BACKGROUND In Cardiovascular Magnetic Resonance (CMR), the synchronization of image acquisition with heart motion is performed in clinical practice by processing the electrocardiogram (ECG). The ECG-based synchronization is well established for MR scanners with magnetic fields up to 3 T. However, this technique is prone to errors in ultra high field environments, e.g. in 7 T MR scanners as used...

We consider auctions in which the players have very limited knowledge about their own valuations. Specifically, the only information that a Knightian player i has about the profile of true valuations, θ∗, consists of a set of distributions, from one of which θ∗ i has been drawn. The VCG mechanism guarantees very high social welfare both in singleand multi-good auctions, so long as Knightian pla...

We examine the effect of false-name bids on combinatorial auction protocols. Falsename bids are bids submitted by a single bidder using multiple identifiers such as multiple e-mail addresses. The obtained results are summarized as follows: 1) The Vickrey-Clarke-Groves (VCG) mechanism, which is strategy-proof and Pareto efficient when there exists no false-name bids, is not false-name-proof, 2) ...

Isolates of Pyricularia grisea from wheat (Triticum aestivum Lam.) and triticale (x Triticosecale Wittmack) spikes with blast symptoms were analyzed by classical (VCG) and molecular (RAPD) techniques. P. grisea mutants, unable to use sodium nitrate (nit) as nitrogen source, were obtained with potassium chlorate. For vegetative compatibility (VCG) tests, genetically complementary nit mutant pair...

A VCG auction (named after their inventors Vickrey, Clarke, and Groves) is a generalization of the single-good, second price Vickrey auction to the case of a combinatorial auction (multiple goods, from which any participant can bid on each possible combination). We formalize in this entry VCG auctions, including tie-breaking and prove that the functions for the allocation and the price determin...

In Australia, indigenous Fusarium oxysporum consist of at least five genetically distinct lineages and the two strains (VCG 11&12) of F. oxysporum f. sp. vasinfectum (Fov) are genetically related to lineage A, suggesting that they evolved locally. This is consistent with the observation that virulence of a lineage A isolate increased after 10 successive infections on susceptible cotton in the g...

This study examined the field of visualizations in computer graphics (VCG) using bibliometric methods, including performance and science mapping analysis. A dataset documents from SCOPUS, 1986 to 2019, was analyzed visualized VOSviewer. The results showed an increasing trend new VCG. five most cited publications were all related data visualization software. prolific authors, by Citation per Pap...
