This study describes the potential of wavelength-modulated differential photothermal radiometry (WM-DPTR) for non-invasive invehicle alcohol detection which can be of great importance in reducing alcohol-impaired driving. Ethanol content in the range of concern, 0-100 blood alcohol concentration (BAC) in water phantoms and blood serum diffused in human skin in vitro were measured with high sensitivity. The results show that the WM-DPTR system can be optimized for alcohol detection with the combination of two sensitivity-tuning parameters, amplitude ratio R and phase shift ΔP. WM-DPTR has demonstrated the potential to be developed into a portable alcohol ignition interlock biosensor that could be fitted as a universal accessory in vehicles.
Abstract. The diagnostic value of fenestration itself is limited but it is quite different when fenestration is accompanied by IA. In recent years, the reconstruction model of IA has become the domestic and international hot topic for discussion, however, it is rare to see the research about reconstruction model of IA with fenestration. Based on reliable CT imaging technologies and optimized modeling methods, we successfully reconstruct the 3D digital model of IA with fenestration by applying Mimics software combined with Geomagic studio software. This model can provide a necessary condition for the 3D finite element reconstruction model and computational fluid dynamic analysis, open a new approach for relative clinical hemodynamic study and operative treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
