Abstract: A method for quantitatively analyzing the reservoir formation of an ultra-deep evaporite-dolomite paragenesis system is performed as follows. A typical drilling core containing the evaporite-dolomite paragenesis system and a field section are observed. The logging data is subjected to single-factor analysis to determine the planar distribution regularity of the ultra-deep evaporite and the dolomite, and the analysis of sedimentary combination pattern and development evolution regularity is performed. The diagenetic system is determined, and the reservoir formation of the evaporite-dolomite paragenesis system is analyzed. Based on the above technical solutions, the property, the evolution path and the reservoir formation of sedimentation-diagenesis fluids in the evaporite-dolomite paragenesis system can be clarified.

Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. Processing circuitry decodes prediction information of a block from a coded video bitstream. The prediction information is indicative of a matrix based intra prediction for the block. The processing circuitry determines entries of a vector based on neighboring samples of the block.

Then, the processing circuitry multiplies, using the first multiplication tool, the entries of the vector in the reduced bit form with entries of a matrix to calculate a subset of prediction samples of the block, and determines other prediction samples of the block based on the subset.

Abstract: Technology is disclosed herein for detecting leaky word lines in a non-volatile storage system. The exact leaky word line may be located very rapidly using a divide and conquer approach. First a determination may be made whether at least one word line in a group such as any of the word lines in a block is leaky. This initial determination can be made very quickly. If no word line in the group is leaky, the search can end. However, responsive to a determination that at least one word line in the group is leaky, a divide and conquer search may be performed in which the group of the word lines is repeatedly divided into smaller sub-groups with selected smaller sub-groups tested for a short circuit until the leaky word line is located.
