These random molecules were fed a collection of three-base-long RNAs, each linked to a chemical tag. The idea was that if a molecule is capable of ligating one of these short RNA fragments to itself, ...

From vaccines and diagnostics to emerging gene-based therapies, RNA molecules are now central to modern medicine. But as their use continues to grow, so does a fundamental challenge: producing RNA ...

Abstract: This paper investigates the optimal guidance for hypersonic vehicles to achieve the maximum downrange. To handle the complex constraints during the reentry flight, we design a novel barrier ...
