Abstract The connection between the Atlantic meridional overturning circulation (AMOC) and multidecadal variability (AMV) is inspected in a suite of pre‐industrial integrations from 6th phase Coupled Model Inter‐comparison Project (CMIP6), using change‐point detection method to identify different AMOC‐AMV co‐variability regimes. A key finding this study that models robustly simulate multi‐decad...

We study the effects of stochastic resetting on geometric Brownian motion (GBM), a canonical multiplicative process for non-stationary and non-ergodic dynamics. Resetting is sudden interruption process, which consecutively renews its show that, although renders GBM stationary, resulting remains non-ergodic. Quite surprisingly, effect pivotal in manifesting behavior. In particular, we observe th...

We present the first experimental determination of the time auto-correlation of magnetization in the nonstationary regime of a spin glass, and its quantitative comparison with the corresponding response, the magnetic relaxation function. These measurements were performed in a new experimental setup working as an absolute thermometer. Clearly, we observe a non-linear fluctuation-dissipation rela...

Abstract: The FitzHugh-Nagumo is a well-known neuronal model that describes the generation of spikes at the intracellular level. We study a stochastic version of the model from a probabilistic point of view. The hypoellipticity is proved, as well as the existence and uniqueness of the stationary distribution. The bi-dimensional stochastic process is β-mixing. The stationary density can be estim...

This paper presents a linear stability analysis of natural convection in a horizontal layer of a viscoelastic nanofluid. The Oldroyd B model was utilized to describe the rheological behavior of a viscoelastic nanofluid. The model used for the nanofluid incorporated the effects of Brownian motion and thermophoresis. The onset criterion for stationary and oscillatory convection was derived analyt...

Spherically symmetric transonic accretion of a fractal medium has been studied in both the stationary and the dynamic regimes. The stationary transonic solution is greatly sensitive to infinitesimal deviations in the outer boundary condition, but the flow becomes transonic and stable, when its evolution is followed through time. The evolution towards transonicity is more pronounced for a fracta...

Localized planar patterns arise in many reaction-diffusion models. Most of the paradigm equations that have been studied so far are two-component models. While stationary localized structures are often found to be stable in such systems, travelling patterns either do not exist or are found to be unstable. In contrast, numerical simulations indicate that localized travelling structures can be st...

Bargaining with reading habit is no need. Reading is not kind of something sold that you can take or not. It is a thing that will change your life to life better. It is the thing that will give you many things around the world and this universe, in the real world and here after. As what will be given by this health care provision and patient mobility health integration in the european union, ho...
