In recent years there has been much discussion of the difference between inequality and polarisation. The vast literature on inequality is held to miss out key features of distributional change, which are better described as changes in polarisation. Axioms have been proposed which capture some of these differences, and measures of polarisation, as distinct from inequality, have been suggested. ...

We have used the University of Tasmania Mt Pleasant 26-m radio telescope to investigate the polarisation characteristics of a sample of strong 6.7GHz methanol masers, the first spectral line polarisation observations to be undertaken with this instrument. As part of this process we have developed a new technique for calibrating linear polarisation spectral line observations. This calibration me...

The complex Kohn variational principle and the (correlated) hyperspherical harmonics method are applied to study the proton–deuteron elastic scattering at energies above the deuteron breakup threshold. Results for the elastic cross section and various elastic polarization observables have been obtained by taking into account the long–range effect of the Coulomb interaction and using a realistic...

The advantages to study charge–symmetry breaking and especially the phenomenon of f0 −a0 mixing in nucleon–nucleon and deuteron–deuteron induced reactions are discussed.

We present the rst imaging circular polarimetry of the Orion Molecular Cloud, OMC-1. The observations, taken in the J , H , K n and nbL bands, reveal a complex pattern of circular polarisation. Globally, there is a background circular polarisation of the order of 2 percent in the K n band, conforming to the typical quadrupolar patterns that have been observed in other outtow sources. Overlaying...

An overview is given of some recent and planned experiments which have or will substantially increase our knowledge of the electromagnetic properties of the few body systems. Specific examples include the proton and neutron elastic form factors, the deuteron elastic form factors, deuteron threshold electro-disintigration and quasi-elastic scattering, deuteron photodisintigration, and finally me...

The excited-state deuteron transfer (ESDT) of deuterated 7-hydroxyquinoline (7DQ) along a heterogeneous hydrogen (H)-bonded chain composed of two deuterated alcohol (ROD) molecules having different acidities, as a model system of a proton wire consisting of diverse amino acids, has been investigated. To understand dynamic differences between deuteron transfer and proton transfer, solvent-invent...

We report the first demonstration of polarisation insensitive all-optical wavelength conversion (AOWC) for single wavelength channel 640 Gbit/s return-to-zero differential-phase-shift-keying (RZ-DPSK) signal and 1.28 Tbit/s polarisation multiplexed (Pol-Mux) RZ-DPSK signals using a 100-m polarisation-maintaining highly nonlinear fiber (PM-HNLF) in a polarisation diversity loop configuration.
