I wanted to create such a model, but it misconceived.

I want one like that. The different headers because the second has a line that splits the text.

In the first one besides the logo, the line, the text box in three more lines below that I could not put in the first heading.

The alignment of the title and authors always change.

I would like to insert the addresses after the abstract, but " maketitle" does not allow.
