Abstract:
A method of controlling residual coding for decoding or encoding of a video sequence, is performed by at least one processor and includes determining whether to replace a transform type of Multiple Transform Selection (MTS) by using Identity transform (IDT), based on whether either one or both of a block height and a block width meet a predetermined condition; and based on either one or both of the block height and the block width meeting the predetermined condition, replacing the transform type of MTS by using the IDT and keeping a syntax of the MTS unchanged, and the IDT is a linear transform process using an NxN transform core in which each coefficient is non-zero along a diagonal position, and wherein N is an integer.
Abstract:
A method and apparatus for encoding or decoding a video sequence includes encoding or decoding the video sequence using a 4:4:4 chroma format, or encoding or decoding the video sequence using a 4:2:2 chroma format, wherein when encoding or decoding the video sequence using the 4:4:4 chroma format, copying an affine motion vector of one 4x4 chroma block using an operation other than an averaging operation, and when encoding or decoding the video sequence using the 4:2:2 chroma format, associating each 4x4 chroma block with two 4x4 co-located chroma blocks such that an affine motion vector of one 4x4 chroma block is an average of the motion vectors of the two co-located chroma blocks.
Abstract:
A method for decoding a video sequence of a coded video stream, performed by at least one processor, using at least one color palette in a palette mode, each of the at least one color palette including at least one luma value or at least one chroma value, the method including determining whether a current tree structure is a dual tree structure where a luma color plane has a split tree structure that is different from a split tree structure of a chroma color plane; and decoding at least one image of the video sequence using one or more color palettes of the at least one color palette based on the determining whether the current tree structure is the dual tree structure.
Abstract:
A method and apparatus for generating a merge candidate list for encoding or decoding of a video sequence includes determining a first candidate block that includes a vertical position above a top edge of a current block, and that includes a horizontal position adjacent to a horizontal center of the current block. A second candidate block is determined that includes a horizontal position that is located to a left side of a left edge of the current block and a vertical position adjacent to a vertical center of the current block. The merge candidate list is generated using the first candidate block and the second candidate block to permit the encoding or the decoding of the video sequence.
Abstract:
A method of performing merge candidate list construction for video coding using at least one processor includes determining a plurality of potential merge candidates; selecting a first potential merge candidate from among the plurality of potential merge candidates; performing a redundancy check by checking the potential merge candidate against a merge candidate included in the merge candidate list; based on a result of the redundancy check, determining whether to insert the potential merge candidate into the merge candidate list; determining whether a redundancy check threshold is exceeded, wherein the redundancy check threshold relates to at least one from among a number of redundancy checks which have been performed, and a number of potential merge candidates which have been checked by the redundancy checks; and based on the redundancy check threshold being exceeded, determining not to perform additional redundancy checks during the merge candidate list construction.
Abstract:
Peptide antagonists of MDM2 and MDMX are disclosed. The peptide antagonists include antagonists of MDM2 or MDMX, as well as dual-specificity antagonists where the same peptide is an antagonist of both MDM2 and MDMX. The peptide antagonists have at least nanomolar binding affinity for MDM2 and/or MDMX, and in some cases picomolar binding affinity. The peptide antagonists can be used in methods based on blocking inhibition of p53 activity by MDM2 and/or MDMX. Such methods can be used in the treatment of diseases, such as cancer.
Abstract:
Methods and systems to support input output (10) communications may include an lO connector having a housing with surfaces defining a paddle card region, and a set of compressible contacts extending vertically through the housing into the paddle card region. In addition, an 10 interconnect can include a cable portion and at least one end portion coupled. to the cable portion. The end portion may include a paddle card having a circuit board with a set of contacts disposed on a bottom surface of the circuit board. The end portion can also include an asymmetric metal shell having a configuration that encloses at least a portion of the paddle card and exposes the set of contacts.
Abstract:
Methods, systems, devices, and computer program products are described for network scaling. In one example, candidate cells may be selected and ranked. For an initial assessment, the selected cells may operate at a significantly reduced power, and the network performance may be evaluated. Based on the results, only a subset of the candidate cells may be switched off. The whole process may be repeated until all the candidate cells are evaluated. Network downscaling may be done at a site level, a sector level, or a hybrid (site level first, and then additional downscaling by sector level).

Abstract:
A replaceable spiral wound membrane element can be inserted and removed from its housing or pressure vessel in one piece for servicing or replacement. The replaceable wound membrane element preferably includes a concentrate pipe (12) connected to spacers (34) and membranes (16) that are wound around the concentrate pipe (10) to form a spiral membrane element. After the replaceable membrane element is placed inside its housing, its dilute spacers are filled with ion exchange resin and the housing is sealed to form an electrodeionization (EDI) module.
