We experimentally study a new regime for supercontinuum (SC) generation in the nanosecond pulsed regime using a microstructured optical fiber with two zero-dispersion wavelengths (ZDWs). Pumping at 1535 nm around the second ZDW yields a nearly flat SC over 1350–1700 nm. The interplay between the effects of modulation instability and stimulated Raman scattering are described through simple phase...

The RNA of hepatitis delta virus (HDV) 1682 nucleotides long, has been cloned from a human serum isolate. Comparison with the three complete published sequences shows that a region of the HDV genome, between positions 620 and 1350, which contains sequences involved in replication and possibly pathogenicity, is highly conserved.
