For a long time transverse and longitudinal optical forces are used for non-contact noninvasive manipulation of small individual particles. The following question arises: What is the impact these on ensemble thousand particles in continuous media? aim this work to find analytical expression radiation force potential densities creating from laser pulse propagating dielectric media. This allows u...

We show that the spectral flow due to a moving vortex is identical to the phase slippage process, and conclude that its evaluation confirms the results by the Berry's phase calculation of the Magnus force.

Fish keratocytes can generate rearward directed traction forces within front portions of the lamellipodium, suggesting that a retrograde flow of actin may also occur here but this was not detected by previous photoactivation experiments. To investigate the relationship between retrograde flow and traction force generation, we have transfected keratocytes with GFP-actin and used fluorescent spec...

We present a Direct Forcing (DF) approach for simulations of flows over moving bodies, on Cartesian grids, capable of reducing the amplitude of the force oscillations, by using a regularized approach.
