It is important to pursue simulations with Wilson-like fermions, despite their greater computational cost than staggered fermions, because one avoids the theoretical uncertainty associated with taking roots of the fermion determinant. One drawback with Wilson fermions is that they lead to discretization errors of O(a), slowing the approach to the continuum. This can be ameliorated using anO(a) ...

Achieving a flexible and efficient geospatial Sensor Observation Service (SOS) is difficult, given the diversity of sensor networks, the heterogeneity of sensor data storage, and the differing requirements of users. This paper describes development of a service-oriented multi-purpose SOS framework. The goal is to create a single method of access to the data by integrating the sensor observation...

It has been conjectured that every (2+1)-TQFT is a Chern-SimonsWitten (CSW) theory labelled by a pair (G, λ), where G is a compact Lie group, and λ ∈ H(BG;Z) a cohomology class. We study two TQFTs constructed from Jones’ subfactor theory which are believed to be counterexamples to this conjecture: one is the quantum double of the even sectors of the E6 subfactor, and the other is the quantum do...

HIV infection in the Republic of Moldova continues to represent a major problem of public health, which is kept under constant surveillance and monitoring. On January 1, 2014 the cumulative number of persons identified with HIV was 8,588 people, representing a prevalence of 166.74 cases per population of 100,000. In 2013, HIV incidence was 17.18 cases per 100,000 population. Cumulative AIDS was...

Supply chain management is the combination of art and science that goes into improving the supply chain. In some cases of supply chain especially two-stage process, differing weights for the same factors, may not acceptable. The purpose of this paper is a performance evaluation of two-stage using DEA and based on a CSW model and this method for ranking two-stage and could be used to measure the...

Classification of professional and non-professional female sex workers (FSWs) into different categories, never previously reported in the Central African Republic (CAR), may be useful to assess the dynamics of the human immunodeficiency virus (HIV) epidemic, design operational intervention programmes to combat HIV and other sexually transmitted infections (STIs) and to adapt these programmes to...

Remarkable progress inspired by twistors has lead to very simple analytic expressions and to new recursive relations for multi-parton color-ordered amplitudes. We show how such relations can be extended to include color and present the corresponding color-dressed formulation for the Berends-Giele, BCF and a new kind of CSW recursive relations. A detailed comparison of the numerical efficiency o...

Using newly proposed recursion relations in [25, 26], compact formulas are obtained for tree-level amplitudes of g− 1 g − 2 g − 3 g + 4 g + 5 · · · g + n . We then make an extension of these recursion relations to include fermions of multi-flavors, from which MHV and MHV amplitudes are reproduced. We also calculate non-MHV amplitudes of processes with two fermions and four gluons. Results thus ...
