Three different holographic dark energy models are considered： without the interaction in the non-fiat universe; with interaction in the fiat universe; with interaction in the non-fiat universe. We tlnd that only in the models with the spatial curvature and interaction term proportional to the energy density of matter, it is possible for the weak gravity conjecture to be satisfied. And it seems that the weak gravity conjecture favors an open universe and the decaying of matter into dark energy.展开更多

The research approach used was interpretive approach to qualitative-descriptive methods. Interpretive method emphasizes culture from the perspective of social construction theory （Papa, Danicls, ＆ Spiker, 2008）. Data collection （Mann ＆ Stewart, 2000） conducted through site analysis of the People Justice＇s Party （Parti Kcadilan Rakyat） Malaysia website from January 16 to March 31 2010. The findings of this study arc the website is an effective means to disseminate political party＇s program. Although, the virtual public or party members were preferring a direct face-to-face interpersonal communication. The People Justice＇s Party, Malaysia has 14 MPN （Majclis Pimpinan Negeri/Rcgional Board） in the state-level. Regarding the political atmosphere in Malaysia, the wcbsite was an efficient tool. The costs required were very cheap. Second, the presence of party website opened a space for providing political education to more people. Third, the public responses stimulated improvement and strengthening the political party＇s identity.展开更多

LHD） is composed by Ursula Le Guin as a ＂thought experiment＂ to explore the postgender world on the planet of Gethen. By eradication of sexual difference and embracing the biological fluidity and psychological androgeny, dualism is deconstructed, and a postgender intersubjective space is reconstructed between Genly Ai and Estraven, interluded by cyborg myth and postgenderism culture narratives. Moreover, Le Guin suggests a possible transformation mode ofyin-yang cycle from psychoanalytic light and shadow.展开更多

The high speed cell converter with the switching frequency over MHz behaves as an ideal transformer, and this behavior solves the voltage imbalance issue in the multicellular converter topology. The analysis of the unregulated cell converter is conducted by using the state space averaging method, and the operation condition for the ideal transformer is specified. The behavior of the multicellular DCX using the high speed cell converters has been also analyzed, and the voltage imbalance issue among cell converters is discussed quantitatively. A prototype of a 19.2 kW 384 V-384 V multicellular DCX using sixty-four unregulated cell converters is fabricated and the validity of the analyses is verified.展开更多

The effect of the spatial dimension and the external potential on the JTC are discussed, respectively. These results show that： （i） For the free ideal Bose gas, when n/s ≤ 2 （n is the spatial dimension, s is the momentum index in the relation between the energy and the momentum）, and T → Tc （Tc is the critical temperature）, the JTC can obviously improve by means of changing the throttle valve＇s shape and decreasing the spatial dimension of gases. （ii） For the inhomogeneous external potential, the discriminant △= [1 - y∏^ni=1（kT/εi）^1/tiГ（1/ti＋1）] （k is the Boltzmann Constant, T is the thermodynamic temperature, ε is the external field＇s energy）, is obtained. The potential makes the JTC increase when △ 〉 0, on the contrary, it makes the JTC decrease when A 〈△. （iii） In the homogenous strong external potential, the JTC gets the maximum on the condition of kTεi〈〈1.展开更多

They were sanctified both in imagination and in reality in the early medieval era. Accordingly, spatial studies have been conducted along these two dimensions. The former dimension deals with the numerous abodes of sages and immortals, while the latter examines Buddhist and Taoist monks and the stone chambers and temples or abbeys in which they practiced self-cultivation. In the case of Mount Tiantai, an imagined system of immortals＇ mountain abodes had emerged as early as in the middle of the Eastern Jin dynasty. A specific immortal was Wang Ziqiao, the Perfected of Mount Tongbai, who had authority over the Jinting palace and administration. The imagining of immortals＇ abodes not only helped the Taoists determine the locations of Taoist abbeys, but also inspired monks who hoped to practice self-cultivation with the help of the powers of mountain gods and immortals. In a sense, this was a process in which knowledge of the immortals shaped the landscape of Buddhist temples and Taoist abbeys.展开更多
