Averaged number of visits.
We introduce a new indicator for dynamical systems, namely the averaged number of visits, to estimate the frequency of visits in small regions when a map is iterated up to the inverse of the measure of this region. We compute this quantity analytically and numerically for various systems and we show that it depends on the ergodic properties of the systems and on their topological properties, su...
متن کاملMean number of visits to sites in Levy flights.
Formulas are derived to compute the mean number of times a site has been visited during symmetric Levy flights. Unrestricted Levy flights are considered first, for lattices of any dimension: conditions for the existence of finite asymptotic maps of the visits over the lattice are analyzed and a connection is made with the transience of the flight. In particular it is shown that flights on latti...

متن کاملDefinition of hypertension: the impact of number of visits for blood pressure measurement.
INTRODUCTION A diagnosis of hypertension should be based on multiple blood pressure (BP) measurements, taken on at least two separate occasions. We aimed to assess the impact of considering different criteria for a definition of hypertension, based on number of visits for blood pressure measurement, on estimates of hypertension prevalence, awareness, treatment and control, and on its associatio...
