Netherlands Twin Register: From Twins to Twin Families [PDF]

open access: yesTwin 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

Codistances of 3-spherical buildings [PDF]

open access: yes, 2011
We show that a 3-spherical building in which each rank 2 residue is connected far away from a chamber, and each rank 3 residue is simply 2-connected far away from a chamber, admits a twinning (i.e., is one half of a twin building) as soon as it admits a ...

Modeling the deformation textures and microstructural evolutions of a Fe–Mn–C TWIP steel during tensile and shear testing [PDF]

open access: yes, 2012
The high manganese austenitic steels with low stacking fault energy (SFE) present outstanding mechanical properties due to the occurrence of two strain mechanisms: dislocation glide and twinning. Both mechanisms are anisotropic.

Twin-solute, twin-dislocation and twin-twin interactions in magnesium

open access: yesJournal 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.

Texture, twinning and metastable "tetragonal" phase in ultrathin films of HfO2 on a Si substrate [PDF]

open access: yes, 2009
Thin HfO<sub>2</sub> films grown on the lightly oxidised surface of (100) Si wafers have been examined using dark-field transmission electron microscopy and selected area electron diffraction in plan view.

Twinning in Twin Pedigrees [PDF]

open access: yesJournal 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.

Crystallography of deformation twinning in hexagonal close-packed metals. Revisiting the case of the (56 deg, a) contraction twins in magnesium

open access: yes, 2016
Contraction twinning in magnesium alloys leads to new grains that are misoriented from the parent grain by a rotation of 56 deg around the a-axis. The classical theory of deformation twinning does not precise the atomic displacements and does not explain

Twinning to slip transition in ultrathin BCC Fe nanowires

open access: yes, 2018
We report twinning to slip transition with decreasing size and increasing temperature in ultrathin $$ BCC Fe nanowires. Molecular dynamics simulations have been performed on different nanowire size in the range 0.404-3.634 nm at temperatures ranging from

Atomic displacements accompanying deformation twinning: shears and shuffles [PDF]

open access: yes, 2016
Deformation twins grow by the motion of disconnections along their interfaces, thereby coupling shear with migration. Atomic-scale simulations of this mechanism have advanced to the point where the trajectory of each atom can be followed as it transits ...
