Effects of head loss, surface tension, viscosity and density ratio on the Kelvin-Helmholtz instability in different types of pipelines

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 424 ()

We report the effects of head loss, surface tension, viscosity and density ratio on the Kelvin-Helmholtz instability (KHI) in two typical pipelines, i......

Expected exit time for time-periodic stochastic differential equations and applications to stochastic resonance

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 417 ()

In this paper, we derive a parabolic partial differential equation for the expected exit time of non-autonomous time-periodic non-degenerate stochasti......

Explicit formulae for the peak time of an epidemic from the SIR model. Which approximant to use?

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 425 ()

An analytic evaluation of the peak time of a disease allows for the installment of effective epidemic precautions. Recently, an explicit analytic, app......

Evolutionary dynamics of cooperation in the N-person stag hunt game

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 424 ()

In this paper, we consider the N-person stag hunt game based on the two-person stag hunt game and assume that the payoff of successful stag hunters is......

The robust inverse scattering method for focusing Ablowitz-Ladik equation on the non-vanishing background

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 424 ()

In this paper, we consider the robust inverse scattering method for the Ablowitz-Ladik (AL) equation on the non-vanishing background, which can be use......

Mathematical formulation of a dynamical system with dry friction subjected to external forces

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 421 ()

We consider the response of a one-dimensional system with friction. Shaw (1986) introduced the set up of different coefficients for the static and dyn......

Non-parametric probabilistic load flow using Gaussian process learning

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 424 ()

The load flow problem is fundamental to characterize the equilibrium behavior of a power system. Uncertain power injections such as those due to deman......

About the robustness of 1d cellular automata revising their temporal entropy

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 425 ()

Complimentary to existing description methods of one-dimensional cellular automata dynamics the present study proposes a new 'micro-historicizing' app......

Enhanced energy harvesting using time-delayed feedback control from random rotational environment

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 422 ()

Motivated by improving performance of a bi-stable vibration energy harvester (VEH) from the viewpoint of vibration control, the time-delayed feedback ......

Riemann-Hilbert approach to the modified nonlinear Schrodinger equation with non-vanishing asymptotic boundary conditions

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 417 ()

The modified nonlinear Schrodinger (NLS) equation was proposed to describe the nonlinear propagation of the Alfven waves and the femtosecond optical p......

Association between COVID-19 cases and international equity indices

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 417 ()

This paper analyzes the impact of COVID-19 on the populations and equity markets of 92 countries. We compare country-by-country equity market dynamics......

Epidemic models with discrete state structures

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 422 ()

The state of an infectious disease can represent the degree of infectivity of infected individuals, or susceptibility of susceptible individuals, or i......

Dynamics of the Tyson-Hong-Thron-Novak circadian oscillator model

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 420 ()

We study the dynamics of a circadian oscillator model proposed by Tyson, Hong, Thron and Novak. This model describes a molecular mechanism for the cir......

Trends in COVID-19 prevalence and mortality: A year in review

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 425 ()

This paper introduces new methods to study the changing dynamics of COVID-19 cases and deaths among the 50 worst-affected countries throughout 2020. F......

Explicit formulae for the peak time of an epidemic from the SIR model

期刊: PHYSICA D-NONLINEAR PHENOMENA, 2021; 422 ()

Reducing the peak time of an epidemic disease in order for slowing down the eventual dynamics and getting prepared for the unavoidable epidemic wave i......
