However, in the simplest case, where the weights on trees are all the same and the distance between trees is the RF distance, finding the ML supertree is identical to optimizing Sum-RF (minimizing the total topological distance, using Robinson-Foulds scores, to the input trees), a criterion that is almost identical to Sum-FN.
For relatively small data sets with points arranged in ascending order, this is usually a simple matter of finding the biggest "cluster" of identical values and counting the number of occurrences.
Hoffman: The projects we take on here may seem superficially similar but they're never identical, so finding the unique elements of each opportunity forces the team to see projects from a fresh perspective.
Minimization of F is identical to finding the (locally) maximum a posteriori estimates of w, denoted w MP, which minimize E D using the back-propagation training algorithms [ 24].
By this assumption the solution to Equation 3 is identical to finding the maximum of the log of the product term in Equation 4 over the parameter space; that is the solution to Equation 3 is identical to This equation is similar to the maximum likelihood estimator in classical statistical theory, but weighted over the prior densities for the parameters in the model.
To confirm these findings, the identical flight experiment was performed again aboard STS-123 (Figures S2 and S3).
The finding of the identical mutation raised the suspicion of cross contamination between cell lines.
An additional important finding is the identical role played by nNOS in the three species studied (rat, mouse and human), suggesting that the function of the enzyme has been preserved throughout evolution.
Because the oxidative burst signal increased during the hypergravity phases of parabolic flights, we performed luminol kinetic measurements on the Short Arm Human Centrifuge (SAHC, DLR, Cologne) to verify this finding using the identical hardware (PMT clinostat, non-rotating).
These findings challenge the "identical fingerprints – same strain" dogma and have important implications for the investigation of disease dynamics, especially in high incidence regions such as Eastern Europe where the Beijing genotype is dominant and the population diversity (e.g. among MDR strains) is significantly reduced [unpublished results,14,33].
