Abstract Methods to follow in real time complex processes occurring along living cell membranes such as cell permeabilization are rare. Here, the terahertz spectroscopy reveals early events in plasma membrane alteration generated during photodynamic

Spatial distribution of air bubbles created by an imping water jet into a free water surface

Publikováno v: Emergent Scientist. 6:3

In this paper we study the rise to the surface, radial motion and disappearance of the bubbles created by a water jet pouring into a container, in particular their density at the surface as a function of the impact velocity. We first focus on their e

Generalized time delay, velocity, and absorption in dispersive and absorbing media

Autor: Guilhem Gallot

Publikováno v: Physical Review A. 99

The time delay and absorption of ultrashort electromagnetic pulses are defined from the local maximum of the wave's electric field and envelope. A time-domain framework is derived to obtain, in dispersive and absorbing linear media, the expressions o
