The font in mathematical papers of Elsevier is elegant, as the figure below shows. I'd like to know the name of this font, that contains paconte and the command to call it.

For those who have access to a link to the PDF article is this.
I suspect that this font is protected by copyright and therefore there is a free package it. If this is the case then I would like a font in a free package available.
Is that possible?
Document Properties->Fontstab. It will show you the fonts used in the documentt1-gul-....are the ones that you are after. @JohnBaez Welcome to TeX.SX even if you were just ranting by :) – percusse Feb 27 '12 at 19:40In light of this, I believe this question should be re-opened, as the current answers may be outdated and future people finding this question could benefit from the knowledge of Charis SIL being available as an alternative.
