Truth discovery aims to resolve conflicts among multiple sources and find the truth. Conventional methods for truth discovery mainly investigate the mutual effect between the reliability of sources and the credibility of statements. These methods use real numbers, which have a lower representation capability than vectors to represent the reliability. In addition, neural networks have not been used for truth discovery. In this work, we propose memory-network-based models to address truth discovery. Our proposed models use feedforward and feedback memory networks to learn the representation of the credibility of statements. Specifically, our models adopt a memory mechanism to learn the reliability of sources for truth prediction. The proposed models use categorical and continuous data during model learning by automatically assigning different weights to the loss function on the basis of their own effects. Experimental results show that our proposed models outperform state-of-the-art methods for truth discovery.

Objective: To clarify the specific mechanisms of action of raw Phellodendron chinense Schneid. (RPC) and saltwater-processed PC (SPC) in the treatment of rats with a kidney-yin deficiency pattern (KYDP). Methods: Healthy rats were administered hydrocortisone to establish a KYDP model. The rats were divided into seven groups: blank control, model, positive control (Liuwei Dihuang pills), high-dose RPC, low-dose RPC, high-dose SPC, and low-dose SPC. Enzyme-linked immunosorbent assay was used to measure the levels of cAMP, cGMP, TRH, TSH, T3, T4, IFN-γ, TNF-α, and testosterone in the serum and the levels of Na+-K+-ATPase and Ca2+-Mg2+-ATPase in the liver. TRH mRNA expression in the rat hypothalamus was measured using RT-PCR. THRα1+2 protein expression in the hypothalamus of rats was measured using Western blot. Immunohistochemistry was performed to determine the expression levels of FAS, FasL, and TSHR. Flow cytometry was used to determine CD4+ and CD8+ T lymphocyte levels. Illumina MiSeq sequencing technology was used to evaluate the diversity of intestinal flora in KYDP rats. Results: The cAMP/cGMP ratio was significantly higher in the model group than in the blank control group (P = .048). Compared with the model group, after administration, the levels of the above-mentioned serum and liver indexes decreased, except that of testosterone. The CD4+/CD8+ ratio also decreased. Compared with the RPC group, the levels of T3, IFN-γ, FAS, FasL, and TSHR in the SPC group decreased whereas that of testosterone increased. Additionally, immune function and intestinal flora diversity improved in the SPC group. SPC proved to be more effective in improving liver energy metabolism in KYDP rats than RPC. Conclusion: SPC had a better therapeutic effect on KYDP than RPC. The underlying mechanism of action may be related to improvements in liver energy metabolism, immune function, and intestinal flora diversity. © 2024 B

涡流空气分级机分级粒径主要受转笼转速与入口风速匹配关系的影响。入口风速一定时,转笼转速越高,分级粒径越小,但这会造成流场速度分布不均匀,而降低分级精度。利用Fluent软件对具有直叶片转笼结构的涡流空气分级机进行建模和数值模拟,分析转笼内流场特性,针对其流场不均匀及转笼入口冲角大等现象,对转笼叶片的形状及安装角进行改进,提出一种圆弧形叶片转笼的设计方法。通过数值模拟及物料试验对改进结果进行验证,数值模拟结果表明:圆弧形叶片转笼入口冲角减小,流道内流场更加均匀,分级粒径减小。碳酸钙分级试验结果与数值模拟结果吻合:设计工况即入口风速为12 m/s,转笼转速为1 200 r/min时,采用设计的圆弧形叶片转笼在保持分级精度不变的情况下,分级粒径减小了11.5%。
