Since skin can remain hyperreactive after wounding or postoperatively, 6 we selected a challenging model system to test this new shampoo formulation: the status after hair transplantation.
Therefore, we chose the status after hair transplant as a highly challenging model system to test this new shampoo.
However, while Scn1b null mice are interesting, their early death at postnatal day 19 and complex phenotype make them a challenging model system.
Thus, it is a challenging problem to study the synchronization among multiple chaotic systems with unknown parameters, which is the main motivation of this work.
Industrial S. cerevisiae strains provide a good model to study molecular adaptation to challenging environments.
With the establishment of Danio rerio, a member of rasborine clade A, as a model organism for vertebrate developmental genetics [ 30] the proportioned dwarfs and the developmentally truncated miniatures offer a challenging system of "natural mutants" to study the loss of characters and the evolution of morphological novelties comparatively at a genetic level.
Recurrence risk studies can be challenging in other dimensions, including inherent biases, generalizability of findings, inadequate study size, and inappropriate use of analytic models to study recurrence.
The glucose-insulin system is a challenging process to model due to the feedback mechanisms present, hence the implementation of a model-based approach to the system is an on-going and challenging research area.
It is very challenging to study the pathogenesis of human neurological disease, due to the complexity of the neuronal system and the difficulty of culturing neurons in vitro.
11 Neural models have not routinely been employed because the key neural migraine pain circuitry is much more challenging to study.
