چکیده
We present the results of a feasibility study using shared, existing network-accessible infrastructure for repository replication. Our goal is not to “hijack” other sites’ storage, but to take advantage of protocols which have persisted through many generations and which are likely to be supported well into the future. We utilize the SMTP and NNTP protocols to replicate both the metadata and the content of a digital library, using OAI-PMH and the related Apache web server module, mod oai, to facilitate management of the replication process. We investigate how dissemination of repository contents can be piggybacked on top of existing email and Usenet traffic. Long-term persistence of the replicated repository may be achieved thanks to current policies and procedures which ensure that email messages and news posts are retrievable for evidentiary and other legal purposes for many years after the creation date. While the preservation issues of migration and emulation are not addressed with this approach, it does provide a simple method of refreshing content with various partners for smaller digital repositories that do not have the administrative resources for more sophisticated solutions.

In the context of confining gauge theories we study the flux tube generated by a pair of static sources belonging to higher rank representations of the gauge group. Using a simple geometric approach based on minimal surfaces describing the world-sheet of the underlying k-string, we infer logarithmic broadening of the flux tube as a function of source separation. It turns out that the coefficien...
