Screening High-z GRBs with BAT Prompt Emission Properties [PDF]
, 2008 Detecting high-z GRBs is important for constraining the GRB formation rate, and tracing the history of re-ionization and metallicity of the universe.

Photon Redshift in a Magnetic field
, 2010 Previous results from the authors concerning the arising a tiny photon anomalous paramagnetic moment are also interpreted as a red-shift in analogy to the gravitational known effect.

Low red-shift effects of local structure on the Hubble parameter in presence of a cosmological constant [PDF]
, 2016 In order to estimate the effects of local structure on the Hubble parameter we calculate the low-redshift expansion for $H(z)$ and $\frac{\delta H}{H}$ for an observer at the center of a spherically symmetric matter distribution in presence of a ...

Spectral Shifts of Nonadiabatic High-Order Harmonic Generation
Applied Sciences, 2013 High-order harmonic generation (HHG) is a nonlinear nonperturbative process in ultrashort intense laser-matter interaction. It is the main source of coherent attosecond (1 as = 10−18 s) laser pulses to investigate ultrafast electron dynamics.

Influence of disorder and a parallel magnetic field on a Quantum Cascade Laser
, 2000 The luminescence spectra of a quantum cascade laser in a strong magnetic field is influenced significantly by the presence of disorder (charged or neutral) in the system.

Effects of urea on activity and conformation of acid phosphatase from wheat germ
浙江大学学报. 农业与生命科学版, 2004 Changes in conformation and activity of acid phosphatase from wheat germ following denaturation of the enzyme by urea solutions of different concentrations were measured by the shift in fluorescence and differential UV-absorption spectrum.

Proposal for an Optical Test of the Einstein Equivalence Principle
, 2019 The Einstein Equivalence Principle (EEP) underpins all metric theories of gravity. Its key element is the local position invariance of non-gravitational experiments, which entails the gravitational red-shift.
