A Numerical Method Combining Cubic Interpolated Propagation and Shifted Grünwald–Letnikov for Fractional Advection–Dispersion Equations

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 8, Page 3546-3557, 10 June 2026.
ABSTRACT Recent advances in the numerical solution of fractional partial differential equations have yielded promising results. In particular, the Shifted Grünwald–Letnikov (SGL) approach allows for a generalization of the traditional finite difference method to the context of fractional differential equations.

Advancing Heliophysics and Space Weather Modeling Through Open Science

Space Weather, Volume 24, Issue 6, June 2026.
Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

Sensitivity analysis of spacecraft in micrometeoroids and orbital debris environment based on panel method

Defence Technology, 2023
To reduce the risk of mission failure caused by the MM/OD impact of the spacecraft, it is necessary to optimize the design of the spacecraft. Spacecraft survivability assessment is the key technology in the optimal design of spacecraft.

Disentangling Land‐Atmosphere Interactions via Multilevel Temporal Information Partitioning Networks

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Understanding Earth's hydrometeorological system requires characterizing the interactions at the land‐atmosphere interface. However, the multivariate nature of land‐atmosphere interactions across temporal scales and conditions remains insufficiently explored.

Euler‐Top Gaussian Modes: Structured Beams From Quadratic Angular Momentum Dynamics

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
A new family of structured Gaussian light beams are introduced: Euler‐top Gaussian modes. Their ray‐orbital paths on the Gaussian Poincaré sphere correspond to the polhodes of the Euler top in classical angular momentum theory. This geometric and algebraic construction reveals a nonseparable mode family extending the familiar Hermite‐, Laguerre‐ and ...

Higher-Order Hermite-Fejér Interpolation for Stieltjes Polynomials [PDF]

Journal of Applied Mathematics, 2013
Summary: Let \(w_\lambda(x):=(1-x^2)^{\lambda-1/2}\) and \(P_{\lambda,n}\) be the ultraspherical polynomials with respect to \(w_{\lambda}(x)\). Then, we denote the Stieltjes polynomials \(E_{\lambda,n+1}\) with respect to \(w_{\lambda}(x)\) satisfying \(\int_{-1}^1w_{\lambda}(x) P_{\lambda,n}(x)E_{\lambda,n+1}(x) x^m dx (=0, 0\leq m< n+1;\neq 0,m=n+1)\

Canyon effects structure fin whale feeding aggregations at Southern Ocean feeding grounds

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Large fin whale feeding aggregations at Southern Ocean feeding grounds are one of the most striking predator–prey phenomena in the post‐whaling era, representing a visible sign of recovering large whale populations. Yet, the mechanisms shaping their occurrence have not yet been studied. We investigate spatial patterns of fin whale distribution

On a method of Carasso and Laurent for constructing interpolating splines

, 1973
Carasso and Laurent studied a method for computing natural polynomial splines interpolating simple data. We discuss several similar methods which can be applied to numerical construction of more general interpolating splines, including Lg-splines ...

Impact of Uncertain Parameters on Navier–Stokes Equations With Heat Transfer via Polynomial Chaos Expansion

International Journal for Numerical Methods in Fluids, Volume 98, Issue 5, Page 557-577, May 2026.
This study investigates the impact of uncertain parameters on Navier–Stokes equations coupled with heat transfer using the Intrusive Polynomial Chaos Method (IPCM). Sensitivity equations are formulated for key input parameters, such as viscosity and thermal diffusivity, and solved numerically using the Finite Element‐Volume method.
