Functional polymorphisms in the TERT promoter are associated with risk of serious ovarian and breast cancer Jonathan Beesley, Hilda Pickett, Sharon Johnatty, Xiaoqing Chen, Jun Jun Li, David Rider, Michael Stutz, Diether Lambrecht, Jenny Chang-Claude, Thilo Dork, Marc Goodman, Bart Kiemmney, Elisa Bandera, Linda Kelemen, Shan Wang-Gorke, Ian Campbell, Simon Gayther, Susan Ramus, Ellen Goode, Ro...
is a reduced-order kinetic model to reproduce the Navier-Stokes hydrodynamics (and beyond) at a macroscopic level. Since the pioneering work of McNamura and Zanetti (1988), the LB method has been extended to various complex flows involving, for example, multicomponent and interfacial phenomena , and has been particularly successful for multiphase flows in complex geometry and porous media (Succ...
Well-preserved, actively deforming folds in the Tien Shan of Kyrgyzstan provide a natural laboratory for the study of the evolution of thrust-related folds. The uplifted limbs of these folds comprise weakly indurated Cenozoic strata that mantle well-lithified Palaeozoic bedrock. Their contact is a regionally extensive unconformity that provides a persistent and readily traceable marker horizon....
Hardness and plastic deformation during Vickers indentation in as-cast, annealed, and fully crystallized Zr57Cu27Al11Ni5 bulk metallic glass was examined. Subsurface deformation morphology under the indenter tip was studied at various loads and for different annealing time. Appreciable plastic deformation, through shear banding, occurs in the as-cast and annealed alloys. Two different types of ...

To produce carbonate apatite (CAP) ceramics with the desired complex shapes using superplastic deformation, deformation behavior of CAP ceramics under constant loading as well as physical properties after deformation were evaluated. Sintered CAP ceramics were plastically deformed in an electric furnace attached to a universal hydraulic testing machine under a constant load. CAP ceramics subject...
The structure feature of a model CuZr metallic glass during deformation is investigated by molecular dynamics simulations. A spatially heterogeneous irreversible rearrangement is observed in terms of nonaffine displacement. We find that regions with smaller nonaffine displacement have more Voronoi pentagons, while in those with larger nonaffine displacement other types of faces are more populat...
We report a close correlation between the dynamic behavior of serrated flow and the plasticity in metallic glasses (MGs) and show that the plastic deformation of ductile MGs can evolve into a self-organized critical state characterized by the power-law distribution of shear avalanches. A stick-slip model considering the interaction of multiple shear bands is presented to reveal complex scale-fr...
Intermetallic precipitates are widely used to tailor mechanical properties of structural alloys but are often destabilized during plastic deformation. Using atomistic simulations, we elucidate structural instability mechanisms of intermetallic precipitates associated with dislocation motion in a model system of Al2Cu. Interaction of non-coplanar <001> dislocation dipoles during plastic deformat...
