Probability distribution of residence times of grains in models of ricepiles [PDF]
, 2005 We study the probability distribution of residence time of a grain at a site, and its total residence time inside a pile, in different ricepile models. The tails of these distributions are dominated by the grains that get deeply buried in the pile.

Fractional diffusion modeling of ion channel gating [PDF]
, 2004 An anomalous diffusion model for ion channel gating is put forward. This scheme is able to describe non-exponential, power-law like distributions of residence time intervals in several types of ion channels.

Atmospheric residence time of CH3Br estimated from the junge spatial variability relation [PDF]
, 1998 The atmospheric residence time for methyl bromide (CH3Br) has been estimated as 0.8 +/- 0.1 years from its empirical spatial variability relative to C2H6, C2Cl4, CHCl3, and CH3Cl.

Process mapping of laser surface modification of AISI 316L stainless steel for biomedical applications [PDF]
, 2009 A 1.5-kW CO2 laser in pulsed mode at 3 kHz was used to investigate the effects of varied laser process parameters and resulting morphology of AISI 316L stainless steel. Irradiance and residence time were varied between 7.9 to 23.6 MW/cm2 and 50 to 167 µs
