DOI: 10.1002/sim.9677
Abstract: Incorporating promising biomarkers into cancer screening practices for early‐detection is increasingly appealing because of the unsatisfactory performance of current cancer screening strategies. The matched case‐control design is commonly adopted in biomarker development studies to evaluate… read more here.

DOI: 10.1007/s12555-017-0539-7
Abstract: When a complex task has to be performed by multiple systems, it imposes functional dependencies between the states and/or outputs of the systems. These functional dependencies create a system of’ virtually’ interconnected subsystems, even though… read more here.
