Distributional celestial amplitudes

Journal of High Energy Physics
Scattering amplitudes are tempered distributions, which are defined through their action on functions in the Schwartz space S ℝ $$ \mathcal{S}\left(\mathbb{R}\right) $$ by duality.

Exploring Role and Experience Factors on a Virtual, ECHO‐Based School Mental Health Professional Development Program: An Implementation Science Perspective

Psychology in the Schools, Volume 63, Issue 8, Page 1321-1333, August 2026.
ABSTRACT In‐service training for school staff, generally referred to as professional development (PD), may bolster a school's capacity for implementing school mental health (SMH) services. However, not all PD results in knowledge or behavior change. In one model of PD, Project Extension for Community Healthcare Outcomes (ECHO), participants collaborate

Modelling the national breeding distribution and population size of an elusive forest bird, the Eurasian Woodcock (Scolopax rusticola)

Ibis, Volume 168, Issue 3, Page 1034-1054, July 2026.
Understanding the distribution of species is central to conservation biology. Species distribution modelling (SDM) is a standard method used for this purpose, especially for elusive species for which limited occurrence data exist. The Eurasian Woodcock Scolopax rusticola (hereafter Woodcock) is an elusive, woodland‐dwelling wader that is declining in ...

Estimates and properties of certain q-Mellin transform on generalized q-calculus theory

Advances in Difference Equations, 2021
This paper deals with the generalized q-theory of the q-Mellin transform and its certain properties in a set of q-generalized functions. Some related q-equivalence relations, q-quotients of sequences, q-convergence definitions, and q-delta sequences are ...

Will the Mediterranean Sea Be a Cul‐de‐Sac for Marine Gastropods Under Climate Change?

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Marine benthic gastropods remain understudied despite extensive historical records, limiting our understanding of their vulnerability to climate change. Using multi‐temporal species distribution models, we show that intermediate future climate conditions may trigger major habitat contractions for four key cowrie and frog‐shell species in the NE ...

The theory of island biogeography and the stability of oceanic reef fish communities

Journal of Fish Biology, Volume 108, Issue 6, Page 2041-2052, June 2026.
Abstract Reef fish assemblages on oceanic islands offer valuable insights into ecological and evolutionary processes, yet their temporal dynamics remain poorly understood. This study evaluates the theory of island biogeography (TIB) with long‐term ecological monitoring to assess how island area, isolation from nearest reef and distance from mainland ...

Tree-level gluon amplitudes on the celestial sphere

Physics Letters B, 2018
Pasterski, Shao and Strominger have recently proposed that massless scattering amplitudes can be mapped to correlators on the celestial sphere at infinity via a Mellin transform. We apply this prescription to arbitrary n-point tree-level gluon amplitudes.

Solving the n $n$‐Player Tullock Contest

Journal of Public Economic Theory, Volume 28, Issue 2, April 2026.
ABSTRACT The n $n$‐player Tullock contest with complete information is known to admit explicit solutions in special cases, such as (i) homogeneous valuations, (ii) constant returns, and (iii) two contestants. But can the model be solved more generally?

Jumping hedges on the strength of the Mellin transform

Results in Applied Mathematics, 2022
With more looming uncertainties in our present financial climate and environment, models with jump–diffusion more than ever are necessary. They are suited to reproduce the large and sudden fluctuations in the level of the underlying variable, and mimic ...
