Sentence examples for constraints may exist from inspiring English sources
Many other impeding constraints may exist that are as important as limited access to finance.
However, some constraints may exist in the short-term balancing of electricity supply and demand, that is, in the flexibility of the electricity supply system.
In such organisms, where breeding, collection, and/or budgetary constraints may exist, such a model-selection procedure is essential.
However, if a gene has either multiple functions or is expressed in multiple tissues, strong pleiotropic constraints may exist forcing selection to be sub-optimal in order to balance fitness requirements.
Limited gene duplication was detected among the autophagy genes in D. melanogaster and three mosquito species (Ae. aegypti, An. gambiae and Culex quinquefasciatus), supporting the interpretation that selective constraints may exist.
As has been shown with some systems, this could be partially attributed to differential selective pressures resulting from host cycling [ 16, 21, 22, 49], yet studies with mosquito-adapted WNV MP20 demonstrate that host-specific adaptations without significant fitness trade-offs in vertebrate hosts are attainable, suggesting other adaptive constraints may exist [ 24].
Thus, less constraint may exist on phase-specific evolution in the pilidiophorans than in animals whose larval stage preforms the adult.
To determine whether functional constraint may exist at the sites corresponding to the seven candidate mutations, we determined the orthologous major allele at each of the sites in chimpanzee, gorilla, orangutan, macaque, mouse and Fugu.
We hypothesized that this could be due to other, non-energetic constraints that may exist for natural sequences (e.g. Humphris and Kortemme 2007).
On the other hand, soft constraints may allow for unnecessary violations of the original constraints, i.e., the constraints may be violated even if a valid solution that does not violate any constraints exists.
Certain constraints may be needed.
