Nishiyama visited a collaborator Alvaro Kohen-Luque at Oslo University together with another collaborator Walter de Back (@ UT Dresden).
This was the fist time for me to visit North Europe, so everything exited me. It was not so colder than I thought, and it was so surprised that it was much colder in Bielefeld of Germany where I subsequently visited.
We mostly completed making the outline of our collaborative manuscript to submit. During weekend, we enjoyed short trip to mountain area, seaside,
Opera house and something, and home party.
Oslo is one of the towns I want to visit again.
