In a question about 2D oscillation trajectories ( Ambrose, 2007 ), the idea of a larger amplitude being related to a larger period was investigated again and it was again detected in many...

A schematic picture illustrates the idea of frequency-adaptive metadynamics (FAMetaD) to calculate the transition times. (a) FAMetaD fills the free energy basin with a high frequency at the beginning of the simulation, but switches to a low frequency when the system evolves close to the transition state regions. (b) Shows a typical trajectory of the bias deposition frequency, which changes on-the-fly with respect to simulation time in a FAMetaD run.

(b) Illustration of (i) bulk and (ii) surface micromachining processing steps forming suspended MCs. In bulk micromachining, the MC structure is directly etched into the wafer, which acts as the sacrificial layer, while in the surface micromachining, the wafer acts as the support and the sacrificial layer, typically SiO2, is fabricated directly on the wafer.
