At the end of the year, we would like to express our deep gratitude for our collaboration with all editors, referees, and authors in 2021. Please take a look at our Christmas card. Since our virtual office is closed from 23 Dec to 2 Jan and a significant number of editors and referees pause their work over the Christmas days, we extended all journal review deadlines: deadlines expiring shortly before or over Christmas have been extended to the week after and deadlines expiring after Christmas or over New Year have been extended to after New Year’s Day. Season's greetings and a happy New Year. Please stay healthy.
