Open AccessStrongly coupled magneto-exciton condensates in large-angle twisted double bilayer graphene
Excitons, pairs of electrons and holes, undergo a Bose-Einstein condensation at low temperatures. An important platform to study excitons is double-layer two-dimensional electron gases, with two parallel plane...

Diagnostic Measures for Functional Linear Model with Nonignorable Missing Responses
Assessing the influence of individual observations of the functional linear models is important and challenging, especially when the observations are subject to missingness. In this paper, we introduce three c...

Air–Water Interface Jetting Induced by Explosion Load
Explosion in liquid emits a shock wave and induces a radial flow with a bubble in center. When it occurs near a free surface, a jet may develop. The effect can be enhanced by restricting the flow only to the j...

Influence of Gaseous Contaminations on Performance and Operability of a Scramjet Inlet
The simulation of hypersonic flight condition on ground requires preheating of the working flow medium. The preheating process, however, may introduce a sort of side effect known as ‘vitiation’ or ‘contaminati...
