Based on authors draw conclusions forming legal mechanism according to principles reliance main functions state. particular, social function stipulates that categorization allowed only for estimation need material assistance, supplementary guarantees and favours. Economical includes execution fina...
The main objective of this research is to forecast the daily direction of Standard & Poor's 500 (S&P 500) index using an artificial neural network (ANN). In order to select the most influential features (factors) of the proposed ANN that affect the daily direction of S&P 500 (the response), design of experiments are conducted to determine the statistically significant factors among 27 potential...
The present article describes the recent catalytic asymmetric methods developed in our group to access enantioenriched chiral aldehydes. We are generally aiming at developing complementary strategies based on either homogeneous organometallic catalysts or amino-catalysts and sometimes on a combination of both. Recent successes comprise a perfectly redox-economical iridium-catalyzed asymmetric ...
Abstract Due to the prevalence of trifluoromethyl group (CF 3 ) in high‐value organic compounds, there is a constant demand for more selective, efficient and economical trifluoromethylation strategies. In this report we present detailed experimental computational investigations into use cheap atom‐economical CF I transition metal catalyzed trifluoromethylation. The mechanistic insight gained al...
Despite their importance, forecasts of real economic activity can be unreliable. Forecasts based on macroeconomic models are often hindered by the lack of timely and accurate data and the complexity of the forecasting model. These difficulties have led to a growing interest in using financial variables to supplement traditional model-based forecasts of real economic activity. The advantages of ...
