  • We observe the distortion of the back scattered Stokes pulse and the complementary distortion of the transmitted pulse by the stimulated Brillouin scattering when a Q-switched Nd:YAG laser pulse injected into a single mode optical fiber. We determine the constant required energy for the SBS by comparing their temporal shapes.

  • The native forms of some proteins such as inhibitory serpins (serine protease inhibitors) and viral membrane fusion proteins are metastable, which is critical to their functions. To understand the mechanism of how native metastability regulates the inhibitory function of serpins, we characterized stabilizing mutations of $\alpha$$_1$-antitrypsin, a prototype serpin, in which Gly 117 was replaced by a series of larger hydrophobic residues.(omitted)

  • The Dublin Core element set has been developed over the past years as an open, consensus-building metadata from many user communities. Wider adoption in many countries made this metadata a major resource discovery standard on the internet. The version 1.1 of the Dublin Core element set was adopted as CEN Workshop Agreement 13874 in Europe, and also ratified under the auspices of the National Information Standards Organization in US as ANSI Standard Z39.85. This report summarizes the standardization activities that have taken place in the Dublin Core Metadata Initiative for the past years.
