In this Letter, we use a 0−π square-wave phase grating to shape 1350 nm and 1450 nm femtosecond pulses and create two intense lobes at the focus of a lens. We show that the relative phase between these two lobes (the 1st and −1st orders of diffr

We explore the growth temperature dependence of GaAs/AlGaAs core/shell nanowires (NW) grown by metal–organic chemical-vapor deposition (MOCVD) on (1 0 0) and (1 1 1)B GaAs substrates. In-situ calibration of the growth temperature allows for a syste

Information Visualization and Interface Culture

Autor: Greg J. Smith

This text seeks to contextualize the history of and discourse surrounding information visualization. It positions visualization in relation to broader 20th century visual culture and addresses the evolution of the interface as a ubiquitous tool and t
