Abstract
We find that intervals between successive drops from a leaky faucet
display scale-invariant, long-range anticorrelations characterized
by the same exponents of heart beat-to-beat intervals of healthy subjects.
This behavior is also confirmed by numerical simulations on lattice and it is
faucet-width- and flow-rate-independent. The histogram for the drop
intervals is also well described by a Levy distribution with
the same index for both histograms of healthy and diseased subjects. This
additional result corroborates the evidence for similarities between
leaky faucets and healthy hearts underlying dynamics.
