Mr Werning asks the same question, but in the forward-looking, macroeconomic setting provided by Ramsey.Mr Werning and his co-authors have so far derived at least two theoretical results of note.
This intriguing and clinically highly relevant concept, however, has so far been derived from small case-control studies and patient series.
Despite the early recognition of miRs as translational regulators and intense interest in studying this phenomenon, it has so far not been possible to derive a consensus model for the underlying molecular mechanism(s).
However, an outstanding incongruence between the palaeobotanical finds and molecular systematics of legumes is that the earliest fossil record of the tribe Cercideae as sister to all other lineages in the molecular phylogenetic trees of Leguminosae [ 9- 14, 20- 24] has so far occurred later than that of some derived tribes bearing compound leaves such as Sophoreae Spreng.
However, its performance indices have not been derived, and thus the gain determination has so far been conducted empirically.
Most of the data underscoring the significance of VASP for preserving vascular integrity have so far been derived from in vitro studies which in addition were mainly conducted in microvascular endothelial cell lines from myocardium, lung or skin under physiological conditions [15], [16], [19], [28].
While conventional wisdom proposes that hand hygiene [8], and perhaps surgical masks [26], could be effective measures to reduce household transmission of influenza, all available data have so far been derived from at best observational settings and mostly based on anecdotal evidence rather than controlled trials [7], [8], [27].
All approaches to optimal experiment design for control have so far focused on deriving an input signal (or input signal spectrum) that minimizes some control-oriented measure of plant/model mismatch between the nominal closed-loop system and the actual closed-loop system, typically under a constraint on the total input power.
