TL;DR: A safety guideline is derived that would impose a precise upper bound on the cumulative exposure time, the product of the number of occupants and their time in an enclosed space, and the infectiousness of the respiratory aerosols is estimated from available data.

TL;DR: In this article, the authors presented the results of a combined experimental and theoretical investigation of the interactions of walking droplets, and delimit experimentally the different regimes for an orbiting pair of identical walkers and extend the theoretical model of Oza et al. in order to rationalize their observations.

TL;DR: In this article, the rough integument of water-walking arthropods is demonstrated to be responsible for their propulsive forces while retaining their water-repellency, and they demonstrate through a series of experiments that their tilted, flexible hairs interact with the free surface to generate directionally anisotropic adhesive forces that facilitate locomotion.

TL;DR: In this paper, a combined experimental and theoretical study of the interaction of walking droplets with a submerged planar barrier is presented, where the observed behaviour is captured by simulations based on a theoretical model that treats the boundaries as regions of reduced wave speed, and rationalized in terms of momentum considerations.

TL;DR: The walking droplet's horizontal motion is described by an integro-differential trajectory equation, which is found to admit steady orbital solutions and predictions for the dependence of the orbital radius and frequency on the strength of the radial harmonic force field agree favorably with experimental data.
