Ion Acceleration—Target Normal Sheath Acceleration*

Energetic ions have been observed since the very first laser-plasma experiments. Their origin was found to be the charge separation of electrons heated by the laser, which transfers energy to the ions accelerated in the field. The advent of ultra-intense lasers with pulse lengths in the femtosecond regime resulted in the discovery of very energetic ions with characteristics quite different from...

Wave Detection in Acceleration Plethysmogram

OBJECTIVES Acceleration plethysmogram (APG) obtained from the second derivative of photoplethysmography (PPG) is used to predict risk factors for atherosclerosis with age. This technique is promising for early screening of atherosclerotic pathologies. However, extraction of the wave indices of APG signals measured from the fingertip is challenging. In this paper, the development of a wave detec...

Breaking the Wave of Enthusiasm?

The natural history of all substantial innovative medical procedures generally follows the same archetype. A new, potentially revolutionary treatment approach for a certain disease is introduced and initial first-in-men, feasibility, and safety studies are conducted by expert operators in highly specialized centers and selected patients. Given promising initial results, this triggers a wave of ...
