    Magnetic circular x-ray dichroism in Fe7S8 and Fe7Se8 (abstract) : The 40th annual conference on magnetism and magnetic materials (1996)

    Notes: Magnetic circular dichroism (MCD) in core-level absorption provides insights into the element-specific and site-selective magnetic states of various magnetic materials. Fe7S8 and Fe7Se8 have the pseudo-NiAs-type crystal structure and are ferrimagnetic below 578 and ∼450 K, respectively. We have measured MCD spectra in the Fe 2p (L2,3) and Fe 3p (M2,3) core-level absorption of these compounds. The L2,3 MCD spectra were taken at ∼80 K with the total electron yield method. The M2,3 MCD spectra were measured at room temperature with the reflection method using the magnetic-field modulation technique. Both experiments were made using circularly polarized undulator radiation. The L2,3 MCD spectra were found to exhibit a negative peak at the L3 edge with a maximum intensity of ∼10−2 and a weaker positive peak at the L2 edge. The MCD spectrum of Fe7S8 showed sideband features near the L3 edge. Utilization of the magnetic-field modulation method allowed a detection of small MCD signals around the M2,3 edges; the maximum signal intensity was of the order of ∼3×10−3. The M2,3 MCD spectrum of Fe7S8 showed a MCD signal for a prethreshold multiplet, while that of Fe7Se8 exhibited no appreciable MCD signal for a prethreshold multiplet. The features observed in the L2,3 MCD and M2,3 MCD are consistent with an electronic band-structure calculation reported recently. © 1996 American Institute of Physics.

    Notes: Background Th2 and Th1 cells have been suggested to express CCR3/CCR4 and CCR5/CXCR3, respectively.Objective We examined CCR3, CCR4, CCR5 and CXCR3 expression and cytokine production in peripheral blood CD4+ T cells from patients with atopic dermatitis (AD), which has been postulated to be a Th2-type cell-mediated disease, and then analysed the possible correlation between these values and the levels of several clinical parameters.Methods Intracellular cytokine production and chemokine receptor expression in peripheral blood CD4+ T cells from 40 AD patients and 20 sex- and age-matched healthy control subjects were studied by flow cytometry.Results The frequencies of IL-4- and IL-13-producing CD4+ T cells from patients with AD were significantly higher than those from healthy control subjects (IL-4:3.9 ± 2.1% vs. 1.6 ± 0.7%, P = 0.0005, IL-13:4.0 ± 2.1% vs. 1.8 ± 0.8%, P = 0.0023), whereas the frequencies of IL-2- and IFN-γ-producing CD4+ T cells were significantly decreased in AD patients (IL-2:38.1 ± 10.3% vs. 51.3 ± 6.3%, P = 0.0003, IFN-γ: 9.9 ± 3.5% vs. 26.4 ± 4.6%, P 〈 0.0001). The percentage of CCR4+ cells in CD4+ CD45RO+ T cells in AD patients was significantly higher than that in healthy control subjects (24.4 ± 8.0% vs. 10.9 ± 2.3%, P 〈 0.0001) and was correlated positively with the total serum IgE, serum lactic dehydrogenase (LDH) level, eosinophil number, eruption score, and IL-4 and IL-13 secretion in CD4+ T cells, and inversely with IL-2 and IFN-γ secretion in CD4+ T cells. In contrast, CCR3 was not detected on circulating CD4+ T cells even in AD patients. On the other hand, the percentage of CCR5+ or CXCR3+ cells in CD4+ CD45RO+ T cells in AD patients was significantly decreased (CCR5:23.2 ± 7.0% vs. 28.4 ± 5.4%, P = 0.023, CXCR3:29.9 ± 11.4% vs. 38.5 ± 6.7%, P = 0.028) and was positively correlated with eruption score (P 〈 0.05). Multiple regression analyses showed that the percentage of CCR4 expression highly correlated with serum IgE, LDH, eosinophil number and eruption in AD patients.Conclusion CCR4+ cells might be involved in the aetiopathogenesis of AD.

    Instabilities and vortex dynamics in shear flow of magnetized plasmas (1991)
    New York, NY : American Institute of Physics (AIP)
    Physics of Fluids 3 (1991), S. 938-954

    Notes: Gradient-driven instabilities and the subsequent nonlinear evolution of generated vortices in sheared E×B flows are investigated for magnetized plasmas with and without gravity (magnetic curvature) and magnetic shear by using theory and implicit particle simulations. In the linear eigenmode analysis, the instabilities considered are the Kelvin–Helmholtz (K–H) instability and the resistive interchange instability. The presence of the shear flow can stabilize these instabilities. The dynamics of the K–H instability and the vortex dynamics can be uniformly described by the initial flow pattern with a vorticity localization parameter ε. The observed growth of the K–H modes is exponential in time for linearly unstable modes, secular for the marginal mode, and absent until driven nonlinearly for linearly stable modes. The distance between two vortex centers experiences rapid merging while the angle θ between the axis of the vortices and the external shear flow increases. These vortices proceed toward their overall coalescence, while shedding small-scale vortices and waves. The main features of vortex dynamics, the nonlinear coalescence and the tilt or the rotational instabilities of vortices, are shown to be given by using a low-dimension Hamiltonian representation for interacting vortex cores in the shear flow.

    Kelvin–Helmholtz instability and vortices in magnetized plasma (1987)

    Notes: Analytic theory and implicit particle simulations are used to describe the evolution of the Kelvin–Helmholtz instability and the plasma vortices driven by a nonuniform E×B flow velocity. Formulas for plasma convection arising from the self-consistent plasma electric field give the rate of anomalous momentum transport across the magnetic field. The momentum transport is shown to be controlled by the tilting angle of the elliptical vortex with respect to the direction of the parallel flow. Three stages of evolution are investigated and formulas for the final vortex state are given.

    Spatial structure of particle-orbit loss regions in l=2 helical systems (1990)

    Notes: Particle orbits and loss regions in both configuration and velocity spaces are studied on the basis of adiabatic invariants and guiding-center drift equations. The boundary of the loss region in the pitch angle major radius plane (χ0-ρ) is determined from the condition of whether the drift surfaces for helically trapped and transition particles hit the limiter or not. Two typical loss boundaries on the χ0-ρ plane are obtained. One determines the boundary of absolute confinement where no particles are lost. The other gives the boundary of the confined region of deeply trapped particles with v(parallel)=0. An analytical form describing the latter boundary is also derived. Effects of ripple modulation and electrostatic potential on these loss boundaries are discussed for the improvement of particle confinement.

    Notes: An analytic formula is derived for the loss cone in toroidal helical systems. Particular emphasis is put on the loss region for the particles that are barely trapped in the helical ripples. Effects of the radial electric field and shifts of the magnetic axis are discussed. Comparison with the numerical calculation confirms that the simple analytic formula gives good approximations.
