Fusarium solain is the most important pathogen of huge range of plant hosts, especially potato in the word, which causes tuber rot in storage and root rot of potato plants in fields. Fifty four isolates from potato, bean, chickpea and cucurbit (melon, watermelon and cucumber) was subjected in a study through analysis of vegetative compatibility groups (VCGs) and rep-PCR DNA fingerprinting. Nit ...

background: various techniques are used in diagnosing cardiac diseases. the electrocardiogram is one of these tools in common use. in this study vectorcardiogram ) vcg ( signals are used as a tool for detection of cardiac ischemia. methods: vcg signals used in this study were obtained form 60 patients suspected to have ischemia disease and 10 normal candidates. verification of the ischemia had ...

Many important problems in multiagent systems involve the allocation of multiple resources among the agents. For resource allocation problems, the well-known VCG mechanism satisfies a list of desired properties, including efficiency, strategy-proofness, individual rationality, and the non-deficit property. However, VCG is generally not budget-balanced. Under VCG, agents pay the VCG payments, wh...

Vectorcardiography (VCG) as an alternative form of 12-lead ECG is another method measuring the electrical activity heart. The use vectorcardiography in clinical practice not common, but VCG leads can be derived from ECG. has proven to a useful and more accurate tool for diagnosing various heart diseases within automated detection. This paper presents application four transformation methods name...

The ability to monitor mitochondrial background in Verticillium dahliae may provide an additional tool for population studies and monitoring clonal populations. Published mitochondrial genome sequences of V. dahliae (DQ351941) were used to design primers for amplification of spacer regions for assessment of mitochondrial haplotype differences among isolates. Five regions were examined (5,229 bp...

For the problem of allocating resources among multiple strategic agents, the well-known Vickrey-Clarke-Groves (VCG) mechanism is efficient, strategy-proof, and it never incurs a deficit. However, in general, under the VCG mechanism, payments flow out of the system of agents, which reduces the agents’ utilities. VCG redistribution mechanisms aim to return as much of the VCG payments as possible ...

We consider Vickrey–Clarke–Groves (VCG) auctions for a very general combinatorial structure, in an average-case setting where item costs are independent, identically distributed uniform random variables. We prove that the expected VCG cost is at least double the expected nominal cost, and exactly double when the desired structure is a basis of a bridgeless matroid. In the matroid case we furthe...

In this paper we investigate extensions of the well-known Vickrey[1961]-Clarke[1971]Groves[1973] (VCG) mechanisms to problems whose objective function is not utilitarian and whose agents’ utilities are not quasi-linear. We provide a generalization of utilitarian problems, termed consistent problems, and prove that every consistent problem admits a truthful mechanism. These mechanisms, termed VC...

Elevated ventricular repolarization lability is believed to be linked to the risk of ventricular tachycardia/ventricular fibrillation. However, ventricular repolarization is a complex electrical phenomenon, and abnormalities in ventricular repolarization are not completely understood. To evaluate repolarization lability, vectorcardiography (VCG) is an alternative approach where the electrocardi...
