I have published several papers about taoist thought of twofold mystery(重玄) of Cheng Hsuan-Ying(成玄英) who was a taoist master in early Tang dynasty of China. And we could find out three layers of meaning by analyzing twofold mystery thought. Base on those papers, we would compare twofold mystery thought of Cheng Hsuan-Ying with Buddhism madhyamaka thought, and discuss on whether madhyamaka thought contain dialectic dimension or not?Then we will know the differences in both of them. Finally, we point out the significance of twofold mystery thought in this issue.

The long-term performance of plates resting on viscoelastic foundations is a major concern in the analysis of soil-structure interaction. As a powerful mathematical tool, fractional calculus may address these plate-on-foundation problems. In this paper, a fractionalized Zener model is proposed to study the time-dependent behavior of a uniformly loaded rectangular thin foundation plate. By use of the viscoelasticelastic correspondence principle and the Laplace transforms, the analytical solutions were obtained in termsof the Mittag-Leffler function. Through the analysis of a numerical example, the calculated plate deflection, bending moment and foundation reaction were compared to those from ideal elastic and standard viscoelastic models. It is found that the upper and lower bound solutions of the plate response estimated by the proposed model can be determined using the elastic model. Based on a parametric study, the impacts of model parameters on the long-term performance of a foundation plate were systematically investigated. The results show that the two spring stiffnesses govern the upper and lower bound solutions of the plate response. By varying the values of the fractional differential order and the coefficient of viscosity, the timedependent behavior of a foundation plate can be accurately captured. The fractional differential order seems to be dependent on the mechanical properties of the ground soil. A sandy foundation will have a small fractional differential order while in order to simulate the creeping of clay foundation, a larger fractional differential order value is needed. The fractionalized Zener model is capable of accounting for the primary and secondary consolidation processes of the foundation soil and can be used to predict the plateperformance over many decades of time.
Common sorting method have low sorting rates and is sensitive to the Signal-to-Noise Ratio(SNR), detection of time frequency single source point is applied to sort unknown complicated radar signal, high sorting accuracy can be got. The single source points of each radar source signal is detected, then the mixing vector in the corresponding single source point set was estimated by Singular Value Decomposition (SVD), the mixed matrix is estimated simultaneously by cluster validation technique, based on k-means clustering algorithm. Finally, Pulse Description Words (PDW) of each radar signal can be worked out. Experiment results demonstrated that the radar emitter signals extracted by this method showed good performance of noise-resistance and clustering at large-scale SNR.
Bulk samples of K doping K2xFeTe1-xSx with x=0.07, 0.1, 0.2, 0.3 are successfully prepared by using easy-to-use stable compound K2S as the reactant. The lattice constant calculated from X-ray diffraction patterns indicate that K ions enter the Fe-Te-S layers. K doping is beneficial enhance the superconductivity transition temperature from the R-T curves. The apparent diamagnetic signal is observed in M-T curves when the content of K is smaller than 0.1. However, differential curves (dM/dT) in K-rich samples appear sharp slope mutations, which means that the Meissner effect signal is covered by the increased excess ferromagnetic ions. The number of excess Fe magnetic ions is proportional to K content, which may play an important role in determining the superconductivity.
The effect of FeSe doping on the physical properties of MgB2 is studied. Bulk samples of the FeSe doped MgB2 with weight ratio x ðFeSe : MgB2Þ ¼ 0%; 3%; 7% and 10% were prepared by hybrid microwave method. It is proved that FeSe is not stable together with MgB2. Fe2þ enters into MgB2 lattice, some Mg2þ and Se2『 are combined into the new impurity compound MgSe. The superconducting transition temperature (Tc) slightly decreased with increasing doping content of FeSe from R-T and M-T curves, which results from the substitution of Mg2þ by Fe2þ in the MgB2 lattice. The Jc increase slightly with the FeSe doping content increasing from 3 wt % to 10 wt %, which results from the increasing MgSe impurity pinning centers.
Totem culture is a basic culture in all countries. A totem is any supposed entity that watches over or assists a group of people, such as a family, clan, or tribe.(Merriam-Webster Online Dictionary and Webster's New World College Dictionary, Fourth Edition). Totems support larger groups than an individual person. In kinship and descent, if the apical ancestor of a clan is nonhuman, it is called a totem. Normally this belief is accompanied by a totemic myth. And for the ages past, many totems for family. clan and tribe merged in one or two which comes to be a totem culture. We can know many things from the totem of our Ancestors.
This paper presents an experimental study of the behavior of partially concrete encased steel beams (PE beams) under seismic loading. The eff ects of a fl oor slab in providing lateral and torsional support to the strength and ductility of the beam are also investigated herein. One steel beam and six PE beams were tested herein. The strength development in bare steel beam was insuffi cient and signifi cant lateral torsional buckling (LTB) was observed. The concrete encasement of the PE beam delayed the occurrence of LTB and hence increased the strength and ductility of the beam. The plastic rotation capacity of PE beam is enhanced by the additional lateral and torsional support provided on the top of a PE beam. For the beam tested in this study, the concrete encasement permits the beam to reach its plastic strength and have plastic rotation of at least 3.42% rad, which is larger than 2% rad required for Intermediate Moment Frames, when no lateral or torsional support is provided at the top of the beam. To satisfy the 4% rad plastic rotation limitation for special moment frames, lateral support with suffi cient torsional stiff ness is needed.
