During fiber transmission
-
Optical coherent transmission links utilize a fourdimensional (4d) signal space. We review the search for good modulation formats in 4d, as well the properties of these formats under the (subset of all possible) 4d rotations that occur during fiber transmission.

The theory of neurohumoral transmission received direct experimental validation nearly a century ago (see von Euler , 1981 ), and extensive investigation during the ensuing years led to its general acceptance. Nerves transmit information across most synapses and neuroeffector junctions by means of specific chemical agents known as neurohumoral transmitters or, more simply, neurotransmitters.
