Control and ultrasonic actuation of a gas-liquid interface in a microfluidic chip

, 2009
This article describes the design and manufacturing of a microfluidic chip, allowing for the actuation of a gas-liquid interface and of the neighboring fluid. A first way to control the interface motion is to apply a pressure difference across it.

Information-flow interfaces

Formal Methods in System Design, 2022
Abstract Contract-based design is a promising methodology for taming the complexity of developing sophisticated systems. A formal contract distinguishes between assumptions, which are constraints that the designer of a component puts on the environments in which the component can be used safely, and guarantees, which are promises that the ...

Kinetics of exciton photoluminescence in type-II semiconductor superlattices [PDF]

, 2000
The exciton decay rate at a rough interface in type-II semiconductor superlattices is investigated. It is shown that the possibility of recombination of indirect excitons at a plane interface essentially affects kinetics of the exciton photoluminescence ...

Towards a critique of anti-German 'communism' [PDF]

, 2010
The spectre of anti-Germans has easily become the Feindbild for activists of the Anglophone Left; yet rarely does this translate into fundamental or informed criticism of the anti-German premise. This article, then, offers an introductory description and
