Associations Between Perceived Societal Polarisation and (Extreme) Non‐Normative Attitudes and Behaviour

Social Inclusion
Perceptions of societal polarisation in a country may influence individuals’ willingness to engage in non(normative) collective action. In the present research, we test the hypothesis that perceived societal polarisation reduces trust in the government ...

New constraints on very light pseudoscalars [PDF]

, 2011
Nearly massless axion-like particles are of interest for astrophysical observations, and some constraints on their parameter space do exist in the literature.

Full-Stokes, Multi-Frequency Radio Polarimetry of Fermi Blazars; Monitoring and Modelling

Galaxies, 2017
The polarised emission from active galactic nuclei (AGN) jets carries information about the physical conditions at the emitting plasma elements, while its temporal evolution probes the physical processes that introduce variability and dynamically modify ...

Statistics of the fractional polarisation of extragalactic dusty sources in Planck HFI maps

, 2017
We estimate the average fractional polarisation at 143, 217 and 353 GHz of a sample of 4697 extragalactic dusty sources by applying stacking technique. The sample is selected from the second version of the Planck Catalogue of Compact Sources at 857 GHz ...

Evolution of the Polarizing Effect of $\text{MoS}_{2}$

IEEE Photonics Journal, 2015
We have explored the polarization behavior of MoS2 at three different wavelengths using a polymer-based waveguide. The MoS2-coated waveguide has been fabricated based on the drop casting method.

Polarised infrared emission from X-ray binary jets

, 2008
Near-infrared (NIR) and optical polarimetric observations of a selection of X-ray binaries are presented. The targets were observed using the Very Large Telescope and the United Kingdom Infrared Telescope.

``Faster than Light'' Photons in Gravitational Fields -- Causality, Anomalies and Horizons [PDF]

, 1995
A number of general issues relating to superluminal photon propagation in gravitational fields are explored. The possibility of superluminal, yet causal, photon propagation arises because of Equivalence Principle violating interactions induced by vacuum ...

Suboptimum adative polarisation cancellers for dual-polarisation radars

IEE Proceedings F Communications, Radar and Signal Processing, 1988
In the paper some suboptimum adaptive polarisation techniques for the cancellation of partially polarised disturbances are analysed. They are based on suitable use of the estimates of the crosscorrelation between the dual-polarisation received signals.

Prospect of polarisation measurements from black hole binaries in their thermal state with a scattering polarimeter

, 2011
X-ray polarisation measurement is a unique tool which may provide crucial information regarding the emission mechanism and the geometry of various astrophysical sources, like neutron stars, accreting black holes, pulsar wind nebulae, AGNs, Supernova ...
