Statistical analysis was focused to determine the character of relationship between the 10 most liquid stocks at MSE using ten-year time-series of daily stocks＇ closing price and for the Macedonian Stock Exchange Index （MBI-IO）. The analysis of daily stock returns provided R2 values and confirmed that the proportion of the total correlation in the dependent variable （one stock price） can be explained by the independent variable （other stock price） as well as that accurate forecasting of one stock price movements enables reliable prediction of other stock future price at MSE. Some implications for stock valuation are drawn.展开更多

The two kinds of feedback cavities are used for the fiber laser, which are the buttcontact mirror and the Talbot cavity. According to the model, the transverse mode competitions in different feedback cavities are simulated numerically. The results show that the Talbot cavity can improve in-phase supermode gain, while sunnress other sunerrnodes.展开更多
