Binary Patterns in Binary Cube-Free Words: Avoidability and Growth [PDF]

, 2013
The avoidability of binary patterns by binary cube-free words is investigated and the exact bound between unavoidable and avoidable patterns is found. All avoidable patterns are shown to be D0L-avoidable.

Heterogeneous Wettability‐Based Construction of Two‐Phase Interfaces for Underwater Reversible Adhesion

Advanced Science, EarlyView.
The design employs heterogeneous wettability surfaces that construct stable oil‐water interfaces to achieve robust and rapid reversible adhesion. Linear enhancement of adhesion strength is realized through multi‐interface patterning. This adhesive enables rapid on‐demand detachment within five seconds via voltage‐induced electrolysis, offering a level ...

Integrating UUVs for naval applications

Maritime Technology and Research, 2021
Underwater surveillance technology was an advent of the Cold War. This technology saw numerous advancements only once the technology was declassified and pursued by academia. One such advancement in the maritime domain was the development of the Unmanned Underwater Vehicle (UUV) that has the ability to enhance war-fighting capabilities while de-risking
