Time structure, temporal correlation and coherence of chemosensory impulses propagated through both carotid nerves in cats
(1997)
In spontaneously breathing, pentobarbitone anesthetized cats, we recorded simultaneously the impulses in the chemosensory fibers of both carotid (sinus) nerves, to analyze the correlations between the frequencies of ...
Improving the shape of the cross-correlation function for leak detection in a plastic water distribution pipe using acoustic signals
(2017-12-01)
This paper is concerned with time delay estimation for the detection of leaks in buried plastic water pipes using the cross-correlation of leak noise signals. In some circumstances the bandwidth of over which the signal ...
Correlation Decay and Recurrence Asymptotics for Some Robust Nonuniformly Hyperbolic Maps
(2008)
We study a robust class of multidimensional non-uniformly hyperbolic transformations
considered by Oliveira and Viana (Ergod. Theory Dyn. Syst. 28:501–533, 2008).
For an open class of Hölder continuous potentials with small ...
The effects of resonances on time delay estimation for water leak detection in plastic pipes
(2018-04-28)
In the use of acoustic correlation methods for water leak detection, sensors are placed at pipe access points either side of a suspected leak, and the peak in the cross-correlation function of the measured signals gives ...
Evolution of multifractal cross-correlations between the Argentina MERVAL Index and international commodities prices
(Routledge Journals, Taylor & Francis Ltd, 2016-10)
We compute the auto-correlations and cross-correlations of the volatility time series of the Argentina MERVAL Index (the Buenos Aires Stock Exchange main index) and three agricultural commodities, in a multifractal context ...
Chaos signatures in the short and long time behavior of the Out-of-Time ordered correlator
(American Physical Society, 2018-11)
Two properties are needed for a classical system to be chaotic: exponential stretching and mixing. Recently, out-of-time order correlators were proposed as a measure of chaos in a wide range of physical systems. While most ...
Effect of interacting second- and third-order stimulus-dependent correlations on population-coding asymmetries
(American Physical Society, 2016-10)
Spike correlations among neurons are widely encountered in the brain. Although models accounting for pairwise interactions have proved able to capture some of the most important features of population activity at the level ...
A scaling limit for the cover time of the binary tree
(Academic Press Inc., 2021)
© 2021 Elsevier Inc.We consider a continuous time random walk on the rooted binary tree of depth n with all transition rates equal to one and study its cover time, namely the time until all vertices of the tree have been ...
Revisiting the decay of missing ordinal patterns in long-term correlated time series
(Elsevier Science, 2019-11-15)
We revisit the decay of missing ordinal patterns in long-term correlated time series. More precisely, a stretched exponential model is proposed to describe more appropriately how the number of missing ordinal patterns ...
