RNA interference （RNAi） technology has the potential to be used in pest management in crop production. Here, the transcriptome of Nephotettix cincticeps （Uhler） was deeply sequenced to investigate the systematic RNAi mechanism and candidate genes for dsRNA feeding. In our datasets, a total of 81 225 transcripts were obtained with the length from 150 bp to about 4.2 kb. Almost all the genes related to the RNAi core pathway were proved to be present in N. cincticeps transcriptome. Two transcripts that respectively encode a systemic interference defective （SID） were identified in our da- tabase, indicating that the systematic RNAi pathway can function effectively in N. cincticeps. Our datasets not only supply basic gene information for the studies of gene expression and functions in N. cincticeps, such as the control genes for gene expression analysis, but also provide candidate genes for RNAi pest management, such as the genes that encode P450 monooxygenase, V-ATPase and chitin synthase.

The Hamiltonians of the SU(3) Gaudin model are constructed based on the nonrelativistic limit of the SU(3) chain. After the quantum determinant being well defined, the eigenvectors and eigenvalues of the Hamiltonians of the SU(3) Gaudin model are given. These results can be generalized to any number of constituting spins (SU( N) ).

Corrosion inhibition of tolytriazole for galvanized steel was studied in 5 mM NaCl by using potentiodynamic polarization and electrochemical impedance spectroscopy(EIS), scanning vibrating electrode technique(SVET). The results of EIS and polarization tests indicate that tolytriazole is effective in corrosion inhibition of galvanized steel. As the concentration of tolytriazole is increased to 0.01 M, the inhibiting efficiency reaches above 98%. The low values of anodie and cathodic current density in SVET maps suggest that the complex of tolytriazole with galvanized steel inhibits the anodic and cathodie reactions of corrosion of zinc. The adsorption behaviour of tolytriazole is found to conform to Langmuir adsorption isotherm, which is typical chemical adsorption.

The universal parameter nonorthogonal tight binding scheme proposed by Menon and Subbaswamy was used to optimize the geometrical structures, binding energies and electron affinities of small germanium clusters Ge n ( n =2—20). A complete agreement with available ab initio results from the lowest energy structures for Ge 2—Ge 6 was obtained and reasonable structures for these clusters were predicted and compared with those of corresponding silicon clusters in the range of n =7—20 . The averaged discrepancy with experiments in binding energies for n =2—7 is about 6% and the calculated electron affinities agree well with the measured values in the range of n =2—8 as well.

modifying substrates through mineralization is a popular way to improve the osteogenic performance. Screening of the best mineralization characteristics on specific substrates for stem cells is meaningful but not fully studied. In this paper, poly（lactic-co-glycolic acid）/hydroxyapatite （PLGA[HA, PH） microsphere scaffolds with superficial pores were fabricated by a low-temperature fusion method. After the mineralization in the 5x stimulated body fluid （SBF） for 0, 7, 12 and 24 h, four mineralized scaffolds （MPH-0, MPH-7, MPH-12 and MPH-24） with different apatite topographies were obtained. It was found that the surface of MPH-7 was evenly decorated with abundant micro-pores, MPH-12 with dense and plain apatite layer, and MPH-24 with small spherical bumps. The responses of mouse bone mesenchymal stem cells （mBMSCs） to the four scaffolds were further studied. The results showed that MPH-7 and MPH-24 had more obvious effects on mBMSCs attachment, proliferation and differentiation than MPH-0 and MPH- 12. This work indicated that to obtain the maximum improvement, the mineralization characteristics had to be carefully chosen. This was noteworthy in the chemical modification of surfaces to form the functionalized scaffolds for bone repair.
