Magnetoconvection transient dynamics by numerical simulation [PDF]

The European Physical Journal E, 2017
We investigate the transient and stationary buoyant motion of the Rayleigh-Bénard instability when the fluid layer is subjected to a vertical, steady magnetic field. For Rayleigh number, Ra, in the range 103-106, and Hartmann number, Ha, between 0 and 100, we performed three-dimensional direct numerical simulations.

Long Chaotic Transients in Complex Networks

, 2004
We show that long chaotic transients dominate the dynamics of randomly diluted networks of pulse-coupled oscillators. This contrasts with the rapid convergence towards limit cycle attractors found in networks of globally coupled units. The lengths of the

Oscillatory transient regime in the forced dynamics of a spin torque nano-oscillator

, 2009
We demonstrate that the transient non-autonomous dynamics of a spin torque nano-oscillator (STNO) under a radio-frequency (rf) driving signal is qualitatively different from the dynamics described by the Adler model.

Non-back-drivable clutch based self-locking mechanism of prosthetic joint to improve manipulation stability

Frontiers in Bioengineering and Biotechnology
During activities of daily living (ADLs), the wrist is mainly engaged in positioning and directing the hand. Researches have demonstrated that restoring wrist mobility can significantly enhance the manipulation ability, reduce body distortion caused by ...

Fixation, transient landscape and diffusion's dilemma in stochastic evolutionary game dynamics

, 2011
Agent-based stochastic models for finite populations have recently received much attention in the game theory of evolutionary dynamics. Both the ultimate fixation and the pre-fixation transient behavior are important to a full understanding of the ...

Short-term memory by transient oscillatory dynamics in recurrent neural networks

Physical Review Research, 2021
Despite the significance of short-term memory in cognitive function, the process of encoding and sustaining the input information in neural activity dynamics remains elusive. Herein, we unveiled the significance of transient neural dynamics to short-term

Small quantum absorption refrigerator in the transient regime: time scales, enhanced cooling and entanglement

, 2015
A small quantum absorption refrigerator, consisting of three qubits, is discussed in the transient regime. We discuss time scales for coherent dynamics, damping, and approach to the steady state, and we study cooling and entanglement.

Transients, Metastability, and Neuronal Dynamics [PDF]

NeuroImage, 1997
This paper is about neuronal dynamics and how their special complexity can be understood in terms of nonlinear dynamics. There are many aspects of neuronal interactions and connectivity that engender the complexity of brain dynamics. In this paper we consider (i) the nature of this complexity and (ii) how it depends on connections between neuronal ...

Transient inconsistency between population density and fisheries yields without bycatch species extinction

Ecology and Evolution, 2020
Recent studies have demonstrated the great advantages of marine reserves in solving bycatch problems by maintaining the persistence (i.e., avoid extinction) of endangered species without sacrificing the fisheries yields of target species.
