We describe a recent lattice-QCD calculation of the leptonic decay constantsof heavy-light pseudoscalar mesons containing charm and bottom quarks and ofthe masses of the up, down, strange, charm, and bottom quarks. Results forthese quantities are of the highest precision to date. Calculations use 24isospin-symmetric ensembles of gauge-field configurations with six differentlattice spacings as small as approximately 0.03 fm and several values of thelight quark masses down to physical values of the average up- anddown-sea-quark masses. We use the highly-improved staggered quark (HISQ)formulation for valence and sea quarks, including the bottom quark. Theanalysis employs heavy-quark effective theory (HQET). A novel HQET method isused in the determination of the quark masses.
