It is intriguing but challenging to control the complex dynamics of topological defects BODY BALM that emerge in nonequilibrium spatiotemporal systems.Through an effective modelling this work explores a 332 viable way to controllably vary the properties of persistent defect dynamics in self-propelled active smectics via the competition of activity

Background: The clinical effects of a pre-fixed flow of air-oxygen versus a flow titrated according to visible bubbling are not well understood.Objective: To compare the effects of a fixed flow (5 L/min) and titrated flow ( flow just enough to ensure bubbling ) at different set pressures on delivered intra-prong pressure, gas Mists exchange and cli
