Using a web-based application to define the accuracy of diagnostic tests when the gold standard is imperfect.

PLoS ONE, 2013
BackgroundEstimates of the sensitivity and specificity for new diagnostic tests based on evaluation against a known gold standard are imprecise when the accuracy of the gold standard is imperfect.

Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid

Advanced Engineering Materials, EarlyView.
A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an

Seismic Meta‐Foundations With Imperfect Interfaces

Earthquake Engineering & Structural Dynamics
ABSTRACTSeismic wave isolation through layered meta‐foundations is an emerging area of research, driven by its intrinsic theoretical significance and potential practical applications. To date, the complexities associated with imperfect interfaces have often been overlooked in the development of analytical frameworks, which tend to prioritize simple yet
