Abstract:This paper is mainly concerned with the issues of synchronization criteria of impulsive Lurie systems with time-delay. Based on stability theory of impulsive
differential equation and new comparison theory of impulsive differential system,some simple yet less conservative criteria ensuring impulsive synchronization of the
Lurie systems are derived.A numerical
example is given to illustrate the effectiveness of the method. |

Abstract:The financial information technology talents with practical abilities are an important guarantee for the successful construction of Shanghai as an international
financial center.This thesis analyzes, from the perspective of market demand, the current situations about cultivation of financial information technology talents and
insufficient cultivation of the same, exemplified by construction of a financial information education platform, discusses the reform of financeoriented innovative
cultivation modes, the double-line course system characteristic of the financial industry, and financial practice embodied as experiment, and explores the feasibility of the
abovementioned items, so as to improve the
cultivation of financial information technology talents’ professional abilities. |

Abstract:In this paper, explicit difference scheme, implicit difference scheme and characteristics method are compared to simulate transient flow in product pipeline. The simulation
results of pressure and temperatur can be used to prevent water hammer in the pipeline and improve the efficiency and safety in oil transmission. The stability and accuracy of the
three methods are compared by adopting different time steps. For explicit method, large fluctuation may occur in case of large time step. For implicit method, the results are affected
little by time step, only if the relaxation factor selected is reasonable. For characteristics method, the results have a good convergency and high precision. The results show that, in
the situation of valve shut down in terminal station, it takes about 1.1×104 seconds to return to a new steady state.

Abstract:Molecular docking of 3,5-dihydroxy heptenoates into 3-Hydroxy-3-Methyl-glutaryl coenzyme A reductase (HMGR)and its binding mode were studied. Hydrogen bond is an important interaction in bonding site. The linear correlation coefficient R between hydrogen bond (HMGR)Bond score and pIC50 was0.65. There are hydrogen bond interactions between carboxyl group of high activity compound and HMGR amino acid residues Ser684B,
Lys692B and Lys735A. |

Abstract:Using
Bell function and the generalized three dimensional
Pauli operators, a set of Bell inequalities classifying
the entanglement of triqutrit mixed states is presented.
These inequalities can distinguish fully separable and
bi-separable states. Moreover we present a quantum upper
bound for triqutrit mixed states using generalized Bell
function. |
