污水处理厂的智能化管理对于未来智慧城市的可持续发展至关重要,这项管理工作的核心之一在于对每日污水业务量的准确预测。从系统科学的角度而言,污水的产生是整个社会系统多种因素共同作用的结果。数据挖掘技术具有很强的抽象能力,能够用来构建实现污水处理厂智能化管理的预测方法。然而,现有的基于数据挖掘的方法只关注单一因素,如经济或气象因素,而忽略了它们的协同效应。针对这一挑战,本文提出了一种基于深度学习的污水厂智能化管理机制来预测污水业务量。将灰色关联算法(GRA)和门控递归单元网络(GRU)结合成预测模型(GRA-GRU)。利用GRA选择对污水业务量有显著影响的因素,利用GRU输出预测结果。本文进行了大量的实验来验证所提出的GRA-GRU模型的有效性。

The specificity of the double-stranded RNA(dsRNA) used in the RNA interference(RNAi) technique is crucial for the success of sequence-specific gene silencing. Currently, RNAi-mediated insect control is a trending research ***, the off-target effects of the dsRNA in RNAi are a major concern. In this study, the ds Hvβ’COPI(coat protein complex I, β’ subunit)-treated and untreated transcriptomes of the 28-spotted potato lady beetle(Henosepilachna vigintioctopunctata) were compared to understand its off-target gene silencing effects. The RNA-seq results revealed that 63 and 44 differentially expressed genes(DEGs) were upregulated and downregulated, respectively, in the ds Hvβ’COPI treated group as compared with the control. Validation of the differential expressions of some selected DEGs via reverse transcription-quantitative PCR(RT-qPCR) analysis confirmed the reliability of the transcriptome analysis results. Further downstream analysis revealed that there were no genes homologous with Hvβ’COPI in H. vigintioctopunctata. Additionally,no genes with a >11 bp continuous match with ds Hvβ’COPI were found in the H. vigintioctopunctata transcriptome. Six genes(Hvcitron, Hvhelicase, Hvtransposase, Hvserine, Hvdynein, and Hv E3 ubiquitin) were selected to examine the offtarget activity of ds Hvβ’COPI based on their potential involvement in various H. vigintioctopunctata metabolic *** severity of silencing these six off-target genes was evaluated by employing RNAi. The RNAi results confirmed the downregulation of the expression of all six genes, although there was no significant lethality. The findings of this study will be helpful in the risk analysis of future RNAi-mediated pest control experiments.

地应力测量是矿山进入深部采矿后需要开展的一项重要工作,高效的地应力测量方法对于确定围岩的稳定性具有重要意义。岩石的超声特性是其物理力学性质、宏细观结构及受力状态等因素的综合体现,以波速为关键参数的声学信息与围岩的应力状态、变形、细观结构、实验条件等因素具有显著的关联性。以众多专家学者研究成果为基础,从波速−应力−应变关联性,考虑岩性、孔隙结构等内在因素影响,以及围压、温度等外界因素影响,波速数学模型四方面介绍了岩石声学特性的研究现状,提出了应力作用下考虑温度因素影响的应力−温度耦合波速关系方程,最后结合深部开采发展需求提出了关于岩石声学−应力研究发展的建议方向。
