Wave dynamics on toroidal surface [PDF]
Optics Express, 2018 Wave dynamics on curved surfaces has attracted growing attention due to its close resemblance to the warped space time governed by general relativity. It also opens up opportunities for designing functional optical devices such as geodesic lenses. In this work we study the wave dynamics on the surface of a torus, a shape of considerable interest due to

Stochastic termination of spiral wave dynamics in cardiac tissue. [PDF]
Front Netw Physiol, 2022 Rotating spiral waves are self-organized features in spatially extended excitable media and may play an important role in cardiac arrhythmias including atrial fibrillation (AF).

Impact of US vaccination strategy on COVID-19 wave dynamics. [PDF]
Sci Rep, 2021 We employ the epidemic Renormalization Group (eRG) framework to understand, reproduce and predict the COVID-19 pandemic diffusion across the US. The human mobility across different geographical US divisions is modelled via open source flight data ...

A review on partial-wave dynamics with chiral effective field theory and dispersion relation [PDF]
Reports on progress in physics. Physical Society, 2020 The description of strong interaction physics of low-lying resonances is out of the valid range of perturbative QCD. Chiral effective field theories (EFTs) have been developed to tackle the issue.

A high‐accuracy global prognostic model for the simulation of Rossby and gravity wave dynamics
Quarterly Journal of the Royal Meteorological Society, 2021 A model for studying Transient Inertia–Gravity And Rossby wave dynamics (TIGAR) is introduced. The presented horizontal component of the model solves the nonlinear rotating shallow‐water equations on the sphere using Hough harmonics.

On the compact wave dynamics of tensegrity beams in multiple dimensions [PDF]
Nonlinear dynamics, 2019 This work presents a numerical investigation on the nonlinear wave dynamics of tensegrity beams in 1D, 2D, and 3D arrangements. The simulation of impact loading on a chain of tensegrity prisms and lumped masses allows us to apply on a smaller scale ...

Faraday pilot-wave dynamics in a circular corral
Journal of Fluid Mechanics, 2020 A millimetric droplet of silicone oil may bounce and self-propel on the free surface of a vertically vibrating fluid bath due to the droplet’s interaction with its accompanying Faraday wave field.
