I know that it is very hard to get admissions from top schools without a publication. Though I am currently working on my research, I am not sure if it will be published on time (before the application submission). I have some other  
internship experiences (around 3 months); however, I am not sure if it will help.  
 
Let me know if there is a case for top grad school admission w/o publication. I am currently thinking of applying to MIT/Stanford/UCB/CMU/Princeton/Harvard. If I end up not getting an admission, I would reapply after getting a M.S degree from my current school.
