Global Change Biology, Volume 32, Issue 7, July 2026.Expanding organic farming across the EU and UK could cut fertilizer use and improve some degraded soils, but comes with lower crop yields—driven largely by crop rotation shifts—and a modest decline in soil carbon. Increased use of nitrogen‐fixing cover crops could help maintain soil carbon and boost yields, but at the cost of greater nitrogen losses to

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.

Linking Plant and Microbial Traits to Soil Carbon for Reliable and Resilient Bioenergy Systems
GCB Bioenergy, Volume 18, Issue 7, July 2026.Plant–microbe–soil interactions supporting productivity and soil carbon storage in bioenergy systems. Plants supply organic inputs that sustain microbial communities driving nutrient cycling, carbon stabilization, and soil aggregation. These interactions enhance soil structure and nutrient retention, supporting both biomass productivity and broader ...

Proton structure and parton distribution functions from HERA
EPJ Web of Conferences, 2016 The H1 and ZEUS collaborations at the electron-proton collider HERA collected e± p scattering data corresponding to an integrated luminosity of about 1 fb−1.

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract The Arabian Peninsula encompasses one of the world's most extensive aeolian systems, yet the provenance and transport history of its dune sediments are not well understood. Using hyperspectral data from NASA's Earth Surface Mineral Dust Source Investigation (EMIT), we mapped mineral compositions and abundance patterns across dune fields and ...

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

Towards parton distribution functions with small-x resummation: HELL 2.0 [PDF]
, 2017 A bstractIn global fits of parton distribution functions (PDFs) a large fraction of data points, mostly from the HERA collider, lies in a region of x and Q2 that is sensitive to small-x logarithmic enhancements.
