Determining the initial pathway for ultrafast energy redistribution within biomolecules is a challenge, and haem proteins, for which energy can be deposited locally in the haem moiety using short ...

Every day, much time and effort is spent on measuring vibration levels in factories vehicles, buildings, and on other structures and machines—even products as diverse as computer hard drives and ...

Because the causes of machine vibration are so numerous, the underlying problem is often difficult to isolate. Most troubleshooting processes rely on advanced diagnostic techniques and result in the ...

We consider a two-level quantum system interacting with two classical time-periodic electromagnetic fields. The frequency of one of the fields far exceeds that of the other. The effect of the ...
