Somatic mutations seem to accumulate slowly with age during adult life in both mice and men. There is, however, a substantial mutant frequency at birth, suggesting that the rate of accumulation is much higher before birth. This suggests that DNA replication plays an important role in the generation of spontaneous mutations. Since most cell division and accompanying DNA replication occurs early ...

Design: Birth data were collected on all births in Michigan from September 11, 2000, to March 11, 2001, and from September 11, 2001, to March 11, 2002. Self-reported ancestry and a name algorithm were used to determine Arab American ethnicity. Unadjusted and adjusted logistic regression analysis was used to assess the relationship between birth before/after September 11 and birth outcomes. Main...

OBJECTIVES To estimate the risk of spontaneous preterm birth in twin pregnancies based on transvaginal sonographic cervical length, fetal fibronectin (fFN) testing, and the gestational age at which these tests were performed. METHODS Women with twin pregnancies, cervical length assessment, and fFN testing between 22 weeks and 31 weeks 6 days in a single maternal-fetal medicine practice from 2...

In the recent past, tracking applications increasingly develop towards distributed sensor scenarios. In many cases, such schemes must cope with low observable targets in cluttered environments. Furthermore, such a setup suffers from communication delays and timely delayed sensor data. However, Track-before-Detect methodologies are not suitable for processing time delayed data yet. In this paper...

Advancements in information and communication technologies have enhanced our possibilities to communicate worldwide, eliminating borders and making it possible to interact with people coming from other cultures like never happened before. Such powerful tools have brought us to reconsider our concept of privacy and social involvement in order to make them fit into this wider environment. It is p...
