We propose an incentive model based on information-hiding to encourage peers to vote for resources in peer-to-peer (P2P) networks. The following are key motives for our model: (1) Some trust and reputation systems have been deployed in modern P2P systems, but a lot of blank rating resources exist in these P2P systems; (2) E-commerce consumer-to-consumer (C2C) websites that adopt simple rating strategies are receiving accusations that false and useless ratings are flooded. We establish an information-hiding based RRR/RIR (resource reputation rating/reputation incentive rating) voting model, which awards or punishes voters according to their behaviors. The RRR generating algorithm and the RIR generating algorithm are presented in detail, and the information-hiding mechanism is given. Experimental results showed that the incentive RRR/RIR model can effectively encourage valid voting and prevent malicious or arbitrary voting in the P2P reputation system.

Tuning magnetic damping constant in dedicated spintronic devices has important scientific and technological implications. Here we report on anisotropic damping in various compositional amorphous CoFeB films grown on GaAs(001) substrates. Measured by a vector network analyzer-ferromagnetic resonance (VNA-FMR) equipment, a giant magnetic damping anisotropy of 385%, i.e., the damping constant increases by about four times, is observed in a 10-nm-thick Co40Fe40B20 film when its magnetization rotates from easy axis to hard axis, accompanied by a large and pure in-plane uniaxial magnetic anisotropy (UMA) with its anisotropic field of about 450 Oe. The distinct damping anisotropy is mainly resulted from anisotropic two-magnon-scattering induced by the interface between the ferromagnetic layer and the substrate, which also generates a significant UMA in the film plane.

Large Hollow nanoparticulate aggregates（LHNAs） based on albumin nanoparticles is a promising technology for developing dry powder inhaler（DPI） with good aerodynamic properties in order to provide a new drug delivery system（DDS） for the treatment of lung disease. Improved understanding of molecular interactions could lead to prepare the DDS rationally. Therefore, this investigation utilized computations and experiments to reveal the mechanisms of budesonide（BUD） interactions with bovine serum albumin（BSA） at the molecular level. The molecular dynamics（MD） simulation revealed that there were three critical stable binding sites of BUD on BSA（P1, P2, P3） mainly by hydrophobic interaction and hydrogen bond. The energy decomposition of each residue to the whole BUD-BSA complex system in P1-P3 showed that nonpolar residues in or around the binding site played an important role in the binding of BUD to BSA. The molar ratio was close to 3 in preparations in drug-loading efficiency experiment, which was confirmed to the simulation results. The details of the binding sites from computation provided a guideline for the design of the BSA nanoparticles carrying BUD, which was prepared successfully at last. Combination of the MD simulation and experiment as well as the mechanism of the molecular interaction provided a solid theoretical basis for the preparation of BSA-LHNAs for DPI in the future.
