Generalized parton correlation functions for a spin-1/2 hadron

, 2009
The fully unintegrated, off-diagonal quark-quark correlator for a spin-1/2 hadron is parameterized in terms of so-called generalized parton correlation functions.

Performance, cardioventilatory and perceptual responses to perceived opponent ability during head‐to‐head cycling competition

Experimental Physiology, EarlyView.
Abstract We aimed to investigate whether cycling competition influences performance and pacing compared to an individual time trial. The second aim was to determine whether performance is further influenced by deceptive or accurate augmented feedback, delivered as an opponent riding at 2% higher power outputs than a previous competitive time trial ...

The Kaon Off-Shell Generalized Parton Distributions and Transverse Momentum Dependent Parton Distributions

Particles
We investigate the off-shell generalized parton distributions (GPDs) and transverse momentum dependent parton distributions (TMDs) of kaons within the framework of the Nambu–Jona-Lasinio model, employing proper time regularization.

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

Two-loop splitting in double parton distributions: the colour non-singlet case

Journal of High Energy Physics, 2021
At small inter-parton distances, double parton distributions receive their dominant contribution from the splitting of a single parton. We compute this mechanism at next-to-leading order in perturbation theory for all colour configurations of the ...

Viewing the Proton Through "Color"-Filters

, 2003
While the form factors and parton distributions provide separately the shape of the proton in coordinate and momentum spaces, a more powerful imaging of the proton structure can be obtained through phase-space distributions.

Pion Parton Distributions in a non local Lagrangian [PDF]

, 2006
We use phenomenological nonlocal Lagrangians, which lead to non trivial forms for the quark propagator, to describe the pion. We define a procedure, based on the Dyson-Schwinger equations, for the calculation of the pion parton distributions at low Q^2 ...

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 ...
