The world is a rather different place now than it was last November, when I wrote the last of these editorials. As we deal with the worldwide economic slowdown, social distancing and the other consequences of the Covid-19 pandemic, I am grateful to all members of the TSM community who continue to work under trying conditions to keep the journal’s business going.

社论

与去年11月，当我写完这些社论的最后一篇时，现在的世界已经大不相同了。当我们处理全球经济放缓，社会隔离以及Covid-19大流行带来的其他后果时，我感谢TSM社区的所有成员，他们在艰难的条件下继续努力，以保持期刊的业务发展。
