Because of scheduled maintenance of the campus electricity, mail and WWW at "kb.ecei.tohoku.ac.jp" will be down on May 21 (Saturday) and 22 (Sunday) JST. Although this blog itself is not affected, the links and mail addresses at "kb.ecei.tohoku.ac.jp" will be unavailable during the weekend. Sorry for any inconvenience.
[Update on May 18: The dates were mistaken in the initial version of this post (which was online for a few minutes). They are now corrected.]
