PCT levels have been shown to be correlated to several severity-of-illness scoring systems used in clinical practice, including APACHE II [ 45] and SAPS (simplified acute physiology score) II [ 39, 45] scores.
Therefore, recognizing a system as being nonlinear does not suffice, but the extent and severity of a system's inherent nonlinearity is the crucial characteristic in order to decide whether linear system analysis and controller synthesis methods are adequate.
The Mets, the Los Angeles Dodgers and the Seattle Mariners are among the handful of other teams that may question the severity of the system.
A certain process is defined to characterize the instantaneous severity of the system response with respect to a potential collision event.
Risk is a probabilistic index defined to reflect the severity of the system operation condition [27].
As such, our findings require further exploration in the context of a validated severity of illness system.
Regional differences were reported in the perceived severity of health system bottlenecks, and, thus, the perceived feasibility of KMC scale-up.
Marked differences were found in the perceived severity of health system bottlenecks between Asian and African countries, with the former reporting more significant or very major bottlenecks for KMC with respect to all the health system building blocks.
While we adjusted for numbers of organ failures, using administrative data prevented the use of a physiology-based severity of illness system that might provide greater detail regarding this observation.
