Feed-forward mortality rate model.

, 2022
a) Time-dependent C-index stratified vs age (points) and for all ages (line). Results are shown for the feed-mortality mortality rate model (purple), the DJIN network model with a recurrent neural network mortality rate shown in the main results (red ...

Increased co-contraction reaction during a surface perturbation is associated with unsuccessful postural control among older adults

BMC Geriatrics, 2022
Background As a strategy to maintain postural control, the stiffening strategy (agonist-antagonist co-contractions) is often considered dysfunctional and associated with poor physical capacity.

A mixed incoherent feed-forward loop allows conditional regulation of response dynamics. [PDF]

PLoS ONE, 2014
Expression of the SodA superoxide dismutase (MnSOD) in Escherichia coli is regulated by superoxide concentration through the SoxRS system and also by Fur (Ferric uptake regulator) through a mixed incoherent feed forward loop (FFL) containing the RyhB ...

Research on Feed Forward Adaptive-generalized Model Predictive Control for High-speed Train Automatic Operation

Kongzhi Yu Xinxi Jishu
High-speed automatic train operation (ATO) systems inherently exhibit strong nonlinearity and uncertainty. In view of the characteristics of nonlinearity and time-variability of high-speed train model parameters, this paper proposes a feed forward ...
