All abstracts are presented as posters. A select number of abstracts will be selected for a short oral presentation in addition to the poster display. The poster session, accompanied by a wine and cheese reception, will be Wednesday, May 19, 4:00-7:00 pm in the Sequoia room. Poster set up will be on Tuesday, May 18 from 8:00 am-4:00 pm.  Poster Boards are 4' x 4' and are double sided (usable area 46" x 46"). We strongly recommend that posters be 36" x 46" in either landscape or portrait mode. The 46" dimension is not an error — 46" will ensure that your entire poster fits within the metal frame of the poster board. Velcro tape should be used to hang your posters. Pins, thumb tacks or tape of any type are not permitted to be used on the poster boards. We will provide velcro tapes at the meeting.  Abstract numbers will be indicated on the poster boards. Posters should include the title of the abstract and the names and affiliations of the authors. All information should be readable from distances of four 4 feet (1.2 m) or more. Posters may be removed on Thursday, May 20 between noon and 1:30 pm.
