This work is motivated by the engineering task of achieving a near state-of-the-art face recognition on a minimal computing budget running on an embedded system. Our main technical contribution centers around a novel training method, called Multibatch, for similarity learning, i.e., for the task of generating an invariant “face signature” through training(More)
To discover whether first-trimester spontaneous abortion can be predicted by embryonic heart rate (EHR), we performed a cross-sectional study during the first trimester of pregnancy using high-frequency transvaginal sonography combined with pulsed Doppler. Heart rate was measured in 603 embryos; of these, 580 continued beyond 13 weeks' gestation and 23(More)
OBJECTIVE To assess the prevalence and incidence of postnatal depression and its relation to certain psychosocial factors. METHOD A questionnaire was administered to 327 randomly selected pregnant women on the first or second postpartum day A and again 6 to 12 weeks later B. The questionnaire comprised a psychosocial and demographic self-report, and the(More)
Congenital fibrosarcoma is a rare soft tissue sarcoma. A 22-year-old woman in the 22nd week of her first pregnancy underwent sonographic examination, which revealed a soft tissue swelling of the fetus's left thigh. The pregnancy was terminated, and congenital fibrosarcoma was diagnosed by pathologic examination. To our knowledge, this is the first published(More)
Ultrasound is a sensitive tool for the diagnosis of fetal anomalies during the prenatal period. Most knowledge about the ultrasound images of such anomalies is based on abdominal scanning during the second trimester of pregnancy. The value of transvaginal sonography for evaluating fetal anomalies and a comparison with transabdominal sonography in the first(More)
Two distinct ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) small subunit (SSU) populations were observed in Pteris vittata gametophytes grown under different illumination conditions. Exposure of the fern gametophytes to continuous red light (R) resulted in Rubisco SSUs that were not recognized by polyclonal antibodies raised against SSUs from(More)
Umbilical artery velocity waves were obtained by Doppler ultrasonography before, during, and after 20 episodes of fetal heart rate (FHR) variable decelerations (VD) during the active stage of labor in 8 women. During 50% of the VD periods, the umbilical artery resistance flow parameters increased significantly (p < 0.01). The increase in resistance preceded(More)
A 28-year-old woman, gravida 7, para 6, was referred at 21 weeks' gestation to our ultrasound unit because of bilateral fetal lower limb edema diagnosed previously. Ultrasonography showed a constriction ring around both legs, and, with the aid of color Doppler, arterial flow was demonstrated in both legs beneath the constriction ring. Subsequent(More)
OBJECTIVES To determine at which gestational age the ultrasound finding of a breech presentation should compel us to follow the pregnancy more closely with repeat ultrasound examinations. METHODS A retrospective longitudinal investigation of ultrasound examinations in the second and third trimesters is reported. The study group consisted of 157 breech(More)
