We report the transmission of a record 6 Tbit/s capacity over 6120 km distance, involving channels modulated at 42.7-Gb/s bit-rate with differential phase-shift keying (DPSK).

We report the transmission of twenty 10-Gb/s channels with 100-GHz spacing over four 80-km spans of dispersion-shifted fiber in the lower wavelength region of L-band.

We demonstrate 845-km WDM transmission of eight 100-GHz-spaced 603-Gb/s superchannels in each core of a 76.8-km 7-core fiber placed in a recirculating loop.

We report transmission of twenty 10 Gb/s channels with 100 GHz spacing over four 80 km spans of dispersion shifted fiber in the lower wavelength region of the L-band.

We demonstrate 2688-km multi-span transmission using wavelength-division multiplexing (WDM) of ten 50-GHz spaced 128-Gb/s PDM-QPSK signals, space-division multiplexed (SDM) in a low-crosstalk 76.8-

Mobile network technologies require some degree of tracking of user location, specifically user equipment tracking, as part of their fundamental mechanism of working.

A family of microsystem chips, the UNIX(TM) Microsystem, has been developed at AT&T using top-down hierarchical design methodology and the 1.5 um CMOS technology.

Recently there has been considerable interest in the magnetic behavior of high nuclearity transition metal clusters since they represent ideal models for the transition of molecular units to small
