The U.S. has been putting some significant resources into this, greater amounts than we have, but I'm not sure they have had the kind of successes that we have had to date in terms of bringing together different partners from the medical research community, from industry, from research centres such as TRIUMF and others to work together to find those solutions. They're struggling in the U.S. right now. They're looking at other technologies. Some would be more expensive; some would be larger scale. We're not unhappy with where we are right now, frankly.
