In Jiang et al. (2020), we reported a possible bright flash (hereafter GN-z11-flash) from a galaxy GN-z11 at z ≈ 11. Recently, Steinhardt et al. (2021; arXiv:2101.12738) found 27 images with transient signals in Keck MOSFIRE archival data and claimed that GN-z11-flash was more likely from a moving object in our Solar system. We show that the Steinhardt et al.’s definition of the chance probability and their methodology of finding GN-z11-flash-like transients are problematic in several aspects…

The GN-z11-Flash Event can be a Satellite Glint
Recently Jiang et al. reported the discovery of a possible short duration transient, detected in a single image, spatially associated with a z ∼ 11 galaxy. Jiang et al. and Kann et al. suggested the
GN-z11-flash was a signal from a man-made satellite not a gamma-ray burst at redshift 11
Long gamma-ray bursts (GRB), explosions of very massive stars, provide crucial information on stellar and galaxy evolution, even at redshifts z ~ 8 - 9.5, when the Universe was only 500-600 million
Application of DNA-Binding Protein Prediction Based on Graph Convolutional Network and Contact Map
TLDR
In this study, the features and structures of proteins were used to obtain their representations through graph convolutional networks and contact map to improve the speed and accuracy of DNA-binding protein recognition.
