                      fermion loops on Graphics Processing Units for a range of
                      nucleon matrix elements extracted using lattice QCD. The
                      isoscalar electromagnetic and axial vector form factors, the
                      sigma-terms and the momentum fraction and helicity are among
                      the quantities we evaluate. We compare the disconnected
                      contributions to the connected ones and give the physical
                      implications on nucleon observables that probe its
                      structure.},
