The engineering principles of combining a transcriptional incoherent feedforward loop with negative feedback

Journal of Biological Engineering, 2019
Background Regulation of gene expression is of paramount importance in all living systems. In the past two decades, it has been discovered that certain motifs, such as the feedforward motif, are overrepresented in gene regulatory circuits.

A noise barrier using hybrid ANC system

Nihon Kikai Gakkai ronbunshu, 2014
In this paper, in order to improve the low frequency noise insulation performance of a noise barrier, a new type of hybrid active noise control (ANC) system is proposed. The proposed system is a combination of feedforward and feedback controller.

Neural networks for modelling and control of a non-linear dynamic system [PDF]

, 1992
The authors describe the use of neural nets to model and control a nonlinear second-order electromechanical model of a drive system with varying time constants and saturation effects. A model predictive control structure is used.

Visual Recovery Reflects Cortical MeCP2 Sensitivity in Rett Syndrome

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Rett syndrome (RTT) is a devastating neurodevelopmental disorder with developmental regression affecting motor, sensory, and cognitive functions. Sensory disruptions contribute to the complex behavioral and cognitive difficulties and represent an important target for therapeutic interventions.
