  • 关键词:financial time series;Langevin approach;drift parameter;autocorrelation
  • 摘要: We have studied the Langevin description of stochastic dynamics of financial time series. A sliding-window algorithm is used for our analysis. We find that the fluctuation of stock prices can be understood from the view of a time-dependent drift force corresponding to the drift parameter in Langevin equation. It is revealed that the statistical results of the drift force estimated from financial t...

  • 摘要: The local influence analysis is an important problem in statistical inference and some models have been discussed in many literatures This paper deals with the problem of assessing local influences in a multivariate t-model with Rao's simple struc-ture(RSS). Based on Cook's likelihood displacement, the effects of some minor perturbation on the statistical inference is assessed. As an application, ...

  • 关键词:calcium channels L-type;ryanodine receptor;inositol phosphates;phospholipase C
  • 摘要: Aim: Depolarization-induced contraction of smooth muscle is thought to be mediated by Ca^2+ influx through voltage-gated L-type Ca^2+ channels. We describe a novel contraction mechanism that is independent of Ca^2+ entry. Methods: Pharmacological experiments were carried out on isolated rat gut longitudinal smooth muscle preparations, measuring isometric contraction strength upon high W-induced de...

  • 摘要: We propose a new two-type-player prisoner's dilemma game based on the division of work on a square lattice, in which a fraction of the population # are assigned type A and the rest B.In a one-shot two-player game, we let both of their original payoffs be scaled by a same multiplicative factor α > 1, if two neighboring players are of different types; however we leave the payoffs unchanged if they a...

  • 摘要: Based on the weekly closing price of Shenzhen Integrated Index, this article studies the volatility of Shenzhen Stock Market using three different models: Logistic,AR(1) and AR(2). The time-variable parameters of Logistic regression model is estimated by using both the index smoothing method and the time-variable parameter estimation method. And both the AR(1) model and the AR(2) model of zero-mea...

  • 摘要: Guizhou Province is one of the least developed areas with the largest number of counties in poverty and the widest coverage ofkarst landscape in China. The vulnerability of its karst eco-environment seriously threatens the survival of local residents and the development of local economy. Rapid population growth results in higher demand of various resources, which leads to more intensive developmen...
