Richard Plotkin. Project: Role of interface mixing on coherent phonon mode-conversion in aperiodic superlattice Progress or exciting results: This project seeks to advance our understanding of the ...

Chemists identify a single molecule that naturally tiles in nonrepeating patterns, which could help build materials with novel electronic properties.

Abstract: In this article, the problem of data-driven control for Markovian jump systems (MJSs) under aperiodic sampled-data (ASD) control is studied. By constructing a loop-based Lyapunov functional ...

Intelligence is the the mental capacity for abstract reasoning, planning ability, logical thought, conceptual complexity and problem solving. High intelligence is thought to be associated with ...

A look back at the Office of Technology Assessment, the Congressional think tank that detected lies and tested tech.

Even more astonishing, every time the experiment was repeated, a different aperiodic pattern emerged. At first, Ernst and Voigt assumed there had been a mistake. But as they investigated further, they ...

Just as ice melts to water, graphs undergo phase transitions. Two mathematicians showed that they can pinpoint such transitions by examining only local structure. The Quanta Newsletter ...
