A protocol to preserve a code of conduct

Abstract: To fight community abuse, we introduce in this paper a set of simple, yet powerful, trust protocols, aimed at enforcing on a P2P network a boolean Code of Conduct verifiable by the network agents themselves. Having a boolean Code of Conduct which honest agents never violate allows effective enforcing of it. A formal model for trust protocol definition and analysis is also defined, and properties of these protocols are formally defined and proved according to this model.

Lateral uniformity of the transport properties of graphene/4H-SiC (0001) interface by nanoscale current measurements

Abstract: Conductive Atomic Force Microscopy was applied to study the lateral uniformity of current transport at the interface between graphene and 4H-SiC, both in the case of epitaxial graphene (EG) grown on the Si face of 4H-SiC and in the case of graphene exfoliated from HOPG and deposited (DG) on the same substrate. This comparison is aimed to investigate the role played by the C-rich buffer layer present at EG/4H-SiC interface and absent in the case of DG/4H-SiC. The distribution of the local Schottky barrier heights at EG/4H-SiC interface (Φ EG ) was compared with the distribution measured at DG/4H-SiC interface (Φ DG ), showing that Φ EG (0.36±0.1eV ) is ˜0.49eV lower than Φ DG (0.85 ± 0.06eV). This difference is explained in terms of the Fermi level pinning ˜0.49eV above the Dirac point in EG, due to the presence of positively charged states at the interface between the Si face of 4H-SiC and the buffer layer.

Towards the extrapolation of the valence‒valence electron partial structure factor for liquid Mg near freezing from a combination of theory and experiment

Abstract: Egelstaff, March, and McGill (1973) proposed the extraction of electron correlation functions in liquids from scattering data. Here, we appeal to computer simulation by de Wijs et al. (1995) on the partial structure factor between ions (i) and valence electrons (v) for liquid Mg near freezing, to write the valence‒valence partial structure factor in terms of and the neutron structure factor , to high accuracy.
