The intron sequences in genes are known to constrain codon usage both near and away from the intron locations (Chamary and Hurst 2005; Parmley and Hurst 2007; Warnecke and Hurst 2007).
Even so, battery longevity is arguably more of a pressing issue, given that the power demands for such a lightweight wearable are constrained by usage limitations.
I can't find out whether Twitter had reached out to IFTTT in the past about this, since I cannot get a statement from either company, but let's get one thing straight, this move has nothing to do with Twitter's new API changes, which I have felt strongly about, when it comes to constraining its usage.
"The one thing we are going to do as a result of all the feedback [ie criticism via Twitter etc] is look at the add-on packages because some people are saying… you're just constraining my usage — so we're going to look at whether we should build some bigger add-on packages," said Dunn.
But he also points out that the making of nominal essences is constrained both by usage (where words standing for ideas that are already in use) and by the fact that substance words are supposed to copy the properties of the substances they refer to.
Could the functional and evolutionary roles of certain repeats correspond to their particular characters, such as position bias, GC content constrains and codon usage?
Domestic coal usage is constrained and made more costly by an inadequate rail network.
Our principal finding that genomic word usage tightly constrains the spectrum of compositional variability between proteomes has further implications.
This Figure also contains a reference line (GCref) showing the expected position of genes whose codon usage is constrained solely by the nucleotide composition at the third codon position [ 20].
With this constraint and the RDG per unit BW from (8), we can predict the forward and backward BW usage and thus, constrain the possible BW usage of the next coded MB.
