SuperLFV: An SLHA tool for lepton flavor violating observables in supersymmetric models

We introduce SuperLFV, a numerical tool for calculating low-energy observables that exhibit charged lepton flavor violation (LFV) in the context of the minimal supersymmetric standard model (MSSM). As the Large Hadron Collider and MEG, a dedicated μ⁺→e⁺γ${\mu }^{+}\to e^{+}\gamma$ experiment, are presently acquiring data, there is need for tools that provide rapid discrimination of models that exhibit LFV. SuperLFV accepts a spectrum file compliant with the SUSY Les Houches Accord (SLHA), containing the MSSM couplings and masses with complex phases at the supersymmetry breaking scale. In this manner, SuperLFV is compatible with but divorced from existing SLHA spectrum calculators that provide the low energy spectrum. Hence, input spectra are not confined to the LFV sources provided by established SLHA spectrum calculators. Input spectra may be generated by personal code or by hand, allowing for arbitrary models not supported by existing spectrum calculators.     

程度关系型数据库

本文将符合度、真度和信度等度量引入关系型数据库,提出了程度语言值关系、真度关系、信度关系、程度关系、程度语言值-真度-信度关系和程度语言值-真度-信度-程度关系等6种关系数据模型及其运算（操作）定义,扩充了传统关系型数据库表达范围和应用领域。同时,这种“程度”的思想和方法,也可用于扩展其它类型的数据库。

悉尼自适应交通控制系统线圈数据短时多步预测双层模型

为了进一步改善悉尼自适应交通控制系统(Sydney coordinated adaptive traffic system,SCATS)线圈数据短时多步预测的效果,在对SCATS线圈数据进行预处理的基础上,设计了一种基于动态神经网络的短时多步预测双层模型,包括基于NARX(Nonlinear autoregressive model with exogenous inputs)神经网络的多步预测方法以及基于FTD(Focused time-delay)神经网络的可预测步数在线估计方法,并采用某特大城市SCATS线圈实测数据进行了验证和对比分析。结果表明:本文方法能够进一步降低SCATS线圈数据短时多步预测的误差。     

Retail Change in Southern Sydney: Lifestyle-Linked Restructuring?

Examination of the changing composition of shopping centres in suburban Sydney between 1969 and 1998 suggests that retail restructuring is linked to lifestyle changes. The growth in the number of shops appears to have matched population growth in the 1990s, suggesting that the suburbanisation of retailing has stabilised. At the same time there has been increasing diversification in terms of the retail functions which are available and in terms of the places where these are available. These changes appear linked to a blurring of the distinction between shopping and leisure and to the use of shopping as a way of signifying identity.     

New suburban centers: An Australian perspective

Suburban “edge cities” are an international phenomenon registering the impacts of a growing global economy, the increasing footlooseness of capital, advances in communication technology, the growth of hi-tech industry, and the forces of decentralisation. Yet they do assume culturally specific forms. Using the case study of North Ryde in the Sydney metropolitan area, differences between Australia and the United States in terms of the dynamism and scale of their respective edge-city environments are highlighted. Four explanatory factors are identified: the comparative nature of the Australian economy, the differential strength of planning controls, contrasting central city—suburban relationships, and a lesser degree of freeway dependence.

How does Government Procurement Law affect bidding price competition in Taiwan?

To conform with the requirements of the international Government Procurement Agreement and the regulations of the World Trade Organization, the Taiwan Government Procurement Law (GPL) was enacted in 1999. The main points of the agreement and barriers affecting price competition are illustrated. Award prices for subcentral government civil engineering projects are compared before and after the law went into effect. The result suggests that civil engineering prices have decreased significantly since the introduction of the law, that the transparent and open-tendering system enforced by the law has led to an increase in competition, and that tender prices decreased during the initial period. During the same period, construction companies' average rate of profit on sales moved from positive to negative. It is concluded that severe bidding competition is expected after Taiwan completes accession to the agreement.
