Optimised Operations and Modulation Scheme for Simplified Seven‐Level Hybrid‐Clamped Converters

IET Power Electronics
Seven‐level hybrid‐clamped (7L‐HC) converters are new and promising candidates for high‐power medium‐voltage applications. Their configurations can be simplified further by reducing one of the two flying capacitors per phase. However, such simplification

Bioinspired Shape‐Memory Hook Fasteners With Programmable Interlocking and Silent Release

Advanced Engineering Materials, EarlyView.
Bioinspired hook fasteners made from epoxy shape‐memory polymers are shown to switch between strong, secure attachment and gentle, silent release when heated. By combining programmable geometry and material response, these adaptive fasteners outperform commercial systems in strength and noise control, enabling new solutions for robotics, medical ...

Exponentially Adiabatic Switching in Quantum-Dot Cellular Automata

Journal of Low Power Electronics and Applications, 2018
We calculate the excess energy transferred into two-dot and three-dot quantum dot cellular automata systems during switching events. This is the energy that must eventually be dissipated as heat.

A variation on the tableau switching and a Pak-Vallejo's conjecture [PDF]

Discrete Mathematics & Theoretical Computer Science, 2008
Pak and Vallejo have defined fundamental symmetry map as any Young tableau bijection for the commutativity of the Littlewood-Richardson coefficients $c_{\mu,\nu}^{\lambda}=c_{\nu, \mu}^{\lambda}$.

Coherent Quantum Dynamics of a Superconducting Flux Qubit

, 2003
We have observed coherent time evolution between two quantum states of a superconducting flux qubit comprising three Josephson junctions in a loop. The superposition of the two states carrying opposite macroscopic persistent currents is manipulated by ...
