He has often been elusive, using false names, outdated addresses and stolen identification, including a dead woman's Social Security number.
Although candidate gene approaches based on comparable phenotypes in mice and humans have been utilized for this trait, the causative gene has remained elusive using this method.
Thus, for all but the most recently emerged and clonal species, fine-scale phylogenetic reconstruction has been elusive using common genetic markers.
For example, it can facilitate more effective integration of behavioral treatments with medications, a goal that so far has proven elusive using purely clinical approaches (Combine Study Research Group 2006).
However, achiral ammonium 265 is also reactive to aldehyde 263 furnishing racemic products, perhaps explaining why very high enantioselectivities are still elusive using this approach.
In addition, measuring the functioning of brain systems involved in behavior change in a given treatment, especially when combined with genetic biomarkers, may be used to identify patients who are likely to respond to that treatment, another goal that has been elusive using purely clinical approaches (Project MATCH Research Group 1997).
Although until recently, the presence of H3K56ac in mammals had remained elusive, using both mass spectrometry and antibodies in western blot analysis, three independent groups have now detected H3K56ac in human cell lines (Das et al, 2009; Xie et al, 2009; Yuan et al, 2009).
Lau and his colleagues found the elusive dust using NASA's airborne Stratospheric Observatory for Infrared Astronomy, which consists of a reflecting telescope aboard a modified Boeing 747 jumbo jet.
Civil society has always been a rather elusive concept, used and defined in many different ways.
Polaroids also sometimes led to happy accidents: unexpectedly artful blurs of the subjects; flares or highlights; the kind of painterly images that are often elusive when using more exacting film.
