Epidemic propagation on complex networks has been widely investigated, mostly with invariant parameters. However, the process of epidemic propagation is not always constant. Epidemics can be affected by various perturbations and may bounce back to its original state, which is considered resilient. Here, we study the resilience of epidemics on networks, by introducing a different infection rate ...

The Interpolated Bounce-Back (IBB) method and Immersed-Boundary (IB) method are compared for fluid-solid boundary conditions in the Lattice Boltzmann Equation (LBE) in terms of their numerical accuracy and computational efficiency. We carry out simulations for the flow past a circular cylinder asymmetrically placed in the channel in two dimensions with the Reynolds number Re = 20 and 100, corre...

We investigate the spectral properties of the time-dependent linear transport equation with bounce-back boundary conditions. A fine analysis of the spectrum of the streaming operator is given and the explicit expression of the strongly continuous streaming semigroup is derived. Next, making use of a recent result from [1], we prove, via a compactness argument, that the essential spectrum of the...

INTRODUCTION The rate of return visits at urban emergency departments (EDs) has been reported as approximately 3% within 72 hours of discharge. However, the current literature does not indicate the rate of return visits for rural EDs. The purpose of this study was to determine the bounce-back rate at a rural ED and to characterize the visits. METHODS A retrospective chart review was performed...

The time evolution of pseudorapidity distributions of produced charged hadrons in d+Au collisions at √ sNN = 200 GeV is investigated. Results of a nonequilibrium-statistical Relativistic Diffusion Model with three sources are compared with a macroscopic ”bounce back” model that does not allow for statistical equilibration at large times, but instead leads to motion reversal. When compared to th...

Abstract We examine the immediate and bounce-back effects from six modern health crises that preceded Covid-19. Time-series models for a large cross-section of economies indicate real GDP growth falls by around 2 percentage points in affected relative to unaffected year outbreak. Bounce-back is rapid strong, especially when compared non-health crises. Unemployment less educated workers higher e...
