The space-time Greens functions for 3-D poststack and 3-D prestack migration in a homogeneous medium are derived under the fareld approximation. These Greens functions can be used to practically compute synthetic migrated images. Examples are given for the recording footprint noise associated with a point scatterer and a meandering river channel. The Greens functions also provide fundamental in...

Abstract In this article, we study a class of nonlinear fractional differential equation for the existence and uniqueness positive solution Hyers–Ulam-type stability. To proceed work, utilize tools fixed point theory analysis to investigate concern theory. We convert into an integral alternative form with help Greens function. Using desired function, studied proposed equation. next section auth...

We present a theory for Raman scattering by current-carrying molecular junctions. The approach combines a nonequilibrium Green's function (NEGF) description of the nonequilibrium junction with a generalized scattering theory formulation for evaluating the light scattering signal. This generalizes our previous study [M. Galperin and A. Nitzan, Phys. Rev. Lett. 95, 206802 (2005); J. Chem. Phys. 1...

Graphene's isolation launched explorations of fundamental relativistic physics originating from the planar honeycomb lattice arrangement of the carbon atoms, and of potential technological applications in nanoscale electronics. Bottom-up fabricated atomically-precise segmented graphene nanoribbons, SGNRs, open avenues for studies of electrical transport, coherence, and interference effects in m...

Two-tiered putting green profiles feature a sand root zone that sits above a layer of gravel, creating a textural boundary where water is perched or preferentially retained (6). The greater the difference in particle sizes, the more water is retained in the fine-textured layer above (8). Hard, brittle, cemented layers have been observed to form at textural boundaries in two-tiered putting green...

An accurate and efficient algorithm for computing non-equilibrium Green’s functions has been developed and used in the simulations of a novel nanoscale MOSFET device structure. The method is based on the principle of nested dissection and demonstrates significant performance improvement from both speed and memory requirements points of view as compared to the state of the art recursive Green’s ...
