Programmable Multifunctional Bistable Structures for Energy Transfer and Dissipation [PDF]
Advanced Science, Volume 13, Issue 17, 23 March 2026.Utilizing the energy conversion characteristics of asymmetric bistable beams, this study develops a programmable multifunctional system composed of multiple bistable beams for energy transfer and dissipation. The high energy density enables the system to demonstrate potential in transient scenarios such as target delivery and shock absorption ...

Bernstein collocation technique for a class of Sturm-Liouville problems [PDF]
HeliyonSturm-Liouville problems have yielded the biggest achievement in the spectral theory of ordinary differential operators. Sturm-Liouville boundary value issues appear in many key applications in natural sciences. All the eigenvalues for the standard Sturm-

Spectral analysis of the matrix Sturm–Liouville operator
Boundary Value Problems, 2019 The self-adjoint matrix Sturm–Liouville operator on a finite interval with a boundary condition in general form is studied. We obtain asymptotic formulas for the eigenvalues and the weight matrices of the considered operator.

Coincidence Theory of a Nonlinear Periodic Sturm–Liouville System and Its Applications
Axioms, 2022 Based on the second derivative, this paper directly establishes the coincidence degree theory of a nonlinear periodic Sturm–Liouville (SL) system. As applications, we study the existence of periodic solutions to the S–L system with some special nonlinear

On the existence of generalised syzygies in the planar three-body problem
Comptes Rendus. Mathématique, 2023 We consider the Newtonian planar three-body problem. One defines a generalised syzygy as a configuration where the three bodies or their velocities become collinear.
