Principle Fluctuation Modes of the Global Stock Market

The purpose of this work is to study the principle fluctuation modes of the global stock market,which is regarded as a complex system.It is proposed that the systematic risk can be reflected by the trace calculated from the cross-correlation matrix,and the integrity can be classified into clusters according to the plus-minus signs of the elements of the eigenvectors corresponding to several top largest eigenvalues whose total value accounts for more than 60 percent of the trace.The principle fluctuation modes of 30 stock markets are in the same direction in each year of 2005-2010.According to the classification criteria proposed here,the stock markets of the Americas,Europe and Asia & Oceania are automatically classified into different clusters,while Brazil,Russia and China are separated.

A New Method of Calculating Trap Depth of Rare Earth Materials

The mainly characteristic of trapping materials is the trap depth. So it is significant to calculate the trap depth for the trapping materials. A new method of calculating trap depth, which is based on energy band and using rate equations to analyze thermoluminescence, was brought forward. This method which uses the rate equations of the process and the thermoluminescence curve can replace traditional methods such as first order or second order kinetics. The trap depth of SrAl2O4：Eu^2＋ , Dy^3＋ and Sr4Al14O25：Eu^2＋ , Dy^3＋ was estimated from the glow curve. Then the numerical solution of the trap depth can be obtained. From the results of experiments and calculations, this method can accurately indicate the whole process.

Compared with the device using PVK/Eu(asprin) 3phen blend as the light emitting layer, the emission of Eu 3+ in the PVK/Tb 0.5 Eu 0.5 (asprin) 3 phen blend is greatly enhanced along with the quenching of the emission of PVK.

Reliability Study on the Risk Precontrol Management System of Coal Mines Safety

Risk precontrol management system of coal mines safety( RPMSCS) provides a set of preventive safety management strategy for high-risk coal industries, which has captured extensive attentions. Fundamentally,there are several membership systems with subsystems in the management system, and the subsystem reliability has an important influence on the management system performance. Through analyzing the structure characteristics of the management system,the phase type distribution was employed to analyze its subsystem reliability by considering repair process and three states including working,fail-abnormal,and fail-emergency states. The reliability indices of the subsystem were derived respectively,including the probabilities that the subsystem in three states,mean time to the first failure, mean time to first failemergency,mean working time to first fail-emergency,and mean maintenance time to the first fail-emergency, are derived respectively. The probabilities of the membership systems and the management system in three states were also derived. Some numerical examples were used to show the procedures. The result is important for better understanding the management system operation and improving its operational performance from the respect of system reliability.

Electrochemical performance of nano-scale β-Ni(OH)_2 prepared at different transformations of pH value

The influence of transforming pH values on the electrochemical performance of nano-scale Ni （OH）2 was analyzed. The measurement results of XRD indicate that the nano-scale Ni （OH） 2 prepared at different transformations of pH value is β （ Ⅱ ）-phase with different crystal lattice parameters. Cyclic voltammograms （CV） and electrochemical impedance spectroscopy（EIS） measurement results show that transformations of pH value affect the proton diffusion coefficient （D） and charge-transfer resistance （Re,） of the material. The simulation of.cell experiment shows that the sample prepared at a pH of 10. 1 exhibits the maximum specific capacity （327.8 mAh/g） and higher discharge platform, the discharge performance of electrodes depends on both D and Rct, so the kinetics characteristics that electrodes reaction is controlled by both mass-transfer step and charge- transfer step are put forward.

A new model of the harmonic control based on Hadamard product

In terms of Hadamard product, a new model is proposed for the control of connection coefficients of the state variables of the systems. The control law to stabilize the systems via the regulations of connection coefficients is obtained via a Hadamard product involved bilinear matrix inequalities. This new control model may be of significant applications in many fields, especially may be of some special sense in the emergency control such as isolation and obstruction control.

Protective Effect of Shenfu Injection on Rats with Chronic Heart Failure Induced by Doxorubicin

[Objectives] To determine the protective effect of Shenfu injection( SFI) on chronic heart failure( CHF) in rats induced by doxorubicin. [Methods] CHF was induced by doxorubicin via intraperitoneal injection in rats. The cardiac function parameters,the heart index,the serum brain natriuretic peptide( BNP) level and cardiac histopathology were measured 4 weeks after Shenfu injection treatment. [Results]Shenfu injection remarkably improved the heart index and cardiac histopathology,increased the heart rate( HR),left ventricular systolic pressure( LVSP),maximum rising rate of left ventricular pressure( + dp/dtmax) and dropping rate of left ventricular pressure(-dp/dtmax),reduced the left ventricular end-diastolic pressure( LVEDP) and serum BNP level of rats with CHF induced by doxorubicin. [Conclusions]Shenfu injection exerts protective effect on CHF induced by doxorubicin.
