Is the squeezing of relic gravitational waves produced by inflation detectable? [PDF]

, 1999
Grishchuk has shown that the stochastic background of gravitational waves produced by an inflationary phase in the early Universe has an unusual property: it is not a stationary Gaussian random process. Due to squeezing, the phases of the different waves

Permutation Complexity and Coupling Measures in Hidden Markov Models

Entropy, 2013
Recently, the duality between values (words) and orderings (permutations) has been proposed by the authors as a basis to discuss the relationship between information theoretic measures for finite-alphabet stationary stochastic processes and their ...

Permutation Complexity via Duality between Values and Orderings

, 2011
We study the permutation complexity of finite-state stationary stochastic processes based on a duality between values and orderings between values.

Extreme Value Laws for sequences of intermittent maps [PDF]

, 2016
We study non-stationary stochastic processes arising from sequential dynamical systems built on maps with a neutral fixed points and prove the existence of Extreme Value Laws for such processes.

Summing Modulo 2 of Stationary Binary Stochastic Processes

IEEE Access
In the paper, we analyze the properties of the stochastic process obtained as the result of summing modulo 2 without carry of a finite number of stationary binary stochastic processes, some of which do not satisfy the independence condition.

Universal Kriging Prediction of nonstationary Spatial Stochastic Process [PDF]

المجلة العراقية للعلوم الاحصائية, 2010
Spatial Stochastic processes are often divided into two types that are stationary spatial stochastic processes and other nonstationary. In most practical applications the processes are nonstationary .Prediction of these processes are performed by ...

Nanodiamond‐Based Quantum Sensing Reveals Changes in Endo‐Lysosomal Activity of Stimulated Cardiac Fibroblasts in a Cellular Fibrosis Model

Advanced Functional Materials, EarlyView.
Quantum sensing reveals intricate patterns linking endo‐lysosomal maturation to cardiac fibrosis progression, highlighting complexity in cellular remodeling. This study investigates fibroblast‐to‐myofibroblast transition under cell aging, stiffness, and TGF‐β stimulation, comparing nanodiamond uptake, endo‐lysosomal dynamics, and free radical ...
