As hobiwan pointed out, in the UR 14 you can remove 4 from r4c9 and r6c3 (or 1 from r4c3 and r6c9 resp.).
Additionally in the 2 rows one of 1 and 4 must be outside the UR in the two rows (as boxes and columns) to destroy the deadly pattern. There are only the three 1-candiates in r4c2, r4c8 and r6c8. r4c9 sees all of them, thus 1 can be eliminated there too.
