40 Gbit=s Transmission and Cascaded All-optical Wavelength Conversion over 1 000 000 Km

Introduction: All-optical wavelength converters (AOWC) are envisioned to be part of future high-speed networks. In particular, they might replace optical-to-electrical-to-optical (OEO) wavelength translator units in optical crossconnects [1]. However, to be practical, AOWCs must be able to convert signals that have been degraded during transmission over reasonable distances. Tolerance to timing...

Impact - Generated Atmospheres over Titan , Ganymede ,

The competition between impact erosion and impact supply of volatiles to planetary atmospheres can determine whether a planet or satellite accumulates an atmosphere. In the absence of other processes (e.g., outgassing), we find either that a planetary atmosphere should be thick, or that there should be no atmosphere at all. The boundary between the two extreme cases is set by the mass and veloc...

Aluminium at terapascal pressures.

Studying materials at terapascal (TPa) pressures will provide insights into the deep interiors of large planets and chemistry under extreme conditions. The equation of state of aluminium is of interest because it is used as a standard material in shock-wave experiments and because it is a typical sp-bonded metal. Here we use density-functional-theory methods and a random-searching approach to p...
