Parton distributions from lattice data: the nonsinglet case
Journal of High Energy Physics, 2019 We revise the relation between Parton Distribution Functions (PDFs) and matrix elements computable from lattice QCD, focusing on the quasi-Parton Distribution Functions (qPDFs) approach.

Agronomy Journal, Volume 118, Issue 4, July/August 2026.Abstract Soil organic carbon (SOC) dynamics and greenhouse gas (GHG) emissions in dry (arid and semi‐arid) agroecosystems are regulated by low and variable moisture, episodic wet–dry cycles, and limited organic inputs. Although process‐based biogeochemical models are widely used to quantify these processes, a comprehensive assessment of their ...

Double D-meson production in proton-proton and proton-lead collisions at the LHC
Physics Letters B, 2020 We consider the simultaneous production of two heavy-flavoured hadrons – particularly D mesons – at the LHC. We base our calculations on collinearly factorized QCD at next-to-leading order, using the contemporary parton distribution functions and D-meson

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.ABSTRACT Climate vulnerability in sharks and rays is unevenly distributed across habitats and ecological groups, reflecting differences in exposure pathways and biological constraints. Using an updated application of the Integrated Risk Assessment for Climate Change (IRACC) framework, we conducted a global reassessment of climate vulnerability for 95 ...

Polarized parton densities and spin dependent structure function of the nucleon
EPJ Web of Conferences, 2017 We study the polarized parton distribution functions (PPDFs) from recent experimental data at the next-to-leading order (NLO) approximation in the fixed-flavor number scheme.

A Novel Sequential Monte Carlo Algorithm for Parameter Estimation in Eco‐Hydrological Models
Water Resources Research, Volume 62, Issue 7, July 2026.Abstract Bayesian inference offers a flexible framework for parameter estimation and uncertainty quantification in eco‐hydrological models. However, simultaneously achieving robust posterior exploration and high computational efficiency for multimodal, high‐dimensional, and computationally intensive targets remains challenging for the widely used ...

Flavor hierarchy of parton energy loss in quark-gluon plasma from a Bayesian analysis
Physics Letters BThe quenching of light and heavy flavor hadrons in relativistic heavy-ion collisions probes the color and flavor dependences of parton energy loss through a color-deconfined quark-gluon plasma (QGP), and thus offers an important test of QCD-based ...

Non-universality of transverse momentum dependent parton distribution functions [PDF]
, 2008 In the field theoretical description of hadronic scattering processes, single transverse-spin asymmetries arise due to gluon initial and final state interactions.
