An ensemble Kalman filter for statistical estimation of physics constrained nonlinear regression models

JOURNAL OF COMPUTATIONAL PHYSICS, 257, 782–812.

By: J. Harlim*, A. Mahdi n & A. Majda*

author keywords: Ensemble Kalman filter; Nonlinear regression models; Parameter estimation of stochastic differential equations; Multi-level models
TL;DR: A new finite ensemble Kalman filtering algorithm is developed for estimating the state, the linear and nonlinear model coefficients, the model and the observation noise covariances from available partial noisy observations of the state. (via Semantic Scholar)

Structural Identifiability of Viscoelastic Mechanical Systems

PLOS ONE, 9(2).

By: A. Mahdi n, N. Meshkat n & S. Sullivant n 

Contributors: A. Mahdi n, N. Meshkat n & S. Sullivant n 

MeSH headings : Algorithms; Arteries / pathology; Blood Pressure; Computer Simulation; Elasticity; Endothelium, Vascular / pathology; Humans; Models, Cardiovascular; Stress, Mechanical; Viscosity
TL;DR: A very simple characterization of both local and global structural identifiability based on identifiable tables is proposed, with the purpose of providing a guideline for constructing arbitrarily complex, identifiable spring-dashpot networks. (via Semantic Scholar)

Center conditions and cyclicity for a family of cubic systems: Computer algebra approach

MATHEMATICS AND COMPUTERS IN SIMULATION, 87, 55–67.

By: B. Fercec * & A. Mahdi n

author keywords: Cyclicity; Limit cycles; Center-focus problem
TL;DR: Using methods of computational algebra, an upper bound for the cyclicity of a family of cubic systems is obtained and the problem of nonradicality of the associated Bautin ideal is overcame by moving from the ring of polynomials to a coordinate ring. (via Semantic Scholar)

Modeling the Afferent Dynamics of the Baroreflex Control System

PLoS Computational Biology, 9(12), e1003384.

By: A. Mahdi n, J. Sturdy n, J. Ottesen * & M. Olufsen n

Ed(s): J. Arciero

MeSH headings : Baroreflex / physiology; Humans; Models, Biological
TL;DR: The modeling framework for predicting baroreceptor firing rate as a function of blood pressure is developed and it is shown that nonlinear dependence of firing rate on pressure can be accounted for by taking into account the nonlinear elastic properties of the artery wall.
