OBJECTIVES To examine whether single-nucleotide polymorphisms (SNPs) in VEGFA (-2578 C/A and +936 C/T) associate with small-for-gestational-age (SGA) pregnancies and to identify their effects on first-trimester placental VEGFA expression. DESIGN Multicenter prospective cohort study. SETTINGS Adelaide, Australia, and Auckland, New Zealand. PARTICIPANTS A total of 3234 nulliparous pregnant ...

To reduce the sampling rate in global navigation satellite system (GNSS)-radio occultation receivers, it is essential to establish a suitable estimation of Doppler frequency from the received signal in the satellite onboard receiver. This receiver is usually located on low earth orbit satellite and receives GNSS satellites signal in the occultation situation. The occurred Doppler on the signal ...

OBJECTIVE To evaluate the possible morphological and functional heart injuries in hepatitis C virus patients. METHODS Control-case study analyzing Doppler echocardiographic aspects in 31 hepatitis C virus patients and 20 controls. RESULTS There were no significant difference in relation to the myocardial thickening, left ventricular diameters, circumferential shortening, ejection fraction, ...

Background Preeclampsia is a specific pregnancy syndrome. Early diagnosis and proper administration of preeclampsia can lead to improved maternal and neonatal outcome. We aimed to investigate the uterine artery Doppler ultrasound in predicting the preeclampsia in women with a high-risk pregnancy. Materials and Methods This analytic study was conducted on 160 primigravida women with gestational...

Abstract. The Earth Clouds, Aerosols and Radiation (EarthCARE) satellite mission is a joint effort by the European Space Agency (ESA) Japanese Aerospace Exploration (JAXA). EarthCARE features first spaceborne 94 GHz cloud-profiling radar (CPR) with Doppler capability. raw CPR observations auxiliary information are used as input to three Level-2 (L2) algorithms: (1) C-APC: Antenna Pointing Chara...

Synovial vascularization in metacarpophalangeal joints of a patient with rheumatoid arthritis treated with leukocytapheresis (LCAP) was evaluated by Doppler sonography. After the treatment with LCAP, evaluation with American College of Rheumatology core set showed improvement, and the levels of C-reactive protein and serum amyloid A protein decreased. Power Doppler sonography demonstrated a red...

Wireless communication is the major form of connection nowadays. In most cases it exploits the benefits of the spread spectrum techniques to overcome channel introduced corruptions like Doppler residual frequency, noise, interference and jamming. These techniques also enhance the security and quality of the link. Using long spreading pseudo-noise codes provides further security for the link tho...

in this paper, by considering a squint angle for synthetic aperture radar in the strip-map mode, a method is proposed for estimating parameters of a fixed acceleration moving target. non-zero doppler centroid and range-azimuth coupling in the squint mode add complexity to estimation equations of moving target parameters and cause doppler ambiguity. this, in turn, causes to lose the efficiency o...
