Intracranial translucency assessment at first trimester nuchal translucency ultrasound
Journal of Medical Imaging and Radiation Oncology, 2016AbstractIntroductionThe antenatal diagnosis of open spina bifida (OSB), a neural tube defect, is predominantly made at the second trimester morphology scan by ultrasound detection of structural abnormalities resulting from the associated Chiari II malformation. Evidence has emerged suggesting that these structural abnormalities can be detected earlier,

Translucency of Monolithic Zirconia After Hydrothermal Aging: A Review of In Vitro Studies.
Journal of Prosthodontics, 2020PURPOSE Recent modifications in composition, structure, and fabrication methods have led to monolithic zirconia ceramics of superior translucency. However, during aging, intrinsic microstructural features such as grain boundaries and pores, may affect ...

Journal of the Society for Information Display, 2005
Abstract— Current LCD designs have about 5–7% transmittance in the white state without the use of DBEF3M (double brightness enhancing film) and up to 10–14% with DBEF film. We presented a design which can further increase the brightness by up to 60%. The basics for this design are new Optiva materials which have a high birefringence about 0.3–0.4 and ...
