It is found that due to the interplay of the d -wave SC and FS, the nonequilibrium hole spin accumulation, differential conductance, and tunneling magnetoresistance exhibit a rich dependence on the Andreev reflection, strengths of potential scattering at the interfaces, mismatches in the effective mass and band between the FS and SC, and types of incident holes, which is much different from that in FS/s -wave SC/FS tunneling junctions. Particularly, it is demonstrated that the differential conductance can be negative in both ferromagnetic and antiferromagnetic alignments for not only incident heavy holes but also incident light holes, and the variations in both the energy gap with temperature and hole spin accumulation with bias voltage can display a twofold behavior due to the Andreev reflection. © 2010 American Institute of Physics.

The synthesized products were characterized by X-ray diffraction patterns (XRD), scanning electron microscopy (SEM), transmission electron micros-copy (TEM), and nitrogen sorption analysis. It was found with increasing the anionic surfactant sodium dodecylsulfate to cetyltrimethylammonium bromide molar ratio, the morphologies of mesoporous silica changed from spherical shape to ellipsoidal shape, at last became rod-like and lamellar shape. Correspondingly the pore diameter and surface area of mesoporous silica all decreased according to nitrogen sorption analysis. The TEM analysis illustrated the product with ordered hexagon mesostructure and homogeneous pore arranged can be obtained, when the molar ratio of cetyltrimethylammonium bromide/sodium dodecylsulfate is 15 : 1. It also demonstrated the less the molar ratio of sodium dodecylsulfate was used, the more ordered pore structure the products exhibited. Furthermore, prolonging the crystal time was beneficial to improve the stability of the product. © Pleiades Publishing, Ltd., 2010.

However, PCL and PLA are incompatible thermodynamically and hence the interfacial properties act as the important roles controlling the final properties of their blends. Thus, in this work, the PCL/PLA blends were prepared by melt mixing using the block copolymers as compatibilizer for the studies of interfacial properties. Several rheological methods and viscoelastic models were used to establish the relations between improved phase morphologies and interfacial properties. The results show that the interfacial behaviors of the PCL/PLA blends highly depend on the interface-located copolymers. The presence of copolymers reduces the interfacial tension and emulsified the phase interface, leading to stabilization of the interface and retarding both the shape relaxation and the elastic interface relaxation. As a result, besides the relaxation of matrices (τ Number of references:52 Main heading:Phase interfaces Controlled terms:Biological materials - Block copolymers - Compatibilizers - Copolymerization - Elasticity - Emulsification - Mechanical properties - Plastic products - Rheology - Viscosity Uncontrolled terms:Blend - Caprolactone - Compatibilization - Compatibilized blends - Diblock copolymer - Elastic interfaces - Interfacial behaviors - Interfacial property - Interfacial tensions - Marangoni stress - matrix - Mechanical strength - Melt mixing - Phase morphology - Poly lactide - Polylactide (PLA) - Relaxation behaviors - Rheological method - Triblock copolymers - Two-component - Viscoelastic models Classification code:951 Materials Science - 931.1 Mechanics - 817.1 Polymer Products - 815 Polymers and Polymer Science - 803 Chemical Agents and Basic Industrial Chemicals - 802.3 Chemical Operations - 801.4 Physical Chemistry - 631.1 Fluid Flow, General - 461.2 Biological Materials and Tissue Engineering - 422 Strength of Building Materials; Test Equipment and Methods - 421 Strength of Building Materials; Mechanical Properties DOI:10.1002/polb.21952 Database:Compendex Compilation and indexing terms, Copyright 2011 Elsevier Inc.

The networks can be described by bipartite graphs, where basic elements, named actors, are taking part in events, organizations or activities, named acts. It is suggested that the subgraphs can be described by so-called k-cliques, which are defined as complete subgraphs of two or more vertices. The k-clique act degree is defined as the number of acts, in which a k-clique takes part. The k-clique act degree distribution in collaboration networks is investigated via a simplified model. The analytic treatment on the model leads to a conclusion that the distribution obeys a so-called shifted power law P(q) ∝ (q + α)-γ where α and γ are constants. This is a very uneven distribution. Numerical simulations have been performed, which show that the model analytic conclusion remains qualitatively correct when the model is revised to approach the real world evolution situation. Some empirical investigation results are presented, which support the model conclusion. We consider the cliques, which take part in the largest number of acts, as the most important ones. With this understanding we are able to distinguish some most important cliques in the real world networks. © 2009 ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.

This paper proposes a scenario model of knowledge transfer for evaluating the efficiency of external technology and knowledge retrieval. The scenario model includes two parts. One is the relation between knowledge resource and knowledge destination, including relation scenario, management scenario, and environment scenario etc. Scenario similarity is proposed for evaluating the feasibility of technology and knowledge transfer in this part. Another is activity scenario and technology scenario. Experts evaluate the infection of this part to knowledge transfer. And then, integrated evaluating result is supplied.
