Even though the exact mechanism for the results was not well known, some concerns may account for it.
In conclusion, if K 1 commutes with A ( t ) for all t ∈ R, Remark 3.12 applies with H 1 = − 2 K 1 and H 2 = − K 2. This section gathers, for reference purposes, a few simple facts - possibly well known - concerning time-dependent matrices.
The paper discusses four well known problems concerning polymeric glasses and argues that since glassification occurs in many systems, the simplest system, that of polymers, should be investigated first.
An intuitive solution-doubling argument establishes well known results concerning the worst-case performance of spanning tree-based heuristics for the Steiner network problem and the traveling salesman problem.
It is shown that the role of the environment is irrelevant for such kind of P systems, in contrast with the well known results concerning to its relevance when membrane separation is used instead of membrane division.
These well known data concerning the impact of avoparcin and Lactobacillus sp on WG in animals and humans may explain the results found with vancomycin in the present study.
Having been generated from a retrospective analysis, our results should be evaluated with caution because of the well known biases concerned with this methodology.
Unit of analysis is a well known statistical concern when individuals are recruited and followed in clusters and the problem may be mentioned in the section on statistical analysis e.g. "If an intervention is targeted at changing a workplace, rather than individuals, then each workplace might count as just one unit" [ 11].
The Union of Concerned Scientists, well known for its concern over global warming, signed on, too — it actually helped to write the standards.
It is well known that the concerns and priorities of patients differ from those of surgeons and that surgeons are more satisfied than patients with the results of TKR and THR (total hip replacement) (Lieberman et al. 1996, Bullens et al. 2001).
[M, 52, thicker, SSM, 42w] Patients' concerns about 'wasting their GP's time' are well known, but this concern appeared to be exacerbated by the small size of the skin changes and the lack of pain or other features that could signify more serious conditions.
