Inhomogeneous broadening in the time domain
Nanophotonics, Volume 14, Issue 23, Page 4177-4196, 02 November 2025.Abstract Forty‐five years after the initial attempts – first by Efimov–Khitrov in 1979, then by Brendel–Bormann in 1992 – we present a comprehensive, causal, and physically consistent framework for modeling the dielectric function with inhomogeneous (non‐Lorentzian) broadening, where scattering becomes frequency‐ or time‐dependent.

Identifying redundant singularity in Padé approximant
The Padé approximant performs the pole analysis in statistical mechanics and particle physics. The Padé approximant can recover the singularity information lost in the polynomial approximation given by perturbation methods but also introduces redundant ...

International Journal of Differential Equations, 2015 We combine the Adomian decomposition method (ADM) and Adomian’s asymptotic decomposition method (AADM) for solving Riccati equations. We investigate the approximate global solution by matching the near-field approximation derived from the Adomian ...

New asymptotic expansions and Padé approximants related to the triple gamma function
Journal of Inequalities and Applications, 2022 In this work, our main focus is to establish asymptotic expansions for the triple gamma function in terms of the triple Bernoulli polynomials. As application, an asymptotic expansion for hyperfactorial function is also obtained.

On the Density–Density Correlations of the Non‐Interacting Finite Temperature Electron Gas
Contributions to Plasma Physics, Volume 65, Issue 8-9, October 2025.ABSTRACT The density–density correlations of the non‐interacting finite temperature electron gas are discussed in detail. Starting from the ideal linear density response function and utilizing general relations from linear response theory, known and novel expressions are derived for the pair correlation function, static structure factor, dynamic ...

Elastic Wave Scattering Calculations and the Matrix Variational Padé Approximant Method [PDF]
, 1981 The matrix variational Padé approximant and its generalization to elastic wave scattering are discussed. Predictions of the method for the scattering of a longitudinal plane wave are compared with the exact scattering from spherical voids and inclusions.

A Novel Approach to Design Flood Hydrograph Plotting in Water Management
Applied SciencesThis study proposes a unified analytical framework for plotting design flood hydrographs (DFH) based on four characteristic parameters: total duration (Tt), time to peak (Tp), flood volume (W), and peak discharge (Qp) associated with specific exceedance ...

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

Quarterly 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 ...

Multivariate Partial Newton-Padé and Newton-Padé Type Approximants
, 1993 The notion of partial Padé approximant is generalized to that of general order multivariate partial Newton-Padé approximant. Previously introduced multivariate Padé-type approximants are recaptured as special cases so that it is a true and unifying ...
