Particle orbits and the Rosenbluth-Hinton residual zonal flow are evaluated for the case of a strong equilibrium radial electric field ( ) / r E d d φ ψ ψ = − ∇ as observed in a tokamak pedestal. The ordering used is p i ~ / r E B v c where p B is the poloidal field and i v is the ion thermal speed. The earlier calculations of Kagan and Catto for this regime [Kagan G and Catto P J 2009 Phys. Pl...

Sheared zonal ‡ow helps to reduce the turbulent transport caused by the ion temperature gradient (ITG) mode. Rosenbluth and Hinton (R-H) calculated the residual zonal ‡ow level for radial wavelengths that are much larger than the ion poloidal gyroradius. Their calculation is extended to treat arbitrary radial wavelengths. For the radial wavelengths that approach the ion poloidal gyroradius, but...

The violation of the scaling law for the electric and magnetic form factors of the proton is examined within the cloudy bag model. We find that the suppression of the ratio of the electric and magnetic form factors is natural in the relativistic bag model. The pion cloud plays a moderate role in moving the ratio towards unity at low momentum transfer. The scaling violation increases as the mome...

In the present review, we discuss different aspects of two-photon exchange (TPE) physics in elastic ep scattering at high Q2, as well low Q2. The imaginary part TPE amplitude gives rise to beam and target single-spin asymmetries. Different theoretical approaches calculation these observables are considered. real influences unpolarized cross-section double-spin is, most likely, responsible for d...

The $${{Q}^{2}}$$ dependence of the ratio cross sections with and without spin flip, as well polarization asymmetry in $$e\vec {p} \to e\vec {p}$$ process, has been numerically analyzed using results JLab’s experiments on measurements Sachs form factors $$\vec {e}p process. calculations have made for case where initial (at rest) final protons are fully polarized a common quantization axis, whic...

An algebraic principle for blind source separation is presented in this paper. This separation principle identi"es a (smaller) set of equations whose solutions can blindly extract non-Gaussian signals. The concept of `Mth-order uncorrelatednessa is introduced and it is proven that for Mth-order uncorrelated source signals, signals with nonzero kth-order cumulant (2(k)M) can always be extracted ...

conclusions trichotillomania may also be seen in preschool-aged children and may be associated with separation anxiety disorder. improper and late treatment can be associated with a worsening of the disorder. case presentation a 4.5-year-old girl without any psychiatric disorders in the family. she was cared for by her mother, and the child had a history of separation anxiety. after detection o...

The effects of incoherence on the three-wave coupling process backward stimulated Raman scattering (SRS) in inhomogeneous plasmas are investigated theoretically and numerically via a model. impact plasma wave nonlinearity is taken into account, namely, effect trapped electrons nonlinear frequency shift electron wave. Incoherence introduced seed wave, laser pump bandwidth associated with Lorentz...
