Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition

Functional Ecology, Volume 40, Issue 8, Page 2548-2559, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Elevated tropospheric ozone (O3) and nitrogen (N) deposition are concurrent atmospheric changes that strongly influence terrestrial carbon cycling, yet their combined effects on below‐ground decomposition remain poorly understood.

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 ...

Multi‐Model Ensembles in Ecosystem Modeling: Challenges and Best Practices for Decision‐Making

Global Change Biology, Volume 32, Issue 8, August 2026.
As ecosystem models increasingly inform environmental policy, markets, and climate‐related investments, this article highlights a critical but often overlooked issue: combining multiple models does not automatically make predictions more reliable.

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.

Three Decades of Soil N2O Research—Insights and Gaps

Global Change Biology, Volume 32, Issue 8, August 2026.
Progress in N2O Research and Key Breakthroughs and Transitions from 1990 to 2025 across three domains: (A) process understanding, (B) microbial ecology, and (C) modelling of soil N2O emissions. ABSTRACT Nitrous oxide (N2O) is a potent greenhouse gas (GHG) whose atmospheric concentration continues to rise, largely driven by nitrogen (N) inputs to ...

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.

Simulating soil organic carbon and greenhouse gas emissions in dry regions: A review of the scope and limitations of biogeochemical models

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 ...

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.

Global Patterns and Drivers of Climate Vulnerability in Sharks and Rays: A Reassessment Using the IRACC Framework

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 ...

Extracting Mellin moments of double parton distributions from lattice data

Journal of High Energy Physics
Reconstructing 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.
