      <p>The workshop would not have been possible without the support of many people. First of all, we
would like to thank the program and organization staff, the members of the Technical Program
Committees and external reviewers for their excellent and tireless work. We sincerely wish that all
attendees benefited scientifically from the workshop and wish them every success in their research. It
is the humble wish of the workshop organizers that the professional dialogue among the researchers,
scientists, engineers and doctors continues beyond the event and that the friendships and collaborations
forged will linger and prosper for many years to come.</p>
