According to stochastic process theory, if the input of a linear time-invariable system is a stationary random process, then the output of the system is also a stationary random process [76].
Maximum likelihood analyses of these alignments were performed in PHYML with 1000 bootstrap resamplings, the JTT substitution model, a fixed proportion of invariable sites, one category of substitution rate, and the BIONJ input tree.
By accurately encoding the naturalistic contrast input into the rate of change of voltage responses (and so generating an invariable bandwidth for NS), the locust photoreceptors provide robust neural representations of the natural environment already at the first stage of neural information processing.
The input trees were calculated using PHYML 3.0 [69] with a GTR substitution model, proportion of invariable sites and among site rate parameters estimated from the data.
ML analyses were performed using PhyML software [62] with an input tree generated by BIONJ with general time-reversible models [63] of nucleotide substitution incorporating invariable sites and a discrete gamma distribution (eight categories) (GTR+I+Γmodel).
The results showed that the control system can work well and meets technical requirements of engineering application using PID control; in PID coefficients under the condition of invariable, the system working frequency not only limit by the natural frequency of hydraulic pump, but also with the input displacement values have close relationship.
PhyML was performed using an input tree generated by BIONJ with the general time-reversible (GTR) model [19] of nucleotide substitution incorporating invariable sites and a discrete gamma distribution (eight categories) (GTR + I + Γ).
Adverbs, prepositions, conjunctions, and interjections are invariable.
"Like Obama!" is the invariable response.
He went on to describe his "invariable" working method.
Consuelo is a Spanish abstract noun, masculine, invariable.
