Conception and development of an adaptive optics testbed for free-space optical communication [PDF]
, 2009 Optical free space communications are an efficient approach to transmit high data-rates with small antennas and low power consumption over large distances. Possible scenarios are links between satellites, up- and down-links from and to ground stations as

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

High speed train communications systems using free space optics [PDF]
, 2010 In this work, we propose a broad-band free space optical (FSO) wireless communications system for high-speed trains. The system consists of optical transceivers positioned outside the train and along the railway track.
