Title
¬The influence of publication delays on the observed aging distribution of scientific literature
Source
Journal of the American Society for Information Science. 51(2000) no.2, S.158-165

Abstract
Observed aging curves are influenced by publication delays. In this article, we show how the 'undisturbed' aging function and the publication delay combine to give the observed aging function. This combination is performed by a mathematical operation known as convolution. Examples are given, such as the convolution of 2 Poisson distributions, 2 exponential distributions, a 2 lognormal distributions. A paradox is observed between theory and real data
