The Fermi-Pasta-Ulam problem: 50 years of progress

, 2005
A brief review of the Fermi-Pasta-Ulam (FPU) paradox is given, together with its suggested resolutions and its relation to other physical problems. We focus on the ideas and concepts that have become the core of modern nonlinear mechanics, in their ...

Resolving Interpretation Challenges in Machine Learning Feature Selection With an Iterative Approach in Biomedical Pain Data

European Journal of Pain, Volume 30, Issue 2, February 2026.
ABSTRACT Background Machine learning (ML) is increasingly used to analyse pain‐related data, emphasising how well variables classify individuals, that is, training an algorithm to assign people to predefined groups such as high versus low pain sensitivity, rather than focusing on p‐values.

Ulam stability for second-order linear differential equations with three variable coefficients

Results in Applied Mathematics, 2022
This study deals with Ulam stability of second-order linear differential equations of the form e(x)y′′+f(x)y′+g(x)y=0. The method established by Cădariu et al. (2020) is extended.

Approximate Homomorphisms of Ternary Semigroups

, 2005
A mapping $f:(G_1,[ ]_1)\to (G_2,[ ]_2)$ between ternary semigroups will be called a ternary homomorphism if $f([xyz]_1)=[f(x)f(y)f(z)]_2$. In this paper, we prove the generalized Hyers--Ulam--Rassias stability of mappings of commutative semigroups into ...

Designing with Li2S in Lithium–Sulfur Batteries: From Fundamental Chemistry to Practical Architectures

Small, Volume 22, Issue 9, 12 February 2026.
This perspective highlights the design evolution of Li2S‐based lithium‐batteries, illustrating sulfur redox chemistry and Li2S activation. Emphasis is placed on catalytic interfaces, hierarchical carbon frameworks, and electrolyte‐solvation co‐design, enabling lithium‐free, anode‐free, and solid‐state Li‐S architectures for high‐energy, manufacturable ...

Cnoidal Waves on Fermi-Pasta-Ulam Lattices [PDF]

, 2012
We study a chain of infinitely many particles coupled by nonlinear springs, obeying the equations of motion [\ddot{q}_n = V'(q_{n+1}-q_n) - V'(q_n-q_{n-1})] with generic nearest-neighbour potential $V$.

Generalized Hyers–Ulam Stability of Laplace Equation With Neumann Boundary Condition in the Upper Half‐Space

Mathematical Methods in the Applied Sciences, Volume 49, Issue 2, Page 521-530, 30 January 2026.
ABSTRACT This paper investigates the generalized Hyers–Ulam stability of the Laplace equation subject to Neumann boundary conditions in the upper half‐space. Traditionally, Hyers–Ulam stability problems for differential equations are analyzed by examining the system's error, particularly in relation to a forcing term.
