This paper is concerned with the stability of second-order linear time-varying systems.By utilizing the Lyapunov approach, a generally uniformly asymptotic stability criterion is obtained by adding the system matrices into the quadratic Lyapunov candidate function.In the case of the derivative of the Lyapunov candidate function is semi-positive def
To counterbalance the stakes of globalization and generalized competition, territories are compelled to build and manage their territorial attractiveness which is, often, driven by a comparative or even a differentiating advantage.Aware of these issues, the actors of the city of Rabat have undertaken territorialized actions.Indeed, the built fabric

Summary: The flowers of angiosperm species typically contain specialized conical cells.Although substantial Star Washer progress has been achieved regarding the mechanisms underlying flower development, little is known about how petal cells achieve final conical shape.Here, we use 8-hydroxypyrene-1,3,6-trisulfonic acid trisodium salt (HPTS) as a fl
