Described are techniques in video coding and/or decoding that allow for selectively breaking prediction and/or in loop filtering across segment boundaries between different segments of a video picture. A high layer syntax element, such as a parameter set or a slice header, may contain one or more indications signalling to an encoder and/or decoder whether an associated prediction or loop filtering tool may be applied across the segment boundary. In response to such one or more indications, the encoder and/or decoder may then control the prediction or loop filtering tool accordingly.

The present invention relates generally to novel depsipeptides, to methods for the preparation of these novel depsipeptides, to pharmaceutical compositions comprising the novel depsipeptides; and to methods of using the novel depsipeptides to treat or inhibit various disorders.

Described is picture segmentation through columns and slices in video encoding and decoding. A video picture is divided into a plurality of columns, each column covering only a part of the video picture in a horizontal dimension. All coded tree blocks (“CTBs”) belonging to a slice may belong to one or more columns. The columns may be used to break the same or different prediction or in-loop filtering mechanisms of the video coding, and the CTB scan order used for encoding and/or decoding may be local to a column. Column widths may be indicated in a parameter set and/or may be adjusted at the slice level. At the decoder, column width may be parsed from the bitstream, and slice decoding may occur in one or more columns.

A species of Burkholderia sp with no known pathogenicity to vertebrates but with pesticidal activity (e.g., plants, insects, fungi, weeds and nematodes) is provided. Also provided are natural products derived from a culture of said species and methods of controlling pests using said natural products.

A benzothiazole meroterpenoid compound derived from deep sea fungi and a derivative thereof, and a preparation method therefor and the use thereof in the preparation of an anti-tumor drug are provided. The benzothiazole meroterpenoid compound is a compound as represented by formulas I to III or a salt thereof. The compound is isolated from a fermentation product of deep-sea-derived Penicillium allii-sativi and inhibits the transcriptional activity of an anti-tumor target RXRalpha by means of binding thereto so as to achieve a remarkable anti-tumor effect. The compound can be used for preparing, researching and developing anti-cancer drugs, and has good application prospects.
