One-loop tests of supersymmetric gauge theories on spheres

We show that a recently conjectured form for perturbative supersymmetric partition functions on spheres of general dimension $d$ is consistent with the flat space limit of 6-dimensional $\mathcal{N}=1$ super Yang-Mills. We also show that the partition functions for $\mathcal{N}=1$ 8- and 9-dimensional theories are consistent with their known flat space limits.Comment: 14 pages. Minor modifications. References adde

Challenges and influential factors in ERP adoption and implementation

The adoption and implementation of Enterprise Resource Planning (ERP) systems is a challenging and expensive task that not only requires rigorous efforts but also demands to have a detailed analysis of such factors that are critical to the adoption or implementation of ERP systems. Many efforts have been made to identify such influential factors for ERP; however, they are not filtered comprehensively in terms of the different perspectives. This paper focuses on the ERP critical success factors from five different perspectives such as: stakeholders; process; technology; organisation; and project. Results from the literature review are presented and 19 such factors are identified that are imperative for a successful ERP implementation, which are listed in order of their importance. Considering these factors can realize several benefits such as reducing costs and saving time or extra effort

Recovering complete and draft population genomes from metagenome datasets.

Assembly of metagenomic sequence data into microbial genomes is of fundamental value to improving our understanding of microbial ecology and metabolism by elucidating the functional potential of hard-to-culture microorganisms. Here, we provide a synthesis of available methods to bin metagenomic contigs into species-level groups and highlight how genetic diversity, sequencing depth, and coverage influence binning success. Despite the computational cost on application to deeply sequenced complex metagenomes (e.g., soil), covarying patterns of contig coverage across multiple datasets significantly improves the binning process. We also discuss and compare current genome validation methods and reveal how these methods tackle the problem of chimeric genome bins i.e., sequences from multiple species. Finally, we explore how population genome assembly can be used to uncover biogeographic trends and to characterize the effect of in situ functional constraints on the genome-wide evolution

The combined harvester for paddy harvesting: the farm labourer’s perspective

The Coastal belt of the Ampara district is often regarded as the best production area for paddy which produces the highest yield of 3 500 – 4 200 kg/hectare. In the Maha season it produces 11 percent and in Yala season it produces 22 percent of total national production. Labour shortage specially for harvesting paddy was an important problem farmers faced which changes farmer practice to adopt combines Harvesters for paddy harvesting in the area. The objectives of this research were to study the impacts of combine harvesters on the displacement of labour and to find out an average economic losses for the farm labour caused. The data were collected for the study through personal interviews from the farm labourers at Nintavur ASC division. The research revealed that the combined harvesters implied positive welfare impact and financial viability; negative effects are noticed on employment opportunities and also on the income of harvesting labourers. On an average during the active harvesting period of 30 days farm labours, earned around 1650 kg of paddy which is sufficient for 6 months for their family consumption (792 kg) and the balance earned paddy could be used for other activities. Due to the adoption of combined Harvesters the farm labourers lost this earning. At the same time this loss of earning has also increased (almost doubled) the wage rate in other activities related to the paddy cultivation

Production efficiency of paddy cultivation in the eastern province

This study focused on measuring the technical efficiency ofpaddy cultivation, to explore ways of increasing yield and productivity in the Ampara and Batticaloa districts. Both primary and secondary data were used in this study. Earlier studies revealed of stagnation in production and productivity of paddy since 1995 in both districts. The primary data were gathered through personal interviews among 100 farmers from each district for Yala (irrigatedpaddy) andMaha(rainfedpaddy) during 2001/2002period. In Ampara district the areas selectedfor field survey were Ninthavur and Akkaraipattu; while in Batticaloa district the areas selected were Kalawanchikudy and Vantharumoolai. The analytical framework used in this study was the Maximum Livelihood Estimates (MLE) of the Stochastic Frontier Model estimated with the 'Frontier 4.1" computer software. Results of the study indicated significant differences in productivity, resource use and technical efficiency in both Ampara and Batticaloa districts. The average yield/acre in Ampara district in Yala was 20 % higher than in the Batticaloa district, while the figure was 8 % higher in Maha season. Total cost of production was higher in Ampara district for both seasons when compared to Batticaloa district. This was mainly attributed to the higher level of input use in Ampara district. Productive efficiency analysis indicates that the average technical efficiencies of paddy production were 64% and 82% in the Ampara and Batticaloa districts respectively. Also only about 12% and 61 % farmers in Ampara and Batticaloa districts respectively had a technical efficiency of over 80% during Maha season; while during Yala season the technical efficiency figures were 30% and 76% respectively. Overall the study revealed that Batticaloa district farmers were more efficient in production and over 60% of farmers had a technical efficiency of over 80% during Yala and Maha seasons. This is attributed mainly to small farm size in Batticaloa district. The findings suggest that increasing technical efficiency is the best approach of enhancing paddy production in both the districts. As both the two districts command a larger share of the total paddy production in the country, a concentrated effort should be made to raise their level of technical efficiency in the future.South Eastern University of Sri Lanka Oluvil # 32360 Sri Lank

A survey of simulation techniques in commerce and defence

Despite the developments in Modelling and Simulation (M&S) tools and techniques over the past years, there has been a gap in the M&S research and practice in healthcare on developing a toolkit to assist the modellers and simulation practitioners with selecting an appropriate set of techniques. This study is a preliminary step towards this goal. This paper presents some results from a systematic literature survey on applications of M&S in the commerce and defence domains that could inspire some improvements in the healthcare. Interim results show that in the commercial sector Discrete-Event Simulation (DES) has been the most widely used technique with System Dynamics (SD) in second place. However in the defence sector, SD has gained relatively more attention. SD has been found quite useful for qualitative and soft factors analysis. From both the surveys it becomes clear that there is a growing trend towards using hybrid M&S approaches
