We can also observe from Figure 4 that the difference of the number of feedback bits between the proposed method and LF-OSDMA for M = 1 is constant, which represents the number of feedback bits of the full CSI from initially selected users.
A maximum likelihood tree was then built using RAxML v7 [ 73] with the LG + Gamma model of evolution, and this tree was then made ultrametric using the r8s software by constraining the root node and using the LF method and TN algorithm [ 79].
In this section, we compare the latency among the proposed method, LF-OSDMA, and the extended LF-OSDMA.
In this subsection, we compare the number of feedback bits among the proposed method, LF-OSDMA and the extended LF-OSDMA.
In this simulation, we also randomly selected the initially selected users who feed their full CSIs back, and S affects the amount of feedback, but is not dependent on the number of transmit antenna N t. Figure 6 CDF of the capacity on a per-user basis for the proposed method, LF-OSDMA, and the extended LF-OSDMA, N t = 4, SNR is 5 dB and the number of users is K = 50.
We used three different techniques to estimate divergence times from our matK gene tree: (1) a Bayesian relaxed clock model implemented in BEAST v1.4.8 [ 69], (2) a penalized likelihood (PL) method, and (3) the Langley-Fitch (LF) method.
Expression and purification of PA and LF is described in Methods S2.
For convenient comparison of GC and LF, P-values falling beyond the thresholds (see Methods) are also listed.
As example are reported, the December 1998 dataset with red dots, the partitioned population (HF and LF populations) for this dataset using Sinclair method71 (see Methods) with the dashed lines, and the theoretical distribution resulting from the combination of the HF and LF populations in the proportion 61% LF and 39% HF with the solid line.
In this study we evaluated the association between the LF axial transmission ultrasound method and fractures in a population-based sample of older women, using the standard DXA as the reference method.
