We present the idea of forming SU groups according to their IDs, and the SU groups are assigned equal portion of spectrum for parallel sensing.
When we cerate more SU groups, then it implies that every SU has to sense less number of primary channels, thus saving energy during the parallel sensing phase.
In the considered example of two groups of SUs, all members of an odd ID SU group will sense channels 1,3,5,7,...,Nch−1 and the members of the other group will sense channels 2,4,6,8,...,Nch, as shown in Fig. 3.
This phenomenon may explain (at least in part) the relative increase in the prevalence of cardiovascular events in the SU group compared with BG groups even though a similar degree of reduction in the HbA1c level was achieved.
In the last su-group of five veterans, each veteran had at least one episode of exposure to an explosion that was associated with a behavioural change that RLR interpreted as possible but not definite episodes of AOC.
Differently from [17], where the BS infers its subordinate interest of SU in a multicast group from the MAC-layer management messages, in order to avoid periodic exchange of IGMP reports, we prefer to not include additional, mandatory functions in the BS.
Other limitations of this study are its homogenous Asian population, which may decrease external validity to other populations, and the use of SU in the control group.
There are two main limitations to this study: the use of SU in the control group, which limited the ability to separate the protective effect of insulin therapy on β-cell function, from the possible negative effect of SU.
A computer-assisted, least square method was used in random assignment to ensure that there was no baseline difference in gender, age, BMI, HbA1c, or duration of SU use between the two groups.
