In this article Danny T Quah examines how, when an economy grows, its patterns of production and consumption systematically change. He describes one such large-scale evolution, namely, the increasing weightlessness of aggregate output across advanced economies. In all fast-growing successful countries, growth in information technology has contributed positively both to increasing weightlessness...

We know that, at least in the short term, a rise in temperature exponentially increases the emission rates of most biogenic volatile organic compounds (BVOCs). It does so by enhancing the enzymatic activities of synthesis, by raising the BVOC vapour pressure, and by decreasing the resistance of the diffusion pathway (Tingey et al., 1991). BVOC emissions are thus expected to increase strongly wi...

Autonomous mobile robots need to detect potential failures reliably and react appropriately. Due to uncertainties about the robots and their environment, it is extremely difficult to design reliable systems from the start. Instead, we advocate the structured control methodology, in which one starts with plans that work in nominal situations, and then incrementally adds reactive behaviors to han...
