Moore understands the expansion of 'commodity frontiers' as a socio-ecological process, defining a frontier as a "zone beyond which further expansion is possible" [23].
In keeping with published methodology, for each year we identify the highest recorded life expectancy, that is, the leader. 1 6 7 These point estimates define a 'maximum frontier'.
To address these challenges policymakers must define a health policy frontier that identifies primary interventions according to current health priorities.
To address these challenges, policymakers must define a health policy frontier that identifies the primary interventions according to current health priorities.
In the first article of this issue, Maria Victoria Anauati, Sebastian Galiani, and Federico Weinschelbaum define a health policy frontier, which is understood as the primary interventions according to the current health priorities of Latin America.
Similarly, we identify the country with the lowest recorded mortality rates in a given year (leader), which defines a 'minimum frontier,' and we compute the comparators' average observed mortality rates per age group.
In case that the traffic loads for both kinds of traffic are known imperfectly, we should define a robust Bayesian threshold frontier by means of extending the previous integrals to include simultaneously the uncertainty model for both traffics.
Our application of IQWIG's approach can be criticized for defining an efficiency frontier with treatment regimens, which are not IFN-free and lack a decisive benefit of SOF/RBV and SOF/SMV.
If it occurs, then the efficiency region of each lot is defined by a frontier function ( tilde{t}mapsto {widehat{x}}_{ij}left tilde{t}right) ) in three pieces, first a constant at ( {widehat{x}}_{ij}^0 ), then an affine function, third another constant at ( {widehat{x}}_{ij}^{max } ) characterized by (5.3).
By taking two nearby networks on the frontier one can define a rate of change of efficiency with respect to resilience: <img src="http://journals.plos.org/plosone/article/asset?id=info?doi/10.1371/journal.pone.0013448.e080.PNG" class= inline-graphic"/>.
Addressing such fluctuations defines a current rich frontier for theory and experiment.
