A numerical approach to introduce excitations in finite-difference time-domain (FDTD) method that solves time-domain Schrodinger equation is presented in this paper. The proposed approach which used to solve electromagnetic waves incidence has its novel application in this study. It can ensure incident electron wave propagate in a designated direction. The corresponding three-dimensional FDTD formulations...
Using the archaeal 16S rRNA gene, we determined the community structures of archaea of subseafloor sediments (∼9–11 m below seafloor) from two geographically distant cores (MD05-2896, south, water depth 1,657 m; MD05-2902, north, water depth 3,697 m) in the South China Sea. Euryarchaeota accounted for 61.4% of total archaeal clone libraries at MD05-2896 and 56.2% at MD05-2902. At both locations, the...
