Quantum computation with trapped ions in an optical cavity

Two-qubit logical gates are proposed on the basis of two atoms trapped in a cavity setup. Losses in the interaction by spontaneous transitions are efficiently suppressed by employing adiabatic transitions and the Zeno effect. Dynamical and geometrical conditional phase gates are suggested. This method provides fidelity and a success rate of its gates very close to unity. Hence, it is suitable for performing quantum computation.Comment: 4 pages, 5 figures, REVTEX, second part modified, typos correcte

Kualitas Pelayanan B Us R Apid T Ransit (Brt) Trans Semarang Pada Koridor I Dan II

Increasing number of people who have a personal vehicle, but not matched by thedevelopment of an adequate road infrastructure, so that in large citiessuch as Semarang obviouscongestion that resulted in less effective and efficient in doing activities. In general, there are threedimensions that determines the mobility of public transport, namely the dimensions of evaluation ofservices, which will be determined by the user, the dimensions of service performance that is more interms of the owner (operator) public transport, and the dimensions of government policy (regulator ).This study suggests the quality of services Trans Semarang BRT corridor I andII, as both the corridoris a corridor crowded passenger of the other corridors.Methods of data analysis used in this research is to use a qualitative method with purposivesampling. In this research, data collection techniques used were observation or observation, interviewand documentation. The location of research is shelter in the corridors I and II.In this study covers two related, namely, the BRT Trans Semarang infrastructure and qualityof service on the corridor I and II. The discussion surrounding infrastructure on fleet size, condition ofthe fleet, the number of shelters and shelter conditions in the corridor I and II. Discussion on thequality of services includes about speed, convenience's security, and affordability of access to shelterandtravel expenses to be paid passengers.Conclusion The study shows First, the quality of service on the BRT Trans Semarang both interms of infrastructure as well as managing the BRT is good that the indicator can be seen from thenumber of fleets, accessto shelter, and concierge services. In addition, the number of passengers in thecorridor I and II increased. Second, On the condition of shelter BRT corridor I and II both in terms ofthe conditions of service and personnel, passengers give positive feedback. Only in rush hour full stopso that passengers crowded, so it needs the expansion of shelter in dense areas of passengers. As forequalization shelter in the corridor I and II has been uneven, which makes passenger access easier touse BRT

The effect of landmarks on visitors' attachment towards the historic city of Banda Hilir, Melaka

Landmarks are strongly associated with tourism activities as they are regarded as the main attraction of a city. Due to the increase in new development, the attraction of landmarks is diluted. A similar threat is observed in Banda Hilir, Melaka, whereby new commercial buildings have dominated the overall structure of the historic city. As a result, its sense of place is diminishing, which may affect the visitors’ sense of attachment and belonging. This paper discusses the visitors’ attachment to the landmarks in Banda Hilir. Face-to-face interviews are conducted with visitors to understand their sense of attachment to the landmarks identified in the study. The results indicate that the visitors’ attachment differs and is influenced by the physical characteristics of the historical landmarks, the length of engagement and familiarity with the places. They are more attached to landmarks with dominating physical appearance that make them more memorable. The findings indicate the importance of visitors’ attachment in enhancing the attraction of landmarks within tourism attraction sites and as a guide when managing the redevelopment project for a historic town or city

Dynamic deformation of metastable austenitic stainless steels at the nanometric length scale

Cyclic indentation was used to evaluate the dynamic deformation on metastable steels, particularly in an austenitic stainless steel, AISI 301LN. In this work, cyclic nanoindentation experiments were carried out and the obtained loading-unloading (or P-h) curves were analyzed in order to get a deeper knowledge on the time-dependent behavior, as well as the main deformation mechanisms. It was found that the cyclic P-h curves present a softening effect due to several repeatable features (pop-in events, ratcheting effect, etc.) mainly related to dynamic deformation. Also, observation by transmission electron microscopy highlighted that dislocation pile-up is the main responsible of the secondary pop-ins produced after certain cycles.Peer ReviewedPostprint (author's final draft

Censo psicossocial dos moradores em hospitais psiquiátricos do estado de São Paulo: um olhar sob a perspectiva racial

Este estudo objetivou verificar o perfil dos moradores dos hospitais psiquiátricos do Estado de São Paulo segundo raça/cor. Para isso, foi realizado um levantamento do Censo Psicossocial de moradores em hospitais psiquiátricos próprios e conveniados pelo SUS do Estado de São Paulo que estavam com tempo de internação igual ou superior a um ano, a partir de 30/11/2007. Ao caracterizar o perfil dessa população, foi identificado que a população branca é predominante nesses hospitais, totalizando 60,29% do total de moradores. No entanto, os dados de raça/cor do censo demográfico do ano 2000 informam que 27,4% da população do estado de São Paulo é preta e parda e na população moradora de hospitais psiquiátricos, esse número alcançou 38,36%. Como resultados, constatou-se uma maior proporção de negros que estão internados porque não têm renda e/ou lugar para morar. Essa população possui uma rede social frágil, recebe menos visitas, - precariedade social - associada ao transtorno mental ou doenças clínicas. Apesar de existir a Portaria GM 106/2000 que instituiu os Serviços de Residenciais Terapêuticos (SRTs) para egressos de internações psiquiátricas de longa permanência com ausência e/ou fragilidade de redes sociais de suporte, supõe-se que os negros não são contemplados por esta resolução. Os efeitos psicossociais do racismo e o impacto dos processos de preconceito, exclusão e apartamento social na saúde mental são evidenciados neste artigo
