5-7-5 line defects onAs∕Si(100): A general stress-relief mechanism for V/IV surfaces

Spin Filtering in Zigzag Graphene Nanoribbons Using 7-5 Defects

Electrons carry both charge and spin. The processing of information in conventional electronic devices is based only on the electronic charge. Spin electronics, or spintronics, uses the spin of electrons as another degree of freedom [1]. Materials with zero band gap form the basis for spintronic devices and show superior performance in comparison with non-zero band gap materials [1]. Graphene, ...

5 Constrained Willmore Surfaces

We develop the basics of a theory of constrained Willmore surfaces. These are the critical points of the Willmore functional W = ∫ HdA restricted to the class of conformal immersions of a fixed Riemann surface. The class of constrained Willmore surfaces is invariant under Möbius transformations of the ambient space. Examples include all constant mean curvature surfaces in space forms.

Molecular mechanism for Rabex-5 GEF activation by Rabaptin-5

Rabex-5 and Rabaptin-5 function together to activate Rab5 and further promote early endosomal fusion in endocytosis. The Rabex-5 GEF activity is autoinhibited by the Rabex-5 CC domain (Rabex-5CC) and activated by the Rabaptin-5 C2-1 domain (Rabaptin-5C21) with yet unknown mechanism. We report here the crystal structures of Rabex-5 in complex with the dimeric Rabaptin-5C21 (Rabaptin-5C212) and i...
