Numerous criteria for the diagnosis of inferior wall myocardial infarction by electrocardiogram (ECG) and vectorcardiogram (VCG) have been published, but they have not been subjected to a systematic, independent evaluation. Accordingly, we studied 146 patients undergoing cardiac catheterization; 63 were normal and 83 had a history of infarction, a significant right coronary lesion and an inferi...

AIMS When analyzing P-wave morphology, the vectorcardiogram (VCG) has been shown useful to identify indicators of propensity to atrial fibrillation (AF). Since VCG is rarely used in the clinical routine, we wanted to investigate if these indicators could be accurately determined in VCG derived from standard 12-lead ECG (dVCG). METHODS ECG and VCG recordings from 21 healthy subjects and 20 pat...

Verification Condition Generator (VCG) tools have been effective in simplifying the task of proving programs correct. However, in the past these VCG tools have in general not themselves been mechanically proven, so any proof using and depending on these VCGs might have contained errors. In our work, we define and rigorously prove correct a VCG tool within the HOL theorem proving system, for a s...

The study aim was to construct linear transformations for derivation of McFeeParungao vectorcardiogram (VCG) from 12 standard ECG or Frank VCG and to assess the accuracy of derived electric cardiac signals (ECS) and secondarily derived VCG parameters. A large archive of VCG data recorded in the McFee-Parungao lead system have been accumulated and analyzed in the Cardiology Research Complex (Mos...

We consider a social cost minimization problem with equality and inequality constraints in which a central coordinator allocates infinitely divisible goods to self-interested N firms under information asymmetry. We consider the VickreyClarke-Groves (VCG) mechanism and study its connection to an alternative mechanism based on market clearing-price. Under the considered set up, we show that the V...

Abstract In the sponsored search auction, VCG and GSP have been compared by researchers from computer science and economics in the last few years. However, there have been some experiments not well consistent with the existing literatures. We proposed that an assumption could be refined, namely the dominant-strategy equilibrium is still the unique valid VCG equilibrium concept in the sponsored ...

For the problem of allocating one or more items among a group of competing agents, the Vickrey-Clarke-Groves (VCG) mechanism is strategyproof and efficient. However, the VCG mechanism is not strongly budget balanced: in general, value flows out of the system of agents in the form of VCG payments, which reduces the agents’ utilities. In many settings, the objective is to maximize the sum of the ...

ABSTRACT Thirty-nine isolates of Fusarium oxysporum were collected from tomato plants displaying wilt symptoms in a field in California 2 years after F. oxysporum f. sp. lycopersici race 3 was first observed at that location. These and other isolates of F. oxysporum f. sp. lycopersici were characterized by pathogenicity, race, and vegetative compatibility group (VCG). Of the 39 California isola...
