Can you write a little more about why you’d like to hide the language codes? We added them to the URL intentionally for at least a couple of important reasons:
We want to reduce our use of cookies for non-authenticated users; storing the current locale was one of the few uses of cookies that made this necessary
Search engines will be much better able to fully index content when the locale code is included in the URL.
It might be possible to use URL rewriting to remove this, but I suspect you’d find yourself struggling with both of those issues!

If this is problematic enough to implement on the current version, then I will simply pass this information on to users. The curator of the journal wanted to have “clean” links, without the language code in them. That’s actually the whole purpose.
