This paper defines a pairing of two finite Hopf C^＊-algebras A and B, and investigates the interactions between them. If the pairing is non-degenerate, then the quantum double construction is given. This construction yields a new finite Hopf C^＊-algebra D（A, B）. The canonical embedding maps of A and B into the double are both isometric.

The effect of black plate on corrosion resistance of T5 tinplate was studied by glow discharge spectrograph, X-ray diffractometer （XRD）, stress tester, roughness tester and metallographic microscope. The result shows that black plate influences corrosion resistance of T5 tinplate intensely. It also indicates that the increase of content of manganese, phosphorus, silicon and aluminum in black plate would reduce the corrosion resistance of T5 tinplate and the increase of degree of crystal orientation on （200） crystal face, ｜X-Y｜ value （internal stress difference within two orientation）, roughness and exposure degree of iron grain after the same acid wash of black plate would enhance the corrosion resistance of T5 tinplate and the grain number of black plate has small effect on corrosion resistance of T5 tinplate.

Long-term multivariate time series forecasting is an important task in engineering applications. It helps grasp the future development trend of data in real-time, which is of great significance for a wide variety of fields. Due to the non-linear and unstable characteristics of multivariate time series, the existing methods encounter difficulties in analyzing complex high-dimensional data and capturing latent relationships between multivariates in time series, thus affecting the performance of long-term prediction. In this paper, we propose a novel time series forecasting model based on multilayer perceptron that combines spatio-temporal decomposition and doubly residual stacking, namely Spatio-Temporal Decomposition Neural Network (STDNet). We decompose the originally complex and unstable time series into two parts, temporal term and spatial term. We design temporal module based on auto-correlation mechanism to discover temporal dependencies at the sub-series level, and spatial module based on convolutional neural network and self-attention mechanism to integrate multivariate information from two dimensions, global and local, respectively. Then we integrate the results obtained from the different modules to get the final forecast. Extensive experiments on four real-world datasets show that STDNet significantly outperforms other state-of-the-art methods, which provides an effective solution for long-term time series forecasting.

Objective To investigate the mechanism of immune hyporesponsiveness induced by donor-antigen- unloaded recipient-derived immature dendritic cell （imDC） of liver grafts in rats. Methods Forty Sprague-Dawley rats （donor） and forty male Wistar rats （recipient） were randomly divided into 4 groups： control, cyclosporine A （CsA）, mature DC （mDC）, and imDC groups respectively, with 10 donor rats and 10 recipient rats in each group. Recipient rats in CsA group were treated with 10 mg-kg-~＇d-I CsA starting day 2 after the transplantation. Recipients in the mDC or imDC groups were given Wistar rat derived mDCs （1 × 10^6/rat） or imDCs （1 × 10^6/rat） via dorsal vein of the penis respectively 1 day before the transplantation. In each group, 5 recipients were kept for determination of survival time and the other 5 rats were executed at day 10 after transplantation. Blood samples were collected for the measurement of serum alanine aminotransferase （ALT）, total bilirubin （TBIL）, interleukin 2 （IL-2）, interferon gamma （IFN-γ）, IL-4, and IL-10 levels. liver tissue was harvested for HE staining and acute rejection evaluation. Expression levels of Fas-L/Fas in the grafts were detected by immunohistochemical staining; andWestern blot was used to detect the expression level of Scurfm. Results The survival time of CsA and imDC groups was significantly longer than that of control and mDC groups （all P〈0.05）. The levels of serum ALT and TBIL in the control group （2072.20±217.93 IU/L and 147.42±22.02pmol/L） and mDC group （2117.00±285.13 IU/L and 141.58±20.82 pmol/L） were significantly higher than those in the CsA group （59.68±13.48 IU/L and 15.40±2.13 pmol/L） or imDC group （50.80±9.63 IU/L and 14.44±3.49 pmol/L）（all P〈0.05）. In the CsA and imDC groups, the levels of IL-2 （22.52±3.75 pg/mL and 22.12±3.90 pg/mL） and IFN-γ （309.20±25.19 pg/mL and 321.00±21.64 pg/mL） were significantly lower, but the levels of IL-4 （297.60±25.07 pg/mL and 277.00±22.47 pg/mL） and IL-10 （1226.00±140.49 pg/mL an
