In this paper, we consider the acceleration of plasma fluxes in crossed electromagnetic fields. The possible technical approach to a prospective accelerator is discussed. A simple hydrodynamic model describing dynamics ring these fields proposed. Based on model, estimations basic characteristics for accelerated flux are calculated typical experimental conditions.

‎‎a natural generalization of two dimensional cyclic code ($t{tdc}$) is two dimensional skew cyclic code‎. ‎it is well-known that there is a correspondence between two dimensional skew cyclic codes and left ideals of the quotient ring $r_n:=f[x,y;rho,theta]/_l$‎. ‎in this paper we characterize the left ideals of the ring $r_n$ with two methods and find the generator matrix for two dimensional s...

How do people get attention to operate at peak efficiency in high-pressure situations? We tested the hypothesis that the general mechanism that allows this is the maintenance of multiple target representations in working and long-term memory. We recorded subjects' event-related potentials (ERPs) indexing the working memory and long-term memory representations used to control attention while per...

ntroduction:  monte  carlo  simulation  is  the  most  accurate  method  of  simulating  radiation  transport  and  predicting doses at different points of interest in radiotherapy. a great advantage of the monte carlo method  compared  to  the  deterministic  methods  is  the  ability  to  deal  accurately  with  any  complex  geometry.  its  disadvantage is the extremely long computing time r...

Computational science research components were vital parts of the SciDAC1 accelerator project and are continuing to play a critical role in newly-funded SciDAC-2 accelerator project, the Community Petascale Project for Accelerator Science and Simulation (ComPASS). Recent advances and achievements in the area of computational science research in support of petascale electromagnetic modeling for ...

In this paper, we propose an ORB hardware accelerator design. Feature-based SIFT and SURF hardware accelerators that detect features in real-time require high hardware costs. To overcome this disadvantage, an ORB algorithm consisting of simple calculations was designed as the hardware accelerator. A comparison between the proposed ORB hardware accelerator with SIFT and SURF accelerators reveale...

objective: cell vital function has correlation with mechanical loadings that cell experiences. here, effects of in-vitro combined cyclic-static stretch on proliferation of human mesenchymal stem cell (hmsc) were evaluated. materials and methods: hmscs were cultured on gelatin coated elastic membranes, and exposed to stretch loading. four different regimes of cyclic, static, combined cyclic-sta...

The results derived in Ref. 2 have been used to calculate a sample set of parameters1 for a superconducting version of the two-mile SLAC accelerator. These calculations have been carried out in order to provide a basis for further technical discussions. Beam Energy The energy goal of 100 GeV (10 MeV/ft.) has been chosen since this energy is sufficiently higher than the 20 GeV capability of the ...
