Polarised stereoscopic projection involves the polarisation of the two projected images in orthogonal directions e.g. +/45 degrees for linear polarisation, or clockwise and counter-clockwise for circular polarisation. When LCD projectors are used for polarised stereoscopic projection it is important to take into consideration the fact that the output of these types of projectors is already pola...

Model polarisation potentials for use in calculating positron-molecule cross sections are often based on approximations in which terms that depend on the sign of the charge of the projectile are neglected. Thus, these potentials do not fully distinguish between electron and positron scattering. The validity of using such potentials for positronH2 collisions is investigated by performing scatter...

We have analysed the angular power spectra of the Parkes radio continuum and polarisation survey of the Southern galactic plane at 2.4 GHz. We have found that in the multipole range l = 40–250 the angular power spectrum of the polarised intensity is well described by a power-law spectrum with fitted spectral index αL = 2.37 ± 0.21. In the same multipole range the angular power spectra of the E ...

In this paper, we determine the magnetic moment induced in graphene when grown on a cobalt film using polarised neutron reflectivity (PNR). A signal was detected by X-ray circular dichroism (XMCD) spectra at C K-edge. From XMCD sum rules an estimated of 0.3 μB/C atom, while more accurate estimation 0.49 atom obtained carrying out PNR measurement 300 K. The results indicate that higher Co is cou...

We report a study in which Andreev reflection using a Nb point contact is used to measure the transport spin polarisation of the 4d itinerant ferromagnet SrRuO3. By performing the study in high quality thin films with residual resistivities less than 7μΩ-cm, we ensure that the study is done in the ballistic limit, a regime which is difficult to reach in oxide ferromagnets. The degree of transpo...

Planar polarity describes the coordinated polarisation of cells or structures in the plane of a tissue. The patterning mechanisms that underlie planar polarity are well characterised in Drosophila, where many events are regulated by two pathways: the 'core' planar polarity complex and the Fat/Dachsous system. Components of both pathways also function in vertebrates and are implicated in diverse...

We propose a new method for dynamic nuclear polarisation in a quasi one-dimensional quantum wire utilising the spin-orbit interaction, the hyperfine interaction, and a finite sourcedrain potential difference. In contrast with current methods, our scheme does not rely on external magnetic or optical sources which makes independent control of closely placed devices much more feasible. Using this ...

The article focuses on the principles of strong concentration polarisation of flat and curved interfaces including the phenomenon of the limiting current. It is shown both theoretically and experimentally that electroosmosis of the second kind near the curved interface causes an important change of characteristics of concentration polarisation and a rapid growth of the current through an interf...

The photoelectrons emitted by lead atoms exposed to circularly-polarised vuv radiation are partially spin polarised. Unlike the photoionisation cross section, the measured polarisation does not show autoionisation resonances as a function of wavelength. The polarisation and the known cross section results together yield new absorption data, which can be compared with the oscillator strengths of...
