Vorticity regulates waves in fluids

A study by Politecnico di Torino published in the journal Physical Review E demonstrates that a wave in a fluid requires amplified vorticity and not only amplified energy in order to change the nature of the flow

Study develops a model enhancing particle beam efficiency

The use of particle accelerators is not confined to basic research in high-energy physics. Large-scale accelerators and gigantic instruments such as the Large Hadron Collider (LHC) are used for this purpose, but relatively ...

New tools reveal prelude to chaos

Picture a herd of sheep or cattle emerging from a shed or barn to graze a field. They head straight out of their digs to the pleasure of the pasture pretty much as one entity, but as the land opens up and the "grass gets ...

Electromagnetic water cloak eliminates drag and wake

Researchers have developed a water cloaking concept based on electromagnetic forces that could eliminate an object's wake, greatly reducing its drag while simultaneously helping it avoid detection.
