Chaotic Response and Bifurcation Analysis of a Timoshenko Beam with Backlash Support Subjected to Moving Masses [PDF]

International Journal of Railway Research, 2014
A simply supported Timoshenko beam with an intermediate backlash is considered. The beam equations of motion are obtained based on the Timoshenko beam theory by including the dynamic effect of a moving mass travelling along the vibrating path.

Quasibounded solutions to the complex Monge–Ampère equation

Bulletin of the London Mathematical Society, Volume 58, Issue 4, April 2026.
Abstract We study the Dirichlet problem for the complex Monge–Ampère operator on B‐regular domains in Cn$\mathbb {C}^n$, allowing boundary data that is singular or unbounded. We extend the concept of pluri‐quasibounded functions on the domain to functions on the boundary, defined by the existence of plurisuperharmonic majorants that dominate their ...

Proprioceptive integration in motor control

The Journal of Physiology, Volume 604, Issue 8, Page 3431-3456, 15 April 2026.
Abstract figure legend A virtual reality (VR)‐based reaching task reveals how proprioceptive feedback affects the perceived and actual movement speed of active movements, as well as the perceived hand position. When an antagonist vibration was applied, subjects tended to overestimate their movement speed while also decreasing their actual movement ...

Mutual 3:1 subharmonic synchronization in a micromachined silicon disk resonator [PDF]

, 2017
We demonstrate synchronization between two intrinsically coupled oscillators that are created from two distinct vibration modes of a single micromachined disk resonator.

Charge Transport Across Single Molecules at the Metal–Superconductor Interface

Small, Volume 22, Issue 12, 25 February 2026.
The evolution of Andreev reflection in single‐molecule junctions is probed with the decreasing distance between a normal‐metal tip and a conventional superconductor. Andreev reflection becomes most effective when a molecular orbital straddles the Fermi level.

Threshold lowering for subharmonic generation in Cantor-like composite structures

, 1992
We show evidence of extremely low thresholds for subharmonic generation in one-dimensional artificial composites with hierarchical structure, as compared to the corresponding homogeneous and periodic structures.

Instabilities and subharmonic resonances of subsonic-heated round jets.

, 1990
When a jet is perturbed by a periodic excitation of suitable frequency, a large-scale coherent structure develops and grows in amplitude as it propagates downstream. The structure eventually rolls up into vortices at some downstream location.

Collective lattice excitations in the dynamic route for melting hydrodynamic two-dimensional crystals

Physical Review Research
Liquid surface stiffness generates stable Faraday wave (FW) patterns, known as hydrodynamic crystals, which form resonant FW lattices composed of discrete harmonics and subharmonics under monochromatic driving.
