This paper presents single channel, 200 Gb/s, 20-bit DPSK packets generated by an optical arbitrary waveform generation based optical transmitter with chromatic dispersion precompensation, and their transmission through 100 km of single-mode-fiber and recovery. ©2010 Optical Society of America OCIS codes: (320.5540) Pulse Shaping; (060.1660) Coherent Communications; (320.7100) Ultrafast Measure...

40-bit OOK, 80-bit QPSK and 120-bit 16-QAM packets are generated with spectral efficiencies of 1, 2 and 3 b/s/Hz, exploiting concepts from OAWG. Results demonstrate potential for a Tb/s OAWG based transmitter using GHz electronics. ©2009 Optical Society of America OCIS codes: (320.5540) Pulse Shaping; (060.1660) Coherent Communications; (320.7100) Ultrafast Measurements.

This article argues that a mutual shaping lens enables a more encompassing account of the joint processes of technological and social change in new media than the diffusion of innovations and social shaping of technology perspectives. Drawing from recent work in sociology and history of technology, organization studies, social informatics, and computer-supported cooperative work, this article s...

Religiosity acts as an important marker of personal self-identification and identification social processes. The paradigm in relation to religion is changing: the secularism state ideological pluralism contributes expanded understanding not only a spiritual tradition, but also institution socialization. This article examines dynamics religiosity Kazakhstan, focusing on impact traditional new fo...

Technology made modernity possible. It has been the engine of modernity, shaping it and propelling it forward. The Renaissance was made possible by major fourteenthand fifteenth-century inventions like the mechanical clock, the full-rigged ship, fixed-viewpoint perspective, global maps, and the printing press. The emergence of industrial society in the eighteenth century was the result of an in...

Nina Wedell is a Professor of Evolutionary Biology at the University of Exeter based at the Cornwall Campus, UK. She studies the evolutionary ecology of sex, in particular the role of selfi sh genetic elements in sexual selection and sexual confl ict. Her current research explores the potency of selfi sh genes in shaping the reproductive biology, mating system and even the sex of their host, an...
