Parton distributions in the shockwave formalism

Journal of High Energy Physics
In this work, we calculate a broad class of parton distributions — including parton distribution functions (PDFs), transverse-momentum-dependent distributions (TMDs), generalized parton distributions (GPDs), generalized transverse-momentum-dependent ...

The Price Gap in Agriculture‐Based Greenhouse Gas Offset Markets

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Today, there is a global effort to reduce greenhouse gas net emissions (GHGNE). For economic well‐being, it is important to identify low‐cost means of net emission offsets. Agriculture and forestry have received considerable attention as a means of supplying emissions offsets, as they contribute nearly 20% of global emissions.

Parton distributions in the photon

Zeitschrift für Physik C Particles and Fields, 1994
We discuss in detail the photon structure function beyond the leading logarithm approximation. Of special concern is the factorization scheme and the hadronic input; we show how to naturally absorb large terms due to the MSbar factorization scheme in a modified hadronic component.

A model for the parton distributions in hadrons [PDF]

Physics Letters B, 1998
A simple model is presented for the parton distributions in hadrons. The parton momenta in the hadron rest frame are derived from a spherically symmetric, Gaussian, distribution having a width motivated by the Heisenberg uncertainty relation applied to the hadron size.

Intra‐Seasonal Crop Management and the Potential Benefit of Seasonal Precipitation Forecasts: Farm‐Level Embedded Risk Analysis in Ethiopia

Journal of Agricultural Economics, EarlyView.
ABSTRACT How large is the potential benefit for farmers from obtaining forecasts of total rainfall in the upcoming season? This critically depends on the local farm system and the crop management actions available to farmers to respond to the forecasts issued. Studies assessing the financial value of seasonal precipitation forecasts have so far focused

CTEQ5 parton distributions and ongoing studies. [PDF]

, 1999
The CTEQ5 parton distributions are described, with emphasis on the changes since CTEQ4. The most significant change is in the quark flavor dependence of the parton distributions. Ongoing studies of large-x parton distributions are discussed.

Kaon and pion parton distributions

European Physical Journal C: Particles and Fields, 2020
Beginning with results for the leading-twist two-particle distribution amplitudes of $$\pi $$ π - and K-mesons, each of which exhibits dilation driven by the mechanism responsible for the emergence of hadronic mass, we develop parameter-free predictions ...

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.

Generalized parton distributions and the dependence of parton distributions on the impact parameter [PDF]

AIP Conference Proceedings, 2001
Generalized parton distributions (GPDs) provide a link between form factors, parton distributions and other observables. I discuss the connection between GPDs and parton distributions as a function of the impact parameter. Since this connection involves GPDs in the limit of vanishing skewedness parameter $ξ$, i.e.

Unravelling the skin of the nurse shark: A morphological description of the placoid scales of Ginglymostoma cirratum

Journal of Fish Biology, EarlyView.
Abstract Ginglymostoma cirratum, commonly known as the nurse shark, is a nocturnally active benthic shark, often found in western and eastern Atlantic waters. Although this shark has been well explored in many biological aspects, few studies have thoroughly examined the morphology of its dermal denticles (or placoid scales).
