A method is reported by which the "in utero" crownrump length of the fetus may be determined by sonar in the first trimester of pregnancy. The accuracy of the technique was assessed by comparing the sonar and the direct postabortum measurements of fetuses in cases of missed abortion. A normal curve of fetal crown-rump length was derived from 214 examinations on 80 patients and by using these va...

In this paper a simple algebraic formula is obtained for the correspondence between finite right nilpotent Fp-braces and pre-Lie algebras. This agrees with using Lazard's algebras proposed by Wolfgang Rump in 2014. As an application example, classification of all generated one element cardinality p4 obtained. It also shown that sum number left ideals brace ideal, therefore every contains larges...

We prove in the random oracle model that OAEP++, which was proposed by us at the rump session of Asiacrypt 2000, can generate IND-CCA2 ciphers using deterministic OW-CPA cryptographic primitives. Note that OAEP++ differs from OAEP proposed by Jonsson in [4]. While OAEP requires a non-malleable block cipher, OAEP++ does not require such additional functions. The security reduction of OAEP++ is a...

Methods A total of 1490 pregnant women were assessed for first trimester ultrasonography. They had routinely measured crown-rump length (CRL) and nuchal translucency (NT) for screening for Down syndrome between 11 and 14 weeks of gestation. Cases with a NT≥3 mm were counselled further regarding the risk of chromosomal abnormality and prenatal diagnosis by fetal karyotyping. A complete follow-up...
