µ -symmetry and µ -conservation law for the extended mKdV equation

Order reduction and μ-conservation law for the non-isospectral KdV type equation a with variable-coefficients

The goal of this paper is to calculate of order reduction of the KdV typeequation and the non-isospectral KdV type equation using the μ-symmetrymethod. Moreover we obtain μ-conservation law of the non-isospectral KdVtype equation using the variational problem method.

R Symmetry and the μ Problem

A natural origin for the μ and μB parameters of weak scale supersymmetric theories is proposed, applicable to any supersymmetry breaking messenger scale between the weak and Planck scales. Although quite general, it requires supersymmetric interactions to respect an R symmetry with definite quantum numbers, and it requires some new scale of symmetry breaking. The required R symmetry distinguish...

The Crab Nebula at 850 Μ Μ Μ Μ Μm

Observations of the Crab Nebula at 850 µm made with the Submillimetre Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope are presented. A variety of chop-throws and scanning directions was used in these observations, to well sample structure over a range of scales and directions. The resulting image, which was restored using a MEM algorithm, has a resolution of 17 arcsec, ...
