Deep neural networks tend to overfit to biased training data when there are noisy labels or imbalanced class distributions in the training set. Using reweighting strategies with appropriate sample weighting is a common method to address this issue. However, improper reweighting schemes will introduce additional overhead and bias to the network's learning process, it is difficult to solve overfitting problems in biased distribution networks using only reweighting methods. To address this problem, this paper proposed a method that combined label smoothing regularization, class margin regularization, and reweighting, and presented an EMN method based on adaptive reweighting and regularization, which consisted of a base network for classification and an ensemble meta-net for hyperparameter estimation. The method first obtained the sample loss through the base network, then used three meta-learners to estimate the hyperparameters of adaptive reweighting and regularization in an integrated manner based on the loss, and finally used the three hyperparameters to calculate the final ensemble meta-loss and update the base network, thereby improving its performance on biased distribution datasets. Experimental results demonstrate that EMN achieves higher accuracy on CIFAR and OCTMNIST datasets compared to other methods, and the effectiveness of diffe-rent strategies are demonstrated through policy correlation analysis.

Aim To explore the effect of Buyang Huanwu decoction on anti-atherosclerosis by regulating the phenotypic transformation of vascular smooth muscle cells and serum inflammatory response based on Wnt/β-catenin signaling pathway. Methods 50 ApoE-/- mice were randomly divided into model group, Buyang Huanwu decoction modified (low, medium and high dose) groups, and atorvastatin group, with 10 mice in each group; 10 C57BL/6J mice with the same genetic background were set as the control group. The mice of control group were fed with regular forages, while the mice of other five groups were fed with high-fat forages for 8 weeks for model replication. From the 9th week, they were continuously gavaged for 4 weeks. After 12 weeks, the mouse aortic roots were isolated and paraffin sections were prepared. Oil red O staining was used to observe the lipid content of aortic sinus. Immunohistochemical method was used to detect the expression level of bone bridge protein (OPN). Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and monocyte chemoattractant protein-1 (MCP-1) in serum. Western blot was used to detect the protein expressions of Wnt1, β-catenin and c-myc in mice aorta. RT-PCR was used to detect the expressions of Wnt1 and β-catenin gene. Results Buyang Huanwu decoction modified (low, medium and high dose) could reduce the lipid content and OPN expression in the aortic sinus of As model mice, reduce serum levels of IL-6 and TNF-α, IL-1β and MCP-1 in mice, and downregulate the expression of Wnt1 and β-catenin protein and gene. Conclusion Buyang Huanwu decoction modified exerts an anti-atherosclerosis effect by regulating inflammatory response, and some of the mechanisms may be related to inhibiting the activation of the Wnt/β-catenin signaling pathway.

In order to solve the problem that the transmission torque and service life of clutch was hard to meet the working demand of the air compressor in automobile air conditioning system, the friction and wear performance of the friction plate material of electromagnetic clutch was studied through experimental ways. Firstly, tribological wear tests were performed on B/Y-type friction-enhancing materials which commonly used on the friction plate, the friction coefficient and friction surface temperature were measured under different working parameters. Secondly, the tribological properties change patterns under different influencing factors were comparatively analyzed. Lastly, the post-wear morphology of the sample after running-in test was observed with scanning electron microscopy, and the primary wear mechanisms was analyzed in conjunction with the comparison of elementary composition. The results show that the speed, the loading force, and the initial roughness of the friction parts are proportional to the friction coefficient and the temperature rise of the friction surface. In addition, the friction coefficient of the two materials finally stabilizes in the range of 0.3～0.45. Among them, the surface microcracks and peeling of B-type materials are more serious, and the Fe content increases by 23.95% after running-in with No. 10 steel materials. Y-type materials have better frictional thermal stability and wear resistance, and the use of Y-type materials is more conducive to improving the transmission torque and service life of electromagnetic clutches.

Malicious face manipulation has a negative impact on social security and stability, and it is a very important issue to accurately detect video images after face tampering. In order to solve the problem of poor real-time performance of video manipulation detection model, this paper proposes a face manipulation video detection model based on ensemble learning dual-stream recurrent neural network, and introduces the voting mechanism in ensemble learning. The model first receives a small number of consecutive sequence frames, extracts spatial features through a convolutional neural network, and introduces central differential convolution to enhance tampering artifacts in the spatial domain. The model then differentiates consecutive sequence frames to enhance tampering artifacts in the temporal domain, while temporal feature extraction is performed through a convolutional neural network. Then, the model splices the dual-stream feature vectors in the spatial domain and the time domain, and performs feature extraction through a recurrent neural network. During the feature extraction process of the recurrent neural network, the frame-by-frame feature information is retained as the input of the subsequent auxiliary frame-level classifier, while the final output of the recurrent neural network is used as the input of the video-level discriminator. Finally, the model introduces the voting mechanism of the integrated model to integrate the outputs of multiple auxiliary frame-level discriminators and video-level discriminators, and introduces a weight hyperparameter γ to balance the importance of the auxiliary framelevel discriminator and video-level discriminator, helping the model to improve detection accuracy. On the FaceForensics++ dataset, the experimental results show that the proposed model improves the average accuracy by 0.4% and 1.0% compared with mainstream detection model. At the same time, the proposed model can only use fewer consecutive frames for manipulation detection, which improves the real-time performance of the model. [ABSTRACT FROM AUTHOR]

The protein, polysaccharide and DNA contents of supernatant, SMP, LB-EPS and TB-EPS of four groups of activated sludge with different salinity were determined. There are a lot of macromolecular proteins in the supernatant of mixed solution under high salt. The components in the mixed solution should be considered in the extraction of EPS from salty sludge. Comparing the five extraction methods of TB-EPS (centrifugal, ultrasonic, heating, formaldehyde and formaldehyde + NaOH), formaldehyde + NaOH method still has the highest total extraction amount in high salt environment. The 3D fluorescence spectra of TBEPS extracted by different extraction methods were analyzed by parallel factor technique. The results showed that formaldehyde and heating had two common components ( humic acid and protein-like), which provided two new extraction and analysis methods of EPS. [ABSTRACT FROM AUTHOR]

The number of patients with the combination of non-alcoholic fatty liver disease (NAFLD) and hepatocellular carcinoma (HCC) is gradually increasing. In recent years, the immunotherapy has become a new effective way to treat unresectable HCC. The clinical research revealed that the NAFLD could affect the efficacy of immunotherapy treating the HCC. But the mechanism is complicated. The major routes are CD8+ PD-1+ T cells increasing in NAFLD cause the deficiency in cell proliferation ability; Zn64 activates the anti-tumor immune response of the CSF1; PCSK9 downregulates the LDLR level to suppress the immune response of the CD8+ T cells in tumor microenvironment; loss of the immune response induces the liver damage. Researches had indicated that the combination of lenvatinib, PKCa inhibitor, PCSK9 protein inhibition, ferroptosis inducer, and HIF2a small molecule inhibitor can improve the efficacy of immune checkpoint inhibitors for NAFLD-associated hepatocellular carcinoma. This review focuses on the impact of NAFLD on tumor microenvironment and how the NAFLD affect the immune check-point inhibitor effect and to discover the exact mechanism. [ABSTRACT FROM AUTHOR]
