Twin-solute, twin-dislocation and twin-twin interactions in magnesium
Journal of Magnesium and Alloys, 2023 Magnesium alloys have received considerable research interest due to their lightweight, high specific strength and excellent castability. However, their plastic deformation is more complicated compared to cubic materials, primarily because their low-symmetry hexagonal close-packed (hcp) crystal structure.

Twin to twin transfusion syndrome [PDF]
Translational Pediatrics, 2021 Twin to twin transfusion syndrome (TTTS) is a common complication that typically presents in the second trimester of pregnancy in 10-15% of monochorionic twins due to net transfer of volume and hormonal substances from one twin to the other across vascular anastomoses on the placenta.

Research with twins: The concept of emergenesis. [PDF]
, 1982 Preliminaty findings from an on-going study of monozygotic twins reared apart (MZA) and data from a larger sample of twins reared together (MZT and DZT), indicate a surprisingly strong influence of genetic variation on aptitudes, psychophysiological ...

Netherlands Twin Register: From Twins to Twin Families [PDF]
Twin Research and Human Genetics, 2006 AbstractIn the late 1980s The Netherlands Twin Register (NTR) was established by recruiting young twins and multiples at birth and by approaching adolescent and young adult twins through city councils. The Adult NTR (ANTR) includes twins, their parents, siblings, spouses and their adult offspring. The number of participants in the ANTR who take part in

On the twin paradox in static spacetimes: I. Schwarzschild metric [PDF]
, 2012 Motivated by a conjecture put forward by Abramowicz and Bajtlik we reconsider the twin paradox in static spacetimes. According to a well known theorem in Lorentzian geometry the longest timelike worldline between two given points is the unique geodesic ...

Twinning in Twin Pedigrees [PDF]
Journal of Epidemiology & Community Health, 1950 age of the mother, and the number of previous children born to her, for all births completely registered. Unfortunately the number of previous children does not give exactly the parity of a birth, as some of the previous children may have resulted from multiple births.

Speaking to twin children: evidence against the "impoverishment" thesis [PDF]
, 2015 It is often claimed that parents’ talk to twins is less rich than talk to singletons and that this delays their language development. This case study suggests that talk to twins need not be impoverished.
