The emergences of vertebrates and endotherms indicate the two great leaps in metazoan evolution, and thus metazoan evolution was divided into three consecutive phases named the Non-ver (invertebrate) phase, the Ver-eco (vertebrate ectotherm) phase and the Ver-endo (vertebrate endotherm) phase.
To understand the inclination mechanism, the whole process of the inclination evolution is divided into three stages according to the inclination angle growth rate.
In this paper, the thunderstorm evolution is divided into three stages as growing, mature and dissipating stages according to its development.
The measurements show that the sidebranching evolution is divided into two regimes: an initial linear regime and a subsequent non-linear coarsening regime.
The process of channel evolution is divided into four stages, and we have concluded that the causes of channel change include six factors from two categories: natural factors that include geological conditions, hydrological conditions, and the process of bedrock erosion; and human factors that include gravel mining, lateral structures, and levees.
The population size was set to 1000 and the modeling process was set to 5 million evolution steps divided into ten stages.
As a first step to understanding the dynamics of GS pathway evolution, we divided the 52 to-date known AtGS genes into three groups: first, genes with a retained At-α ohnolog copy (table 1).
To further probe the interaction impact of promoter methylation and miRNA regulations on mammalian protein evolution, we divided the human protein-coding genes into five groups of similar size, according to the magnitudes of dN or dN/ dS, and calculated the median values of promoter mCG density and NmiR for each group of genes.
On the other hand, orthogonal frequency division multiplexing (OFDM) is one of the dominating transmission techniques in many broadband wireless systems [4], e.g., IEEE 802.16 (WiMax), EV-DO Revision C, and the long-term evolution, which divides the broadband wireless channel into a set of orthogonal narrowband subcarriers and hence eliminates the inter-symbol interference.
