Query: Nucleon Charges and Sigma Terms from $N_{f}=2+1$ QCD   We report on recent progress of our analysis of the nucleon sigma terms, as
well as the singlet scalar, axial and tensor nucleon charges. These are
determined employing the CLS gauge ensembles, which are generated using the
L\"uscher-Weisz gluon action and the non-perturbatively improved
Sheikholeslami-Wohlert fermion action with $N_{f}=2+1$ dynamical fermions. For
the ensembles analysed thus far, the pion masses range from 200 MeV up to 410
MeV, and the lattice spacings take five values between 0.09~fm and 0.04~fm. We
have employed a variety of methods to determine the relevant correlation
functions, including the sequential source method for connected contributions
and the truncated solver method for disconnected contributions.
