Coordinating cell polarization and morphogenesis through mechanical feedback.
PLoS Computational Biology, 2021 Many cellular processes require cell polarization to be maintained as the cell changes shape, grows or moves. Without feedback mechanisms relaying information about cell shape to the polarity molecular machinery, the coordination between cell ...

Feedback Integrators for Mechanical Systems with Holonomic Constraints
Sensors, 2022 The feedback integrators method is improved, via the celebrated Dirac formula, to integrate the equations of motion for mechanical systems with holonomic constraints so as to produce numerical trajectories that remain in the constraint set and preserve ...

Modeling and characteristic analysis of pneumatic positioning system with mechanical feedback
Nihon Kikai Gakkai ronbunshu, 2018 In recent years, electronic control has become mainstream of pneumatic control systems. But pneumatic positioning systems have advantages such as explosion proof, operable even at power failure, simple structure, easier maintenance, and low price ...

Clickers in a Flipped Lab; feedback to enhance engagement in first year Science. [PDF]
, 2017 Anecdotal evidence from lecturers engaged in teaching practical’s is that there is very little if any interaction from the students with the pre-lab reading resources as posted on Moodle or in the laboratory manuals provided at the beginning of the

Patterned mechanical feedback establishes a global myosin gradient
Nature Communications, 2022 How does DNA encode shape? Here, via in toto light sheet microscopy and optogenetic control of cellular forces, the authors show that spatially patterned mechanical feedback loops establish the cytoskeletal patterns driving axis elongation tissue flow in

Sliding mode learning control for uncertain mechanical system: A dynamic output feedback approach
Measurement + Control, 2020 In this article, a dynamic output feedback based sliding mode learning control is proposed for uncertain mechanical system. After giving the model of uncertain mechanical system, the uncertainty and disturbance of it are discussed and they are assumed to

Multimode cold-damping optomechanics with delayed feedback
Physical Review Research, 2020 We investigate the role of time delay in cold-damping optomechanics with multiple mechanical resonances. For instantaneous electronic response, it was recently shown by C. Sommer and C. Genes [Phys. Rev. Lett.

A Pneumatic Proportional Constant Flow Valve With Mechanical Feedback
IEEE Access, 2022 To make the flow rate of a gas valve insensitive to changes in inlet pressure and to achieve proportional constant flow characteristics, a proportional constant flow valve is proposed, which is mechanically fed back by the pressure of the flowing gas ...
