Coordinating cell polarization and morphogenesis through mechanical feedback. [PDF]

open access: yesPLoS 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 ...

A Mechanical Feedback Classification of Linear Mechanical Control Systems [PDF]

open access: yesApplied Sciences, 2021
We give a classification of linear nondissipative mechanical control system under mechanical change of coordinates and feedback. First, we consider a controllable case that is somehow a mechanical counterpart of Brunovský classification, then we extend ...

Optical Coherent Feedback Control of a Mechanical Oscillator [PDF]

open access: yesPhysical Review X, 2023
Feedback is a powerful and ubiquitous technique both in classical and quantum system control. Its standard implementation relies on measuring the state of a system, processing the classical signal, and feeding it back to the system.

Patterned mechanical feedback establishes a global myosin gradient [PDF]

open access: yesNature 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

Mechanical feedback coordinates cell wall expansion and assembly in yeast mating morphogenesis. [PDF]

open access: yesPLoS Computational Biology, 2018
The shaping of individual cells requires a tight coordination of cell mechanics and growth. However, it is unclear how information about the mechanical state of the wall is relayed to the molecular processes building it, thereby enabling the coordination

Excitable dynamics driven by mechanical feedback in biological tissues [PDF]

open access: yesCommunications Physics
Pulsatory activity patterns, driven by mechanochemical feedback, are prevalent in many biological systems. However, the role of cellular mechanics and geometry in the propagation of pulsatory signals remains poorly understood.

Synthesis of nonlinear elastic couplings on the basis of modified kinematic graphs

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2017
In this work the analytical research of existing elastic couplings with linear mechanical feedback and synthesis was carried out taking into account passive elastic couplings with nonlinear mechanical feedback.

A Markov chain Monte Carlo model of mechanical-feedback-driven progressive apical constrictions captures the fluctuating collective cell dynamics in the Drosophila embryo

open access: yesFrontiers in Physics, 2022
Communication via mechanical stress feedback is believed to play an important role in the intercellular coordination of collective cellular movements. One such movement is ventral furrow formation (VFF) in the Drosophila melanogaster embryo.

Modeling Interactions among Migration, Growth and Pressure in Tumor Dynamics

open access: yesMathematics, 2021
What are the biomechanical implications in the dynamics and evolution of a growing solid tumor? Although the analysis of some of the biochemical aspects related to the signaling pathways involved in the spread of tumors has advanced notably in recent ...

Prediction of the time constant of small-scale concentrated solar CHP plants [PDF]

open access: yesE3S Web of Conferences, 2021
The operation of a power plant based on solar energy can vary significantly with time because of the intrinsic intermittency of the energy resource.
