Spring and Power in Hovering Ornithopters
Advanced Intelligent Systems, EarlyView.Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...

Nanomechanical Systems for Reservoir Computing Applications
Advanced Intelligent Systems, EarlyView.Nanoelectromechanical systems (NEMS) are known for their strong nonlinear response, which can be conducive for reservoir computing. In this work, the authors build an NEMS‐based reservoir and investigate the classification accuracy as a function of drive levels and operation points.

Harmonic Solution of Higher-Dimensional Second Order Kuramoto Oscillator Network
IEEE AccessObtaining the solution of Kuramoto oscillator model is an effective way to understand the mechanism behind the dynamical behaviors it represents. However, it is not an easy work to get, even the approximation solution for the second order Kuramoto ...

Tuning Antiaromaticity Through Meso‐Substituent Orientation in Core‐Modified Isophlorins
Asian Journal of Organic Chemistry, EarlyView.The antiaromaticity of dithiadioxaisophlorins is controlled by the steric bulkiness of meso‐substituents through their tilt angle relative to the macrocycle. Bulkier substituents maintain larger angles, preserving stronger antiaromaticity, while smaller groups facilitate π‐conjugation with the macrocycle, diminishing antiaromaticity.

Discretized representations of harmonic variables by bilateral Jacobi operators
Discrete Dynamics in Nature and Society, 2000 Starting from a discrete Heisenberg algebra we solve several representation problems for a discretized quantum oscillator in a weighted sequence space. The Schrödinger operator for a discrete harmonic oscillator is derived. The representation problem for
