An approach to periodic, time-varying parameter estimation using nonlinear filtering
Inverse Problems, 34(10), 105005.
author keywords: time-varying parameter estimation; periodic structure; nonlinear filtering; ensemble Kalman filter (EnKF); FitzHugh-Nagumo; measles transmission
TL;DR:
An approach to estimating periodic, time-Varying parameters that imposes periodic structure by treating the time-varying parameter as a piecewise function with unknown coefficients is presented, allowing the resulting parameter estimate more flexibility in shape than prescribing a specific functional form to model its behavior.

Tissue self-organization underlies morphogenesis of the notochord
author keywords: zebrafish; notochord; vacuolated cells; packing; self-organization
MeSH headings : Animals; Cell Count; Embryonic Development; Models, Biological; Morphogenesis; Notochord / embryology; Zebrafish / embryology
TL;DR:
It is concluded that self-organization underlies morphogenesis of the vertebrate notochord, a conserved axial structure that in vertebrates serves as a hydrostatic scaffold for embryonic axis elongation and, later on, for proper spine assembly.

author keywords: Uncertainty Quantification; PZT Bimorph; Modeling; Surrogate; Homogenized Energy Model
TL;DR:
A high-fidelity model for a PZT bimorph actuator used for micro-air vehicles, which includes the Robobee is developed using the homogenized energy model (HEM) framework, which quantifies the nonlinear, hysteretic, and rate-dependent behavior inherent to PzT in dynamic operating regimes.

JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA, 144(2), 709–719.

TL;DR:
In considering the mixed-mode-dependent state feedback controller, both H∞ stochastic stability analysis for closed-loop system with completely accessible transition rates and uncertain transition rates are investigated and the problem of designing state feedback controllers such that the estimate of the domain of attraction is enlarged is formulated and solved as an optimization problem with LMI constraints.
