Agricultural Emissions of Reactive Nitrogen Gases From Constrained Simulations Using the Community Land Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Reactive nitrogen (Nr) gases (NH3, N2O, and NO) emitted from agricultural fields constitute a substantial portion of the Nr flux from land to the atmosphere. Here, we coupled the Flows of Agricultural Nitrogen (FANv3) with a modified version of the Community Land Model (CLM5.1) to produce a model (CLM‐FANv3) that simulates the emissions of NH3,

Parton distribution functions from scalar light-front parton gas model [PDF]

We model the structure of hadrons by a confined parton gas with light-front kinematics. These partons are treated as classical spin-zero particles confined inside the hadron with inter-parton collisions as their only interaction.

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.

Parton Distribution Function Uncertainties [PDF]

, 2001
We present parton distribution functions which include a quantitative estimate of its uncertainties. The parton distribution functions are optimized with respect to deep inelastic proton data, expressing the uncertainties as a density measure over the ...

Transversity parton distribution functions from lattice QCD

, 2018
We present the first direct calculation of the renormalized transversity parton distribution function within the nucleon from lattice QCD. The calculation is performed using simulations with the light quark mass fixed to its physical value and at one ...

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.
