Drell-Yan lepton pair production at low invariant masses: transverse-momentum resummation and non-perturbative effects in QCD

Journal of High Energy Physics
We consider the transverse-momentum (q T ) distribution of Drell-Yan lepton pairs produced with invariant masses (M) from low values up to the Z-boson peak (4 ≤ M ≤ 116 GeV).

Transverse momentum in double parton scattering: factorisation, evolution and matching

Journal of High Energy Physics, 2018
We give a description of double parton scattering with measured transverse momenta in the final state, extending the formalism for factorisation and resummation developed by Collins, Soper and Sterman for the production of colourless particles.

Determination of nuclear parton distributions [PDF]

, 2001
Parametrization of nuclear parton distributions is investigated in the leading order of alpha_s. The parton distributions are provided at Q^2=1 GeV^2 with a number of parameters, which are determined by a chi^2 analysis of the data on nuclear structure ...

Updating carbon pool initialization within DSSAT‐CENTURY

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Allocation of C to conceptual C pools in the Decision Support System for Agrotechnology Transfer (DSSAT)‐CENTURY model determines the proportion of organic matter available for nutrient cycling. DSSAT‐CENTURY defaults to a pedotransfer function if relevant field history is unknown or a stable C value has not been provided.

Off-forward parton distributions and Shuvaev's transformations [PDF]

, 2000
We review Shuvaev's transformations, that relate off-forward parton distributions (OFPDs) to so-called effective forward parton distributions (EFPDs). The latter evolve like conventional forward partons.

Nano‐Enabled Toxicity of Pharmaceutical Excipients

WIREs Nanomedicine and Nanobiotechnology, Volume 18, Issue 3, May/June 2026.
Excipients regarded as safe in bulk form may become toxic once incorporated into nanocarriers. This review raises awareness of nano‐enabled toxicity and highlights analytical tools and safer alternative excipients to support risk‐mitigated nanomedicine development.

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.

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.

Tracking the Dynamics of human Colonisation and Adaptation in Central Vanuatu: Preliminary Results From Excavation and Survey at Pangpang, East Efate

Archaeology in Oceania, Volume 61, Issue 1, Page 221-236, April 2026.
ABSTRACT In October 2022 an extensive archaeological landscape was identified by staff of the Vanuatu Cultural Centre at Pangpang on the east coast of Efate Island in central Vanuatu. It included midden deposits on the banks of the Pangpang River near the sea at Forari Bay where Lapita and Early Erueti‐style pottery sherds were recovered.

Foliar pathogen epidemic slows decomposition of invasive plant litter

Ecology, Volume 107, Issue 4, April 2026.
Abstract Decomposition of plant litter, facilitated primarily by microbial decomposers, plays a critical role in biogeochemical cycling and ecosystem function. The rate of litter decomposition can determine its environmental impact, where accelerated decomposition alters the timing and rate of nutrient release and may promote nutrient leaching, whereas
