弱凸和强凸模糊映射

在两个凸集之间引入了弱凸模糊映射和强凸模糊映射的概念．指出强凸模糊映射为弱凸模糊映射;凸映射一定为强凸模糊映射,若一个普通映射为弱凸模糊映射,则它一定为凸映射．征明了两个凸模糊子集可以确定一个弱凸模糊映射;两个弱（强）凸模糊映射的合成仍为弱（强）凸模糊映射;一个凸模糊子集在一个弱凸模糊映射之下的象和原象仍为凸模糊子集．

不变反凸模糊集

研究了不变反凸模糊集及其相关性质,推广了有关文献中反凸模糊集的概念和相关结论.首先,通过将不变凸集的思想应用到反凸模糊集,定义了一种新的广义反凸模糊集——不变反凸模糊集:设A∈F(Rn),称A为不变反凸模糊集,若存在映射η:Rn×Rn→Rn,有A(y+αη(x,y))≤A(x)∨ A(y),(V) x,y∈Rn,(V)α∈[0,1].然后,探讨了反凸模糊集与不变反凸模糊集的关系:当η(x,y) =x-y时,不变反凸模糊集就退化为反凸模糊集,显然,反凸模糊集成为不变反凸模糊集的特例；通过构造例子说明不变反凸模糊集不是反凸模糊集,得到不变反凸模糊集是反凸模糊集的真推广的结论.根据不变反凸模糊集的定义,研究了不变反凸模糊集的并、稠密性等性质以及模糊集成为不变反凸模糊集的条件.最后,类似于不变反凸模糊集,分别探讨了模糊集成为不变强反凸模糊集和不变严格反凸模糊集的条件.

诗与"在"--海德格尔诗学的阐释

海德格尔对荷尔德林诗歌的阐释，目的是进行诗与思的对话，归根结底还是探讨存在。诗与“在”的关系，是海氏诗学框架的核心内容，诗与“在”的关系又进一步引申为艺术与真理的关系，本从真理如何被遮蔽的问题入手，试图读解海德格尔诗学的内涵。艺术是无蔽的真理显明的一种方式，诗是危机的拯救，语言是存在的家园。海德格尔对诗与在的探讨最后又转入了对语言的探讨，无法走出语言的牢笼。只有在实践中，把艺术变成为社会变革的一个因素，才可以解放被传统理性压迫的力量，显现艺术的真理，确立艺术的价值。     

Regulation of canonical Wnt/β-catenin pathway in the nucleus

Canonical Wnt/β-catenin pathway plays a central role in development, homeostasis, as well as tumorigenesis. The regulation of the pathway involves various and complicated mechanisms, including the extracellular, intracellular and endonuclear regulation. As the key component of the pathway, the Lefl/Tcfs-β-catenin complex is also the key target of regulation in the nucleus. In the current review, we are going to summarize the regulators in the nucleus which can modify the transcrip- tional activity of the Wnt/β-catenin pathway.     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

论信托财产的人格性

信托财产是信托关系的基本要素,由于信托的特殊性,信托财产与传统民法的财产有很大区别,正确给信托财产定位,是信托业得以健康发展的核心问题。信托财产的特性在于其人格性,而这种人格性的赋予是以交易成本最小化为动因,尽管信托财产人格性设计对受益人的利益有偏袒,但从社会成本而言,其目的在于促使交易成本最小化,当然,对信托财产的人格性不能绝对化,由于利益平衡的需求,往往在特定情况下对信托财产予以人格否认。     

卤素离子在多晶铜电极表面的微分电容研究

本文通过测量金属晶体电极表面的微分电容研究了金属电极表面在金属与水溶液界面上的吸附能力,以及金属与吸附质之间的相互作用。文中论述了多晶铜电极在(0.5-x)mNaClO_4+xmNaBr的一系列不同x值的溶液中的微分电容测量值及微分电容-电位曲线,证明了F~-和ClO_4~-离子在多晶铜电极表面是非常弱的吸附,Br~-离子在多晶铜电极表面具有特定的吸附,每条电容-电位曲线有一个凸起的峰。在峰所对应的位能值,金属表面对阴离子的吸附能力强,证实金属-吸附质之间的相互作用强,吸附的阴离子在过渡层中散射导电电子的能力也强。对于相同阴离子和金属的体系,其微分电容与吸附质的浓度、电压、溶液的pH值和表面的非均匀性等因素密切有关。研究证明,金属晶体电极表面在电解质溶液中的微分电容的变化规律类似于表面电反射信号的强弱变化规律,微分电容大小取决于金属-吸附质之间的电荷转移程度。     

气体对阴离子表活剂压裂液破胶实验研究

阴离子表活剂压裂液是新型清洁压裂液,原油和地层水对其破胶机理与实验研究已相当充分,但气体对其破胶作用至今研究很少.为解决阴离子表活剂压裂液在压裂应用中的障碍,研究采用一套实用的实验流程,评价了天然气、氮气、二氧化碳三种常见气体对阴离子表活剂压裂液的影响.实验证明,三种不同的气体对阴离子表活剂压裂液的降粘幅度存在较大的差别,其中,二氧化碳气体对阴离子清洁压裂液降粘幅度最大,可使交联液体彻底破胶,天然气对阴离子型表活剂压裂液降粘幅度较小,氮气对阴离子压裂液的粘度几乎没有影响,氮气和天然气可以使液体泡沫化,从而有利于返排.实验结果为优化压裂设计提供了依据,可有效提高现场压裂施工成功率.

DEM/CFD modelling of the deposition of dilute granular systems in a vertical container

Deposition of granular materials into a container is a general industrial packing process. In this study, the deposition behaviour of dilute granular mixtures consisting of two types of particles that were of the same particle size but different particle densities in the presence of air was numerically analyzed using a coupled discrete element method （DEM） and computational fluid dynamics （CFD）. Bilayer granular mixtures with light particles at bottom and heavy particles at top were first simulated. It was found that the presence of air significantly affected the flow behaviour of the bilayer mixtures. For the system with a relatively low initial void fraction, the air entrapped inside the container escaped through the dilated zones induced due to the friction between the powder bed and wall surfaces. The escaping air streams entrained light particles that were originally located at the bottom of the granular system. Consequently, these light particles were migrated to the top of the granular bed at the end of deposition process. More light particles were migrated when the deposition distance was increased. For the system with a high initial void fraction, some light particles penetrated into the top layer of heavy particles and created a mixing zone. Deposition of random mixtures with different initial void fractions was also investigated and the influence of initial void fraction on the segregation behaviour was explored as well. It was found that the increase of void fraction promoted segregation during the deposition in air. It was demonstrated that, for granular mixtures consisting of particles of different air sensitivities, the presence of air had a significant impact on the mixing and segregation behaviour during the deposition.     

Using new fusion operations to improve trust expressiveness of subjective logic

Subjective logic provides a means to describe the trust relationship of the real world.However,existing fusion operations it offers treat fused opinions equally,which makes it impossible to deal with the weighted opinions effectively.A.Jφsang presents a solution,which combines the discounting operator and the fusion operator to produce the consensus to the problem.In this paper,we prove that this approach is unsuitable to deal with the weighted opinions because it increases the uncertainty of the consensus.To address the problem,we propose two novel fusion operators that are capable of fusing opinions according to the weight of opinion in a fair way,and one of the strengths of them is improving the trust expressiveness of subjective logic.Furthermore,we present the justification on their definitions with the mapping between the evidence space and the opinion space.Comparisons between existing operators and the ones we proposed show the effectiveness of our new fusion operations.
