Measurement of jet-substructure observables in top quark, W boson and light jet production in proton-proton collisions at s $$ sqrt{s} $$ = 13 TeV with the ATLAS detector

Abstract A measurement of jet substructure observables is presented using data collected in 2016 by the ATLAS experiment at the LHC with proton-proton collisions at s $$ sqrt{s} $$ = 13 TeV.Large-radius jets groomed with the trimming and soft-drop algorithms are studied.Dedicated event selections are used to study jets produced by light quarks or g

Changes within the P681 residue of spike dictate cell fusion and syncytia formation of Delta and Omicron variants of SARS-CoV-2 with no effects on neutralization or infectivity

The rapid spread and dominance of the Omicron SARS-CoV-2 lineages have posed severe health challenges worldwide.While extensive research on the role of the Receptor Binding Domain (RBD) in promoting viral infectivity and vaccine sensitivity has been well documented, the functional significance of the 681PRRAR/SV687 polybasic motif of the viral spik
