The horizontal lines represent abstraction barriers that isolate different levels of the system.
Reforming the consumer model of health care will require action at all levels of the system, including the way we train doctors.
Multiple problems at various levels of the system – recession, phone hacking, EU crisis, the riots, etc – are combined in a single, prolonged convulsion.
The steady-state levels of the system components were numerically solved, and thus, did not rely on the use of power-law formalism and an analytic solution93.
Vertical shafts and solution chimneys have no direct relation to the conduit system, especially not to the upper dry levels of the system.
By elevating the background expression levels of the system, this leakiness reduces the dynamic range of the system and limits it usability for control of downstream gene expression.
"What I am pointing to is the evidence that is provided by the government that makes it very clear that this type of permissive environment was condoned at all levels of the system".
When the top levels of the system decide to intervene in another state's affairs, it is therefore an action that has originated from the will of the people at the bottom-most levels".
The approach developed can be used for evaluating the contributions of lower hierarchical levels to the functioning of the higher hierarchical levels of the system.
Third, leaders must embrace the inconvenient truth that attempts to directly control agents at lower levels of the system often create counterintuitive outcomes at higher levels, such as the stagnation of a strategy or the collapse of an ecosystem.
In contrast to the small discrete perturbation in LSA, we perturbed E3 by continuously varying βTE3 or KTE3 such that E3 was upregulated initially and downregulated subsequently, and measured the steady-state levels of the system components.
