The effect of stiff substrates on the collective migration of A549 cells

open access: yesJournal of Biomechanical Science and Engineering, 2023
The Young’s modulus of normal lung tissues ranges from 1 to 5 kPa, whereas fibrotic or lung tumor tissues can be ~30 times stiffer. However, the lung parenchyma microscopically consists of various tissues, and cancer cells in tumors contact stiff ...

Effective Distance for Vortex Generators in High Subsonic Flows

open access: yesAerospace, 2023
Vortex generators (VGs) are a passive method by which to alleviate boundary layer separation (BLS). The device-induced streamwise vortices propagate downstream. There is then lift-off from the surface and the vortex decays.

Distance effects in electrochemical micromachining [PDF]

open access: yesScientific Reports, 2016
AbstractConsidering exponential dependence of currents on double-layer voltage and the feedback effect of the electrolyte resistance, a distance effect in electrochemical micromachining is found, namely that both time constant and double-layer voltage depend on the separation of electrodes.

The distance effect in banking and trade [PDF]

open access: yesJournal of International Money and Finance, 2018
The empirical gravity literature finds geographical distance to be a large and growing obstacle to trade, contradicting the popular notion that globalization heralds "the end of geography". This distance puzzle disappears, however, when measuring the effect of cross-border distance relative to that of domestic distance (Yotov, 2012).
