Different methods for the calculation of cross sections with many QCD particles are compared. To this end, CSW vertex rules, Berends-Giele recursion and Feynman-diagram based techniques are implemented as well as various methods for the treatment of colours and phase space integration. We find that typically there is only a small window of jet multiplicities, where the CSW technique has efficie...

Abstract: The similarity of massive CSW scalar vertices and quark vertices can be understood using a kind of light-cone SUSY transformation presented in this paper. We also show that the canonical transformation generating the MHV-SQCD lagrangian, can be fixed by applying this light-cone SUSY transformation to the canonical transformation for MHV-QCD obtained in paper arxiv:0805.0239. Most of t...

OBJECTIVES To assess prevalence of HIV and sexually transmitted infections (STIs), risk behaviours, and demographics in male commercial sex workers (CSWs)/prostitutes in Sydney. METHODS Retrospective, cross sectional study with two comparison groups. Demographic, behavioural, and morbidity data were analysed from standardised medical records of patients attending a public STI and HIV service ...

The distribution of OGC Web Catalogues (CSW) across professional communities, the expert profile of the catalogue user and also the low coverage of OGCWeb Services (OWS) in standard search engines reduce the possibility of discovery and sharing geographic information. This paper presents an approach to simple spatio-temporal search of OWS retrieved from the web by a specialized crawler. The Dig...

Data envelopment analysis (DEA) has been recently employed for performance and efficiency evaluation of decision-making units (DMUs) with multiple inputs outputs. Complex internal relations within a DMU required more accurate DEA models than existing classic DEA. In real world applications, shared resources, among stages supply chain, is great interest managers decision makers. Unfair allotment...

OBJECTIVES Accurate mu maps are important for quantitative image reconstruction in SPECT. The Compton scatter energy window (CSW) technique has been proposed to define the outline of objects. In this technique, a lower energy window image is acquired in addition to the main photo-peak energy window. The image of the lower energy window is used to estimate the edge of the scanned object to produ...

Cerebral salt wasting (CSW) syndrome is an important cause of hyponatremia in head injuries apart from syndrome of inappropriate antidiuretic hormone (SIADH). Proper diagnosis and differentiation between these two entities are necessary for management as the treatment is quite opposite in both conditions. Fludrocortisone can help in managing CSW where alone saline infusion does not work. We rep...

This paper presents exible support for asynchronous sharing (later-time use) of computer-supported workspaces (CSWs), or simply replayable workspaces. Through the interactive replay of a previously recorded CSW session, it is possible to reuse valuable collaborative information. The session is represented through heterogeneous media streams each containing state and inputs to a CSW tool. We pre...
