We developed a new emission inventory for Asia (Regional Emission inventory in ASia (REAS) Version 1.1) for the period 1980–2020. REAS is the first inventory to integrate historical, present, and future emissions in Asia on the basis of a consistent methodology. We present here emissions in 2000, historical emissions for 1980–2003, 5 and projected emissions(More)
—This letter provides the first report of 160-Gb/s optical time-division-multiplexed transmission with all-channel independent modulation and all-channel simultaneous demultiplexing. By using a multiplexer and a demultiplexer based on periodically poled lithium niobate and semiconductor optical amplifier hybrid integrated planar lightwave circuits, 160-km(More)

A prototype scanning tunneling microscope has been built in the Laboratory for Manufacturing and Productivity at MIT previous to this thesis work. The purpose of this thesis work is to improve the performance of the scanning tunneling microscope for other applications such as the surface modification in nanometer range. The scanning tunneling microscope has(More)
