Transversity generalized parton distributions for the deuteron [PDF]
, 2018 28 pages, 13 figuresInternational audienceTransversity generalized parton distributions (GPDs) appear as scalar functions in the decomposition of off-forward quark-quark and gluon-gluon correlators with a parton helicity flip.

Generalized parton distributions of the photon [PDF]
, 2011 We present a first calculation of the generalized parton distributions of the photon (both polarized and unpolarized) using overlaps of light-front wave functions at leading order in α and zeroth order in αs; for non-zero transverse momentum transfer and

Physics Letters BWe investigate the twist-2 unpolarized generalized parton distributions (GPDs) of quarks for an on-shell gluon target in quantum chromodynamics. These GPDs parametrize the leading-twist matrix elements of the nonlocal light-like flavor-singlet vector ...

Structure and spin of the nucleon
EPJ Web of Conferences, 2014 Parton distribution functions, describing longitudinal momentum, helicity and transversity distributions of quarks and gluons, have been recently generalized to account also for transverse degrees of freedom.

Journal of Fish Biology, Volume 108, Issue 6, Page 2053-2068, June 2026.Abstract Ginglymostoma cirratum, commonly known as the nurse shark, is a nocturnally active benthic shark, often found in western and eastern Atlantic waters. Although this shark has been well explored in many biological aspects, few studies have thoroughly examined the morphology of its dermal denticles (or placoid scales).

Probing Spin Dependent Quark and Gluon Distributions Through Azimuthal and Polarization Asymmetries
EPJ Web of Conferences, 2016 Spin and transverse momentum dependent parton distributions - Generalized Parton Distributions, Transverse Momentum Distributions and related distributions - are at the interface between the QCD structure of the hadrons and observable quantities.

Generalized quasi parton distributions in a diquark spectator model
Physics Letters B, 2019 Recently the concept of quasi parton distributions (quasi-PDFs) for hadrons has been proposed. Quasi-PDFs are defined through spatial correlation functions and as such can be computed numerically using quantum chromodynamics on a four-dimensional lattice.

A Stochastic Approach to Quantifying the Propagation of Uncertainty in Soil Organic Carbon Content
Journal of Plant Nutrition and Soil Science, Volume 189, Issue 1, Page 117-130, February 2026.ABSTRACT Background Precision agriculture (PA) is a site‐specific management approach that utilises spatiotemporal information to improve productivity while also promoting sustainability. Accurate estimates of soil properties, along with the uncertainty of these estimates, are necessary for decision‐making in PA.

Chiral odd generalized parton distributions from exclusive πo electroproduction [PDF]
, 2013 Exclusive pseudoscalar meson electroproduction in the multi-GeV region was recently proposed as a way to obtain chiral odd generalized parton distributions from data.

Generalized parton distributions from neutrino experiments: twist-three effects
EPJ Web of Conferences, 2014 We study the twist-3 corrections to the neutrino induced deeply virtual meson production due to the chiral odd transversity Generalized Parton Distribution (GPD).
