Web1 day ago · Here we develop an imaging-based confined migration device that provides stiffness gradient for cell migration. By tracking live cell trajectory and analyzing the directionality T cells and neutrophils, we observe that amoeboid cells can durotax. We further delineate the underlying mechanism to involve non-muscle myosin IIA (NMIIA) … http://awibisono.github.io/2016/06/13/gradient-flow-gradient-descent.html

WebJan 31, 2024 · Here, we study theoretically how stiffness gradients influence droplet growth and arrangement. We show that stiffness gradients imply concentration gradients in the … WebMay 9, 2024 · Conclusion: This study is notable in its report of durotaxis of cells in response to a stiffness gradient slope, which is greater than an order of magnitude less than reported elsewhere in the literature, suggesting Schwann cells are highly sensitive detectors of mechanical heterogeneity. black root tea

When f is convex (and differentiable), it turns out we can prove an explicit convergence rate. Theorem: Whenever f is convex, gradient flow has convergence rate f(Xt) − f(x ∗) ≤ ‖X0 − x ∗ ‖2 t = O(1 t) Proof: Consider the “energy functional” black root tonic atlanta
