Superstability of micrometre jets surrounded by a polymeric shell. [PDF]
J Appl CrystallogrSuperstable micrometre compound jets have been produced for serial femtosecond X‐ray crystallography.We have produced superstable compound liquid microjets with a 3D‐printed coaxial flow‐focusing injector. The aqueous jet core is surrounded by a shell, a few hundred nanometres in thickness, of a low‐concentration aqueous solution of a low‐molecular ...

Nonlinear evolution of harmonically forced perturbations on a wingtip vortex [PDF]
, 2016 Wingtip vortices are created by flying airplanes due to lift generation. The vortex interaction with the trailing aircraft has sparked researchers’ interest to develop an efficient technique to destroy these vortices.

Materials Genome Engineering Advances, EarlyView.Four constitutive models are evaluated for FeCoNiCr and Al0.6FeCoNiCr HEAs under wide temperature and strain‐rate conditions. The predictive capabilities and limitations of each model are then critically assessed, with particular emphasis on strain rate sensitivity, temperature dependence, and physically unrealistic responses at extreme loading ...

Deep Reinforcement Learning‐Based Control for Real‐Time Hybrid Simulation of Civil Structures
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Real‐time Hybrid Simulation (RTHS) is a cyber‐physical technique that studies the dynamic behavior of a system by combining physical and numerical components that are coupled through a boundary condition enforcer. In structural engineering, the numerical components are subjected to environmental loads that become dynamic displacements of the ...
