  2. 1. Latent variable models for longitudinal twin data

    Author : Annica Dominicus; Juni Palmgren; Nancy L. Pedersen; Michael G. Kenward; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Latent variable models; twin models; variance components; change point models; non-ignorable nonresponse; likelihood ratio tests; Mathematical statistics; Matematisk statistik;

    Abstract : Longitudinal twin data provide important information for exploring sources of variation in human traits. In statistical models for twin data, unobserved genetic and environmental factors influencing the trait are represented by latent variables. In this way, trait variation can be decomposed into genetic and environmental components. READ MORE

  4. 2. Efficient Reconfigurable Multipliers Based on the Twin-Precision Technique

    Author : Magnus Själander; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Reconfigurable; VLSI; Low-Power; Twin-Precision; Multipliers; High-Speed;

    Abstract : During the last decade of integrated electronic design ever more functionality has been integrated onto the same chip, paving the way for having a whole system on a single chip. The strive for ever more functionality increases the demands on circuit designers that have to provide the foundation for all this functionality. READ MORE

  5. 3. Twin-arginine translocation in Yersinia : the substrates and their role in virulence

    Author : Ummehan Avican; Åke Forsberg; Åsa Sjöling; Umeå universitet; []

    Abstract : Pathogenic Yersinia cause a manifold of diseases in humans ranging from mild gastroenteritis (Y. pseudotuberculosis and Y. enterocolitica) to pneumonic and bubonic plague (Y. READ MORE

  6. 4. Autistic-like traits

    Author : Sebastian Lundström; Malmö Rättspsykiatri; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Autism; twin; genetics; Autistic-like traits;

    Abstract : Introduction Autism spectrum disorders (ASDs) are neurodevelopmental disorders characterized by restrictions in social interaction, understanding, and communication, by stereotyped patterns of repetitive behaviors, and by narrow interests. ASDs, which affect about 1% of the population, are predominantly genetic, but no single explanation has been found. READ MORE

  7. 5. Birth Characteristics’ Impacton Future Reproduction and Morbidity Among Twins an dSingletons

    Author : Marie Bladh; Gunilla Sydsjö; Ann Josefsson; John Carstensen; Orvar Finnström; Karin Pettersson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Twin; singleton; preterm birth; SGA; reproduction; hospitalization; siblings;

    Abstract : Globally, in both developed and developing countries, the twinning rates have increased since the early 70’s. A large proportion of twins are born preterm and/or small-for-gestational-age (SGA) and/or with a low birth weight. READ MORE
