Especially rare are controlled experimental studies, which are the most unambiguous way to detect trade-offs.
The semiparametric approach provided unambiguous criteria to detect groups of genes, trajectories and probability of gene membership to groups.
We confirmed the ability of a semiparametric approach to provide unambiguous criteria to detect groups of genes, trajectories and probability of gene membership to the groups in two data sets.
Even though the Viking landers 27 years ago failed to detect unambiguous signs of microbial life, orbiting spacecraft have tantalized scientists with numerous images of what appear to be dry lake beds and sinuous channels, ancient coastlines and other landscapes that could have been shaped by running water.
The sequence of TPR subunits can diverge a great deal over time, limiting their consensus motifs and making it difficult to detect unambiguous duplication patterns for any of the proteins.
A greater amount (2 3 times) of ARTs was necessary to detect an unambiguous depth of colour on filter paper compared to that achieved on the TLC sheet.
Despite repeated attempts with four different antibodies, we were unable to detect an unambiguous, specific signal for GLUT-3 protein.
Finally, we illustrate how the new radiant mapping and meteoroid speed techniques can be combined for unambiguous meteor shower detection, and use these techniques to detect a previously unknown weak shower.
The very fine scale of the porosity (pore diameter ∼10 to 100 nm), coupled with severe difficulties in making unambiguous microstructural observations, may account for the failure to detect this feature previously.
Finding a lost golf course isn't as simple as you might think: the creators of early layouts did so little in the way of earthmoving that unambiguous evidence of their work can be difficult to detect, even for someone who knows where to look.
