Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.Abstract Magnetic reconnection is a highly dynamic process that excites a wide variety of kinetic waves and instabilities. Transverse current sheet instabilities such as the lower‐hybrid drift and secondary drift‐kink instabilities in particular have been shown by kinetic simulations to modify the reconnection and introduce significant turbulence and ...

Padé approximant related to inequalities for Gauss lemniscate functions
Journal of Inequalities and Applications, 2016 Based on the Padé approximation method, we present new inequalities for Gauss lemniscate functions. We also solve a conjecture on inequalities for Gauss lemniscate functions proposed by Sun and Chen.

Journal of Computational Chemistry, Volume 47, Issue 17, 30 June 2026.A post‐SCF energy‐corrected local‐hybrid scheme, EC(LH)@(m)GGA, is introduced, in which hyper‐meta‐GGA ingredients obtained from inexpensive meta‐GGA or GGA orbitals are used as input for a single local‐hybrid energy evaluation. Using LH25nP as a prototype, this strategy retains the characteristic accuracy and strong‐correlation improvement of the ...

Scaled and Squared Subdiagonal Padé Approximation for the Matrix Exponential
SIAM Journal on Matrix Analysis and Applications, 2016 The scaling and squaring method is the most widely used algorithm for computing the exponential of a square matrix $A$. We introduce an efficient variant that uses a much smaller squaring factor when $\|A\| \gg 1$ and a subdiagonal Pade approximant of ...

FINANCIAL PLANNING REVIEW, Volume 9, Issue 2, June 2026.ABSTRACT This study explores how the components of the Theory of Planned Behavior (attitude, subjective norms, and perceived behavioral control) affect retirement financial planning among Millennials in the Klang Valley, Malaysia, focusing on the moderating role of financial self‐efficacy. A quantitative approach was adopted, with survey data collected

A Novel Analytical Interpolation Approach for Determining the Locus of a Zoom Lens Optical System
PhotonicsIn an optical system with multiple lens groups and increased zoom magnification levels, achieving a smooth zoom locus is increasingly difficult. Traditional methods for calculating zoom loci often involve complex and time-consuming formulas. Consequently,

Padé Approximant and Minimax Rational Approximation in Standard Cosmology
Galaxies, 2016 The luminosity distance in the standard cosmology as given by ΛCDM and, consequently, the distance modulus for supernovae can be defined by the Padé approximant.

Refinements of certain hyperbolic inequalities via the Padé approximation method
, 2016 The aim of this paper is to deal with the refinements of certain inequalities for hyperbolic functions using Padé approximation method. We provide a useful way of improving the inequalities for trigonometric functions and hyperbolic functions.

Iterative Krylov Subspace Methods for Linear Port‐Hamiltonian Systems
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT In this work, we present a structure‐preserving Krylov subspace iteration scheme for solving the equation systems that arise from the Gauss integration of linear energy‐conserving and dissipative differential systems (e.g., Poisson systems, gradient systems, and port‐Hamiltonian systems).

High Voltage, Volume 11, Issue 3, Page 725-737, June 2026.ABSTRACT The stability analysis of Line Commutated Converter High Voltage Direct Current (LCC‐HVDC) is of considerable engineering importance. Establishing its analytical mathematical model helps to analyse stability and the factors that affect stability of the system.
