Higher-mode effect on the seismic responses of buildings with viscoelastic dampers

Earthquake Engineering and Engineering Vibration 2002年第1期1卷 119-129页

作者： Meng-Hao tsai Department of civil Engineering Taiwan UniversityChinese Taipei Postdoctoral Research Fellow

In conventional modal analysis procedures,usually only a few dominant modes are required to describe the dynamic behavior of multi-degrees-of-freedom *** number of modes needed in the dynamic analysis depends on the higher-mode contribution to the structural response,which is called the higher-mode *** modal analysis approach, however,may not be directly applied to the dynamic analysis of viscoelastically damped *** is because the dynamic properties of the viscoelastic dampers depend on their vibration ***,the structural stiffness and damping contributed from those dampers would be different for each *** this study,the higher-mode effect is referred to as the response difference induced by the frequency-dependent property of viscoelastic dampers at higher *** analysis procedures for buildings with viscoelastic dampers distributed proportionally and non-proportionally to the stiffness of the buildings are developed to consider the higher-mode *** studies on shear-type viscoelastically damped building models are conducted to examine the accuracy of the proposed procedures and to investigate the significance of the higher-mode effect on their seismic *** damper models are used to estimate the peak damper forces in the proposed procedures. study results reveal that the higher-mode effect is significant for long-period viscoelastically damped *** higher-mode effect on base shear is less significant than on story acceleration *** difference of the seismic response usually occurs at the top ***,the higher-mode effect may not be reduced by decreasing the damping ratio provided by the viscoelastic *** practical application,it is realized that the linear viscous damping model without considering the higher-mode effect may predict larger damper forces and hence,is on the conservative side.

stimulatory effect of trans-cinnamaldehyde on norepinephrine secretion in cultured pheochromocytoma (Pc-12) cells

Acta Pharmacologica sinica 2000年第12期21卷 119-123页

作者： tsai chin-chuan china Medical college Department of Traditional Medicine school of Post-Baccalaureate chinese Medicine Taichung city Taiwan 40401

AIM: The effect of trans-cinnamaldehyde (cNMA) on the release of norepinephrine (NE) from nerve terminal was investigated using rat pheochromocytoma 12 (Pc-12) cells. METHODs: The amount of NA released from Pc-12 cells incubated with cNMA or related substances was quantified by high performance liquid chromatogra-phy (HPLc)-electrochemical detection. The lipophilic anion bisoxonol was used to monitor the effect of cNMA on the membrane potential. REsULTs: cNMA stimulated the secretion of NE in a concentration-dependent manner from 5 μmol/L to 50 μmol/L, while the value of lactate dehydrogenase in the incubated medium was not influenced by cNMA. However, acetaldehyde, cinnam-ic acid, cinnamoyl chloride and cinnamamide failed to produce similar effect. The action of cNMA can thus be considered specific. The depolarizing effect of cNMA on the membrane potential was also illustrated by a concentration-dependent increase in the fluorescence of bisoxonol , a potential-sensitive dye. saxitoxin attenuated the

p73β inhibits transcriptional activities of enhancer I and X promoter in hepatitis B virus more efficiently than p73α

作者： tsai-Ping Li state Key Laboratory of Molecular Biology Institute of Biochemistry and Cell BiologyShanghai Institutes for Biological SciencesChinese Academy of SciencesShanghai 200031China

AIM: p73, as a novel member of a family of p53-related transcription factors, shares redundant functions with p53, such as the abilities of inducing apoptosis and suppressing growth. It is well known that p53 can repress HBV expression and transcription efficiently. The aim of this paper is to investigate the transcriptional effect of p73α and p73β on hepatitis B virus (HBV) and to understand the correlation between HBV and ***: To construct an x-gene inactivated HBV plasmid which was cotransfected with p73α or p73β expression vectors into HepG2 cells. After transiently transfecticn, HBV surface antigen (HBsAg) and HBV e antigen (HBeAg) were detected by ELIsA. Viral transcripts synthesized by HBV were evaluated by Northern blotting analysis. The activities of HBV regulatory elements, including enhancer Ⅰ/X promoter (ENI/Xp) and enhancer Ⅱ/core promoter (ENⅡ/cp) were monitored by luciferase ***: Both p73α and p73β could repress HBsAg and HBeAg expression by downregulating the ENⅠ/Xp and ENⅡ/cp activities. But p73β exerted stronger inhibition on the activity of ENI/Xp than p73α, resulting in much lower level of viral transcripts and the antigens ***: p73β as a novel member of p53 family can efficiently inhibit HBV transcription mainly through downregulating the activities of the HBV ENI/Xp regulatory elements.

Fault tolerant two-step quantum secure direct communication protocol against collective noises

引用

science china(Physics,Mechanics & Astronomy) 2011年第3期54卷 496-501页

作者： tsai chiaWei HWANG Tzonelih Department of computer science and Information Engineering National Cheng Kung University

This work proposes two fault tolerant quantum secure direct communication （QsDc） protocols which are robust against two kinds of collective noises： the collective-dephasing noises and the collective-rotation noises, respectively. The two QsDc protocols are constructed from four-qubit DF states which consist of two logical qubits. The receiver simply performs two Bell state measurements （rather than four-qubit joint measurements） to obtain the secret message. The protocols have qubit efficiency twice that of the other corresponding fault tolerant QsDc protocols. Furthermore, the proposed protocols are free from Trojan horse attacks.
