We present a theoretical study of the H+OCl system on an accurate ab initio potential energy surface(PES)investigated by Peterson et al.[***.113(2000)6186].Both the exact time-dependent quantum wave packet(TDWP)and quasi-classical trajectory(QCT)methods are *** results of reaction probabilities for total angular momentum J=0 and the integral cross section calculated by the TDWP are in good agreement with the QCT ***,the nearly forward-backward symmetric product scattering angular distributions and the weak products'rotational alignment effect obtained by the QCT calculations are attributed to a long-lived intermediate reaction process.

Suppressive effect of microRNA-143 in retinoblastoma

International Journal of Ophthalmology(English edition) 2016年第11期9卷 1584-1590页

作者： Li-Lun Wang Hai-feng Hu Yan-Qin feng Department of Ophthalmology Affiliated Hospital of Yan'an University Department of Oncology Affiliated Hospital of Yan'an University

AIM： To investigate micro RNA-143 expression and effect on suppression of retinoblastoma（RB） cells. METHODS： The expression of micro RNA-143 was investigated and compared in normal human retina tissue samples and in RB cell lines of Y79 and Weri1. The micro RNA-143 mimics were transfected into the RB cell lines separately, and its effect on RB cell lines was detected using reverse-transcription quantitative polymerase chain reaction and Western blotting methods. RESULTS： The micro RNA-143 expression was significantly suppressed in RB cell lines. Overexpression of micro RNA-143 significantly lowered cell viability and invasion of the RB cell lines, and increased the number of apoptotic cells. Meanwhile, the Bax expression was up-regulated and much higher in the micro RNA-143 mimics transfected group than that in the negative control and the micro RNA-143 inhibitor groups. CONCLUSION： Micro RNA-143 exhibits suppressive effects in RB. The current study provides the perspective of a potential therapeutic treatment for RB.

A SHIFT-SPLITTING PRECONDITIONER FOR NON-HERMITIAN POSITIVE DEFINITE MATRICES

引用

Journal of Computational Mathematics 2006年第4期24卷 539-552页

作者： Zhong-zhi Bai Jun-feng Yin Yang-feng Su LSEC ICMSEC Academy of Mathematics and Systems Science Chinese Academy of Sciences Beijing 100080 China Department of Mathematics Fudan University Shanghai 200433 China

A shift splitting concept is introduced and, correspondingly, a shift-splitting iteration scheme and a shift-splitting preconditioner are presented, for solving the large sparse system of linear equations of which the coefficient matrix is an ill-conditioned non-Hermitian positive definite matrix. The convergence property of the shift-splitting iteration method and the eigenvalue distribution of the shift-splitting preconditioned matrix are discussed in depth, and the best possible choice of the shift is investigated in detail. Numerical computations show that the shift-splitting preconditioner can induce accurate, robust and effective preconditioned Krylov subspace iteration methods for solving the large sparse non-Hermitian positive definite systems of linear equations.

关键词： Non-Hermitian positive definite matrix Matrix splitting Preconditioning Krylov subspace method Convergence.
