Abstract: We present the first chiral-continuum extrapolated up, down and strange quark spin contribution to the proton spin using lattice QCD. For the connected contributions, we use eleven ensembles of 2+1+1-flavor of Highly Improved Staggered Quarks… read more here.

Abstract: A computer model was used to simulate the dependence of protonmotive force (Δp), proton leak and phenomenological (involving proton leak) ATP/O2 ratio on work intensity in skeletal muscle. Δp, NADH and proton leak decreased with… read more here.
