Field-trial of an all-optical PSK regenerator/multicaster in a 40 Gbit/s, 38 channel DWDM transmission experiment [PDF]
The performance of future ultra-long haul communication systems exploiting phase-encoded signals is likely to be compromised by noise generated during signal transmission.

Scattering amplitude in the Aharonov-Bohm gauge field [PDF]
A general expression for the scattering amplitude of nonrelativistic spinless particles in the Aharonov-Bohm gauge potential is obtained within the time independent formalism. The result is valid also in the backward and forward directions as well as for any choice of the boundary conditions on the wave function at the flux tube position.

Interaction of excitation and inhibition in processing of pure tone and amplitude-modulated stimuli in the medial superior olive of the mustached bat [PDF]
1. In mammals with good low-frequency hearing, the medial superior olive (MSO) processes interaural time or phase differences that are important cues for sound localization.

Large amplitude motion with a stochastic mean-field approach
In the stochastic mean-field approach, an ensemble of initial conditions is considered to incorporate correlations beyond the mean-field. Then each starting point is propagated separately using the Time-Dependent Hartree-Fock equation of motion.

A Field Investigation of the Permeability Dependence of Seismic Amplitudes
The direct determination of permeability from seismic data is a greatly desired but still unattained goal. There has been significant recent progress due to the work of Pride and Berryman (2003a, 2003b) and Pride et al (2004). They have developed theoretical relationships for seismic attenuation resulting from wave induced fluid flow.

THRESHOLD AMPLITUDES IN FIELD THEORIES AND INTEGRABLE SYSTEMS [PDF]
We discuss the threshold tree amplitudes in different nonintegrable quantum field theories in the framework of integrability. The amplitudes are related to some Baker functions defined on the auxiliary spectral curves and the nullification phenomena are shown to allow a topological interpretation.

Bootstrap and amplitudes: a hike in the landscape of quantum field theory [PDF]
Abstract This article is an introduction to two research programs that are currently very active, the conformal bootstrap and scattering amplitudes. Rather than attempting full surveys, the emphasis is on common ideas and methods shared by these two seemingly very different programs.

In the present study, a schematic has been proposed for generating terahertz (THz) radiation by beating of two dark hollow (DH) laser beams in plasma when a DC electric field is applied with a perpendicular direction.
