As we greet the Year of Tiger, we are excited to see ISE2022 becoming closer and closer. For those who celebrated the Lunar New Year, we hope you have had a great time and is now as energetic and rigorous as the tiger. Our submission system was scheduled to close on 15 Feb (local time in Nanjing), but as we have received repetitive requests for late submission, we have decided to extend the deadline by another week. This is the last extension and we really could not postpone it any further because of the considerable time required for reviewing. If you have already submitted your abstract, please ignore this email. But if you still plan to submit one, we hope you could understand and catch the final deadline.
