Do shocks last forever? Local persistency in economic time series
(2007)
While it is recognized that many macroeconomic time series are highly persistent over certain range, less persistent results are also found around very long horizons, indicating the existence of local or temporary persistency. ...
Quenched distributions for the maximum, minimum and local time of the Brox diffusion
(2021)
After leaving fixed the environment, which is called the quenchend case, we give explicitly the distribution function of the maximum and the minimum of the Brox diffusion at first time it reaches a barrier. We also give ...
The global non-entropic arrow of time: from global geometrical asymmetry to local energy flow
(Springer, 2009-03)
Since the nineteenth century, the problem of the arrow of time has been
traditionally analyzed in terms of entropy by relating the direction past-to-future to
the gradient of the entropy function of the universe. In this ...
Estimation of a measure of local correlation for independent samples and time series data
(Springer (India)Calcutta, 2013)
Different from measures of global dependence, measures of local dependence
evaluate the dependence along the support of the variables. The aim of
this paper is to study a measure of local dependence proposed by Bairamov,
Kotz ...
Study of a logistic equation with local and non-local reaction terms
(2016-06-01)
We examine a logistic equation with local and non-local reaction terms both for time dependent and steady-state problems. Mainly, we use bifurcation and monotonicity methods to prove the existence of positive solutions for ...
Impact Localization in Composites Using Time Reversal, Embedded PZT Transducers, and Topological Algorithms
(2020-03-17)
Time reversal is a powerful imaging processing technique that focuses waves at their original source using a single receiver transducer when diffusive wave field conditions are met. This has been successfully proved on ...
Tunneling time through a barrier using the local value of a time operator
(American Physical Soc, 2001-08-01)
A time for a quantum particle to traverse a barrier is obtained for stationary states by setting the local value of a time operator equal to a constant. This time operator, called the tempus operator because it is distinct ...
