      abstract     = {We present a QCD calculation of the u, d, and s scalar
                      quark contents of nucleons based on 47 lattice ensembles
                      with Nf=2+1 dynamical sea quarks, 5 lattice spacings down to
                      0.054 fm, lattice sizes up to 6 fm, and pion masses down to
                      120 MeV. Using the Feynman-Hellmann theorem, we obtain
                      fNud=0.0405(40)(35) and fNs=0.113(45)(40), which translates
                      into σπN=38(3)(3)  MeV, σsN=105(41)(37)  MeV, and
                      yN=0.20(8)(8) for the sigma terms and the related ratio,
                      where the first errors are statistical and the second errors
                      are systematic. Using isospin relations, we also compute the
                      individual up and down quark contents of the proton and
                      neutron (results in the main text).},
