The Magnetic Field from Cylindrical Arc Coils and Magnets: A Compendium with New Analytic Solutions for Radial Magnetization and Azimuthal Current

Advanced Physics Research, Volume 3, Issue 7, July 2024.
This study provides analytic solutions for the magnetic field of coils and magnets that have a non‐axisymmetric cylindrical geometry with a rectangular cross‐section. The equations can be readily applied to find the magnetostatic field in linear or non‐linear systems that contain a large set of elements.

A seven‐step guide to spatial, agent‐based modelling of tumour evolution

Evolutionary Applications, Volume 17, Issue 5, May 2024.
Abstract Spatial agent‐based models are frequently used to investigate the evolution of solid tumours subject to localized cell–cell interactions and microenvironmental heterogeneity. As spatial genomic, transcriptomic and proteomic technologies gain traction, spatial computational models are predicted to become ever more necessary for making sense of ...

Celestial conformal blocks of massless scalars and analytic continuation of the Appell function F 1

Journal of High Energy Physics
In celestial conformal field theory (CCFT), the 4d massless scalars are represented by 2d conformal operators with conformal dimensions h = h ¯ $$ \overline{h} $$ = (1 + iλ)/2.

MONOTONICITY AND CONVEXITY PROPERTIES OF THE NIELSEN’S β-FUNCTION

Проблемы анализа, 2017
The Nielsen’s β-function provides a powerful tool for evaluating and estimating certain integrals, series and mathematical constants. It is related to other special functions such as the digamma function, the Euler’s beta function and the Gauss ...

Riesz energy, L2$L^2$ discrepancy, and optimal transport of determinantal point processes on the sphere and the flat torus

Mathematika, Volume 70, Issue 2, April 2024.
Abstract Determinantal point processes exhibit an inherent repulsive behavior, thus providing examples of very evenly distributed point sets on manifolds. In this paper, we study the so‐called harmonic ensemble, defined in terms of Laplace eigenfunctions on the sphere Sd$\mathbb {S}^d$ and the flat torus Td$\mathbb {T}^d$, and the so‐called spherical ...

Delbrück Scattering above the Pair Production Threshold: Going beyond the Born Approximation

Annalen der Physik, Volume 536, Issue 3, March 2024.
This article presents an accurate approach for the calculation of Delbrück scattering amplitudes above the electron–positron pair production threshold that accounts for the Coulomb interaction with nucleus to all orders in αZ$\alpha Z$. Explicit calculations for the scattering of 2.754 MeV photons by zinc, cerium, lead, and plutonium nuclei are ...

A streamlined user grouping in downlink NOMA systems

Electronics Letters, Volume 60, Issue 2, January 2024.
We have come up with a streamlined user grouping scheme for a four‐user cluster in downlink NOMA systems. This proposed scheme is designed based on PAM modulation, the Gray mapping rule, and the joint maximum‐likelihood detector. The streamlined user grouping gives outstanding BER performance in comparison to the conventional NOMA without user grouping
