Even if the precise occurrence of spontaneous IPH remains uncertain, mostly because a few studies are available, incidence of retroperitoneal bleeding in patients undergoing anticoagulation has been reported ranging from 0.1 to 0.6 % [1].
The continuous and accurate monitoring of radon concentration in air is realised by observing the alpha and beta particles produced by the decay of 222Rn and its daughters and tag each of them with a precise occurrence time.
Seen as an auspiciously magickal time due to its precise occurrence between the autumnal equinox and winter solstice, Samhain was associated with the point between life and death.
The minos integration site of transgenic line AsML10 was sequenced and the precise occurrence of minos-mediated integration confirmed (not shown, EMBL accession numbers AJ496323 and AJ496324).
However, the precise occurrence of outbreaks in historical public health surveillance data is often not well-defined, and historical surveillance data generally contain few well-documented outbreaks which can be used to test algorithms.
Although some anticipatory measures against intensifying disturbance regimes can be taken (e.g., increasing the stability of individual trees and forest stands), the precise occurrence and impact of a disturbance event remains unpredictable.
