Aargh, we worked so hard but in the end we felt that the paper was not ready to
be submitted. The deadline has been extended by a day, but I am not really sure
if we will be working on it tomorrow. In fact, I think I will work on my other
topic.

<p>

Also, I think I need to take a break and go hiking or something this weekend. We
will see. Usually, I go out to see fireworks on the American Independence Day
(July 4th), but this time I was in the lab working on the paper. Well, guess
next year it would be better.
