A consistent coupling of two‐moment microphysics and bulk ice optical properties, and its impact on radiation in a regional weather model

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 151, Issue 772, October 2025 Part A.
This study presents a novel, consistent coupling of two‐moment microphysics (i.e., ice mass mixing ratio and number) with bulk ice optical properties, providing improved accuracy in radiative transfer simulations. The parametrisations, based on the mass‐equivalent spherical radius, avoid uncertainties associated with the effective radius by directly ...

Significance of thermal stress in a convective-radiative annular fin with magnetic field and heat generation: application of DTM and MRPSM

open access: yesPropulsion and Power Research, 2022
The present paper explains the temperature attribute of a convective-radiative rectangular profiled annular fin with the impact of magnetic field. The effect of thermal radiation, convection, and magnetic field on thermal stress distribution is also ...

Modeling Dynamic Electrochemical Impedance Spectroscopy Using a Linearization Technique

open access: yesChemElectroChem, Volume 12, Issue 18, September 15, 2025.
This article investigates the modeling of dynamic electrochemical impedance spectroscopy. Using a linearization technique, three mathematical models are defined – dynamic, stationary, and filtered. The results show a closeness of the dynamic model to the experimental practice and significant effects of nonstationarity in the low‐frequency region.

Padé-approximant corrections to general variational expressions of scattering theory: Application to 5σ photoionization of carbon monoxide [PDF]

open access: yes, 1983
We discuss a method for systematically correcting results obtained using variational expressions in scattering theory. The approach taken is to compute a sequence of Padé approximants of the form [N/N] for the error in an initial variational estimate ...

Artificial Neural Networks Fitting of Potential Energy Curves and Surfaces: The 1/R Conundrum

open access: yesJournal of Computational Chemistry, Volume 46, Issue 24, September 15, 2025.
ANN fit of electronic energies and adding internuclear repulsion gives accurate potential energy surfaces. ABSTRACT Within the Born‐Oppenheimer approximation, the potential energy of a molecular system is written as a sum of electronic energy and nuclear‐nuclear repulsion energy terms.

A New Special Function and Its Application in Probability

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2018
In this note we present a new special function that behaves like the error function and we provide an approximated accurate closed form for its CDF in terms of both Chèbyshev polynomials of the first kind and the error function.

N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills thermodynamics to order λ 2

open access: yesJournal of High Energy Physics, 2021
We calculate the resummed perturbative free energy of N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills in four spacetime dimensions (SYM4,4) through second order in the ’t Hooft coupling λ at finite temperature and zero chemical potential.
