China has set an ambitious target to increase its wind power capacity by 35 GW from 2007 to 2020. The country's hunger for clean power provides great opportunities for wind energy investors. However, risks from China's uncertain electricity market regulation and an uncertain energy policy...

Let [zeta]t, t[greater-or-equal, slanted]0, be a process taking nonnegative values, Tr=inf{t0;[zeta]tr}, r0, and [psi] a nondecreasing function. An interesting question is: Is it possible to bound E[psi](Tr) above and below by expectations of functions of [zeta]t? We answer this question and give...

This paper uses a real options approach (ROA) for analysing the effects of government climate policy uncertainty on private investors' decision-making in the power sector. It presents an analysis undertaken by the International Energy Agency (IEA) that implements ROA within a dynamic programming...

We propose a physical scheme for teleporting an unknown atomic state in cavity QED. Our scheme does not involve the Bell-state measurement. The most distinctive advantage of our scheme is that teleportation and distillation procedure can be realized simultaneously. In addition, the current...

In this paper, we propose two physical schemes, which can teleport unknown atomic state from user A (Alice) to user B (Bob) using the W class state as quantum channel. The two schemes are all based on Cavity QED techniques. The fidelity of the teleported state in the two schemes is equal to 1.0,...
