The high metabolic costs of burrowing, in terms of O2 consumption and CO2 production, are exacerbated by the obligate re-breathing of expired air while tunnelling, and may therefore require adaptive modifications in hemoglobin (Hb) function.
In many situations, invasion may be facilitated, or may even absolutely require, adaptive evolution to novel environments, similar in some respects but differing in others from the environments found at the site of origin.
This may require hybrid, adaptive protocols, where the network's behaviour adjusts depending on the circumstances.The ad hoc approach is also favoured by proponents of ultra-wideband (UWB) transmission.
Successful bacterial transfer across large phylogenetic distances may require rapid adaptive evolution in the new species.
A minimal justification of this statement is based on probabilities: i) the cumulative probability of accident or disease that may cause disabilities increases across the lifespan, and ii) disabilities that require adaptive technologies are generally not reversible.
Yet technological innovation has a bleak dialectic: advances in warfare usually require adaptive mechanisms purchased at tactical cost.
In general, the platen or any adaptive structure may require high-bandwidth dynamic control.
Thus, detecting "adaptive decay" may require more dramatic modifications to the environment.
When defining adaptive features one needs to establish firstly which protocol areas will or may require flexibility to allow for adaptation, i.e. the categories of adaptations.
Prevention of persistent Salmonella infection with recrudescent disease, as commonly found in HIV-infected Africans [7], is also an important goal of vaccination and this may require the development of a robust adaptive cellular response to NTS.
