A novel determination of non-perturbative contributions to Bjorken sum rule
TL;DR: Based on the accurate pQCD prediction of BSR, a novel fit of the nonperturbative high-twist contributions by comparing with JLab data was given in this article, where the PMC prediction satisfies the standard renormalization group invariance, e.g. its fixed-order prediction does scheme-and-scale independent.

Structure functions at low Q2: higher twists and target mass effects
TL;DR: In this article, the physics of structure functions at low Q 2, focusing on the phenomenon of quark-hadron duality and the resonance scaling transition, were reviewed and a new implementation of target mass corrections to nucleon structure functions was presented.

TL;DR: In this article , the quarkonic O(αs2) massive operator matrix elements for the twist-2 operators and the associated heavy flavor Wilson coefficients in polarized deeply inelastic scattering in the region Q2≫m2 to O(ε) in the case of the inclusive heavy flavor contributions were calculated in terms of harmonic sums.

Bjorken sum rule with hyperasymptotic precision
TL;DR: In this article , an improved determination of the normalization of the leading infrared renormalon of the Bjorken sum rule was obtained by including the leading terminant associated with the first infrared renormon.

Non-Lagrangian Models of Current Algebra
TL;DR: In this article, an alternative to specific Lagrangian models of current algebra is proposed, in which scale invariance is a broken symmetry of strong interactions, as proposed by Kastrup and Mack.

Theory of Functions
TL;DR: In this paper, the authors pointed out that the distinction between "finite" and "infinite" is one which does not require definition, and that the authors' view is not the only accepted view.

High-energy electroproduction and the constitution of the electric current
TL;DR: In this article, the asymptotic behavior of electroproduction cross sections is shown to contain information about the constitution of the electric current, and it is shown that the cross sections are a good indicator of the strength of electric currents.

Positivity constraints for anomalous dimensions

TL;DR: Wilson's operator product expansion is examined in this article, where it is shown how to project on operators of definite spin at finite Q2 consistency conditions for anomalous dimensions following from positivity using the moment problem.
