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.

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

Cytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Parton distributions [PDF]

, 2004
Parton distributions, α(χ,μ(^₂) are essential ingredients for almost all theoretical calculations at hadron colliders. They give the number densities of the colliding par- tons (quarks and gluons) inside their parent hadrons at a given momentum fraction ...

Parton distribution functions from Ioffe time pseudo-distributions

Journal of High Energy Physics, 2019
In this paper, we present a detailed study of the unpolarized nucleon parton distribution function (PDF) employing the approach of parton pseudo-distribution func- tions. We perform a systematic analysis using three lattice ensembles at two volumes, with

QED parton distribution functions in the MSHT20 fit

European Physical Journal C: Particles and Fields, 2022
We present the MSHT20qed set of parton distribution functions (PDFs). These are obtained from the MSHT20 global analysis via a refit including QED corrections to the DGLAP evolution at $${{{\mathcal {O}}}}(\alpha ),{{{\mathcal {O}}}}(\alpha \alpha _S ...

Supervision as a Dispersed Practice: Exploring the Creation of Supervisory Spaces in Day‐to‐Day Social Work Practice

Child &Family Social Work, EarlyView.
ABSTRACT Supervision is integral to social work practice; however, how it operates in day‐to‐day practice remains poorly understood. Existing research mainly comprises quantitative and qualitative accounts of social workers' and supervisors' experiences of supervision.

Does nuclear medium affect the transverse momentum-dependent parton distributions of valence quark of pions?

Physics Letters B
We calculate the valence quark transverse momentum-dependent parton distributions (TMDs) of the lightest pseudoscalar meson, pions, in isospin asymmetric nuclear matter at zero temperature by employing a light-cone quark model.

CTEQ-TEA parton distribution functions with intrinsic charm

EPJ Web of Conferences, 2018
We present a study in which the possibility of a (sizable) nonperturbative contribution to the charm parton distribution function (PDF) in a nucleon is investigated together with theoretical issues arising in its interpretation.

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 development of ‘assembly line principles’ in Swedish child welfare: Long‐serving social workers' experiences of phase specialisation

International Journal of Social Welfare, Volume 35, Issue 4, October 2026.
Abstract The child welfare system has increasingly adopted phase specialisation, in Sweden and internationally, dividing work into distinct stages. This study examines these changes through the retrospective perspectives of 15 long‐serving child welfare professionals, highlighting three key organisational shifts: the separation of statutory and ...
