Abstract. This paper presents a new observability estimate for parabolic equations in Ã— (0, T ), where is a convex domain. The observation region is restricted over a product set of an openâ€¦ (More)

We provide a polynomial decay rate for the energy of the wave equation with a dissipative boundary condition in a cylindrical trapped domain. A new kind of interpolation estimate for the waveâ€¦ (More)

This work concerns with the existence of the time optimal controls for some linear evolution equations without the a priori assumption on the existence of admissible controls. Both global and localâ€¦ (More)

This talk describes some applications of two kinds of observation estimate for the wave equation and for the damped wave equation in a bounded domain where the geometric control condition of C.â€¦ (More)

We prove a polynomial energy decay for the Maxwellâ€™s equations with Ohmâ€™s law in partially cubic domains with trapped rays. We extend the results of polynomial decay for the scalar damped waveâ€¦ (More)

OBJECTIVE
Psoas muscle area (PMA) is a validated surrogate for muscle mass that can be easily measured from a clinical CT scan. This study sought to determine whether PMA was associated withâ€¦ (More)
