In addition to inclusion of non-Newtonian behaviour of blood in propagation, structural limitations of stenosis were accommodated by considering various appropriate models such as power law, Herschel Bulkley, Casson and Carreau models [20 33].
Although these experimental models help to elucidate the mechanism(s) of tau propagation, there are limitations from the perspective of developing novel tau-based therapies.
First, we consider the time course of signal propagation as a limitation on when auditory information (of any kind) can impact the responsiveness of a given brain region.
However, the offset in theoretical values is due to factors not taken into account in the model (such as radio conditions, propagation loss, interference, power limitations, etc).
Medium access (MAC) is an unresolved problem due to energy limitations, long propagation delays, low data rates, and difficulty of synchronization [4 8].
The problems of SRM's discontinuous structures and crack propagation also pose certain limitations to SRM numerical research (Sun et al. 2014b).
This paper starts by looking at the two-way relay channel (TWRC), where two terminals, for some reason, cannot directly communicate (e.g., due to propagation obstacles or power limitations) and are forced to exchange data via a relay.
Although GEO satellites have been a subject of substantial focus by the telecommunications industry, they still pose significant network design problems, such as long propagation delays, the limited bandwidth to be shared among many users, and limitation in power.
A general limitation of mathematically precise approaches to approximations, cf. also the propagation to chaos limit theorems in [30], is that the microscopic models are usually defined via the limit.
In practice, a precise hexagonal pattern cannot be generated, due to topographical limitations, local signal propagation conditions, and practical limitations on sitting antennas [12].
