Accurate and Efficient Data‐Driven Partitioned Scheme for Coupled Heterogeneous Numerical Models

open access: yesNumerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.
ABSTRACT Heterogeneous numerical models (HNMs) combine conventional discretization modules such as finite elements with nonconventional data‐driven and reduced‐order modules. HNMs can improve computational efficiency and enable simulations of multi‐physics systems in which one or more constituent components lack first‐principles descriptions and must ...

Model Predictive Control of Gas Networks Based on Port‐Hamiltonian Formulations

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 3, September 2026.
ABSTRACT To efficiently compute optimal compressor actions in gas networks, we investigate port‐Hamiltonian models consisting of linear and a nonlinear model assumptions. The control actions are derived via adjoint‐based gradients that incorporate the constraints of the underlying optimization problem. We then present results from the implementation of

Key Technical Fields and Future Outlooks of Space Manipulators: A Survey

open access: yesSmartBot, Volume 2, Issue 3, September 2026.
This paper systematically reviews the technological development of space manipulators, emphasizing the unique challenges posed by space environments. It examines four areas: structural design, modeling, planning, and control, while introducing typical ground test platforms.

Monetary Policy When Preferences Are Quasi‐Hyperbolic

open access: yesJournal of Money, Credit and Banking, Volume 58, Issue 6, Page 1729-1757, September 2026.
Abstract We study discretionary monetary policy in an economy where economic agents have quasi‐hyperbolic discounting. We demonstrate that a benevolent central bank is able to keep inflation under control for a wide range of discount factors. If the central bank, however, does not adopt the household's time preferences and tries to discourage early ...

On para-Euler-Lagrange and para-Hamiltonian equations

open access: yes, 2005
In the framework of para-Kählerian manifolds, we introduce paracomplex analogue of Euler-Lagrange and Hamiltonian equations. Furthermore, the geometric results on the related mechanic systems have been given. © 2005 Elsevier B.V.

Monetary and Macroprudential Policies under Dollar‐Denominated Foreign Debt

open access: yesJournal of Money, Credit and Banking, Volume 58, Issue 6, Page 1693-1728, September 2026.
Abstract This paper studies monetary and macroprudential policies in a small open economy that borrows from abroad in foreign currency. The model features a novel mechanism in which exchange rate depreciation triggered by a borrowing constraint is amplified through balance of payments adjustments, increasing the real burden of foreign debt and causing ...

Equilibrium Shapes with Stress Localisation for Inextensible Elastic Mobius and Other Strips [PDF]

open access: yes, 2015
We formulate the problem of finding equilibrium shapes of a thin inextensible elastic strip, developing further our previous work on the Möbius strip. By using the isometric nature of the deformation we reduce the variational problem to a second-order ...

Factorizations in Hecke algebras I: Long‐cycle factorizations and Jucys–Murphy elements

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract Given a permutation, there is a well‐developed literature studying the number of ways one can factor it into a product of other permutations subject to certain conditions. We initiate the analogous theory for the type‐A$A$ Iwahori–Hecke algebra by generalizing the notion of factorization in terms of the Jucys–Murphy elements.

WILD SOLUTIONS TO SCALAR EULER-LAGRANGE EQUATIONS

open access: yes
. We study very weak solutions to scalar Euler-Lagrange equations associated with quadratic convex functionals. We investigate whether W1,1 solutions are necessarily W 1,2 Nash and Schauder applicable.
