Subspace Clustering Algorithm Based on Multi-rule Constraint

Huiping Li 보안공학연구지원센터 2014 International Journal of Multimedia and Ubiquitous Vol.9 No.12

For the fact that telecom data size is extremely huge and the management is much complicated, the paper proposes subspace clustering algorithm based on multi-rule constraint, to mine business knowledge information in a more efficient and accurate manner. By relying on K-means clustering algorithm, the method improves selection and mutation operation of genetic algorithms and thus corrects inappropriate choice of K-means initial clustering centers. Meanwhile, with the use of variable weighting strategy, data classification sparseness in the clustering is overcome. A fast and useful mining method is enabled for massive data. Results show its better performance in terms of computing efficiency, accuracy and ability.

Rapid, economical, and reliable genotyping is an important requirement for germplasm analysis and cultivar identifi cationin crop species. Chinese cabbage ( Brassica rapa L. subsp. pekinensis (Lour.) Hanelt) originated in China and is now aneconomically important vegetable crop worldwide, especially in East Asia. In this study, we evaluated 1167 single nucleotidepolymorphisms (SNPs) among 166 representative Chinese cabbage inbred lines using a KASP genotyping assay. Onthe basis of polymorphisms and principal component analysis, we selected 60 core SNPs distributed on all Brassica rapachromosomes with allele frequencies suffi ciently balanced so as to provide adequate information for genetic identifi cation. The core set of SNPs was used for construction of a neighbor-joining dendrogram, in which the 166 inbred lines wereclustered into spring, summer, and autumn ecotype groups. Clustering of the ecotype groups was better resolved than thatachieved with 1167 and 360 polymorphic SNP datasets. Stability and resolution of the core SNP markers were tested using178 commercial hybrid Chinese cabbage cultivars to confi rm their utility in genetic identifi cation. The set of 60 informativeand stable SNP markers showed high discriminatory power and relatively uniform genomic distribution (4–9 markers perchromosome). The SNPs represent a cost-effi cient and accurate marker set for germplasm analysis and cultivar identifi cationand are suitable for molecular marker-assisted breeding in Chinese cabbage.

Zhenjie Tang,Dongqiu Zhao,Huiping Hu,Rong Li,Jiang Yin 한국전기전자재료학회 2014 Transactions on Electrical and Electronic Material Vol.15 No.2

Pt/Al2O3/La2Si5Ox/SiO2/Si charge trap memory capacitors were prepared, in which the La2Si5Ox film was used as thecharge trapping layer, and the effects of post annealing atmospheres (NH3 and N2) on their memory characteristicswere investigated. La2O3 nanocrystallites, as the storage nodes, precipitated from the amorphous La2Si5Ox film duringrapid thermal annealing. The NH3 annealed memory capacitor showed higher charge storage performances thaneither the capacitor without annealing or the capacitor annealed in N2. The memory characteristics were enhancedbecause more nitrogen was incorporated at the La2Si5Ox/SiO2 interface and interfacial reaction was suppressed afterthe NH3 annealing treatment.

Effect of Annealing Atmosphere on the La₂O₃ Nanocrystallite Based Charge Trap Memory

Tang, Zhenjie,Zhao, Dongqiu,Hu, Huiping,Li, Rong,Yin, Jiang The Korean Institute of Electrical and Electronic 2014 Transactions on Electrical and Electronic Material Vol.15 No.2

$Pt/Al_2O_3/La_2Si_5O_x/SiO_2/Si$ charge trap memory capacitors were prepared, in which the $La_2Si_5O_x$ film was used as the charge trapping layer, and the effects of post annealing atmospheres ($NH_3$ and $N_2$) on their memory characteristics were investigated. $La_2O_3$ nanocrystallites, as the storage nodes, precipitated from the amorphous $La_2Si_5O_x$ film during rapid thermal annealing. The $NH_3$ annealed memory capacitor showed higher charge storage performances than either the capacitor without annealing or the capacitor annealed in $N_2$. The memory characteristics were enhanced because more nitrogen was incorporated at the $La_2Si_5O_x/SiO_2$ interface and interfacial reaction was suppressed after the $NH_3$ annealing treatment.

Zhimin Yu,Mou-Ming Zhao,Huiping Li,Hai-Feng Zhao,Qingli Zhang,Chunyan Wan,Huipin Li 한국생물공학회 2012 Biotechnology and Bioprocess Engineering Vol.17 No.4

High gravity (HG) or very high gravity (VHG)brewing has become popular in modern breweries due to its economic and product quality advantages. However,there are the negative impacts such as the fermentation performance of brewer’s yeast in HG or VHG wort, which are closely related to changes in cell physiological activity. In the present study, 3 kinds of worts, with different gravities, were used to examine the systematic effects on fermentation performance and physiological activity of lager yeast FBY009505 (Saccharomyces pastorianus) and ale yeast FBY0099 (Saccharomyces cerevisiae), as well as the resulting beer flavor. Results showed that the responses of FBY009505 and FBY0099 to the HG or VHG worts were similar. The specific fermentation rate and viability of cropped yeast of FBY009505 and FBY0099 were decreased with increasing wort gravity. The increased wort gravity resulted in the increase of energy charge and the decrease of α-glucosides transport rate and glycolytic enzyme activities. Moreover, the environmental stresses in the HG or VHG wort showed a higher inhibitory activity against α-glucoside transport than glycolytic enzymes. The content of intracellular trehalose and glycerol of FBY009505 and FBY0099 increased with the increase in wort gravity. The results from this study provided a potential means to systematically understand the physiology of brewer’s yeast under HG or VHG conditions.

Prediction of exploration targets based on integrated analyses of source rock and simulated hydrocarbon migration direction: a case study from the gentle slope of Shulu Sag, Bohai Bay Basin, northern China

Changqing Ren,Fugui He,Xianzhi Gao,Dongsheng Wu,Wenli Yao,Jianzhang Tian,Huiping Guo,Yuanxin Huang,Li Wang,Han Feng,Junwei Li 한국지질과학협의회 2019 Geosciences Journal Vol.23 No.6

The Shulu Sag which is a rifted sag with NNE trend is located in the south of Jizhong Depression, Bohai Bay Basin, northern China. The gentle slope and three troughs are situated in the west and east of the sag, respectively. Both of the lower part of Shasan Member (Es3x) and the lower part of Shayi Member (Es1x) act as source rocks in this sag. Researches on the type, quantity, quality and thermal maturity of the respective organic matter have been conducted using Rock-Eval pyrolysis data. Type II is the dominant kerogen in Es1x of all troughs. However, Type II1 and III is the dominant kerogen in Es3x of Middle-Southern and Northern trough, respectively. TOC (total organic carbon) and pyrolysis S2 (hydrocarbon) values suggest that the Es1x source rocks in Middle-Southern and Northern trough are fair to good and poor to fair generative potential of hydrocarbon, separately. The Es3x source rocks in Middle-Southern and Northern trough possess fair to excellent and poor to fair generative potential of hydrocarbon, individually. Tmax (pyrolysis temperature at maximum S2) values indicate that most of Es3x samples are thermally mature, but all Es1x samples are thermally immature. Under large scale condition, the hydrocarbon secondary migration in the upper part of Shasan Member (Es3s), Shaer Member (Es2) and the upper part of Shayi Member (Es1s) have been simulated using fluid potential model with Arcgis 9.3 software. The simulation results reveal the direction of hydrocarbon secondary migration and the distribution of hydrocarbon migration-accumulation units (HMAUS), and also suggest that the hydrocarbon migration direction is obviously controlled by nose-like structure belts where most of hydrocarbons accumulate. That shows high reliability because they are consistent with the hydrocarbon exploration result in this area. On the basis of integrated analyses of source rocks and hydrocarbon migration direction, the following five areas in the gentle slope are identified to be the preferred hydrocarbon accumulation area: Taijiazhuang area, northern and southern Xicaogu area, as well as northern and southern Leijiazhuang area. It is considerably helpful to reduce the risk in hydrocarbon exploration of Shulu Sag.
