Static and Dynamical Properties of Dispersive Optical Bistability in Semiconductor Lasers

Absfnzst-Static and dynamic properties of dispersive optical bistability (OB) in semiconductor lasers biased from below to above threshold has been investigated both theoretically and experimentally. The OB result is found to be varied continuously from below to above threshold; Although conventionally the OB switch-off time in dispersive semiconductor laser ampliers is limited by the effective...

Critical Exponents in Cytosolic Diffusion

The interior of a cell is very crowded (up to 35% protein by weight), with significant consequences for diffusive transport. The possible trajectories of a given tracer particle are constrained by the labyrinth of obstacles. For a static obstacle configuration, a percolation transition takes place at a certain critical obstacle density, so that above this density no long-range transport is poss...

ON QUASILINEAR ELLIPTIC SYSTEMS INVOLVING MULTIPLE CRITICAL EXPONENTS

In this paper, we consider the existence of a non-trivial weaksolution to a quasilinear elliptic system involving critical Hardyexponents. The main issue of the paper is to understand thebehavior of these Palais-Smale sequences. Indeed, the principaldifficulty here is that there is an asymptotic competition betweenthe energy functional carried by the critical nonlinearities. Thenby the variatio...
