Bridging the gap: Multi‐stakeholder perspectives of molecular diagnostics in oncology

Molecular Oncology, EarlyView.
Although molecular diagnostics is transforming cancer care, implementing novel technologies remains challenging. This study identifies unmet needs and technology requirements through a two‐step stakeholder involvement. Liquid biopsies for monitoring applications and predictive biomarker testing emerge as key unmet needs. Technology requirements vary by

Performance Characterization of a Valveless Pulse Detonation Engine

41st Aerospace Sciences Meeting and Exhibit, 2003
A valveless pulse detonation engine geometry has been partially evaluated on a direct-connect test stand at simulated inlet flight conditions to the combustor. The geometry utilizes a fuel/oxygenenriched air initiator to initiate detonations in the main combustor and has been operated on ethylene, propane, and JP-IO.

Detonation driver for enhancing shock tube performance [PDF]

Shock Waves, 2003
The development of a shock-induced detonation driver for enhancing the performance of a shock tube is described. The detonation wave is induced by the expansion of helium or air. Various gaseous fuel-oxidizer combinations are examined. This method produces a detonation wave which propagates downstream that transitions into a shock wave in the driven ...

Detonation performance measurements of cyclotol 80/20 [PDF]

AIP Conference Proceedings, 2017
Cyclotol is a melt-castable high explosive composed of RDX and TNT, and typically a small amount of HMX. The term Cyclotol may apply to other mixtures of these components, but for the present work, experiments were conducted using Cyclotol containing 80 wt% RDX and HMX and 20 wt% TNT (we will refer to mixtures of RDX and TNT using the notation RDX%/TNT%
