We discuss the computational complexity of the perturbative evaluation of scattering amplitudes, both by the Caravaglios-Moretti algorithm and by direct evaluation of the individual diagrams. For a self-interacting scalar theory, we determine the complexity as a function of the number of external legs. We describe a method for obtaining the number of topologically inequivalent Feynman graphs co...

Abstract Recent studies have revealed the prevalence and biological significance of guanidine metabolism in nature. However, metabolic pathways used by microbes to degrade or mitigate its toxicity not been widely studied. Here, via comparative proteomics subsequent experimental validation, we demonstrate that Sll1077, previously annotated as an agmatinase enzyme model cyanobacterium Synechocyst...

: The business line at the C59 company consists of four, namely international, retail, order, and merchandise. In merchandise business, there is a problem with this business. Namely that sales target has been set by never achieved, while opportunity still wide. As first step, identification company's external internal data carried out. There are five problem-solving models used for processing, ...

a study with travel cost method (tcm) was performed to evaluate ecotourism demand of lake belonging to karoon 3 dam. for this purpose, 220 clawson questionnaires at highest demand time (february to may 2008) were completed. results of this investigation showed that forecasting outdoor recreational value of karoon 3 dam limits is equal to 2,879,550,000 rials at month, during study. in order to p...

3-dimensional layout of graphs is a standard model for orthogonal graph drawing. Vertices are mapped into the 3D grid and edges are drawn as the grid edge disjoint paths. The main measure of the efficiency of the drawing is the volume which is motivated by the 3D VLSI design. In this paper we develop a general framework for efficient 3D drawing of product graphs in both 1 active layer and gener...

Abstract. The increasingly fierce competition between Café businessmen in Indonesia, requires these business actors to be able determine the opportunities for success and survival, it is also very small survive compete with right marketing strategy. problems this research are formulated as follows: (1) How purchasing power of local community towards culinary food products cafe seasen? (2) What ...

Energy consumption such as oil and gas which still tends to be high makes business opportunities in the energy sector considered have promising prospects. One of products that are needed by people Indonesia is LPG (Liquefied Petroleum Gas). PT XYZ a 3 kg subsidized agent company classified highly regulated industry business, namely all its activities supervised government related agencies this ...
