We extract the individual contributions from u and d quarks to the Dirac and Pauli form factors of the proton, after a critical examination of the available measurements of electromagnetic nucleon form factors. From this data we determine generalized parton distributions for valence quarks, assuming a particular form for their functional dependence. The result allows us to study various aspects of nucleon structure in the valence region. In particular, we evaluate Ji's sum rule and estimate the total angular momentum carried by valence quarks at the scale mu = 2 GeV to be J_v^u = 0.230 +0.009 -0.024 and J_v^d = -0.004 +0.010 -0.016.

Six-dimensional light-front Wigner distributions of the proton
All 16 leading-twist six-dimensional light-front quark Wigner distributions for the proton are computed in a spectator-diquark model, extending earlier five-dimensional and unpolarized-only results.

Implications of exclusive photon leptoproduction measurements for the proton charge-radius puzzle
After excluding or cutting low-|t| CLAS 2018 data, BH-dominated EP measurements yield a proton charge radius smaller than the PDG average and consistent with PRad and muonic hydrogen.

Mechanical properties of the nucleon from the generalized parton distributions
Using a double-distribution GPD model constrained by elastic-scattering data, the paper fits DQ(0) = -3.37 ± 0.17 from Compton form factors and derives proton pressure, shear, and radii.
