We performed weighted gene coexpression network analysis (WGCNA) to gain insights into the molecular aspects of hepatocellular carcinoma (HCC). Raw microarray datasets (including 488 samples) were downloaded from the Gene Expression Omnibus (GEO) website. Data were normalized using the RMA algorithm. We utilized the WGCNA to identify the coexpressed genes (modules) after non-specific filtering. Correlation and survival analyses were conducted using the modules, and gene ontology (GO) enrichment was applied to explore the possible mechanisms. Eight distinct modules were identified by the WGCNA. Pink and red modules were associated with liver function, whereas turquoise and black modules were inversely correlated with tumor staging. Poor outcomes were found in the low expression group in the turquoise module and in the high expression group in the red module. In addition, GO enrichment analysis suggested that inflammation, immune, virus-related, and interferon-mediated pathways were enriched in the turquoise module. Several potential biomarkers, such as cyclin-dependent kinase 1 (CDK1), topoisomerase 2α (TOP2A), and serpin peptidase inhibitor clade C (antithrombin) member 1 (SERPINC1), were also identified. In conclusion, gene signatures identified from the genome-based assays could contribute to HCC stratification. WGCNA was able to identify significant groups of genes associated with cancer prognosis.

新能源汽车的核心组成部分为能量存储系统,该系统由多个锂电池模块组成,为车辆传动系统提供主要动力。然而模块中的单体电池由于生产制造的缺陷,在性能上往往表现出差异。这些差异的存在会导致电池模块的不完全充放电以及温度分布的不均匀,进而导致循环寿命和电池容量随着时间的推移而降低。为解决这一问题,本工作采用实验和数值方法对性能相似的电池进行了全面的聚类研究,从而得到了电化学性能更好的电池模块。首先通过模块拆解实验来测量电池性能参数,并基于k-均值聚类与支持向量聚类算法设计电池模块,每个模块均由12块电池组成。然后在风冷条件下测量一定时间内电池模块的实际温升,验证聚类设计的效果。研究发现第三类(支持向量聚类)电池模块的性能最佳,充放电最高观测温度为32 ℃。相比之下,其他电池模块的最高温度值要更高:第一类(厂家原装)电池模块为40 ℃,第二类(厂家原装)电池模块为36 ℃,以及第四类(k-均值聚类)电池模块为35 ℃。

This paper presents a method for the design and analysis of reconfigurable parallel robots. The inherent modularity in a parallel robot lends itself as a natural candidate for reconfiguration. By taking the branches as building blocks, many modular parallel robots can be constructed, from which a reconfigurable parallel robot can be realized. Among three types of reconfigurations, namely, geometry morphing, topology morphing, and group morphing, the method presented here is for the last two reconfigurations, thereby advancing the current research that is mainly limited to geometry morphing. It is shown that the module-based method not only provides a systematic way of designing a reconfigurable parallel robot, but also offers a unified modeling for robot analysis. Two examples are provided, one showing the topology morphing and the other showing the group morphing.

我们提出了一种基于低温共烧陶瓷(LTCC)技术的与弯折线天线集成的封装天线系统。该系统采用曲折线贴片天线,封装层和层压多芯片模块(MCM)来集成集成电路(IC)裸芯片。微带馈线用于减少贴片和封装之间的相互作用。为了减少电磁耦合,设计并分析了通孔结构。弯曲线天线的带宽为220 MHz,中心频率为2.4 GHz,最大增益为2.2 dB,辐射效率超过其工作频率的90%。整个系统具有20.2 mm×6.1 mm×2.6 mm的小尺寸,可通过标准LTCC工艺轻松实现。制作了集成了曲折线天线的封装天线系统,实验结果与仿真结果吻合良好。
