Abstract

This paper constructs dynamical models and estimation algorithms for the concentration of target molecules in a fluid flow using an array of novel biosensors. Each biosensor is constructed out of protein molecules embedded in a synthetic cell membrane. The concentration evolves according to an advection-diffusion partial differential equation which is coupled with chemical reaction equations on the biosensor surface. By using averaging theory methods and the divergence theorem, an approximate model is constructed that describes the asymptotic behaviour of the concentration as a system of ordinary differential equations. The estimate of target molecules is then obtained by solving a nonlinear least squares problem. It is shown that the estimator is strongly consistent and asymptotically normal. An explicit expression is obtained for the asymptotic variance of the estimation error. As an example, the results are illustrated for a novel biosensor built out of protein molecules.

Abstract

The article presents a study focusing on strain-induced modulation of perpendicular magnetic anisotropy (PMA) in tantalum(Ta)/cobalt iron boron (CoFeB)/magnesium oxide (MgO) structures investigated by ferromagnetic resonance. The findings include strain-induced change in PMA extracted from the experimental ferromagnetic resonance (FMR) spectra, modulation of the PMA of an ultrathin CoFeB layer by voltage-induced strain and dependence of the effective damping constant as a function of strain.
