purpose: neuromyelitis opitca (nmo) is an autoimmune disease that relates to deposition of anti-aquaporin-4 (aqp4) igg in the central nervous system (cns). however, called seronegative nmo when patients are negative for aqp4 antibody. nevertheless, nmo is most probably an antibody mediated disease. the aim of this study was to assess the association between seronegative nmo disease and variatio...

Problem Statement: In MIMO system, capacity mainly depends on the channel and the antenna characteristics. The capacity can be improved by proper design of antenna elements and choosing appropriate array configuration and the directive elements give more capacity than omni directional elements. The dual polarized antennas are better than single polarized antennas as the former can provide two i...

 We study the origin of subharmonic synchronization in arrays consisting of few over-damped Josephson junctions. We show that for asymmetric arrays, the evolution equations contain second (or higher) order derivatives or non-sinusoidal terms, both leading to fractional Shapiro steps in presence of external ac drive .

Free rotating impurity-vacancy (IV) dipoles in an alkali halide matrix are polarized to the extent of 1/3 of the total number of IV dipoles. An experimental procedure is suggested in this article which will help in the polarization of IV dipoles to the extent of 2/3 of the total number of IV dipoles. In the suggested experimental procedure, the electric field will be applied at first in one dir...

Abstract An approach is presented for modelling the noise propagation beneath train floor and this applied to rolling sources. It assumed that sound incident on made up of a direct reverberant component. A combination two numerical approaches considered deal with these: an equivalent source model, represent component, statistical energy analysis (SEA) part. In wheel replaced by monopole dipole ...

We investigate the spatial decay and temporal localization properties of quasimodes (i.e., scattering resonances) two-dimensional Vogel spirals, composed deterministic, aperiodic arrays electric dipoles. By determining structural entropy maps spirals using Green's matrix method, we show that three distinctive types coexist in spirals: exponential, power law, Gaussian. While exponential power-la...

In proposals for quantum computers using arrays of trapped ultracold polar molecules as qubits, a strong external field with appreciable gradient is imposed in order to prevent quenching of the dipole moments by rotation and to distinguish among the qubit sites. That field induces the molecular dipoles to undergo pendular oscillations, which markedly affect the qubit states and the dipole-dipol...

The Iranian Light Source Facility (ILSF) is a new 3 GeV third generation synchrotron light source which is consisted of several pre-accelerators and a storage ring with the beam current of 400 mA. Based on the main lattice candidate, the storage ring includes of 100 dipoles, 320 quadrupoles and 320 sextupole magnets. To develop fabrication procedures and techniques and to compare the measuremen...

Mostly forsaken, but revived after the emergence of all-dielectric nanophotonics, Kerker effect can be observed in a variety nanostructures from high-index constituents with strong electric and magnetic Mie resonances. A necessary requirement for existence response limits use generally nonmagnetic conventional plasmonic effect. In spite this, we demonstrate here lattice regular Al nanostructure...
