Isoetes differs from both Selaginella and Lycopodium in the occurrence of secondary growth in the stem and the possession of a definite root-producing meristem.
Of the 554 patients having an MRI scan, 37.8 % were found to have evidence of definite nerve root compression and 15.9 % of possible nerve root compression, on the relevant side.
Remark 1 A stronger inequality than (2.4) was given in Lin [[5], Lemma 2.2]: Let A > 0 and any Hermitian B. Then A ♯ ( B A − 1 B ) ≥ B. Proof of Theorem 1 Let λ j, j = 1, …, n, be the eigenvalues of B − 1 2 C B − 1 2, where B 1 2 means the unique positive definite square root of B. Then we have | 1 + i λ j | ≤ | 1 + λ j | ≤ x 2 + y 2 | 1 x + i λ j y |. (2.2).
On the other hand, outgroups (used to place the root of the tree) are a definite source of imbalance.
In the absence of definite proof of dorsal root ganglia involvement or other gold standard, we provisionally classified the SNN patients in the study population according to two levels of certitude for the diagnosis of SNN.
Among those with a clinical diagnosis of sciatica, 60.7 % had definite or possible nerve root compression on MRI compared to 32.4%% of those diagnosed with referred leg pain.
The assessor provided a clinical report indicating the presence/absence of definite or possible nerve root compression by lumbar spinal level (3 lower lumbar levels) and side (right/left) and the reason(s) for it if present (e.g. disc prolapse, stenotic features, etc).
Not definitive, just definite.
With an upper paleontological limit of about 125 million years before present, MYBP, for the divergence between marsupial and placental mammals [28] the inclusion of Sminthopsis constitutes a definite advantage in determining the root of the tree of placental mammals.
After a well written review of previous work, he urges an accurate, detailed impression of labour conditions online in respect to specific sectors and companies, rooted in a definite understanding of exploitation.
