Abstract A solution is obtained for the plasma fields generated by an external line current in a slab geometry. The form of the solution is a summation over the various plasma waves which are defined b...

A rapid and simple method for separating and identifying plasma lipoproteins is described. The technique utilizes the “molecular sieving” properties of continuous concave gradient electrophoresis on a slab of polyacrylamide (4 to 26%) gel. Gradient gel electrophoresis is particularly suitable for separating lipoproteins according to their molecular weight. The technique can be used to demonstra...

The theory of electromagnetically induced transparency ~EIT! in a plasma @S. E. Harris, Phys. Rev. Lett. 77, 5357 ~1996!# is examined in the context of a bounded system. It is found via particle simulations that an overdense plasma slab reflects short pulses even in the presence of an EIT passband. However, a two-frequency laser, or ‘‘beatwave,’’ will cascade into a Stokes satellite with a freq...

In this paper, properties of slab deformation in sizing press mill as one of the slab reduction processes in hot rolling mills have been evaluated using the elastoviscoplastic finite element method with explicit formulation. Effect of prarameters such as initial slab width and thickness, reduction, feed pitch, and anvil speed on factors such as dogbone formation, head and tail fishtail profile,...

A subway train-steel spring floating slab track-tunnel coupling dynamic model, considering short and middle-long wavelength random track irregularities, and longitudinal connection between adjacent slabs of steel spring floating slab track, was developed. And the influence of slab length on dynamic characteristics of the system under different track conditions and train speeds are theoretically...

Locally excited plasma waves are generated in a Coulomb crystal by "pushing" with radiation pressure on a rotating cloud of laser-cooled 9Be+ ions. The waves form a stationary wake that is directly imaged through the dependence of the ion fluorescence on Doppler shifts, and theoretical calculations in a slab geometry are shown to accurately reproduce these images. The technique demonstrates a n...

Context. High spectral resolution X-ray observations of classical T Tauri stars (CTTSs) demonstrate the presence of plasma at T ∼ 2−3×106 K and ne ∼ 1011−1013 cm−3, unobserved in non-accreting stars. Stationary models suggest that this emission is due to shockheated accreting material, but they do not allow to analyze the stability of such material and its position in the stellar atmosphere. Ai...

[1] Although mantle slabs ultimately drive plate motions, the mechanism by which they do so remains unclear. A detached slab descending through the mantle will excite mantle flow that exerts shear tractions on the base of the surface plates. This ‘‘slab suction’’ force drives subducting and overriding plates symmetrically toward subduction zones. Alternatively, cold, strong slabs may effectivel...

At present, reducing subgrade settlement of soft soil foundation is a key problem in high-speed railway construction. Pile-slab structure is a widely-utilized form of foundation structure to reduce the subgrade settlement in China. In order to save the engineering cost for high-speed railway construction in developing countries, the author developed a pile-slab structure and named it as the new...

The peaked profile of perpendicular/parallel plasma rotation velocity at internal transport barrier (ITB) is modelled by a Gaussian distribution. Its stabilizing or destabilizing effects on the sheared slab 4, instability arc analyzed, in the finite and weak magnetic shear regions in detail. It is found that the peaked profile of a counter-toroidal rotation at ITB contributes to the formation a...
