Previously, we reported two trigonal crystals of the PSD95‐ PDZ3 (PDB entries 6QJJ  and  6QJI),  where  Asp332  plays  a  central  role  in  the  interactions 

The main spectral feature in the spectrum is an intense absorption that a ffects the soft X-ray band. In particular, data show a variable WA, which is persistent over the years.

The detection of radio emission in Swift J0243.6+6124 (a high-mass neutron star binary) has also been interpreted as coming from a jet based on the correlation between X-ray and

The response of the synchronization circuit is shown in figure 7; where the upper trace corresponds to line L AC , and the lower trace is the voltage at the input of the VCO; as can
