Mechanically Programmable DNA Hydrogel Microparticles for 3D Cellular Systems
Advanced Materials, EarlyView.DNA hydrogel microparticles are designed to exhibit controllable viscoelasticity and stiffness across three orders of magnitude from 30Pa$30 \,\mathrm{Pa}$ to 6.5kPa$6.5 \,\mathrm{kPa}$. They are uptaken into fibroblast spheroids where they are actively remodeled by cellular forces depending on their mechanical properties.

The Analysis and Creation of Track Irregularities Using TRAKVU
, 1998 The accuracy of the results from a rail vehicle dynamic model is dependent on the realism of the track input to the model. An important part of the track input is the irregularities that exist on actual track.
Kramp, Kenneth P.
core
, 2019 A solution method for dynamic reliability of vehicle-track coupled systems considering the randomness of track irregularities is presented by combining the wheel-rail force prediction based iterative solution technique with the subset simulation (SS ...
