The Chinese Hospitality Industry: A perspective article

This paper illustrates the logics shifting in the Chinese hotel industry since1949 and offers a better understanding of how and why the Chinese hotel industry has evolved into its present situation. The logic evolution and future trends in this market were also discussed

Quantum State Reconstruction of Many Body System Based on Complete Set of Quantum Correlations Reduced by Symmetry

We propose and study a universal approach for the reconstruction of quantum states of many body systems from symmetry analysis. The concept of minimal complete set of quantum correlation functions (MCSQCF) is introduced to describe the state reconstruction. As an experimentally feasible physical object, the MCSQCF is mathematically defined through the minimal complete subspace of observables determined by the symmetry of quantum states under consideration. An example with broken symmetry is analyzed in detail to illustrate the idea.Comment: 10 pages, n figures, Revte

Transport Measurements on Nano-engineered Two Dimensional Superconducting Wire Networks

Superconducting triangular Nb wire networks with high normal-state resistance are fabricated by using a negative tone hydrogen silsesquioxane (HSQ) resist. Robust magnetoresistance oscillations are observed up to high magnetic fields and maintained at low temperatures, due to the eective reduction of wire dimensions. Well-defined dips appear at integral and rational values (1/2, 1/3, 1/4) of the reduced flux f = Phi/Phi_0, which is the first observation in the triangular wire networks. These results are well consistent with theoretical calculations for the reduced critical temperature as a function of f.Comment: 4 pages, 3 figure

A Ordem de Cristo no contexto de uma economia de mercês. Critérios de provimento de cargos e ofícios nos séculos XVII e XVIII: o caso da capitania do Espírito Santo

Neste trabalho, partimos do conceito original de ordem religioso-militar e dissertamos sobre a história da Ordem de Cristo, a qual identificamos e descrevemos as origens medievais como ordem religioso-militar e a sua criação ou fundação por necessidade estratégica da monarquia portuguesa para proteger e manter o patrimônio templário no território português. Seguimos para a descrição de um panorama do Brasil colonial inserido no Império ultramarino português, as suas estruturas e práticas político-administrativas com ênfase no sistema de capitanias hereditárias e do governo-geral criados pela monarquia portuguesa. Apresentamos a discussão da dualidade MetrópoleColônia e a busca do controle político e administrativo periférico pelo centro do poder português. Em continuação, abordamos a consolidação de uma economia de mercês, que atuava na seleção de servidores para a burocracia no reino e nas conquistas ultramarinas portuguesas. Assim, na época moderna desenha-se um novo modelo de cavaleiro das ordens militares que se definia como servidor destacado do rei, limpo de sangue e com cabedal que lhe permitisse não sujar as mãos com trabalho e então o interesse nas ordens militares, em particular pelo hábito da Ordem de Cristo, generaliza-se por toda a sociedade portuguesa. Concluindo o trabalho, caracterizamos a formação da capitania do Espírito Santo e a partir de fontes manuscritas e impressas que abarcam os séculos XVII e XVIII dissertamos sobre as inflexões de uma economia de mercês que se consolidava e sobre a presença da Ordem de Cristo em um contexto regional de provimento de cargos e ofícios na capitania do Espírito Santo

Controllable Laser Ion Acceleration

In this paper a future laser ion accelerator is discussed to make the laser-based ion accelerator compact and controllable. Especially a collimation device is focused in this paper. The future laser ion accelerator should have an ion source, ion collimators, ion beam bunchers, and ion post acceleration devices [Laser Therapy 22, 103(2013)]: the ion particle energy and the ion energy spectrum are controlled to meet requirements for a future compact laser ion accelerator for ion cancer therapy or for other purposes. The energy efficiency from the laser to ions is improved by using a solid target with a fine sub-wavelength structure or a near-critical density gas plasma. The ion beam collimation is performed by holes behind the solid target or a multi-layered solid target. The control of the ion energy spectrum and the ion particle energy, and the ion beam bunching would be successfully realized by a multistage laser-target interaction

Partial Wave Analysis of J/ψ→γ(K+K−π+π−)J/\psi \to \gamma (K^+K^-\pi^+\pi^-)

BES data on $J/\psi \to \gamma (K^+K^-\pi^+\pi^-)$ are presented. The $K^*\bar K^*$ contribution peaks strongly near threshold. It is fitted with a broad $0^{-+}$ resonance with mass $M = 1800 \pm 100$ MeV, width $\Gamma = 500 \pm 200$ MeV. A broad $2^{++}$ resonance peaking at 2020 MeV is also required with width $\sim 500$ MeV. There is further evidence for a $2^{-+}$ component peaking at 2.55 GeV. The non-$K^*\bar K^*$ contribution is close to phase space; it peaks at 2.6 GeV and is very different from $K^{*}\bar{K^{*}}$.Comment: 15 pages, 6 figures, 1 table, Submitted to PL
