Using this modelling approach, it is possible to separate the variation in capture rate due to a component which varies over a short time scale (activity) from variation due to a component which varies over a longer time scale (density) without a priori assumptions about its exact shape.
For the long-time scale component, if the conjunctive PF-CF happens regularly with a specific ISI, the PC-IN population learns to modulate the PCs' firing profiles at the time of the expected CF signal, due to the increased long-time scale activities of the PC-IN pairs.
Conceptual design models are described and discussed considering the long-time scale activity of spent nuclear fuel or high level waste.
On a short-term time scale, human activities will play a more important role in the modification and evolution of the ECWEs through direct exploitation of and interference with the structure and biogeochemical processes of the ECWEs.
Furthermore, we plan to incorporate an absolute time scale of activity by incorporating divergence data of elements.
On an evolutionary time scale, RTE activity has contributed hugely to the evolution of mammalian genomes [ 61- 64], and when attempting to understand the diversity of present eukaryotic life it is essential to include the history and activity of RTEs.
Initiated at the same time scale, transcriptional activity is adjusted, but due to the multiple subsequent steps of transcript accumulation, translation and assembly, the response is somewhat delayed compared to the first and second mechanism [ 3].
On short time scales, plague activity in the established foci is mainly determined by the abundance of rodent hosts and vectors, but bacterial evolution can be rapid and respond to changes in host availability and susceptibility as well as transmission rate and even seasonality [ 2- 4].
This 90-day measurement period is not long compared with the time scale of volcanic activity.
Time scale of the activity is dominated by the 21-year half-life of 210Pb.
In Definition 1, the network ISI distribution is fitted with a bi-exponential function, leading to two characteristic time scales: the short time scale corresponding to the activity during the bursts, and the long time scale to the inter-burst activity.
