A method for Monte Carlo simulation of 2D spin-polarized electron transport in III–V semiconductor heterojunction (FETs) is presented. In the simulation, the dynamics of the electrons in coordinate and momentum space is treated semiclassically. The density matrix description of the spin is...

On the basis of the analysis of main problems existing in current agricultural meteorological service in China, for the purpose of exploring a solution to the “last kilometer†problem in rural meteorological service, this article designed four short message service products with the...

We study the liquidity, defined as the size of the trading volume, in a situation where an infinite number of agents with heterogeneous beliefs reach a trade-off between the cost of a precise estimation (variable depending on the agent) and the expected wealth from trading. The "true" asset...

We study the liquidity, de ned as the size of the trading volume, in a situation where an in nite number of agents with heterogeneous beliefs reach a trade-o between the cost of a precise estimation (variable depending on the agent) and the expected wealth from trading.

We study in this work the liquidity, defined as the size of the trading volume, in a situation when an infinite number of agents with het- erogeneous beliefs reach a trade-off between cost of a precise estimation (variable depending on the agent) and expected profit from trading at the resulting...

We investigate the effects of mergers on the career outcomes of financial analysts. We hypothesize and find that analysts with good earnings forecast performance experience higher turnover during mergers, target analysts are more likely to turnover and the existence of a competing analyst in a...

This paper provides evidence about the unintended consequences arising when small companies are exempted from costly regulations-these firms have incentives to stay small. Between 2003 and 2008, the SEC postponed compliance with Section 404 of the Sarbanes-Oxley Act of 2002 (SOX) for...
