This paper presents an analysis on the appearance of limit cycles in planar Filippov system with two linear subsystems separated by a straight line.Under the restriction that the orbits with points Air Conditioner Filter in the sliding and escaping regions are not considered, we provide firstly a topologically equivalent canonical form of saddle-fo
In this study cardiac tissue is stimulated electrically through a small unipolar electrode.Numerical simulations Knits predict that around an electrode are adjacent regions of depolarization and hyperpolarization.Experiments have shown that during pacing of resting cardiac tissue the hyperpolarization is often inhibited.Our goal is to determine if
The growing use of artificial turf in place of natural turf in residential, recreational and commercial settings has raised concerns regarding its potential impact on human health.A systematic review of databases revealed 5673 articles of which, 30 were deemed eligible.Those performing total concentration analyses, bioaccessibility analyses or huma
