Invasion by the exotic species Spartina alterniflora, which has high net primary productivity and superior reproductive capacity compared with native plants, has led to rapid organic carbon accumulation and increased methane (CH4) emission in the coastal salt marsh of China. To elucidate the mechanisms underlying this effect, the methanogen community(More)
SUMMARY Efficient extraction of interconnect parasitic parameters has become very important for present deep submicron designs. In this paper, the improved boundary element method (BEM) is presented for 3-D interconnect resistance extraction. The BEM is accelerated by the recently proposed quasi-multiple medium (QMM) technology, which quasi-cuts the(More)
Significant spatial variation in CH4 emissions is a well-established feature of natural wetland ecosystems. To understand the key factors affecting CH4 production, the variation in community structure of methanogenic archaea, in relation to substrate and external environmental influences, was investigated in selected wetlands across China, using denaturing(More)
Invasion of Spartina alterniflora in coastal areas of China increased methane (CH4) emissions. To elucidate the underlying mechanisms, we measured CH4 production potential, methanogen community structure and biogeochemical factors along a coastal wetland transect comprised of five habitat regions: open water, bare tidal flat, invasive S. alterniflora marsh(More)
There is ample evidence that methane (CH4) emissions from natural wetlands exhibit large spatial variations at a field scale. However, little is known about the metabolically active methanogens mediating these differences. We explored the spatial patterns in active methanogens of summer inundated Calamagrostis angustifolia marsh with low CH4 emissions and(More)
With the deep submicron process technology used widely, fast and accurate extraction of parasitic parameters becomes very important for VLSI designs. In this paper, a fast and accurate method is presented for 3-D interconnect resistance extraction. This method is the boundary element method accelerated by the improved Quasi-Multiple Medium (QMM) algorithm.(More)
