Mr. Chairman, Mr. Stark, and distinguished members of the Committee: Thank you for inviting me to share my views on the growing phenomenon of physicians providing care outside of insurance. This is a timely hearing and I hope to bring a different perspective to the Committee's consideration of the crucial role of health insurance in protecting Americans' health and financial well-being. The vie...

In the current study the influence of weight percentage of HIPS, weight percentage of CNT and hardener content on damping 1st and damping 2nd properties of epoxy/HIPS/CNT hybrid composite wase valuated. Mixture design methodology was employed to generate mathematical models for predicting damping 1st and damping 2nd behaviors of new mentioned hybrid nanocomposite as function of physical factors...

We construct global BV solutions to the Cauchy problem for the damped p-system, under initial data with distinct end-states. The solution will be realized as a perturbation of its asymptotic profile, in which the specific volume satisfies the porous media equation and the velocity obeys the classical Darcy law for gas flow through a porous medium.

In this paper we consider the following Timoshenko system φtt − (φx + ψ)x = 0, (0, 1)× (0,+∞) ψtt−ψxx + ∫ t 0 g(t−τ)(a(x)ψx(τ))xdτ +φx +ψ+b(x)h(ψt) = 0, (0, 1)×(0,∞) with Dirichlet boundary conditions where a, b, g, and h are specific functions. We establish an exponential and polynomial decay results. This result improves and generalizes some existing results in the literature.

This paper presents an alternative solution to the vibration problem in civil engineering structures. This kind of structures are characterized by the uncertainties of the parameters that describe their dynamics, such as stiffness and damping coefficients. Moreover, the actuators used to mitigate the vibrations caused by earthquakes are usually nonlinear devices with frictional or hysteretic dy...
