Influence of diesel surrogates on the behavior of simplified spray models [PDF]

, 2012
Numerous experimental investigations make use of diesel surrogates to make the computational time reasonable. In the few studies where measured (surrogate and real diesel) and computed (surrogate only) results have been compared, the selection ...

A general approach to risk modeling using partial surrogate markers with application to perioperative acute kidney injury

Diagnostic and Prognostic Research, 2017
Background Surrogate outcomes are often utilized when disease outcomes are difficult to directly measure. When a biological threshold effect exists, surrogate outcomes may only represent disease in specific subpopulations.
