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 ...

Provable security refers to the ability to give rigorous mathematical proofs towards the security of a cryptographic construction; in some sense one of the best possible security guarantees one can attain. These proofs are most often given through so-called reductions to a simpler construction or to some well-studied number-theoretic assumption. This thesis deals with two aspects of such reduct...
