Phylogenomic fingerprinting of tempo and functions of horizontal gene transfer within ochrophytes.

Author(s): Dorrell RG, Villain A, Perez-Lamarque B, Audren de Kerdrel G, McCallum G, Watson AK, Ait-Mohamed O, Alberti A, Corre E, Frischkorn KR, Piere...

Horizontal gene transfer (HGT) is an important source of novelty in eukaryotic genomes. This is particularly true for the ochrophytes, a diverse and important group of algae. Previous studies have ...

Abstract

We report experimental confirmation of the universal emergence of the Peregrine soliton predicted to occur during pulse propagation in the semiclassical limit of the focusing nonlinear Schrödinger equation. Using an optical fiber based system, measurements of temporal focusing of high power pulses reveal both intensity and phase signatures of the Peregrine soliton during the initial nonlinear evolution stage. Experimental and numerical results are in very good agreement, and show that the universal mechanism that yields the Peregrine soliton structure is highly robust and can be observed over a broad range of parameters.
