We generalize the collision term in the one-dimensional Boltzmann-Nordheim transport equation for quasiparticles that obey the Haldane exclusion statistics. For the equilibrium situation, this leads to the " golden rule " factor for quantum transitions. As an application of this, we calculate the density response function of a one-dimensional electron gas in a periodic potential, assuming that ...

A close reading of Hotelling's famous article on exhaustible resources reveals the following passage: 'If a mine-owner produces too rapidly, he will depress the price, perhaps to zero. If he produces too slowly, his profits, though larger, may be postponed farther into the future than the rate of interest warrants. Where is hisgolden mean? And how does this most profitable rate of production va...

In 2006, the Ministry of Defense of the Netherlands initiated a targeted agenda program for the World Congress on Disaster and Emergency Medicine in Amsterdam in 2007 (15WCDEM). The issue to be discussed was if there is one "golden" treatment and evacuation system that is applicable for different military and civilian situations. And, if there is not such a system, which parameters are importan...
