1. THE PHENOMENON Our work on adding the “missing user” to the telecommunication (telecom) policy discourse reaches back to the early 1990s.(1) Much like today, policy debates at the time raged over issues such as the upgrading of telecom networks and the need for new services, the (re)definition of universal service, the emergence of “information age” inequalities (e.g., the rural-urban divide...

This report shows the technical realisation of the 7 Telecom I+D in Barcelona. Telecom I+D is the main Spanish conference on telecommunications. This year, the Telecom I+D conference took place simultaneously in the Telecommunications Engineering Schools of six Spanish cities: Madrid, Barcelona, Valencia, Bilbao, Sevilla and Pamplona. Tutorials and presentations were given from Madrid and Barce...

We define an inversion statistic on standard Young tableaux. We prove that this statistic has the same distribution over SY T (λ) as the major index statistic by exhibiting a bijection on SY T (λ) in the spirit of the Foata map on permutations.

We utilize cross-phase modulation to observe all-optical switching in microring resonators fabricated with hydrogenated amorphous silicon (a-Si:H). Using 2.7-ps pulses from a mode-locked fiber laser in the telecom C-band, we observe optical switching of a cw telecom-band probe with full-width at half-maximum switching times of 14.8 ps, using approximately 720 fJ of energy deposited in the micro...
