Based on the foundation laid by the h-index we introduce and study the R- and AR-indices. These new indices eliminate some of the disadvantages of the h-index, especially when they are used in combina-tion with the h-index. The R-index measures the h-core’s citation intensity, while AR goes one step further and takes the age of publications into account. This allows for an index that can actually in-crease and decrease over time. We propose the pair (h, AR) as a meaningful indicator for research evaluation. We further prove a relation characterizing the h-index in the power law model.

目的探索通过腺嘌呤诱导的肾衰竭大鼠构建腹主动脉腔静脉内瘘(abdominal aortocaval fistula,ACF)模型,为后续机制及干预研究提供合适的动物模型。方法选择成年雌性Sprague-Dawley大鼠(250~300 g),按6∶1比例采用区组随机分组法随机分为肾衰竭组(n=60,0.75%腺嘌呤饲料)和对照组(n=10,不含腺嘌呤的相同饲料),喂饲4周后,肾衰竭组按1∶1比例采用区组随机分组法选取30只行开腹手术构建ACF模型(肾衰竭+ACF组)。通过血肌酐及血尿素氮检测及Masson染色评估肾衰竭模型的建立,应用小动物超声成像系统验证ACF模型的构建情况。ACF手术6周后取材,心脏采血法取血并留取ACF大鼠血管组织进行病理学(HE染色)研究。结果喂饲4周时,与对照组(n=10)比较,肾衰竭组(n=10)大鼠血肌酐[(63.8±23.5)μmol/L比(33.0±3.8)μmol/L,Z=3.651,P<0.001]和血尿素氮[(13.1±6.9)mmol/L比(5.3±0.6)mmol/L,Z=3.254,P=0.001]水平均较高。Masson染色结果显示肾衰竭组肾小管间质炎性细胞浸润、肾小管上皮细胞萎缩、间质纤维化及血管损伤等病理改变。ACF术后5只大鼠死亡,存活率为83.3%。多普勒超声结果显示,肾衰竭+ACF组通畅(23/25)的ACF吻合口处探及动脉向静脉分流的湍流血流。HE染色结果显示,肾衰竭+ACF组ACF静脉流出道出现典型的偏心性新生内膜增生。结论腺嘌呤诱导的肾衰竭大鼠ACF模型构建成功,ACF表现典型的偏心性新生内膜增生,该模型可为自体动静脉内瘘新生内膜增生的机制研究及干预研究提供可靠的动物模型。

针对电力系统的虚假数据注入攻击,研究基于无监督机器学习的电力入侵检测方法。首先,构建稀疏且隐蔽的虚假数据注入攻击(False Data Injection Attacks,FDIAs)模型,得到优化后的FDIAs;其次,采用孤立森林、隐马尔可夫模型两种无监督机器学习算法构建入侵检测框架,分别通过构建二叉树和孤立树、状态序列的预测等实现电力系统的FDIAs入侵检测;再次,采用合理的性能指标全面地对入侵检测性能进行评估;最后,与极端梯度提升、随机森林等监督机器学习算法进行对比实验,基于IEEE电力系统平台验证基于孤立森林等无监督机器学习入侵检测算法的优劣。实验结果表明:无监督机器学习算法可自动从数据中发现特征,相对于基于极端梯度提升、随机森林的入侵检测方法的失效,基于孤立森林的入侵检测方法在无标签数据的前提下,其综合F1-score仍达到0.9942。

The Brassicaceae family halophyte Thellungiella halophila has a high salinity tolerance and serves as a valuable halophytic genetic model plant with experimental convenience similar to Arabidopsis thaliana. A cDNA library of Thellungiella was generated from salt-treated seedlings including rosettes and roots. More than 1000 randomly selected clones were sequenced and 946 expressed sequence tags （ESTs） were generated. The accession numbers of our EST data are available online in the GenBank database from EC598928 to EC599965. In total 679 unique clusters were assembled, and 632 （93%） had BLASTX hits in the nr databases and 7% are Thellungiella unique. According to the Gene Ontology （GO） hierarchy, 385 of 679 unigenes were categorized. Compared with public Arabidopsis microarray data, our results provide more potential salt tolerance genes in Thellungiella. These results will provide a broader coverage into Thellungiella transcriptome and benefit the discovery of salt tolerance related genes.

Scientometrics is an emerging academic field for the exploration of the structure of science through journal citation relations. However, this article aims to study those subject-relevant journals' contents rather than studying their citations contained therein with the purpose of discovering a given disciplinary structure of science such as mechanics in our case. Based on the title wordings of 68,075 articles published in 66 mechanics journals,and using such research tools as the word frequency analysis, multidimensional scaling analysis and factor analysis, this article analyzes similarity and distinctions of those journals' contents in the subject field of mechanics. We first convert complex internal relations of these mechanics journals into a small number amount of independent *** group of selected mechanics journals is then classified by a cluster analysis. This article demonstrates that the relations of the research contents of mechanics can be shown in an intuitively recognizable map, and we can have them analyzed from a perspective by taking into account about how those major branches of mechanics, such as solid mechanics,fluid mechanics, rational mechanics(including mathematical methods in mechanics), sound and vibration mechanics, computational mechanics, are related to the main thematic tenet of our study. It is hoped that such an approach, buttressed with this new perspective and approach, will enrich our means to explore the disciplinary structure of science and technology in general and mechanics in specific.
