Numerical analysis of temperature fluctuation characteristics associated with thermal striping phenomena in the PGSFR

open access: yesNuclear Engineering and Technology, 2022
Thermal striping is a complex thermal–hydraulic phenomenon caused by fluid temperature fluctuations that can also cause high-cycle thermal fatigue to the structural wall of sodium-cooled fast reactors (SFRs).

Fluctuating hydrodynamics and mesoscopic effects of spatial correlations in dissipative systems with conserved momentum

open access: yesNew Journal of Physics, 2015
We introduce a model described in terms of a scalar velocity field on a 1D lattice, evolving through collisions that conserve momentum but do not conserve energy.

Neural control on multiple time scales: Insights from human stick balancing

open access: yesCondensed Matter Physics, 2006
The time-delayed feedback control mechanisms of the nervous system are continuously subjected to the effects of uncontrolled random perturbations (herein referred to as noise).

Bayesian experimental design and parameter estimation for ultrafast spin dynamics

open access: yesMachine Learning: Science and Technology, 2023
Advanced experimental measurements are crucial for driving theoretical developments and unveiling novel phenomena in condensed matter and materials physics, which often suffer from the scarcity of large-scale facility resources, such as x-ray or neutron ...

Dynamic Evolution Analysis of Stock Price Fluctuation and Its Control

open access: yesComplexity, 2018
This paper studies a simple dynamical system of stock price fluctuation time series based on the rule of stock market. When the stock price fluctuation system is disturbed by external excitations, the system exhibits obviously chaotic phenomena, and its ...

Fluctuations in strongly correlated electron systems

open access: yesResults in Physics, 2018
High transition temperature superconductors in cuprates exhibit the charge-density-wave fluctuations and the ferromagnetic time-reversal-symmetry-breaking fluctuation in the polar Kerr rotation experiments. We demonstrate that they share the same root of
