Biometric recognition based on human characteristics for personal identification has attracted great attention. The performance of biometric systems highly depends on the distinctive information in the biometrics. However, identical twins having the closest geneticsbased relationship are expected to have maximum similarity between their biometrics. Classifying identical twins is a challenging p...

To disentangle an independent effect of educational status on mortality risk from direct and indirect selection mechanisms, the authors used a discordant twin pair design, which allowed them to isolate the effect of education by means of adjustment for genetic and environmental confounding per design. The study is based on data from the Danish Twin Registry and Statistics Denmark. Using Cox reg...

Background: Twin low-birth-weight (LBW) neonates are exposed to the increased risk of mortality and morbidity due to poor prognosis. The present study aimed to evaluate the effectiveness of kangaroo mother care (KMC) in the management of twin LBW neonates. Methods: This prospective, observational study was conducted on 150 neonates with the birth weight of

The Chinese National Twin Registry (CNTR), established in 2001, is the first and largest population-based twin registry in China. Based on the CNTR, a new twin cohort was recruited from 2011 to study the relationship between environmental risk factors and chronic diseases. So far, 33,874 twin pairs from nine provinces have been recruited, in which hundreds of disease-discordant twin pairs and e...

in order to investigate deformation history preserved in the calcite twins in the hinterland of zagros, several samples have been collected from calcschists of the paleozoic sargaz complex in the faryab area, se iran. these samples are related to f1-recumbent folding and thrust shear zones. the twin width is about 1 and 3.8 µm (thin-twin regime); the twin strain amounts 5 and 10%; twin intensit...

We report on two cases of prehospital initiated precipitated preterm deliveries with breech presentation, which were completed at the hospital. Case 1 involved a precipitated breech delivery in a multipara, and case 2 an unrecognizeddizygotic (diamniotic, dichorionic) twin pregnancy, with precipitated preterm breech delivery of the first twin, in a multipara.

Happiness and Genes Many scientists have argued that they can determine to what extent human happiness levels are controlled by genes by comparing the average happiness levels of identical twins raised apart. If we discover that identical twins raised apart tend to be more hedonically similar than fraternal twins raised apart, this is interpreted as evidence for the thesis that genes have a str...

As the standard iris biometric algorithm “sees” them, the left and right irises of the same person are as different as irises of unrelated people. Similarly, in terms of iris biometric matching, the eyes of identical twins are as different as irises of unrelated people. The left and right eyes of an individual or the eyes of identical twins are examples of genetically identical irises. In exper...

This study is one which answers many of Dr. Rosenthal's criticisms of earlier work, and in part, it may be seen as an outgrowth of them. Dr. Kringlen's study is in the fine Scandinavian epidemiologic tradition. In addition, his research zeal is apparent in his search for the twins. As would be predicted from the Rosenthal paper, Dr. Kringlen finds much lower concordance rates for schizophrenia ...
