ChiliPDF: Chebyshev interpolation for parton distributions

European Physical Journal C: Particles and Fields, 2022
Parton distribution functions (PDFs) are an essential ingredient for theoretical predictions at colliders. Since their exact form is unknown, their handling and delivery for practical applications relies on approximate numerical methods.

Hyperspectral Fingerprinting of Dune Sediments Across the Arabian Peninsula: Insights Into Sediment Provenance and Transport Pathways From NASA's EMIT Data

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 ...

New information on parton distributions [PDF]

Physical Review D, 1993
New data on structure functions from deep-inelastic scattering provide new information on parton distributions, particularly in the $0.01lxl0.1$ interval. This has important implications for predictions for the DESY $\mathrm{ep}$ collider HERA and for present and future high-energy hadron colliders.

The Importance of Scale in the Future of Mangrove Blue Carbon Under Sea‐Level Rise

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract As efficient carbon sinks, mangrove forests are crucial for climate change mitigation. However, their vulnerability to sea‐level rise (SLR) and human activities influencing sediment supply introduces significant uncertainty regarding their future carbon storage capacity.

Impacts of Precipitation Variability on Carbon Flux Dynamics of Global Semi‐Arid Savannas

Global Change Biology, Volume 32, Issue 6, June 2026.
Semi‐arid ecosystems contribute most to the variability of the land carbon sink. They are water‐limited and therefore increased precipitation variability due to climate change has strong effects on their carbon cycle. We investigate the effects of precipitation amount, frequency, intensity and dry spell length on carbon fluxes of global semi‐arid ...

Subtle differences in spring soil moisture can substantially influence annual productivity in a semiarid grassland

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract In the C4‐dominated semiarid grasslands of the western Great Plains (Colorado, USA), spring soil moisture (soil volumetric water content, SoilVWC) is thought to be a critical determinant of aboveground net primary production (ANPP) and overall carbon cycling. However, because evidence for this is based on observational studies, we attempted to

Parton Distributions

, 2009
We provide an assessment of the state of the art in various issues related to experimental measurements, phenomenological methods and theoretical results relevant for the determination of parton distribution functions (PDFs) and their uncertainties, with the specific aim of providing benchmarks of different existing approaches and results in view of ...

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 ...

ProCarbon‐Soil: A dynamic model for improved model‐data compatibility in carbon farming

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Carbon farming is a nature‐based solution to capture atmospheric CO2 and store it as soil organic carbon (SOC). Carbon farming trading schemes (CFTS) incentivize farmers to adopt these practices. Integral to CFTS is forecasting SOC changes, typically achieved using traditional multicompartmental soil carbon models (mSCM), and monitoring total ...
