The solar red-shift

open access: yes, 1961
Shortly after Rowland's fundamental study of the wavelengths of Fraunhofer lines, Jewell in 1896 observed that the solar wavelengths were shifted to the red side of the corresponding wavelengths observed in the laboratory. This shift became known as the red shift of solar lines, and at first led to various erroneous concepts of conditions in the solar ...

Red Shift: Procedural Shift-Reduce Parsing

open access: yes, 2017
Red Shift is a new design pattern for implementing parsers. The pattern draws ideas from traditional shift-reduce parsing as well as procedural PEG parsers. Red Shift parsers behaves like shift-reduce parsers, but eliminate ambiguity by always prioritizing reductions over shifts. To compensate the resulting lack of expressivity, reducers are not simple

Investigation into the Photoluminescence Red Shift in Cesium Lead Bromide Nanocrystal Superlattices. [PDF]

open access: yesJ Phys Chem Lett, 2019
The formation of cesium lead bromide (CsPbBr3) nanocrystal superlattices (NC SLs) is accompanied by a red shift in the NC photoluminescence (PL). The values of the PL red shift reported in the literature range from none to ∼100 meV without unifying ...

Purification and Characterisation of Two Novel Pigment Proteins from the Carapace of Red Swamp Crayfish (Procambarus clarkii)

open access: yesFoods, 2021
Pigment proteins play a vital role in the red colour change of the red swamp crayfish (Procambarus clarkii) shell after cooking. In this study, two red-change-related pigment proteins with molecular weights of approximately 170 and 43 kDa—denoted as F1 ...

Cosmology and the massive photon frequency shift in the Standard-Model Extension

open access: yesEuropean 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.

Enantioselective Recognition of Lysine and Phenylalanine Using an Imidazole Salt-Type Fluorescent Probe Based on H8-BINOL

open access: yesMolecules, 2022
An imidazole bromide fluorescent probe (R)-1 based on chiral H8-BINOL was synthesized with a high yield; it was found to have good enantioselective recognition of lysine and phenylalanine using fluorescence analysis.

Proton transport model in the ionosphere. 2. Influence of magnetic mirroring and collisions on the angular redistribution in a proton beam [PDF]

open access: yesAnnales 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.

Crystallographic and optical studies on Cr doped ZnS nanocrystals

open access: yesCerâmica, 2014
Chromium doped ZnS nanocrystals with pure and 10% compositions were synthesized by chemical co-precipitation route. Samples were characterized by X-ray diffraction (XRD) technique, Fourier transforms infrared spectroscopy (FTIR) and UV-Visible ...

Red shift

open access: yesNew Scientist
This 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 ...
