Various aspects of the C-metric representing two rotating charged black holes accelerated in opposite directions are summarized and its limits are considered. A particular attention is paid to the special-relativistic limit in which the electromagnetic field becomes the “magic field” of two oppositely accelerated rotating charged relativistic discs. When the acceleration vanishes the usual elec...

We discuss techniques for accelerating the self-consistent field iteration for solving the Kohn–Sham equations. These techniques are all based on constructing approximations to the inverse of the Jacobian associated with a fixed point map satisfied by the total potential. They can be viewed as preconditioners for a fixed point iteration. We point out different requirements for constructing prec...

The accelerating and focusing wake fields that can be excited by a short laser pulse in a hollow underdense plasma are examined. The evacuated channel in the plasma serves as an optical fiber to guide the laser pulse over many Rayleigh lengths. Wake fields excited by plasma current at the edge of the channel extend to the center where they may be used for ultrahigh gradient acceleration of part...

The concept of the nonholonomic deformation formulated recently for the AKNS family is extended to the Kaup-Newell class. Applying this construction we discover a novel mixed integrable hierarchy related to the deformed derivative nonlinear Schrödinger (DNLS) equation and found the exact soliton solutions exhibiting unusual accelerating motion for both its field and the perturbing functions. Ex...

Solving large combinatorial optimisation problems is often time consuming, and thus there is interest in accelerating current algorithms by building application specific computers. This paper focuses on accelerating general local search meta-heuristics, such as simulated annealing and tabu search, and presents an architecture for this class of algorithms. As a design case study we describe a sp...

Now in its 30th year of designing electron microscopes. JEOL is still searching after its ma|or theme Higher resolution capability The JEM-200CX electron microscope and the JSM-F15 field emission scanning microscope are two of our latest developments born out of such continued research. They are now winning broad acceptance as a topnotch TEM and SEM. in many respects such as resolution, stabili...

Heterogeneous Multi-Processor System-on-Chip (MPSoC) and media processing are comprehensively applied in mobile electronic commerce. And heterogeneous MPSoCs provides more opportunities for parallelization accelerating of sequential media algorithms. However, the parallelization researches of heterogeneous MPSoC applications lags far behind the development of MPSoC hardware platform. Therefore,...

We develop a fully covariant, well-posed 5D effective action for the 6D cascading gravity brane-world model, and use this to study cosmological solutions. We obtain this effective action through the 6D decoupling limit, in which an additional scalar degree mode, π , called the brane-bending mode, determines the bulk-brane gravitational interaction. The 5D action obtained this way inherits from ...
