On the deep‐water and shallow‐water limits of the intermediate long wave equation from a statistical viewpoint

Transactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.
Abstract We study convergence problems for the intermediate long wave (ILW) equation, with the depth parameter δ>0$\delta > 0$, in the deep‐water limit (δ→∞$\delta \rightarrow \infty$) and the shallow‐water limit (δ→0$\delta \rightarrow 0$) from a statistical point of view.

A Bi-Directional Coupling Calibration Model and Adaptive Calibration Algorithm for a Redundant Serial Robot with Highly Elastic Joints

Applied Sciences
This paper proposes a calibration method for redundant robot arms with highly elastic joints. The method uses the second-order Chebyshev polynomial to characterize the variation in the error with the poses of all joints.

Preconditioned iterative methods for Navier-Stokes control problems [PDF]

, 2013
PDE-constrained optimization problems are a class of problems which have attracted much recent attention in scientific computing and applied science. In this paper, we discuss preconditioned iterative methods for a class of Navier-Stokes control problems,

Comprehensive Mitigation of Peripheral and Central Stress Responses by Nx4: Insights From EEG and Heart Rate Variability in Post‐Stress Resting State

Human Psychopharmacology: Clinical and Experimental, Volume 40, Issue 6, November 2025.
ABSTRACT Objective Stress from daily psychosocial challenges is a significant health concern with limited pharmacological treatment options. Psychosocial stress triggers distinct responses in the autonomic and central nervous systems, measurable via heart rate variability (HRV) and electroencephalogram (EEG).

A Non‐Intrusive Efficient Two‐Step Model Reduction Method for Large‐Scale Thin‐Walled Acoustic Indirect BEM Systems

International Journal for Numerical Methods in Engineering, Volume 126, Issue 20, 30 October 2025.
ABSTRACT Performing frequency sweep analysis for acoustic performance prediction using the boundary element method (BEM) is associated with high computational costs as the associated system matrices are dense and frequency‐dependent. While model order reduction (MOR) techniques, such as Krylov subspace recycling, have been proposed for direct BEM ...

The iterative solution of the problem of orbit determination using Chebyshev series [PDF]

A method of orbit determination is investigated which employs Picard iteration and Chebyshev series. The method is applied to the problem of determining the orbit of an earth satellite from range and range-rate observations contaminated by noise.

Solving the Ghost-Gluon System of Yang-Mills Theory on GPUs

, 2012
We solve the ghost-gluon system of Yang-Mills theory using Graphics Processing Units (GPUs). Working in Landau gauge, we use the Dyson-Schwinger formalism for the mathematical description as this approach is well-suited to directly benefit from the ...

Accelerating the Structure Exploration of Diverse Bi–Pt Nanoclusters via Physics‐Informed Machine Learning Potential and Particle Swarm Optimization

ChemPhysChem, Volume 26, Issue 19, October 6, 2025.
AI‐guided swarms reveal Bi–Pt nanoparticle motifs. [Correction added on 28 October 2025, after the Issues published online: Older TOC text has been replaced with “AI‐guided swarms reveal Bi–Pt nanoparticle motifs”.] Bimetallic Bi–Pt nanoclusters exhibit diverse structural motifs, including core‐shell, Janus, and mixed alloy configurations, due to the ...
