Study of abnormal umbilical artery doppler and neonatal outcome

Asian Journal of Medical Sciences, 2019
Background: Doppler provides assessment of uteroplacental and fetoplacental circulation during pregnancy. It is a sensitive tool in early detection of fetal compromise and allows needful intervention. Aims and Objective: To study the role of umbilical

Is pathological fetal Doppler cerebroplacental ratio (CPR) associated with adverse delivery outcomes in pregnancies complicated by fetal growth restriction undergoing labor induction? A retrospective cohort study

International Journal of Gynecology &Obstetrics, Volume 172, Issue 3, Page 1729-1734, March 2026.
Abstract Objective The optimal delivery approach for fetal growth restriction (FGR) with pathological cerebroplacental ratio (CPR) remains uncertain. This study evaluated the association between isolated pathological CPR (<5th percentile) and delivery outcomes, specifically the rate of cesarean delivery (CD) due to non‐reassuring fetal heart rate ...

Full-field interferometry using infinity corrected optics [PDF]

, 2015
In this paper the construction of full-field (imaging) interferometers using infinity corrected optics commonly used in microscopy is discussed, with an emphasis on self-mixing interferometry configurations where the imaged light field is mixed with ...

Numerical Simulations of Very Low Velocity Impacts and Ignition of an Explosive Confined by a Thin Case

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 3, Page 446-455, March 2026.
A low‐speed impact (around one meter per second) of a metallic tip on an explosive confined by a thin plate is simulated. The heat due to friction between the tip and the plate and the one due to the deformation of the plate are not transfered to the ignited zone.

Evaluation of fetal middle cerebral artery Doppler indices in pregnancies with intrauterine growth restriction: A cross-sectional study

National Journal of Physiology, Pharmacy and Pharmacology, 2017
Background: Doppler velocimetry studies of placental and fetal circulation can provide important information regarding fetal well-being providing an opportunity to improve fetal outcome. Aims and Objective: The aim of this study to evaluate the role of

All-Optical Broadband Excitation of the Motional State of Trapped Ions

, 2012
We have developed a novel all-optical broadband scheme for exciting, amplifying and measuring the secular motion of ions in a radio frequency trap. Oscillation induced by optical excitation has been coherently amplified to precisely control and measure ...
