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 ...

Intrinsic bottom and its impact on heavy new physics at the LHC
EPJ Web of Conferences, 2016 Heavy quark parton distribution functions (PDFs) play an important role in several Standard Model and New Physics processes. Most analyses rely on the assumption that the charm and bottom PDFs are generated perturbatively by gluon splitting and do not ...

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 ...

Double parton distributions in the pion in the Nambu–Jona-Lasinio model
Journal of High Energy Physics, 2019 Two-parton correlations in the pion, a non perturbative information encoded in double parton distribution functions, are investigated in the Nambu–Jona-Lasinio model.

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 ...

Hadron structure beyond collinear level and precision DIS measurements
EPJ Web of Conferences, 2015 General formulations of QCD factorization for hadronic collisions extend the notion of ordinary parton distributions to transverse-momentum dependent (TMD) parton density and parton decay functions.

The Price Gap in Agriculture‐Based Greenhouse Gas Offset Markets
Australian Journal of Agricultural and Resource Economics, Volume 70, Issue 3, Page 610-624, July 2026.ABSTRACT Today, there is a global effort to reduce greenhouse gas net emissions (GHGNE). For economic well‐being, it is important to identify low‐cost means of net emission offsets. Agriculture and forestry have received considerable attention as a means of supplying emissions offsets, as they contribute nearly 20% of global emissions.

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

Update of MRST Parton Distributions
, 2002 I present a brief summary of the most important updates in the MRST determinations of the NLO and NNLO parton distributions. I concentrate on uncertainties due to input assumptions and possible theoretical corrections, particularly isospin violation, QED corrections, NNLO and corrections at low Q^2 and small x.

Extracting Mellin moments of double parton distributions from lattice data
Journal of High Energy PhysicsReconstructing Mellin moments of double parton distributions from calculations on a Euclidean lattice requires taking an integral over a variable that may be regarded as a Ioffe time.
