A scalar variational analysis based on a Gaussian approximation of the fundamental mode of a double-clad elliptical fiber with a depressed inner cladding is studied. The polarization properties and graphic results are presented; they are given in terms of three parameters: the ratio of the major axis to the minor axis of the core, the ratio of the inner cladding major axis to the core major axi...

Abstaact-Mercier’s localized perturbation criterion near the magnetic axis is examhied for a particular type of toroidal configuration of non-planar magnetic axis of variable curvature and torsion with non-circular (elliptically and triangularly deformed) plasma cross section for the ‘resonance case’. As an application, a numerical calculation is carried out for a class of equilibria that belon...

A recent observational result finds that the quenching of satellites in groups at $z=0.08$ has an angular dependence relative to semi-major axis central galaxy. This observation is described as `anisotropic quenching' or `angular conformity'. In this paper I study variation colour a mass limited sample satellite galaxies their angle from major Brightest Cluster Galaxy CLASH clusters up $z\sim0....

This work focuses on the dynamical rotatory motion of an asymmetric rigid body (RB) subjected to a constant body-fixed torque and vector gyrostatic moment (GM). The is considered in absence first two components GM. novelty current conversion stability analysis this from dimensional phase plane three ones space. Specifically, scenarios stationary torques are considered, one directed minor or maj...

In an induction linac [1] a toroidal solenoid magnet carries a time-dependent current I(t) such that the induced electric field can transfer energy from the magnet to charged particles that move along the axis of the toroid. Discuss the force and momentum balance in an idealized induction linac consisting of a single magnet whose form is a torus of major radius a and minor radius b a, and a sin...

A mechanical strain field applied to a monodomain cholesteric elastomer will unwind the helical director distribution. There are similarities with the classical problem of an electric field applied to a cholesteric liquid crystal but also differences. Frank elasticity is of minor importance unless the gel is very weak. The interplay is between the director being helically anchored to the rubber...
