为了解轮虫线粒体基因组研究现状和存在的问题，通过对轮虫线粒体基因组研究相关文献的搜索、收集、阅读和归纳总结，通过对轮虫线粒体基因组序列进行分析和统计，提出轮虫线粒体基因组研究发展趋势及应用。随着分子生物学技术特别是测序技术的发展，轮虫线粒体基因组序列测定相关研究也逐步开展起来。目前已经报道的轮虫线粒体全序列有12个记录，共6种物种，主要集中于蛭态轮虫和臂尾轮属轮虫，蛭态轮虫线粒体基因组含1条环形染色体，臂尾轮属轮虫含两条环形染色体。所有轮虫线粒体基因组均含有基本的13个线粒体蛋白质编码基因，2个rRNA编码基因，22个tRNA编码基因(18～32个)。另外，少数轮虫如萼花臂尾轮虫含有额外的cytb基因拷贝。由于轮形动物中的轮虫体型微小，克隆培养困难，研究人员相对较少，轮虫线粒体基因组测序有待进一步深入。线粒体基因组研究中获得的序列可以用于轮虫系统发生关系研究、轮虫线粒体基因组比较学研究、轮虫隐种研究、轮虫分子鉴定研究、轮虫地理谱系学研究。

目的:王家大院恒贞堡作为中国传统合院式民居的瑰宝,不仅规模宏大、设计精巧、装饰秀美,而且在空间设计层面也汲取了合院民居的精髓,观者在恒贞堡中游览时,能充分感受到其蕴含的空间艺术。文章探究该建筑群院落空间产生的丰富艺术效果,旨在为院落空间设计提供思路与策略。方法:文章以格式塔(Gestalt)空间认知理论及柯林罗(Colin Rowe)提出的透明性理论为基础,以院落空间之间的连接方式为切入点,排除了建筑群落中复杂的装饰细部,从视觉认知和行进认知两个层面出发,对该建筑群中因建筑单元不同连接方式所带来的多重复合空间进行分析,并对其原型进行提取。结果:通过对空间原型的提取,发现恒贞堡中空间艺术效果较强的院落布局更加符合透明性理论所提出的“深空间”和“层化空间”。结论:在当今建筑设计中,尤其是在传统合院式建筑设计中,应更加注重“深空间”和“层化空间”的塑造,应对空间的进深、层次等进行较为明显的刻画,在层次刻画的基础上,进一步进行建筑单体形式、装饰等细部刻画,以取得良好的空间艺术效果。

Developing bifunctional electrocatalysts for overall water splitting reaction is still highly desired but with large challenges. herein, an amorphous Fe Co Ni-S electrocatalyst was developed using thioacetamide for the sulfuration of Fe Co Ni hydroxide during the hydrothermal process. The obtained catalyst exhibited an amorphous structure with hybrid bonds of metal-S bond and metal-O bonds in the catalyst system. The optimized catalyst showed a largely improved bifunctional catalytic ability to drive water splitting reaction in the alkaline electrolyte compared to the Fe Co Ni hydroxide. It required an overpotential of 280 m V and 80 m V(No-IR correction) to offer 10 m A/cm^(2)for water oxidation and reduction respectively;a low cell voltage of 1.55 V was required to reach 10 m A/cm^(2)for the water electrolysis with good stability for12 h. Moreover, this catalyst system showed high catalytic stability, catalytic kinetics, and Faraday efficiency for water splitting reactions. Considering the very low intrinsic activity of Fe Co Ni hydroxide, the efficient bifunctional catalytic ability should result from the newly formed hybrid active sites of metallic metal-S species and the high valence state of metal oxide species. This work is effective in the bifunctional catalytic ability boosting for the transition metal materials by facile sulfuration in the hydrothermal approach.

As an extension of networked control systems, cloud control systems(CCSs) have emerged as a new control paradigm to improve the service quality of emerging control missions, such as data-driven modeling and automated vehicles. Existing studies have used the workflow-based restructured method to optimize the computation-intensive algorithms in the CCSs. However, the challenges here are how to define and submit these algorithms' workflows as cloud services and execute these algorithms' workflows in a containerized manner. Based on these challenges, we propose a containerized solution for the control-algorithm-as-a-service(C3aS) in the CCSs, namely Control Service. It offers the control algorithm as a cloud workflow service and uses a customized workflow engine to realize the containerized execution. First, we employ a cloud workflow representation method to define a control algorithm into an abstract cloud workflow form. Afterward, we provide a cloud service representation of the abstract cloud workflow. Next, we design a workflow engine and submit the cloud service to this workflow engine to implement containerized execution of this cloud service in the CCSs. In the experiment, we discuss the cloud service form and containerized implementation of the subspace identification method. Experimental results show that the proposed Control Service has significant performance advantages in computational time, reduction percentage, and speedup ratio compared with the baseline method.
