All submitted papers are double-blind reviewed by two referees and acceptance is decided upon the review by three referees in case of discordance between the two referees.

The first draft should be arranged as follows:

Title page (page 1) should include

(a) full title,

(b) names and affiliations of all authors,

(c) mailing and email addresses and phone number(s) of the lead author,

(d) address to which offprint should be sent (if not that of the lead author),

(e) short title of less than 50 characters.

To facilitate blind review, all indications of authorship must be limited to this page. Other pages must only show the short titles plus page numbers in the upper right corner.
