Abstract: The present invention relates to novel linkers containing a 2,3-disubstituted succinic group, or 2-monosubstituted, or 2,3-disubstituted fumaric or maleic (trans (E)- or cis (Z)-butenedioic), or acetylenedicarboxyl group for conjugation of a cytotoxic agent, and/or one or more different functional molecules per linker to a cell-binding molecule, through bridge linking pairs of thiols on the cell-binding molecule specifically. The invention also relates to methods of making such linkers, and of using such linkers in making homogeneous conjugates, as well as of application of the conjugates in treatment of cancers, infections and autoimmune disorders.

Abstract: The present invention relates to a layered semi-parallel LDPC decoder system having a single permutation network, and belongs to the field of decoder hardware design. The system comprises a layered decoding architecture of the single permutation network, a layered semi-parallel decoding architecture of the single permutation network, a pipeline design for layered semi-parallel decoding and a hardware framework of a layered semi-parallel LDPC decoder. The present invention removes a permutation network module between a check node and a variable node by modifying the cyclic shift value of each information block transferred from the variable node to the check node, i.e., the cyclic shift operation of the decoder can be completed through the single permutation network so as to reduce hardware resources of the decoder. A semi-parallel decoding structure is adopted, and meanwhile, a pipeline is added between half layers.

Abstract: The present application discloses an information push method and apparatus, a device, and a storage medium, which relate to the field of intelligent search technology. A specific implementation of the method in the present application lies in: acquiring a user feature and an item feature, where both the user feature and the item feature include click through rate information; determining a degree of similarity between the user feature and the item feature; determining, according to the degree of similarity, item information that is recalled; and pushing the item information to a user terminal. According to the present application, item information having a high click through rate may be acquired through a one-channel recall approach, so that information push efficiency is improved and the pushed item information better conforms to user needs.
