  Nucleon isovector vector- and axialvector-current form factors, the
renormalized isovector transversity and scalar charge, and the bare quark
momentum and helicity moments of isovector structure functions are reported
with improved statistics from two recent RBC+UKQCD 2+1-flavor dynamical
domain-wall fermions ensembles: Iwasaki\(\times\)DSDR gauge \(32^3\times64\) at
inverse lattice spacing of 1.38 GeV and pion mass of 249 and 172 MeV.
