Hi Diego We will use the two-column format for the time being. You can download your source file after logging in with your username/password (let me know if you have any issues). I had the done the LaTeX layout for the other files--let me know if you want the .tex file if you want to do the conversion. Or else, I can get it done for you later. Actually, the current (two column) style required is only tentative--if we are ok with this, we can use it, or else if there are any LaTeX experts amongst us, they can develop an alternative layout and look. satish On Sun, Mar 11, 2012 at 9:01 AM, Diego Saravia <dsa@xxxxxxxxxxx> wrote: > do you need the article in two columns? > > latex style is available to test it? > > i do not remember wich file did I submit, is there a place to download it?
