International Journal of Electrochemical Science, 2015 Cerium-doped terbium-lutetium aluminum garnet ((TbxLu1-x)2.9Al5O12: 0.1Ce) were synthesized by solid state reaction method. The crystalline phase, morphology and photoluminescence properties were characterized by using X-ray diffraction (XRD ...

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.

Electro-absorption of silicene and bilayer graphene quantum dots [PDF]
, 2016 We study numerically the optical properties of low-buckled silicene and AB-stacked bilayer graphene quantum dots subjected to an external electric field, which is normal to their surface.

More complete discussion of the time-dependence of the non-static line element for the universe [PDF]
, 1930 In a previous article,(1) I have shown that a continuous transformation of matter into radiation, occurring throughout the universe, as postulated by the astrophysicists, would necessitate a nonstatic line element for the universe, and have shown that ...

Neutrinos produced by ultrahigh-energy photons at high red shift [PDF]
, 2000 Some of the proposed explanations for the origin of ultrahigh-energy cosmic rays invoke new sources of energetic photons (e.g., topological defects, relic particles, etc.).

Spectral Red-Shift Versus Broadening from Photon and Dilepton Spectra [PDF]
, 2001 We estimate the photon and dilepton emission rates from hot hadronic matter with in-medium spectral shift and broadening of vector mesons. It is observed that both the WA98 photon data and CERES/NA45 dilepton data can be well reproduced with similar ...
