Dispersion-managed solitons in periodically dispersion compensated fibre transmission systems allow for large duty cycle time-division multiplexed channels.

Transmission of 25 and 50 equally 100-GHz and 50-GHz spaced 10-Gb/s (OC-192) channels on the ITU grids is demonstrated over eight and four 83.8-km long spans, respectively, of DSF with the zero-dis

4×40 Gbit/s wavelength division multiplexed, dispersion-managed transmission over transoceanic distances with a record spectral efficiency of 0.27 (bit/s)/Hz has been achieved using simultaneous in

Cyclotron resonance at microwave frequencies is used to measure the band mass (mb) of the two-dimensional holes (2DHs) in carbon- doped (100) GaAs/AlxGa1-xAs heterostructures.

The 3x+1 function T(x) = (3x+1) over 2 if x is odd and x over 2 if x is even. Let pi sub a (x) count the number of n with |n| = x whic eventually reach a under iteration by T.

We have directly measured, under operating conditions, the distributions of carrier densities and temperatures in a gain-clamped semiconductor optical amplifier designed for operation at 1.55 mum.

We introduce a new topological descriptor of a network called the density decomposition which is a partition of the nodes of a network into regions of uniform density.

The negatively charged exciton (X(-)) is observed to strongly couple with the microcavity (MC)-confined photons in a GaAs quantum well containing a two-dimensional electron gas with 0 n(e) 3 x 10

Since the deduction of a discontinuity in the density functional exchange-correlation potential v sub (xc) across the energy gap [1,2], Godby et al.

The field-effect mobility in crystalline organic FETs is known to be an order of magnitude larger than the mobility observed in thin-film OFETs.
