The scaling laws of the throughput and/or delay of coexisting primary and secondary ad hoc networks under various protocol settings have been investigated in [29,31-33].
Spectrum utilization may be very low for some periods of time, and in some specific locations; therefore, some MSs may form a secondary ad hoc network and communicate directly with each other.
Primary AD is much more common than secondary AD.
These models could also be useful for the design of future primary and secondary AD prevention trials in pre-symptomatic individuals.
Yarkony et al. described three cases of seizures secondary to AD that are compatible with HE [8, 9].
In order to explore the differences between CI, SVI, and the heart rate (HR) detected by each monitor, a secondary analysis ad hoc was performed.
As the hyperphosphorylation of Tau is believed to be relatively specific to AD, the observation of elevated CSF pTau is thought to be a more specific early indicator of neurodegeneration secondary to AD.
This may be partly explained by the possibility that the association between ACE1 variation and ACE levels is, in fact, relatively weak or that there are overriding changes to the normal regulation of ACE expression and activity secondary to AD- or Aβ-related pathology.
However, as illustrated by one of our autopsy-proven patients, a positive amyloid PET scan does not exclude the presence of CBD or another meaningful co-pathology, although in this case CBD was considered secondary to AD in driving the clinical syndrome of CBS.
