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: A saponin nano micelle, preparing method, application and pharmaceutical composition thereof is disclosed in the present invention. The saponin nano micelle comprises one or more of saponins represented by formula 1, in which, R1 and R2 are independently —H or a hydrophilic group, R3 is —H or —OH, R4 is a lipophilic group. The preparing method of the saponin nano micelle is that mixing the saponin with an organic solvent which can dissolve saponin, and then removing the organic solvent. The saponin micelle acts as a convey medium of the drug ingredients, and can replace conventional drug carriers such as pharmaceutical solubilizers or polymeric micelle, which has high safety and great significance. The pharmaceutical ingredients can prolong circulation time and biological half-life of drug in the blood, and increase the accumulation of drug in lesions, and reduce adverse reactions.

Abstract: Disclosed herein are various techniques for improving global path optimization in a system that uses camera path for three-dimensional reconstruction. A subset of frames of data for the global path, the key frames, may be used to reduce the computational complexity of the optimization, while preserving full three-dimensional detail in the optimized model by relating other measurements to the optimized key frame path.

Abstract: The present invention relates to backsheets containing formulated thermoplastic polyolefin (TPO) which may be used with photovoltaic modules. More specifically, the backsheets of the present invention have a first exterior layer that comprises TPO and a polyamide, such that a residual fusion heat after lamination of that layer is at least 40 J/g. Using such a layer, sufficient bonding to the encapsulant of a photovoltaic module can be achieved, while maintaining high heat resistance, having low distortion at high operating temperatures, and having relatively low high water vapor transmission rate. The present invention also relates to photovoltaic modules containing the backsheets of the present invention, as well as to methods for making the backsheets of the present invention.
