The extent of variability and flexibility is thus reflected not only in the technologies employed, but also in how different reduction sequences were segmented and executed across the landscape, suggesting a link between technical knowledge, mobility patterns and landscape exploitation.
The characterization of the biological rhythms is usually based on (1) the periods related to the completion of one cycle, (2) the levels conferring to the rhythmic variation baseline, (3) the amplitudes depicting the extent of variability, and (4) the phases involving peaks and troughs corresponding to the respective time scale [ 5, 37].
The extent of genetic variability and Plasmodium's track record "makes you think, 'Whoa--these guys will be able to adapt pretty quickly to new drugs,'" Clark says.
First, we examined the genetic diversity and antigenic relationships of CHIKV sequences from its introduction into humans in 1952 to 2009 to assess the extent of geographical variability and existence of potential selective pressure.
There are more than 4 million SNPs in the human genome, 200,000 of which occur in coding regions, underlying the extent of genetic variability and its potential positive or negative effects on the host antimicrobial defense [13], [14].
In this study, we extended the analysis to full CHIKV structural and non-structural sequences and examined for the first time, the genetic diversity and antigenic relationships of CHIKV sequences from its introduction into humans in 1952 to 2009 to assess the extent of geographical variability and existence of potential selective pressure.
The work presented here aims at better characterizing the extent of HeT-A vandability andeterminingng if different HeT-A subfamilies could become more successful in a given stock.
In principle, simulation studies could be conducted to estimate the extent of exposure variability and contribution of various sources to the total exposure to optimize the exposure assessment [see, e.g., Whitaker et al. (2003) for an example from another field].
Accurately assessing the amount of genetic polymorphism within many species of ascidians will give an indication of the extent and variability of this high polymorphism phenomenon, and may give an indication of its cause and significance.
The extent and variability of the activity, the kinetic properties, and the implications of the tumour enzyme in paclitaxel metabolism are also analysed.
