The molecular rotor 9-(2-Carboxy-2-cyanovinyl)julolidine (CCVJ) exists in two isomers. While the E isomer, which is present absence of light, yields a fluorescent behavior, Z isomer photoproduct with no detectable luminescence. This regenerative behavior utilized for Molecular Tagging Velocimetry (MTV).

In the magnetic plasma fusion community and solar physics research community, different velocimetry algorithms have been used. Those are: orthogonal dynamic programing based particle image (ODP-PIV) local correlation tracking (LCT), respectively. this paper, a systematic comparison of these codes is performed using synthetically produced turbulence data. The spatial scale typical pattern scanne...

This paper presents the design and implementation of velocimetry techniques applicable to the analysis of microfluidic systems. The application of both micronresolution particle image velocimetry (micro-PIV) and particle tracking velocimetry (PTV) to the measurement of velocity fields within micromachined fluidic channels is presented. The particle tracking system uses epifluorescent microscopy...

In pregnant women, antiphospholipid syndrome (APS) is associated with an increased risk of preeclampsia, fetal intrauterine growth restriction, and other complications related to uteroplacental insufficiency. In the last two decades, several studies were performed to identify the predictive role of some parameters in relation to obstetric outcome in APS patients. Among these, the uterine veloci...

Fifty-three high-risk pregnancies were followed up serially with Doppler velocimetry of the umbilical artery and uterine vessels from early on to investigate whether abnormalities in Doppler waveforms can predict the outcome of pregnancy accurately before other clinical signs develop. Results of Doppler velocimetry were withheld from the clinicians managing the patients. When the absence of end...

OBJECTIVES To evaluate placental volume and vascular indices in pregnancies with severe fetal growth restriction and determine their correlations to normal reference ranges and Doppler velocimetry results of uterine and umbilical arteries. METHODS Twenty-seven fetuses with estimated weights below the 3rd percentile for gestational age were evaluated. Placental volume and vascular indices, inc...
