In this paper we study the null-controllability of a beam equation with hinged ends and structural damping, the damping depending on a positive parameter. We prove that this system is exactly null controllable in arbitrarily small time. This result is proven using a combination of Ingham-type inequalities, adapted for complex frequencies, and exponential(More)
Stress activates the hypothalamic-pituitary-adrenocortical (HPA) axis and can suppress pulsatile luteinizing hormone (LH) secretion, resulting in reproductive dysfunction. The histocompatible inbred Fischer and Lewis rat strains exhibit marked phenotypic differences in the activity of the HPA axis, the former being more reactive. Using Fischer, Lewis and(More)
