These advances are a testament to the advent of new technologies that allow for the direct manipulation of a model organism's genetics [ 24- 26]; they also demonstrate the power of comparative genomic techniques in improving our understanding of animal genetics as a whole.
Three of these types, i.e. when the attack occurs at the level of measurement, decoding and feedback, may involve direct manipulation of a person's neural computation.
The mechanism of influence might be a function of an antecedent to channel behavior, a consequence following the behavior, a set of words about the behavior, or direct manipulation of physiology.
We found that the in-plane orientation of a single nanomembrane can be controlled about a single point of rotation, by harnessing the deleterious scattering force that otherwise precludes direct manipulation of membranes without an attached bead.
Use of chromatin-modifying agents showed that direct manipulation of chromatin dynamics had a marked effect on the extent of stochastic gene expression.
As a result, methods within each class would facilitate the direct manipulation of biological data without the need for tedious file parsing.
When using direct manipulation of grazing, if the IAP has a different phenology than some of the native species present, then grazing can be applied at a time when the IAP is most susceptible, thereby manipulating competition among species within the community.
In 15 cases of the EIN group, close reduction of the fracture site could not be done, so an additional small incision was made above the fracture site for direct manipulation of the main fragments before the nail was introduced into the lateral fragment and the fracture was compressed.
