Bohmian Histories and Decoherent Histories

The predictions of the Bohmian and the decoherent (or consistent) histories formulations of the quantum mechanics of a closed system are compared for histories — sequences of alternatives at a series of times. For certain kinds of histories, Bohmian mechanics and decoherent histories may both be formulated in the same mathematical framework within which they can be compared. In that framework, ...

Premonitory patterns of seismicity months before a large earthquake: five case histories in Southern California.

This article explores the problem of short-term earthquake prediction based on spatio-temporal variations of seismicity. Previous approaches to this problem have used precursory seismicity patterns that precede large earthquakes with "intermediate" lead times of years. Examples include increases of earthquake correlation range and increases of seismic activity. Here, we look for a renormalizati...

The Floras of Southern and Tropical Southeastern Yunnan Have Been Shaped by Divergent Geological Histories

The southern and tropical southeastern regions of the Yunnan Province in southwestern China have similar monsoonal climates and lowland tropical rain forest vegetations. The floras of both regions are dominated by tropical floristic elements (78.3% in southern Yunnan and 68.83% in southeastern Yunnan), and both belong to the Indo-Malaysian flora at the northern margin of tropical Asia. However,...

Natural histories

And because it is surrounded by an array of 60,000 photo-voltaic cells, the academy will produce more than five per cent of its electricity and overall use around a third less energy than the maximum allowed by San Francisco's already strict laws. " We could have thought of a different solution for the roof without plants and birds, " says Piano. " But the green roof is about a new spirit for t...
