I thought "yet" was to be used in negative sentences. So in a certain context, I'd have said: Haven't they arrived yet?" However, I've read "Have they arrive yet?"
Is it correct?

• [with negative ] as soon as the present or a specified or implied time : wait, don't go yet.
• from now into the future for a specified length of time : I hope to continue for some time yet.
