Abstract: A high slope with a length over 400 meters will be formed at the Lianyungang nuclear power station after the second period of engineering excavation. After systematically analyzing the engineering geological conditions, the stability of the slope is evaluated by means of engineering comparison and pole projection in corporation with limiting equilibrium method and two-dimensional and three-dimensional finite element method, and the slope design plan is also made.

Abstract: The expression of the elastic field round the outside of the disk inclusion has been deduced analytically by the method of the harmonic and biharmonic potentials. The formulation of the stress intensity factors of the disk inclusions in terms of its eign-strains is resulted. The aspects of the results obtsined as well as its availability have also been discussed.

Abstract: To show the effectiveness of CLUSS, we performed an extensive clustering on COG database. To demonstrate its ability to deal with hard-to-align sequences, we tested it on the GH2 family. In addition, we carried out experimental comparisons of CLUSS with a variety of mainstream algorithms. These comparisons were made on hard-to-align and easy-to-align protein sequences. The results of these experiments show the superiority of CLUSS in yielding clusters of proteins with similar functional activity.We have developed an effective method and tool for clustering protein sequences to meet the needs of biologists in terms of phylogenetic analysis and prediction of biological functions. Compared to existing clustering methods, CLUSS more accurately highlights the functional characteristics of the clustered families. It provides biologists with a new and plausible instrument for the analysis of protein sequences, especially those that cause problems for the alignment-dependent algorithms.With the rapid burgeoning of protein sequence data, the number of proteins for which no experimental data are available greatly exceeds the number of functionally characterized proteins. To predict a function for an uncharacterized protein, it is necessary not only to detect its similarities to proteins of known biochemical properties (i.e., to assign the unknown protein to a family), but also to adequately assess the differences in cases where similar proteins have different functions (i.e., to distinguish among subfamilies). One solution is to cluster each family into distinct subfamilies composed of functionally related proteins. Subfamilies resulting from clustering are easier to analyze experimentally. A subfamily member that attracts particular interest need be compared only with the members of the same subfamily. A biological function can be attributed with high confidence to an uncharacterized protein, if a well-characterized protein within the same cluster is already known. Conversel
Photoelectron spectroscopy of terpenoids and prediction of their rate constants in atmospheric oxidation reactions

Chinese Science Bulletin , 2010, DOI: 10.1007/s11434-010-4154-8
Abstract: The electronic structures of six mono-terpenoids and two of their oxygenated derivatives were studied by He I photoelectron spectroscopy (PES). The observed bands were interpreted on the basis of empirical arguments and theoretical calculations. The first vertical ionization potentials for β-pinene, α-terpinene, terpinolene, γ-terpinene, limonene, myrcene, citral, and terpinene-4-ol were determined to be 8.73, 7.57, 8.26, 8.30, 8.53, 8.68, 8.71, and 8.77 eV, respectively. Most of these values have not been determined by PES before. The correlations of the first vertical ionization potentials of these compounds to the natural logarithms of rate constants for their reactions with the radicals OH, NO3, and O3 were determined. The correlation coefficients for their reactions with OH, NO3, and O3 were 0.97, 0.91, and 0.95, respectively. This method is a powerful technique for predicting the rate constants for the atmospheric oxidation reactions of terpenoids.

A novel hierarchical clustering algorithm for gene sequences
Wei Dan,Jiang Qingshan,Wei Yanjie,Wang Shengrui
BMC Bioinformatics , 2012, DOI: 10.1186/1471-2105-13-174
Abstract: Background Clustering DNA sequences into functional groups is an important problem in bioinformatics. We propose a new alignment-free algorithm, mBKM, based on a new distance measure, DMk, for clustering gene sequences. This method transforms DNA sequences into the feature vectors which contain the occurrence, location and order relation of k-tuples in DNA sequence. Afterwards, a hierarchical procedure is applied to clustering DNA sequences based on the feature vectors. Results The proposed distance measure and clustering method are evaluated by clustering functionally related genes and by phylogenetic analysis. This method is also compared with BlastClust, CD-HIT-EST and some others. The experimental results show our method is effective in classifying DNA sequences with similar biological characteristics and in discovering the underlying relationship among the sequences. Conclusions We introduced a novel clustering algorithm which is based on a new sequence similarity measure. It is effective in classifying DNA sequences with similar biological characteristics and in discovering the relationship among the sequences.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0016930
Abstract: Cynanchum komarovii Al Iljinski is a desert plant that has been used as analgesic, anthelminthic and antidiarrheal, but also as a herbal medicine to treat cholecystitis in people. We have found that the protein extractions from C. komarovii seeds have strong antifungal activity. There is strong interest to develop protein medication and antifungal pesticides from C. komarovii for pharmacological or other uses.
Surface pollen assemblages of human-disturbed vegetation and their relationship with vegetation and climate in Northeast China
ManYue Li,YueCong Li,QingHai Xu,RuiMing Pang,Wei Ding,ShengRui Zhang,ZhiGuo He
Chinese Science Bulletin , 2012, DOI: 10.1007/s11434-011-4853-9
Abstract: Comparison of pollen assemblages in different areas of northern China showed that pollen concentrations reflect the intensities of human impact to some degree. For example, pollen concentrations decrease as human impacts increase in intensity. The cereal pollen proportions in farmland differed by area. In Northeast China, cereal pollen proportions were distinctly higher than in most other areas of northern China, suggesting differences in planting habits and climate.
