Generation and characterisation of 40 GHz picosecond optical pulses generated using an EAM [PDF]
, 2006 The authors describe the generation of short (< 4 ps) optical pulses at a repetition rate of 40 GHz using an InP electro-absorption modulator. The technique of frequency resolved optical gating (FROG) is subsequently used to accurately characterize the ...

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 ...
