What's more, these models tend to be rather rigid, built to handle a single set of questions.
One might expect that a dynamical system whose attractors have large frozen cores and very small 'twinkling islands' is rather rigid and therefore unlikely to be adaptable to the external environment and also unlikely to be evolvable.
While it may sound rather rigid and time-consuming to formulate a sound marketing strategy first, it is akin to penning a script for a play or movie - it provides a supporting structure that precisely choreographs where you want programs to go.
Because the peptideOSM is structurally stable and structurally rather rigid with a good affinity to the ADIPOR1 receptor and correctly located to mimic the adiponectin binding, at the moment it represents, at best of our knowledge, the only good model of adiponectin agonist in vitro.
Generally speaking, plant behaviour is still assumed to be rather rigid, stereotyped and inflexible, and even when plants demonstrate cognitive competences such as the ability to learn, for example, their learning capacity is widely considered to be fully pre-programmed.
This is very likely the case for most of the proteins in this data set because they all have solved tertiary structures and so are biased to having rather rigid structures.
It is worthwhile to mention that in the case of rather rigid polymer brushes or polyelectrolyte chains an isotropic to nematic phase transition occurs upon increasing the volume fraction.
All of these poems, foregrounding their own eccentricity, choose rather rigid homemade forms and then stick to them.
I suspect that most people think of etymologists as a rather rigid lot, insisting on universal obeisance to some outmoded concept of proper English.
