The downhill transport of atoms on a sloping surface dominates at normal incidence, which suppresses the evolution of surface irregularities to form a rough surface.
Strong negative clonal selection against deleterious housekeeper mutations suppressed the evolution of a mutator phenotype (Fig. S3B).
Previous analyses of rapid evolution of cooperation that assume fixed population sizes often focused on identifying whether rapid evolution enhances or suppresses the evolution of cooperation, while potential density dependent-effects are usually ignored [ 15- 18].
The strength of selection for new driver mutations determined whether a mutator phenotype would evolve; very strong or very weak selection for driver mutations suppressed the evolution of a mutator phenotype (Fig. S3A).
Within the model, cancers evolve with a mutator phenotype when driver mutations bestow only moderate increases in fitness: very strong or weak selection for driver mutations suppresses the evolution of a mutator phenotype.
Cancers were more likely to have evolved a mutator phenotype when selection for additional driver mutations was moderate s d ∼0.01; strong selection for additional driver mutations suppressed the evolution of a mutator phenotype (Fig. 4A).
Although hydride formation appears to suppress the hydrogen evolution reaction, nevertheless the hydrogen-evolution activity remains relatively high.
Furthermore, the MnO2 nanowire layer coated on the graphene layer could significantly suppress the oxygen evolution reaction, broadening the potential window of water stability.
Cell design and configuration have also been considered but the basic requirement to engineer a selective catalyst able to suppress the hydrogen evolution and the elucidation of the mechanism of borohydride ion oxidation, remain.
