Uniqueness theorems for Sturm-Liouville operators with interior twin-dense nodal set
Electronic Journal of Differential Equations, 2017 We study Inverse problems for the Sturm-Liouville operator with Robin boundary conditions. We establish two uniqueness theorems from the twin-dense nodal subset $W_{S}([\frac{1-\varepsilon}{2},\frac{1}{2 ...

A Novel Mixed‐Hybrid, Higher‐Order Accurate Formulation for Kirchhoff–Love Shells
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT This paper presents a novel mixed‐hybrid finite element formulation for Kirchhoff–Love shells, designed to enable the use of standard C0$C^0$‐continuous higher‐order Lagrange elements. This is possible by introducing the components of the moment tensor as a primary unknown alongside the displacement vector, circumventing the need for C1$C^1 ...

Denoising Diffusion Model With Pixel‐Adaptive Convolutions for Sheet Metal Forming Analysis
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT Traditional tool development processes in mechanical forming, especially for pressing tools, are often limited by time‐consuming trial‐and‐error cycles, which rely heavily on expert knowledge. These cycles can create bottlenecks and increase costs.

Quantum Information Measures of a Dirichlet Waveguide with Neumann Window(s)
Advanced Quantum Technologies, Volume 9, Issue 6, June 2026.ABSTRACT Engineering boundary conditions in low‐dimensional structures provides a simple yet powerful way of shaping how quantum information is stored and transported. We investigate a flat 2D Dirichlet waveguide containing one or two finite Neumann windows and compute the bound states in both position and momentum space as functions of the window ...

Modeling Length Adjustment in Alluvial Anabranching Units
Water Resources Research, Volume 62, Issue 6, June 2026.Abstract Anabranching units form when the stream flow divides into two channels that reconnect downstream. Recent observations indicate that these patterns tend to develop fairly regular planforms, characterized by an average length that scales with reach‐averaged channel geometry and by weak asymmetry between the anabranches.

A Stable and Accurate X‐FFT Solver for Linear Elastic Homogenization Problems in 3D
International Journal for Numerical Methods in Engineering, Volume 127, Issue 10, 30 May 2026.ABSTRACT Although FFT‐based methods are renowned for their numerical efficiency and stability, traditional discretizations fail to capture material interfaces that are not aligned with the grid, resulting in suboptimal accuracy. To address this issue, the work at hand introduces a novel FFT‐based solver that achieves interface‐conforming accuracy for ...

The inverse nodal problem for a differential operator with an eigenvalue in the boundary condition
Applied Mathematics Letters, 2008 The paper considers the Sturm-Liouville problem given by the second-order ODE \[ y''(x)+ [\lambda^2+ \mu- q(x)]y(x)= 0,\qquad x\in (0,\pi)\tag{1} \] subject to the boundary conditions \[ y(0)= 0,\quad ay'(\pi)+\lambda y(\pi)= 0,\tag{2} \] where \(q\in L^1([0,\pi])\), \(\mu\in \mathbb{R}\), \(a\in\mathbb{R}^*\), \(\lambda\) is eigenvalue.
