtaining, based on the second reference sample set, a prediction value of the current processing block; and performing, based on the prediction value, intra prediction on the current processing block.

Abstract: Disclosed are a chair device and a star-shaped base (3) thereof, in particular capable of being used for office chairs, work chairs, stools or standing auxiliary devices, the star-shaped base comprising a center seat (4) and a plurality of extending arms (5) mounted on the center seat (4), wherein the extending arms (5) are used for the star-shaped base (3) to be placed on the ground, and at least one of the extending arms (5) is hinged to the center seat (4) and can rotate relative to the center seat (4). A chair seat of the chair device can rotate or swing, while parts mounted at an upper end of a chair column do not need to be modified, and particularly, a supporting structure, a chair support for the chair seat to be placed, and the chair seat itself do not need to be modified.

Abstract: The embodiments of the disclosure disclose a method for determining a prediction direction, a decoder and a computer storage medium. The method is implemented by a decoder. The method includes that: a Direct Mode (DM) in a chroma intra prediction mode of a block to be decoded is acquired (S101); and an index number of a prediction direction in a DM derived mode is determined based on an offset N and an index number M of a prediction direction in the DM to determine the DM derived mode (S102).

Abstract: Provided are a Candida tropicalis strain Am2525, with the preservation number thereof being CCTCC NO: M 2019419, and a method for producing long-chain dicarboxylic acids by means of fermenting the strain. The method for producing the long-chain dicarboxylic acids comprises preparing a seed solution by means of the Candida tropicalis strain Am2525 and producing the long-chain dicarboxylic acids via fermentation of the seed solution. Compared with the parent, the Candida tropicalis strain Am2525 has an enhanced resistance to the toxicity of a substrate decane, improves the productivity of long-chain dicarboxylic acids, reduces the cost of production, subsequent separation and purification are simple, and the fermentation production process is easy to implement on a large scale.
