From Displacement to Angle: Diamond‐Based 3D Rotation Sensing for High‐Precision Cellular Force Measurement

open access: yesAdvanced Science, EarlyView.
Cellular forces are traditionally inferred from displacement measurements, which lack rotational information and are constrained by linear model assumptions. This work replaces displacement with rotational angle for the fundamental mechanical readout.

Boundary controllability and source reconstruction in a viscoelastic string under external traction [PDF]

open access: yes, 2013
Treatises on vibrations devote large space to study the dynamical behavior of an elastic system subject to known external tractions since usually a ``system'' is part of a chain of mechanisms which disturb the ``system'' for example due to the periodic ...
