AIP Conference Proceedings, 2010 A one-parameter conformal invariance of Maxwell's equations allows the wavelengths of electromagnetic waves to change as they propagate, and do so even in otherwise field-free space. This produces an ambiguity in interpretations of stellar red shifts.

Cosmology and the massive photon frequency shift in the Standard-Model Extension
European Physical Journal C: Particles and Fields, 2021 The total red shift z might be recast as a combination of the expansion red shift and a static shift due to the energy–momentum tensor non-conservation of a photon propagating through Electro-Magnetic (EM) fields.

Proton transport model in the ionosphere. 2. Influence of magnetic mirroring and collisions on the angular redistribution in a proton beam [PDF]
Annales Geophysicae, 1998 We investigate the influence of magnetic mirroring and elastic and inelastic scattering on the angular redistribution in a proton/hydrogen beam by using a transport code in comparison with observations.

New ScientistThis paper evokes the dynamic colour space that results when a printed colour (subtractive) interacts with colour from video projection (additive). Colour shapes our knowledge and adds mystery to our world as light and pigmented surfaces interrelate. In our recent work, Breath, we present a richly layered mural-sized print along with video projection ...

Political risks: the “red shift” in debt sustainability analysis [PDF]
Risk Management Magazine, 2020 Political stability and economic policy uncertainty can be key determinants of sovereign debt dynamics, and we show how they can be incorporated in debt sustainability analysis.
